The chopped results of solid medical waste in the form of p…
ABSTRACT Indonesia is located in the equatorial region, so it has a longer sunlight exposure time. However, the problem faced from this solar energy is the storage of energy that has been collected by the collector. So far, the existing forms of solar energy storage are hot water tanks, rocks, phase change materials, and solar ponds. Solar ponds are salt water ponds that are capable of storing…
ABSTRACT One of the problems in drying agricultural products is the limited solar heat during the rainy season. Therefore, it is necessary to find other alternatives to obtain heat energy. One of them is by utilising the working principle of heat pumps with the help of solar collector or commonly referred to as Solar Assisted Heat Pump (SAHP). This research designs a lemongrass plantain dryer …
ABSTRACT Boilers are closed vessels primarily used for the generation of steam from air by burning fuels, namely, coal, gas, nuclear, etc. Energy auditing is the process of evaluating energy utilization, identifying energy-saving opportunities, and recommending efficiency improvements for energy sources and energy users in order to conserve energy. Based on the preliminary data collection on t…
ABSTRACT Coins are used in everyday life in various places such as in banks, supermarkets and automatic weighing machines. So, there was a basic need to automate coin counting and sorting. For these machines it is necessary to recognize coins very quickly and accurately, because further transaction processing depends on this recognition. Banks use money counting machines to count money. It can…
ABSTACT Lubricant is something that plays an important role in maintaining friction used in every vehicle and engine, if talking about used lubricating oil material, then it not only deals with the oil itself, but also the oil container and filter, all three if disposed of carelessly will cause environmental problems. The working principle of the used oil distillation tool is to take advantage…
ABSTRAK Mixing machines for plastic pellets and dyes available on the market are relatively expensive, the results of mixing the raw materials are uneven and cleaning the tool before use for other colors is less practical. The design stages include identifying the problem, making the working concept of the tool, then selecting the type of propeller, shaft, rolling bearing, frame, power transmis…
The rotary bending fatigue test equipment has been designed and manufactured as a fatigue testing tool for metal materials, especially steel.
