Abstract
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.

Summary
Indonesia has a variety of activities in agriculture. One of the agricultural activities is rice farming. Rice plants produce rice where rice is a staple food for the people of Indonesia. All rice produced is sold by farmers and is a staple food for Indonesians. For rice husk, it will usually be used by brick craftsmen as fuel to burn bricks. The results of the remaining rice in the form of rice husk have been used for several activities but not all of them have been utilized. The activity of burning rice husk can be stopped by making maximum use of these materials. Other utilization of rice husk in addition to raw materials for burning bricks and as a planting medium is to use them as raw materials for anaerobic biogas formation. Biogas is used directly for gas, but can be converted into electricity and heat energy [7]
