Abstract

In the process of processing cassava chips, especially chili chips made by the patumbak village community, ranging from stripping, washing, chopping, soaking and packing still use human labor and are done manually with simple tools. So that this problem can be overcome, the solution is to have designed and made cassava chopper machines. The purpose of this PKMS is to help solve the problems faced by small home industries with Appropriate Technology independently in the village patumbak, village. The implementation method begins by examining the technological and equipment deficiencies in the processing of cassava chips, especially the cassava chopper machine. During this time the process of chopping cassava before being fried into chips is done manually. The method used to achieve the PKMS goal is to make a cassava chopper machine in the village of Patumbak. The results obtained are that the PKMS activities have been completed by the team for 1 period of activity, the final result has been obtained the application of appropriate technology in the form of cassava chopper machines in partner villages and partners was greatly helped by these activities. From the activities that have been carried out the last questionnaire score that has been distributed to partner villages is the highest score influencing the results of understanding of the community or partners, where PKMS 2019 partners are satisfied and helped by the existence of the abdimas. The final result that has been obtained is the production of cassava chips increased by 50% when compared to before the team came to do PKMS activities, the condition of this improvement was seen after partners used cassava chopper machines from the PKMS team.

Abstract

The use of solar energy can be converted to thermal energy and can be used for cooking, drying agricultural products, and heating water. Solar energy developed and converted into thermal energy for cooking is the solar cooker. This study aims to compare the results of experimental research with ANSYS 14.0 simulation when cooking rice on a solar cooker. The type of solar stove used is a box type by adding mirror as a reflector, copper vessel as a PCM container, lug to hold the vessel's position during the cooking process, and aluminum vessel as a container for cooking rice. The result shows that the errors occurred between experimental and simulation at 10 minutes, 60 minutes, 120 minutes and 360 minutes are 1.15%, 0.84%, 0.79%, and 0.56 %, respectively Keyword: Solar Energy, Solar Cooker, Ansys Simulation

Abstract

The topic of this research is the engineering testing of a clothes drying machine by utilizing the waste heat condenser AC to dry clothes. The purpose of this study is to obtain the temperature and humidity of the average drying air in the drying chamber and to reduce the mass of the clothes to be dried. The heat output from the condenser is directly used to dry clothes on the dryer. The study was conducted within 30 minutes of the drying period. Clothing material used in this study is material with 100% cotton + polyester100% with a wet mass of 0.440 kg and a dry mass of 0.330 kg. The results obtained from this study were obtained mass of dry clothing in the 13th minute with a drying rate of 0.0085kg/s. The conclusion obtained that the use of condenser output for drying clothes is very beneficial for the utilization of wasted condenser heat. Keyword: AC Condensor, drying machine, clothes

Abstract

The rapid development of the refrigeration system, along with the rapid advancement of technology. Adsorption refrigeration cycle is currently being developed, especially in developing countries. Adsorption refrigeration cycle is very environmentally friendly. One component of this is the generator cooling machine. Type of generator used is a flat plate. The area of ​​adsorber is 0.25 m2 with a slab thickness is 1 mm. In this adsorber filled with activated carbon as much as 8 kg. The temperature of the water will decrease with decreasing temperature refrigerant in the evaporator. On the afternoon of the desorption process occurs adsorber receives heat from the lights and the refrigerant will flow into the condenser and melt in the evaporator, at night adsorber is cooled by the outside environment resulting in the adsorption process, the refrigerant will evaporate from the evaporator into the condenser and adsorber will be absorbed. The results of this study are vacuum adsorber temperature to obtain the absorption refrigerant refrigerant methanol at 200 0C and the temperature thermostat produces 123.43 0C adsorber temperature and methanol as refrigerant absorbs 6.25 ml/kg.

Abstract

Some researchers have conducted research on the effect of fuel magnetation on the performance of the engine it self. But of the many studies conducted, it has never done research on high-tech machines (high technology). So the writer is challenged to do testing on high-tech cars. This research was conducted to determine the effect of the magnetic field on fuel consumption on otto (gasoline) engines. The test method is carried out by attaching a magnet to the fuel line with a variety of magnetic placement positions in the fuel hose. The test results show the amount of fuel consumption in the magnetic position A (closest to the combustion chamber) has decreased by 20% at 750 rpm (idle rotation) followed by the amount of exhaust emissions reduced by 12.9%.
