Abstrak Industri jamu, sebagai bagian dari warisan budaya dan tradisi kesehatan masyarakat Indonesia, terus berkembang dengan memanfaatkan berbagai rempah seperti jahe, kencur, dan temulawak. Proses pengolahan rempah, terutama pengeringan, merupakan tahap kritis yang mempengaruhi kualitas dan daya simpan produk akhir. Di Kampung Jamu Wonolopo, Semarang, proses pengeringan masih dilakukan secara tradisional, yang rentan terhadap variasi cuaca. Penelitian ini bertujuan untuk merancang sistem kendali alat pengering empon- empon berbasis PLC dan HMI yang dapat meningkatkan efisiensi dan konsistensi proses pengeringan. Hasil penelitian menunjukkan bahwa integrasi PLC dan HMI memungkinkan otomatisasi dan kontrol yang stabil dengan metode PID, menghasilkan kadar air rata-rata 9% dalam waktu pengeringan sekitar 8 jam pada suhu 65 °C, dengan konsumsi energi 9 kWh per siklus. Kata Kunci: Jamu, Pengeringan, PLC, PID, Suhu Abstract The herbal medicine industry, as part of Indonesia's cultural heritage and traditional community health practices, continues to evolve by utilizing various spices such as ginger, aromatic ginger, and turmeric. The spice processing stage, particularly drying, is a critical phase that affects the quality and shelf life of the final product. In Wonolopo Herbal Village, Semarang, the drying process is still carried out traditionally, making it vulnerable to weather variations. This study aims to design a control system for a spice dryer using PLC and HMI to enhance the efficiency and consistency of the drying process. The results indicate that the integration of PLC and HMI enables automation and stable control through the PID method, achieving an average moisture content of 9% within approximately 8 hours of drying at 65 °C, with an energy consumption of 9 kWh per cycle.
