Publication 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.Publication 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.Publication 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.Publication Development of microcontroller-based backwash controller for water refilling stations(Don Mariano Marcos Memorial State University- Mid La Union Campus, 2025-05) Sinocruz, Rona Mae N.; Ducusin, Christine Angel F.; Ducusin, Rodelyn H.; Hidalgo, Jynah Rose E.; Laconsay, Rhainzel G.The backwashing process plays a critical role in maintaining the efficiency of water filtration systems in water refilling stations. This study focuses on the development of a Micro-Controller based backwash controller tailored for use in such stations, based on the principles outlined in existing filtration and backwashing methodologies.

Users can remotely control the system, track progress, and make updates using a mobile app or web interface based on IoT. Using four important parameters: throughput capacity, temperature-drying time, time duration for per temperature setting, energy consumption per temperature-time combination the technical performance of the system was assessed accordingly. The IoT-based chili dehydrator was proven to enhance efficiency significantly while drying, minimize processing time, and enhance end-product quality, as indicated by preliminary results. The analysis of energy consumption also indicates that the system is environmentally friendly and economical. This research confirms that the IoT-based chili dehydrator is easy to use and scalable for chili processing, thus ensuring end-product quality and sustainability while enhancing agricultural practice.Publication 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.Publication Cultivator with monitoring and control system for oyster mushrooms(Don Mariano Marcos Memorial State University – Mid La Union Campus, 2023-12) Guerrero , Harris D., Dominno, Neliadelilah M., Garcia, Jayson Arel A., Lago, Mikaela L., Olpindo, Jerome Christopher M.The Mushroom Cultivator provides a concise overview of the cultivation process for mushrooms, elucidating key aspects and methodologies.
