Abstract

One of the manufacturing companies engaged in agribusiness, one of which is processing cooking oil, often occurs damage to goods due to excess stock of goods and increases expenses for storage costs. Before carrying out the production process, the company must forecast demand to find out how much the estimated raw material needs will be used as inventory control so that there is no excess or shortage of stock that will harm the company. The purpose of this study is to predict the amount of cooking oil demand in the next 12 periods, plan the lot size of raw materials with the lowest cost and determine the right time to order raw material supplies. The method used in forecasting is Autoregressive Integrated Moving Average (ARIMA) and lot size planning with Materials Requirements Planning (MRP) FOQ and POQ techniques. ARIMA forecasting results with a MAPE value of 33% and the lowest cost technique chosen by POQ

Abstract

Domestic CBU flows at Car Terminal of Tanjung Priok Port are increasing. This resulting in a decrease of utilization in the open field at domestic car terminals. This can lead to excessive cost increases and also cause congestion in the Tanjung Priok Port area. Therefore, the Car Terminal at Patimban Port was built with the aim of reducing logistics costs caused by congestion at Tanjung Priok Port. This study aims to describe the competitiveness based on logistics performance and the right marketing strategy to be applied at the Domestic Car Terminal of Patimban Port in 2021.The research method used is descriptive qualitative with an approach using Resource Based View (RBV) analysis, Politic, Economics, Social, Technology, Legal,and Environment Analysis PESTLE analysis and Five Forces Porter Model Analysis. Furthermore, to determine the strengths, weaknesses, opportunities and threats of the Domestic Car Terminal at Patimban Port SWOT analysis and also 7 P's Marketing Mix was used to determine the right marketing strategy. The results of this study reveal that The Domestic Car Terminal of Patimban Port doesn’t have competitiveness yet according to Porter Competitiveness indicator. Therefore, marketing strategy has been identified and developed for the sustainable of Domestik Car Terminal business in Patimban Port. In terms of logistics performance, the Domestic Car Terminal facility is one of the strength factors for the Domestic Car Terminal of Patimban Port.

Abstract

Line Balancing is an assignment of a number of jobs into interconnected work stations in one line or assembly line with the aim of minimizing idle time on the hydraulic excavator assembly line, the assembly line specification has 27 work stations with 150 work elements. In the process of assembling the hydraulic excavator, there was an overtime that exceeded the takt time at work station 18 (BF 04), which resulted in the failure to achieve the production target of 5 units/day. One way to overcome this problem is to apply the line balancing method on the hydraulic excavator assembly line, the approach used is the Regional Approach, Ranked Positional Weight, and Largest Candidate Rules. Based on the analysis that has been done, it can be concluded that the Ranked Positional Weight approach has the best value with the number of work stations 18, line efficiency of 95.70%, balance delay of 4.30% and idle time of 66.84 minutes and also has good results. better than the initial conditions before the line balancing method was applied.

Abstract

The research at hand addresses a consequential concern related to PT XYZ's procurement procedure, specially their process to order raw materials for the production process in excessive quantities. This practice of them lead to the accretion of raw materials with in the company's warehouse due to limited storage capacity. The focal point of this study is to determine the optimal quantity of ordering raw materials and to indicate the suitable warehouse size that will result in the most cost effective total inventory management. To accomplish this objective, the research adopts well-establishes process EOQ (Economic Order Quantity) model with ll development. Moreover the study considers the significant of warehouse capacity by implementing the Lagrange Multiplier Method. Eventually consequences of the research display that the optimal order quantities for raw material A and B are 55.2 tons and 36.8 tons respectively. Additionally the study indicate that the optimal total inventory cost for raw materials A and B, representing to Rp21,362,417 and Rp17,533,999, respectively.

Abstract

PT. X is a company engaged in logistics, especially as a third party that provides services in the form of warehouse rental. As well as storage warehouses that are used to accommodate new goods from vendors to overcome all logistics in shipping goods. Based on the analysis carried out directly at the warehouse location, it was found that there was a problem regarding the accumulation of goods that came in the staging area , due to the location of forklift storage that was far from the location in the warehouse to the proposal to minimize material handling costs. With these problems, an analysis of the layout proposal based on data was carried out using the System Layout Planning (SLP) method, the result of the proposal was aimed at minimizing the costs incurred by the company and reducing the distance in the material handling flow. In this case, the calculation using System Layout Planning (SLP) obtained the results of changes regarding material handling costs, the change was initially Rp. 2,612,245 and the proposed material handling cost saved Rp. 559,251 to Rp.2,052. 994 and for the distance obtained the result After the implementation of the proposed layout, the material displacement flow distance / week was 23065m from the initial layout of 25326m and there was a difference of 2,261m. With the implementation of these changes, researchers hope that companies can achieve better operational efficiency and optimize the use of existing resources.

Abstract

PT. Blue Gas Indonesia is a company engaged in sales, distribution, gas refiling and assembling. This company also has a household equipment production and assembly business unit under the Vienta trademark and markets Blue Gas and Vienta kitchen equipment products such as Hand Stand Mixers. This company has a problem, namely PT. Blue Gas Indonesia still uses a manual system to plan Raw materials for making handstand mixers. This can cause problems, such as frequent calculation errors when Raw material stock is too small, resulting in the production process being hampered. Therefore, this research aims to find out the optimal quantity of Raw material needed and to know when to place a new order using the MRP Method, Lot For Lot-for-lot technique, Economic Order Quantity, and Period Order Quantity. The results of the research produced From the results of analysis using the Material Requirement Planning method by calculating Lot Sizing using three techniques, namely Lot For Lot, Economic Order Quantity, and Periodic Order Quantity on Raw materials for Hand Stand Mixer products, it can be concluded that the lotting or lot-sizing technique costs money. The minimum inventory for almost all Raw materials is the Lot For Lot technique with a total inventory cost of IDR 4.422.348.978,59.
