Abstract: This study focused on the Islamic banking role in mitigating income disparity in Indonesia. The facts show that the financing held by Sharia-Based Commercial Banks and Sharia Business Units provides a positive  and  significant  correlation  with  the  level  of  disparity  (inequality)  of  people’s  income,  namely  the  probability  value of 0.027 < 0.005. Meanwhile, the financing carried out by the Islamic People’s Financing Bank also has a  positive effect on the level of disparity in people’s income with a probability value of 0.0193 <0.05. The cause  of the increasing disparity in people’s incomes is due to the distribution of financing which is dominated by the  consumptive  sector  such  as  financing  with murabahah  contracts,  rather  than  other  financing  based  on  profit  sharing. In Islamic commercial banks and sharia business units, financing with murabahah contracts from 2014 to 2018 will be totaled Rp. 6,573,270,000 and in Islamic people financing banks it is worth Rp. 26,356,152,000. 

However, if you look at the Gini ratio from 2014 to 2018, it has decreased gradually, this is because the government, in this case the Ministry of Agriculture, is trying to improve people’s welfare through various mechanization  programs  and  massive  infrastructure  development.  This  effort  is  made  to  reduce  the  number  of poor people and reduce income inequality. The population living in rural areas reaches 60%, where most of them are farmers with 70% of their main income coming from the agricultural sector.

Keywords: Islamic banking; disparity; income.

Abstrak: Penelitian ini mengungkapkan peranan perbankan umum yang berbasis syariah dalam menurunkan disparitas pendapatan. Fakta menunjukkan bahwa pembiayaan yang diselenggarakan oleh Bank Umum berbasis Syariah  dan  Unit  Usaha  Syariah  memberikan  korelasi  yang  positif  dan  signifikan  dengan  tingkat  disparitas  pendapatan masyarakat yakni nilai probabilitas 0.027 < 0,005. Sedangkan untuk pembiayaan yang dilakukan oleh  Bank Pembiayaan Rakyat Syariah juga berpengaruh positif terhadap tingkat disparitas pendapatan masyarakat dengan  nilai  probabilitas  0.0193  <  0,05.  Adapun  penyebab  meningkatnya  disparitas  pendapatan  masyarakat  yaitu disebabkan oleh penyaluran pembiayaan yang lebih banyak didominasi oleh sektor konsumtif seperti pembiayaan dengan akad murabahah, dari pada pembiayaan lain yang berbasis bagi hasil. Pada bank umum syariah dan unit usaha syariah pembiayaan dengan akad murabahah dari tahun 2014 hingga tahun 2018 jika ditotalkan akan bernilai Rp.6.573.270.000 dan pada bank pembiayaan rakyat syariah bernilai Rp.26.356.152.000.

Namun, jika diihat pada nilai rasio gini dari tahun 2014 hingga tahun 2018 telah mengalami penurunan secara bertahap hal ini dikarenakan pihak pemerintah yang dalam hal ini merupakan Kementerian Pertanian berupaya meningkatkan kesejahteraan masyarakat melalui berbagai program mekanisasi dan pembangunan infrastruktur secara masif. Upaya ini dilakukan untuk menurunkan jumlah penduduk miskin dan mengurangi ketimpangan pendapatan masyarakat. Penduduk yang tingggal di pedesaan jumlahnya mencapai 60%, dimana sebagian besar dari mereka merupakan petani dengan 70% pendapatan utamanya berasal dari sektor pertanian.

Introduction

Economic disparity phenomena often become a critical problem in developing country, mostly because the economic disparity. The Interpreter, Lowy Institute website on an article “Indonesia: the not so good news” published on Monday, February,

3rd 2020 reported that indeed Indonesia is wealthy country, however the society are still poor, because the new wealthy of Indonesia is not distributed well. The pelt of four ballooners in Indonesia, who have 25 billion US Dollar income or equal to the income of 100 million poor people in Indonesia.

(2)

Todaro and Smith argued that the most popular indicator to measure the disparity level is Gini ratio. World Bank divided the population number into 3 (three) categories, namely 40%

group have low income, 40% group have standard income, and 20% group have high income, to measure income distribution.1 The higher the unbalanced distribution, the higher the economic disparity. Data were reported before indicated that Indonesia has high economic disparity.2

The Central of Statistic Institution called Badan Pusat Statistik (BPS) data on Maret 2021 showed that the level of expenditure of Indonesia people based on Gini ratio is 0,384. This score was decreased 0,001 point, compared by the Gini ratio on September 2020, namely 0,385, and increase 0,003 point, compared by Gini ratio on March 2020, namely 0,381. Gini ratio is different between urban  area and rural area, Gini ratio was recorded 0,401 in urban area on March 2021, increase 0,399 from Gini ratio on September 2020 and Gini ratio 0,393 on March 2020. Meanwhile, Gini ratio was recorded 0,315 in rural area on March 2021, decrease 0,319 with Gini ratio on September 2020 and 0,317 Gini ratio on March 2020.

