Initial evaluation of land use potential using geospatial analysis at Sendang Biru Beach, Malang Regency, East Java Province, Indonesia

Abstract

Abstract The use of ArcGIS for geospatial analysis is vital as the first step in earth research. The research focused on Sendang Biru Beach, Tambak Rejo Village, Malang Regency, East Java Province, Indonesia. Based on the analysis of topographic, geological, and land use data, Sendang Biru Beach is located in a basin to a hill with an average height of 125 masl. Geologically, it is located in the Wonosari Formation, flanked by the Qas (swamp and river deposits) and the Tomm (Mandalika Formation). Furthermore, land use is dominated by dry forests. The basin is used for plantations, settlements, and scattered fields and has a karst aquifer flowing all year round, including springs that have diffuse and fissure channel types. The water quality in the area is still within normal limits, has not experienced contamination of seawater intrusion. Sendang Biru Beach Land in Tambak Rejo Village, the ideal development is directed at Fisheries and Coastal Tourism, supported by the presence of extensive dry forest land, karst aquifer resources, and the existence of Sempu Island as a nature reserve.
