Land Evaluation And Suitability For Porang (Amorphophallus Muelleri) in Suela District, East Lombok Regency Using Geographic Information Systems (GIS)

Abstract

Land evaluation is an approach or method to assess potential land use required and the
expected value of production that is likely to be obtained. Porang plant is one of the plants
belonging to the Araceae family and is a shrub (herb) plant with a single tuber inside. Porang
grows a lot in the forest because it only requires 50-60% sunlight so, it is very suitable for
plants in the shade. This study aims to determine the suitability of Porang land in Suela District,
East Lombok Regency, using Geographic Information Systems. This research method uses
descriptive analysis. Namely, the research data is displayed in the form of tables and maps. The
data includes agro-climatological data (rainfall and temperature), nutrient retention (pH Hâ‚‚O),
Toxicity (salinity). The results of the evaluation of land suitability were categorized into four
classes, namely very suitable (S1), quite suitable (S2), marginally suitable (S3) and not suitable
(N). The evaluation of the suitability of this study obtained a very suitable level of land
suitability in all aspects of the parameters. The overlay obtained in the Suela sub-district for the
suitability of the Porang plant land was in one class, which was very suitable (S1) for all areas
in the village of Suela sub-district, East Lombok regency.
