Analisis Karakteristik Kelistrikan Campuran Belimbing Wuluh dan Jeruk Lemon Sebagai Sumber Listrik

Abstract

Electrical energy is one of the primer facilities used in every activity. Almost all the existing facilities use electricity. This is inversely proportional to the depleting energy source. The solution to this problem is to replace fossil fuels with renewable energy sources. Renewable energy is a source of energy that can be recycled and does not damage the environment. One type of renewable energy is to use the electrolysis method. Electrolysis Method is one of the renewable energy sources. This method uses electrolyte solution which can be found in sour and runny fruit such as lemon (Citrus Limon L.) and Wuluh Star fruit (Averrhoa bilimbi). The study was conducted in a laboratory by mixing the results of the juice of the two fruits with different compositions. The mixes are placed in the arcs (a mixture container to test the electrical properties) and then tested using a multimeter every 2 hours for 24 hours. The results are described in graphical form. The average power of each mixture is, C1 = 2.2mW, C2 = 4.7mW, and C3 = 8.5 mW and based on the graph, each mixture has decreased voltage and current. Even so among the three mixtures, the third mixture has a better electrical power value than the other two mixes. This shows that the higher the acidity of a solution the higher the electricity produced.

Characteristic of Ceremai Fruit Electrical Properties as Electrolyte Solution in Galvanic Cells

“…The circuit is equipped with a Casey 2 Logger Pro type Laybold-524 002 with a voltage sensor with an accuracy up to 1 nV to measure the voltage value and an electric current sensor with an accuracy up to 1 nA to determine the value of the electric current generated by the galvanic cell. The value of electric power is obtained using the equation 2 (Didik & Wahyudi, 2020;Ningsih;Sulaiman et al, 2020).…”

“…Alternative energy is an energy source that is produced from materials that have never been used before. Currently, research on alternative energy is increasingly being carried out, especially alternative energy sourced from nature and can be renewed (Sulaiman et al, 2020). Various types of alternative electrical energy have developed including electrical energy from solar cells.…”

“…Basically, electrical energy can be obtained from various sources including fruits and vegetables, especially fruits and vegetables that contain a lot of citric acid (Sulaiman et al, 2020). Acidity in some types of fruit is able to produce electrical energy because it is an electrolyte.…”

“…Spontaneous redox reactions can result in the electrical energy. A galvanic cell consists of two different metals used as anode and cathode and an acidic electrolyte solution as a source of ions that produce an electric current (Lacina et al, 2018;Mertin et al, 2021;Shevtsof et al, 2021;Sulaiman et al, 2020).…”

“…Previous studies have confirmed that the acidic properties of fruit can be used as an electrolyte solution in galvanic cells. Sulaiman et al, used a mixture using a mixture of star fruit and lemon as an electrolyte solution in several galvanic cells which produced a maximum voltage of 5.73 volts (Sulaiman et al, 2020). Suciyati et al, used oranges and orange peels as electrolyte solutions and produced a maximum voltage of 0.986 volts (Suciyati et al, 2019).…”
