Abstract

Electric bicycles are bicycles that are battery powered and driven by a motor. Electric bicycles can utilize more than one energy source, namely generator energy and solar energy to supply the battery, which is called hybrid energy. Battery charging is limited when it is full to prevent overcharging. Battery charging can be done using several methods, one of which is the Constant Voltage (CV) method. The stage for synchronizing hybrid energy sources is to condition the voltage of both hybrid sources so that the same value is achieved. Conditioning over charge uses an auto cut-off circuit which can cut off the source current if the battery is full, indicated by a Light Emitting Diode (LED). Research shows that battery charging by relying on a boost converter to synchronize the two sources can work very well. The boost converter voltage does not accumulate because both boost converters are installed in parallel. The auto cut-off circuit can prevent overcharging the battery by utilizing a zener diode and relay.

Abstract

Mina rice cultivation is an integration of fish and rice cultivation in one location, which requires efficient time and energy management. Providing food and regulating water conditions are important aspects in this cultivation. Pond water temperature and pH have a significant effect on fish welfare, so monitoring both is very important. This research aims to design a prototype for controlling tarpaulin pond media for the mina padi cultivation system. The research method involves collecting data from various sources and studying the planned automated system of tools. Arduino Uno is the main component as a system regulator or controller, equipped with ultrasonic, temperature and pH sensors, as well as RTC to regulate the feeding schedule. Measurement data will be displayed via LCD to monitor pool conditions in real-time. Detailed design is carried out to ensure that the equipment meets the needs in cultivating mina rice.
