Productivity Analysis of Mini Purse Seine in PPI Pulolampes Brebes, Central Java, Indonesia

Fish Landing Base (PPI) Pulolampes is one of fishing base mini purse seine in Brebes Regency, Central Java Province. Many fishers in Brebes more choosing mini purse seine to fishing than other. The problem is about productivity level of this fishing gear. Therefore, the purpose of this study was to analyze many factors which influence weight total catch of mini purse seine and analyzed the productivities. The method apllied is case studies. Sampling method used are simple random sampling. Sampling size determined using Slovin formula and obtained 40 vessels as a sample. The data was analyzed using productivity analysis and factors that influenced catch of mini purse seine using SPSS 22 includes basic assumption test and multiple regression analysis. A hypothesis testing consists of normality, multicollinearity, autocorrelation and heterokedastisitas test. Productivity analysis of mini purse seine by gross tonnage (GT) obtained the value - average levels of productivity of 1.56. Based on F test is known that all independent variable can influence dependent variable significantly (R² 95.30%, α < 0.05). T test analysis obtained results that it is only a variable number of trips (X5) that significantly influence the amount of production by the equation Y = 4.431 + 1.061X5, if there is an addition of a number of arrests trip by 1% with assuming that all variables are fixed, there will be additional fisheries production amounted to 1.061%.
