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

The benchmark for the success of a business or product is to measure the satisfaction of customers who have used or felt the goods or services. The customer's expectations of the function and emotional happiness factors that arise from the use of goods or services are entirely the responsibility of the producer. So that manufacturers need to focus on what attributes must be presented in a product or service to increase customer satisfaction. The decrease in customer interest in providing vehicle service at an automotive company in Sidoarjo is the problem studied in this study, to analyze the level of customer satisfaction and attributes that are priority improvements as recommendations for the company. Data generated from customers is processed and analyzed using the Service Performance (SERVPERF) and Lean Service methods. Based on the results of data processing, it can be concluded that the level of customer satisfaction with service quality is 82.3%, and three service attributes are classified as a top priority and two types of critical waste.

Abstract

Accidents and injuries are still 20% more common in small companies, including MSMEs, compared to large companies. Lack of safety awareness is one of the obstacles why safety is not widely implemented in the MSME area. In line with this description, the MSME group in Wiyung District, Surabaya City, has not experienced an increase in profit over the past few years, due to declining employee productivity. This is suspected because of the frequent occurrence of accidents that cause injuries to employees, thereby affecting their absenteeism levels and impacting lost working days which affects productivity. Based on these problems, training was carried out to increase safety awareness through the Work Improvements in Small Enterprise (WISE) program which aims to increase safety awareness for MSME groups as well as improve working conditions through the application of safety values.

Abstract

PT. PQRS is an agro-industrial company that plays a role in processing fresh tea leaves into various ready-to-consume tea products. Because there is no definite time standard for the production process, the corporation cannot accurately estimate the number of workers needed based on the workload at each work station, especially the packaging station. It is hoped that by combining the work sample approach with conventional time measurement methods, the author will assist businesses in identifying the ideal number of workers. The average time for packaging tea during 60 observations was 219.94 seconds, and the average working time was 480 minutes or 28,800 seconds or 8 hours a day, according to calculations that had been carried out. The number of workers in the tea packaging section is based on labor requirements calculated using a work sampling approach. According to the calculation of labor requirements using the work sampling method, the number of employees in the tea packaging section, which previously required 21 employees, has now become 18 employees at the PT.PQRS tea packaging station

Abstract

Inventory is crucial and very important in every production series. So good inventory management is needed to increase the optimization of production activities. Decision making in order to reduce risks in the warehouse if procurement of too many goods in a short period results in increased storage costs. This research proposes inventory management using the Economic Order Quantity method with the results for grinding blades, bolts and acetylene respectively being EOQ of 136.7; 154.9; and 42.42.
