Provision of land resources for the sustainable sengon raw material industry in Bedadung Jember Watershed
Abstract
Sengon (Paraserianthes falcataria) is a mainstay commodity as an industrial raw material, so it has high economic value. The domino effect that appears is the increase in the area of sengon land and causes changes in land use. Land conversion will be vulnerable to erosion and increase the level of erosion hazards. Inappropriate land changes will also threaten the sustainability of the agroindustry, therefore it is necessary to evaluate the suitability of the sengon plant land. This study aims to identify the suitability of sengon land in the Bedadung watershed for sustainable agro-industry development. The analyzed parameters are 14 and the method used is matching and overlay. The results of land suitability analysis on dominant sengon plants were categorized as S3 "marginally appropriate" (48.07%). The limiting factor for sengon plants is rainfall as a source of water and soil solum. Efforts to increase the rainfall factor are to build reservoirs or dams, but these improvements require a lot of money and time. Meanwhile, efforts to improve soil solum are difficult because it takes a long time. Thus, the sengon commodity in Jember Regency will experience sustainability problems if the limiting factor is not found a solution.
