Abstract

Biodiesel was characterized as an alternative fuel for diesel engine, derived from palm oil methyl ester blends with diesel fuel. Biodiesel has a hygroscopic characteristic that could dissolve more moisture than petroleum diesel. Water content in biodiesel is an important parameter in the production, storage and distribution of biodiesel. Water content in biodiesel can cause problems such as water accumulation in fuel storage, transportation, and handling equipment which could lead to reducing the lubrication of fuel that make engine wear, damages injection, corrosion, and catastrophic failure. Currently, there is a lack of information on the water content in B20 (20% of biodiesel blend). This study reports the saturation point of Indonesia’s B20 at several temperatures (30 ̊C, 35 ̊C, 40 ̊C, 45 ̊C). The test method utilizes the humidity sensor and temperature sensor. The result shows the graph of saturation point of B20 in varies temperature. The proposed study is expected to be a guidance for B20 storage in order to keep B20 from free water.