Indonesia Gini ration undergo fluctuation since 2010 to September 2014, however on March 2015 to September 2018, it tends to decrease.

This condition showed that since March 2015 to September 2018, there was corrective to the expenditure or income distribution.

While when viewed from the area of residence, the Gini ratio in urban areas shows that  in  September  2018  it  was  0.381.  This  figure  shows that there has been a decrease of 0.010 points compared to March 2018 which was 0.401.

When compared to the figures in September 2017,  the figure decreased by 0.013 points. In rural areas,  the  Gini  ratio  figure  in  September  2018  was recorded at 0.319, which was down by 0.005 points when compared to conditions in March 2018 and decreased by 0.001 points when compared to conditions in September 2017. While the Gini ratio value in March 2018 and September 2017 were recorded at 0.324 and 0.320, respectively. The distribution of data can be seen in the following figure.

Absolutely, the degradation of Gini ratio was excellent achievement and need to be appreciated, however the government should get more correction to anticipate the negative impact toward the disparity level and population welfare.

It was explained before that disparity will increase the poverty of society.

Islamic banking regulation no.21/2008 concerning Islamic banking chapter 1 verses 7 explains that Islamic banking is a bank which manage its systems under the Islamic law. There are two types of Islamic bank, namely General Islamic Bank and Islamic Finance bank. Islamic bank offers some type of financial products, by managing  profit sharing, Islam term is (mudharabah), equity capital (musharakah), buy and sell products to get profit (murabahah), absolute rent (ijarah), or the choice to transference of ownership of goods which is rent by bank to others (ijarah wa iqtina), Charity Contract, istithna Contract’, leasing

(3)

by ownership (ijarah al-muntahiya bi al-tamlîk), and others contract and do not contradicted by Islamic Bank.3

Financial service based on Islamic banking, its implementation has been expanded by forming sub system which also based on Islamic banking system. It can be categorized into two in accordance  to  its  significance  to  society,  namely:

1.  The productive financial, consisted to liquidity  financial  and  general  financial.

2.  Consumptive  financial  both  secondary  and  primary.4

Graphic Asset Growth, PYD, and DPK

Based on the graphic above, it can be seen the  growth  of  asset  score,  disbursed  financing,  and  third-party  financial.  The  third-party  financial  in Islamic banking has showed positive trend and good work performance. Achil R Djayadiningrat stated that Islamic bank does not give negative effect to conventional bank, however it completed  the society need, especially for Moslem who considered that interest system is usury.5 Bank has moral  responsibility  to  distribute  society  finance  or financial intermedidiary. Banking is also an agent of development, namely the distribution of development results, as well as national stability towards increasing the standard of living of the people at large.6 Law no.21/2008 concerning Islamic banking has mandated Islamic banking to support and support the implementation of nation building for the sake of creating justice,

togetherness and equitable distribution of welfare.

Thus, the presence of Islamic banking is expected to contribute to the creation of conditions in accordance with the objectives of the law, at least in the spirit of achieving these goals, it can reduce or reduce the gap in income disparities in the community.

Asaad7 has revealed that the Islamic banking sector has a very important role to support the implementation of development, especially the agricultural sector, because the majority of Indonesia’s population relies on the agricultural sector. The agricultural sector has contributed to the absorption of labor for the nation’s economic growth, although the fact is that it is precisely from people who work as farmers that the highest level of disparity occurs. Meanwhile, Hidayat8 argues that the Islamic banking sector in Indonesia has not run according to what is expected by Law no.

21 of 2008, where the results of his research prove that the distribution of Islamic bank financing has  a positive effect on the Gini ratio. This means that  the greater the amount of financing disbursement  carried out by Islamic banking, the greater the disparity in people’s income.

