Abstract

Biodiesel is generally defined as monoalkyl esters of plant oils and animal fats. Oils derived from plants and animal fats and their derivatives have the possibility as a substitute for diesel fuel. This biodiesel is then mixed with diesel with a composition of 50% biodiesel and 50% diesel to make B50. In this study, B50 was then mixed with diethyl ether. The results of this study, obtained a mixture of B50+0% diethyl ether, B50+2% diethyl ether, B50+4% diethyl ether, B50+6% diethyl ether, B50+8% diethyl ether, B50+10% diethyl ether with kinematic viscosity (6.5 mm2/s, 6 mm2/s, 5.4 mm2/s, 5 mm2/s, 4.3 mm2/s, and 3.6 mm2/s), flash point (183 oC, 179 oC, 177 oC, 175 oC, 171 oC, and 167 oC), pour point (7 oC, 6 oC, 5 oC, 4 oC, 2 oC, and 1 oC), caloric value (10051,66 cal/m3, 10097,1322 cal/gram, 10128,13 cal/gram, 10170,38 cal/gram, 10235,37 cal/gram, and 10306,84 cal/gram), and density 15 oC (841.1 Kg/m3, 839.5 Kg/m3, 838.2 Kg/m3, 837 Kg/m3, 836.2 Kg/m3, dan 835.1 Kg/m3)

Abstract

The study aims to determine the level of beef consumption and the factors that influence the consumption of beef in West Papua. The data used in this study are monthly time series data of BPS, sourced from all districts in the province of West Papua from 1990 to 2004. Data were analyzed by using multiple linear regression equation by Ordinary Least Square method. The results showed that the average beef consumption per capita per year for people of West Papua is 0.79 kg. The increasing of population and income per capita affected the increasing of beef consumption significantly. Increasing the price of chicken meat, pork prices and the price of rice has significant effect of reducing domestic consumption of beef. Increasing the price of tuna, squid and sweet potatoes have a significant effect in increasing of the domestic consumption of beef.
