Land priority determination for paddy field extensification in Subang Regency - Indonesia

Abstract

Extensification efforts in agriculture to increase paddy production can be done through the selection of land for the development of paddy fields from available land. Every inch of land has different characteristics, which can be used for the selection of land suitable for a use, including for paddy fields. This study aims to delineate available land and set priorities for the development of paddy fields in Subang Regency. The main methodology used is a multicriteria-based land evaluation. The land attribute is weighted using the AHP technique from the assessment of 8 experts. Land availability was obtained from a combination of Weighted Linear Combination method and Geographic Information System. The results of the study found suitable land for paddy field extensification. Prioritization results showed that 76,115 hectares of land had high priority, 7,165 hectares had moderate priority, 55,280 hectares had low priority, and an area of 19,561 hectares is land that is not recommended for use. The land available for extensification of paddy fields from suitable land is 9,885 hectares with a composition of 73.24% (7,240 hectares) high priority, 21.20% (2,096 hectares) moderate priority, 3.36% (530 hectares) low priority, and 0.19% (19 hectares) are not recommended for paddy field extensification.
