Abstract

PT Amtek Engineering Batam is a manufacturing company that has a vision that emphasizes quality and productivity in order to remain superior in today's global business competition. PT Amtek Engineering Batam has a machining section that functions to manufacture component or part tooling, assembly components, automotive and machine auxiliary tools with various work processes, namely CNC wirecut, CNC milling, EDM, grinding and jig grinding processes. The basic materials used are copper, hard rass, high speed steel, aluminum, DC 11, Carbide and ASP 23 to produce tooling components which are an important part of stamping machines. Section machining has a make to order production system, where in one working day there are different requests and needs. Apart from that, other things also shappened when lifting the dies to the mazzak CNC milling conveyor, workers used a hoist crane, where when installing the elbows on the dieshoe the worker's body position was squatting so that from interviews conducted with several workers, workers often complained of pain in the workers' feet and hands . The problems above can be solved by creating a good work environment using the 5S method then conducting MSDs questionnaires to find out workers' pain complaints and measuring worker body anthropometry data to find percentile data from workers then designing tooling cabinets using Autocad by looking at the results of measurement data anthropometry. The result of this research is an ergonomic tooling cabinet design

Abstract

The purpose of this study was to determine the physical work environment conditions felt by employees in the moulding section, determine the level of burnout of employees in the molding section and determine the relationship between the physical work environment and the fatigue of employees in the molding section. This research was conducted at the molding department at PT ABC. The population in this study amounted to 50 employees of the molding department at PT ABC. The results showed that: 1) Based on the results of measurements of the room temperature variable, the average value was 20.14 with a percentage value of 72%, it can be concluded that molding employees at PT ABC experience excessive heat while working. This category is not good enough that it causes work fatigue to occur, 2) Based on the measurement results of the work fatigue variable, 37 respondents experienced moderate fatigue and 6 respondents experienced mild fatigue with an average of 77.6 with a percentage of 65%. It can be concluded that molding employees at PT ABC experience fatigue with middle and upper levels at work. This is caused by the unfavorable room temperature which causes work fatigue in employees, and 3) Based on the results of the influence test measurements, it shows that room temperature has a significant effect on the work fatigue of molding employees at PT ABC.

Abstract

Now it has become a tendency for every parent to bring their baby in all their activities from shopping to malls or traditional markets and not even a few who take their babies while doing work outside the home. many parents wanted a multifunctional pillion chair. One way to do this is to identify what the customer wants and develop pillion chair products using the Quality Function Deployment (QFD) approach. the design concept of the added child pillion chair is to be multifunctional. The multifunctionality in question is that the child's pillion chair has been developed to become a stoller as well so that parents who have children 1-3 years old when traveling using two-wheeled vehicles are not tired of carrying their children. The development of this pillion chair is also based on ergonomic aspects by using the anthropometric method of measuring the child's body. The results of the ergonomic analysis of the child pillion chair using anthropometric calculations are that the seat width is 29cm the seat length is 22cm the backrest height is 31cm the armrest height is 18cm the footrest height is 24cm the seat belt length is 33cm.

Abstract

The piercing mill machine is one of the machines used by the company PT Rainbow Tubulars Manufacturing in producing Oil country Tubular Goods (OCTG) seamless pipes. The work process in operating the piercing mill machine includes sprinkling salt and pushing the pipe directly exposed to high heat, noise, smoke and extreme dust. The company has established controls such as Personal Protective Equipment (PPE) and Occupational Safety and Health (OSH) training, but these control efforts have not been maximized, due to a lack of awareness and compliance in using Personal Protective Equipment (PPE). The purpose of this study is to identify the risks of operating a piercing mill machine using the Job Safety Analysis (JSA) method, calculate and analyze the value of the risk, and provide recommendations to the company. Research data was obtained by documentation, observation, interviews, and discussions with production supervisors and OSH experts. The results of this study obtained four job structures and 27 work stages and 31 sources of risk. There are three very high risks, including splashing of billet material with high temperatures, exposure to heat, dust and high noise. providing tools such as replacing tools that are no longer suitable for use.

Abstract

In Employees who perform welding are often exposed to heat sources, including sunlight and heat from welding machines because some employees perform welding outdoors. Cutting iron, heating, grinding, joining, painting and sanding are steps in the welding process that are performed in a work environment exposed to sunlight. Thus, the question of whether fatigue has an impact on employee performance at PT Mcdermott Batam must be answered. A person's fatigue level can be assessed by several methods, including subjectively using the Industrial Fatigue Research Committee (IFRC) questionnaire. The level of fatigue is assessed using this questionnaire. At PT Mcdermott Batam, employee performance is assessed using a questionnaire which is prepared based on employee performance criteria. The objectives of this study are to determine the level of employee fatigue using the IFRC method, to determine the level of employee performance in the welding section and to determine the level of relationship between fatigue and employee performance. This study uses simple linear regression test. The results showed that there is an influence between job fatigue on employee performance.

Abstract

Ergonomics is the art, science, and application of technology used to balance the environments in which people work or rest with their physical and psychological capabilities and limitations so that the overall quality of life can be better. High demands on Material Handlers at PT XYZ are required to complete the delivery of goods on time, where in a survey conducted by Material Handler employees spend 65% of their time completing the delivery of goods. Work like this is associated with several ergonomic risks, especially the risk of musculoskeletal disorders. For precisely determining worker posture, REBA or Rapid Entire Body Assessment is a helpful technique. The highest number of respondents a total of 23 reported experiencing waist pain in the questionnaire's results for the 8 workers. with a 71.87%. Then the next largest number feels pain in the hip with a total of 22 or 68.75%. Furthermore, they felt pain in the upper right arm as much as 21 or 65.62%. It can be concluded that Material Handler activities can cause musculoskeletal disorder injuries.

Abstract

This study aims to analyze the risk level of Musculoskeletal Disorders (MSDs) in workers who carry out Manual Material Handling (MMH) activities at PT JMS Batam. MMH is a manual transportation and material transfer activity using human labor. This study was conducted because MMH activities carried out repetitively often cause health complaints, especially in the skeletal muscles. The primary data collection method is carried out through observation, direct interviews with employees, documentation using mobile phone cameras, and the distribution of Nordic Body Map (NBM) questionnaires to identify complaints on workers' body parts. The Rapid Entire Body Assessment (REBA) method is used to assess the posture of workers during MMH activities. The results showed that Nordic Body Map analysis showed that all stevedoring workers had the potential to experience musculoskeletal disorder complaints, especially on the left shoulder, right shoulder, back, waist, and buttocks. Workers with scores above 70 are at high risk and need immediate improvement. Workers scoring 55-70 are at moderate risk and require consideration of future improvements. Analysis using the REBA method showed that material transfer has a high risk of trunk and upper arm posture, increasing the risk of injury and health problems.
