Non-Parametric Approach towards Smallholders Rubber Production Efficiency: A Two-Stage Data Envelopment Analysis (DEA)

Abstract

the productivity of smallholders' rubber is lower than the productivity of private and government estates. The productivity of Indonesian smallholders' rubber can be enhanced through intensification or technology improvement. The main objective of this study is to estimate the technical efficiency level and technical inefficiency effect model of smallholder's rubber in South Sumatra. A survey was conducted from November 2016 to March 2017 in 11 districts in the South Sumatra Province. 384 rubber farmers were selected using a combination of purposive, multi-stage and random sampling techniques. This study employed a nonparametric approach (Two-stage DEA) using cross-sectional data to understand the rubber production process. The findings showed that the mean technical efficiency of the sampled farms under the VRS DEA was estimated at 0.80. However, the mean technical efficiency was still less than 0.82, indicating that on average, the sampled farms were not technically efficient. Tobit regression results showed that all of the determinants have the expected signs (negative) in relation to technical inefficiency, thus implying that these factors increase technical efficiency as expected. However, only two of the determinants, farming experience and tapping system were statistically significant to the level of technical efficiency.Contribution/ Originality: Low productivity has been a primary issue for Indonesian smallholders' rubber.The best effort to improve rubber productivity is by managing resources more efficiently. This paper contributes to the study production efficiency of smallholders' rubber in Indonesia by employing the two-stage DEA analysis.

Pengukuran Efisiensi Perusahaan Go-Public Sektor Pertanian dan Perkebunan di Indonesia dengan Metode Data Envelopment Analysis (DEA) Bootstrap

“…Penentuan perusahaan yang tepat untuk berinvestasi adalah perusahaan yang memiliki efisiensi dalam penggunaan sumberdaya (input) untuk menghasilkan produk (output) secara optimal. Menurut Cooper et al dalam Syarifa et al (2023) efisiensi merupakan indikator penting dalam mengukur kinerja aktivitas operasional pada sebuah perusahaan. Efisiensi digunakan untuk menilai apakah perusahaan sudah berproduksi dengan biaya minimum dan menghasilkan output maksimum atau belum.…”

Factors Affecting the Economic Efficiency of Small-Scale Rubber Plantations: With Special Reference to Kalutara District in Sri Lanka

“…A substantial volume of literature has used yield or productivity of small-scale rubber growers as the dependent variable together with Cobb-Douglas production function for measuring TE (bin Sepien & Etherington, 1980;Hadi & Budhi, 1997;Waduge et al, 2015;Aliyu et al, 2017;Wijesuriya et al, 2007;Syarifa et al, 2019). The Cobb-Douglas production function was selected to be the most suitable functional form based on log-likelihood ratio test (LR test).…”

Analisis Efisiensi Rantai Pasok Lateks dengan Metode Data Envelopment Analysis (DEA) di PT Perkebunan Nusantara IX Kebun Krumput Banyumas

“…Efisiensi diukur dalam bentuk perubahan proporsional dalam input atau output sehingga mampu menilai kinerja mana yang efisien (Coeli, et al dalam Abidin dan Endri, 2009). Menurut Farrel, et al dalam Syarifa et al (2020), pemodelan DEA awal mulanya dikembangkan oleh Charnes, Chooper dan Rhodes pada tahun 1978. Model yang sering digunakan yaitu DEA Model CCR yaitu hubungan linier yang dihasilkan setelah analisis antara input dan output sesuai dengan orientasinya.…”

“…Asumsi lain yang digunakan dalam model ini adalah bahwa setiap perusahaan atau DMU beroperasi pada skala yang optimal. Model CCR menjadi model yang paling sering digunakan karena lebih sederhana dengan beranggapan input yang dimasukan adalah konstan (Coeli et al dalam Syarifa et al, 2020). Menurut Coeli, et al dalam Muttaqien et al (2022) skala hasil produksi (return to scale) merupakan perubahan skala output hasil produksi akibat dari penggandaan input atau faktor produksi yang digunakan.…”
