| Summary, etc. |
The Philippines, as the second-largest producer of coconut products, utilizes every<br/>part of the coconut plant for sustainable industrial use. One such application is the<br/>production of broomsticks from coconut leaves by extracting the midribs. This study<br/>developed a semi-automatic coconut broomstick-making machine to improve production<br/>efficiency and reduce the limitations of manual labor. The machine features a dual cutter,<br/>rubber rollers (in place of abrasives), feeder guide, dust collector, and chain and gear<br/>transmission systems. The machine was evaluated using fresh and dried coconut leaves to<br/>measure production rate, de-leafing efficiency, and dust collection effectiveness. It<br/>processed 15 fresh leaflets per minute with 68.89% peeling efficiency and 18.67 dried<br/>leaflets per minute with a lower 51.79% efficiency. Dust collection was effective at<br/>83.97%, though minor leakage was noted. The machine showed stable performance at<br/>batch level, de-leafing around 23 of 30 leaflets per cycle, though it fell short of the target<br/>rates of 20 fresh and 25 dried midribs per minute due to feeder and roller limitations.<br/>Compared to reference machines, the prototype showed similar or better feeding efficiency<br/>but lower de-leafing success, particularly against De Vicente et al.’s model. However, it<br/>remains a safer and faster alternative to manual processing. Economic analysis showed<br/>strong viability, with profit margins exceeding 38% and a payback period under 212 days.<br/>Recommended improvements include adjusting brush clearance, sealing dust chamber<br/>gaps, integrating a scraper to prevent jams, and widening feeder slots to enhance<br/>throughput and reliability. |
