Abstract

Operational inefficiency is often caused by uneven workload distribution and unplanned job sequencing. Both factors lead to bottlenecks, prolonged waiting times, and ineffective resource utilization. This study investigates how workload optimization and sequencing decisions contribute to improving operating system efficiency. Using a descriptive literature study approach based on secondary data from sources on organizational behavior and operations management, the findings indicate that workload imbalance causes bottlenecks and declining workforce performance, while unstructured sequencing prolongs makespan and increases idle time. Priority rules such as Shortest Processing Time and Earliest Due Date can demonstrably shorten total completion time while improving resource utilization, whereas workload equalization has been shown to reduce operational disruptions. This study finds that addressing both variables simultaneously produces greater efficiency gains than handling them separately. Practitioners are advised to periodically assess workload distribution and apply sequencing methods suited to their respective production characteristics.

Abstract

Shallot trading businesses face persistent challenges in supply chain coordination, particularly regarding unstable agricultural yields, pest infestations, and volatile commodity prices, which demand a more structured information management system. This study aims to examine how the Enterprise Resource Planning (ERP) framework can strengthen supply chain operations at Gudang Bawang Jonpiter Silaen in Medan City. A qualitative case study design was adopted, with in-depth interviews conducted with the business owner as the primary data source, supplemented by academic literature. Findings reveal that the business operates through interconnected stages sourcing shallots from farmers, warehouse storage, product grading, and distribution to market traders where existing documentation practices already mirror the core logic of ERP. The study concludes that transitioning toward a fully integrated ERP-based platform holds significant potential for improving operational productivity, reducing data inconsistencies, and sustaining a well-coordinated distribution network. It is recommended that the business gradually adopt a digital recording system that integrates procurement, inventory control, and sales transactions into a unified platform.

Abstract

Indonesia ranks second in global instant noodle consumption, reaching 14.26 billion servings in 2022, making product quality control a central concern for industry players. This study examines how Total Quality Management (TQM) principles are applied within Indonesia’s instant noodle industry and their relation to maintaining competitive advantage. A literature review method was used with a qualitative descriptive approach and content analysis of relevant academic sources. The study found that applying seven TQM elements, namely top management commitment, customer orientation, continuous improvement, employee involvement, production process control, supplier relationship management, and data-based decision making, contributes meaningfully to production efficiency, defect reduction, consumer trust, and global market competitiveness. This study offers a conceptual framework linking TQM, Quality Control, and Competitiveness specifically within the Indonesian instant noodle industry context, an area that has received relatively limited academic attention. Keywords: Total Quality Management (TQM), Quality Control, Industrial Competitiveness

Abstract

Small and medium enterprises (SMEs) often face limitations in implementing formal Research and Development (R&D), leading to reliance on informal practices based on experience and customer interaction. This study aims to examine how informal R&D contributes to product development and operational improvement in a small culinary business, namely Iko Denai Restaurant in Medan, Indonesia. A qualitative case study approach was employed, with data collected through in-depth interviews with the business owner and direct field observations. Source triangulation was applied to enhance data validity by comparing findings from different data sources. The results indicate that R&D activities are carried out informally through continuous interaction with customers, small-scale product trials, and ongoing evaluation of product quality and service. This approach enables the business to introduce new menu items with lower risk and adapt quickly to customer preferences. In addition, the decision to relocate the business to a more strategic location reflects a form of process innovation aimed at improving accessibility and customer convenience. The study highlights that informal R&D practices can effectively support innovation and business sustainability in SMEs, offering practical insights for small business development.
