Assessment of Horse Shoes Lake (Oxbow) Conservation Assessment of Rantau Baru Village, Pelalawan Regency, Indonesia

Abstract

The damage to oxbow lakes in various places in Indonesia has not been managed properly, so it is feared that its existence will disappear. Whereas the function of the Oxbow Lake, among others, is as a provider of water and fishery resources. Realizing the importance of the oxbow lake, this study was conducted on two lakes in Rantau Baru, Pelalawan Regency based on the land cover method and the Water Quality Index (WQI) calculation method. Water samples were taken at three points from the two observed lakes. WQI is calculated based on ten parameters, namely pH, conductivity, dissolved oxygen (DO), Depth, Total Phosphate, Ortho-phosphate, Total Nitrogen, Nitrate as N (NO3), Nitrite as N (NO2), Ammonia as N (NH3). The results showed that the lake Sepunjung half of its water body is covered with water hyacinth (Eichhornia crassipes) and the WQI value is classified as good. Teluk Bederas lake on the outskirts of the lake contains oil palm and plantations and from the WQI value it can be concluded that it is in poor condition.

Sustainability Management of Teluk Benderas Lake, Rantau Baru Village, Pangkalan Kerinci District, Riau Province

“…In the upstream part of the village along the Kampar River, since 2010 the people have planted oil palm, whose fertilizer waste has polluted the waters. The water quality of Teluk Bederas Lake is classified as bad due to agricultural activities and oil palm plantations that reach the lake's lips [1]. In the context of conservation, it is prohibited to catch fish with tuba and poison, cutting down trees around the lake [2].…”
