Abstract

Cassava (Manihot esculenta) is an important source of carbohydrates in Indonesia, which is often processed into various value-added products, such as cassava chips. This research aims to analyze the effect of variations in the rotation speed of the motor on the chopping machine on the results of chopping cassava, with the parameters measured including chop thickness, production capacity, energy consumption and machine efficiency. Tests were carried out using an electric motor with rotation speeds of 307.3 rpm, 403.6 rpm and 553.3 rpm. The research results showed that increasing the motor rotation speed produced cassava chops with a thinner thickness, namely from 1.35 mm at a speed of 307.3 rpm to 0.65 mm at 553.3 rpm. Production capacity increased from 103.7 kg/hour at the lowest speed to 129 kg/hour at the highest speed. However, energy consumption and operational costs also increase significantly, with optimal efficiency achieved at a speed of 403.6 rpm. The conclusion of this research is that the motor rotation speed influences the quality and quantity of chopped cassava results, as well as the efficiency of the machine. Motor speed adjustments must take into account production needs, both in terms of chopped product quality and energy efficiency.
