Abstract

The Full Time Equivalent method is used to complete various jobs against the effective working time available. To get the FTE value of a work process must use Work load Analysis calculations using the equations of total activity time, allowance, and total available time. From research, it is known that overload workloads exist on fine boring workstations. The total number of FTE values on fine boring workstations is 1.38. Underload workloads are Clean Spatter 1 &; 2 stations and QC Inspection. At Clean Spatter stations 1 &; 2, the workload result for operator 4 is 0.46 and operator 5 the workload result is 0.48. For QC Inspection workstations, the workload result obtained is 0.89. From the results of workload equalization, the result is obtained that the total workload can be done with 6 operators. The workload balance value increased from the previous 76% to 88% or an increase of 12%.Keywords: Full Time Equivalent, Work Load Analysis, Allowance, Production process, Cycle time

Abstract

This study aims to determine the root causes of waste in the reactor washing process and blending tank in the Department Production 2 PT. Pardic Jaya Chemicals which causes excessive costs or expenses if it is not identified what is the main cause of the problem. The research method used is root cause analysis (RCA) with Cause and EffectAnalysis or Fishbone Diagram. The results of the root cause research found several main factors, including differences in perception, limited tools, contaminated air and the character of the resin that was too solid. Proposed improvements to overcome this problem are by refreshing the work instructions, replacing the washing solvent with ethyl acetate by using distilled ethyl acetate (ETAC Ex-Dist) and adding N2 gas (Nitrogen) into the washing solvent. Keywords: Waste, Root Cause Analysis, Fishbone Diagram, proposed improvement plan, solvent

Abstract

This study aims to improve the productivity of the weight scale production process by using the Objective Matrix (OMAX) Method supported by Fishbone Diagram analysis and the 5W+1H approach. The weight scale is an important tool in various industries, so effectiveness and efficiency in the production process are very important. In this study, Fishbone Diagram is used to identify and analyze the main causal factors that affect productivity, such as people, machines, materials, methods, environment, and measurement. After observation, there are four factors that cause a decrease in productivity of weight scale products, namely human factors, materials, methods and machines. The 5W+1H approach was then applied to formulate appropriate improvement solutions based on the identified causes. The OMAX method was used to measure and monitor the effectiveness of the proposed improvements. The results show that the integrated application of these methods can reduce production cycle time, improve product quality, and increase overall productivity. This research makes an important contribution to the development of productivity improvement strategies that can be applied in various manufacturing sectors. Keywords: Productivity, Objective Matrix (OMAX) Method, Fishbone Diagram, 5W+1H, Process improvement

The data used in this research is data on daily fructose consumption at PT. API during the period May 2023 to May 2024. The methods used in this research are descriptive analysis and statistical analysis. Descriptive analysis is used to describe fructose consumption data, while statistical analysis is used to determine appropriate inventory control methods. The research results show that the fructose supply at PT. The API is not well controlled. This is indicated by high fluctuations in fructose use and suboptimal supply levels. Keywords: Fruktose, Inventory control, Safety stock

Abstract

PT. Prisma Engineering Unggul is an engineering company and manufacturer of engineering transportation equipment, designing and manufacturing engineering products specifically for off-road applications used in the mining, oil and gas, agroforestry and transportation sectors. Production machine layout at PT. Prisma Engineering Unggul has not followed the layout of the production area in accordance with the flow of the material handling process. So the machines are still very close together or far apart, so that a lot of materials and products are scattered about in the wrong place, causing buildup and making it difficult to walk in the production area. Objectives To find out the best spacing layouts for arranging production machines using the systematic layout planning (SLP) method and ARC (Activity Relationship Chart),ARD (Activity Relationship Diagram tools using field study methods, linear studies, brainstorming (brainstorming/feedback). Based on the method (SLP) can determine the relationship between the activities of the relationship between machines can produce machine layout to be based on production flow. For the proposed layout of the machine distances that have been made, it can be seen that the machines are neater in sequence with the flow of material. So that the activity of moving material is lower and the total time is relatively short, production results can also be placed not scattered and make it easier to walk in the production area.Keywords : SLP, ARC, ARD, Layout, Machine Distance.

Abstract

The main objective of this study is to identify and reduce product defects occurring during the production process. Data was collected from January to December 2023, with an initial defect rate of 8.65%, equivalent to 86,500 defects per million opportunities (DPMO). Through the application of the Lean Six Sigma method, the defect rate was successfully reduced to 6.16%, or 61,600 DPMO. The initial Sigma level was 3.82 and increased to 4.10 after improvements. This approach involves several key stages: Define, Measure, Analyze, Improve, and Control (DMAIC). In the Define stage, the problem is clearly defined, including identifying the most frequent types of defects such as cracks, surface blemishes, and size variations. In the Measure stage, data is collected and analyzed to identify problematic areas, using statistical tools like histograms, Pareto charts, and control charts. In the Analyze stage, an in-depth analysis is conducted to find the root causes of defects through methods like the 5 Why's and fishbone diagram. In the Improve stage, solutions are implemented to address the root causes, such as adjusting machine parameters, retraining employees, and enhancing raw material quality. In the Control stage, steps are taken to ensure that the improvements made can be sustained in the long term by implementing regular monitoring procedures and quality audits.

Abstract

In line with technological advancements and increased consumer expectations, quality has become a key factor in the service industry. PT. XYZ, which operates in the aircraft maintenance field, faces the challenge of reducing defects in the aircraft painting touch-up process. This research aims to reduce these defects using the DMAIC method. The DMAIC phases include define, measure, analyze, improve, and control. In the define phase, it was found that dust defects were the most dominant. Initial measurements showed an average DPMO (defects per million opportunities) of 12,129 and a sigma of 3.773. Analysis using the Ishikawa diagram identified the root causes of the problem, and FMEA helped determine the priority root causes that needed immediate improvement. The main causes of the aircraft paint touch-up defects were material cleaning that left fibers on the surface to be painted, and the spray gun being in an un optimized condition for use. Suggested improvements included procuring the appropriate cleaning materials and implementing a preventive maintenance checklist for the spray gun. The implementation of these improvements showed a reduction in dust defects, with the DPMO dropping to 3,477 and sigma increasing to 4.209. These results demonstrate that the improvements made were effective in reducing defects and enhancing painting quality.Keywords: DPMO, sigma, DMAIC, dust defects, aircraft painting.
