Abstract

In Indonesia, the cattle agricultural business is one of the most significant food commodities for comply nutritional needs. The variable availability of cattle supplies is a challenge that the Padang City Agriculture Service must tackle. As a result, to establish the state of food security in Padang City, food security indicators must be calculated and analyzed. Food Security Quotient (FSQ) approach was used in this study to map the logistical network and beef food security. Following that, an information system based on a Geographic Information System (GIS) was created to represent the flow of the beef supply chain in Padang City. It was discovered from direct observations beef supply chain network in Padang City comprises of a fresh beef and a frozen beef supply chain. Beef suppliers from other regions, local breeders, feed lotters, slaughterhouses, wholesalers, retail traders, hotel / supermarket /restaurant/ catering consumers, rendang processing industry consumers (MSMEs), home consumers small-scale dining, and household consumers are all involved in the fresh beef supply chain. The analysis of the level of food security in Padang City revealed that three sub-districts were in the secure state, three were in a moderate state, and five were in a vulnerable state. The developed GIS is supposed to aid decision making in Padang City on food security predictions.

Abstract

Perancangan tata letak fasilitas merupakan salah satu faktor penting yang mempengaruhi kinerja dan kelangsungan proses produksi. Perancangan ini meliputi pengaturan mesin dan/atau pengaturan departemen/stasiun kerja dalam sebuah perusahaan. Perancangan yang baik dapat mengoptimalkan produktivitas serta meningkatkan kualitas produksi. Hal tersebut dapat dilihat salah satunya dari jarak minimum perpindahan material antar departemen. Jarak perpindahan material dapat ditentukan dengan metode konvensional, algoritma konstruksi, algoritma perbaikan dan algoritma hybrid. Metode konvensional meliputi metode SLP, metode konstruksi meliputi metode ALDEP dan metode algoritma hybrid meliputi metode BLOCPLAN. Belum adanya perancangan tata letak yang optimum di UMKM Tahu Ciracas, menyebabkan penumpukan, penghambatan proses produksi dan biaya material handling yang mahal, sehingga sebanyak sepuluh departemen akan dibuat perancangan tata letaknya. Pada tata letak awal memiliki total jarak perpindahan material antar departemen sebesar 242,6 m/hari setelah dilakukan penelitian diperoleh jarak perpindahan material yang baru dengan metode SLP sebesar 122.6 m/hari, metode ALDEP sebesar 150.4 m/hari dan metode BLOCPLAN sebesar105 m/hari. Metode BLOCPLAN dapat menghemat jarak perpindahan sebesar 57% sehingga menghemat biaya material handling

Abstract

Small companies that do not pay attention to product quality will experience marketing problems such as decreased product sales. Therefore, quality control is required for each product. Banana chips, for example, are considered very difficult to manufacture and often experience product defects. The cause of product failure is a weakness of a business today. The cause of this failure is unknown until now. Banana stick production based on data from August to September 2020 shows the number of defective products is approximately 28,875 kg of the total production, which is 323 kg. Therefore this research is intended to determine the factors that affect production defects in banana sticks. While the benefit of this research is to be able to control the factors that affect defects in banana sticks and can later increase profits and work productivity. The Six Sigma method is one of the tools commonly used in product quality control, where the concept of this method is to set quality standards of up to 3.4 rejects per million possibilities. Based on the results of banana chip defect data, it was found that the type of defect was sluggish with a percentage of 61% and the type of defect was burnt with a percentage of 39%. Factors that affect the two defects include human factors, materials, machines. The suggestion from this research is that of the three most influencing factors are humans, materials and machines. Companies need to plan improvements in stages so that in the future these products can achieve lean production.

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

CV. XYZ produces motor spare parts from various types of metal, spare parts that are often ordered by customers include bostep, underbone, flange and many more variations of motor spare part products that are produced. The data shows the effectiveness of the production of CV. XYZ in 2021 which is on average 100%, this proves that the achievement of production against the production plan cannot be achieved 100%. So there is often an imbalance in the production line. The purpose of this study was to determine the highest efficiency, lowest balance delay and optimal number of workstations from the production line resulting from the two methods, namely Ranged Position Wight (RPW) and Largest Candidate Rule. The type of research used in this research is comparative research. By comparing the percentage of efficiency, balance delay and number of workstations from the two methods, namely Ranged Position Wight (RPW) and Largest Candidate Rule. The data shows that the largest candidate rule method has an efficiency percentage of 107% for bostep, 85% for underbone and 94% for flange respectively. Then the smallest resulting balance delay is also generated from the production line design using the largest candidate rule method with 0.6 minutes each for bostep, 2.4 minutes for underbone and 4.3 minutes for flange. Besides that, the design of workstations using the largest candidate rule method, 2 workstations each for the bostep, 2 workstations for the underbone and 3 work stations for the flange..

Abstract

Inventory plays a pivotal role in a company's logistics, serving both to fulfill external customer demands and to enhance internal production efficiency. However, PT. XYZ in Medan did not address yet several cost factors that could significantly influence the overall procurement expenses of spare parts, particularly given that certain spare parts carry notably high purchase prices. While PT. XYZ has been placing orders for spare parts, these are typically initiated only when stock is depleted, based on the assumption that spare parts fall under the category of slow-moving goods. Consequently, it is imperative to conduct an inventory analysis to identify gap between the existing conditions and the outcomes derived from the proposed methodological approach. The methodology used in this study is Always, Better, Control (ABC) method to classify spare parts based on their cost percentage and Economic Order Quantity (EOQ) method to analyze the economic order size, order frequency and optimal ordering time. From the results of data processing that has been done, there are 7 types of spare parts that fall into category A and there is a decrease in Total Variable Cost (TVC) ranging from 13% to 40% from existing conditions. Ordering costs consist of telecommunications costs, labor costs, fuel costs and loading/unloading costs; while storage costs consist of electricity costs and maintenance costs. Scheduling the time of reordering or sending purchase order (PO) to the vendor, the number of spare part units to be ordered and the estimated arrival of spare parts are carried out based on the EOQ calculation that has been compared and adjusted to the previous existing conditions.
