Abstract

This study aims to develop and implement an efficient and effective e-commerce-based electronic goods sales system using the Extreme Programming (XP) system development method. The main focus of this research is to enhance the promotion and sales processes in small and medium-sized stores to be competitive in the digital era. XP was chosen due to its iterative and incremental approach and customer involvement at every stage of software development to ensure the final product meets user needs and expectations. The results indicate that the developed system can expand customer reach and improve the operational efficiency of these stores.

Abstract

Accurate quantity take-off is essential for reliable construction cost estimation, particularly in reinforced concrete works, which involve complex and error-prone calculations. This study evaluates the accuracy of BIM 5D-based quantity take-off and examines cost deviations compared to conventional contractor estimations. A three-story dormitory building was modeled using BIM 5D (Cubicost), and the results were validated against manual analytical calculations. The validation shows strong agreement, with a maximum deviation of 0.75% and a high linear correlation across concrete, reinforcement, and formwork quantities. A comparative analysis with the contractor’s Bill of Quantity reveals a cost difference of approximately 3.4%, with the contractor’s estimate being higher. This deviation is primarily attributed to simplifications in conventional methods, including double counting at element interfaces, generalized reinforcement detailing, and the inclusion of material allowances. In contrast, BIM 5D enables a more integrated and precise estimation by accounting for element interactions and optimizing reinforcement configurations. However, the results also highlight that BIM-based estimation is sensitive to modeling assumptions and parameter settings. Therefore, aligning BIM models with actual construction practices is essential to ensure reliable and applicable results. Overall, this study demonstrates the potential of BIM 5D to enhance the accuracy, consistency, and transparency of construction cost estimation.

Abstract

This study analyzes the empowerment strategy of functional employees at the Department of Food Security and Agriculture of Bintan Regency through a Dynamic Capabilities approach. The research used a qualitative descriptive method with data collected through interviews, observations, and documentation. The findings show that employee empowerment has been implemented through the dimensions of sensing, seizing, and reconfiguring. Functional employees are involved in monitoring activities, technical programs, and organizational adaptation processes. However, several challenges remain, including competency gaps, limited technical training, and inadequate integration of information systems. The study concludes that strengthening competency development, adaptive management, and merit-based human resource systems is essential to support organizational effectiveness after bureaucratic simplification. The Dynamic Capabilities approach is relevant for improving the adaptability and performance of public organizations in facing administrative reform and environmental changes
