The use of Liquified Petroleum Gas (LPG) in Indonesia is quite high, the volume reaches 6.7 million tons per year. Indonesia currently still imports 70% of its domestic consumption of LPG, or about IDR 40 trillion. Imports of Liquid Petroleum Gas (LPG) continues to increase every year. Dimethyl ether (DME) is one alternative to renewable fuels because its availability in the country is quite abundant. When DME applied as household fuels, some components such as metals and rubber should include resistance to DME, such as stoves, rubber hoses, rubber components in regulators and tube valves. Lemigas has succeeded in developing a DME resistant stove but still not found a rubber that is resistant to DME. This research aims to find a natural rubber formula that is resistant to DME and DME / LPG mixture. The study was conducted by varying the dose of sulphur (0.5, 1.5, and 3.5 phr) using 2 types of elastomer, Natural Rubber (NR) and Nitrile Butadiene Rubber (NBR). Immersion was carried out in DME and 3 variations of the DME/LPG mixture (10/90, 20/80, 30/70). The results showed that the compound formula using natural rubber with a sulphur dose of 1.5 phr has the best resistance to DME and DME/LPG mixtures.
