Abstract

This study aims to determine the effect of combustion temperature on the microstructure and particle diameter of the average silica ash of cocoa shells, and to determine the effect of combustion temperature on the silica content of cocoa shell ash. The method used is experimental through a quantitative approach. The basic material used is cocoa husk (Theobroma cacao) with combustion temperatures of 450, 550, 650, and 750 oC. The tests used to determine the microstructure and silica content of cocoa husk ash were SEM and XRD after which they were analyzed again using Digimizer Software and X-Powder Software. SEM results based on microstructure indicate the occurrence of agglomeration in the cocoa ash silica sample, and it is known that the particle diameter size of sample A = 1,6916 µm, sample B = 0,7824 µm, sample C = 0,7809 µm, and sample D = 0,7173 µm. Based on the XRD results, it can be seen that the silica contained in sample A = 34,8%, sample B = 49,0%, sample C = 65,0%, and sample D = 70,6%. Based on the SEM results, the best results are in the sample which has the smallest size, namely sample D with a particle diameter of 0,7173 µm and based on XRD results the best results are in sample D with the highest SiO2 content of 70,6%. So that the combustion temperature affects the results of SEM and XRD where the effective temperature in the manufacture of cocoa shell ash silica is 750 oC.

Abstract

The purpose of this research to analyze the effect of increasing the volume and fermentation time on the bio-battery electricity of pineapple juice. Bio-battery prototype design with acrylic size 12x5x7 consisting of 6 pair of Cu-Zn electrodes. The volume of solution used was 150 ml, 200 ml, and 250 ml. The pineapple juice solution was fermented for 3 days, 5 days, 7 days, 9 days, and 11 days. A pH meter is used to measure the acidity of the solution. Electrical measurements such as electric current and voltage with a digital multimeter. When the solution is fermented for 11 days, the maximum electrical value is obtained with a volume of 200 ml which was 4,84V; 14,58mA; and 70,57mW. In this study, increasing the volume of the solution did not have much effect on the electrical voltage. Pineapple juice bio-battery is used to turn on the red LED for 2 hours with a voltage drop of 0,01-0,04V. After reaction, the Copper was thickened due to the oxidation with the Zinc.
