Fossil fuels become decreased from day to day because of currently increasing
dependence on it. In order to save our resources without compromising our needs,
renewable fuels offer the best solution. The renewable fuels such as biodiesel are
known for their environmental friendliness. An experiment was carried out to produce
biodiesel from plant-based new cooking oil and used cooking oil. This study proposes
a simple method to monitor standard of biodiesel properties which is through pH
measurement and relate it to the acid number. The pH of biodiesel samples was
measured and the acid number of oil sample was then determined by using the
potentiometric titration method according to ASTM Standards. pH value for biodiesel
produced from new cooking oil was found more acidic than the biodiesel obtained
from used cooking oil. The findings from this study are useful in developing a simple
quality measurement method for biodiesel.
