Land cover changed and economic achievement of farmers in the Rawas subwatershed area

Abstract

Watershed management is intended to provide maximum economic benefits for local communities without neglecting environmental sustainability. The problem in this paper are how changes in land cover and how economic achievements in the form of income of conversion and non-conversion farmers in Rantau Kadam Village, Karang Dapo District. The data collected consists of primary data and secondary data. Land cover was analyzed using ArcMap Ver.10.2 with Landsat 8 for path/row 124/62 and 126/62 for image analysis. Meanwhile, the amount of income is determined using the formulas of income (NR), revenue (TR) and cost of production (TC). The land cover change was carried out by comparing the land cover map in 2009 with the land cover map in 2013 and 2018. The results showed that there had been changes in land use in Rantau Kadam Village, especially fields, open land and plantations. The use of open land has continued to increase from 1.83% (in 2009) to 8.77% (in 2013), and in 2018 it was 37.26%, while fields and plantations showed a decreasing trend. In conversion, it was found that the income of non-rubber converting farmers had a lower income value than oil palm conversion farmers. The average income of farmers per hectare per year for rubber commodity farmers is IDR 5,515,029.42/ha/year, while oil palm conversion farmers are IDR 17,109,341.38/ha/year. The policy implication that can be taken is that there must be institutional strengthening so that the selling price that applies between farmers can be the same.