Purwanto’s research,9  states  that  financing  carried out by Islamic Commercial Banks and Sharia Business  Units  has  a  significant  positive  impact  on the level of community income disparity. This is  because  the  financing  carried  out  by  Islamic  Commercial Banks and Sharia Business Units is dominated by murabahah contracts, while the financing carried out by Islamic people’s financing  banks  has  no  significant  effect  on  the  level  of  disparity in people’s income. However, it is possible that the financing carried out by the Islamic People’s  Financing  Bank  can  affect  the  level  of  income disparity in the community. This is because the financing carried out is also more dominated  by murabahah contracts. Ikhwanuddin Harahap’s

research,10 states that there is a relationship between Islamic banking and the resilience of a country’s economy. Although it still has to do optimization in various aspects of people’s lives.

The better the function and implementation of Islamic banking operations in a country, it is expected that the greater its contribution to the economic growth of a country will be. Research by Linda Tamin Umairoh Hasyim,11 states that the  financing  provided  by  Islamic  banking  has  a  positive  effect  on  economic  growth  in  the  real  sector  in  Indonesia.  The  more  financing  that  is  channeled for production activities in the real sector in the community will have an impact on economic growth. Rendy Okryadi Putra’s,12 states that the total number of Islamic banking assets is still relatively small when compared to the total assets of conventional banks so that Islamic banking assets do not have much effect on  supporting Indonesia’s economic growth. Islamic banking financing has a positive effect on economic  growth in Indonesia, because it can help people get capital to invest.

The studies that have been stated above have several similarities, namely the research above explains how the current development of Islamic banking is and how the contribution of Islamic banking to the improvement of people’s welfare. Financing carried out by Islamic banking will certainly help in improving the welfare of the community if it is followed by an increase in public interest  in  conducting  transactions  and  financing  through Islamic banking. So that further research is  needed  to  find  out  whether  Islamic  banking  financing can affect the level of disparity, as well  as how big the contribution of Islamic banking financing  to  people’s  income  disparities  and  to  find out what kind of financing can affect people’s  income disparities. Based on the background that has been stated, the focus of the problem in this

study is “Islamic Banking and Its Contribution to Income Disparities in Indonesia”. The formulation of the problem is; Can the contribution of Islamic banking  financing  affect  the  income  disparity  of  people in Indonesia?”

Method Data source

The type of data in this study is secondary data. Secondary data is data obtained indirectly or archive research containing past events. This secondary data can be obtained by researchers from journals, magazines, books, and statistical data and from the internet related to the contribution of Islamic banking financing to income  disparities in Indonesia.13

Data collection technique

To obtain accurate data, the researchers used several data collection techniques as follows:

1. Observation is the basis of science, in the sense of facts about the world of reality which are obtained through observation.14 In a broad sense, observation is not only limited to observations made with one’s own eyes.

This method is used by the author to observe directly the situation of the level of inequality in Indonesia through the data that has been obtained by the author.

2. Documentation, namely a record of events that have passed either in the form of writing, pictures, and monumental works of someone.15

The data in question are Islamic banking statistics and Gini ratio data for 2014-2018. Statistical data on Islamic banking as well as data on the Gini ratio can be obtained online. The data that has been collected is then analyzed. The form of data in this study is semester data, namely data that is reported every six months in this study in March and September 2014–2018.

Technique analysis data

The data analysis technique in this research is using panel data regression method. The use of panel data in this study is because the data in this study is a combination of cross section data and time series data. According to Nachrowi and Usman16 in the analysis of panel data regression data, there are several techniques offered, namely:

1. The Ordinary Least Square method or commonly known as the common effect.

This technique assumes that the existing combined data (time series and cross section) show the actual conditions. The results of the regression analysis are considered valid for all objects at all times. The regression equation in the common effects model can be written as follows:

yit =  α  +  X’ itβ  + Ɛit description : i = area t = year

2. Fixed effect regression model (fixed effect).

Fixed  effect  here  means  that  an  object  has  a constant that is constant in magnitude over time (time invariant). This method also assumes that the slope is the same between objects and between times, so generalization is often added by including dummy variables to allow for different  parameter values, both across unit cross sections and  between  different  times.  can  be  written  as  follows.

3. Model random effect.

This model does not use quasi-variables but uses residuals which are thought to have a relationship between time and between objects.17 The equation of the random effects model can be  written as follows

Income Distribution Inequality

Inequality is a condition that is not evenly distributed between one another. Inequality in development also still occurs at this time between developed and developing countries, developed countries have high knowledge in terms of human resources and can process their natural resources effectively and efficiently, while developing countries that do not have good human resources do not process natural resources effectively.

