An HHO generator is a device that electrolyzes water to produce a mixture of hydrogen and oxygen gases, which can be used as a fuel source for various applications such as welding, cutting, and combustion engines. The efficiency and production rate of HHO generators are influenced by various parameters, including electrode materials, voltage, current, and electrolyte solutions. This study aimed to evaluate the oxyhydrogen production of an HHO generator by conducting parametric analysis. A complete setup consisting of a modular HHO generator, a bubbler, and a device for measuring the volume flow rate was constructed and used in a series of experiments to determine the effects of electrode material, electrolyte solution, applied current, and plate geometry on oxyhydrogen production. The results were evaluated and analyzed using the Pareto principle, which indicated that plate geometry and input current were the most significant factors, while the other two were considered less critical. The surface area of the plates was the most significant factor affecting oxyhydrogen production, while the type of material used as an electrode was the least significant. The highest oxyhydrogen production rate, averaging 0.504 L/min over three trials, was achieved using grooved stainless-steel 316L plates in a Potassium Hydroxide (KOH) solution with a 280-ampere current. Corrosion tests indicated that stainless steel 316L in KOH solution had the lowest corrosion rate (5.043 × 10-4 MPY), while stainless steel 304 had the highest (1.009 × 10-3 MPY).

The study may set the threshold to determine if the results of the areas mentioned above are beyond the passing rate and implement the interventions for each area. A content management system was also used in this paper to change the contents of the Alumni Program Evaluation, the interventions, the threshold, and many more. The developed web-based system includes an evaluation of the Alumni Program across key areas such as Curriculum, Faculty, Facility, Laboratory, and Student Services. This study employed a purposive sampling technique to identify the group of respondents. There are a total of 152 respondents who participated in this study from the Information Technology department and IALAP office. The study results indicate that no interventions are necessary in any of these areas, as both the mean and the composite mean surpasses the 3.50 threshold set in the system. Among the five areas, the faculty received the lowest passing mean, followed by student services and the laboratory. This underscores the potential for continuous improvement in these specific areas influencing the employability rate and skills of the alumni-participants. The time series analysis was conducted on a two-year dataset, covering 6 trimesters. The analysis revealed a positive improvement in evaluation scores as the trimesters progressed across five dimensions of alumni program evaluation. This suggests that alumni respondents consistently agreed in their evaluations of appreciation on the improvements made by the school administration which enhances their life experiences and technical skills during their stay in the campus.
