Analisis Efisiensi Teknis dan Faktor Penentunya pada Usahatani Kentang (Solanumtuberosum L.) di Kota Pagar Alam, Provinsi Sumatera Selatan

Abstract

This study aims to determine and analyse the level of technical efficiency and the factors influencing technical efficiency of a potato farming in North Dempo, sub-district Pagar Alam City, South Sumatera Province using 51 farmers who are censused. Frontier production function, estimated using the MLE method, is used to determine the level of technical efficiency. Meanwhile, multiple regression estimated using OLS approach is used to determine factors influencing technical efficiency level. The research showed that, land area, seed, organic fertilizer, ZA fertilizer, Ponska fertilizer, and fungiside were significantly affect potato production. The research finds that the level of technical efficiency of potato farming was, on the average, 81.336 percent. The research also shows that the intensity of ex-tension and farmers' experience affect significantly and negatively technical inefficiency while formal education, age, and land ownership status do not.

Technical Efficiency and Income Level of Sugarcane Farming in Pati Regency

“…The family heads of sugarcane farmers in Pati Regency were mostly categorized in productive age, about 90% of the entire respondents. This condition is consistent with the research of Maryanto et al (2018), which stated that farmers in productive age are more efficient because they conceive higher capability in performing adaptation and innovation. Therefore, they are more capable of preventing stagnation or a tendency of decreasing productivity due to the degradation of resources.…”

“…Meanwhile, the regression coefficient of the cultivation area for the ratooning system is 0.997, which means that every 1% addition of area width for ratoon cane will increase 99.7% of ratoon cane production. This result is similar to the research of Badmus and Ariyo (2011), Arta et al (2014), Gultom et al (2014), and Maryanto et al (2018), which stated that the improvement of the cultivated area as production input would cause improvement of production. This is because the input utilization will be more efficient if the cultivated area that owned is expanding.…”

“…The extension is held once a month and will be more intensive nearing the harvesting season. The experience and extension participation can influence the capability of farmers in decision making to implement new technology on their farms because it can improve individual knowledge, skills, and proficiency (Maryanto et al 2018).…”

“…Some issues also occur in the effort of productivity improvement, including the utilization of production inputs (fertilizer, seed, pesticide, and labor), which not following the recommendation. The improper amount and combination of those production factors have affected the production and the spent cost (Maryanto et al 2018). If this condition keeps continuing, then the low level of production and the high cost will cause the income level and the wellbeing of farmers to decrease.…”

“…According to the review, the approach suitable to estimate the technical efficiency and inefficiency rate in Pati Regency is the application of a stochastic frontier production function. This model has been widely used to study the technical efficiency of farming, including onion farming (Waryanto et al 2014), cassava farming (Anggraini et al 2016), potato farming (Maryanto et al 2018), and sugarcane farming (Purnamasari and Ar 2018). Discussing further, the studies regarding technical efficiency mostly used the Cobb-Douglas production function.…”
