Abstract

Kandayas Furniture is one of the companies engaged in manufacturing tables. The table production process goes through several stages. Based on field observations and interviews that have been conducted, problems arise from the company's production process. The problem exists in the assembly process because many products are waiting, so there is a buildup in the assembly process of the table. The buildup occurs because the assembly process to the finished material warehouse has a considerable distance difference. This resulted in an ineffective production process. Then, in Promodel Now the movement of each work station still uses human labor which results in delays in the production process. From this problem, it is obtained that the process flow changes are more structured, the material handling distance from assembly to finished goods is shorter because there are changes in the lay out that we propose and make material handling time more efficient, using handlift conveyance in each flow, adding assembly operators due to bottlenecks in assembly due to the paint drying process, using a paint oven machine for drying paint to shorten the time and reduce the accumulation of goods, and implementing K3 according to the SOP so that employees avoid work accidents. Keywords: Bottleneck; Productivity; ProModel Software; System Simulation

Abstract

Project scheduling is a method of arranging a schedule of tasks to be carried out to realize or achieve certain goals, by filling in a table of the time needed to complete. Critical Part Method (CPM) is a program method that can calculate the time needed to complete all activities and determine which ones the project implementer should pay attention to to ensure they can be completed as planned.  The purpose of this study is to identify the critical path to which critical activities are included, as well as evaluate the scheduling between the project owner's planned time and the duration of the planning outcome. In the construction project of a gym with a land area of 60m (5 x 12m) in Mustika Prakarsa Block C Housing, Cibalongsari Village, Klari District, Karawang Regency, 41371. The data collected from this study is research analysis shows that fast and normal time network lines A, B, C, D, F, I, J, K, L, activities include making water channels, digging foundations, installing foundations, ironing, laying hebel bricks, polishing, installing floor tiles, checking, overall finishing. So, the project scheduling time based on the CPM method is 124 days normal time and 91 days fast time to complete the project. Keywords: Critical Path Method, Project Development, Project Management, Scheduling.

Abstract

This research focuses on analyzing the implementation “of Total Productive Maintenance (TPM)” at PT. VPRK “by” utilizing “Overall Equipment Effectiveness (OEE) as an indicator” to assess “the” performance of grinding machines at PT. VPRK. The aim of the research is to evaluate the effectiveness and efficiency of the machine by identifying inhibiting factors that influence the performance of the grinding machine. The TPM method is applied to increase availability, quality and overall machine performance. OEE is used as a critical measuring tool to assess productivity and operational efficiency. The research results show that the OEE value of grinding machines in the January 2023 period is 79.78%. This value is not in accordance with the world-class OEE value standard, which is 85%. The biggest factor that influences the low OEE value is because the machine downtime is quite high, which affects the machine availability value so the machine availability value is 81.16%. Keywords: Maintenance, Overall Equipment Effectiveness, Total Productive Maintenance

Abstract

Queuing problems in everyday life can hinder the smooth running of activities in terms of time. With queues, the time to get service will be longer. If this problem is not resolved it will have an impact on users of the related services. XY gas station is one of the gas stations that is quite busy with two-wheeled users. The research method used in this case was direct observation at SPBU XY and interviews. The data in this research was obtained at SPBU carried out for 3 hours, namely from 09.00 WIB to 12.00 WIB. With the method used, namely maximin and minimax in game theory, to find out in terms of the advantages of Pertalite and Pertamax, the saddle point in the pay off matrix is ​​known, namely it lies in price and quality because the saddle point value obtained is the same, namely 27. So it can be said that this calculation is optimal. Because the value obtained is optimal and has a saddle point, the type of game theory used is pure strategy. Knowing that the customer strategy results are that Pertalite wins the price strategy, while Pertamax wins the quality strategy. Keywords: Game theory, Queuing, SPBU

Abstract

In the industrial era 4.0, most of the production processes use automatic machines. However, not a few companies still carry out their production processes manually, for this reason it is necessary to carry out an analysis of the value of effectiveness and efficiency between the workforce and also the machines so that production runs well 0020GHIn writing this data and information obtained through interviews, observation, and documentation. This research uses descriptive method using a quantitative approach. Effective capacity of labor 1515.2. Whereas the effective capacity of the extruder machine is 378.8, the labor factor has not yet shown the maximum figure because it has not reached 100%. This can be seen from the average efficiency which only reaches 25%, while the efficiency of using extruder machines is maximized with the results of calculating an average efficiency of 100% per month, suggestions that explain the efficiency of the use of labor and machines. The results of the author's research at PT. QRS revealed that the condition of the low level of efficiency in the labor factor needs to be reviewed regarding the operation of the extruder machine which is still manual for the input of production raw materials. The efficiency of using the extruder machine at PT.QRS is already very good, it's just a matter of maintaining it. Keywords: Effectiveness and efficiency, production factors, Polyester fiber.

Abstract

Increasingly fierce competition in the business world encourages companies to further develop ideas for effective and efficient ways to achieve predetermined goals. Many factors influence the success of achieving company goals. One of the most important forces that supports the achievement of company goals and increases company growth in the market is quality or quality score. Product or service quality control is critical to ensuring customer satisfaction and business success. One of the quality control tools is "Seven Tools" or Seven Quality Control Tools. The seven tools method is used for the production quality control process with the aim of solving various problems faced regarding the quality of a product. Types of defects found in cold room products at PT. There are 3 Pendawa Cipta Sakti, namely `: Glue doesn't stick, scratches on the coil, and holes in the styrofoam. Based on observations from graphs on histograms and Pareto diagrams, the most dominant type of defect is glue not sticking, therefore a cause and effect diagram for the type of defect glue not sticking is made.

Abstract

The competition in the Ultramilk milk market is becoming increasingly fierce due to strong competition from various competitors in the dairy processing industry, including brands like Cimory that are becoming more popular among consumers. This research aims to understand how brand switching occurs among Cimory and Ultramilk packaged milk consumers and to identify effective marketing strategies to retain customers. The methods used in processing the research data involve Markov Chain and Game Theory. The research was conducted by distributing questionnaires to Industrial Engineering students of the 2020 class at Singaperbangsa Karawang University. The results of the study indicate that the factors influencing brand switching are the size of the milk packaging. Marketing strategies that need to be improved for both milk products include pricing, flavor variations, packaging, and product availability. From the results of the Markov chain calculations on Ultramilk and Cimory milk, the researchers concluded that the market share forecast for the next 5 years shows an increase in Cimory milk sales by 18% and a decrease in Ultramilk sales by 4%, with variable chances of change each year. Keywords: Game Theory, Markov Chain, Marketing Strategy, Packaging Milk.
