Abstract

PT. Selamat Sempurna, Tbk is a company that manufactures  automotive parts, namely car filters. This filter product has many part numbers. In this company has one of the production lines, namely Line Seat Press Shop, this line produces components from filters, namely seat components. Seat is the main part of the filter component that functions as a filter holder to the engine. This Seat component consists of several part numbers (shapes or variations) following the filter product, and some part numbers handled by the manual engine B070 & L224 will affect the changes in the production engine settings. This production machine includes machines that require time in a slow setup process for switching dies when switching from one part number to another part number compared to other machines, because the element of the process setting is long. With a fishbone diagram, the root cause of the Change Over Part long problem on the machine is from the method category (there is no preparation desk dies and there is not separation of external setup and internal setup). Previously the time needed for Change Over Part was 1961 seconds. After knowing the root cause of the problem and the improvement of the time needed is only 866 seconds. The time difference is 1067 seconds, so save on average time 1095 seconds or 18 minutes / setup. Keywords: Filter product, Change Over part (COP), Fishbone Diagram, Setup, Process Elements.

Abstract

This research is motivated by data showing the productivity of monthly checking of variable speed belts by the finishing department which was only achieved 2 times during the 2021 period. For this problem, researchers conducted research aimed at increasing the results of checking variable speed belts. The objectives to be achieved in this study include: (1) Increase the productivity of the variable speed checking department. (2) Optimizing the existing information management system with the addition of automation features. (3) Knowing the results of the implementation of an information management system that has been optimized for the productivity of checking belt variable speed. The data used are primary data and secondary data. Decision making for improvement is made with the AHP method. System descriptions are done using UML. Analysis of the current system using use case diagrams and system testing using the black box method. The results showed a decrease in the time needed for the variable speed belt checking process from 7 minutes 21 seconds to 7 minutes 6 seconds, so that the checking results increased by 9.19% from an average of 6.91 S / M / H to 7.545 S / M / H. Keywords: Productivity, AHP, UML, use case, black box

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. Keywords : Lean Six Sigma, Product Defect, Production Process, Quality Product, DMAIC, Floor Tile.

Abstract

In designing a company, one of the most crucial aspects to consider is the increasing utilization of Renewable Energy, particularly Solar Energy, as a substitute for conventional electricity. Based on this aspect, the author aims to determine the extent of the business opportunity for the proposed company. The growth of Renewable Energy usage in Indonesia has reached 147.02% in terms of Solar Energy adoption, with the implementation and utilization of Solar Power Plants (PLTS) increasing by 200% during the period of 2020–2024. This study aims to analyze the investment feasibility and business planning projection for a new company, PT. Panel Surya Gama Infinity. The analysis is conducted based on several key aspects, including: industry and competitor analysis using the PESTEL method (Political, Economic, Social, Technological, Environment, and Legal), market and marketing analysis, development of organizational structure and human resources, operational planning, and financial feasibility analysis. Financial projections are analyzed for the period 2025 to 2029 through income statements, changes in equity, balance sheets, and cash flow reports. The results show a Payback Period of 1.81 years, a Break Even Point (BEP) of Rp 8.37 billion, a Contribution Margin of 59.6%, and a Return on Investment (ROI) of 47.11% in the second year. These indicators demonstrate strong business feasibility and effective capital utilization. The company is projected to reach break-even in the second year and is considered financially and strategically feasible to run. Keyword: Business Plan, PESTEL Analysis, Payback Period, Break Even Point, Return on Investment (ROI)
