The high number of unsafe act prevalence could yield incidents whichcause lose financially to company. The aim of this study is to analyse factors thatcorrelated to unsafe act of workers in preparation and assembling department.This research was conducted in PT X on April to July 2016. These factors dividedinto two categories, personal factors (knowledge, work experience, and educationlevel) and job factors (OHS Information and Supervision). The result shows that72,92% of workers have performed unsafe act in which 61,7% of it is high riskand 38,3% low risk. Moreover, there are siginificant correlations betweeneducation level, knowledge, and availibity of OHS information with unsafe actwhereas education level predominantly contributes to unsafe act after has beencontrolled with other factors. Therefore, company should commit several attemptsto reduce unsafe act on its workers.Keyword : unsafe act, shoes manufacturer, manufactur

Manufacture is one of the industry that has the risk of musculoskeletal disorders. The aim of this research is to analysize the risk factors from the symptoms of disorders of musculoskeletal. This research conducted on March until April 2018 by involving 51 workers on Mixing area and 40 workers on Office Area of X Corporation which is a manufacturing company who made the component of the motor vehicle. This research used Cross Sectional method by using QEC questionnaire and combination of psychosocial questionnaire as the instrument for data collection. The independent variable of this research are the characteristic of workers (age, gender, body mass index, smokimg status, and working time), physical factors on the work place (force, awkward postures, repetitive motion, and coupling) and psychosocial factors (job demands, control of the job, social support, skill discretion, job satisfaction, and work stress). The result of this research shows there is a significant correlation of body mass index with a symptoms on the top of the back, working time and skill direstion with a symptoms of the wrist, high risk of physical factor with a symptom of the neck, and work stress with a symptom of shoulders and the low part of the back. Therefore it needs to be a further control about ergonomic factor at X Corporation.

Risk Level Analysis of Material Manual Handling for Musculoskeletal Disorder's Symptoms to Workers in PT. Pantja Motor Isuzu in 2003.Material manual handlings are significant activities in all kind of industries. Injuries caused by material manual handling are 30% of all kind of injuries (Straker, 2000), usually have impact to trunk (baca injury), it is about 60°% of all kind of injuries. In general material manual handlings injuries are musculoskeletal disorders (MSDs), sprain and strain has a great portion (93.7%) among men workers mostly in manufacture industries. The purpose of this research is to analyse the risk of material manual handling for MSDs's symptoms among workers in the working group of body shop, trimming cabin, and trimming chassis final. This research is a case study with observation approximation. Check list is a tool to assess the risk identification and questioner as another tool to survey the symptoms. The population sample survey includes all labors in those divisions. The population of risk identification consist of three factors such as task characteristic, object characteristic and environment factor during working hour. The result of risk identification is analysed to determine the risk level of task characteristic, object characteristic, environment characteristic and overall. All results were coming from all working group (body shop, trimming cabin and trimming chassis final). The general summary is all working groups have a medium ergonomic risk In general points/overall and job characteristic points, trimming cabin has the highest level of risk Trimming chassis final has the highest risk level of object characteristic points. So, all condition/situation and activities are already having its ergonomic risk lead to musculoskeletal disorders. All working groups have a small number of ergonomic risks compared to working environment characteristic. There are some suggestions to improve such as working procedure/work practice, revision of working space (e.g. distance between material stock and working space, distance between working groups, etc), object/hand tools and administrative evaluation (e. g rotation, work rest cycle, training, etc).
Metabolic syndrome has a large impact on the health condition of workers, this can increase costs incurred by the company and lead to loss of productivity it is necessary to research the risk factors for metabolic syndrome in office workers at PT X which is expected to prevent and control the prevalence of metabolic syndrome in order to reduce risk factor of metabolic syndrome in future. This research was conducted on office workers at PT X with 106 research respondents during February - August 2020 in Jakarta. PT X is an engineering service provider of the Indusrial Automation that has clients in several process industries whose daily activities are sedentary. The design of this research study uses cross sectional method. The aim is to determine the relationship between the dependent variable (individual risk factors and occupational risk factors) with the independent variable Metabolic Syndrome. The results showed that the proportion of metabolic syndrome is 4,97% which the highest metabolic syndrome component was found in high triglycerides 20,4%, low HDL levels is 14,9% and had abdominal obesity is 14,4%. Which had 1 symptom of metabolic syndrome criteria is 25,4% and which had 2 symptoms of metabolic syndrome criteria are 8,3%. Although the analysis found no significant results on the relationship of individual factors and occupation of the metabolic syndrome, but on some individual risk factors such as smoking have a risk of 3,35 times greater than not smoking, and higher education levels 2,44 times higher risk compared to lower education levels.
The development of the industrial sector causes competition to increase productivity. Even though it has developed rapidly, there is always a need for human labor, one of which is in lifting and lowering activities. Lifting and lowering work are one of the jobs that have a risk of Work-Related Musculoskeletal Disorders symptoms (WMSDs This study analyzes the risk factors of WMSDs in stacking workers at PT. X to appropriate control can be carried out, using the NIOSH Lifting Equation (NLE) method to determine occupational factors, individual questionnaires, and Nordic Musculoskeletal Questionnaire (NMQ) to determine the complaint. The design of this observational study was cross-sectional, that involves 43 packing workers at PT.X. The results showed that 55.8% had WMSDs complaints in the last 12 months and 44.2% had no complaints. The statistical test showed that the factor of work/lifting index (p value=0.027) and years of service (p value=0.024) were associated with WMSDs complaints in the last 12 months. So, control is necessary by changing the work design or rearranging work instructions. Furthermore, it is also necessary to control smoking habits and exercise habits.
