Design and development of a hydraulic ram pump (HYDRAM)
(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.
Automated saltwater crystallization system
(2025-04) Ducusin, Arvi Anne L., Alcantara, Victoriano Nikolai T. III, Pineda, Jet Denver S., Sulvita, Jannah Marie D.
This research focuses on developing an Automated Saltwater Crystallization System (ASCS) to address these issues. The ASCS was designed to optimize the crystallization process through controlled heating and mechanical processes. The study aims to design, fabricate, and evaluate the ASCS's technical performance, particularly in terms of production rate, time, and machine efficiency. A comprehensive cost and return analysis is included to assess its economic viability, addressing metrics such as break even points, payback periods, and benefit cost ratio. Results indicate that the ASCS can enhance local salt production, mitigate environmental impacts, and improve resilience against climate challenges like La Niña which revealed a break-even point of 187.172 kg/year, a payback period of 170 days, and a benefit-cost ratio of 1.03. This innovation demonstrates the potential to revitalize the Philippine salt industry, ensuring sustainable production and reducing dependency on imports.
Smart Portable Rice Miller
(Don Mariano Marcos Memorial State University- Mid La Union Campus, 2023-05) De Guzman, Ronald A.; Gali, Justin Romsr E.; Niñalga, Aaron Frank S.; Tamonda, Charlie Dave R.
The Smart Portable Rice Miller is a modern, compact, and efficient solution designed. Engineered for energy efficiency and ease of transport, the system includes smart technology and milling mechanisms, ensuring consistent milling capacity and milling efficiency. It features a user-friendly control panel and current sensor that monitor current and overload current protection to prevent malfunctions and ensure safe operation. Its portability and reliability make it ideal for decentralized rice milling operations to lessen extensive transportation. Specifically, the study aimed to design, construct, create a
program and evaluate the performance of SPRM. Descriptive developmental research design in conjunction with the engineering design process was used in this study. The machine was evaluated to its technical performance by the said statistical method. Further findings indicated that SPRM was made in accordance with its description and specifications. Thus, the SPRM can be adopted by the farmers or small community concerned in rice milling.
Smart Monitoring For Electrical Loads Of DMMMSU-MLUC COE
(Don Mariano Marcos Memorial State University – Mid La Union Campus, 2024-12) Apillanes, Menchie P.; Cabello, Adeline S.; Cajuday, Melanie G.; Damian, Belle Kimberly c.; Hufalar, Clarie P.
This research investigates the implementation of a smart monitoring system for electrical loads within a school environment. The system aims to optimize energy consumption, identify potential faults, and enhance the overall efficiency of electrical infrastructure. Data acquisition is achieved through strategically placed sensors measuring voltage, current, and power, transmitting data wirelessly to a central processing unit. Advanced algorithms analyze this data to detect anomalies, predict potential failures, and provide real-time insights into energy usage patterns. The system's effectiveness is evaluated through a comparative analysis of energy consumption before and after implementation, highlighting cost savings and operational improvements. This research contributes to the development of sustainable and efficient energy management strategies in educational institutions.
