Abstract

Giving excessive workloads causes work stress both physically and psychologically and emotional reactions. The excess workload experienced by drivers and swampers at PT XYZ results in reduced attention at work, decreased work motivation, and decreased skill levels, thus affecting drivers and swampers productivity and the chance of a work accident is very high. This study aims to measure the Mental Workload of Job Driver and Swampers Fuel Tank Using the NASA-TLX Method. The NASA-TLX score obtained 93.8, driver 2 get 83.7, driver 3 91.3, swamper 1 91, swamper 2 89.5, and swamper 3 94.7. Elements of mental workload that are very influential are Mental Demand with a percentage of 22%, Effort 20%, Physical Demand 18%, Own Performance 15%, Frustation Level 15% and Temporal Demand 12%.

Abstract

Coronavirus disease (COVID-19) is a disease that was only discovered in 2019 and has been reported to have spread to almost all over the world. This pandemic has caused anxiety and fear for all Indonesians because it can be transmitted easily through humans. This study aims to cluster each province in Indonesia into certain clusters so that they can find out the characteristics, movements, and government policies that must be carried out in each cluster. This study uses secondary data regarding COVID-19 cases in Indonesia, which reached 4800 data from March 1 to August 11, 2020, in 34 Indonesian provinces. The four variables used were the number of cases of death, the number of cured cases, the number of active cases, and the number of deaths per one million population. Cluster 1 has a high risk because it has the highest variable number of active cases and the number of deaths per one million population. Cluster 2 has a low risk because it has a variable with the highest number of cured cases and the lowest number of active cases. Cluster 3 has a moderate risk because it has the lowest number of cures variable and the moderate number of active cases. The government policy in cluster 1 should prioritize the variable number of active cases and the number of death cases per one million population, cluster 2 must prioritize the variable number of deaths, and cluster 3 must prioritize the variable number of active cases.

Abstract

Musculoskeletal Disorders (MSDs) caused by computer use have become the most common ergonomic risks. The risk experienced can be in the form of financial losses or even lives. Therefore, efforts are needed to prevent the occurrence of ergonomic risks so as not to cause large losses. The Rapid Office Strain Assessment (ROSA) has been designed to identify ergonomic risk factors and is reliable for the assessment of office workers' MSDs. This study evaluates the potential risk of ergonomics in female office workers because a previous study found that MSDs were more common in women. From the two workers observed, it was found that workers 1 and 2 received different scores on several assessment components. The different things are the length of the seat holder, armrests, spine brace, and keyboard. This difference is caused by body posture and different types of chairs. The length of the chair and the spinal brace is influenced by the different postures of the two workers. Worker 1 has a shorter upper leg length than worker 2, so she cannot use the backbone section of the chair. Although there are differences in scores on some components of the assessment, both workers have the same final ROSA score, which is 5. This indicates that further posture assessment needs to be done using tools other than ROSA to detect the specific cause of MSDs levels.

Abstract

This study evaluates the effectiveness of the blood supply chain and determines potential causes of substandard supply chain performance. Unfulfilled demand for blood at UDD PMI Indragiri Hilir in 2021 reached 970 bags, or 14.1% of all orders. The method used is SCOR (supply chain operation references) and CLD (cause loop diagram). The novelty of this research is applying the SCOR model to holistically measure the blood supply chain's performance and determine the leading causes of low performance. The total value of supply chain performance is 77.78, which is a good category. The results show that Five matrices fall into the low-performance process on the Production attribute (28.24), Capacity Utilization Screening (37.50), Capacity Utilization of Blood Quarantine Storage Cabinets (39.01), Capacity Utilization of Healthy Blood (44.44), and Capacity Utilization Crossmatch (33.3). Based on CLD analysis, potential root causes of the low performance of the supply chain with the CLD model are five low-performance matrices on production attributes influenced by voluntary donors and replacement donors, the number of donors, and blood tapping.

Abstract

PT. Pipa Mas Putih is a company engaged in the oil and gas sector. In the production process at PT. Pipa Mas Putih there are still employees who do not pay attention to work procedures, do not use complete PPE, such as not using project helmets, safety shoes, masks, goggles and ear plugs. Until now there are still work accidents. Based on the results of work accident interviews that often occur at PT. Pipa Mas Putih namely, collided, splashed particles in the eye, slipped, squeezed and electrocuted. Hazard and Operability (HAZOP) is a method used to control the risk of work accidents by conducting a risk assessment, which aims to prevent work accidents that can occur. This research was conducted to identify hazard levels that can reduce the level of accidents that can occur in the production area of ​​PT. White Mas pipe. The results of research using the HAZOP method are 1 (one) hazard with very high consequences and 7 (seven) hazards that are classified as having high risk. The steps to reduce the level of risk include providing training to employees and socializing to workers so that they always work according to SOPs and use complete PPE, always carry out toolbox meetings and always prioritize OHS in carrying out work activities.

Abstract

PT Menara Riau Perkasa is a company engaged in the rental of heavy equipment. The maintenance process unscheduled mobile crane heavy equipment is quite long within 5 days including overtime and rest hours and 1 day is inspection. Ordering heavy equipment for 6 days so that the company is often in a hurry for the maintenance process. Therefore, optimization of mobile crane maintenance is carried out by measuring the duration of each maintenance process using the Critical Path Method (CPM). This method is used to identify tasks needed in completing the project and determine scheduling flexibility. This method can complete the maintenance process with an effective time of 2.8 days with 8 hours of operation without rest hours and inspection for 1 day so that the total completion is 3.8 days. The use of the CPM method can reduce the maintenance process time because there are 2 main maintenance process activities that can be done at once with limited leeway time for the battery water process and hydraulic repairs.

Abstract

Stasiun kerja yang pekerjaannya dilakukan secara manual perlu memperhatikan postur kerja manusia agar pekerjaan dapat optimal. Gangguan muskuloskeletal merupakan bagian dari postur kerja yang mana posisi kerja yang salah dan monoton dilakukan terus - menerus akan mengakibatkan kesakitan pada sakit bagian punggung, pergelangan tangan dan kaki dikarenakan proses membungkuk, posisi kaki menyerong, gerakan berulang-ulang dan relatif lama. Pekerja di PT. Toba Pulp Lestari, TBK mengalami gejala seperti itu pada stasiun pembibitan sehingga sering mengalami keluhan. Metode REBA adalah solusi mengatasi keluhan dengan menilai postur kerja saat bekerja dengan menghitung skor pada tabel A dan tabel B. Hasil kedua tabel tersebut akan dimasukkan ke dalam tabel C untuk menentukan kategori tindakan. Terdapat 2 pekerja kategori tinggi dan 1 pekerja kategori sedang yang harus diberikan tindakan segera. Mendesain ulang media pembibitan agar sesuai dengan postur tubuh para pekerja pembibitan dan relaksasi dapat membantu tubuh untuk beristirahat.
