Abstract

Rawa Pening Lake has been in critical condition, caused by high sedimentation levels, declining water quality, damage to the watershed, and excessive riparian occupation. Therefore, this study aims to identify the main problems of the revitalization of Rawa Pening lake. Data and information collection were carried out through direct observation and interviews. The results showed that the main problems of the lake were the removal of the water weeds/water hyacinths, tidal rice fields, and buildings on the lake and riparian areas. The solution to the three main problems is lake revitalization. The revitalization concept that can be proposed regarding the control of water hyacinth is by mechanical means (using water hyacinth lifting equipment, boats, and cutting water hyacinth) and by biological methods, namely the cultivation of koan fish that will eat water hyacinth. At the tidal rice fields, it is necessary to determine the water level limit wisely. The areas with elevation of 462.30 m3-463.25 m3 (covering an area of 812 Ha) can be planted twice a year. The areas with a height of 462.05 m3-462.30 m3 (covering an area of 200 Ha) can be planted once in the rainy season. The areas with elevation of 462.05 m3 cannot be planted because it is in a state of flooding. Incommensurate areas and lakes, there is a lot of land and buildings consisting of settlements, tourism destinations, places of worship, and restaurants. Then the proposed alternative solution is the land acquisition compensation of land and buildings in commensurate areas.
