This study presents a Systematic Literature Review (SLR) focusing on the application of the Branch and Bound (B&B) method in production optimization. In modern industry, achieving operational efficiency and profitability is essential, yet optimization often yields fractional solutions that are unrealistic for indivisible entities. The Branch and Bound method, as part of Integer Programming, has proven effective in addressing these constraints by converting fractional solutions into optimal integer values. This SLR analyzed 12 scientific articles published between 2016 and 2024, sourced from databases such as Google Scholar, Scopus, and SINTA. The analysis reveals that B&B is widely utilized to maximize production profit across various sectors, including spring beds, woven fabrics, bread, and furniture, often formulated as Integer Linear Programming (ILP) problems. Furthermore, this method is also applied to minimize production time and determine the shortest routes. Overall, B&B is a flexible and efficient tool that assists companies in managing resources and achieving maximum profit with realistic integer solutions.

Operational efficiency is one of the key indicators in determining the success of industrial companies amid increasing competition. One of the strategies that can be implemented to improve this efficiency is through systematic and integrated business process management. This study aims to examine the role of business process management in enhancing the operational efficiency of industrial companies. This research uses the literature review method by analyzing various national journal publications from the last five years relevant to the topic. The results show that implementing effective business process management helps companies reduce waste, shorten production time, and improve product quality. The utilization of information technology, particularly ERP systems, supports the integration of business processes, allowing for more effective decision-making. However, several challenges remain, including resistance to change and limitations in human resources. Therefore, the implementation of business process management requires appropriate strategies and active participation from all organizational elements to achieve the desired efficiency.   Keywords: , , , ,

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.

Climate change and environmental degradation have negatively impacted mankind's sustainable development. The concept of green entrepreneurship has gradually been accepted by society, including ecoprint batik. Through the application of zero waste, ecoprint batik production offers a strategy that is in line with the principles of green entrepreneurship. This study aims to analyze the application of zero waste to the efficiency of eco-print batik production in the context of green entrepreneurship. The method used in this study is a qualitative approach with secondary data collection on batik business actors in Sragen. The data obtained were then analyzed using descriptive analysis to identify the analysis of the application of zero waste in batik innovation towards green entrepreneurship efforts. The results of the study indicate that the application of zero waste in eco-print batik production has a significant impact on production efficiency, especially in reducing waste and optimizing the use of raw materials.

Optimization of primary and secondary packaging is crucial for the quality and efficiency of drug production. The drug packaging process consists of primary packaging that is in direct contact with the product and secondary packaging that provides additional protection and important information. This study aims to analyze various methods applied in pharmaceutical packaging to assess the effectiveness of Lean Manufacturing (VSM), Single Minute Exchange of Dies (SMED), and Overall Equipment Effectiveness (OEE). This study shows that VSM significantly reduces the time of secondary packaging activities. SMED reduces the lead time of primary packaging analysis by 58.06%. Meanwhile, OEE analysis of primary packaging identified high set-up/adjustment as the main cause of losses. The importance of implementing structured methods to increase productivity, reduce waste, and ensure a more efficient and effective packaging process in the pharmaceutical industry, contributing to improving product quality and safety.

Cost theory is one of the fundamental concepts in economics that explains how firms allocate resources to produce goods or services. In economic analysis, costs are categorized into short-run and long-run costs. In the short run, there are inputs that are fixed, limiting the firm's ability to adjust the scale of production. This leads to the concepts of fixed costs and variable costs. In contrast, in the long run, all inputs are variable, giving firms full flexibility to adjust their scale of production, which results in the formation of the long-run cost curve. This curve serves as an envelope of various short-run cost curves and reflects production efficiency at different scales. Understanding the differences between short-run and long-run costs is essential for firms in making decisions, particularly in production planning and long-term investment.

Productivity refers to the efficiency with which goods and services are produced, measured using the ratio of outputs produced to inputs in the production process.
