Technical Efficiency of Small-scale Intensive Shrimp Farming in East Java, Indonesia: A Non-parametric Analysis

The aim of this study was to investigate the level of technical efficiency in small-scale intensive shrimp farming. Data collected from 125 small-scale shrimp farmers in East Java Province, Indonesia. The levels of technical efficiency calculated using input oriented Data Envelopment Analysis (DEA). The results revealed that shrimp farmers in the study area were technically inefficient. Technical efficiencies vary among shrimp farms, ranging from 0.62 to 1.00.

Small-scale shrimp farmers have contributed significantly to the increasing of shrimp production in Indonesia. In line with increasing production, they have also faced with various risks, thus resulting in high fluctuation of their income. Risk management strategies are needed to cope the risks and to increase their sustainability in shrimp farming. The research analyzed the various factors of risks and possibilities ex-ante and ex-post coping strategies for small-scale shrimp farmers in Indonesia. A field survey of 166 shrimp farmers was conducted in the North and South coastal zone of East Java, Indonesia. The result revealed that the cluster of production risks was the main risk in shrimp farming, following by clusters of price risk, financial risk, personal risk, and institutional risk. The top three important factors of risk that influenced in shrimp farming were high mortality due to shrimp diseases, price shrimp volatility, and lack of capital to operate shrimp farm. Related with ex-ante on-farms strategies, following better management practices, use shrimp fries from certificated producers, and strictly in feeding management is the best strategies. Furthermore, subsidy or incentives to influence production practices at the farm level and sharing the risks through insurance, contract for input and output are possibilities strategies for government support and risk sharing, respectively. In ex-post strategies, generating alternative income activities, communities or informal insurance, and adjustment of labor use are the kinds of on-farms strategies. Moreover, the government supports in ex-post strategies is a loan with flexible repayment schedules

Coping up with the Risk, Increasing Sustainability; Strategies for Small-Scale Shrimp Farming in Indonesia

Efficiency of resource use in small-scale white shrimp (Penaeus vannamei) production in Lamongan Regency, East Java Province, Indonesia Wydajność wykorzystania zasobów w produkcji białej krewetki (Penaeus vannamei) na małą skalę w regencji Lamongan, prowincji Wschodnia Jawa w Indonezji

This study carried out to determine the efficiency of recourses used in white shrimp (Pe-naeus Vannamei) production in Lamongan Regency, East Java Province, Indonesia. The simple random sampling technique used to select 125 small-scale white shrimp farmers from six-study areas in Lamongan Regency. The white shrimp production function was es-timated using Ordinary Least Square (OLS) technique. The results indicated that Double Log production function had the best fit in explaining the relationship between output of white shrimp and inputs used. The coefficient of determination (R2 = 0.846) indicated that the eighty-four point six percent of variation in output of white shrimp was explained by the independent variables in the model. Findings showed that labor, fertilizer, feed and stocking density are significant determinants of production inputs. Moreover, the estimates of the ra-tio of the value of marginal product (VMP) to marginal factor cost (MFC) revealed that the non-optimal combination of inputs among the white shrimp farmers, it showed that the aq-uaculture farms resources were inefficiently utilized for labor, feed and stocking density by 1.94, 1.93 and 171.4 respectively, while fertilizer showed otherwise by 0.11 or over uti-lized
