Abstract

CV. Insani Production is a business operating in the decoration rental sector which has been established since 1998. However, with the development of technology today, competition in the industrial world in the service sector has become increasingly intense, making competition in the service sector increasingly attractive. That way, his rivals are not only where he stands, and his rivals are no longer limited to a region, city, or even country. The resulting effect of this makes competition increasingly fierce between providers of event decoration and sound system rental services. So, it requires developing services not only to keep up with the times, but also to be able to compete in an era where all limited information no longer exists. CV. Insani Production experienced a decline in turnover due to a lack of development in service quality from year to year. Researchers help owners to overcome this by using the servqual, kano, and kansei engineering methods. Researchers use this method to find out what customers really want, so they can fulfill customers' current needs.

Abstract

PT XYZ is a multinational company operating in the Fast Moving Consumer Goods (FMCG) sector. The existence of one of the production lines which frequently experiences downtime means that the Company is unable to maximize the fulfillment of consumer demand. This research aims to enhance the efficiency and effectiveness of machine equipment particularly focusing on Line 2 in bar soap production. In this research, an analysis was carried out using Overall Equipment Effectiveness (OEE) and Six Big Losses methods as the basis for the calculation. The stages in this research are identifying the cause of the problem using a fishbone diagram and the 5 Whys technique, as well as designing a repair solution using the PDCA cycle. The results of this research show that The average suction cup setting for the period August 2023-February 2024 before repairs were carried out was 1.68% affecting OEE, and after repairs were carried out for 3 weeks it managed to decrease to 1.37% with a difference of 0.31%. The calculation of Overall Equipment Efficiency (OEE) results has increased from the average for the period August 2023-February 2024 before the improvement was 60.10%, then improvements were carried out for 2 weeks and managed to increase to 64.20% with a difference of 4.10%.

Abstract

CV. Karya Cipta Baru is one of the companies operating in the remanufacturing industry for heavy-duty vehicles such as trucks, trailers, and others. The company is planning to invest in electric welding machines to expedite the process of repairing truck trailers. Feasibility analysis and productivity analysis will be conducted to determine the viability of this investment. Sensitivity analysis is performed using the NPV calculation method, resulting in an NPV of Rp. 157,491,591. The calculation of PP estimates a payback period of 4 months and 18 days. The IRR calculation yields an investment return rate of 234%. And the PI calculation shows a profitability index of 8.16. Productivity analysis is also conducted using the Marvin E. Mundel method to assess the impact of the investment in electric welding machines. From the productivity analysis results, the investment is deemed feasible as it can increase the company's sales and net profit

Abstract

Risk is a factor that always exists in every sector of life incluidng suppky usage in PT KAI. Based on the results and discussion of this research, the conclusion is that there are 20 risk agents and 20 risk events, of which 4 priority risk agents are lack of control over fuel hoses (A13), inaccurate measuring instruments (A7), Over limit Policy (A2) and lack of clear and measurable coordination (A1). Second, there are 6 mitigation actions, namely Modification of the queue and filling system (P1), Improvement of the train supervision and monitoring system with (P2), Training and coordination staff ( P3), Training of machinists and system machinists and managemen update (P4), Modification of fuel control data with by internet (P5), and Maintenance engginer properly and scheduled ( P6). Where the most effective solutions based on HOR Phase 2 are respectively PA 2, PA 3, PA 4 PA 6, PA 5 and PA 1. Meanwhile based on AHP they are PA 2, PA 1, PA 5, PA 6, PA 3 and PA 4. So the alternative solutions developed are PA 2, PA 3 and PA 4.

Abstract

This study investigates the feasibility of investing in additional logistics fleets at PT XYZ, a manufacturing company based in East Java engaged in the production of rice and glutinous rice flour using imported raw materials. The complexity of distribution in the context of growing demand from MSME customers has caused operational problems in the form of late deliveries and backlog orders due to the limited number of available fleets. To overcome these problems, this study applies a quantitative approach based on investment analysis techniques, including Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period (PP), and Sensitivity Analysis. Primary data were obtained from field observations and interviews, while secondary data came from the company's logistics records for the period November 2023 to January 2024. The results of the analysis show that additional fleets have a significant impact on improving service quality and distribution cost efficiency. The NPV and IRR approaches indicate that the investment is financially feasible, with a positive NPV value and IRR exceeding MARR. Meanwhile, the Payback Period is within a reasonable payback period according to the economic life of the fleet. Further sensitivity analysis confirms that variables such as operating costs and annual income are the main determinants of investment feasibility. These findings provide a strategic basis for data-based logistics investment decision-making, while strengthening the company's competitiveness in meeting customer expectations amidst competitive market dynamics.

Abstract

This research investigates the quality control system for iron pipe products at CV. XYZ through the application of Statistical Quality Control (SQC). Recognizing the critical role of quality control in ensuring product standards and customer satisfaction within manufacturing, the study employs SQC methodologies, including control charts, Pareto diagrams, and fishbone diagrams, to analyze production process variations. Production data on iron pipe defects over a specific period November 2024 to May 2025. The analysis revealed prevalent defect types and indicated a statistically uncontrolled production process. Consequently, the study recommends a thorough evaluation and improvement of the underlying processes contributing to quality issues. Consistent implementation of SQC is projected to enable CV. XYZ to enhance product quality, minimize defects, and improve overall production efficiency.