According to Andrinof A. Chaniago Inequality is

“the fruit of development that only focuses on the economic aspect and forgets about the social aspect.18 And according to Budi Winarno, inequality is the result of the failure of development in the era of globalization to meet the physical and psychological needs of citizens.19

According to Syafrizal, the inequality that occurs between regions is caused by “differences  in the wealth of natural resources owned and differences  in  demographic  conditions  found  in  each  region,  so  that  each  region  has  different  capabilities in the development process”.20 The difference  in  this  region  gives  rise  to  developed  regions and underdeveloped regions. The distribution of national income reflects the equitable or unequal distribution of the results of a country’s development among its population.21

The prosperity of society is not only based on the size of the national income and per capita income, but also how the national income is distributed, whether the national income is distributed evenly or unequally. Income is considered to be perfectly distributed if every individual gets an equal share of the economy’s

output, and conversely the distribution of income is considered unfair if most of the national output is controlled by a small part of the population, but it can be very unfair if most of the national output is enjoyed by a few groups of people just.22

According to Taft Morris (lincolin Arsyad) there are eight things that cause inequality in income distribution in developing countries, namely23: 1. High population growth which can result in

a decrease in per capita income.

2. Inflation in which the income of money increases but is not followed in proportion to the increase in the production of goods.

3. Inequality of development between regions.

4. There is a lot of investment in capital-intensive projects, so that the percentage of working capital income is greater than the percentage of income that comes from community work, resulting in an increase in the unemployment rate.

5. Low social mobility.

6. Implementation of import substitution industrial policies that result in an increase in the prices of industrial goods to protect the businesses of the capitalist group.

7. Deteriorating exchange rates for developing countries in trade with developed countries, as a result of the inelastic demand for developed countries for NSB (National Science Board) export goods.

8. The destruction of folk craft industries such as carpentry, home industries, and others.

Analysis of Islamic Bank Financing and Gini Ratio

This research was conducted by processing and analyzing  data  on  Islamic  bank  financing  and  the  Gini ratio in order to obtain the final results of this  study.  The  data  on  Islamic  bank  financing  and  the  Gini ratio can be obtained online at the ojk and bps websites, then the data that has been collected is analyzed.

To estimate the model, panel data regression was used which was carried out in three ways,

(7)

namely common effect, fixed effect, and random  effect. In statistics, significant means it is possible  or likely to be true, not true by chance (probably true).  As  for  determining  the  value  is  significant  or not significant can be measured using the level  of significance (significance levels). The level of  significance  is  usually  indicated  by  the  sign  .05 (in Indonesian it becomes 0.05) or .01 (in Indonesian it becomes 0.01). Significant level (sig.)  is often changed to a level of confidence (p.value)  denoted by the number 95% or 99%. So, sig. 0.05

= p.value 95%, while sig. 0.01 = p.value 99%. If the number (computer result) obtained from statistical analysis is greater than the standard number  at  the  significance  level,  it  is  said  that  there  is  a  significant  correlation.  Following  are  the estimation results using three methods:

a. Common Effect

The  common  effects  model  is  the  simplest  panel data approach. This model does not pay attention to individual dimensions and time so it is assumed that the behavior between individuals is the same in various periods of time. This model only combines time series and cross section data in the form of a pool, estimating it using a pooled least square approach. The following are the results  of  the  estimation  of  the  Common  Effect  model:

Common  Effect  Estimation  Results

Source: Output eviews 10 (2019)

From table above, it can be seen that for the X1 variable, namely Islamic Commercial Banks and Sharia  Business  Units,  the  common  effect  model  has  a  significant  effect  on  disparity.  This  can  be  seen from the results of the variable probability

obtained, if the value is <0.05 then the results will  be  significant.  In  the  table,  it  can  be  seen  that  the  financing  of  Islamic  Commercial  Banks  and  Sharia  Business  Units  is  worth  0.0227  <  0.05,  so  the  results  have  a  significant  effect  on  disparity. 

