Analisis Lahan Kritis Dan Arahaan Penggunaan Lahan Pada Sub Daerah Aliran Sungai Binanga Lantang Di Sulawesi Selatan

Abstract

<jats:p>Land use does not the rules of soil and water conservation potentially lead to land causes of degradation that will eventually lead to critical land. The impact ofthe existence of critical landis the decrease of soil fertility, lack of water resoucesin dryseasonandin rain season. Critical land mapping is necessary to determine the right efforts in the management of upper course of Binanga Lantang Sub Watershed until not distrub ecosystem balanced.This study aims to identify the extent and distribution of critical land and formulate appropriate land use directions to suppress degraded land in Binanga Lantang Sub Watershed. The method based on Forestry Departement P.4/V-SET/2013 by overlap method, scoring and weighting of each parameter. The parameters used are map of vegetation class, productivity class map, class map slope, erosion class map and class map management. Reseach results show (1) Classification of critical land after land use direction Binanga Lantang Sub Watershed is very critically broad area 2870,38 ha, critically area 3541,11 ha, rather critically area 4962,34 ha, critical potential 3121,75 ha and not critically area 170,95 ha. (2) critical land Binanga Lantang Sub Watershed to reach 43,72 percen of the total watershed area. The entire production forest area is critical, the protected forest arund 50 percent of the area is in critical condition and other uses are only 20 percent of the area is in critical condition. (3) One of the efforts that can be done to minimize the increase in land criticality is agroforestry and rehabilitation.</jats:p>

Implementasi Instrumen Zoning Regulation dalam Penanganan Lahan Kritis di DTA Kaskade Mahakam

“…Adapun penelitian ini bertujuan untuk merumuskan arahan penanganan lahan kritis di DTA Kaskade Mahakam berdasarkan arahan zonasi lahan kritis. Penentuan tingkat kerawanan lahan kritis berdasarkan variabel dan bobot penentu lahan kritis dengan metode overlay untuk melihat kemampuan daya dukung lahan seperti yang dilakukan oleh penelitipeneliti terhadap lokasi lain (Nurhakim, 2017;Ruhama et al, 2020;Widyatmanti et al, 2018). Sementara itu, penentuan arahan penanganan lahan kritis pada fungsi penggunaan lahan dan teknik konservasi yang dilakukan berdasarkan zona dan tingkat kekritisan lahan pada kawasan DAS dan kawasan danau juga dilakukan beberapa peneliti lain (Melo et al, 2018;Nugroho, 2000;Sule et al, 2021).…”

Analisis Sebaran Lahan Kritis Kawasan Hutan Pada Daerah Aliran Sungai (DAS) Pengabuan

“…Exploitasi sumberdaya lahan secara berlebihan tanpa mempertimbangkan kaidah konservasi menjadi pemicu peningkatan luasan lahan kritis. Dijelaskan Ruhama (2020), bahwa tataguna lahan yang tidak mempertimbangkan konservasi berpotensi menimbulkan lahan kritis. Menurut Indrihasturi et al, (2016), dampak lahan kritis yaitu penurunan kualitas tanah hingga menurunkan fungsi konservasi.…”
