摘要：Increased rice production in Indonesia not only brings good news socially and economically, but also brings bad news for environmental ecology. In each rice crop produces 50% rice straw and 50% grain. The grain is divided into two again, namely 80% rice and 20% rice husk. In 2018, counted the rice husk up to 10,379,625 tons, a fantastic number if cannot be managed properly so that it can pollute the environment. One alternative to deal with the high rice husk is through conversion to biogas. Biogas is an energy that is formed under anaerobic conditions with organic material so that it is also called renewable energy. The development of research on biogas production from rice husks based SS-AD has experienced a positive increase in hardness. Studies have been conducted on the pre-treatment to other influencing factors. But after the authors describe the latest development of biogas research from rice husk, there are still some variables that have not been tested such as physical treatment, the influence of temperature, pH and alkalinity. Based on this review, further research is needed to complete a number of variables that have not been carried out so that it is expected that the development of biogas production from rice husk based SS-AD can move toward larger scales such as pilot scale and industrial scale.
