ANALISIS PERUBAHAN BILANGAN KURVA ALIRAN PERMUKAAN PADA BEBERAPA SKENARIO PEMANFAATAN LAHAN DI SUB DAS LATOMA, DAS KONAWEHA, SULAWESI TENGGARA
Abstract: Sub watershed of
Latoma has to be considered as an area of the important regions in South East
Sulawesi, because it takes a great responsibility as a water supplier in
Konaweha watershed. Konaweha watershed is a source of irrigation and domestic
water for Kolaka Regency, Konawe Regency, South Konawe Regency and Kendari
Municipality which has been recently in a critical condition. For this reason,
it should be well managed. This study was implemented with the aim of
establishing model of land use in Latoma sub watershed that can preserve the
land and water resources. The method employs a system analysis with simulation
technique by using the Run-off Curve Number (CN) model based on Geographical
Information Systems (GIS). The result of the research revealed that the run-off
curve number is 70,34. It showed that maximum potential water retention or
infiltration rate is 107,10 mm. Restructuring of land use pattern should be
done to improve the condition of the area to achieve a sustainability
objectives.
