In rocket stove, wood is burned in a simple combustion chamber. This combustion chamber is connected by chimneys and air holes. Several studies have been carried out to utilize the heat generated by combustion of rocket stove, namely thermoelectric generators. Thermoelectric generators are electrical generator devices that convert heat energy or temperature differences into electrical energy using a phenomenon called the seebeck effect. The thermoelectric generator used in this study is TEG SP1848. How this tool works is a compilation of combustion occurs on a rocket stove then the copper pipe which is wrapped around a rocket stove flowed by wateralso rises in temperature, and the circulation of water from the chamber passes through a copper pipe, within 30 minutes the water in the chamber reaches 90°C ± then it is done from the power generated by the TEG connection then the test is done by loading a resistor of 1kΏ-10kΏ the highest generator efficiency values obtained at the 5k ohm resistor reached 5.38% of the left TEG. For TEG the right side of generator efficiency tends to be stable. The highest value of the right-side TEG generator efficiency is obtained at 0.48% at 2k ohm resistance.

Electrical vehicle is a vehicle that uses one or more electric motors or traction motors as its driving force. Electric vehicles first appeared in the mid-19th century, when electricity was chosen as the propulsion in vehicles. At that time, electric vehicles offered greater comfort and easier operation than gasoline-powered cars. However, since the advancement of the internal combustion engine, the existence of this technology has been less competitive. The decline in the use of vehicles with electric power at that time was due to the quite expensive price, but on the other hand EV has the advantage of a very good level of environmental friendliness, because there is no exhaust gas coming out of the engine. To get a power source, EV uses electrical energy stored in the battery, because it is necessary to charge the battery embedded in the vehicle before using it. Without realizing it, the use of motorbikes has negative things including incomplete combustion results, resulting in air pollution and on the other hand the materials to operate it are also running out and running out. The electric motor can be the answer to various problems that exist today and even in the future, because the electric motor has better efficiency than the combustion motor. The disadvantage of an electric motor is that the price is quite high when compared to a combustion motor, but on the other hand, such as the maintenance and efficiency of the energy source of an electric motor, it is far superior. In addition, with the electric motor, it can overcome the problem of natural resource fuel, which is increasingly shrinking.

The dynamometer is equipment that functions to measure the power and torque generated by the internal combustion engine. The dynamometer has a way of working, namely absorbing mechanical energy generated by the engine at the engine output shaft rotation. The types of dynamometers is the electric dynamometer, eddy-current dynamometer, water brake dynamometer, prony brake, and fan brake. This study aims to obtain a dynamometer design that is simple and has relevant measurement accuracy. This water brake dynamometer is designed to withstand / test engine power up to 13 horsepower. The transfer of power from the engine to the dynamometer is done by adding a shaft and jaw coupling. Torque measurement will use load cell, meanwhile to measure revolutions per minute using proximity sensor. The test will be carried out by measuring the 118cc engine power with the SAE J1349 test method.
