Abstract

Street vendors or traders who sell on the side of the road or who sell in city parks have lighting problems, because lighting is very influential on visitors or buyers. For areas close to people's homes, traders distribute lamps from one of the residents to turn on the lights by paying Rp.5,000. This study aims to help street vendors overcome the problem of lighting using alternative electric energy based on Thermoelectric Generator (TEG) type TEC-12706 with the side using fire generated by rice husk briquettes while the cold side using a 12V DC fan. This study uses several variations to light the lamp effectively and efficiently, including: variations in the number of cooling fans (without fans, 1 fan and 2 fans), variations of the peltier series (series, parallel and combination), variations in the number of peltiers (3 peltier and 6 peltier ). Based on the test results on the Thermoelectric Generator (TEG) the highest temprature difference is produced using 1 fan with 131.4 ℃, a circuit with 3 peltiers that produces the highest voltage, current and power using a series circuit with 6.84V, 0.28A, and 1.92W, and which is able to turn on a 12V 5 Watt DC lamp using 6 peltier to produce 13.5V, 0.55A, and 7,425W. So that with six peltier can turn on one fan and one 5 watt DC lamp.

Abstract

The development of the Vertical Axis Wind Turbine (VAWT) is still a challenge for several researchers in the world and in Indonesia. Due to the potential of the Indonesian coast generally has an average wind speed of 3-7 m / s which is classified as low wind speed and is very suitable for VAWT which operates at low wind speeds. Combining the 2 existing VAWT types is one of the development efforts on VAWT to improve the performance of these wind turbines. Hybrid VAWT Savonius-Darrieus can increase the coefficient of performance (Cp) where the maximum Cp of savonius is 30% while Darriues is 35%. There have been several researchers making the Savonius-Darrieus Hybrid VAWT prototype producing Cp above 35%, but this is still far from the ideal Cp of wind turbines around 59%. The combination variation of 2 types of VAWT still has the opportunity to be investigated with various variations in construction and variations in additional accessories. The research method that will be carried out is the prototype experimental method, with the design and prototyping stages. The prototype was tested at the Mechanical Engineering Laboratory of the Indramayu State Polytechnic by blowing the wind at a certain speed from the wind tunnel that had been prepared in advance. There were 11 samples prepared, namely 4 samples for 3 levels and 7 samples for 4 levels. There were 5 samples that reached a Cp value of 0.58 which was close to the ideal Cp value, but there was no increase in TSR in all samples.
