Abstract

The welding process on the AM65511000 type radiator product at PT TRSS in the Curug area is a heavy job that is still done manually. Improper posture and repeated acceptance of static loads for a long period can result in operator fatigue, thereby reducing productivity. The analysis was carried out using Pareto diagrams and fishbone diagrams. Ergonomics analysis with the REBA method is one method to evaluate the overall posture and work attitude of workers. In this study, an analysis of the REBA method was carried out on workers in the welding process section on the AM65511000 type radiator product to determine the risks faced by workers and the improvements that could be proposed. The research was conducted referring to the REBA worksheet by Hignett and McAtamney. From the studies that have been carried out, it was found that workers have a moderate risk with a value of 5 which means that an immediate investigation and implementation is needed in the form of changes in work posture or work environment. The highest risk value was obtained in assessing the bent body posture when moving the radiator. Suggestions that can be made include lowering the level of the holder, optimizing the position of the torso and weight point, and making a table that can be adjusted in height and tilted angle.

Abstract

The development of the business world continues to increase along with the large number of requests for products needed, so it is important for companies to create optimal planning strategies, both production planning and demand planning, so that companies are able to achieve their targeted goals. To achieve company goals, one of the company's activities is to carry out forecasting related to the number of sales or consumer demand for the goods or services produced. PT. XYZ is a developing company whose production results are superior and certified educational toys for children. The analysis used in forecasting is a single 2 period and 3 period moving average method as well as a weighted moving average with weightings of 50,20,30 and 50,25,25. The aim of this research is, firstly, to find out the sales forecasting of playgo type children's educational toys and secondly to find out the most accurate sales forecasting method. The research results show that the method with the smallest error value is the Weight Moving Average method with weightings of 50, 20, 30, where the Mean Absolute Error (MAE) value is 570, the Mean Square Error (MSE) is 447,036, and the Mean Absolute Percentage Error (MAPE) of 1.97%.

Abstract

This study investigates how the Sinar Mutiara SMM in the Karang Serang Village  uses the Blocplan to create a working layout. The aim is to improve operational efficiency by optimizing the configuration of working components such as machines and equipment. The Blocplan method is used to analyze data collected from SMEs through observations and interviews. Research results show that using the Blocplan effectively reduces material distances and production time, and also improves space usage. It is hoped that this implementation will be an example for other SMEs to improve efficiency and productivity. In addition, research finds problems such as adaptation to change and resource constraints. For successful implementation in the future, this issue needs to be addressed.
