Recognizing the critical need for advanced risk management in the rapidly expanding construction sector, this study aims to analyze and optimize construction risk mitigation strategies at a prominent Indonesian housing developer, enhancing project time efficiency and reducing decision-making uncertainty. The research methodology employs a quantitative descriptive approach, utilizing Markov Decision Process to model project risk dynamics and Reinforcement Learning, specifically the Q-Learning algorithm, to determine optimal mitigation policies. Data collection involved direct observation, in-depth interviews with project management, and analysis of historical project documentation from a housing project. Research findings demonstrate that the Q-Learning model effectively identifies and recommends adaptive mitigation strategies for various risk levels, providing optimal actions that significantly reduce project delays. The implementation of these data-driven strategies resulted in a notable improvement in project time efficiency, reducing the average project duration. Reproducibility, convergence, and sensitivity tests further validate the model's reliability and robustness, confirming its capacity to provide consistent and stable recommendations under diverse conditions.

Utilizing digital technology in business enhances competitive advantage, significantly improving performance, particularly for small and medium firms. (UKM). This study seeks to investigate the impact of social media marketing and the integration of financial technology (FinTech) on company performance, with competitive advantage serving as a mediating variable within the small and medium-sized companies (SMEs) of the Lombok pearl sector. The study methodology employs a quantitative approach utilizing Structural Equation Modeling-Partial Least Squares (SEM-PLS) analysis. The research sample comprises 120 players in the Lombok pearl industry SMEs utilizing social media marketing and finance technology, selected via the census technique through the SME association. The research findings indicate that social media marketing does not immediately boost company performance; nonetheless, it greatly adds to the augmentation of competitive advantage, which subsequently enhances business performance. The implementation of financial technology significantly influences corporate performance and enhances competitive advantage. Moreover, competitive advantage has demonstrated its role as a mediating variable that enhances the association between social media marketing and the adoption of financial technology in relation to company success.
