Abstract

MSMEs in the manufacturing sector often face challenges in the efficiency of the production process, especially when implementing a make-to-order system that leads to high product variety and long lead times. This research aims to design improvements in the production process at PT. X, a furniture MSME in Bandung, by applying the Value Stream Mapping (VSM) and Business Process Re-engineering (BPR) methods. VSM is used to map initial conditions and identify non-value-added activities (waste), while BPR is used to formulate radical remedial solutions. The results of the analysis showed several main problems, namely delays in the supply of raw materials, the absence of standardization of sofa frames and covers, and production processes that ran in parallel. The proposed solutions include the implementation of make-to-stock and make-to-order hybrid systems, the implementation of safety stock of frame materials, and the standardization of dimensions and processes. These changes result in more efficient production processes, shorten order fulfillment times, and improve product quality consistency. This research shows that the integration of VSM and BPR can be a strategic approach in improving the manufacturing performance of MSMEs.

Abstract

Strengthening Village-Owned Enterprises (BUMDes) is crucial for reducing economic disparities in rural areas and promoting sustainable community development. While previous studies have primarily focused on financial structures and regulatory frameworks, this research adopts a participatory approach that actively engages local stakeholders in capacity-building efforts. Using BUMDes Mekarsari in Garut Regency as a case study, the study examines how participatory strengthening programs enhance the socio-economic resilience of rural communities. Employing qualitative methods—including in-depth interviews and field observations—it identifies key factors influencing BUMDes effectiveness, such as continuous training, institutional collaboration, and improved access to finance. The findings reveal that a participatory model not only fosters community engagement but also improves business sustainability and expands economic opportunities. In particular, the involvement of women and local artisans demonstrates the program’s inclusivity and potential for social transformation. Moreover, the integration of digital marketing strategies has opened new market access, further supporting rural entrepreneurship. To maximize practical impact, the study offers concrete policy recommendations, including strengthening institutional support for BUMDes, fostering multi-sector partnerships, and enhancing financial accessibility through local and national policies. These insights contribute to a more inclusive framework for rural economic empowerment, providing policymakers with a strategic foundation for designing community-driven BUMDes programs that ensure their long-term success as catalysts for local development.

Abstract

Aneka Jaya Store is a company in the furniture industry. It currently lacks a structured inventory system to manage demand, leading to intuitive and variable mattress ordering. This practice and limited warehouse space result in excess inventory and operational challenges. Consequently, the company seeks an enhanced inventory system to precisely define ordering intervals and quantities, aiming to minimize overall inventory costs. The proposed inventory management approach utilizes the T-method, the fixed order interval method, with a warehouse capacity constraint of 51 m3 for five designated products. This method mitigates stockouts by establishing order intervals (T) and maximum inventory quantities (M). Orders are placed based on the variance between the maximum inventory level and the remaining stock at the time of order placement. The T-Method employs both individual and joint ordering systems.The analysis reveals optimal order intervals and quantities after applying the individual and joint order T methods. For Export brands, joint orders are recommended every 17 days, with optimal amounts of 41 units for Export 120 and 40 units for Export 140. Teratai brand orders are bifurcated: individual orders for Teratai 90 products are suggested every 28 days with a supply of 26 units, while joint orders for Teratai 115 and Teratai 140 products are advised every 26 days, supplying 30 units and 27 units, respectively. Consequently, the total inventory cost for the five products amounts to IDR 15,992,603.49.

Abstract

The trend of digital-based transactions continues to increase along with the implementation of social restrictions during the pandemic, even it becomes a new habit for the millennial generation after the pandemic ends. In Southeast Asia, Indonesia was the first rank for the retail sales through e-commerce in 2021. The competition among e-commerce, especially the marketplaces in Indonesia has become very tight. Customer satisfaction, trust and loyalty are the important indicators for improving marketplace performance.  In this research, there are three main factors that are further investigated for their influence on customer satisfaction, trust, and loyalty namely e-service quality, e-word of mouth along with promotion and ads. The research was conducted on 162 Tokopedia user with the majority of the millennial generation. Hypothesis testing was carried out using the partial least square structural equation (PLS-SEM) technique. The results of this study indicate that e-service quality has a significant effect on loyalty through satisfaction and trust, promotion and ads has a significant effect on loyalty through satisfaction, and e-word of mouth has no significant effect on satisfaction, trust and consumer loyalty. To get consumer loyalty, the marketplace can improve e-service quality which has the most significant effect followed by promotion and ads.

Abstract

This study discusses the urgency of improving operational efficiency and service quality in the creative industry by addressing theoretical gaps in the application of Lean Six Sigma (LSS) and SERVQUAL methodologies. XYZ Creative Agency, a provider of social media management services, was selected as a case study to emphasize the practical contributions of the research. The main challenges include service delivery delays and insufficient service assurance. The Lean Six Sigma and SERVQUAL methods were applied to analyze and resolve these issues. The SERVQUAL analysis results revealed positive gaps in the assurance dimension (+0.0615) and the reliability dimension (+0.0154), indicating the need to enhance information clarity, client trust, and service timeliness. Value Stream Mapping (VSM) identified that delays primarily occurred during the content approval stage, while Fishbone Diagram analysis uncovered root causes such as inadequate team coordination, ineffective communication, and underutilized technology. Implemented solutions included the use of a digital project management platform to improve process transparency and efficiency, regular employee training to enhance competencies, and the development of a client feedback system. The DMAIC approach employed in Lean Six Sigma proved effective in designing data-driven solutions to improve operational efficiency and service quality. The implementation of these solutions is expected to reduce delays, enhance client satisfaction, and strengthen XYZ’s competitiveness in the creative industry.

Abstract

One-door container type of vehicle is the main tool for urban logistics in Indonesia which may take the form of truck, car, or motorcycle container. The operations would be more effective when it is performed through pickup-delivery or forward-reverse at a time. However, there is difficulty to optimize the operation of routing and container loading processes in such a system. This article is proposing an improvement for algorithm for sequential routing- loading process which had been tested in the small datasets but not yet tested in the case of big data set and vehicle routing problem with time windows. The improvement algorithm is tested in big data set with the input of the vehicle routing problem with time windows (VRP-TW) using the solution optimization of the Simulated Annealing process with restart point procedure (SA-R) for the routing optimization and Genetic Algorithm (GA) to optimize the container loading algorithm. The large data sets are hypothetical generated data for 800-2500 single-sized products, 4 types of container capacity, and 100-400 consumer spots. As result, the performance of the proposed algorithm in terms of cost is influenced by the number of spots to be visited by the vehicle and the vehicle capacity. Limitations and further analysis are also described in this article.
