Abstract

Lahan merupakan sumber daya alam yang dapat dimanfaatkan secara berkelanjutan. Setiap jenis tanaman mempunyai syarat tumbuh yang berbeda- beda sehingga perlu diketahui tingkat kesesuaiannya. Penelitian ini bertujuan untuk menentukan kelas kesesuaian lahan pada tanaman karet ( Hevea brasiliensis Muell Agr) di Nagari Panyubarangan Kecamatan Timpeh Kabupaten Dharmasraya Provinsi Sumatera Barat. Penelitian ini terdiri dari dua tahap yaitu penelitian lapangan di Nagari Panyubarangan dan analisis tanah di Laboratorium Balai Pengkajian Teknologi Pertanian (BPTP). Pengklasifikasian kesesuaian lahan untuk tanaman karet dilakukan dengan metode matching yang pada dasarnya mengacu pada petunjuk evaluasi lahan untuk komoditi pertanian. Hasil penelitian menunjukkan bahwa semua Satuan Lahan I, II, VI, dan VII di Nagari Panyubarangan tergolong kedalam Sub-kelas kesesuaian lahan S3nr (Sesuai Marginal) dengan faktor pembatas retensi hara (kejenuhan basa dan pH),. Satuan Lahan III dan V tergolong kedalam Sub-kelas kesesuaian lahan S3nr,eh dengan faktor pembatas retensi hara (pH), dan bahaya erosi (lereng). Satuan Lahan IV tergolong kedalam Sub-kelas kesesuaian lahan S3oa,rc,nr,eh,fh dengan faktor pembatas ketersediaan oksigen (drainase), media perakaran (kedalaman tanah), retensi hara (pH), bahaya erosi (lereng) dan bahaya banjir (banjir). Kata Kunci : kesesuaian lahan, karet, panyubarangan EVALUATION OF LAND SUITABILITY FOR RUBBER PLANTS (Hevea bresiliensis Muell Agr) IN NAGARI PANYUBARANGAN KECAMATAN TIMPEH DHARMASRAYA DISTRICT WEST SUMATERA PROVINCE Land is a natural resource that can be utilized sustainably. Each type of plant has different growing conditions so it is necessary to know the level of suitability. This research aims to determine the land suitability class of rubber plants (Hevea brasiliensis Muell Agr) in Nagari Panyubarangan, Kec. Timpeh, Kab. Dharmasraya, Prov. Sumatera Barat. This research consists of two stages, namely field research in Nagari Panyubarangan and soil analysis at the Laboratory of Agricultural Technology Research Institute (BPTP). Classification of land suitability for rubber plants is carried out by matching method which basically refers to the instructions for evaluating land for agricultural commodities. The results of this research indicate that all Land Units I, II, VI, and VII in Nagari Panyubarangan belong to the Sub-class of land suitability S3nr (Corresponding Marginal) with limiting factors for nutrient retention (base saturation and pH). Land units III and V are included in the S3nr,eh land suitability class with limiting factors for nutrient retention (pH), and the risk of erosion (slope). Land units IV are classified into land suitability S3oa,rc,nr,eh,fh Sub-class, with limiting factors for oxygen availability (drainage), root media (soil depth), nutrient retention (pH), erosion hazard (slope) and flood hazard (flood). Key word : land suitability, rubber, panyubarangan.
