Perubahan Luas Tutupan Mangrove dan Keterkaitannya dengan Produksi Tambak Udang di Kecamatan Labuhan Maringgai dan Pasir Sakti Kabupaten Lampung Timur

Abstract

Meeting the needs of shrimp aquaculture land causes environmental disruption due to using mangrove ecosystems converted into shrimp ponds. Mangrove forest area and shrimp aquaculture production are two things that synergize with each other. Both are coastal potentials that must be developed by applying sustainable development patterns. This study aimed to analyze the relationship between mangrove cover area and shrimp pond production and formulate sustainable mangrove management that supports shrimp pond production in Labuhan Maringgai and Pasir Sakti Districts of East Lampung Regency. Changes in mangrove cover area were obtained using satellite imagery and processed using ArcGIS. The relationship between mangrove area and shrimp production was analyzed using regression analysis, and mangrove management that supports shrimp pond production was processed using the Analytic Hierarchy Process (AHP). The results showed that the relationship between mangrove cover area and shrimp pond production is significantly different. The regression analysis results between mangrove cover area and aquaculture production resulted in a regression equation Y = 29.91X - 19024 with a r² value of 0.892. An alternative mangrove management scenario that supports the production of shrimp ponds based on environmental, economic and social aspects is scenario 1, with an eigenvalue of 0.42. Scenario 1 is mangrove management by planting mangroves in the land and replacing damaged / dead mangroves in mangrove land and shrimp pond production generated by the use of aquaculture technology: traditional 68.10%, semi-intensive 10.57%, intensive 21.33%.
