Fern diversity in Don Mariano Marcos Memorial State University forest reserve, Bacnotan, La Union, Philippines
(Don Mariano Marcos Memorial State University- North La Union Campus, 2024-05) Abunan, Jericho T.
This research assessed the diversity, conservation status, and endemism of ferns in the Forest Reserve of Don Mariano Marcos Memorial State University- North La Union Campus, Sapilang, Bacnotan, La Union. Two repeated transect walks were done with a
total of 26 plots (10 plots from area one and 16 plots from area two). Specimens were
collected, identified, and assessed for their conservation status and endemism. The inventory revealed 14 species under five families of ferns in the study area. The study shows that eight were identified as endemic in the Philippines and four were identified as widely distributed not only in the Philippines but also in other countries. The species that has the highest relative density and important value was the Arthropteris palisotii (Desv.) Alston, while the species that ranked first in terms of relative frequency was Adiantum philippense L. The species that has the highest fresh and dry weight of all the species is Nephrolepsis acutifolia (Desv) Crists. Moreover, the result of the study showed a high diversity index (0.90) and low level of diversity (2.36). Generally, the study shows the unbalanced distribution of fern species in the DMMMSU Forest Reserve.
Two-way mobile agricultural spraying machine
(Don Mariano Marcos Memorial State University – Mid La Union Campus, 2026) Ganaden, Jet P.; Fernandez, Dexter B.; Meana, Errol C.; Sibayan, Chanda Mae M.
This study developed a Two-Way Mobile Agricultural Spraying Machine (TWMASM) to address the ergonomic and health risks associated with manual knapsack sprayers used by Filipino farmers. Utilizing a Design and Development Research (DDR) approach, the machine was fabricated with a steel frame, a 16-liter tank, and a six-nozzle boom, powered by both a manual chain-drive and a solar-electric system. Performance trials on a corn plot revealed that the solar-powered mode significantly outperformed the manual mode, achieving a mean field efficiency of 54.92% compared to 36.51% (p < 0.05). Economically, the prototype was constructed for ₱7,100.00 with a Benefit-Cost Ratio of 4.00, indicating high viability. By providing a cost-effective, ergonomic, and efficient alternative, the TWMASM supports the Philippine Farm Mechanization Roadmap while enhancing farmer productivity and safety.
Microcontroller-based vendo charging station
(Don Mariano Marcos Memorial State University - Mid La Union Campus, 2025-05) Ravela, Dexter T.; Acosta, Hannah Grace M.; Andrada, Jake M.; Cabiles, Alijanna Jeame C.; Notarte, Jaspher Kim A.
This study presents the design, development, and evaluation of a coin-operated, microcontroller-based charging station intended to provide a convenient and accessible solution for recharging electronic devices, particularly in areas with frequent power outages or limited access to conventional electricity. The primary objective was to construct a fully functional prototype—termed the Microcontroller-Based Vendo Charging Station—and assess its performance in terms of operational efficiency and charging effectiveness.The system integrates an Arduino Nano microcontroller, relay module, LCD display, and coin slot mechanism, all governed by custom-developed software. The charging process is activated upon coin insertion, with the system managing current flow and monitoring the charging duration accordingly. Experimental testing demonstrated consistent performance, including a rapid coin detection response averaging 0.65 to 0.67 seconds. Within a fixed 15-minute charging cycle, the system delivered notable power increases—approximately 20% for smartphones and 38% for laptops—highlighting its reliability and compatibility with various devices. Results affirm the technical viability of constructing the device using affordable, readily available components and open-source tools. The system consistently met performance expectations, including reliable coin recognition and effective energy delivery, aligning with the intended project timeline. Its promising output further supports its application as a practical, short-duration charging solution for public and emergency-use contexts. In conclusion, the project achieved its core goals and demonstrates potential for broader deployment. Future enhancements may include exploring cost-reduction strategies, adding protective measures for connected devices, conducting long-term durability tests, and collaborating with electronics professionals to refine the system’s safety and robustness.
Microcontroller-based security system with multiple sensors for robbery/theft
(Don Mariano Marcos Memorial State University - Mid La Union Campus, 2025-05) Agadang, Denver S.; Lopez, Jamaica L.; Nisperos, Angela A.; Quindara, Christian Dave L.; Tino, Chester T.
The Microcontroller Based Security System with Multiple Sensors for Robbery/Theft is a security system used to reduce the success rate of robbery/theft for the said establishment, serving as a cost-effective, long-term investment for a profitable business which provides more efficient and faster crime response, leading to unsuccessful robbery/theft related crime and a safer environment. The concept and design of the Microcontroller Based Security System with Multiple Sensors for Robbery/Theft was feasible using a microcontroller. This research used project development type of research design and the Engineering Design Process (EDP) to conceptualized the design and specifications of the security system. The researchers also made revisions after testing and observation until the security system was deemed functional and acceptable. Overall results show that the microcontroller-based security system with multiple sensors for robbery/theft was deemed functional in monitoring the amount of time it activates through the laser sensor, voice recognition, and the switch.
Microcontroller-based seashell crusher-pulverizer machine
(Don Mariano Marcos Memorial State University - Mid La Union Campus, 2025-05) Tamayo, Jhemelyn Mae A.; Balanon, Jazztin Kaveh B.; Donato, Ma. Crystal Jade A.; Garcia, Christopher J.; Lavaro, Sherrine Paula D.
Seashell waste is a widely available byproduct with significant potential for agricultural applications. This study presents the Microcontroller-Based Seashell Crasher-Pulverizer Machine, a microcontroller operated machine designed to crush and pulverize discarded seashells into fine particles. The machine utilizes a motorized crushing mechanism controlled by a microcontroller for precise and efficient operation. Performance tests evaluated the machine's effectiveness in terms throughput capacity, production efficiency, and facilitate versatility. The pulverized seashells were analyzed for potential applications in agriculture, and animal feeds, showcasing their value as sustainable raw materials. Results demonstrate that the seashell crasher pulverizer provides a cost-effective and environmentally friendly solution for managing seashell waste while contributing to resource optimization. This research highlights the potential for simple yet impactful technologies to promote sustainability and waste utilization in various industries.
