Abstract

Driven by increasing internet usage, Indonesia is experiencing a significant rise in e-commerce activities, with transactions projected to grow from 66 million to 99 million by 2029. This growth necessitates a hybrid approach combining online and offline sales channels to maximize market coverage. However, this dual-channel strategy poses challenges in pricing, as customer preferences heavily influence purchasing decisions. This study analyzes pricing strategies within a dual-channel supply chain (DCSC). It examines two main scenarios, centralized and decentralized systems, to determine optimal pricing strategies considering in-sales service and discount. The decentralized system employs a Stackelberg game model, where the manufacturer sets prices first, followed by the retailer. A clothing company is used as a practical case study to apply these mathematical formulations. The study highlights how parameter variations such as customer preferences, service, and unit costs influence price. Notably, the decentralized system often results in higher profitability than the centralized approach under specific conditions. Sensitivity analysis further reveals that while some parameters remain stable, customer preferences significantly affect pricing decisions. A preference for online shopping tends to favor a centralized strategy, indicating that coordinated pricing can mitigate channel cannibalization risks. The study underscores the complex interplay between pricing strategies, discounts, and in-sales services in dual-channel supply chains

Abstract

A truck dealership company, specializing in maintenance, repair, and spare parts sales, faces stockout challenges that hinder its ability to meet demand for moving code 1 spare parts. The absence of effective forecasting methods and safety stock policies exacerbates these issues. This study aims to optimize inventory management by identifying suitable forecasting methods and implementing the Continuous Review System (CRS) to establish safety stock and reorder points as the parameter for procurement planning. The results indicate that the Double Exponential Smoothing (DES) method effectively predicts demand, while the Monte Carlo simulation method performs better for spare part 493051110L. The CRS approach improves the fill rate and reduces stockout risks, ensuring better inventory management for the company. These findings provide a framework for the company to enhance its spare parts inventory strategy, contributing to improved service reliability and operational efficiency.

Abstract

The swift advancement of 3D printing technology has emerged as a significant innovation applicable across multiple domains. 3D printing is the method of fabricating three-dimensional items from digital models by incrementally layering materials. The integration of 3D printing in educational institutions can facilitate a more engaging and innovative learning environment for students. Implementing 3D printing can enhance students' creativity and critical thinking abilities, which are vital for navigating technological progress. The approach utilized in the 3D printing introductory curriculum entails showcasing the utility and possibilities inherent in 3D printing technology. This procedure proceeds by incorporating Computer Aided Design (CAD) software and detailing the conversion of CAD drawings for compatibility with a 3D printer. An overview of the components of a 3D printer is provided to assist educational institutions in utilizing and maintaining the device. In this program, educators exhibited considerable enthusiasm for mastering the usage of 3D printers, which will subsequently facilitate the execution of teaching and learning activities in the school environment. This program can be further enhanced by incorporating a comprehensive introduction to several types of 3D printers, thereby augmenting initiatives to elevate the quality of education at SMA Negeri 9 Yogyakarta.
