Bioelectric Potential of Phaleria Macrocarpa (Mahkota Dewa) Fruit

Voltage Measurement and Application as an Alternative Power Source

Abstract

The use of electrical energy from year to year is increasing, but the source has limitations. This electrical energy crisis must be addressed immediately, one way of which is using environmentally friendly and renewable fuels. One of the environmentally friendly sources of electricity is the fruit of the mahkota dewa (Phaleria macrocarpa). The purpose of writing this paper is to investigate the benefits of the crown of the gods as an alternative source of electrical energy. The subject of this research is the crown of the god fruit, specifically those that are ripe and marked by a red color, which will be used as an alternative source of electrical energy to replace batteries. In addition to its medicinal properties, the results of this study indicate that the crown of the god fruit contains alkaloid compounds (bases) that can generate electricity. The electric voltage generated by the four pieces of the crown of the god can reach 1.8 V. Meanwhile, the current generated from one crown of the god is minimal and only produces a voltage of 0.9 V. The crown of the gods offers several advantages as a source of electrical energy, along with some disadvantages. Based on the research results regarding the power source from the crown of the god, it can be concluded that the hypothesis stating there are benefits to using the crown of the god as an alternative source of electrical energy is valid.
