Health and Study Bogowonto Watershed Management Based on Hydrological Indicators

Abstract

The Bogowonto watershed was used as a research location because it is one of the largest watersheds with an area of 605.91 km ² and has a sizeable contribution to the sustainability of water resources in Central Java Province. Watershed health assessment is intended to determine the level of health of the watershed by reviewing it watershed hydrological indicators based on the quantity of surface water. Relationship between indicators hydrology with the watershed health index described by the power regression model. Recommendations or directions watershed management planning priority scale from the results of an assessment of the appropriate watershed health level with PP RI No. 37 of 2012 concerning Watershed Management. The results of the analysis show that the health level of the Dodokan watershed from 2011 - 2020 is dominated by medium category. Connection watershed health index (IKD) with hydrological indicators yields which shows that the watershed health index is a function of hydrological indicators. watershed management planning recommended in the future is by: 1) the application of the technique soil and water conservation is carried out in order to maintain the continuity of the water catchment area, maintain the quality, quantity, continuity and distribution of water and 2) vegetation management is carried out in the context of conserving biodiversity, increasing land productivity, restoration ecosystem, rehabilitation and land reclamation.
