Pekalongan Purse Seiners Fisheries Technical Efficiency Using Stochastic Frontier Panel Data

Along 2000-2010, purse seiners fishing fleets in Indonesia dwindled 4.02 percent. In Pekalongan Fishing Port, Central Java has the similar condition. The objectives of this study were to determine the technical parameters of purse seiners fisheries and to compare the technical efficiency of purse seiners in Pekalongan using stochastic frontier analysis (SFA) with panel data. The study applied two models to measure purse seiners efficiency. Model 1: Random-effects Model with panel data will be estimated with Maximum Likelihood and Model 2: Fixed-effects Model SFA for panel data estimated by LSDV. Independent variables used in this study were fishing days, GRT (Gross Registered Tonnage), number of crew members. Dependent variable was the production of purse seine vessels production from 2015-2017. The results of this study indicate the efficiency value in the use of three input variables in the Random-effects model and the Fixed-effects model was quite low. According to Hausman test, Fixed-effects method gives a better output than the Random-effects model in predicting the parameters coeficient because it reduces the bias of the misspecification model. Input variables fishing days and crew members have a significantly effect to gain purse seiners production.
