Abstract

The energy produced by the Sun is heat energy and light energy. One of the uses of solar thermal energy is the thermoelectric generator (TEG). This research on solar thermoelectric generators uses 2 variations of cooling media, namely water cooling media and soil cooling media with a series series for thermoelectrics, while what will be analyzed is the amount of power from both tests and the ability the solar collector absorbs the sun's radiation heat. The test results and calculations determine the calorific value of solar radiation that is absorbed by the collector. That is 25,265 Watts. As for the results of testing the cooling media, the best results were obtained for the water cooling media with the greatest value at 0.04 Watt.

Abstract

The Badan Pusat Statistik (BPS) data for 2021 shows that the total rubber production in Indonesia reached 2.877,90 tons. The high amount of rubber production will accompany many by-products, such as rubber seed shells and fruit shells. These materials have not been widely used for commercial purposes. This research will use rubber seed shells and fruit shells as brake pad filler. These materials are expected to replace brake pads that still contain asbestos, even though asbestos harms human health. Brake pads are manufactured using the cold press method, which has a composition is 60% epoxy resin, 35% filler, and 5% nylon fiber. The observed characteristics of the organic brake pad are mechanical, tribological, and thermal behavior using rubber seed shell and fruit shell fillers. This research conducted several results. Both friction coefficient values have met the performance values of the standard commercial brake pad material. The rubber seed shell has better wear resistance as filler in brake pad material than fruit shells. The type of wear for rubber seed shells is abrasive wear. The thermal analysis shows that the decomposition temperature of the rubber fruit shell is higher than the rubber seed shell.

Abstract

Friction welding is a type of welding that is used for a variety of materials. Friction welding is a method of joining two materials by swiping them together until they reach some of the melting points of the materials to be joined, then applying constant pressure. Aluminum and copper are the materials to be joined in this study. Using rotational speed and contact surface roughness variations. The purpose of this research is to determine the mechanical properties of friction welding results between aluminum and copper. The speed settings are 1230, 1500, and 2500 rpm. Use sandpaper grades #100, #800, and #1500 to achieve different levels of surface roughness. According to the results of this study, the rotational speed with the highest tensile strength and hardness values is 1230 rpm, namely 59.6 MPa and 54.6 HVN (Al), 112.1 HVN (Al) (Cu). In terms of surface roughness variations, the surface roughness using grade #1500 sandpaper has the highest value, namely 54.18 HVN (Al), 112.1 HVN (Cu). And #100 sandpaper with a value of 52.48 Mpa. The results of the microstructure test in the weld joint area at a magnification of 1000x indicated that the friction welding of aluminum and copper was successful, as evidenced by the diffusion of aluminum and copper in this area.

Abstract

Thermal spray coating is a material protection process by depositing the coating material on the substrate material. Process parameters such as spray-off distance, surface roughness, and substrate preheat temperature, spray time, voltage, and arc current greatly influence the mechanical and tribological behavior. Selection of appropriate process parameters and coating materials must be carried out to obtain a coating that meets the design requirements. The coating method used is electric arc spray with parameters: spray-off distance of 200 mm, compressor air pressure of 7 bar, voltage of 32 volts, and layer thickness of 1 mm. At the same time, the independent variables are arc currents: 159, 185, and 299 amperes. The substrate material is AISI 1045 steel, PMET 885 intermediate material, and PMET 720 coating material. The tests carried out were observing the microstructure, hardness, wear rate, and corrosion rate. This research shows that the higher the arc current, the better the coating quality. At an arc current of 229 amperes, it is known that the hardness, the wear rate, and the corrosion rate are 398.10 VHN, 8.96 x 10-8 gram/mm2.s, and 0.8911 mpy, respectively. This research's contribution is to provide a reference on the influence of the arc current of the electrical arc spray coating process on the tribological behavior of the surface layer so that suitable for the desired application.

Abstract

Bamboo is a natural material that is widely found in South Banten. Using bamboo as an alternative material for manufacturing brake pads is interesting to research. Bamboo resistance to attacks of organisms is so low that it is necessary to give initial treatment. Preservation of bamboo sticks is done by soaking them in seawater. This immersion is determined for 15 and 30 days. The comparison of the composite constituent composition is 30% bamboo fiber, 28% bamboo particles, 2% zinc, and 40% epoxy resin. Compaction pressure is carried out by 400 kg/cm2 for 10 minutes. The sintering process is carried out at a temperature of 150 °C for 60 minutes. From this research, it is known that the immersion of bamboo stems in seawater tends to decrease the hardness and the wear rate of composites.
