Abstract

Due to increasing population growth, the consumption and needs of energy increase significantly. This leads Indonesia government to search alternative energy to cover the lacks of fossil energy reserves. Biodiesel is one of the prospective alternative energy which are renewable and environmental friendly. A common problem in large-scale biodiesel production is the sustainability of feedstock and the biodiesel stability. Therefore, the purpose of this study was to evaluate the production of biodiesel from two oil sources i.e. waste cooking oil and castor oil. This study examined the effect of mixed oil ratio on yield, biodiesel characteristics and stability. The physical properties included kinematic viscosity, acid number, saponification number, iodine number and cetane number have been evaluated as function of oil ratio. Yield of biodiesel was obtained at 35.07%, 99.2% and 83.69% for jatropha:castor oil ratio of 1: 0, 1: 2 and 2: 1, respectively. Most of these characteristics showed an increase by increasing the oil ratio. The result concluded that at the ratio of 1:1(v/v) was the best characteristic and stability.

Highlights

Indonesia is the fourth most populous country in the world after China, India, the United States with a population of 237,641,326 people [1]
The growth of the Indonesian population from the period of 2000-2010 averaged 1.49% per year, this gives a broad impact on energy needs
Indonesia's oil reserves currently range from 4 billion barrels with an average oil production of 1 million barrels per day, while the demand for fuel oil reaches 1.2 million barrels per day so that the remainder of Indonesia's fuel needs is still imported

Summary

Introduction

Indonesia is the fourth most populous country in the world after China, India, the United States with a population of 237,641,326 people [1]. The growth of the Indonesian population from the period of 2000-2010 averaged 1.49% per year, this gives a broad impact on energy needs. Energy consumption is still dominated by fuel oil (gasoline, diesel oil, kerosene, aviation fuel and avgas) [2]. Indonesia's oil reserves currently range from 4 billion barrels with an average oil production of 1 million barrels per day, while the demand for fuel oil reaches 1.2 million barrels per day so that the remainder of Indonesia's fuel needs is still imported. The government is trying to develop alternative energy in preparation for the fuel oil crisis. One form of effort that has been done by the government is the utilization of biofuel or biodiesel [2]
