Development of solar-powered bottled waste reverse vending machine
(Don Mariano Marcos Memorial State University – Mid La Union Campus, 2025-05) Bagtas, Rhyeane Jhaye Z.; Abubo, Marvin S.; Casela, Kristine A.; Manuel, Leslie T.; Suniega, Rolando Jr C.
Development of Solar Powered Bottle Waste Reverse Vending Machine is a machine that enables users to receive a redeemable ticket equivalent to incentive rewards such as rice grains or coin change by inserting a piece of plastic bottle. The development of this machine seeks to promote a clean and green environment while providing users with an alternative way of recycling through motivation-based participation. This study employed a developmental, descriptive and evaluative research design. The study went through a total of five (5) trials to determine the ability of the machine’s operational capacity, detection of plastic bottles, time precision and dispensing of ticket. The study shows that (SPBWRVM) can detect any plastic bottle and hold up to approximately 355 plastic bottles. The system was programmed to detect plastic bottles and to dispense ticket within an accurate time duration.
Development of solar power system for COE student lounge

The Development of a Solar Power System for the COE Student Lounge (DSPSCOESL) integrates solar energy systems. This research project aims to develop effective design and construction for a fully functional system. Evaluation of the theoretical performances will be considered further to enhance the reliability and capability of the system. The demand for sustainable and eco-friendly solutions to energy needs has increased in recent years and is expected to grow faster in the coming years. The system integrates hybrid solar into a power system. The proposed system will be equipped with safety features ensuring that all the components are secured. This study aims to design, construct, and evaluate the theoretical performance of the system. The findings highlight that the system was able to provide the demand of the load connected into it. The battery duration is reliable in terms of its operation.
Development of rice hull pulverizer and pelletizer
(Don Mariano Marcos Memorial State University – Mid La Union Campus, 2025-03) Cabading, Bon Jozel A.; Casuga, Melvin Lloyd A.; Gumia, Ma. Elena M.; Maala, John Ivan B.; Miranda, Carl Angelo D.
Rice is one of the world's most important and essential crops, and its production generates a significant amount of agricultural waste, including rice hulls. In order to address and seek an effective solution, Development of Rice Hull Pulverizer and Pelletizer (DRHPP) was created which has the ability to transform rice hulls into useful organic fertilizer and pellets. This paper studied the design and assembly of the development of rice hull pulverizer and pelletizer following the Project Developmental research design. The DRHPP underwent 5 trials for each material used in the study which are rice hull, corn, molasses oil and water to attain reliable data to be evaluated. The pulverizing efficiency of the machine is 92.08% while its pelleting efficiency is 93.48%. The machine has a size quality of pellet of 61.96%. The Return on Investment of the DRHPP, on the other hand, is 15.14% that is said to be economically viable.
Development of motor-based whiteboard eraser
(Don Mariano Marcos Memorial State University – Mid La Union Campus, 2025-04) Landicho, John Carlo B.; Cudiamat, Rc Keynes J.; Escatron, Jose Rodrigo G.; Jappar, Sittie Norjanida M.; Ordinario, Angel B.
In the world of education, whiteboards are the most commonly used instrument. It can be used for conversation, teamwork, lectures, and other activities to communicate efficiently and understand what is being said. The researchers designed a motor-based whiteboard eraser that can erase writing in just one swipe because there are only a few whiteboards available in classrooms, and it takes time to erase all that has been written on them. This design will eliminate human labor, and reduce the time and health issues concerning the whiteboard marker. The system consists of a stepper motor, a rail system equipped with a gantry plate and linkages, an Arduino, and a cleaning bar to give that automation figure. When the button or remote control is switched on, it moves horizontally to fully clean the board. This Motor-Based Whiteboard Eraser is a great replacement for a manual eraser. It is a great help in making human work easier and eliminating human effort in cleaning the board.
Development of crop waste shredder
(Don Mariano Marcos Memorial State University- Mid La Union Campus, 2024-12) Jucutan, Joey Jr L.; Leiza, Ken Franz M.; Reloza, Kenneth Dominique D.
Agrochemical overuse, such as the overuse of pesticides and fertilizers, degrades soil health and lowers crop yields and quality. Shredded crop waste provides a viable substitute. In order to facilitate transportation and additional processing, crop waste must be finely processed. This research exhibits the creation of a crop waste shredder to facilitate the waste management and creation of a fertilizer substitute. Project development and descriptive-evaluative research design was used in the study. Experiments on a 10 kg waste revealed that shredding at intervals of 4, 8, 12, and 16 minutes produced more waste shreds.
