Abstract

Malaka Regency as an agricultural area does not yet have good irrigation asset maintenance management as a supporter of success in the agricultural sector. The obstacle faced in dealing with damage to irrigation assets is the difficulty in determining maintenance priorities due to the government's limited budget. It causes maintenance activities to be carried out in the stage. This study aimed to assess the physical condition of assets, asset functioning, service areas, maintenance costs, and maintenance priorities. The handling solution is carried out by developing a strategy for developing the Weliman irrigation area using a SWOT analysis. In the research results, the irrigation assets prioritized for maintenance are right secondary channel 1, left primary channel 5, distribution structure 3, left primary channel 3, left primary channel 4, distribution structure 4, primary channel left 2, and distribution structure 2. The results of the SWOT analysis, the recommended strategy is the Growth strategy, namely, maximizing the strengths owned to take advantage of existing opportunities.

1. Introduction

An irrigation system is a unit that is structured based on efforts to provide, share, manage, and regulate water to increase agricultural production for this reason, efforts are needed for the preservation of irrigation facilities and their existing assets [1]. Improving the performance of irrigation systems mainly depends on how appropriately the available resources are used in crop production [2]. In addition, irrigation system performance is influenced by water use efficiency on the land, asset conditions, and labor requirements for operation [3].

Regulation of the Minister of Public Works Number 23 of 2015 [4] concerning the Management of Irrigation Assets stipulates that to manage irrigation networks effectively, efficiently, and sustainably, it is necessary to manage irrigation assets. According to Zamroni [5], realizing the irrigation system's sustainability is achieved by developing and managing irrigation systems.

Several things must be assessed to address the sustainability of irrigation services, including the economic value of infrastructure over time, the need for re-investment, and the long-term impact of re-investment policies [6]. Management and development of irrigation systems require good infrastructure. Management and development of irrigation systems can be realized by managing assets to maintain the conditions and functions of irrigation networks. Irrigation asset management can be realized by implementing asset management. Asset management is carried out to maintain the function of irrigation networks [7].

Bere, Harisuseno, Prayogo: The Effect Of Damage To Irrigation Assets On The Management Of The Irrigation Network

The Weliman Irrigation Area with a total service area of 1000 ha has experienced a decrease in productivity. Data obtained from the Malaka District Agriculture Service resulted in average agricultural productivity in 2019 of 5 tons/ha, while in 2020 the average agricultural yield decreased to 3.7 tons/ha. One of the reasons for this decline in productivity was the condition of many damaged irrigation assets. Based on a survey conducted by the PUPR Office of East Nusa Tenggara Province, only some of the irrigation assets were in good condition, and the rest were in damaged condition.

The poor condition of irrigation assets causes the consistency of water distribution to be not maintained, resulting in water being unable to rinse the entire planned area. In addition, more and more irrigation assets are damaged, increasing the need for maintenance costs.

In reality, requests for funds for the management of irrigation networks from year to year cannot always be met according to needs. In determining the budget allocation for irrigation networks, there are many influencing factors besides technical factors; policy, political, and local economic capabilities in financing an activity [8]. Therefore PUPR Regulation number 13/PRT/M/2012 [9]

mandates the type of treatment and priority for repairs based on data on the physical condition of irrigation networks, functions of irrigation networks, service area of irrigation areas, and maintenance costs from the irrigation network.

Therefore it is necessary to evaluate the conditions and functions of irrigation assets to determine conditions and determine maintenance priorities according to the size of the service area and the size of the budget required. A SWOT analysis determines the right irrigation asset management strategy according to the situation and conditions at the research location. SWOT analysis is carried out based on four main factors, namely: strength factors, weakness factors, opportunity factors, and threat factors, with each variable being ranked with the same weight based on a questionnaire distributed to stakeholders. From the emergence of these problems, it is hoped that an effective development strategy in managing irrigation networks with limited budget estimates will be obtained to produce maintenance and rehabilitation activities per the available budget allocation.

