Health status of workers are crucial to maintain their productivity and it will impact on output per capita. This systematic review aims to evaluate the effectiveness of nutrition and health intervention in workplace setting and implication for further research. Articles were searched from PubMed, PMC, Cochrane Library (Trial), Science-direct, and Google scholar published from 2005-2020. Inclusion criteria was the intervention subject aged 19-64 years old with experimental randomized control trial (RCT) or non-RCT study design. Several keywords used for literature searching including “nutrition education in workplace”, “nutrition intervention in workplace”, and “workplace intervention”. Data were narratively described. Eleven studies were meet inclusion and exclusion criteria and further be reviewed. Five studies focused on intervene food environment in the workplace, four studies focused on nutrition education using different channels i.e., workplace visiting and emails, the other two interventions were objected to decrease health risk regarding occupational health. Positive outcomes were recorded for all workplace intervention, including increase in nutrition knowledge, self-efficacy, reduce risky behavior, and also improved body mass index and blood biomarkers. Workplace nutrition and health intervention proved to be an effective way to enhanced balanced nutrition behavior and improve health status. This study implies an urgency of nutrition and health intervention in a workplace.

Lack of involvement in interventions to carry out observations and analysis that causes the conditions and behavior of employees at one of the logistics companies at the Jakarta branch. The research aims to reduce potential unsafe of conditions & unsafe actions in the workplace environment. This process involves employees recognizing potential problems in the workplace within the procedures of observation, feedback, and employee behavior interventions. The methodology used in this study is a descriptive method to describe present or ongoing issues. This method allows for assessing a condition and program implementation to make further improvements in the future. There are still several obstacles in implementing the K3 Program (Safety, Health, and Environment), where the program is still being performed manually. BBS STAR program does not cover unsafe conditions and unsafe actions, so reporting workers to management regarding conditions at work still not optimal yet. Employees also have some difficulty reporting unsafe conditions and unsafe actions in the workplace. SEWS program can be a preventive step in the occurrence of potential danger. The quality of employees could increase with the habit of analyzing dangerous aspects of the workplace environment. Emplo yees' involvement in the SEWS contribution program can also help establish moral consistency.

Background: Repair and maintenance work of machine has high risk and hazard that could potentially lead to work accident. The use of PPE is the final hazard control effort that serves to reduce the severity of work accident5. This study analyzed the effect of age, self-efficacy, PPE training, and PPE availability on substandard practice of PPE usage in maintenance workers. Materials and Methods: This study was an observational study with cross-sectional design. Subject of the study amounted to 54 maintenance workers. The independent variables were consisted of age, self-efficacy, PPE training, and PPE availability. The dependent variable was substandard practice of PPE usage. Data collection techniques used questionnaire to find out age, self-efficacy, PPE training, PPE availability, and observation to know substandard practice of PPE usage. Result: The p value of age = 0.021, the p value of self-efficacy = 0.089, the p value of PPE training = 0.000, and the p value of PPE availability = 0.345. Based on multiple logistic regression test, if (p < 0.05) hence it has a significant influence to substandard practice of PPE usage. Conclusion: self-efficacy and PPE availability have no effect on substandard practice of PPE usage. Age and PPE training significantly affect the substandard practice of PPE usage in maintenance workers

Introduction: Ear protection equipment is indispensable for workers exposed to noise exceeding the threshold value. Introduction: Many studies have shown that the level of labor compliance with the use of ear protection equipment is influenced by the length of work and age of the workers concerned. However, many studies also show different conditions with the results of these studies. For this reason, this study was conducted to determine how the influence of the work period and age of workers on the compliance with the use of ear protection equipment at PT X animal feed industry. Methods: The method used was observational with a cross-sectional approach. The number of population selected from animal feed production workers was 30 workers. The sample was obtained using a simple random sampling calculation of 28 workers. The analysis was done using contingency coefficient statistical tests. Results: The number of workers in the study area whose tenure <12 years is 50% and whose age <37 years is was also 50%. By using the contingency coefficient, it is known that there are 39.3% and 35.7% of 64.3% of workers who were not compliant with the useof ear protection equipment, each having a work period of <12 years and age <37 years respectively. It is also known that work period and age of workers have a Sig (0.115)> α (0.05) and Sig (0.430)> α (0.05) accordingly, which means there is no relationship between work period and the age of the workers with the compliance with the use of ear protection equipment. Conclusion: The reasons of the non-compliance of workers with the use of ear protection equipment are they feel uncomfortable, they have a lack of supervision, as well as they have a lack of motivation work.age, animal feed, compliance, ear protection equipment, years of service
