Abstract

The construction of cafe and salon by PT DTD has been delayed in terms of time. The purpose of this study is to calculate the best time optimization and determine the critical path of the cafe and salon construction project at PT DTD. This research is an evaluation of a project that has been completed. The methods used are Critical Path Method (CPM) and Project Evaluation Review Technique (PERT). The software used is POM-QM for Windows. The project runs for 15 months or 62 weeks from the initial target of the contractor being 8 months. Using POM-QM, from the PERT method, the optimum time for the project is 50 weeks. Project optimization can be carried out using PERT and CPM methods with POM QM software.

Abstract

The research was conducted to analyze the calculation of demand forecasting and inventory of spare parts . The data collection method uses descriptive quantitative by conducting literature studies, interviews, and collecting sample data of 140 spare parts from June 2019 to June 2020. The data classification process with FSN method, obtained 13 fast moving spare parts use for calculating demand forecasting based on the Triple Exponential Smoothing method. The results from the trial error to get the smoothing value of alpha, beta and gamma errors prioritize to best MAPE <5%. Some MAPE errors above 5% are X000000 000254 MAPE = 5.68% , X000000 005566 MAPE = 21.12, X400 401 10 72 MAPE = 13.14, and X400 401 26 71 MAPE = 16.70. The calculation result of safety stock and reorder point find 4 spare parts have low level inventory have to reorder.

Abstract

This study focuses on inventory control of spare parts outside the prohibition 7.50-16 to streamline inventory costs. The method used is Economic Order Quantity with the type of case study design at the company PT. XYZ with the object of research is the supply of Outer Tire Parts 7.50-16. In data collection, the researcher compares the Traditional or Actual Company Method with the Economic Order Quantity Method in 2019 and 2020. The data that has been collected becomes several references in the calculation so that there is a difference between the two methods. The results show that the Economic Order Quantity method can streamline inventory control beyond 7.50-16 at PT. XYZ.

Abstract

This study aims to determine the most valid forecasting method based on the time series method. This research uses a quantitative descriptive method, the research variable is sales data of MT products belonging to PT. RSM period August 2018 to January 2021. Data processing using Microsoft excel and Minitab 19 software. ABC analysis results show product codes RSM020, RSM021, and RSM017 occupy the three highest ranks in class A by contributing 26.16% sales figures. Based on the forecasting results using various time series methods (linear trend, decomposition, moving average, single exponential smoothing, Holt Method, and Winter Method) it is found that the Winter Method produces the lowest MAPE value, which is below 20%. Product code RSM020 with an alpha value of 0.06; beta 0.09; and 0.07 gamma produces 17.2% MAPE. Product code RSM021 with an alpha value of 0.01; beta 0.01; and 0.01 gamma produces a 15.3% MAPE. Product code RSM017 with an alpha value of 0.01; beta 0.02; and 0.02 gamma produces 18.1% MAPE.

Abstract

Inventory management is one of the keys to the success of the production process in any company, including manufacturing companies. Therefore, determining the optimal amount of inventory is crucial for inventory management. In a production process, sometimes a condition is found where the amount of inventory far exceeds what is needed, so that in the process of implementing the specifications change of an inventory will take quite a long time, this is due to an effort to use up obsolete inventory first, so it is necessary to calculate the optimal value of the company inventory. In this research, using the Economic Order Quantity and Reorder Point analysis method in the POM-QM software, it is expected to determine the optimal value of the purchase amount, Safety Stock, Reorder Point, and the required inventory costs of J950010 nuts. The results showed that although there were differences between the results of the POM-QM calculation and the application in the field, the management of J950010 nut stock is optimal.
