ABSTRAK Lubis, Didin Zakariya. 2013. Effect of Occupational Health and Safety for The Satisfaction and Healthness of Machines Production Workshop Workers at District Tulungagung. Minithesis. Mechanical Engineering Department, Faculty of Engineering, State University of Malang. Supervisors: (1) Drs. Solichin, S.T, M.Kes., (2) Drs., H. Suwarno, M.Pd. Keywords: safety for work, healthness for work, satisfaction and healthness forwork Machine production workshop was a place to perform maintenance, repair and modification of machines, where the manufacture and assembly of machine parts take place. Basically, about (85%) accidents occurred by negligence and human error factors. The company or industry may has a qualified safe conditions for example by providing Personal Protective Equipment (PPE), but the workers did not often want to wear PPE. The reason was, they could not work and move freely.

It was characterized by the t-test results for the experimental group which had a significance level of 0.05 (0.309) on the variable of personal protective equipment. F-test values for each group have significance level of < 0.05 (0.0
