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.