While the variable X2 is the financing of the Islamic  People’s Financing Bank with a value of 0.0193

<  0.05,  so  it  can  be  said  that  the  results  have  a  significant  effect  on  disparity.

b. Fixed Effect

Fixed effects model assumes that there are different effects between individuals. The difference  can  be  accommodated  through  the  difference in the intercept. The following are the  results  of  the  fixed  effect  estimation:

Table  4.  Fixed  Effect  Estimation  Results

Source: Output eviews 10 (2019)

From table above, it can be seen that the X1 variable, namely the financing of Islamic Commercial Banks and Sharia Business Units, has no  significant  effect  on  the  disparity,  this  can  be  seen from the probability value, which is 0.1812 >

0.05, while the X2 variable, namely the financing of  Islamic People’s Financing Banks, has a significant  effect. to disparity, this is because the probability  value  is  0.0186  <  0.05

c. Random Effect

In  contrast  to  the  fixed  effects  model,  the  specific  effects  of  each  individual  are  treated  as  part of the error component which is random and uncorrelated with the observed explanatory

(8)

variables, such a model is called the random effects  model (REM). This model is often referred to as the error component model (ECM).

The following are the results of the random effect  estimation:

Based on table above, it is known that the X1  variable  (Islamic  Commercial  Bank  financing  and Sharia Business Unit) and the X2 variable (Islamic  People’s  Financing  Bank  financing)  have  no  significant  effect  on  the  disparity.  This  can  be seen from the probability value of the two variables greater than 0.05.

Model Fit Test

In order to find out which model is the most  appropriate to use, several model tests are carried out. The first is the Chow test to find out the right  model between Poopled Least Square (common effect)  or  fixed  effect.  The  second  LM  test  was  carried  out  to  find  out  the  right  model  between  Pooled Least Square (common effect) or random  effect.  The  third  Hausman  test  is  carried  out  to  find out the right model between random effects  or fixed effects. Here are the results of the Chow  Test:

Table 6. Chow Test Results

Source: Output eviews 10 (2019)

In order to find out which model is the right  one to use, it can be seen from the probability value of chi square (cross-section chi square). If the value is > 0.05, then the correct model is Pooled Least Square (H0) and vice versa if the probability value of chi square <0.05, then the correct model  is fixed effect (H1). After the Chow test is done, if  the  selected  method  is  the  common  effect  (H0),  the test is complete, so there is no need to do the  Hausman  test.  On  the  other  hand,  if  a  fixed  effect is selected, it is necessary to continue testing  to the Hausman test. Based on the results of the Chow test obtained, it can be concluded that the right method to be used is the Pooled Least Square (common  effect)  model,  so  there  is  no  need  to  continue testing the Hausman Test model.

Contribution of Islamic Banks to Income Inequality in Indonesia

Based on the results of the analysis that has  been  carried  out  using  the  common  effect  method (see table 2), it is known that both the financing  variable  for  Islamic  Commercial  Banks  and Sharia Business Units and the Islamic People’s Financing Bank variable are variables that have a significant effect on disparity. This can be seen in  the probabilities of Islamic commercial banks and

(9)

Islamic business units with a value of 0.0227 < 0.05  and Islamic people’s financing bank variables which  have  a  value  of  0.0193  <  0.05,  which  means  that  it  has  a  significant  effect  on  disparity.  Financing  carried out by Islamic banks has a significant effect,  meaning that financing carried out by Islamic banks  can increase the disparity rate. Based on the results of this study, this is because the financing carried  out by Islamic banks, both Islamic commercial banks and sharia business units as well as Islamic people’s  financing  banks  is  more  dominated  by  financing in murabahah contracts which are more  involved in the consumptive sector.

Financing aimed at the consumptive sector will not  increase  business  fields  and  increase  people’s  income,  this  type  of  financing  will  even  reduce  people’s income because they have to pay a margin as  compensation  for  the  financing,  so  things  like  this will create gaps in society. The following is data showing the percentage of financing in various  sectors:

Chart Percentage of Islamic Banking Transactions

Source: Islamic Banking Snapshot (March 2019)

The graph shows that transactions in the consumption sector are more dominated than other  sectors.  This  is  what  can  cause  financing  carried out by Islamic banks to increase income disparities, so it is necessary to increase transactions in productive sectors such as investment and working capital. The transactions carried out by Islamic  banking  can  be  categorized  into  the  five  largest sectors, including:

1. The household sector is 41.90%

2. The wholesale and retail trade sector is 10.23%

3. The construction sector is 8.31

4. The manufacturing industry sector is 7.75%

5.  The  financial  intermediary  sector  is  5.61%

The five largest sectors can be grouped into the  consumptive sector and the productive sector. The consumptive sector consists of household sector by 41.90%, construction sector by 8.31%, and working capital by 32.69%. Meanwhile, the productive sector consists of the wholesale and retail trade sector at 10.23%, the manufacturing industry sector at 7.75%,  and  the  financial  intermediary  sector  at  5.61%. So that because Islamic bank transactions in the form of consumption are carried out more than transactions in the form of productive.

