Manual work activities are more dependent on the operator's ability which still makes frequent Errors. One of the mistakes that occurs is due to human negligence or human Error. Human Error in manual work can result in work accidents. Even if human Error occurs frequently, it can result in a decrease in the efficiency and effectiveness of the company. Lathe activities at PT. C still uses the machine manually. Lathe work activities include the process of installing the lathe tool, picking up the workpiece, setting up the workpiece and the turning process. However, in these activities, there are still many human Errors that occur so that they affect the production of lathes. So it is necessary to improve operator performance in order to reduce human Error. For this reason, it is necessary to identify activities that have the potential for human Error. Work activities are broken down into task levels. Task levels are used as inputs to identify and analyze human Error qualitatively. This method is known as the SHERPA method. This study aims to find out the type of Error in each sub-task of the lathe process and provide recommendations to reduce the human Error that occurs. This research involved all lathe operators at PT. C. and validity is carried out to practitioners to produce consensus. The results of human Error analysis using the SHERPA method found three types of human Errors in the lathe process, action Error, selection Error and information communication Error. So, to reduce the prediction of Errors, it is recommended to train operators, relayout the production floor, increase K3 awareness, increase accuracy and comprehensive communication.

PERBAIKAN METODE KERJA UNTUK MENINGKATKAN PRODUKTIVITAS PADA PROSES PENGUPASAN BAWANG PUTIH (STUDI KASUS: UKM ULAK KARANG PADANG)

Ashila Nurul Huda — Thu, 22 May 2025 00:00:00 +0000

Garlic is one of the most useful and popular types of onions in Indonesia. It has many benefits in
daily life. In Indonesia, especially in West Sumatra, garlic is most commonly used as a cooking spice
in traditional restaurants. Restaurants in West Sumatra typically require peeled garlic since they
lack the time to peel large quantities for cooking. This situation creates an opportunity for household
industries to supply peeled garlic in large amounts. One of the household industries producing
peeled garlic in West Sumatra, particularly in Padang, is Usaha Kelas Menengah (UKM) Ulak
Karang. This business carries out the garlic peeling process using two methods: manual peeling and
machine-assisted peeling. Based on observations using a man and machine process chart, the main
issue faced by UKM Ulak Karang is setup time. The machine is utilized only 15% of the time, while
idle time reaches 85%. Workers spend 76% of their time on setup, 15% on idle time, and 9% on
allowances. The setup time in the garlic peeling process significantly affects daily production output.
Reducing setup time can accelerate the process, allowing production targets to be met. Additionally,
increasing the daily volume of peeled garlic leads to higher income for UKM Ulak Karang. To
address this issue, the Single Minute Exchange of Die (SMED) method was applied directly to
workers at UKM Ulak Karang. As a result, setup time was reduced by 58.29%, and production output
increased by 71.55%

PT Tiga Pilar Sakato is a medium-scale manufacturing company that produces iron poles in Indonesia experiencing problems at the painting station. The problem experienced is that the painting station is in an open space so that the production process is hampered if the weather is rainy. Based on observations in the field, it was found that the posture of the workers' bodies was not ergonomic, causing the risk of complaints and musculoskeletal injuries to workers.

This study uses a participatory ergonomics method, namely active participation from employees at all levels to implement ergonomics programs in the workplace, in this study developing the application of participatory ergonomics in the workstation design process with a design thinking approach through Focus Group Discussion (FGD). The research flow begins with (1) Preparation stage (2) Observation stage and initial data collection (field study) (3) Evaluation stage of existing work stations with participatory ergonomics (4) Workstation redesign stage (5) Analysis stage and (6) Conclusion and suggestion stage.

This study produced a selected design proposal with a spray booth concept that has an operator room with an ergonomic work chair, automatic spray gun, boiler heater to help speed up paint drying and a roller machine to make it easier to rotate the pole when painting. At the design simulation stage, it was seen that the existing ergonomic hazard potential check got a total value of 14 "Dangerous" (Value> 7), after the simulation was carried out for the selected design proposal results, it got a total value of 2 "Safe workplace conditions" (Value <2). This shows that the selected design proposal can reduce musculoskeletal disorder complaints for workers. This study also shows that the participatory ergonomics method based on resource, process and result criteria gets an average value of 4.75 "Good" in the workstation design process.

The joining of ASTM A36 carbon steel plates using the Shield Metal Arc Welding (SMAW) technique is influenced by the tensile strength and hardness of the joint. To improve the quality of ASTM A36 carbon steel plate joints in the future, prediction methods are used. The prediction results play a significant role in determining the quality of the material connection.The method used in this research was descriptive quantitative, by predicting linear regression and non-linear (quadratic) regression models. The purpose of the discussion in this article was to determine the best prediction model for current variations on the tensile strength of future material connections. The analysis of the correlation coefficient showed a strong relationship in both models discussed. This indicates that the current strength variable had a strong relationship with tensile strength. Meanwhile, the highest R-square score was obtained in the non-linear regression model. The determination of the best prediction method was found in the non-linear regression model on tensile strength, with a MAPE value of 3.57%. These results indicate that the non-linear regression model better describes the relationship between current strength and tensile strength in ASTM A 36 carbon steel plate joining.

The rubber industry is an important sector that processes, produces, and utilizes products made from rubber materials, with natural rubber sap as the primary raw material. The industry faces challenges such as mismatched rubber receipt data, which affects production targets due to supply chain disruptions. This study aims to implement Lean Supply Chain at PT A and estimate the efficiency of its application in meeting production goals. The research applies Lean Supply Chain principles to identify and eliminate waste in the supply chain of PT A, from harvesting to storage, using Value Stream Mapping (VSM). The identified waste includes environmental impact, product defects, waiting times, underutilized talent, transportation inefficiencies, excessive movement, and over-processing. Root causes of waste are analyzed using Fishbone Diagrams and the 5 Whys method, followed by corrective actions that align with the identified root causes. The activity mapping process resulted in a 3% increase in production efficiency for Ribbed Smoked Sheet (RSS). Furthermore, Lean Supply Chain implementation reduced rubber processing time from 8 days to 5 days, as per VSM analysis. This study provides valuable insights into how Lean Supply Chain can enhance efficiency and production in the rubber industry.

UPAYA PENGENDALIAN RISIKO BAHAYA PRAKTIKUM DESAIN FABRIKASI PELAT MENGGUNAKAN JOB SAFETY ANALYSIS (JSA)

Thu, 22 May 2025 00:00:00 +0000

Occupational safety and health have a major role in organizations. Occupational safety and health (K3) is a supporting factor for the productivity of an organization. One of the activities with potential danger is in the laboratory which can endanger practitioners during the teaching and learning process due to non-compliance with occupational safety and health (K3) procedures. Such as welding a work object without wearing glasses, thereby potentially being exposed to flames. The plate fabrication design laboratory majoring in mechanical engineering education has many activities carried out, namely cutting workpieces, welding, soldering, etc. Therefore, as an effort to eliminate the risk of work accidents in the laboratory, job safety analysis (JSA) is implemented. The implementation of JSA gives workers a sense of security when working because they can know the dangers that exist in a job so they can take control measures and increase awareness of the importance of K3. Increasing K3 knowledge using Job Safety Analysis (JSA) plays a role in eliminating dangers in the workplace so that work accidents can be prevented. The research results show that the greatest priority risks are in the cutting and welding process, such as injuries caused by sharp objects, exposure to heat, and the presence of sparks. So risk mitigation is needed so that practicum implementation remains safe and efficient.
