Uji Kecepatan Putaran pada Mesin Perajang Temulawak (Curcuma zanthorrizha L.)

Abstract

Temulawak (Curcuma zanthorryza L.) is often found in tropical forests. Temulawak also reproduces on moorland around settlements, especially on loose soil, so that the rhizome fruit easily grows large. To make processed ginger, a machine is needed to speed up the chopping process, which is called a ginger chopper machine. The aim of this research is to test the rotation speed of the Temulawak chopping machine with the calculation parameters of the effective capacity of the tool, yield, percentage of wasted material and economic analysis. The Temulawak chopping machine has 3 engine rotation speed treatments, namely 800 rpm, 1000 rpm and 1200 rpm. In this study, the average effective capacity of the tool was found to be 43.20kg/hour, 49.49kg/hour and 58.48kg/hour. The average yield values obtained from testing were 0.95%, 0.94% and 0.95%. The average results of wasted material are 0.01%, 0.03% and 0.02%. The economic analysis of this machine has fixed costs of IDR 184,000
