Abstract

Tilapia aquaculture has become one of the most rapidly growing freshwater fisheries sectors in Indonesia due to increasing market demand, adaptive fish characteristics, and relatively simple cultivation techniques. However, the sustainability and productivity of tilapia farming are highly influenced by land suitability and environmental conditions. This study aimed to analyze land suitability for tilapia cultivation in Tanjung Alam Village, Asahan Regency, North Sumatra. The research employed a descriptive quantitative approach using field observations, water quality measurements, interviews, and Geographic Information System (GIS)-based suitability analysis. The observed parameters included temperature, dissolved oxygen, pH, water depth, current velocity, soil texture, salinity, accessibility, and supporting infrastructure. Data analysis was conducted using a scoring and weighting method to determine the level of land suitability for tilapia aquaculture development. The results indicated that most areas in Tanjung Alam were categorized as moderately suitable (S2) to highly suitable (S1) for tilapia cultivation. Water temperature ranged from 27–30°C, dissolved oxygen ranged from 5.1–7.2 mg/L, and pH values ranged from 6.8–7.8, all of which support optimal tilapia growth. Accessibility and water availability were also considered adequate for sustainable aquaculture activities. The study concludes that Tanjung Alam possesses considerable potential for the expansion of environmentally sustainable tilapia farming. The findings provide strategic recommendations for regional aquaculture planning and sustainable fisheries development.
