This study focuses on the development of a sustainable energy generation system using a human-powered LAT pull-down mechanism. The system was designed to convert human motion into usable energy, integrating a solar charge controller and battery for continuous energy production. A series of materials such as metal bars, bike sprockets, and a magneto were utilized, replacing an initial alternator due to low RPM output. The system was tested and revised to address issues related to voltage stability, connectivity, and energy transfer. Through these revisions, stable power output was achieved, making the system a viable sustainable energy solution. The study aimed to assess the acceptability of the developed system in terms of functional stability, performance efficiency, usability, reliability, and maintainability. Respondents, consisting of 10 experts, evaluated the system using a survey instrument, which was validated by experts in the field. Findings showed that the system was strongly acceptable in all categories, with the highest ratings in maintainability with 4.73 mean and reliability with 3.85 mean. However, areas for improvement were identified in operational integrity and durability of components. Based on these findings, recommendations were made to enhance operational integrity, optimize energy conversion efficiency, improve durability through better materials, and establish clear maintenance protocols. The study supports the feasibility of human-powered energy generation systems and emphasizes the need for continual improvements based on user feedback and long-term performance evaluation.
