Abstract
This research aimed to design and develop a ginger slicing machine with appropriate parameter control suitable for the Tid-Mai-Tid-Mue Community Enterprise. The study employed the principles of Design of Experiment (DoE) using a 2k Full Factorial Design to investigate the factors affecting the machine's performance. The experimental results revealed that the coefficient of determination (R-sq) was 99.61% and the adjusted R-sq was 98.23%, indicating excellent model fit. A two-tailed hypothesis test was conducted with the null hypothesis H0: = 78.63 and the alternative hypothesis H1:
≠ 78.63. The P-value was 0.809 at a significance level of 0.05 indicated that the results followed a normal distribution and met statistical validity requirements. A performance evaluation comparing manual slicing with the developed ginger slicing machine showed that manual labor required 486 seconds to slice 3 kilograms of ginger, whereas the developed machine achieved an 80.38% reduction in processing time, completing the same task in approximately 95 seconds. Implementation of the machine significantly reduced labor workload, production costs, and operator fatigue while increasing productivity. Additionally, it contributed to the enhancement of herbal product processing to better meet market and community enterprise demands.
