Abstract

Project management is an effort to organize a project plan by taking into account the time and availability of resources. One of the projects used as the source of this research is the road rehabilitation project in Sumedang district. Roads are infrastructure supporting access to transportation and as a determinant of progress and economic development of a region. Sumedang City is a developing city and requires better quality and quantity of transportation. Many alternative roads are damaged and require road widening, one of which is Parigi Lama road. To improve and widen roads, the local village government undertakes a road rehabilitation project. This project is planned to be completed within 60 days. The road rehabilitation project is expected to run smoothly and be completed faster than the estimated time that has been planned. In this study the author uses the critical path method (CPM) to get the optimal time. From the results of calculations using the critical path method (CPM) this Parigi Lama road rehabilitation project can be completed within 42 days

Abstract

To control product quality, companies usually limit the defect rate. If the defect exceeds the predetermined limit, then efforts are needed to improve the quality of the product. The purpose of this research is to suggest the quality improvement for one of the vehicle spare-part products in a company located in Karawang industrial area, namely Piston Cup Forging. The product has a defect rate exceeding the predetermined target. Improvement steps taken are to determine the types and factor of defects using fishbone diagram (FBD), analyze the dominant causal factors of defects using failure mode and effect analysis (FMEA), and provide proposed improvements using the 5W+1H method. Based on the results of FBD analysis, it is known that the type of gaikei minus defect is caused by four factors, namely machine, man, materials, and methods. Furthermore, based on the FMEA results, this type of the defect occurs because it is caused mostly by human factors. Therefore, in the study, it is proposed that the operator needs to re-check the machine before it is operated and evaluate the operator periodically.

Abstract

Consumer satisfaction with a product could be determined based on several factors including quality, price, and fast distribution. Distribution activity is one of the important activities because it guarantees that products are circulated properly, do not accumulate in warehouses, and delivered on time. For micro, small and medium enterprises (MSMEs), distribution arrangements could provide significant savings in distance and distribution costs so as to increase profits. Besides that, distribution arrangements could also guarantee that products are delivered on time to consumers. This resarch uses a simple distribution determination method, the Savings Matrix method, followed by the Nearest Insert, Nearest Neighbour, and Farthest Insert heuristic algorithms. The purpose of this research is to help MSMEs that have the main distribution process to be able to arrange their distribution routes so that deliveries could be made on time and at minimal cost. In this research, a numerical example was used of a plastic equipment MSME which had problems with late delivery and the occurrence of round trips so that it became inefficient. In addition to determining the distribution route, four scenarios are also given for MSME to consider thus the distance and cost savings obtained are more significant. From the results of the calculation of determining the distribution route, it is found that the Savings Matrix method and the Nearest Neighbour heuristic method provide savings of around 12,82% or IDR 698,550 per month.

Abstract

PT XYZ is a company engaged in the automotive component industry for Wheel Rims or rims for two-wheeled and four-wheeled vehicles for the domestic and export OEM markets. The Wheel Rim which was produced by PT XYZ in one month found 255 units of defective products. The types of damage are broken, slips, markings, and inappropriate sizes. So research is needed with a focus on quality control of the products produced. This study uses the Statistical Quality Control (SQC) method to analyze the level of wheel rim product defects and the factors that cause product damage so that the company can find solutions to overcome the damage that occurs and improve the quality of the products produced. The categories of defects with the highest number were broken defects (52%), followed by inappropriate sizes (31%), no markings (6%), inverted marks (5%), pinched (4%), and slips (2%). The results of the study show that the focus of the problem for the company is the number of broken defective products and inappropriate product sizes. The human factor is the main factor affecting the number of defective products, where the lack of accuracy and haste makes the production process not go well.

Abstract

This research was conducted at PT Victorindo Kimiatama, a company that distributes paint and coating products in the Jabodetabek area and its surroundings where this company does not yet have a permanent distribution cost optimization calculation technique that can result in increased distribution costs. This study aims to determine efficient distribution channels and minimize distribution costs. The distribution cost calculation applies the transportation model by comparing the VAM and least cost methods. The calculation results show that there is a difference in the total cost of distribution where the VAM method produces a cost of Rp. 795,161.21 while the least cost method is Rp. 735,824.48, so that by using the least cost method the company can save distribution costs of Rp. 747,300.52 or 0.49% of the previous distribution fee

Abstract

The calculation of constraints at the Gorontalo 2x25 MW Orchid PLTU plant obtained a LOLP value of 37.84 days per year. This value is still above the reliability value of PLN standards. This is because in Unit 2, there were POs (Planned Outages) and MOs (Maintenance Outages) in June-July 2021, which were in the form of a first-year inspection in July. The FOR (Force Outage Rate) value is calculated based on disturbance data from plants in 2021. So a scenario was carried out for reliability improvements in the plant. From scenario 1, a reliability value of 36.86 was obtained, and scenario 2 obtained 16.16 days per year; scenario 3 had a value of 1.54 days per year.

Abstract

Inventory is synonymous with warehouse, and storage grouping has an essential role in warehouse management to facilitate activities on products that occur in the warehouse before being sent to customers in the future. The problem with the XYZ packaging warehouse is that the different conditions of goods turnover cause storage in the packaging warehouse to become irregular. This study aims to classify inventory so that it is allocated better based on the speed of movement of goods. Quantitative data was obtained through observation, literature study, and company historical data. The method used is FSN Analysis, a classification based on an item consumption level into three categories. The results of data processing that show from this study were 17 items in the fast-moving category with a turnover ratio greater than 3 (TOR > 3), 14 items in the slow-moving category with a turnover ratio between three or less than three and one or more than one (3 ≤ TOR ≤ 1), and 2 items in the non-moving category with a turn over ratio of less than 1 (TOR < 1). FSN Analysis can improve warehouse management in controlling the storage of these goods in groups.

Abstract

XYZ Company is the largest manufacturing company in Indonesia that produces various materials such as instant cement, lightweight bricks (AAC), wall panels, and floor panels. However, the company faces challenges in the supply of raw materials, which hinder the production process and lead to product shortages. The most frequent shortages occur in the 210 instant cement product, with a shortage rate of 99.3% over a six-month period from October 2022 to March 2023. This study employs the Material Requirement Planning (MRP) method to address this issue. The objective is to plan the scheduling of raw material orders and project future requirements. Data on demand, inventory, raw material structures, and supporting data are used in the calculations. As a result, the scheduling of raw material orders for the 210 instant cement product is conducted for three consecutive months, namely April, May, and June 2023. Each month, raw materials such as silica sand, lime, cement, and additives are meticulously planned with several orders based on the lead time of each material.
