Abstract

Background. Public understanding of ENT (ear, nose, and throat) diseases remains low. Many people still rely on experts manually, resulting in high costs for the general public. Aims. This research was conducted to develop a tool to assist users in diagnosing ENT (ear, nose, and throat) diseases in humans. This tool, an expert system, is designed to diagnose and provide herbal treatment recommendations. Result. This expert system application produces an application program or tool that can be used to diagnose possible ENT diseases in humans based on user-entered symptoms. Conclusion. System testing demonstrated that the system can diagnose ENT diseases based on patient symptoms, despite the uncertainty of those symptoms. Implementation. The diagnostic results are accompanied by a Certainty Factor value, which indicates the level of accuracy and predictability of the possible ENT disease in humans, along with the corresponding herbal treatment.

Abstract

Background. This research discusses the digitization of the Prince Cakrabuana Museum through the development of a website-based cultural asset management information system. The background of this research is that the accessibility and efficiency of museum information management remain limited in conventional ways, which affects the dissemination of information and public museum promotion. Aims. This research aims to design and implement a website-based information system that supports the processes of cultural asset inventory, collection documentation, and digital museum information delivery. Methods. The research method used is a qualitative descriptive case study, conducted at the Cirebon Regency Culture and Tourism Office. Data collection techniques are carried out through observation, interviews, and documentation during Field Work Practice (PKL) activities. Result. The results of the study show that the developed system can manage cultural asset data more structurally, increase public access to information, and support the digital promotion of the Prince of Cakrabuana Museum. Conclusion. The conclusion of this study shows that the application of a website-based information system can improve the efficiency of museum asset management and public interest in the preservation of cultural heritage.

Abstract

Background. This study deals with a System Dynamics (SD) model to investigate technology transition under resource constraints, using small-scale catfish farming as a case study. In this context, land availability constitutes the resource constraint. To address this constraint, it is necessary to achieve catfish productivity gains through technological intensification, such as the use of aquaponics. Methods. The SD model captures feedback interactions among production, operating costs, revenue, profit, and reinvestment by setting aside a portion of profits. The SD model's behavior is analyzed by generating six scenarios over 25 years to examine the effects of feed price fluctuations, fingerling price fluctuations, and alternative reinvestment rates. Model outcomes were evaluated using production, profitability, and the benefit–cost ratio (BCR) as an economic performance indicator. Result. The results show that feed and fingerling price fluctuation exerts a strong negative effect on profitability and economic feasibility, while higher reinvestment rates accelerate aquaponics adoption and improve long-term performance. Conclusion. BCR analysis indicates that technology transition in land-limited catfish farming is feasible only when BCR remains above unity, supporting sustained reinvestment. Implementation. The study highlights the importance of reinvestment strategies and feed and fingerling costs management in enabling resilient technological upgrading in spatially constrained aquaculture systems.

Abstract

Background. Lean Management and Lean Construction have been widely recognized as effective approaches to improving efficiency, reducing waste, and enhancing organizational performance. However, the readiness of construction organizations—particularly State-Owned Enterprises (SOEs)—to implement Lean Management remains insufficiently explored, especially in developing countries. Aims. This study aims to assess the factors influencing Lean Management implementation and to evaluate the readiness level of Indonesian construction SOEs using a quantitative approach. The research adopts Lean Management as its theoretical foundation and applies the Lean Construction Maturity Model (LCMM) as the primary measurement framework to capture organizational readiness comprehensively. Methods. Data were collected through a structured questionnaire distributed to management-level respondents across six Indonesian state-owned construction companies, involving division heads, section managers, staff, and project managers, with a total sample of approximately 250 respondents. The analysis employs linear regression within a structural model to examine the relationships among key readiness factors, including leadership, culture and behavior, competence, continuous improvement support, processes and tools, organizational change, work environment, business results, and learning and competency development. Result. The findings are expected to provide empirical insights into the interdependencies among these factors and to identify critical readiness gaps that may hinder effective Lean Management implementation. Conclusion. This study contributes theoretically by extending the application of LCMM to Lean Management readiness assessment and practically by offering a structured diagnostic framework for SOEs seeking to enhance Lean adoption in the construction sector.
