Dampak Penggunaan Combine Harvester terhadap Kehilangan Hasil Panen Padi di Provinsi Banten

Abstract


English
Combined Harvester (CH) aid is part of the Indonesian government policy instrument for accelerating rice production and increasing farmers’ income. In addition to reducing harvesting cost and time, CH may also reduce harvest loss. This study intends to quantify rice yield loss reduction if CH is used for harvesting. The study was conducted in Banten Province in 2014 using primary data collected from 119 CH user farmers and 116 non-user farmers selected purposively. Preliminary analysis was conducted using regression which was estimated with the Ordinary Least Square (OLS) method. Since OLS estimated regression is prone to sample selection bias, subsequent analysis is conducted using the Propensity Score Matching (PSM) estimator with a logistic regression. The PSM analysis support the regression analysis that CH reduces harvest loss. Based on the Stratification Matching, it was found that the CH reduces harvest loss by up to 200.39 kg per hectare or around 3.52% of total yield. It is recommended that the Government facilitates provision of technical assistance and training for CH operator farmers or farmers’ groups particularly the first users aid recipients. The harvest reduction advantage is an additional reason for supporting feasibility of CH scaling out policy in Indonesia.


Indonesian
Bantuan combined harvester (CH) padi adalah salah satu instrumen kebijakan pemerintah Indonesia untuk mendorong peningkatan produksi dan pendapatan petani padi. Walau manfaat utamanya adalah untuk menghemat ongkos dan mempercepat panen, CH juga dapat mengurangi kehilangan panen. Penelitian ini bertujuan untuk menghitung kuantitas pengurangan kehilangan hasil usaha tani padi jika panen dilakukan dengan CH. Penelitian dilakukan menggunakan data primer dari 119 petani pengguna dan 116 petani nonpengguna CH yang dipilih sengaja di Provinsi Banten pada tahun 2014. Analisis awal dilakukan dengan regresi yang diduga dengan kwadrat terkecil biasa (OLS). Untuk mengatasi potensi bias sampel pada analisis regresi OLS, selanjutnya digunakan penduga Propensity Score Matching (PSM) dengan mempergunakan regresi logistik. Hasil analisis PSM memverifikasi efek positif penggunaan CH terhadap kehilangan hasil berdasarkan analisis regresi OLS. Berdasarkan Stratification Matching didapatkan bahwa penggunan CH dapat menekan kehilangan hasil sebesar 200,39 kg per hektare atau sekitar 3,52% dari total hasil. Disarankan agar pemerintah memfasilitasi pendampingan dan pelatihan teknis kepada petani atau kelompok tani operator, utamanya pengguna pertama penerima bantuan. Manfaat mengurangi kehilangan panen memperkuat kelayakan kebijakan perluasan penggunaan CH di Indonesia.
