Abstract

A risk of musculoskeletal disorders (MSDs) due to non-ergonomic work postures was found in herbal medicine sellers. This study aims to analyze the posture and ergonomic risk levels using RULA, REBA, and Nordic Body Map (NBM) through observation and interviews with three respondents (aged 21, 33, and 63 years) who work an average of 2–3 hours per day with a load of 7 kg. The results of the study using Rula and Reba showed that the work posture was not fully ergonomic, with Rula values ​​of 4 and  Reba  values of 9. RULA and REBA values ​​indicate a moderate to high risk level, especially in elderly respondents. Although there have been no significant musculoskeletal complaints, the potential for musculoskeletal disorders can increase if work habits are not immediately corrected. It is necessary to apply ergonomic principles such as using a more ergonomic carrier (wide and soft straps), adjusting the load balance, taking active breaks and stretching, using alternative pushing aids (trolleys) on flat areas. Overall, the workload is still considered safe according to metabolic energy, but body efficiency decreases with age. Keywords: Ergonomics, Herbal Drink Seller, NBM, RULA, REBA

Abstract

Sustainable organic waste management is a crucial issue considering the serious negative impact of landfilling. Although organic waste has great potential to be processed into compost or eco-enzymes, small-scale conventional shredders often face obstacles such as low efficiency, monolithic structures, and reliance on the power grid, which hinder adoption at the communal level. This research aims to optimize the productivity of organic waste shredding machines with a capacity of 20 kg/hour through design modifications. The methodology applied is experiment-based Research and Development (R&D). The modifications made include the implementation of a modular design (dismantling) to overcome logistical constraints and the conversion of the drive system from an electric motor to a 6.5 HP gasoline motor to ensure independent operations at the site. Comparative performance evaluation was measured using the Marvin E. Mundel Productivity Model. The test results show a significant improvement in performance. The modified machine achieved a Productivity Index (IP) of 1,579, reflecting an increase in production effectiveness of 57.9%. This increase is also supported by processing time efficiency of 36.7%, reducing the enumeration time of 5 kg of waste to 19 minutes. In conclusion, design modification strategies that focus on adapting energy sources and improving mobility are very effective in producing appropriate technologies that are efficient and ready to be implemented in society.

Abstract

Improving customer complaint handling is crucial for the sustainability and success of a business, as efficient and responsive complaint handling demonstrates a company's commitment to meeting customer needs and expectations, thereby enhancing customer satisfaction. The automotive industry sets a 14-day working day standard for complaint resolution. However, the actual complaint handling process often takes an average of 26 days. By implementing a traceability system, integrating a Value Stream Mapping (VSM) approach, and adopting Industry 4.0 transformations, this research aims to reduce the handling time. Moreover, by mapping the workflow through Visual Stream Mapping, inefficiencies can be identified, and through the implementation of a Traceability System and the development of system-based processes, the transformation achieved through the conceptual model of Industry 4.0 adoption can improve the process from 26 working days to 7 working days. Keywords: Customer Complaint, Traceability, VSM

Abstract

Over the past four months, PT KLM has experienced discrepancies between logistics delivery targets and actual performance, both through truck and train modes. This underachievement is suspected to be related to the suboptimal productivity of logistics staff due to weak leadership and an unsupportive work environment. This study aims to analyze the influence of leadership (X1) and work environment (X2) on the work productivity (Y) of logistics staff at PT KLM. A total of 60 respondents were selected using simple random sampling technique, and multiple linear regression was the methodology used. A questionnaire was utilized to collect data, and SPSS software was employed for analysis. The results indicate that partially, neither leadership nor work environment has a significant impact on productivity. However, simultaneously, both have a positive and significant impact on the productivity of logistics staff with an adjusted R square value of 10.3%. These findings highlight the importance of synergy between leadership and the work environment in enhancing productivity. In relation to these findings, strategies for improving operational performance need to focus on strengthening both aspects in an integrated manner. Keywords: Leadership, Productivity, Work Environment.

Abstract

The quality of footwear products such as shoes is a major factor that influences the success of a company in producing footwear products. Shoe companies usually have various quality control methods to maintain the production process. One of the most widely used methods in the industry is the statistical quality control method. PT ABC is a company that produces sports shoes located in Bandung. ABC Company is experiencing problems in terms of production, namely the number of defective products produced is still high. This study aims to apply statistical quality control to control the number of defects that appear in the production process. The application process is focused on the problems that arise in the screen printing division where there are many defects that appear during the production process. The steps taken in this study include data preparation and initial analysis using check sheets and Pareto diagrams, data adequacy tests, making p control charts, and analyzing results. Based on the control chart that has been made on the initial defect proportion and the proportion of defective data after improvements have been made to the screen printing process, it can be concluded that there is a decrease in the average value of the defect proportion of 0.02. This figure is quite significant. In addition, there was a drastic decrease in the LCL (lower control limit) value. This significant decrease is a positive indication that the improvements made to the screen printing process have succeeded in reducing product defects significantly.

Abstract

The intense competition in the printing industry demands companies to improve efficiency, particularly in managing raw material inventories. PT. JKL faces challenges in controlling paper inventory, including excessive stock reaching up to 32,000 kg per year and inefficient ordering and shipping costs due to mismatches between order quantity and truck capacity. These issues lead to increased costs and the risk of stockouts or overstocking. The purpose of this study is to identify the most efficient quantity and schedule for paper ordering while keeping overall inventory costs low using the WWA (Wagner Within Algorithm) method. A quantitative approach is employed, involving demand forecasting, WWA calculation, safety stock, and reorder point analysis. The results indicate that implementing the WWA method can reduce the number of orders from 24 to 12 annually and achieve inventory cost savings of Rp 375,368,025. Additionally, the company can maintain a safety stock level 3,411 kg and a reorder point set of 13,204 kg. Thus, the WWA method is effective in addressing PT. JKL’s inventory control problems and can be adopted as a strategic tool for operational efficiency. Keywords: Demand Forecasting, Inventory Control, Inventory Cost, Wagner Within Algorithm

Abstract

High and continuous production processes inevitably generate large amounts of production waste. PT RPG is facing problems, especially with the warehouse used to store production waste which holds 17 types of waste. The warehouse is very small, with an area of only 16 m², so it cannot accommodate all 17 types of waste. This causes difficulties in waste placement activities, creates an irregular layout, and increases the risk of work accidents. The purpose of this study is to redesign the waste warehouse in order to reduce the risk of work accidents using the Class-Based Storage method and the 6S approach. This research is quantitative and involves steps such as frequency calculation, cumulative frequency, ABC classification, proposed 6S design, and proposed 3D layout model. The results showed that the warehouse area was expanded from 16 m² to 40 m², which improved the layout for material movement based on the Pareto 80/20 principle used in the ABC classification. In addition, there was a 46% increase in the efficiency of waste placement time, which supported more effective waste handling and retrieval, ultimately reducing the risk of workplace accidents. Thus, the Class-Based Storage and 6S methods proved effective in addressing the layout and safety issues at PT RPG's warehouse. Keywords: CBS, Layout, Warehouse, 6S
