Electrical Analysis of Combination of Orange Peel and Tamarind for Bio-battery Application as an Alternative Energy

INTRODUCTION
The use of disposable primary batteries can cause pollution to the environment due to the lack of means of treating waste from used batteries so that they end up in the trash (Widyaningsih & Mulud, 2017). One of the efforts to reduce this pollution is by making biobatteries (Ratnawati, et al., 2010). Bio-battery is a device that generates electrical energy from materials derived from living things. Fruits are among the ingredients with the greatest potential to be used as bio-batteries (Fauzia, et al., 2019). Orange peels (Salafa, et al., 2020) and tamarind (Suciyati & Supriyanto, 2019) have high electrolyte content, so they can be used as electrolytes in batteries.
The purpose of this study was to determine the effect of good electricity on the variation of the combination of orange peel and tamarind for bio-battery. The method used is to crush the orange peel and tamarind until it becomes a paste, mix it according to the variations, and put it in a used battery. The novelty of this research are (1) the use of a combination of biomass of orange peel and tamarind as bio-battery electrolyte and (2) the ratio of orange peel to tamarind. Figure 1 is the process of making a bio-battery using an experimental method. The materials used in this research were orange peel, tamarind, carbon sticks, and used 1.5 volt batteries. Orange peel and tamarind crushed into a paste. After that, the two ingredients are mixed. The variations in the combination of orange peel against tamarind used were 0, 25, 50, 75, and 100%. Then, put into a used battery that has been cleaned. Figure 2 is the result of the voltage test from the variation of orange peel and tamarind ratio. The test results showed that the highest voltage was obtained by the variation of orange peel with a percentage of 25%, namely 1.7 volts, while the lowest was obtained from variations in orange peels with a percentage of 100%, namely 1.43 volt. Changes in the variation of the peel of orange and tamarind affect the voltage (Erviana, et al., 2020) because the ions gather in adhering to the cathode so that the amount of charge flows from anode to cathode. The more ions collected, the higher the voltage generated (Atina, 2015).

Electric Current
Based on the results of observations of electric currents from the variation in the percentage of orange peel to tamarind shown in Table 1. The results showed that the highest value of electric current was owned by the variation of orange peel with a percentage of 25%, namely 1.33 mA, while the lowest value was owned by the variation of orange peel with a percentage of 0%, namely 0.63. In the variation of 0% orange peel has the meaning that the content of 100% tamarind that indicates variations of tamarind in the paste very concentrated, this density results in the content of ions produced very tight and crowded so that the existing ions are difficult to move and produce a small electric current, while in the variation of 25% of existing ions have a wide movement so that it is easy to move because of the decrease in density obtained from orange peel (Fadillah, 2019). The value of this current is influenced by the amount of voltage and resistance in the battery (Abidin, et al., 2020).

CONCLUSION
The ratio of orange peel to tamarind has an influence on the magnitude of the voltage and the strength of the electric current. The best bio-battery is when the percentage of orange peel to tamarind was 25%.
