PT XY, a company engaged in the<br>production of heavy equipment andmining industry components, has been relying on only<br>one brand of grinding stones, namely Nippon Resibon. This reliance has the potential to<br>cause supply limitations and sub-optimal costs. Therefore, this study aims to evaluate the<br>efficiency of several grinding stone brands in improving the company's productivity. The<br>method used is Data Envelopment Analysis (DEA)with an input-orientedVariable Return<br>to Scale (VRS) approach. The data analyzed includes cost, Ergonomic Aspect, stone<br>saving, productivity, and Total Inventory. We used EMS software to process the data and<br>identify the most resource-efficient brands. The results of the analysis show that there is<br>a variation in the level of efficiency among the tested grinding stone brands, with Kinik<br>grinding stone brand being selected as the most efficient grinding stone brand with a value<br>of 165,98% and Norton BDX grinding stone brand as the last grinding stone brand with<br>a value of 94.44%.</p> 2025-04-30T00:00:00+07:00 Copyright (c) https://journals.upi-yai.ac.id/index.php/TEKINFO/article/view/4710 Penentuan Safety Stock dan Reorder Point Pada Pallet Kosong Berdasarkan Peramalan ARIMA di PT XYZ 2025-05-04T09:31:46+07:00 Rio Nurdiansyah 2110312006@mahasiswa.upnvj.ac.id Alina Cynthia Dewi acd@upnvj.ac.id Tatik Juwariyah juwariyah_tj@upnvj.ac.id <p>PT XYZ faces stockout issues for empty pallets due to uncertainties in demand<br>planning. These stockouts occur as a result of production schedule shifts caused by<br>bottlenecks such as raw material delays and machine downtime, which hinder<br>production and distribution processes. This study aims to determine the safety stock<br>(SS) and reorder point (ROP) for empty pallets based on demand forecasting. The<br>Autoregressive Integrated Moving Average (ARIMA) method is employed to forecast<br>empty pallet requirements, with the forecasting results serving as the basis for<br>determining SS and ROP to optimize inventory levels. The findings indicate that the<br>ARIMA (0,1,1) model, with a Mean Absolute Percentage Error (MAPE) of 16.18%,<br>yields a safety stock (SS) of 59 pallets and a reorder point (ROP) of 2,201 pallets. By<br>adopting this approach, the company can enhance supply chain efficiency and ensure<br>smoother production and distribution operations.</p> 2025-04-30T00:00:00+07:00 Copyright (c) https://journals.upi-yai.ac.id/index.php/TEKINFO/article/view/4711 Integrasi Model Sarima dengan Optimasi Algoritma Genetika dalam Peramalan Penjualan Sepeda Motor di Indonesia 2025-05-04T09:31:46+07:00 Yohanes Anton Nugroho yohanesanton@uty.ac.id Hotma Antoni Hutahaean hotma.hutahean@atmajaya.ac.id <p>A variety of factors will influence the sales of a product, so it is necessary to analyze it to anticipate<br>changes in the business environment. This research explores how accuracy in forecasting can help<br>companies make policies and determine the right strategy. This research aims to test the<br>performance of the Seasonal Autoregressive Integrated Moving Average (SARIMA) and Genetic<br>Algorithm (GA) methods in forecasting motorcycle sales in Indonesia. The SARIMA model<br>forecasts seasonal patterns formed from sales data, while GA is implemented to optimize model<br>parameters to improve prediction accuracy. The data used in this research comes from motorcycle<br>sales reports in Indonesia from 2021 to 2024. Forecasting performance with the GA-SARIMA<br>model is tested and evaluated using the AIC, MAD, MSE, MAPE, and MAE parameters. The<br>performance of all parameters shows that the GA-SARIMA model has the lowest value, so it<br>performs better than the traditional SARIMA. The validation results using actual sales show that<br>the GA-SARIMA model shows an error in January 2025 of 2,698, while in February 2025, it is<br>71,924. Despite the error, the forecasting is still within the upper and lower limits, so the resulting<br>model can still forecast motorcycle sales in Indonesia.</p> 2025-04-30T00:00:00+07:00 Copyright (c) https://journals.upi-yai.ac.id/index.php/TEKINFO/article/view/4712 ANALISIS DAN PERANCANGAN TASK MANAGEMENT SYSTEM BERBASIS WEB (STUDI KASUS: PT.

The<br>problems faced by the company are late delivery, discrepancies in the quantity of goods, and the<br>quality of packaging materials that do not meet standards, which can disrupt the production process<br>and cause losses. This study aims to determine which criteria should be considered in selecting<br>suppliers. Through the analysis conducted, there are seven main criteria that are evaluated: quality<br>(0.352), cost saving (0.229), delivery (0.118), quantity (0.109), service &amp; complaint handling<br>(0.081), compliance (0.076), and environment (0.035). The evaluation results show that Supplier C<br>is the best choice with a total suitability value of 0.415, followed by Supplier B with a value of 0.359,<br>and Supplier A with a value of 0.226. The inconsistency value in this model is 0.03, which indicates<br>a high level of assessment consistency. The application of AHP in the selection of secondary<br>packaging material suppliers at PT Bio Farma (Persero) has various implications, including<br>increasing procurement effectiveness through objective criteria analysis and weighting. Focusing<br>on quality and timeliness will reduce the risk of delays. Transparent evaluation also strengthens the<br>company's relationship with suppliers, enabling the realization of better performance over time. The<br>selection of Supplier C based on AHP provides a strong basis for decision-making because of the<br>availability of logical quantification.
