The problem that arises from the use of PV is that the Output power often does not reach the actual maximum power, especially in conditions of low solar radiation. Solar panels have their own optimal operating point called MPP. The characteristics of this MPP will change depending on sunlight and temperature. MPPT is used to make the solar cell operation point work at the MPP point. In this stu…
The government's main policy direction regarding national energy is energy conservation to increase the efficiency of energy use and utilization (demand side) and energy diversification to increase the share of new energy and renewable energy in the national energy structure (supply side). This process includes an energy audit, which is a method for calculating the energy consumption level of a…
High-voltage plasma generation is a type of voltage that is widely utilized in environmentally friendly technology. High-voltage plasma can be designed using a flyback transformer full bridge inverter topology using MOSFET as a switching device. The MOSFET is controlled by an IC TL494 control circuit connected to a 15-volt DC voltage source. The high-voltage side of the flyback transformer is c…
One of the technological developments in the transportation sector that can be found is the parking service system. Currently, parking in a mall still uses parking attendants who only control each vehicle that enters and also do not pay attention to the capacity of the parking area. So driver errors often occur due to lack of information on parking capacity in a parking area. The solution to th…
The ever-increasing need for electrical energy has encouraged energy providers such as PT PLN (Persero) to offer prepaid kWh electricity services, providing flexibility for users in managing energy usage. However, the current electricity token Input system is still manual and limited by distance. This research aims to find a solution by designing an IoT-based Keypad pressing device that can be …
Traffic lights is a traffic control tool at intersections and are useful for regulating smooth traffic at intersections to avoid traffic jams. Current traffic lights still have a weakness, namely the fixed duration of the light timing at each intersection. This weakness is what causes traffic jams that often occur at road intersections. Congestion also occurs at certain hours, for example when …