When viewed from the statistical data of Islamic  banking  from  2014  to  2018  financing with  murabahah contracts is still more dominant than other  contracts.  This  data  shows  that  financing  carried out by Islamic Commercial Banks and Sharia Business  Units  as  well  as  financing  carried  out  by  Islamic  people’s  financing  banks  from  2014  to  2018 was dominated by financing with murabahah  contracts. In Islamic commercial banks and sharia  business  units,  financing  with  murabahah  contracts from 2014 to 2018 will be totaled Rp.

6,573,270,000,000 and at Islamic people financing  banks it is worth Rp. 26,356,152,000,000. The following is the percentage data for bank financing  contributions. sharia in various types of contracts:

GRAPHIC

Sumber: Islamic Banking Snapshot (March 2019)

The viewed from the graph, it will be seen that of the 6 compositions of financing contracts  carried out by both Islamic Commercial Banks and Islamic Rural Financing Banks, it is more dominated by financing with murabahah contracts and even  tends to increase every year. So it can be seen that  the  financing  carried  out  by  Islamic  banks  can increase the disparity of people’s income.

Meanwhile, in the graph, it can also be seen that financing  with  musharaka  contracts  has  a  fairly 

(10)

high percentage, besides murabahah, musyarakah contracts also include financing contracts engaged  in the consumptive sector.

According to the nature of its use, financing  can be divided into two, namely productive financing and consumptive financing. Meanwhile,  according to the need, financing can also be divided into two, namely working mode financing  and  investment  financing.  In  addition  to consumptive and productive financing, Islamic  banks also provide working capital financing for entrepreneurs who need additional working capital, both for the purpose of purchasing raw materials, payment of production costs, procurement of goods and services, project work as well as for other working capital needs.  The  type  of  financing  contract  offered  can be chosen according to need, using a sale and  purchase  scheme  (murabahah)  or  a  profit- sharing partnership scheme (mudharabah and musyarakah). Based on this explanation, as well as murabahah contracts, Musyarakah contracts can also be said to be engaged in the consumptive sector so that financing with Musyarakah contracts  can also increase the disparity of people’s income.

Islamic banks in Indonesia tend to prefer financing  with  a  relatively  low  risk  value.  The  dominance  of  murabahah  financing  compared  to other types of contracts actually proves the assumptions that rationally, to maintain profitability and efficiency and manage financing  risk, Islamic banks will tend to maximize financing  under murabahah contracts compared to other contracts.

One of the reasons for the financing risk faced by Islamic banking is the unique character of the financing contracts that are channeled by  the  characteristics  of  the  financing  contracts,  which can guide Islamic banks to understand the financing  risk  profile  so  that  they  can  determine  the right strategy in tackling the risks that occur to achieve optimum results. from its operational activities. Each contract has the characteristics of credit risk, price risk, operational risk, liquidity risk and  risk  at  different  levels,  which  are  described  in the following table.

Table 7. Risk Level of Each Financing Contract

Murabahah 2,56 2,87 2,67 2,93 2,76

Mudharabah 3,25 3,0 2,67 3,08 3

Note:  a  scale  of  1  to  5,  where  1  is  the  least  risky  financing  and  5  is  the  most  risky  financing.

From the table above, it can be seen the reasons why murabahah contract financing is more  in demand by the public. This is because the level of risk owned by the murabahah contract is lower than other contracts. In practice, Islamic banks use more murabahah schemes in financing distribution. 

The  definite  characteristics  of murabahah in the amount of installments and margins also give birth to the perception that the use of murabahah contracts  can  reduce  the  level  of  financing  risk. 

Although the ijarah contract can be said to have a low level of risk as well, if it is seen from the previous data (graph 4.9) which explains how big the percentage of financing using sharia contracts  is,  financing  with ijarah contracts is still slightly utilized, which is 3.2% compared to financing with  a murabahah contract that is equal to 48.24%.

There are two arguments to explain why financing using a murabahah contract can increase income disparities, namely:

1. Financing with murabahah contracts, which are generally only consumptive in nature, does not improve economic stability, especially if it is pragmatic in the short term.

2. Determination of the margin in the murabahah contract  is  more  profitable  for  the  owner  of  the capital because it will get a big profit, this  is because the murabahah contract is basically a sale accompanied by an addition or margin, while for the recipients of financing will only  get goods without getting income from the results of murabahah financing.

