This project study aimed to design, fabricate, and test a remote-controlled, self- propelled lifebuoy that can save a single and conscious drowning victim. This project was made to rescue the drowning victim without endangering the life of the rescuer. This device is much faster as compared to lifeguard’s average time of swim to reach and save the victim, which can lessen the health risk or complication of the victim. This lifebuoy carries an inflatable floatation device that inflates through a mechanism controlled by the operator of the buoy just before it reaches the drowning victim where he/she can easily grasp. This inflatable floatation device will serve as the drowning victim’s aid to stay afloat while slowly being pulled by the lifebuoy towards a safe place for appropriate medical attention and care. This project is composed of inflatable floatation device, brushless motor, water jet pump thruster, li-po battery, radio transmitter, servo motor, and electronic speed controller. This device could travel and operate at fair to moderate weather and is capable of saving a drowning victim with a distance up to 300 meters. It could turn itself right side-up after it is thrown in the water or strike by waves.

This study intends to contribute to the creation of reliable and efficient wind turbine systems in light of the rising environmental concerns and the requirement for sustainable energy sources. This study focuses on the design, construction, and performance evaluation of a four-bladed horizontal axis wind turbine (HAWT) for electricity generation. This study aimed to contribute to the development of efficient and reliable wind turbine systems. The choice of analyzing a four-bladed HAWT and not the conventional 3 blade is because with 4 blades, the wind turbine can produce more torque at lower wind speeds, allowing it to be more applicable for low wind speed areas. Commonly vertical axis wind turbines are the choice for low wind speed areas, although their efficiencies are not as good as those of HAWT's. The research investigated the efficiency of the HAWT through parameters such as power coefficient, cut-in speed, revolutions per minute (RPM), and tip speed ratio. The objectives included designing and constructing the HAWT and evaluating its performance under load and no-load conditions. The data collected were analyzed and interpreted, providing insights into the efficiency and potential improvements of the four-bladed HAWT for sustainable energy generation.

For farmers with difficulties when planting corn, they need portable tool that would eliminate bending down as well as reduced planting time. As they face difficulties, one example is straining their back due to bending down for hours. Thus, the aim of was study is to design, fabricate, and test a portable tool, proved that the Portable corn planter is remarkable for reducing corn planting time. It allowed the user to dispense corn competitively against traditional tool. One of the limitations of using the tool was its metering mechanism where it would only dispense specific variety of corn seed and with correct size. Portable corn planter would be a practical substitute to the traditional tool providing efficiency when planting corn. The device was fabricated successfully, assembled, and tested for data gathering. The device was able to plant corn 37.9% on average faster than the traditional corn planting tool proving that the specific objectives and targeted improvements for manual corn planting using the traditional tool as baseline were achieved with the improved tool.

Agricultural production such as corn has been one of the most abundant crops in the Philippines. Corn has become the most abundant crop of Brgy. Badiangan Ajuy. The specified barangay Badiangan is a beneficiary barangay of Central Philippine University - College of Engineering. The researchers aim to design, fabricate, and test a bagging machine to replace the manual bagging into an automatic grain bagging process of the existing biomass fired batch type flat-bed dryer in Barangay Badiangan, Ajuy, Iloilo. The researchers designed and fabricated a bagging machine using the suction created by a centrifugal blower for its conveying mechanism. The conveyed corn carried by the air suction produced by the blower is separated from the air in the cyclone separator using the principle of pressure difference which acts as density separation. The corn collected inside the cyclone separator is then bagged by the operators. The motor used for the machine produce a power output lesser than the calculated power due to financial constraints and the availability of electric motor that can produce the required power. The results of the testing showed that 1 sack of corn averages 5 minutes and 20 seconds to be bagged. Abstract only 2022-07-01T00:00:00Z
