Development of coconut dehusking and shredding machine
(Don Mariano Marcos Memorial State University- Mid La Union Campus, 2024-11) Asuncion, Steven Dave R.; Antonio, Gerald Efraim S.; Bermudez, Jhue Bertson M.; Graycochea, Maico Henry G.; Marquez, Michael D.
This research focused on developing a Coconut Dehusking and Shredding Machine (CDSM) to increase the efficiency of traditional coconut processing procedures. The machine was developed with safety, dependability, and user-friendliness in mind, with features such a sturdy frame, a 7.5 HP gasoline engine, and a speed reducer to control the machine's operating speed. The major components, which included dual blade rollers and a support roller, were positioned carefully to maximize dehusking while reducing coconut damage. A shredding device was also included to facilitate husk processing. The development method included iterative design changes based on performance feedback. Challenges such as high roller speed and insufficient blade sharpness were solved by altering the speed reducer, improving blade edges, and regulating rollerspacing. Chains and sprockets replaced belts for increased longevity, while blade spikes were modified to keep the shredding mechanism from jamming. These changes assured that the equipment could process coconuts consistently without experiencing mechanical issues. The final machine is a safer and faster alternative to manual dehusking, with perfect component alignment and intentional design decisions that improve stability and effectiveness. The CDSM's design emphasized the significance of repeated testing and changes, resulting in a system that considerably enhances traditional coconut processing while focusing on operator safety and convenience of use.

Agricultural waste poses a significant environmental challenge, particularly in residential areas, where it accounts for the largest source of waste generation. To address this issue, the Development of an Agri-Waste shredder (DAWS) for organic fertilizer production is proposed. This paper adopts a project-developmental research design to explore the design and construction of the AWS and evaluate its effectiveness in processing common agricultural waste materials. Through ten trials for each material, the AWS’s performance was assessed in terms of shredding efficiency, particle size distribution, and throughput. Data collection was encompassing research on existing DAWS designs, design prototyping, and systematic trial evaluations. Statistical analysis was used to compare the AWS’s performance across different materials, informing further refinement of the design and operating parameters. The study aims to contribute to sustainable waste management practices by converting agricultural waste into valuable organic fertilizer. The findings were advanced the utilization of agricultural waste as a resource for organic farming, promote environmental sustainability, and reduce dependence on chemical fertilizers. The creation of an effective AWS ultimately can improve soil fertility, support sustainable agricultural practices, and reduce pollution from agricultural waste.

(Don Mariano Marcos Memorial State University – Mid La Union Campus, 2025-04) Hipol, Nathanael Frances V., Galvan, Gwenneth Marie G., Marrero, Menglei C., Quirimit, Mark Aldrin J., Rivera, Trisha M.
Water is a vital resource, yet access remains a challenge for many rural communities, particularly in the mountainous regions of the Philippines. The Hydraulic Ram Pump (HRP) offers a sustainable solution by utilizing the hammering effect to transfer water to higher elevations without relying on fuel or electricity. This study focused on designing and fabricating HRPs while evaluating their performance, specifically maximum discharge height and pump efficiency, based on input and output flow rates. Two configurations, -inch and 14-inch ram pumps, underwent 15 experimental trials to assess the impact of design variables. Results showed that higher source elevations increase system pressure, while larger pipe diameters boost water flow and waste valve cycling. For every 0.4-meter elevation gain, a l-psi pressure increase was observed. enhancing lift height. This study highlighting the HRP as a cost effective solution, is conducted in Pagdalagan, City of San Fernando, La Union, from September 2024 to April 2025.
Bubble wrap for pipe production machine
(Don Mariano Marcos Memorial State University – Mid La Union Campus, 2024-12) Songaben, Melvin H., Aquino, John Paul C., Ganaden, Jhundale G., Tadije , Mark T., Tejada, Ezekiel Griel S.
Bubble wrap, a widely used packaging material introduced in the late 1950s, has revolutionized the protection of fragile products during transit and storage. However, its durability and reliance on single-use plastics contribute significantly to environmental issues. The improper disposal and increasing volume of bubble wrap waste exacerbate the global plastic waste problem, particularly from e-commerce. In response to this challenge, the researchers developed a machine designed to shred bubble wrap and repurpose it into plastic pipes. This initiative aims to address plastic waste management, promote sustainability, and offer a more environmentally friendly alternative for pipe production in various applications. The machine's performance was evaluated by measuring production time, throughput capacity, and overall efficiency. Data collection involved five trials are done in the shredding process and the same with the molding process. Results showed an average throughput capacity of 0.854 feet per hour, a shredding efficiency of 69.1%, and an overall machine efficiency of 66.7%. The shredding component demonstrated the highest efficiency, highlighting its critical role in the machine’s performance. This study presents a sustainable solution to plastic waste, contributing to environmental preservation and resource innovation.
