Analisis Keluaran Tegangan dari Pembangkit Listrik Berbasis Kelembaban (Moist Electric Generator)

Abstract

Batteries contain carbon rods that can be recycled into more useful and efficient materials. Carbon rods obtained from battery waste can be processed into graphene oxide (GO) or reduced graphene oxide (rGO). These materials are highly effective materials for the manufacture of high-value products, especially electronics. GO is the result of the oxidation of graphite with the addition of oxygen, which breaks some of the van der Wall bonds and reduces the thickness of the sample. On the other hand, rGO is the result of the reduction of oxygen from GO, and the functional group in the GO plane, i.e. oxygen, is removed and the electrical conductivity increases from 340/Ωcm to 550/Ωcm. In this study, rGO is used as a moisture absorber used in moisture-based power plants (MEG). To maximize moisture absorption, rGO is given a mixture of hygroscopic compounds, namely PVA. In analyzing the voltage generated from MEG, 3 types of experiments were carried out by comparing the rGO and PVA levels respectively, namely 25:75; 50:50; and 75:25. The average voltage output values obtained from the three types of experiments were 4.26 V, 4.45 V, and 4.69 V. From the three experiments, the greater the rGO level will increase moisture absorption and this will be proportional to the increase in the output voltage of the MEG.
