Abstract

Cable cars as a means of transporting goods and passengers have been applied in several countries. Cable cars can reach areas with difficult terrain to reach so as to support logistic systems for rural areas that have hard-to-reach terrain. The southern district of Garut Regency has extensive agricultural and plantation land and terrain that is quite difficult to reach so that the installation of cable cars will be able to provide the community with ease in transporting agricultural products. The existence of a cable car that has been installed in Sutenjaya Village, Lembang will facilitate development because it can be used as a pilot project.Cable cars as a means of transporting goods and passengers have been applied in several countries.

Abstract

Warehouses play an important role in the supply chain by serving as a link between producers and end consumers. Warehouses not only serve as a place to store goods, but also have other important functions. Operational efficiency and logistics control in finished goods warehouses are increasingly becoming an urgent need for companies in various industries. However, ineffective warehouse management can lead to negative impacts such as decreased profits and customer dissatisfaction. Therefore, efforts are needed to manage warehouses with good efficiency and structure. This article discusses the concept of Warehouse Management System (WMS) and finished goods warehouse management in an effort to improve operational efficiency and logistics control. Through a qualitative approach with data acquisition using literature review from various relevant sources, the relationship between the use of WMS and increased productivity in a company is examined. The results showed that there was a significant improvement in the performance of a company. The WMS is proven to increase the number of orders received and the company’s operational efficiency. WMS aids inventory management with real-time stock data, preventing shortages or excesses. Successful implementation demands proper strategy, tech utilization, planning, system integration, and employee training. Thus, WMS implementation can bring about positive changes in warehouse operational efficiency, inventory optimization, and meeting customer needs.

Abstract

Inventory management is a crucial aspect for the smooth operation of businesses, as the availability of stock significantly impacts the company's operations. Supporting successful inventory management involves utilizing an information system that assists the company in monitoring inventory in real time and presenting accurate and up-to-date information. The purpose of conducting this research is to comprehend the concept of inventory control and its interrelation with an information system. The stage of this research is to carry out a research framework starting from planning, designing until the system can be used by users. In addition, the results of a literature review that was conducted using data from earlier studies by other researchers were used. The role of information systems in inventory control is of paramount importance, as it can enhance effectiveness and efficiency by providing real-time data about warehouse stock, thereby reducing the risk of errors that could result in losses for the company. Therefore, the development of an inventory control information system is anticipated to alleviate issues related to inventory management within the company.

Abstract

Operational efficiency and product quality are crucial for enhancing the competitiveness of MSMEs in the era of globalization and digital transformation. This study explores the application of Six Sigma to reduce product defects at MSME X, a footwear manufacturer in Bandung. Using a quantitative approach with interviews, documentation, and observation, the research applied the DMAIC (Define, Measure, Analyze, Improve, Control) framework to identify and address quality issues. Key defects included joint cracks, under-fill, and press marks. Analysis using Pareto charts and cause-and-effect diagrams revealed root causes such as inadequate operator training, inconsistent raw materials, and irregular machine maintenance. To address these, the company implemented retraining programs, improved standard operating procedures, and adopted digital monitoring systems. As a result, the defect rate was reduced by 40%, and the sigma level improved from 3.9 to 4.45. The study confirms that Six Sigma can significantly enhance both product quality and operational performance. These findings offer valuable insights for other MSMEs aiming to adopt structured quality improvement methods to remain competitive in the global market.

Abstract

UMKM Tahu XYZ, a small-scale tofu producer, is currently facing significant challenges in maintaining consistent product quality, primarily due to a high defect rate. Common issues identified include crumbled tofu shapes, overly soft textures, and inconsistent taste, which negatively impact customer satisfaction and business sustainability. This study aims to investigate the root causes of these quality issues and propose practical solutions using the Lean Six Sigma methodology. The research employs a descriptive quantitative approach through the DMAIC framework—Define, Measure, Analyze, Improve, and Control—to ensure systematic problem-solving. Data were collected over a six-month period through direct observation, structured interviews, and review of production records. The analysis identified four dominant types of waste within the production process: unnecessary transportation, product defects, excessive movement, and over-processing. The root causes of these inefficiencies are linked to poor handling of raw materials, variability in soybean quality, and an ineffective production layout that hampers workflow and consistency. To address these problems, the study proposes several targeted interventions, including the redesign of the production layout to optimize flow, the implementation of the 5S (Sort, Set in order, Shine, Standardize, Sustain) workplace organization method, the development of standardized operating procedures (SOPs), and the adoption of improved soybean boiling technology. The implementation of these improvements is projected to significantly reduce product defects, enhance process efficiency, and ultimately increase customer satisfaction. Furthermore, these actions are expected to improve the overall competitiveness of UMKM Tahu XYZ within the highly demanding food industry sector. This research provides actionable insights for other micro, small, and medium enterprises (MSMEs) seeking to apply structured quality control methods to strengthen operational performance and long-term business resilience.

Abstract

This study aims to analyze and improve the quality control of packaging printing production at PT XYZ by applying the Lean Six Sigma methodology. Lean Six Sigma combines waste reduction principles with statistical quality control to achieve operational excellence. The research identifies major production challenges, including high defect rates, overproduction, and ineffective inventory management, all of which contribute to increased costs and reduced efficiency. The DMAIC framework—Define, Measure, Analyze, Improve, and Control—was employed to systematically address these issues. During the Define and Measure phases, types of waste were identified and defect rates were calculated using Defects Per Million Opportunities (DPMO). In the Analyze phase, root causes were examined using a Fishbone (Ishikawa) diagram, highlighting factors related to manpower, materials, machines, and methods. The analysis revealed a sigma level of 3.2, indicating a moderate level of process quality and substantial room for improvement. To address the identified issues, several improvement strategies were proposed. These include implementing a Just-In-Time (JIT) system to reduce inventory waste, adopting the First-In-First-Out (FIFO) inventory method for better material rotation, and conducting targeted technical training for operators to minimize human error. In the Control phase, the study suggests process standardization, routine inspections, and continuous monitoring as key practices to ensure that improvements are sustained over time. The findings and recommendations from this study are expected to contribute to better quality control, reduced operational waste, and enhanced productivity in the packaging printing process. Ultimately, this approach aims to strengthen PT XYZ’s competitiveness in the printing industry by fostering a culture of continuous improvement and quality excellence.