2. Research Methods

2.1. Research Sites

The Weliman Irrigation Area has a service area of 906 ha covering Haitimuk Village, Kleseleon Village, Motaulun Village, Naas Village, Maktihan Village, and Rabasa Village. The distance of the Weliman Irrigation area from Betun, the capital of Malaka Regency is 13 km.

2.2. Research Method and Research Variable

The research method used in this research is qualitative. The study was conducted based on empirical data according to conditions in the field [10]. The research was carried out by the process of generating data from the findings in the form of direct observation and interviews with respondents.

The research variables used in this study are as follows: condition and function of assets, damage to irrigation assets, need for maintenance costs, setting priorities for irrigation maintenance, and strategies for managing irrigation assets.

2.3. Assessment of Condition and Function of Irrigation Assets

The condition and function of irrigation assets are assessed to determine the type and volume of damage to irrigation assets. In addition, conditions and functions are assessed to measure the success of irrigation network maintenance activities [11]. The condition level of irrigation assets and the percentage level of condition of irrigation assets can be seen in Table 1.

Table 1. Percentage of damage to irrigation assets [10]

Condition Damage Index Handling

Well <10% Routine Maintenance

Light Damage 10-20% Periodic Maintenance

Moderate Damage 20-40% Repair

Heavily Damaged >40% Replacement

The level of function of irrigation assets and the percentage level of function of irrigation assets can be seen in Table 2.

Table 2. Percentage of damage to irrigation assets [10]

Damage Level Classification Handling

>90% Well Routine Maintenance

70% – 90% less functional Periodic Maintenance

55% - 69% Bad Repair

<55% Does not work Replacement 2.4. Estimated Maintenance Cost

In determining the budget plan, the components observed include the volume of damage, the volume of work, and the unit price used as a standard for calculating the budget plan [12]. In planning the calculation of the budget for repairs, the steps are carried out as follows: calculate the volume of each work according to the volume of damage, and determine the analysis of the unit price of work obtained from the unit price of materials and wages. Maintenance budget planning can be calculated with the following equation [12]:

Work Price = unit price x Work volume (1) Where work price (Rp), unit price (Rp), and work volume (m³).

2.5. Priority for Maintenance of Irrigation Assets

Repair priorities are based on data: the area of irrigation areas (Adi), the area of service affected by damage to irrigation assets (Aas), the physical condition of irrigation networks, and the physical functions of irrigation networks. Criteria for the condition of physical infrastructure are carried out

(4)

79

by direct survey with the level of damage classified based on the condition of the assets [13]. Priority scale determination can be calculated using the following equation [9] :

𝑃 = (𝐾 ∙ 0.35 + 𝐹^1.5∙ 0.65) ∙ (^𝐴^𝑎𝑠

𝐴_𝑑𝑖)^−0.5 (2)

Where p is the priority, K is the condition score (%), F is the function score (%), Aas is the service area affected by asset damage (ha), and Adi is the irrigation area (ha).

2.6. SWOT Analysis

The stages in the SWOT analysis are as follows [14].:

a. Define variables

In determining the variables used in the SWOT analysis, it is based on indicators related to the performance of the irrigation system and the management of irrigation assets, namely: the condition of physical infrastructure, crop productivity, operation, and maintenance support facilities, personnel organizations, documentation, and associations of water using farmers (HIPPA).

b. Questionnaire distribution

In determining the significance level and rating an assessment was made based on the results of the questionnaires distributed and filled in by the respondents. Respondents who were interviewed totaled 20 people, including the Head of the Field and the Water Resources Technical Staff of Malaka Regency, Sluice Officers, Irrigation Observers, Irrigators, and Farmers.

c. Analyze SWOT strategic factors

Developing an asset management strategy analyzes strategic factors, which are the compatibility between external opportunities and internal strengths while considering external threats and weaknesses. This analysis is based on the assumption that an effective strategy is derived from a good "fit" between internal resources (strengths and weaknesses) and the external situation (opportunities and threats) [15]. The SWOT analysis process is as follows: give weight to each variable on each factor based on the level of influence, each variable in each factor is given a ranking, do the weighting or multiplication between the weights and rankings to obtain a total score on each factor, calculating the coordinates of the swot diagram to find out the quadrants of each factor so that conclusions can be drawn about which strategy gets implementation priority to maximize development.

