Abstract

Conventional clove drying still depends on weather conditions, making the drying duration difficult to control. This study aimed to design a greenhouse-based clove dryer powered by a Solar Power Generation System (PLTS) with temperature control using an ESP32 and to evaluate its performance compared with conventional drying. The system employed a DHT22 sensor, heater, circulation fan, exhaust fan, automatic sieve rack mechanism, PZEM-017, and ThingSpeak for Internet of Things (IoT)-based monitoring. Testing was conducted using 5 kg of fresh cloves with an initial moisture content of 70%. The results showed that the dryer reduced the moisture content to 12.5% within 32 hours or 3 days, while conventional drying required 40 hours or 4 days and resulted in a final moisture content of 12.9%. The proposed dryer reduced the drying time by approximately 20% and achieved the target moisture content, although temperature stability and heat distribution still require further optimization.
