Abstract

There are still many work processes that are done manually which require someone to have more abilities in bones and muscles. However, a person's ability is also limited, so that when doing manual work, muscle complaints often occur, namely Musculoskeletal Disorders (MSDs). Activities carried out at PT VWX are still manual, especially in the drum reception and spare part material storage, so there are many complaints in this activity. This study aims to determine the subjective complaints of MSDs, the level of ergonomics risk and the relationship between work posture, age, body mass index, exercise habits and smoking habits on MSDs complaints. The instruments used are NBM questionnaire, work posture pictures and worker characteristics questionnaire. The NBM questionnaire showed that subjective complaints were mostly felt on the back with a score of 35 (87.5%). The method used is the REBA method with the calculation results having a high level of risk, namely in the drum reception section an average score of 9 and in the spare part material storage section an average score of 8.3. Based on the results of research tests related to MSDs complaints are work posture, age and body mass index, with a significance value of <0.05, while those that are not related to MSDs complaints are exercise habits and smoking habits, with a significance value of > 0.05.

Abstract

ABSTRACT The goal of this research was to look at the intensity of machines and equipment in areas one and two of production, as well as the impact of machines and equipment on job weariness at PT EOB. Area one has the maximum intensity of production created by machinery and equipment at 109 dBA, whereas area two has the highest intensity at 103 dBA. A production questionnaire was sent to all operators in the sampled region in addition to utilizing tools to estimate the noise level received. The job tiredness level instrument, on the other hand, has an average score of 27.15, with a proportion of weariness of 75%. The value of r = 0.794, as determined by statistical tests utilizing Person Correlation, indicates that there is a reasonably strong correlation and close association where the value of r is in the range of 0.61-0.80. This indicates that the more work tiredness there is, the more work fatigue there is. The test yielded a 0.05 probability significance. As a result, it may be argued that H0 is rejected and H1 is accepted, implying that noise has an influence on job weariness.

Abstract

In all industrial activities, the role of humans as a source of labor remains dominant. Unlike cars that can be repaired and replaced. Whoever is an employee still has limitations. In manual labor, people are at a greater risk of contracting MSD, which can lead to unsafe working conditions. Practice lifting a drink box in your CV. The AUDIO NEW LIGHT can be dangerous when lifting drawers due to manual and unsanitary working positions. The study has an average REBA occupational risk score of 8 in the high category for neck, back, waist, larynx, thigh, left arm, left and right wrist, right, indicating that immediate action is required. An approach to avoiding these risks when designing trolleys is to use EFD technology based on ENASE ergonomic considerations.

Abstract

ABSTRACT Many work error that occur are caused by human themselves, which are called human error. Human error that often occur in production activityes can harm thet company in achieving production effectivenes and eficiency. Therefore, it’s necesary to improve the performance of workers in order to reduce work error that often occur. Several methods for identifying human errors in clude the SHERPA and HEART methods. SHERPA is a qualitative human errors analysis method that uses task level as the basic input. HEART, on the other hand, is a quick, easy and accessible way to determine the risk of human error. PT Duta Logistik Asia is one of the companies that produces activated carbon in the city of Batam. The activated carbon process goes throuh several stages, namely the heating proces, the sieving process, and the packaging process. Based on the information obtained from the company, errors often occur when doing work which greatly affects the safety of workers and production output as a result of human error. Finding recommendations that are needed to reduce error in the activated carbon production proces using the SHERPA method are to carry out regular and thorough inspections and work on each process and provide periodic training to employees. The probability of error in every work activity in the activated carbon production process using the HEART method wherye the largest nominal human error probability value is 0.16. The process that may occur in human errors in the activated carbon production stage at PT Duta Logistik Asia is through the highest Human Error Probability (HEP) value of 0.544 which is found in the heating and packaging process of activated carbon.
