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 theexpected value of production that is likely to be obtained. Porang plant is one of the plantsbelonging to the Araceae family and is a shrub (herb) plant with a single tuber inside. Poranggrows a lot in the forest because it only requires 50-60% sunlight so, it is very suitable forplants 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 usesdescriptive analysis. Namely, the research data is displayed in the form of tables and maps. Thedata 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 fourclasses, 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 landsuitability in all aspects of the parameters. The overlay obtained in the Suela sub-district for thesuitability of the Porang plant land was in one class, which was very suitable (S1) for all areasin the village of Suela sub-district, East Lombok regency.
