Abstract

Previous research has discussed tea drying machines with energy sources from PLN. Tea drying machines with refrigerant systems require large electrical energy costs. The electrical energy produced by a tea drying machine is proportional to its performance and cost. This research designed a 400 WP solar cell (PLTS) as a power supply for drying tea leaves. PLTS was combined with a PLN electricity source. Hybrid energy from PLTS and PLN was designed to maximize the use of electrical energy used by drying tea leaves. PLC and SCADA were used to monitor input current, output voltage, and output power. PLC and SCADA can optimize load requirements. When the solar radiation received by the solar panels was not optimal, PLN was able to back up load requirements. The average voltage produced by hybrid energy was 232.4 V. Hybrid energy was able to save power usage of 108.92 W or 12.8% of the load power requirements

Abstract

Transforming common water hyacinths into handicrafts is a viable business opportunity in several regions across Indonesia. One of the crucial processing stages in producing these handicrafts is flattening, which reduces the plant material to approximately 0.2 mm in thickness to ensure optimal weaving quality. The objective of this research is to design an automatic water hyacinth harvesting machine that uses an off-grid solar power plant as its primary energy source. The automation system on this machine uses a Programmable Logic Controller (PLC) as the control system and Supervisory Control and Data Acquisition (SCADA) as the interface and monitoring system. The designed water hyacinth flattening machine increases production capacity to 834 grams in 15 minutes. The size of flattened water hyacinths was 0.2 mm, following the flattening roller setting. The machine's average power consumption is 249 W, which the solar power plant system can supply for approximately 1.5 hours.
