Abstract

One of the problems with the Vehicle Routing Problem (VRP) is the problem of fulfilling customer requests according to the location that must be supplied from depots that have limited vehicle capacity. This also happened to Distributor PT. XYZ is located in Lamongan. Every day the distributor of PT. XYZ distributes fertilizer to several cities in East Java, one of which is in the city of Blitar. The problem that happened to the distributor of PT. XYZ does not yet have an optimal distribution route, resulting in delays in the delivery process. Optimization of distribution routes can be done by finding the shortest route in fertilizer distribution in the Blitar area. With the saving matrix and nearest neighbor method, the best route arrangement can shorten the distance and product delivery time. The final result will be savings in distribution costs because it can reduce fuel consumption for fertilizer trucks, reducing the company's variable costs and reducing environmental emissions.

Abstract

VRP is concerned with determining routes for problems involving more than one vehicle with a certain capacity to serve consumers with their respective requests. Route determination is one of the important factors in delivering products to consumers. Determining the optimal distribution route can minimize distance, shorten product delivery time and save transportation costs. PT. XYZ is a company engaged in the distribution of consumer goods. Problems that are happening at PT. XYZ is a product distribution problem where the number of vehicles is limited. The number of customers and the distance from the depot to the customer and from one customer to another is far away. Therefore, it is necessary to determine distribution routes, especially in transportation problems, to save time, distance, and distribution costs. The objectives to be achieved from research at PT. XYZ is to determine the product distribution route using the Sequential Insertion method. Based on the data processing results, the route Sequential Insertion method can serve customers in 5 routes with a total distance of 227.8 km, a total travel time of 15.9 hours, and a total distribution cost of IDR 145,792/week. The travel distance savings are 28.20 km, and the percentage of distribution cost savings is 11%, or the distribution cost savings are IDR 866,304/year. So, the Sequential Insertion method can be applied to determine the optimal distribution route to produce a minimum distribution cost

Abstract

Every company needs to optimize and improve its performance. Performance improvement strategies cannot be well formulated if there has never been a performance measurement itself before. Determining the overall condition of the company can be done by assessing the performance of the entire lines of the supply chain. The SCOR model is considered appropriate for complex supply chain activities because it has a measurement process of plan, source, make, deliver, and return. The scale for each process in the supply chain is different, so the Snorm De Boer normalization technique is applied to equalize the assessment units for each criterion. Based on the performance indicator (PI) calculation, six PIs scores are below the average performance. Those six Pis are raw material planning, production planning, planning cycle time, yield, product defect from production, and the number of equipment maintenance. The six PIs are assessment indicators for the planning process and production process, so an improvement of the management system for both activities is essential to be carried out immediately to improve overall supply chain performance.

Abstract

Micro, Small and Medium Enterprises (MSMEs) experience difficulties in managing Occupational Safety and Health (OHS) in the workplace. Apart from poor OHS conditions, it is also caused by a lack of systematic OHS management. Work Improvement in Small Enterprises (WISE) is a participatory training program to help MSMEs increase workplace productivity and efficiency through implementing OHS aspects. The high number of accidents and injuries occurred 20% more often in small companies compared to companies with more than 100 workers and 40% more often than in companies with more than 1000 workers. So, it can be concluded that MSMEs are more vulnerable to work accidents and K3 management in MSMEs is still very lacking. This research aims to reduce the risk of work accidents in MSMEs using the WISE method.

Abstract

A bank can be considered good when it can satisfy its customers by providing excellent service and comfort. One of the banks facing challenges in this regard is PT. ABC Sidoarjo branch. This branch has only three teller services. In the queue, customers often feel uncomfortable, and bored, and their time is wasted waiting. This research aims to minimize waste to optimize the teller service queue. The research starts with data collection, distributing questionnaires, and analyzing data using Lean Service methodology. To visualize the value stream of business processes at PT. ABC, Value Stream Mapping (VSM) is used. Cash deposit activities contribute significantly to waste. Within the cash deposit service process, it was found that value-added activities account for 64%, necessary non-value-added activities for 29%, and non-value-added activities for 7%. The critical types of waste are waiting and unnecessary movement, each with a percentage of 24% and 22%, respectively. After the research and proposed improvements were implemented, After the improvement, the non-value-added activity decreased from the initial 900 seconds to 300 seconds, which represents a 66.7% reduction. As a result, customers no longer need to wait in line for an extended period.

Abstract

The aim of the research is to integrate the lean six sigma supply chain management concept to design and measure performance measurement models and determine the causes of company performance failures and then provide recommendations for improvement according to the lean concept. This research was carried out only up to the improvement stage. The result of this research is an overall performance measurement of 66.6666 where this value can be categorized as "Average". This value shows that supply chain management activities at PT. PG Candi Baru is running moderately and obtained 9 KPIs that have not reached the target. Waste is the cause of the 9 KPIs not achieving the target, namely waste defects, waiting, not utilizing employee knowledge, skills and abilities and extra processing. Recommendations for improvement given to the company to reduce the occurrence of waste are: For defects in sugar quality, the proposed improvement is to carry out milling in accordance with established standards and use raw materials that comply with specifications. When waiting for raw materials to be late, the proposed improvement is that the plant department must carry out earlier purchasing planning to avoid waste waiting and prioritize TS suppliers because they have a higher weight than other suppliers. The proposed improvement for the production department is training on how to forecast production scheduling. In extra processing, the proposed improvement is that the company can provide a quality control list when inspecting the finished product so that the inspection is more controlled.
