Abstract

Jagung (Zea mays L.) merupakan komoditas pertanian penting yang memerlukan proses pengeringan untuk menurunkan kadar air agar memenuhi standar mutu penyimpanan sesuai SNI 01-4483-1998. Penelitian ini menganalisis kinerja mesin pengering jagung pipil hybrid tipe greenhouse yang memanfaatkan kombinasi panas dari radiasi matahari dan gas heater.Penelitian ini diawali dengan perancangan dan pembuatan mesin pengering, kemudian dilakukan pengujian secara eksperimental menggunakan tiga variasi kecepatan udara blower, yaitu 5,5 m/s, 3,66 m/s, dan 2,7 m/s. Parameter yang diamati meliputi distribusi suhu, penurunan kadar air, dan efisiensi pengeringan. Hasil penelitian menunjukkan bahwa variasi kecepatan udara 3,66 m/s menghasilkan kinerja terbaik dengan suhu ruang pengering 50,2–56,5°C dan kadar air akhir terendah sebesar 13,8% dalam waktu 8 jam. Hasil ini lebih baik dibandingkan pengeringan tradisional yang membutuhkan waktu hingga 24 jam. Mesin pengering hybrid tipe greenhouse terbukti lebih efisien dan stabil serta tidak bergantung pada kondisi cuaca. Kata kunci: jagung pipil, pengering hybrid, greenhouse, gas heater, efisiensi. Corn (Zea mays L.) is an important agricultural commodity that requires a drying process to reduce its moisture content to meet storage quality standards according to SNI 01-4483-1998. This study analyzed the performance of a hybrid greenhouse-type corn kernel drying machine that utilizes a combination of solar radiation and a gas heater. The study began with the design and construction of the dryer, followed by experimental testing using three variations in blower air velocity: 5.5 m/s, 3.66 m/s, and 2.7 m/s. Observed parameters included temperature distribution, drying rate, moisture content reduction, and drying efficiency. The results showed that the 3.66 m/s air velocity variation produced the best performance, with a drying chamber temperature of 50.2–56.5°C and a final moisture content of 13.8% within 8 hours. These results were superior to traditional drying, which requires up to 24 hours. The hybrid greenhouse-type drying machine proved to be more efficient and stable, and was not dependent on weather conditions. Keywords: corn kernels, hybrid dryer, greenhouse, gas heater, efficiency.
