Abstract

A thermoelectric generator is an electrical generator device that converts heat energy into electricity directly based on the Seebeck effect method, namely if two different metals are connected at one end, then given a different temperature at the connection, there will be a voltage difference at the other end. with the other end, this study uses peltier tec-12706, the purpose of this study is to determine the effect of the temperature difference between the cold side and the hot side of the varied heatsink/fin designs. This thermoelectric component is coated by a thin ceramic that contains a bismuth telluride rod inside. When in supply the dc voltage is 12volt-15volt and the current is 2-5a. The cooling box material is covered with styrofoam, with a heat sink in the form of a heat sink fan. Variations are made on the amount of thermoelectric used. Data retrieval is done by installing a voltmeter, ammeter and thermocouple in a predetermined position then each measuring instrument will display the data. The data is then processed using the Microsoft Excel program which can produce graphs. With the form of a graph, discussion and conclusion can be done easily

Abstract

Oil, natural gas, and coal are non-renewable fossil energy sources. The limited availability of non-renewable fossil fuels has prompted countries worldwide to develop technologies that harness energy from renewable sources. One of these renewable energy sources is biofuel, which includes bioethanol and biodiesel. Currently, the Co-Pyrolysis method has been widely developed for waste processing. The Co-Pyrolysis method aims to extract energy content from a mixture of raw materials. The varying percentage of raw material mixtures can significantly influence the resulting products. Obtaining the characteristics of raw materials, the differences in temperature distribution graphs for each percentage of the raw material mixture, and achieving optimum product yield are the objectives of the Co-Pyrolysis process. Based on the data from the heating process, it has been found that an excellent product can be obtained from heating a mixture of TKKS (30%) and PS (70%) at 500 °C for 1 hour, resulting in a product yield of 68%.
