Abstract

This community service program aims to improve the technical skills and job readiness of inmates at Class IIA Labuhan Ruku Prison through basic welding training. The training method applied a combination of hands-on practice, lectures, and intensive mentoring, involving 20 participants, most of whom had no prior welding experience. The results indicated a significant improvement in participants’ technical skills, motivation, and self-confidence, with 90% of them successfully performing basic welding independently. Participants’ satisfaction with the program was also high, with an average score of 4.5 out of 5. The limitation of this program lies in its short duration and the absence of official certification as a formal recognition of participants’ skills. The absence of formal certification limits participants’ access to directly enter the industrial labor market, thus the outcomes of the training are more optimally directed toward strengthening economic independence through small welding workshops or ent

Abstract

The objective of this study is to investigate the performance of a horizontal shaft wind turbine model with variations in blade shapes. The focus of the research lies in examining the impact of different blade shapes, specifically the curved shape, inverted linear taper, and rectangular shape measuring 8 cm x 20 cm at a 200 tilt angle. The experiments are conducted at various wind speeds: 7, 8, 9, 10, and 11 m/s. The findings reveal that changes in blade shape significantly influence the operation of the horizontal shaft wind turbine. The Brake Horse Power (BHP) reaches its maximum with a rectangular blade shape, achieving 1.1 watts at a wind speed of 11 m/s and a corresponding torque of 0.0221 Nm. Additionally, the highest efficiency is attained with the rectangular blade shape at a wind speed of 7 m/s, reaching 21%.
