In the regulated field of medical device manufacturing, optimizing production efficiency without compromising compliance is critical particularly for small and medium-sized enterprises (SMEs) operating in resource-constrained environments. This study addresses production inefficiencies in the assembly of the TSN 89 TR neonatal incubator at PT Tesena Inovindo, an Indonesian manufacturer, by implementing an integrated improvement framework. The approach combines Lean Manufacturing for process stabilization, the Ranked Positional Weight (RPW) method for line balancing, and the Theory of Constraints (TOC) for bottleneck resolution. Time study data were collected across 30 cycles per task to ensure reliable estimates of average cycle times, based on the Central Limit Theorem. The initial production system exhibited unbalanced workloads, high idle time, and frequent work-in-process (WIP) accumulation. After reconfiguration, the number of workstations was reduced from ten to eight, cycle time decreased by 23.8%, and daily output increased from four to six units. Line efficiency improved from 67.2% to 89.5%, with idle time dropping from 32.8% to 10.5%. These gains were achieved without automation or additional labor, relying solely on empirical task analysis and workflow redesign. The study offers a replicable, low-cost framework for optimizing semi-manual assembly lines in regulatory environments. It demonstrates that substantial performance improvements can be achieved through structured, data-driven interventions, making it particularly valuable for SMEs in emerging markets seeking ISO 13485 compliance and operational excellence

MSMEs Pempek Koyek is a business engaged in the production of traditional Palembang food facing several challenges, including a decline in sales due to the COVID-19 pandemic, limited promotional activities, lack of an online store, and a less strategic location. This study aims to identify and analyze the internal and external factors affecting the business and formulate effective strategies for growth. A mixed-methods approach was adopted, using SWOT analysis and the Business Model Canvas (BMC) framework. Data collection included observations, interviews with owners, customers, and stakeholders, and surveys distributed to 122 respondents identified using Slovin's formula. The SWOT analysis revealed that the company is positioned in Quadrant I, suggesting the adoption of an aggressive Strength-Opportunity (S-O) strategy. Key strategies include using social media and e-marketplaces to promote high-quality products, forming strategic partnerships with the hospitality industry, diversifying product offerings, enhancing social media engagement, and optimizing customer service with faster delivery. The BMC approach focused on improving key activities such as raw material sourcing, product innovation, and digital marketing. The results of this study provide valuable insights into the strategic development of MSMEs, particularly in the food sector, by combining internal strengths with external opportunities. The findings contribute to the growing body of knowledge on MSME development and offer practical strategies for business sustainability in a competitive market environment.
