Abstract

The damage of cutting effect the product a lot, thus reducing the quality and dimensional change of the product. This research aims to monitor damage of cutting tool throught the accelerometer and strain gauge sensors on the process of turning Rod hydraulic cylinder SAE 1045 using cutting carbide coated. The machining process is carried out by the variation of cutting parameters, depth of cut 0,5 and 1,0, feed rate o,5 and 0,7 mm/min, and constant cutting speed of 1300 rpm. This experiment is conducted on three cutting tool condition they are new, medium wearing (0,15 mm) and critical wearing (0,3 mm). The censors used are accelerometer and strain gauge which are placed in the holder. The result show that kurtosis, RMS and standard deviation parameters are influenced by the tooling condition. Have the relation toward the wearing change of tooling, this case is showed by the existence of progress from the new, medium and critical tooling test. As for amplitude strain gauge signal also showed a significant change when there is damage to the wearing tools. This showed that the bigger wearing happening the higher signal out going.

Abstract

The high number of inmates in narcotics cases in Indonesia demands comprehensive coaching to support social reintegration. This study aims to describe the implementation of the job guidance program at the Class IIB Narcotics Prison in Purwokerto and its impact on the skill development of the inmates. Using an observational descriptive method, data was obtained through field observation, in-depth interviews, and literature studies for ± 40 days. The results of the study show that job guidance activities such as catfish cultivation, handicrafts, agriculture, ecoprint, and gastronomy make a significant contribution to improving practical skills, confidence, and work readiness of the inmates. These programs not only equip the inmates with technical skills, but also foster an entrepreneurial spirit and minimize the risk of recidivism. With a structured training approach, job guidance activities at the Class IIB Narcotics Prison in Purwokerto have proven to be an effective strategy in the process of rehabilitation and empowerment of inmates.
