Abstract

Rawapening Lake has undergone many changes that can be seen from the uncontrolled water hyacinth, even in the dry season, it can cover the surface of the lake up to 70%. The rapid growth of water hyacinth requires proper handling. The purpose of this research is to analyze the utilization of water hyacinth in Rawapening lake optimally as renewable energy source. Stages in this research are: (1) Preparation stage contains problem identification, how to analyze optimization of Rawapening lake water hyacinth utilization as renewable energy source; and literature studies on water hyacinth, Rawapening lake, and renewable energy; (2) Data Collection Phase about water hyacinth, Rawapening lake, and renewable energy from water hyacinth. At this stage the researcher conducts field surveys and interviews of local residents; (3) Data Processing Phase which contains related data processing and data analysis; and (4) Final Stage, which is the optimization analysis of the utilization of water hyacinth (Eichhornia crassipes) Rawapening lake as a renewable energy source. The result of this research: (1) result of analysis indicate that from the 30% of the land utilization of Rawapening lake for hyacinth area of 8,010,000 m ; (2) the potential of methane gas produced is 92,731,276.451 m 2 , it produced potency of biogas volume per day equal to 142,663,502.232 m 3 . This gas can be converted into electrical energy of 1,035,808,357.957 kWh/day or equivalent to 1,035,808.358 MWh/day. This value is equivalent to 310,138,048.331 kg of LPG gas or equivalent to LPG gas production 103,379,349 three kg LPG tube per day; and (3) it is possible to have a natural cultivation of water hyacinth as a source of renewable energy by continuously controlling and considering the survival of Rawapening lake ecosystem including sedimentation of Rawapening lake.
