Abstract
Kebutuhan pengusaha jamu akan proses pengeringan yang cepat, efisien, dan konsisten menjadi hal penting dalam meningkatkan kualitas produk dan omset penjualan. Pengeringan manual menggunakan panas matahari yang lama berpotensi menurunkan kualitas bahan baku akibat pengeringan yang tidak merata, bahkan dapat menyebabkan pertumbuhan jamur. Selain itu, sistem pengeringan yang lebih baik juga dapat berkontribusi pada pemberdayaan petani dan masyarakat sekitar melalui peningkatan produktivitas. Penelitian ini bertujuan untuk merancang dan membangun alat pengering bahan baku jamu dengan sistem kendali otomatis. Sistem ini menggunakan pemanas berbasis PTC Heat Fan sebagai sumber udara panas, dilengkapi sensor temperatur RTD PT100 untuk mengukur temperatur aktual, dan dikendalikan oleh PLC Siemens S7-1200. PLC melakukan pengendalian On/Off terhadap PTC Heat Fan guna menjaga temperatur tetap pada nilai setpoint yang ditentukan. Data temperatur dan status komponen ditampilkan secara real-time melalui HMI Haiwell, sehingga proses pengeringan dapat dipantau dengan mudah. Dihasilkan sistem pengering otomatis dengan kontrol temperatur konsisten di 50°C dan overshoot maksimal 3%. Analisis efisiensi termal membuktikan kapasitas muatan 3 kg merupakan parameter operasional paling optimal dengan konsumsi energi spesifik terendah untuk jahe, temulawak, dan kunyit. Sistem ini terbukti secara signifikan mempercepat proses pengeringan dibandingkan metode konvensional (3 hari), menjadikannya solusi teknologi yang efektif. ==================================================================================================================================
The need for herbal medicine entrepreneurs to have a fast, efficient, and consistent drying process is crucial for improving product quality and sales revenue. Manual drying using sunlight, which takes a long time, has the potential to reduce the quality of raw materials due to uneven drying and can even lead to mold growth. In addition, a better drying system can also contribute to the empowerment of farmers and the surrounding community through increased productivity. This study aims to design and build a drying device for herbal medicine raw materials equipped with an automated control system. The system uses a PTC Heat Fan-based heater as a source of hot air, is equipped with a PT100 RTD temperature sensor to measure the actual temperature, and is controlled by a Siemens S7-1200 PLC. The PLC controls the PTC Heat Fan via an On/Off cycle to maintain the temperature at a predetermined setpoint. Temperature data and component status are displayed in real-time via a Haiwell HMI, allowing the drying process to be easily monitored. The resulting automated drying system maintains a consistent temperature of 50°C with a maximum overshoot of 3%. Thermal efficiency analysis confirms that a 3 kg load capacity is the most optimal operating parameter with the lowest specific energy consumption for ginger, temulawak, and turmeric. This system has been shown to significantly speed up the drying process compared to conventional methods (3 days), making it an effective technological solution.
