MAPPING OF THE POTENTIAL WATER SPINACH COMMODITY IN SIDOARJO DISTRICT USING LOCATION QUOTIENT AND GEOGRAPHIC INFORMATION SYSTEM

Abstract

Sidoarjo Regency is known for its superiority in the agricultural sector. The farm sector in Sidoarjo Regency is also reasonably crucial in supporting regional economic growth. Water spinach is a vegetable that most people in Indonesia widely consume. Reviewing the enormous potential of water spinach vegetables in Indonesia, Sidoarjo Regency has great potential in making water spinach a superior regional commodity. Determining the superiority of commodities in each sub-district in Sidoarjo Regency can be done using the Location Quotient (LQ) method. Based on the differences in potential in each sub-district, mapping is needed so that the potential of water spinach can be described visually using the Geographic Information System method. Based on the analysis that has been carried out, it was found that most areas in Sidoarjo Regency are the base sector for water spinach commodities. These sub-districts include Tarik, Krembung, Prambon, Tanggulangin, Candi, Tulangan, Wonoayu, Sidoarjo, Buduran, and Balongbendo. The percentage of areas in the base sector reaches 55.55%. The base sector indicator is obtained from the calculation value of LQ> 1. The LQ value>1 indicates that the water spinach commodity in this sub-district is able to meet the needs of its region and is also able to supply the needs of other areas.