3. Results and Discussion

3.1. Assessment of the Existing Condition of Weliman Irrigation Assets

Existing condition assessment is carried out using visual observation and continued with measurements to obtain the extent of existing damage. The assets assessed include primary canals with a length of 3866.4, secondary canals with a length of 672 m, five buildings, and 12 floodgates.

Existing condition assessment includes:

1) The physical condition of the irrigation channel

Structural damage conditions in the Weliman Irrigation Area include damage to the carrier channel, namely: Cracks in the Channel wall and floor of the irrigation Channel resulting in seepage, peeling plaster on the Channel walls and irrigation Channel floor, perforated Channel walls, collapsed Channel walls resulting in water seepage which causes water supply reduced and vegetation that interferes with the smooth flow of water. The assessment results can be seen in Figure 2 and Figure 3.

Figure 2, the primary channel has a total length of 3866.4 m, of which 3344.59 (86.5%) are in good condition while those in damaged condition are 521.81 m (13.5%). Figure 3 shows the total length of the secondary channel of 672 m with a total of 119.15 m (17.7%) of damaged channels, while 552.85 m (82.3%) of the channels are in good condition. Therefore, damage to the primary canal with a length of 521.81 m is classified as severely damaged and must be addressed immediately.

3) The physical condition of the building above the channel

The physical condition of the structure above the channel is still in good condition. The results of the physical condition assessment of the Weliman irrigation assets can be seen in the recapitulation results in Figure 5.

An example of an assessment is as follows: On Weliman Left 4 Section (R.W.Ki.4), it is known that each type of damage to the primary canal includes 11.60 m (5%) cracks, 0.99 m (5%) chipped plaster, 2.84 m2 perforated (20%) and collapsed 3.39 m (40%). The total percentage of structural damage is 70%. Based on Table 1, the percentage > 40% is classified as heavily damaged. So the condition value for R.W.Ki.4 is 1 with the damage being categorized as heavily damaged.

Figure 5. Recapitulation of asset condition assessment

Figure 5 shows the results of the assessment of the physical condition of the assets of the Weliman Irrigation Area can be concluded that the irrigation infrastructure that needs to be maintained is:

Weliman 1 secondary channel, Weliman Primary 1, Weliman Primary 2, Weliman Primary 3, Weliman Primary 4, Weliman Primary 5, distribution structure 1, distribution structure 2, distribution structure 3, distribution structure 4, distribution structure 5.

3.2. Asset performance assessment

The functioning condition of assets is closely related to the physical condition of assets. Therefore, the good physical condition of the assets also results in the good functioning of the irrigation network.

The recapitulation of the results of assessing the functioning of assets can be seen in Figure 6. Figure 6 shows the results of the assessment of the functioning of Weliman irrigation assets that need to be maintained are Secondary Weliman 1, Primary Weliman 2, Primary Weliman 3, Primary Weliman 4, Primary Weliman 5, distribution structure 1, distribution structure 2, distribution structure 3, distribution structure 4, distribution structure 5.

In carrying out cost analysis calculations, it is necessary to price materials and wages. Therefore, the price of materials and wages will be used as a reference for calculating the unit price of work for implementing maintenance activities for Weliman irrigation assets, Malaka Regency. Maintaining irrigation assets in the Weliman irrigation area includes sluice gates and structures. Calculation of the analysis of the unit price of the work, the volume of work, and the recapitulation of the budget estimate plan (RAB) for the rehabilitation work can be seen in Table 3.

3.4. Priority for maintenance of irrigation assets

Maintenance priority is determined based on data on the area of service affected by asset damage, the physical condition, and the function of the asset. The results of calculating the priority value and ranking of asset maintenance can be seen in Figure 7.

