Evaluation of the Suitability of Mung Bean Crop Agricultural Land Using the Geographic Information System (GIS) in Poto Tano District, West Sumbawa Regency

Abstract

Geographic Information System (GIS) is a computer-based information system used to process and store data. This study aims to determine the level of land suitability for mung bean plants using the Geographic Information System (GIS) in Poto Tano District, West Sumbawa Regency and to determine the limiting factors of land suitability in the form of soil texture, soil pH and C- organic to mung bean plants in Poto Tano District, West Sumbawa Regency. The method used in this study is to describe the condition of an object and is expressed in the form of a map, picture, table or graph. The parameters observed include soil texture, soil pH, rainfall, air temperature, slope and C-Organic. The results of the soil texture research in Poto Tano District are mostly clay texture, meaning that the soil composition contains a balanced mixture of clay, dust and sand. The soil pH in Poto Tano District for mung bean plants on the map of all villages is included in the land suitability class with the very appropriate class (S1). The rainfall in the picture shows one color of the layout, namely red, indicating the class of land suitability for mung bean plants in Poto Tano District according to the marginal (S3) with a score value of 2. The air temperature of mung bean plants adjusts to the altitude of the region and the harvest time after rice and corn.  The slope of mung bean plants in the highlands ranges from 2 to 15% for field areas. Meanwhile, using rice fields has a slope slope of 0 – 5% for mung bean plant cultivation. C-Organic shows that Kiantar Village belongs to the fairly appropriate class (S2) with the yellow color, while the other six villages—Senayan, Tebo, Mantar, Tambak Sari, Kokarlian, and Tuananga—belong to the marginal appropriate class (S3) with the red color.
