Thesis (Bachelor of Technology major in Electrical Technology) -- University of Rizal System-Morong.
EXECUTIVE SUMMARY: This study entitled Developed Coin Slot Machine Solar Charger was conducted in University of Rizal System, Morong during school year 2016-2017. The device was constructed out of locally available materials. There were thirty (30) respondents of the study, ten (10) electronics and electrical technology experts and twenty (20) end-users of mobile phone. They were selected through purposive random sampling, since they have knowledge in operation of mobile phone charger. They evaluated the developed device in terms of usefulness, safety and maintenance, durability and functionality. The data gathered in the study were statistically treated using qualitative description, weighted mean and T-test. The study found out that the coin slot machine solar charger can be constructed out of locally available materials. The Developed coin slot Machine solar Charger was tested for operation where troubles are observed and revised. Through try-out and revisions made, the project reached the functional output and attained the objectives. The Developed device was evaluated and extremely accepted by the two groups of respondents in terms of usefulness, safety and maintenance, durability and functionality. The researchers utilized the researcher's-made questionnaire checklist in evaluating the acceptability of the developed device. The null hypothesis states that there is no significant difference on the evaluation made by the experts and end users on the acceptability of the acceptability of the Developed Coin Slot Machine Solar Charger in terms of usefulness, safety and maintenance, durability and functionality is accepted, therefore not significant. It was concluded that the Developed Coin Slot Machine solar Charger was designed and constructed out of locally available materials; the developed Coin Slot Machine Solar Charger was extremely accepted as Evaluated by the experts and end users in terms of usefulness, safety and maintenance, durability and functionality. The null that here is no significant difference on the evaluation made by the two groups of respondents is accepted. Based on the findings and conclusions, the recommendations were hereby offered: Utilization of the developed device and provision for mass production are suggested. Follow up study on the effectiveness of the Developed Coin Slot Machined Solar Charger should be undertaken; Feasibility study for possible mass production should be taken into consideration; Other research instrument should be revised in order to test other variables that may affect the performance of the project.
