Uji Berbagai Pulley Alat Pemarut Tipe Silinder pada Komoditas Umbi Talas (Colocasia esculenta L.)

Abstract

Taro tuber, Latinly known as Colocasia esculenta L, is a common root crop found all over the world. Complex carbohydrates, dietary fiber, and a number of essential minerals and vitamins can all be found in taro tubers. Post-harvest processing of taro tubers can be done by grating them, so that the results of the grating process can be made into various delicious and high-value processed food ingredients. The purpose of this research is to test the effect of various pulley diameters to get the best diameter in obtaining the maximum taro tuber grated results on a cylindrical type grater. With the change of pulley, it is expected to increase efficiency and productivity in the process of grating taro tubers. This study used a non-factorial complete randomized design. The pulley diameters used were 2 inches (P1), 4 inches (P2) and 6 inches (P3). In this study, the best pulley in treatment 3 pulley is 6 inches. The results of this study indicate that the largest effective tool capacity (172.47 kg/hour) in (P3) with a pulley size of 6 inches, the largest yield (89.97%) in (P3) with a pulley size of 6 inches and the largest percentage of material lost (23.73%) in (P1) with a pulley size of 2 inches.
