The potentials of jackfruit (Artocarpus heterophyllus) skin wastes as a supercapacitor biomaterials

Abstract

Background: In modern times, the use of electrical energy cannot be separated from everyday life. The consumption of electrical energy in Indonesia itself is increasing along with the increasing number of people who use electrical energy as lighting and electrical equipment to support comfort in everyday life. Indonesia is one of the countries with abundant biological wealth, one of which is jackfruit (Artocarpus heterophyllus) which is very popular for consumption by all groups. Where jackfruit skin has a lot of content that can be utilized. Methods: Therefore, researchers are interested in examining "The Potential of Jackfruit Peel Waste as a Supercapacitor Biomaterial". The experimental design used is a complete randomized design (CRD) with two treatments, each treatment is repeated three times, namely: P-1 : Activation of 0.1 M NaCl in solid form. P-2 : Activation of 50% HCl concentration in the form of solids.  Findings: The highest average voltage indicator produced is in P-1. The highest average for lights on is 0.053. The highest average for lights to stay on when removed is 0.003. The highest average for the length of time the lights stay on when the battery is removed after 10% slow motion is 0.0067 seconds, and the highest average voltage is 0.073 volts. ash is formed more densely so that it produces electricity more stably than the others. Conclusion: The minimum voltage that can be used for electrical energy sources is 1.3 volts and the size of the voltage can be influenced by the water content, calcium, sodium, magnesium in the fruit peel and the level of fruit maturity. Novelty/Originality of This Study: This study introduces the novel use of jackfruit peel waste as a supercapacitor biomaterial, highlighting its potential as an alternative, sustainable energy source through experimental voltage performance analysis.
