Abstract

Fitness centers are the favorite place for most urban communities to do physical fitness training activities. However, among the millions who practice fitness in the gym, only certain people know how to exercise using gym equipment correctly. One alternative solution to overcome the problem is using a personal trainer application based on android. Android-based applications are used in this research because it is easier to use than the physical fitness guidebook and cheaper than hiring a personal trainer. This research recruits ten people to prove increased physical performance after using an android-based application by doing fitness training with and without an android-based application. The test will measure at two conditions. The first condition is that right after fitness training, the respondent will measure physical performance analysis using Nordic Body Map (NBM) Questionnaire and maximum oxygen volume. Second, twenty-four hours after fitness training, the respondent’s physical performance was measured again using NBM and Mc Gill Pain questionnaire to measure Delayed Onset Muscle Soreness (DOMS). After fitness training activities with the android-based application, there is an increase in physical performance and reduced injury potential, which can be seen from a significantly reduced DOMS score from Mc Gill Pain questionnaire. However, NBM score and maximum oxygen volume result are insignificant.

Abstract

There were 47 work accidents at the studied manufacturing company from 2014 to 2016. Thehighest number of work accidents occurred in metalworking processes such as forging and casting,where as many as 22 work accidents, or 46.8% of the total number of work accidents, occurred. So itis necessary to identify the causes of work accidents and control the risk of operational workaccidents. Accidents that occur include being squeezed, bumped, run over, punctured, cut, scratched,hit by an explosion, involved in traffic accidents, and others. So this study aims to prevent these typesof accidents. This study applied hierarchical risk control methodology to provide risk control andreduce the Risk Priority Number (RPN) value for each work activity that has the highest number ofwork accidents. Recommendations that can be implemented are engineering control, administrativecontrol, and PPE control for melting, furan, disamatic, fettling/clearing, and finishing workstations.The results of the proposed risk control resulted in a decrease in the RPN at each workstation.
