Abstract:The study focused on designing, creating, constructing, and evaluating an OpAmp Solar Charge Controller. The research included the development phase covering the design's technological viability, while the descriptive evaluation phase covered the technical results, economic feasibility, and environmental soundness assessment. It was found that the unit was usable and a reliable means of charging a battery, based on design and performance testing. All were highly viable and legitimate in technical efficiency, economic and financial viability, environmental soundness, political acceptability, and social acceptability. The built device is, therefore, feasible by providing a 49.155 for business undertakings.

Abstract:The design, development, fabrication, and evaluation of Clean-in-Place Machine for Liquid-Cooled Engine (CIP machine), a type of clean-in-place technologies that was never in any form applied in automotive technology especially for engine cooling system. This is the researchers’ response to address the problem of small automotive shops regarding the unavailability of tools or machines used for holistic cleaning of engine cooling system. This machine can be made affordable for all automotive shop owners and also for technical education institutions. The development phase covered the technical feasibility of the prototype CIP machine. The descriptive-evaluative phase covered its evaluation by experts and end-users using the DOST Technology Assessment Protocol (TAP-TEEPS). This evaluation protocol includes assessment of technical and economic feasibility, environment soundness, political and social acceptability (TEEPS). Based on the trial conducted, it was found out that the CIP machine was able to clean the entire engine cooling system faster and better compared to the traditional manner of cleaning the engine cooling system, which is reflected in the high evaluation rating of the experts, hence, the CIP machine is recommended for use by automotive practitioners and based on the computed ROI of 1, 052 percent. The payback period is one month and two days; this means investing in the CIP machine is worth undertaking.

Abstract:Objective: The objective of this study is to develop and evaluate the acceptability of an addressable fire alarm system trainer designed to enhance the skills and preparedness of emergency responders and training institutions, thereby contributing to Sustainable Development Goal 4 (SDG 4) – Quality Education. Theoretical Framework: This research is grounded in experiential learning theories which emphasize the value of hands-on experiences for comprehension and skill acquisition. Studies by Esu et al. (2016) and Taupa (2017) underscore the significance of resource availability in technology education, particularly in emergency response training. Method: A descriptive research design was employed to assess the trainer’s acceptability. The study involved the design and construction of the addressable fire alarm system trainer and utilized expert evaluations for data collection on usefulness, effectiveness, functionality, safety, and social acceptability. Results and Discussion: The findings revealed that the trainer received high acceptability ratings across all indicators, with overall means of 4.73 for usefulness and 4.84 for functionality. Experts acknowledged its potential in educational settings, underscoring the importance of integrating advanced fire safety technologies into training curricula to promote quality education (SDG 4). Research Implications: The implications of this research emphasize the necessity of innovative training solutions in fire safety education, suggesting that the developed trainer can significantly improve instructional practices in technical education fields. Originality/Value: This study contributes to the field by delivering an innovative educational tool that addresses the gaps in training resources for fire safety systems. Its unique design and framework provide a model for similar initiatives in vocational education, highlighting the value of practical training in preparing skilled emergency responders.
