Abstract

PT ABC Logistics is a company engaged in logistics services, especially providing truck and container services for land transportation. This company operates various types of trucks, including 20 feet, 40 feet, 21 feet, CDD, CDE, Fuso, and Tronton trucks. In carrying out its operations, as a logistics company, it must plan fleet needs accurately to fulfill each order. However, problems are still found in the form of fleet delays when heading to the stuffing location to the customer. To overcome this problem, the Root Cause Analysis (RCA) method is used to identify the root of the problem and reduce potential delays. The approaches applied include the use of Pareto Diagrams, Fishbone Diagrams, Failure Mode and Effect Analysis (FMEA), and proposing improvements using the 5W + 1H method. The results of the analysis show two main factors causing delays, namely fleet wait and container shortage. Priority improvements for fleet wait include optimizing route plans that have not been updated, incompatibility between delivery times and slot times, and lack of communication between the company and vendors. Meanwhile, to overcome delays due to container shortages, the focus of improvements is focused on improving communication systems, repairing damaged containers (such as leaks or holes), and optimizing communication between vendors and companies.

Abstract

Transportation has an important role in the logistics of a company, both in services and products. Increased orders in 2020 for wooden speaker products at CV. XYZ (Wonoayu-Sidoarjo) makes this company try to minimize transportation costs at their operational level. This study focuses on determining the relationship between changes in the type of fleet vehicle and the depot location on the operational costs of product delivery and the time to return to the depot in terms of adding trips. The methodology used in this study is the CVRP Multi Trip with Heterogeneous fleet vehicle and the Gravity Location Model based on the heuristic method. Saving heuristic method and nearest neighbor are heuristic methods used in computational studies to determine the order of visits to the formed sub-routes. There are 4 scenarios that are modeled to further analyze the results of these computations, namely: (1) CVRP multi-trip of old location with wings box truck, (2) CVRP multi-trip of old location with Fuso truck, (3) CVRP multi-trip of the new location with wings box truck, and (4) CVRP multi-trip of the new location with fuso truck. The results of the study concluded that there is a relationship between: (1) changes in fleet vehicle type with total traveling distance, (2) changes in depot location with total traveling distance, (3) fuel consumption rate on vehicle operating costs, (4) average vehicle speed on the time back to the depot. Scenario 4 is the best scenario in terms of traveling distance, fuel costs and delivery time. However, moving the depot center is not easy, so the scenario 2 is the most applicable condition considering that the fuso truck is available and has a higher utility than the wings box truck

Abstract

SMA Yadika 5 has one of the goals, namely "Providing knowledge and skills in the field of entrepreneurship and plant cultivation that are beneficial for students and the surrounding environment". In cultivating plants, supporting materials such as organic fertilizer are needed. Coconut juice is often used as a cooking ingredient in household activities, where the pulp from coconut juice that is no longer used can generally be reprocessed into organic fertilizer. Organic fertilizer can improve the chemical, physical and biological fertility of the soil, in addition to being a source of nutrients for plants. Organic fertilizer made from coconut pulp waste for plants can be one way to carry out the goals of SMA Yadika 5. In addition, it can be a solution for agriculture or plantations for housewives or family members of SMA Yadika 5 students in urban areas. Based on the analysis of the situation around us, it turns out that teenagers are interested in learning this knowledge but have not had the opportunity because there has been no training and counseling in managing waste. The target of this training in managing household organic waste from coconut pulp is male and female teenagers at SMA Yadika 5, Kembangan District, West Jakarta.

Abstract

PT ABC is a company in the manufacturing industry that produces premium spoons. The raw material used is 304 stainless steel. The high volume of defective production impacts reducing the level of customer satisfaction so that it indirectly causes losses to the company. The maximum defect rate determined and allowed by the company is 4.25% of total production. This study aims to determine critical defects and provide alternative improvements to reduce the level of product defects and increase the sigma level in making premium spoons. In this study, the Six Sigma method is used to determine the sigma level to be used as a reference in making corrective actions; the existing condition shows that the sigma level is 4.29, indicating that corrective steps need to be taken. The results showed that by analyzing Pareto diagrams, three critical defects occurred in spoon products: warping 98 pieces, freckles 102 pieces, and Discoloration 99 pieces. The root Cause Analysis method is used to identify factors that cause defects in spoons. The FMEA method is used to provide alternative improvements by reducing the potential for failure by considering the RPN value, where the RPN value of warping defects is 60, the RPN value of freckles defects is 60, and the highest RPN value obtained by Discoloration defects is 64. At the improvement stage, alternative improvements are given; from the proposed improvements, a decrease in the number of defects is obtained, which for warping defects is 15.5%, freckles are 16%, and Discoloration is 12.8% with a total decrease in the number of defects is 44.3%. From the results of the improvements that have been implemented, the DPMO value is 7,800 with a sigma level of 4.74. PT ABC adalah sebuah perusahaan dibidang industri manufaktur yang memproduksi sendok premium.
