Utilization of greenbelt zone around the dam Study case: Logung Dam, Kudus Regency, Central Java

Abstract

Dams have an important role, especially in Indonesia, not only as a water source, agriculture also plays a role in controlling floods and hydropower. Many dams have been built and some are under construction. In line with its existence and function, the existence of dams also faces several problems, one of them is erosion problem which threatens the sustainability of the dam function. Land conversion in upstream and around areas contributes to erosion. Natural landscape around the dam must certainly be maintained into the Greenbelt zone. On the one hand its existence must remain part of the natural landscape but on the other hand it will still function as part of the settlement area. The study is intended to map the greenbelt area that must remain natural and which areas can be utilized. Research begins by identifying physical conditions along the edge of the dam, then analyzing it and combining it with existing land use data, resulting in a map of utilization along the edge of the dam (greenbelt).
