Suitability Analysis of Vaname Shrimp (Litopenaeus vannamei) Cultivation Locations Based on the Physical and Chemical Aspects of Water in Patebon Sub-district, Kendal Using Geographic Information System

Abstract

Patebon sub-district is an area that produces little Vannamei shrimp. Only about 9.3% of the pond area is used for shrimp cultivation, so it is necessary to conduct a feasibility analysis of the location to further develop Vannamei shrimp cultivation there. The purpose of this study was to analyze the feasibility of aquaculture ponds and to estimate the potential production of each sampling location based on dissolved oxygen values. The method used in this research was a case study. The sampling location was determined by a purposive sampling method. V ariables used in the analysis of water quality are dissolved oxygen, salinity, brightness, depth, temperature, pH, ammonia, nitrate, and phosphate; production analysis is measured based on dissolved oxygen content. Data processing was performed using ArcGis 10.3 with the stages of making a basic map, spatial map based on results, scoring, overlay, and layout. The results of the site suitability analysis showed that the pond area was categorized as S1 (Very suitable) with an area of 257 Ha and S2 (suitable) with an area of 33 Ha. The estimation results of potential products based on dissolved oxygen values are 1.667.790 kg.
