EFISIENSI PRODUKSI UMKM KERIPIK DENGAN MENGGUNAKAN ALAT PENGIRIS UMBI-UMBIAN DENGAN MATA PISAU BERPUTAR

Abstract

The manual processing of cassava (singkong) into thin slices for chip production is labor-intensive, time-consuming, and yields inconsistent slice thickness. This study presents a low-cost appropriate technology (TTG) solution: a simple cassava slicing machine powered by a small electric motor (dinamo) implemented in Candiwatu Village, Pacet, Mojokerto. The machine’s design, fabrication, and community training were carried out during a student service project (KKN). Performance evaluations show that the motor-driven slicer significantly reduces slicing time (upto 3–4 times faster than manual cutting) and operator fatigue, while producing uniform slices The device uses locally available materials (steel frame and stainless- steel blades) and runs on a 125–250 W AC motor, consuming relatively little electricity. Field trials indicate clear benefits for small-scale processors: higher daily throughput (approx. 12 kg/hour capacity), improved product quality, and potential income gains. These findings demonstrate that the motorized cassava slicer is feasible for village-level food entrepreneurs, embodying the TTG principles of simplicity, economy, and ease of maintenance.
