The traditional manual method of removing dried coconut kernels from shells is labor-intensive, time-consuming, and poses a risk of injury to workers. To address these challenges, this study developed an Oscillator-Based Coconut Dried Kernel Scraper to enhance efficiency, safety, and productivity in the coconut processing industry. The device utilizes an oscillatory mechanism driven by an electric motor to produce a controlled scraping motion, facilitating the effective detachment of the dried kernel from the shell with minimal physical effort. Key components of the prototype include a motor-driven oscillating blade, a kernel-holding fixture, and a safety enclosure. The design emphasizes the use of locally available materials and user-friendly operation. Preliminary testing demonstrated a significant reduction in processing time and operator fatigue compared to manual scraping methods. Furthermore, the researchers conducted a comparative performance evaluation between manual and mechanized scraping, with participants indicating a strong preference for the oscillator-based scraper. The product achieved the highest scores for efficiency and user satisfaction, particularly among small- to medium-scale coconut farmers. Based on these findings, it is recommended that future improvements include enhancements in design and the integration of a capacitive sensor to automate and further refine the control system.

Postharvest seed cleaning is critical for ensuring high-quality rice seeds suitable for storage and planting. Traditional cleaning systems, which are often limited to one or two sieves, are insufficient for removing all impurities, resulting in reduced seed purity and potential germination issues. This study was designed to enhance the rice seed cleaning system by integrating a high-efficiency blower with a triple-sieving mechanism. The system utilized three sieves with progressively smaller mesh sizes to systematically separate contaminants such as dust, broken grains, husks, and other foreign particles. A controlled airflow from the blower distributes rice seeds uniformly across the sieves, optimizing separation while minimizing mechanical damage. Compared to existing conventional systems, the proposed design demonstrated significantly improved cleaning performance, resulting in higher seed purity levels and overall enhanced seed quality. The triple-sieve configuration, coupled with precise airflow control, led to more effective impurity removal and uniform seed handling. The improved seed-cleaning system offers several agronomic benefits, including reduced postharvest losses, increased seed germination rates, and improved crop establishment. By producing cleaner, higher-quality seeds, this system has the potential to support more efficient and productive rice cultivation. Full article

Microfinance institutions (MFIs) are vital in promoting financial inclusion for underserved populations. However, these institutions face growing security threats, including sophisticated burglary tactics like underground tunneling. In the Philippines, notable incidents, such as the “Termite Gang” heist in Marikina City and a mall robbery in Ozamiz, highlight the limitations of conventional security systems in addressing subterranean intrusions. This study addresses the gap in existing security technologies by developing a real-time detection system that integrates a vibration sensor, a Global System for Mobile Communications (GSM) module for sending real-time SMS alerts, an audible alarm, and a solar-powered backup system for continuous operation. The system was simulated in the electrical technology laboratory to enhance classroom learning. The system’s core is an Arduino Uno microcontroller that processes inputs from the SW-420 vibration sensor, activating alarms and triggering SMS notifications via the SIM900A module when it detects unusual vibrations. Simulations A, B, and C were conducted to evaluate the system’s response time, with results showing a progressive reduction in detection time from five seconds to one second, indicating improved calibration and system efficiency. These findings also support the existing literature on user interaction with vibration alerts, demonstrating high accuracy in interpreting haptic notifications and the cognitive trade-offs involved. The proposed solution offers a proactive, energy-resilient, and cost-effective security system specifically designed to address underground burglary attempts. It applies to MFIs, pawnshops, and other high-risk financial environments. Future research should explore the application of machine learning for adaptive threat detection, expand the system’s scalability, and integrate mobile applications to enable user customization and enhance alert management.

Technical higher education in the Philippines is a government priority, as it equips learners with the technical knowledge and practical skills necessary to develop industry and technology-ready human capital. In parts of Mindanao, the Philippines, where socio-economic and technological challenges are significant, Industrial Technology Education (ITE) learners must be equipped with relevant, comprehensive knowledge of industry trends. A sequential explanatory mixed-methods design was employed in this research, combining quantitative surveys with qualitative interviews to provide a comprehensive analysis. Five hundred twenty-six learners participated in the survey, and six were selected for in-depth interviews. The findings highlight the significant impact of familial and peer support on fostering confidence, encouraging academic perseverance, and improving mental health. However, financial hardships and inadequate emotional support remain significant obstacles. The study emphasizes the importance of cultivating an inclusive campus atmosphere via awareness efforts, accessible services, and mentorship programs to guarantee fair educational opportunities. For this reason, the implementation of personalized education plans, flexible learning, digital access, academic and educational support, and an institutional support system is highly encouraged to address learners’ essential needs. The research findings also suggest integrating mentorship programs, adopting inclusive learning practices, developing an adaptable curriculum, and providing mental health support services for learners, particularly those with disabilities. By aligning the curriculum with industry specifications and standards and providing well-planned support frameworks, higher education institutions in Mindanao can produce graduates who are professionally qualified, highly skilled, well-mannered, and career-prepared, fully equipped to meet the demands of the dynamic workforce.

Sustainability in higher education plays a crucial role in shaping future professionals with an eco-conscious mindset. This study focuses on developing and simulating a portable solar food dehydrator as a practical application of sustainability principles in technology education. By integrating sustainability into the curriculum, this research enhances students’ technical skills while promoting the use of renewable energy and effective food preservation methods. Furthermore, the project aligns with green campus initiatives by encouraging energy-efficient practices and reducing food waste. This study emphasizes the significance of education for sustainable development by offering learners hands-on experience in designing eco-friendly solutions, promoting innovation, and equipping them to contribute to a more sustainable future. A food dehydrator is a device that removes moisture from food to aid in its preservation, utilizing a heat source and airflow to reduce its water content. The researchers used two methods to dehydrate food: direct sunlight (sun drying) and indirect sunlight (solar drying). The study used a developmental research design. Simulations revealed that, with solar-powered electricity, the longer the drying time, the greater the reduction in the moisture content. This was evident in the eighth experiment, which was conducted on fruits and vegetables. While drying with direct sunlight, the same trends, albeit to a lesser extent, were observed in the reduction in the moisture content of the fruits and vegetables. These insights can inform future design improvements, making the products more visually appealing and distinctive, thereby enhancing their attractiveness and novelty. Full article

The study investigated the tensile strength and elongation properties of abaca fiber-reinforced polymer (AFRP) composites after varying durations of seawater soaking, with a focus on their potential for reinforcing fiber-optic cables. It aims to bridge industrial technology education, experiential learning, and green technology by evaluating abaca fiber as a sustainable alternative to synthetic aramid yarn. Conducted at Caraga State University, Cabadbaran Campus (CSUCC), the research utilized a quasi-experimental product development design involving industrial technology students and instructors. Tensile strength testing and comparative analysis were performed on abaca fiber samples (A, B, and C) subjected to different seawater soaking durations. Results show that soaking time significantly affects the fiber strength, with Sample A achieving the highest tensile strength (5631.5 MPa) and Sample C the lowest (1679.8 MPa). Findings indicate that prolonged exposure to seawater weakens abaca fiber, emphasizing the need for controlled treatment to optimize its industrial applications. This study emphasizes the importance of hands-on learning in industrial technology education, promoting critical thinking and technical skills while underscoring sustainability. The research advocates for eco-friendly materials in industrial applications and highlights the potential of abaca fiber composites. Future studies should investigate pre-treatment methods to enhance fiber durability, assess the long-term environmental performance, and conduct large-scale pilot testing to evaluate commercial viability. By integrating sustainable innovations into industrial technology education, this study contributes to advancing natural fiber composites for manufacturing and telecommunications infrastructure.