Financing carried out by Sharia Commercial Banks and Sharia Business Units as well as Sharia Rural  Financing  Banks  can  have  a  positive  effect 

(11)

on  income  disparity,  which  means  that  financing  by Sharia Banks can increase the disparity of people’s  income  due  to  the  effect  of  economic  financialization.  Financialization  is  a  term  used  to  describe the dynamics of the relationship between the financial sector and the real sector, namely the  increasingly dominant role of financial actors and  institutions in economic activity. The automotive industry,  for  example,  is  now  increasing  profits  from the insurance, leasing and vehicle loan businesses, compared to profits from vehicle production itself. The influence of financialization  on income distribution can be grouped into three channels, namely:

1. There is an increase in income from rent- seeking economic activity.

2.  An increase in income in the financial sector,  which is usually in the form of bonuses, causes the income distribution gap to widen.

3. Financialization has shifted the balance of power  between  financiers  and  workers  in  a  variety of ways from changes in corporate governance to the increased opportunities opened to companies by the globalization of finance.

The profit of Islamic banking can be guaranteed  because of the determination of the margin, while the  recipient  of  the  financing  will  not  necessarily  be able to increase their income. So that the more financing  using murabahah contracts, basically it will increase the income of the owners of capital, namely Islamic banking, while the people who are the  recipients  of  financing  cannot  increase  their  income.

However, if we look at the Gini ratio value that has been stated previously, it can be said that the Gini ratio value from 2014 - 2018 both in urban and rural areas continues to decrease gradually. So that it can be interpreted that the level of disparity in Indonesia has decreased, if the level of disparity decreases, it can also be said that the level of poverty also decreases. This is because  the  government’s  efforts,  especially  in  the agricultural sector, have yielded good results.

The Ministry of Agriculture continues to strive to improve the welfare of the community through various mechanization programs and massive  infrastructure  development.  This  effort 

is made to reduce the number of poor people and reduce income inequality. The population living in rural areas reaches 60%, where most of them are farmers with 70% of their main income coming from the agricultural sector. So that it can be  said  that  the  financing  carried  out  by  Islamic  banks in the agricultural sector also has a major role in reducing the level of poverty or the level of inequality in society.

Financing in the consumptive sector as described previously can increase the level of disparity, on the contrary, financing in the productive sector, be it the agricultural sector, industrial sector, trade sector, and other productive sectors can reduce the level of disparity or the level of inequality in society.

One of the Islamic  banking financing that is  often implemented with agricultural businesses is bai’ al-salam. The concept of bai’al-salam is a sale and purchase contract in which the buyer pays the price for the goods whose specifications have  been stated, while the goods to be traded will be delivered later on the agreed date. However, when viewed based on the data obtained, the public’s  interest  in  financing  the  bai’  al-salam  contract is still lacking compared to other contract financing.

The presence of Islamic banking institutions is very appropriate to develop the agribusiness sector or agricultural businesses, both commercial banks and Islamic people’s financing banks. This is  because, Islamic banks use profit-sharing schemes  (mudharabah, muzara’ah, and musyarakah), in addition to other schemes such as buying and selling greetings and murabahah. The agricultural production sharing system, especially for rice crops, takes place between the cultivators and the owners of land capital with relatively diverse profit  sharing  proportions.

There are several problems that cause the lack of role of Islamic banks in agribusiness financing,  including:

1.  The  financing  provided  by  Islamic  banks  to  agribusiness businesses is still less compared to other businesses, some of the contributing factors include: the character of farmers who have a consumptive lifestyle, so they are easily deceived by parties such as middlemen, which

(12)

ultimately results in farmers living in poverty.

poverty.

2. Farmers manage their farming business in an unprofessional way due to the lack of ability of farmers to manage their business properly, as well as the government’s lack of attention to agricultural business which is the basis of all other types of business, including in terms of price certainty.

3.  Farmers  find  it  difficult  to  get  the  legality  of  their business so they do not get the trust of Islamic  banking  to  provide  Islamic  financing.

4. Farmers’ lack of knowledge of sharia banking is due to the location of sharia banking which tends to be far from agricultural businesses, little introduction by sharia banking to agricultural businesses and the nature of farmers  who  tend  to  be  difficult  to  accept  changes.24

Furthermore, there are at least three characteristics inherent in agricultural credit schemes that have the potential to cause ineffectiveness,  including:

1.  Loans  are  always  based  on  fixed  interest.  If  farmers fail in their farming business, either because of crop failure or low market prices, they will not be able to repay the loan so they can get into a bigger debt because of the interest-bearing principle.

