Abstract
The graduate thesis/project study entitled “Design and Development of Energy-saving Solar-powered Portable Public Address System was developed to provide a sound system for orientation and public speaking. Some portable public address models have limitations, that is, they can only be operated and charged in on-grid power source. In this technology, it has solar panel that charges through sunlight, battery for storage of current, amplifier, speaker and power monitoring system. With this feature, it can be operated and used in areas with power failure and power shortage problems especially in rural and remote areas.
The project was conducted at Lupon School of Fisheries. It was tried, tested and evaluated by student, instructors as well as experts in the industry. The data was gathered and analyzed using weighted mean and one sample t-test. Based on the evaluation as perceived by the evaluators, the functionality in terms of performance, maintenance and design and cost effectiveness resulted as highly functional. It was concluded that the project can be designed and developed. The result was highly functional with an average rating of 4.81 in terms of performance, highly acceptable with an average rating of 4.75 in maintenance and design and highly affordable with an average rating of 4.69 in cost effectiveness. There were revisions made to solve defects found during testing. It was recommended that further study be conducted to improve its design and functionality.
