<![CDATA[Industrial growth and population growth have an impact on increasing energy needs. According to the Central Statistical Agency of the Republic of Indonesia in 2020, the population in Indonesia has reached a figure of 273.5 million people, and according to the International Energy Agency (IEA), by 2030, the world's energy demand will have increased by 45%. Approximately 80% of the world’s energy needs come from fossil fuels. In addition, the use of organic waste is the biggest unresolved challenge. Rice husk, which is high in cellulose, is one such organic waste. Many industries in Indonesia also cause water pollution, which causes algae in the waters to increase. For example, a water hyacinth that is left to grow can damage the aquatic ecosystem. This plant produces high levels of carbon and cellulose. Therefore, innovation is needed, such as the utilization in organic batteries and bioethanol gel as renewable energy source. The aim of this research is to utilize waste as a renewable energy source and to know the suitability of the product. This research method is experimental with the acquisition of data from the study of libraries. The types of data obtained are qualitative and quantitative variables. The battery manufacturing process consists of drying, combustion, and packaging. The process of making bioethanol gel includes the stages of pre-treatment, hydrolysis, and fermentation. The results obtained from this study are batteries and bioethanol gel from rice husk and water hyacinth. Keywords: Battery, Bioetanol Gel, Water Hyacinth,Rice Husk]]>