2. here is a gap in the business space between borrowers (debtors) and lenders (creditors).

The debtor is purely working in the real sector, while the creditor is only engaged in the monetary sector. As a consequence, business risk will generally only be borne by the debtor, while the creditor will still benefit  at the interest rate that is set.

3.  The  agricultural  financing  system  has  been  integrated with non-agricultural financing.

The business calculation system in the non- agricultural sector, especially industry and services, if applied to agricultural businesses tends to overestimate. If forced, this will prevent agricultural businesses from receiving

credit support in the amount needed.25 Islamic banking financing has been seen in the  Islamic  financial system  in Indonesia  which is  still  in the growth stage (infant industry) which still has many weaknesses in various ways, including:

operational weaknesses, such as the low level of equity-based  financing,  such  as mudharabah and musyarakah, and the dominance of debt-based financing, such as murabahah (buying and selling), which makes Islamic banking similar in nature to conventional banking.

Based on the above discussion, it can be said that the contribution of Islamic banking financing  can increase the disparity of people’s income, this is because Islamic bank financing is still dominated  by financing in the form of consumptive financing  rather  than  financing  in  the  form  of  productive. 

However, if it is seen that the public’s interest in conducting transactions or financing Islamic banks  is still very minimal.

The following data shows how big the contribution of Islamic banks in community activities is:

GRAPHIC

Based on the graph, it can be seen that people do more transactions with conventional banks than Islamic banks. This proves that Islamic  bank  financing  can  increase  the  disparity  of people’s income, apart from the fact that Islamic bank financing is more dominated by murabahah contracts that are engaged in the consumptive sector, the contribution of Islamic banks  in  transaction  activities  or  public  financing 

25 Ashari Dan Saptana, Prospek Pembiayaan, p. 133

(13)

is still less than transactions in conventional banks. In Islamic banks, there are three types of institutions, including Islamic Commercial Banks which contributed 64.62% and Sharia Business Units contributed 32.86% and Islamic People’s Financing Banks contributed 2.52%.

The  results  of  this  study  are  different  from  the results of research conducted by Purwanto (2017), where financing carried out by Islamic commercial banks and sharia business units has a significant positive effect on community income  disparities  because  the  distribution  of  financing  carried out by Islamic banks is dominated by the consumptive  sector.  While  the  financing  carried  out by  Islamic  people’s  financing banks  does  not  affect  the  disparity,  but  it  does  not  rule  out  the  possibility that the financing carried out by Islamic  people’s  financing  banks  can  also  increase  the  disparity of people’s income.

Conclusion

Financing carried out by Islamic Commercial Banks and Sharia Business Units as well as financing carried out by Islamic People’s Financing  Banks in Indonesia from 2014 to 2018 contributed positively to the disparity of people’s income.

Based on the results of financing data processing  carried out by Islamic Commercial Banks and Sharia Business  Units,  it  has  a  significant  positive  effect  on the level of community income disparity with a  probability  value  of  0.0227  <0.05.  Meanwhile,  the  financing  carried  out  by  the  Islamic  People’s  Financing  Bank  also  has  a  positive  effect  on  the  level of income disparity in the community with a probability value of 0.0193 <0.05. The cause of the  increasing disparity in people’s incomes is due to the  distribution  of  financing  which  is  dominated  by the consumptive sector such as financing with  murabahah contracts, rather than other financing  based  on  profit  sharing.  In  Islamic  commercial  banks  and  sharia  business  units,  financing  with  murabahah contracts from 2014 to 2018 will be totaled Rp. 6,573,270,000 and in Islamic people financing  banks  it  is  worth  Rp.  26,356,152,000.

However, if it looks at the Gini ratio from 2014 to 2018, it has decreased gradually, this is because the government, in this case the Ministry of Agriculture, is trying to improve people’s welfare

through various mechanization programs and massive  infrastructure  development.  This  effort  is made to reduce the number of poor people and reduce income inequality. The population living in rural areas reaches 60%, where most of them are farmers with 70% of their main income coming from the agricultural sector. Meanwhile, the  role  of  sharia  banking  in  terms  of  financing  for agribusiness businesses is still very minimal compared to other businesses, so a strategy is needed to increase the role of sharia banking for agribusiness businesses.
