Abstract

an Research analysis was carried out on designing work tools to avoid musculoskeletal disorders using the Rapid Whole Body Assessment (REBA) method at CV Rama Teknik. Data was collected through asking questions during interviews, and filling out the Nordic Body Map (NBM) questionnaire to ascertain which parts of the body experienced discomfort which could cause a certain level of musculoskeletal disorders. The posture conditions of assembly process workers that can cause musculoskeletal disorders are sitting work posture and standing work posture. The results of the Pick Test observations showed that the frequency of the slouched sitting position was 41 times with a percentage of 46% and the frequency of the upright sitting position was 49 times with a percentage of 54%. The results of the Nordic Body Map questionnaire indicate that the risk level for workers' MSDs is "medium" with an individual score level of 62 for worker 1, 62 for worker 2, and 58 for worker 3. In accordance with the risk level classification based on the total individual score with a score level of 50-70, it is at “medium” risk level. The REBA calculation result for the standing work posture for the first worker is 3, the second worker is 2, and the third worker is 2, so the risk level for the standing work posture for all assemblers is "low", while the REBA calculation result for the sitting work posture for the first worker is 5 , the second assembler is 6, and the third worker is 6, then the risk level for sitting work posture is "medium", according to the REBA risk level if the score is 4-7 then the risk level is "medium". Keywords: Ergonomics Work Design, REBA, Teaching Aids

Abstract

In the early of 2020 the world was shocked by the presence of the Covid-19, a virus with a very rapid spread and became the highest cause of death in the world. Indonesia is among of countries that heavily affected by this virus. Various policies are implemented so that the spread chain of the virus is broken, ranging from work from home, physical distancing to Large Scale Social Restrictions (PSBB). The impact of PSBB is also felt by offline shop owners who are forced to close their shops due to activity restrictions, which causes a loss of income or a drastic reduction in sales turnover. Due to the pandemic, business owners are required to do efforts to adapt to current conditions, one of which is utilizing technology in conducting online sales. Bojong Village, Pondok Terong Subdistrict, is an area that has many private business owners and MSMEs. In regard of the above problems statement, the Community Service Group (PKM) of the Industrial Engineering Study Program at the University of Pamulang held a training on the optimization of online sales during the Covid-19 pandemic for conventional business groups. It is expected that this training can increase the understanding of PKM participants using online sales technology to maintain their business.

Abstract

Work comfort is an important factor in the production process, as it can reduce complaints from workers, especially for handling staff. One of the issues arising from insufficient comfort and safety in the workplace is Musculoskeletal Disorders (MSDs). This study aims to analyze the workers' posture and improve the work system in the oil palm tissue culture production process, using the Rapid Upper Limb Assessment (RULA) method to reduce the risk of MSDs. Based on data from 2022, workers experienced complaints with an average score of 21.92 and a severity level of 13%. This study focuses on evaluating workers' posture during the selection of oil palm shoots and measuring work posture scores using the Nordic Body Maps (NBM) and RULA methods. The analysis showed that 26% of workers experienced pain in every workflow, which needs improvement, with the upper body being the most affected. RULA scores indicated that several operators fell into the high-risk category, with scores ranging from 5 to 7, signaling the need for improvement. As a corrective measure, this study suggests adding portable ladder tools to improve comfort and accessibility for workers, particularly for operators with a height of 145-165 cm and a weight of 50-65 kg. The addition of portable ladders is expected to reduce work strain and minimize the risk of injury for workers. Keywords: Posture Improvement, NBM, RULA.

Abstract

DRA Component Persada is a manufacturing company that produces various types of bolts. The main problem faced by companies is unstable fluctuations in demand, so that sometimes there is a buildup of stock or a shortage of inventory in the warehouse. The aim of this research is to analyze forecasting demand and supply of bolt products at PT. Dra Component Persada. To overcome this, this research uses the Time Series forecasting method which includes Moving Average, Weight Moving Average, and Exponential Smoothing to determine future demand and the Safety Stock method to overcome demand instability. From the results of calculations carried out by the author, the Exponential Smoothing model with a = 0.2 is the optimal forecasting model with the smallest error level, namely with a Mean Absolute Deviation (MAD) of 1,218,085, a Mean Squared Error (MSE) of 1,886,215,000,000 , and the Mean Absolute Percentage Error (MAPE) is 2.74%. The forecast for the coming period is predicted to be 4,440,637 pcs, while the safety stock required is 393,215 pcs with a service level of 95%. It is hoped that the application of forecasting and safety stock methods can increase stock management efficiency and better meet customer needs.
