Test the electrical content of singi fruit (Dillenia serrata Thunb.) as a source of electrical energy

Abstract

Abstract One of the trees that has fruit with high acid content that has the potential to be used as an alternative energy source is the acid contained in Singi (Dillenia serrata Thunb.) fruit. Therefore, this study aims to test the ability of the singi fruit to turn on the LED lights and determine the value of voltage, current and electrical power in the fruit. This research was conducted at the Laboratory Ministry of Forestry, Faculty of Forestry and Environmental Sciences, Halu Oleo University. In June-July 2019 using an experimental method for 5 days by measuring the acidity (pH) value of voltage, current and electric power. The results showed that the LED was on until the 5th day but the value of the electricity content tended to decrease, namely the first day with a power value of 7.533 watts and the fifth day 1.722 watts. While the acidity (pH) of the singi fruit which is decreasing over time affects the value of the electrical content contained in the solution of the singi fruit.
