ANALISIS EFISIENSI ALOKATIF DAN RASIONALITAS KEPUTUSAN PETANI BAWANG DAUN DI KECAMATAN KEPUNG, KABUPATEN KEDIRI

Scallion (Allium fistulosum L.) is a leading horticultural commodity with high market potential, with Kepung District serving as the largest production center in Kediri Regency. However, the low productivity of scallion farming in Kepung District is suspected to be related to inefficient input use and farmers' decisions based on habits and experience. This study aims to identify the production function stage, analyze allocative efficiency, and describe the rationality of farmers' decisions. The respondents consisted of 36 scallion farmers using a quantitative descriptive method with a survey approach. Data were analyzed using the Cobb-Douglas production function and allocative efficiency analysis by comparing the Marginal Product Value (MPV) and input prices (Px). The production function estimation results showed that collectively all inputs significantly affected production, with seeds and pesticides having a partial significant effect. Based on the summation of regression coefficients, scallion farming was in the condition of Increasing Return to Scale (IRTS) with an RTS value of 1.411 > 1. The allocative efficiency analysis revealed that the MPV/Px values for land area), labor, seeds, and pesticideswere > 1, indicating that the use of these four inputs remained insufficient, while the MPV/Px value for fertilizer (-0.06) was < 1, indicating that fertilizer use had exceeded the optimal limit. Farmers' decisions in allocating production factors were not entirely rational as they were still based on the empirical belief that more inputs would lead to higher yields, without considering the principle of the law of diminishing return..
