ABSTRACT In this day and age, many roads are already using Solar Public Street Lighting (PJUTS). PJUTS is a Solar Power Plant (PLTS) application off-grid for street lighting. Inayah Islamic School plans to build PJUTS on the road in its school complex. The size of the road is small and sourced electrical energy from the sun, it is one of the foundations of research. This study aims to design s…
ABSTRACT Portable coastal radar is an important device for monitoring the security of the borders of Indonesian waters. In the 2019 presidential election debate, President Jokowi said that there were already 11 maritime radar points installed in several parts of Indonesia. This amount is still not enough to cover Indonesian waters as a whole, especially in border areas. Radar consists of sever…
ABSTRACT Chicken farms are distinguished between broilers and laying hens, in broilers the cages are made large with a large number of chickens. Place for chicken feed is a container used as a place for feeding chickens. There are several factors that can be monitored such as temperature and humidity in the farm room and automatic feed which can be set manually and real time clock on the Blynk…

ABSTRACT The ultimate goal of this project is to create a dynamic braking system for a three-phase cage rotor induction motor. This can be done with four circuit models, one of which is dynamic braking using direct current injection. Direct current injection is obtained from an uncontrolled full-wave three-phase rectifier circuit originating from a single-phase transformer. This single-phase t…
ABSTRACT One of the most effective ways of controlling the speed of an induction motor is to control the frequency and voltage of the source. This can be realized by designing an inverter that produces voltages and frequencies that can be controlled. The inverter design in this study uses the SVPWM modulation technique combined with a PI controller with specifications adjusted to the load, is …
