Cavite State University, Indang, Cavite, June 2019. Adviser:<br/>Engr. Kevin P. Titiwa.<br/>The study was conducted to design, fabricate, and evaluate black pepper thresher. The<br/>study evaluated the operating performance of the fabricated pepper thresher in terms of<br/>threshing capacity, threshing efficiency, threshing recovery, and power consumption. The device<br/>was fabricated using locally available materials. Its overall dimension is 148 cm x 76 cm x 97 cm<br/>(LxWxH). The device has eight major components, namely: hopper_ threshing cylinder. rotating<br/>shaft, blower. sieve assembly, prime mover, frame, and discharge chute. The working<br/>performance of the machine was evaluated using three treatments, considering rotating shaft<br/>speed of 580 rpm, 450 rpm and 375 rpm with three replications each and was analyzed using<br/>Complete Randomized Design. Duncans's Multiple Range Test (DMRT) was used for the<br/>comparison of treatment means. Results showed that the engine speed of 375 rpm had the<br/>highest threshing recovery of 97.41 percent, followed by 450 rpm and 580 rpm with a values of<br/>96.80 percent and 95.66 percent, respectively. The statistical analysis indicated that the<br/>threshing recovery of the rotating shaft of 375 rpm and 450 rpm were significantly different from<br/>580 rpm. Other parameters like threshing capacity, input capacity, threshing efficiency and<br/>power consumption for all treatments were found to be not significantly affected by the different<br/>rotating shaft.<br/>Based on the pepper thresher cost of P 29,955.00 covering materials and labor and a<br/>capacity of 62.61kg per hour, simple cost analysis of this study yielded a breakeven point of<br/>5,631.17 kg per year based on the cost of threshing pepper of P 4.95 per kilogram as the<br/>custom rate. Furthermore, the cost analysis also indicated a payback period of 0.60 years for<br/>the pepper thresher cost
