SUPPORTABILITY OF LAND RESOURCES FOR DEVELOPMENT OF SOYBEAN (Glycine max) PLANT COMMODITY IN JEMBER DISTRICT, EAST JAVA

Abstract

Land suitability is the level of suitability of a land for certain uses, such as agricultural land, industry and housing. Plants will have high production if planted on suitable land. Soybean plants are one of the crops in Indonesia that have low productivity levels. Appropriate land use can increase the productivity of soybean plants, so research needs to be done on determining the suitability of soybean crop land. The purpose of this study is to determine the class of soybean crop suitability in the Bedadung watershed area and determine the priority areas for developing soybean plants in the Bedadung watershed area. Based on existing data, we classify 7 (seven) parameters. These parameters are soil type, land slope, land use and land cover, average temperature, humidity, rainfall, and erosion hazard level. The research results found that the soybean land suitability class in the Bedadung watershed area was S3 (accordingly marginal), S2 (quite appropriate), and N (not appropriate). Where the, S3 area is 40539.90 Ha (48.79%), S2 area is 42168.67 (50.75%) and N area is 378.96 (0.46%). The priority areas for soybeans plantation in the Bedadung watershed are distributed at 21 sub-districts including Krucil, Rambipuji, Sukorambi, Kaliwates, Ajung, Jenggawah, Patrang, Sumbersari, Arjasa, Pakusari, Kalisat, Sukowono, Ledokombo, Sumberjambe, Panti, Ambulu, Pakem, Maesan , Grujugan, Tamanan and Jelbuk. Whereas there are 3 Subdistricts that are not suitable for planting soybean crops, namely Puger, Balung and Wuluhan Subdistricts. Improvement efforts needed to overcoming limiting factors such as good irrigation system to increase the availability of water, planting cover crops for erosion reduction and many other businesses which can be done to overcome the limiting factors.
