Optimalisasi Lahan USAhatani Berbasis Kakao Untuk Pembangunan Pertanian Berkelanjutan Di DAS Krueng Seulimum Provinsi Aceh (Land Optimization of Cocoa Based on Farming for Agricultural Sustainable Development in Krueng Seulimum Watershed Aceh Province)

摘要

Land use changes in the Krueng Seulimum watershed into agricultural land without application of suitable agro-technology have led to high erosion and low land productivity. This study aims to assess the characteristics of the land and agro-technology applied the cocoa crop, analyze the allocation of optimal land for cocoa farming and suitable agro-technology to reduce erosion and to increase farmers\u27 income and formulate cocoa based on sustainable farming plans. The results show that sustainable cocoa based farming can be achieved with the implementation of agro-technology with complete fertilizer at 7% slope, complete fertilizer plus making grass planted bund-terrace at 14% slope and making grass planted bund terrace plus mulching 6 ton.ha-1.year- at the 21% slope, to reduce erosion less than ETol and provide farming income bigger than the need for minim living standart (MLS). Cocoa farming type plus banana (KPs) in the Krueng Seulimum watershed on 1.5 ha land area by applying agro-technology bund terrace plus mulching 6 ton.ha-1.year-1 can suppress erosion under ETol (16.03 - 38.64 ton.ha-1.year-1) with optimum income of Rp 42,954,150 kk-1.year-1.
