Abstract

Gambir (Uncaria gambir Roxb.) dikenal karena kandungan tanninnya, terutama katekin, yang memiliki berbagai manfaat di bidang farmasi, makanan, dan kosmetik. Proses pengeringan gambir sangat penting untuk mengurangi kadar air dan menjaga kualitas ekstraknya. Namun, pengeringan yang tidak tepat, seperti suhu yang terlalu tinggi, dapat merusak senyawa aktif, mengurangi efektivitas, dan memperpendek umur simpan produk. Penelitian ini bertujuan untuk mengembangkan prototipe alat pengering gambir yang efisien, mampu mempertahankan kualitas senyawa aktif, serta meningkatkan daya saing industri pengolahan gambir. Metodologi yang digunakan meliputi pengukuran suhu secara manual dan simulasi menggunakan Computational Fluid Dynamics (CFD). Alat yang dirancang memiliki dimensi P x L x T sebesar 37 cm x 33 cm x 36 cm. Waktu yang dibutuhkan untuk mencapai suhu 38°C adalah 1080 detik. Hasil pengukuran menunjukkan error sebesar 0,04% pada posisi tempat wadah gambir (A) dan 4,9% pada bagian dekat pemanas (B).

Abstract

Corn (Zea mays) is a vital global commodity, yet traditional shelling remains a bottleneck for small-scale farmers, leading to high labor intensity and low productivity. This study aimed to design, construct, and evaluate the performance of a spiral-type corn sheller powered by a 1-HP electric motor. The performance was assessed through quantitative parameters (feeding rate, shelling capacity, and yield) and qualitative parameters (percentage of damaged and unshelled seeds). Results indicated a shelling capacity of 150 kg/h with a yield of 87%. The quantitative analysis showed 0.24% of unshelled seeds and 7% seed damage. Economic evaluation revealed a production cost of Rp 135.83/kg and a Break-Even Point (BEP) of 1,911.96 kg/year. The spiral-type mechanism effectively increases efficiency compared to manual shelling (±20 kg/h), making it a viable solution for small-scale agricultural industries.
