Efficiency of drift gillnets in nagan raya district, aceh, indonesia

Abstract

The achievement of technical and economic efficiency is one indicator in assessing the fishing process's capability. The purpose of this study was to formulate production factors of drift gillnets at The Kuala Tadu and The Kuala Tuha fishing base and to calculate the technical and economic efficiency of the use of production factors for drift gillnets at both locations. Production factors that support the success of drift gillnets operation are net depth, net length, boat size, amount of fuel, trip duration, mesh size, and engine power analyzed using the Cobb-Douglas approach. The results showed that the equation of production function for drift gillnet is LnY = 3.110 +0.112 LnX2 + 0.191 LnX3 + 0.105 LnX4 + 0.251 LnX6 with a value of R2 is 0.833. The technical efficiency study of 20 units of drift gillnets showed that the value of production elasticity (EP) for using production factors for net length (0.112), vessel size (0.191), amount of fuel (0.105), and mesh size (0.251) was < 1. It means that the use of factors of production is no longer efficient. The economic efficiency of using the variable production factors of drift gillnets is no longer efficient because the value of NPMxi/BKMxi >1.