Figure 7. Priority for maintenance of irrigation assets

Figure 7, the infrastructure with the lowest score is the main priority for irrigation maintenance, namely the left primary channel 5 and the right secondary channel. The second to fifth priority in a row is the left primary channel 3, the distribution structure 3, the primary channel 4, the distribution structure 5, the distribution structure 4, the primary channel 2, and the distribution structure 2.

3.5. SWOT Analysis

The initial step in the process of developing an asset management strategy is to analyze the strategic factors which are the compatibility between external opportunities and internal strengths as well as paying attention to external threats and internal weaknesses. Developing the strategies needed is to combine strength, weakness, opportunity, and treatment factors into one matrix in which all aspects of SWOT are identified, then from the quadrant where the SWOT meets. Strategies are made called the SWOT matrix.

The results of the SWOT matrix obtained a strategy that can be used as the right strategy for developing irrigation assets in the Weliman Irrigation Area.

3.5.2. Compile Internal – External matrix

Identification of internal and external factors creates four main strategies, namely: SO strategy (strengths and opportunities), WO strategy (weaknesses and opportunities), and ST strategy (strengths and threats). After the External Factors and Internal Factors are compiled, the S + O, W + O, S + T, and W + T scores can be added up, as shown in Table 6.

Table 6. SWOT analysis weighting results S = 3.65 W = 3.55

O = 4.00 SO = 7.65 WO = 7.55 T = 3.77 ST = 7.42 WT = 7.31

Table 6 shows that strategic priorities are arranged based on the combination of strategies with the highest to the lowest value. More details can be seen in Table 7.

Table 7. SWOT analysis strategies alternatives

III Strength - Threat(ST) 7.42

IV Weakness - Threat(WT) 7.31

(11)

86

The alternative strategy that gets the highest weight is strength-opportunity (SO), meaning that the SO strategy uses strength to take advantage of existing opportunities. This condition is very advantageous because, in terms of internal factors, strength factors have a greater value than weaknesses. In contrast, in terms of external factors, the opportunities are far greater than the threats in maintaining irrigation assets.

The results of the SWOT matrix obtained an alternative strategy, namely the S-O (Strength - Opportunity) strategy which can be used in efforts to develop irrigation asset management in the Weliman Irrigation Area as follows:

Strategy S-O (Strength - Opportunity)

Strategies that use strength to take advantage of existing opportunities with a choice of strategies as follows: i) Maximizing operation and maintenance activities to improve conditions and functions of irrigation assets with financial assistance from the government while maximizing community-based work-intensive programs by empowering HIPPA: ii) Increase planting productivity by optimizing the function of the intake, iii) Carry out an inventory of data using an android based irrigation asset management application to obtain data on the condition and function of irrigation assets as well as the geospatial map layout of the Weliman irrigation area, iv) Maximizing the annual irrigation operation and maintenance consultancy meetings to increase understanding of operation and maintenance while maintaining cooperative relations between Provincial Governments and Local Governments, v) Maximizing the provision of water to meet water needs to suit the proposed cropping pattern.

3.5.3. Define SWOT diagrams

In determining the coordinates of each factor, calculations are carried out using the IFAS and EFAS matrices to obtain the value of the difference between the total value of strengths minus the total value of weaknesses and the total value of opportunities minus the total value of threats.

Furthermore, the results of the difference between the IFAS and EFAS factors are plotted in the SWOT diagram to obtain the chosen strategy [17]. The results of the calculations can be seen in Table 8.

The total value of strength minus the total value of weakness is 0.11, and the result of calculating the value of opportunity minus the total value of threat is 0.23 to obtain a SWOT coordinate of 0.11:0.23. Then plotted into a SWOT diagram to get the selected strategy. The SWOT diagram can be seen in Figure 8.

Based on the results of the SWOT diagram where the coordinates are (0.11: 0.23), it can be seen that the position of the point is in quadrant I, namely growth, meaning that the situation is very profitable because it has opportunities and strengths so that it can maximize strengths by taking advantage of opportunities which exists.
