Abstract: Produksi kentang di Kecamatan Modoinding, Kabupaten Minahasa Selatan cukup tinggi saat panen raya, tetapi hasil panen melebihi permintaan pasar. Selain enyakit fusarium pada kentang memaksa panen dilakukan sebelum 90 hari. Kentang yang kaya karbohidrat dapat diolah menjadi tepung kentang, sehingga dibutuhkan unit pengolahan tepung. Proyek ini bertujuan merancang proses pembuatan tepung kentang secara rinci, menguji kinerja tepung dalam meningkatkan mutu produk pangan, mengevaluasi karakteristik tepung pada produk turunan, dan merancang alat pengeringan energi yang efisien. Metode yang digunakan mencakup desain proses pembuatan tepung, uji kinerja tepung pada produk mie komposit pati sagu dan tepung kentang, serta desain alat drum dryer untuk pengeringan dengan penggunaan energi yang lebih. Hasil uji menunjukkan bahwa mie komposit dengan konsentrasi 60% tepung kentang dan 40% sagu menghasilkan mie yang berwarna kuning dengan tekstur kenyal, elastis, dan waktu pemasakan cepat. Kadar proksimat tepung kentang adalah air 7,4%, protein 10,4%, lemak 0,4%, abu 0,8%, dan karbohidrat 80,4%. Drum dryer dipilih karena efisiensi penggunaan energinya lebih tinggi, dengan kapasitas 31 kg/jam untuk mengeringkan 600 kg bahan dengan diameter 3,6 meter dan tinggi 1,8 meter. Perubahan viskositas gliserol sebagai pemanas pada fluida yang drastis dengan perubahan suhu memiliki dampak yang signifikan pada perpindahan panas.
The potato production in Modoinding District, South Minahasa, was quite high during the harvest season, but it exceeded the market demand. Fusarium disease also required early harvest within 90 days. The carbohydrate-rich potatoes could be processed into potato flour, necessitating a flour processing unit. The project aimed to design a detailed process for making potato flour, tested its performance in improving food product quality, evaluated flour characteristics in derived products, and designed an energy-efficient drying equipment. The methods included flour production process design, performance testing on composite noodle products made from sago starch and potato flour, and designing a drum dryer for efficient drying with less energy usage. Test results showed that composite noodles with 60% potato flour and 40% sago starch had yellow color, chewy and elastic texture, and quick cooking time. The proximate composition of potato flour included 7.4% water, 10.4% protein, 0.4% fat, 0.8% ash, and 80.4% carbohydrates. The drum dryer was chosen for its higher energy efficiency, with a capacity of 31 kg/hour to dry 600 kg of material, with a diameter of 3.6 meters and height of 1.8 meters. The significant impact of glycerol's viscosity changes as a heating fluid with temperature variation was observed on heat transfer.
