Abstract

An effort to obtain alternative energy is still interesting subject to be studied, especially production of biogas from agriculture waste. This paper was an overview of the latest development of biogas researches from rice husk waste by Solid State Anaerobic Digestion (SSAD). The main obstacle of biogas production from rice husk waste was the lignin content which is very difficult degraded by microbes. Various pretreatments have been conducted, either physically, chemically as well as biologically. The SSAD method was an attractive option because of the low water content of rice husk waste. The biogas yield by SSAD method gave more attractive result compared to Liquid Anaerobic Digestion (LAD) method. Various studies were still conducted in batch mode laboratory scale and also has not found optimum operating conditions. Research on a larger scale such as bench and pilot scale with continuous systems will be an increase trend in the future research.

Highlights

Among of the global problems today is the issue of energy availability
As an agrarian country that advanced in the field of industrialization, Indonesia has a very abundant biomass waste, including all industrial waste farms and livestock Biogas is an energy produced by organic matter fermented under anaerobic conditions [1]
Biogas production research from rice husk waste by Solid State Anaerobic Digestion (SSAD) method has been done by several researchers in laboratory scale

Summary

Introduction

The Indonesian government's efforts in addressing to cover this problem is by releasing the Government Regulation No 5/2006 about the use of new and renewable energy. Under this regulation, the Indonesian government targets to utilize new and renewable energy sources of 17% of the national energy mix in 2025 from the current of 5%. Along with technological developments and the potential of natural resources, this target is raised to 25% in the new vision referred to as the 25/25 vision. This effort can be classified in energy diversification and energy intensification. Biogas can be used as fuel for vehicles as well as for power and heat generation [3]
