Abstract

This Community Service Program focuses on improving the efficiency and traceability of healthcare services through the digitization of administrative processes and workflows. Common challenges faced by our partners include long wait times, duplicate record-keeping, difficulty tracking files, delays in claims processing and billing, and an unbalanced workload for staff. Interventions are implemented through mapping of current processes, baseline measurements (wait times, turnaround times), design of digital workflows, development of standard operating procedures (SOPs), implementation of electronic forms and queue management systems, and a dashboard for monitoring capacity and workload. Success is measured by reductions in wait times, improved data accuracy, accelerated service processes, and increased staff productivity.

Abstract

This Community Service (PkM) activity aims to strengthen the SME ecosystem through collaboration between the government and the business sector by developing an operational partnership model and a measurable stakeholder relationship management system. Common challenges include fragmented SME support programs, limited market access and financing, inconsistent quality standards, and cross-sector coordination that lacks established working mechanisms and shared indicators. The PkM intervention is carried out through mapping of stakeholders and SME needs, designing partnership models (governance, roles, service workflows), developing joint program packages (market access, product upgrading, financing, digitalization), and establishing a coordination platform in the form of a partnership forum and a KPI dashboard. Key outputs include partnership model documents, MoU/MOU templates, collaboration SOPs, stakeholder maps, and a 12-month action plan ready for implementation.

Abstract

This study aims to develop and test an impact measurement system that integrates global supply chain risks with a company’s financial performance. Supply chain risk—arising from both internal and external factors can lead to operational disruptions, increased costs, and disturbed cash flows, thereby affecting key financial performance indicators such as ROA, ROE, NPM, CR, and DER. The research uses a quantitative approach with Structural Equation Modeling (SEM) based on AMOS, along with scenario analysis and what-if simulations to assess the effects of specific disruptions. The findings indicate that financial risk and operational risk are the dominant factors exerting significant negative effects on financial performance: financial risk notably reduces ROA and ROE, while operational risk affects NPM through higher costs and margin compression. Geopolitical and environmental risks, though showing more moderate effects, still influence overall operational stability and financial performance. Managerial recommendations include supplier diversification, implementing Supply Chain Finance (SCF), using real-time monitoring technologies and developing risk-specific contingency plans.

Abstract

This study aims to develop and test an impact measurement system that integrates global supply chain risks with a company's financial performance. Supply chain risk—originating from both internal and external factors—can cause operational disruptions such as process failures and shipping delays, increase operational costs, and disturb cash flows, thereby affecting financial performance indicators. Specifically, the research examines the effects of operational risk, financial risk, geopolitical risk, and environmental risk on financial performance measures including Return on Assets (ROA), Return on Equity (ROE), Net Profit Margin (NPM), Current Ratio (CR), and Debt to Equity Ratio (DER). The methodology applies a quantitative approach using Structural Equation Modeling (SEM) with AMOS, along with scenario analysis and what-if simulation to assess the impact of specific disruptions—for example, a 20% increase in logistics costs or critical shipment delays. The findings indicate that financial risk and operational risk are the dominant factors exerting significant negative effects on financial performance: financial risk notably reduces ROA and ROE, while operational risk affects NPM through increased costs and margin compression. Geopolitical and environmental risks, although showing more moderate effects, still influence overall operational stability and financial performance. The study provides managerial implications, including supplier diversification, implementation of Supply Chain Finance (SCF), adoption of real-time monitoring technologies (eg, IoT and predictive analytics), and formulation of contingency plans and risk-specific mitigation strategies.

Abstract

This study qualitatively examines the comparative business-scaling strategies of MSMEs: a high-technology approach versus a conservative model. Amid ongoing digital transformation, MSMEs face the need to adapt in order to strengthen competitiveness. The high-technology strategy focuses on digital marketing and sales, product innovation driven by market-trend and customer-preference analysis, and operational efficiency through systems such as ERP to streamline supply-chain management. In contrast, the conservative model tends to maintain manual operational practices and conventional, offline marketing. Although it may provide operational stability, it often limits innovation, reduces responsiveness to market dynamics, and constrains access to digital segments. Data were collected through in-depth interviews, field observations, and document studies. The findings indicate that adopting a high-technology strategy can enhance business performance by expanding market reach, enabling product differentiation, and improving operational efficiency. However, it requires substantial initial investment and organizational culture change, which is not always easy for all MSMEs. Therefore, the study recommends an integrative model: selective/partial digital transformation in key areas such as marketing, data management, and product innovation—while preserving proven traditional operational foundations. This should be supported by strengthening digital literacy and human-capital capacity, as well as collaboration among MSMEs and communities to accelerate innovation and optimize performance

Abstract

This Community Service Program (PKM) activity aims to strengthen the MSME supply chain through the implementation of efficient inventory and distribution management. The main problems faced by partners include inaccurate stock, frequent stockouts/overstocks, the absence of a reorder point, untidy inventory recording, and unmeasured distribution costs. The program is implemented through supply chain process assessments, training and workshops on inventory recording, establishing stock policies (minimum-maximum/ROP), improving simple warehouse layouts and flows, distribution planning (routes, schedules, delivery consolidation), and assistance in implementing tools (stock cards/Excel/Google Sheet). The outputs include inventory and distribution SOPs, recording templates, indicator dashboards, and implementation trials on participating MSMEs. The targeted results are increased stock accuracy, reduced stockouts, and distribution cost efficiency.
