Potential heat is wasted from AC condenser (Air Conditioner) is currently only a waste of energy that is exposed to the surrounding environment. This waste heat has the potential as an energy source that can be used for the drying process. If seen from the potential heat generated by a condenser that is quite large (greater than 3 times the electric power of the compressor and hot air temperatu…
One of the crops which is mostly planted in the country of Indonesia is a rice plant. One of post-harvest process is the drying process. Growing technology in agriculture and food, created grain drying technology better and more efficient than conventional drying, on of them with a mechanical dryer. Mechanical dryer basically done using heat from combustion and air is blown through heater or di…
The Micro Hydro Power Plant (PLTMH) which is very often used today is the Cross Flow Turbine. The reason is because of the high level of efficiency using low pressure and speed, the flow of water flows through the entrance of the pipe and is regulated by the guide vane and guide in to the turbine blade rotation. After the water has passed the turbine blade rotation, the water is in the opposite…
In Indonesian Corn is an abundant crop. Postharvest handling aims that corn can be stored for a long time. One method with conventional drying. The weakness of this method depends on the weather and requires a large place for drying. One effort to overcome the disadvantages of conventional drying is by using a dryer made from rice husk. The purpose of this study was to determine the effect of t…
Biomass furnace is a medium commonly used to establish burning reactions, then the heat produced is utilized for cooking purposes. The design of biomass furnace used by the community is still very simple so that the combustion efficiency is still low, which is only ranging from 5 to 10%. The design of the furnace in this research is to modify the primary air inlet and the altitude variation of…
The Tesla turbine is a machine using alternative energy. The energy can change the potential energy of the fluid into mechanical energy by using disk arranged sequentially on one axis of the shaft with gap and the number of the disk which is specified. The Tesla turbine is a turbine that utilizes the effects of fluid blocked between gap results from viscosity, thus utilizing the effect of bound…

Utilization of water energy is basically the use of potential energy and kinetic energy, the kinetic energy of water flow which is a transformation of gravitational potential energy is used to drive a turbine or windmill, Tesla turbines have a simple design but have considerable efficiency in their utilization. This study uses two methods, namely the experimental method and the literature stud…
Drying is one way of post-harvest handling to extend the shelf life, especially of agricultural crops. In general, post-harvest drying is only done naturally by drying using heat from solar energy or commonly called conventional drying. In the research on the grain drying process using a fluidized bed drying method in which the drying device was modified by the addition of heat exchanger pipes.…
Water energy is a renewable energy that can be used as a power plant. Water flow energy which can be used to drive a wheel or turbine. Savonius turbine is suitable for utilizing relatively low water flow energy, because savonius turbines have a good self starting. So that there is the potential to utilize irrigation as a power plant. The purpose of this study was to determine the effect of var…
