Dalam DEA terdapat metode non parametrik yang terbagi dalam dua bagian yaitu Constant return to scale (CRS) dan Variable Return to Scale (VRS). Model CRS mengasusmsikan bahwa rasio antara penambahan input dan output adalah sama. Artinya, jika ada tambahan input sebesar x kali,maka output akan meningkat sebesar x kali juga. Asumsi lain yang digunakan dalam model ini adalah bahwa setiap perusahaan atau unit pembuat keputusan (UPK) beroperasi pada skala yang optimal. Rumus dari Constant return to scale dapat dituliskan sebagai berikut:

Technical Efficiency of Pesticide Application on Tomato, Chinese Cabbage and Cauliflower in Simpang Empat Sub-District Karo Regency

Technical Efficiency of Pesticide Application on Tomato, Chinese Cabbage and Cauliflower in Simpang Empat Sub-District Karo Regency

Table 4 shows that the efficiency of pesticide usage using the assumption of Constant Return to Scale (CRS) is 0.115. The technical efficiency value shows that the average sample can reach 11.5% and the value ≤ 1, which means that the use of pesticide input is inefficient from technical point of view. The analysis shows that 34 farmers (97.15%) are technically inefficient in return for Scale (CRS) and only 1 farmer (2.85%) is technically efficient in the use of pesticides in cauliflower. While using the assumption of Variable Return to Scale (VRS) obtained the average value of technical efficiency of 0.377 that the average sample can reach 3.77%. The average efficiency of pesticide use using VRS assumption is 0.377 ≤ 1, which means that the use of pesticide input on the flower crop is not efficient from a technical point of view. The calculation of analysis with Variable Return to Scale (VRS) resulted in 30 farmers (85.27%) found inefficient and only 5 farmers (14.28%) were technically efficient. From the results obtained samples (flower farmers) that are efficient use of pesticides technically are respondent or DMU 8,11,15,25 and 29 with value of 1,000. So, it can be concluded that only one farmer (2, 85%) efficient by CRS and five farmers (14, 28%) efficient by VRS. This implies that a large number of respondent farmers face serious problems in terms of technical efficiency.

EFISIENSI TEKNIK PERBANKAN INDONESIA PASCAKRISIS EKONOMI: SEBUAH STUDI EMPIRIS PENERAPAN MODEL DEA

Hasil Perhitungan Efisiensi Perbankan dengan Metode Constant Return to Scale Hasil analisis dengan metode constant return to scale menunjukkan bahwa pada tahun 2000 bank yang memiliki efisiensi paling kecil adalah Bank Pembangunan Daerah DKI atau yang lebih dikenal dengan bank DKI yaitu sebesar 12,86 persen (lihat tabel 3). Sementara bank yang sudah mencapai efisiensi 100 persen ada 5 bank yaitu Bank Rakyat Indonesia (BRI), bank mandiri, BCA, bank danamon dan bank jabar. Inefisiensi bank DKI ini disebabkan oleh alokasi input yang kurang maksimal untuk memperoleh output. Variabel yang belum dialokasikan maksimal adalah aktiva yang masih menca- pai 7,3 persen dan harus ditingkatkan peng- gunaan inputnya sebesar 92,7 persen. Pada aktiva ini terjadi pemborosan aset karena target efisiensi seharusnya 4.542.969.9 ribu namun dialokasikan sebesar 62159479.0 ribu. Penggunaan tenaga kerja juga demi- kian.

Directory UMM :Data Elmu:jurnal:E:Ecological Economics:Vol32.Issue2.Feb2000:

Ecological scientists have engaged ecological problems at enormous levels (e.g. greenhouse gases, regional and global biodiversity) and broad ranges over the past two decades (Allen and Starr, 1982; Addicott et al., 1987; Meentemeyer and Box, 1987), and the need to consider the issues regarding scales and scaling in ecological analyses is increasingly important (see, for example, Steele, 1978; Risser and Mankin, 1986; Steele, 1989; Powell and Steele, 1995). Consequently, ecologists continue their active search for guiding principles that would allow them to combine data and mod- els at different spatial and temporal scales, and to extrapolate information between scales and levels (Turner et al., 1989a; Costanza et al., 1997). De- spite the goal of finding interscale models, many scientists working in areas such as physiological ecology (Jarvis and McNaughton, 1986), popula- tion interactions (Addicott et al., 1987), soil pro- cesses (Sollins et al., 1983), vegetation analysis (Getis and Franklin, 1987), aquatic ecology (Steele, 1985), paleoecology (Solomon et al., 1980), and landscape ecology (Meentemeyer and Box, 1987) realize that their predictions are scale and level dependent and that a single mechanism rarely explains patterns found at different levels (Turner et al., 1989a; Menge and Olson, 1990; Wessman, 1992; Gueron and Levin, 1995).

Taking Moneyless Exchange to Scale Measu (2)

The  primary purpose of a  credit clearing  system is to facili‐ tate  the  exchange  of  goods  and  services  among  its  users  without  the  use  of  political  money or  the  need  to  borrow  money from  a  bank. It  is  an  arrangement  that  enables “re‐ ciprocal  exchange,”  i.e., in  which  each  participant  gives  as  much  value  as  s/he  gets,  and  gets  as much  value  as  s/he  gives  (in  real  goods  and  services).  Commercial  trade  ex‐ changes  (sometimes  called  “barter”  exchanges)  and  grass‐ roots  community  exchange  systems,  like  LETS,  are  exam‐ ples of entities that utilize this credit clearing process.  In order to determine the health and effectiveness of such a  system,  it  is necessary to have  some  indicator(s)  that tells  how well  it  is achieving  that  objective  and  how  likely  it  is  that the system will  be sustainable, as well as scalable. Con‐ trol  mechanisms  must  also  be  in  place  to  assure  that  ad‐ ministrative  policies  established  by  the  membership  are  being  carried  out  and the  principle  of reciprocity  is  being  upheld.

Career Persistence Model for Female Engineers in the Indonesian Context

Career Persistence Model for Female Engineers in the Indonesian Context

For example, in the US, women make up 20% of engineering graduates, but it is estimated 40% quit or never enter the engineering profession (Silbey, S. 2016). In Indonesia women only represents 5% of engineers (Sakernas BPS, 2015), making the field is still dominated by male engineers; and place woman as minority*. Although various research have proven more diverse leadership leads to increased performance, but in reality, the so-called ‘leaky pipeline’ phenomenon for female engineers is also prevalent in Indonesia, especially as the further a woman advances in her career peran perempuan di dalam keluarga, masyarakat dan tempat kerja, serta mempelajari bagaimana insinyur perempuan yang telah berhasil menavigasi hambatan negatif dalam berkarir untuk tidak keluar dari jalur profesi insinyur. Bertentangan dengan hasil temuan riset sebelumnya, riset empiris ini menunjukkan bahwa insinyur perempuan merasa diperlakukan setara dengan rekan kerja laki-laki di tempat mereka bekerja, walaupun ada beberapa tuntutan pekerjaan yang dapat menjadi penghalang. Pengakuan kuat akan peran seseorang di dalam masyarakat kolektif melampaui pendapat yang menurut hukum Islam (fiqh) perempuan telah terpinggirkan, mengalami ketidakadilan dan diskriminasi. Studi serupa dimasa mendatang perlu mempelajari aspek dukungan sosial di tempat kerja guna mendapatkan solusi yang dapat mempertahankan dan meningkatkan andil perempuan dalam profesi insinyur di Indonesia.
