Potential Analysis of Rice Straw as an Alternative Energy Source for Substitute Coal in Indonesia

Abstract

The study of the potential of rice straw was conducted to determine the potential energy of rice straw available as substitute energy sources of coal in Indonesia. The statistical data of rice production Indonesia in 2001-2012, used to analysis of the development potential of rice straw each year. Province are analyzed by 27 provinces have greater rice production of 100,000 tons per year. The analysis showed that the potential of rice straw and potential electrical energy increased by approximately 36.8 % over 12 years, an increase of approximately 3.1 % per year. The potential of rice straw in 27 provinces gained about 91.753 million tons which is equivalent to approximately 50.974 million tons of coal, electrical energy potential of about 382.305 GWh, and the potential power capacity about 43.642 MW. It was concluded that the energy potential of rice straw in 27 provinces in Indonesia is quite large and is increasing every year. Exploiting this potential as a source of electrical energy, can overcome the shortage of electrical energy and can reduce the use of coal in Indonesia.

Energi Terbarukan dari Jerami Padi : Review Potensi dan Tantangan Bagi Indonesia

“…Dengan nilai kalori rata-rata 14.32 GJ/ton, maka potensi energi jerami padi adalah 693 PJ/tahun, setara 19.25 juta kiloliter solar. Potensi jerami padi ini diperkirakan meningkat dengan laju 3.1%/tahun (Makhrani, 2014).…”

“…Pembakaran langsung merupakan proses termal yang paling banyak dipilih untuk keperluan industri kecil (pembakaran batubara, genteng) hingga pengoperasian turbin uap skala kecil. Pemanfaatan jerami untuk bahan bakar pembangkit dapat mengatasi masalah kelangkaan listrik di Indonesia (Makhrani, 2014). Pembakaran langsung merupakan teknologi pembangkit listrik dari jerami yang paling menjanjikan (Suramaythangkoor and Gheewala, 2010).…”

Potential Surplus of Rice Straw as a Source of Energy for Rural Communities in Indonesia

“…where RSt = rice straw produced overall rice production obtained by (Eq.1), RSi = rice straw as raw material for small industries, RSa= rice straw for animal feed, RSw = rice straw as waste. Determination of potential energy of RH surplus can be done based on previous study [6][7], by the equation:…”

Improving Fuel Quality of Rice Straw Through Soaking Using Wastewater from Tofu Industry

“…Rice straw production in Indonesia reaches 2.0 to 3.9 tons of dry weight (bk) per ha per harvest, or about 4.0 to 7.8 tons per ha per year [2]. Along with the development of rice production, the potential for straw in Indonesia is very large and continues to increase by around 3.1% per year [3]. Referring to the figures given by Abraham et al (2016) [4], the potential for Indonesian rice straw in 2017 is between 81.38 million tons to 122.07 million tons.…”
