Vibration exposure on the hand can cause hand arm vibration syndrome (HAVS). So from that conducted a study to determine the relationship between vibration in the grinding machine in the PPNS tool shop with the possibility of HAVS occurring to the user. The method used is the measurement of vibration on the grinding machine and giving a questionnaire to the sample user. The results obtained showed that vibrations exceeded the NAB (nilai ambang batas / threshold value) which had an impact on the appearance of symptoms of HAVS. So that it can be concluded that the grinding machine in the tool shop requires special recommendations to reduce the level of exposure to vibration to the user. Keywords: vibration, HAVS, PPNS tool shop, grinding machine.

PENDAHULUAN The manufacturing sector is growing rapidly in this modern era. Many important jobs in the manufacturing sector use handheld vibration tools and hand-fed machines such as sanding, grinding, and polishing parts or components of machinery, tooling, sports equipment, furniture, etc. But the tools above can also cause negative effects, one of which is

(HAVS). HSE reported, in Great Britain in 2016 there were 695 new cases of HAVS, with details of 455 cases of Vibration White Finger (VFW) and 240 cases of Carpal Tunnel Syndrome (CTS). Whereas a recent study reported that a significant increase (> 12%) of VFW cases was found in workers who did the grinding and polishing process (Chen et al, 2015). Cases in Indonesia that have been recorded, namely the research conducted by Wahyu (2011) on bajaj drivers in Jakarta with vibrations ranging from 1.05 - 9.22 m / s2

This research is carried out through several stages, which are :

with the most complaints being tingling (38.9%) (Chairunisa, 2017) . PPNS is one of the polytechnic institutions in Indonesia that develops its students to be ready and understanding in facing industrial activities both in Indonesia and globally. Therefore, many practicum around the industry carried out in PPNS to support these objectives, one of which is grinding practice. The grinding process is one of the fairly routine activities carried out at PPNS Tooling Workshop by PPNS students,

a. Study of vibrations (definitions, negative effects, measurement techniques, loads work, NAB vibration, and control techniques). b. Direct observation of worker activities in the field. c. Measurement of vibration in the arms and hands using a vibration meter device. Measurements are carried out in 2 (two) points on the machine that are often in direct contact with the arms and hands. d. Compare the results of the vibration measurements in the field with the NAB in accordance with RI PERMENAKER no. 5 of 2018.

because most of the practicums carried out require grinding in the process to prepare the material. Although there are hazard controls,
