Abstract

Delta Presto SMEs is a SMEs that is engaged in the production of processed Bandeng fish. The products sold are fried bandeng fish, presto bandeng fish, bandeng fish brains, smoked bandeng fish. The problems experienced by SMEs are for presto bandeng fish products, the vacuum sealer owned by SMEs is old and often damaged, the suction power is low so the products can not last long, only about 7 to 9 days. The second problem is that the box used as packaging for fried bandeng fish is not laminated so that the oil seeps out of the box and the box packaging becomes oily on the top and bottom. To overcome these problems, a new vacuum sealer was procured and also a packaging design using a laminated box. The results of the new vacuum sealer can make the product last longer between 2 to 3 months because the suction power is stronger, besides that it also speeds up the production process because it can be used to vacuum two packs of pressure bandeng fish. The results of the laminated box design can improve the aesthetic appearance of the fried bandeng fish box

Abstract

UD. Podo Moro, a folding ironing board manufacturer in Surabaya, experienced recurring Out of Stock (OOS) conditions caused by fluctuating demand, long supplier lead times, and the absence of a structured raw material planning system. These conditions resulted in production delays, emergency purchasing activities, and increased operational costs. This study aims to optimize raw material planning and minimize inventory costs through the implementation of the Material Requirement Planning (MRP) method. Demand forecasting was conducted using three quantitative methods, namely Moving Average (MA), Weighted Moving Average (WMA), and Exponential Smoothing (ES). The selected forecasting results were then used to develop Aggregate Planning and a Master Production Schedule (MPS). Furthermore, MRP calculations were performed using three lot sizing techniques: Lot for Lot (LFL), Economic Order Quantity (EOQ), and Fixed Order Quantity (FOQ). The results indicate that the Moving Average (MA) method produced the most consistent forecasting accuracy based on Mean Absolute Deviation (MAD) values and tracking signal analysis. Among the evaluated lot sizing techniques, the EOQ method generated the lowest total inventory cost of Rp 346,275,216, compared to Rp 417,215,710 for LFL and Rp 488,289,859 for FOQ during the January–June 2026 planning period. The implementation of MRP proved capable of improving procurement scheduling, reducing inventory shortages, minimizing emergency purchasing activities, and enhancing operational efficiency. Therefore, the EOQ-based MRP approach is recommended as the most effective strategy for minimizing OOS costs at UD. Podo Moro.

Abstract

Surplus materials generated from textile production processes often remain underutilized due to the lack of integration between manufacturing and retail operations, resulting in idle inventory, unrecorded transactions, and lost sales opportunities. This study aims to improve sales performance and inventory utilization in textile SMEs through the implementation of Odoo ERP with intercompany and e-commerce integration. The study was conducted in a textile SME consisting of a production unit and a retail unit operating under separate business entities. The System Development Life Cycle (SDLC) using the waterfall model was employed to analyze requirements, design the system, configure Odoo modules, and perform functional testing and user acceptance evaluation. The proposed solution enables the automatic generation of intercompany transactions, including Sales Orders, Purchase Orders, and Vendor Bills, while synchronizing inventory, sales, and accounting information in real time. In addition, the e-commerce module provides a digital sales channel for surplus materials that were previously marketed through conventional methods. The results indicate that the integrated system improves transaction traceability, reduces manual data entry, and enhances inventory visibility across business units. Furthermore, the utilization rate of surplus materials increased from 17% prior to implementation to full absorption through the integrated digital channel during the evaluation period, eliminating idle inventory and creating additional economic value. These findings demonstrate that ERP-enabled intercompany integration can support operational efficiency and strengthen sales performance in textile SMEs
