This study examines the strengthening of regional disaster management governance through a risk-based policy framework, focusing on the role of local governments in disaster-prone areas. The object of the study is the disaster management system implemented by the Dumai City Regional Disaster Management Agency (BPBD), which faces various potential natural and non-natural disasters. Although national and regional regulatory frameworks are in place, disaster management practices at the regional level still tend to be reactive, partial, and not fully based on comprehensive risk analysis. Therefore, this study aims to identify key issues in regional disaster management governance and analyze the role of risk-based policies in strengthening institutional effectiveness, cross-sectoral coordination, and disaster preparedness. This study uses a qualitative descriptive approach with data collection techniques through in-depth interviews with BPBD officials, relevant stakeholders, and community representatives in disaster-prone areas, supported by field observations and documentation studies of policies, disaster risk assessment documents, and institutional reports. Data analysis was conducted using thematic analysis methods to identify patterns related to governance structures, policy implementation, and disaster risk management practices. The study results indicate that disaster management governance in Dumai City has shown progress in regulatory aspects and emergency response capacity, but there are still weaknesses in the integration of risk into development planning, inter-agency coordination, community participation, and mitigation and prevention efforts. This study concludes that the implementation of a risk-based policy framework can encourage more anticipatory, integrated, and sustainable disaster management governance, and provides important implications for the formulation of public policy at the regional level.

This study explores the role of sentiment analysis as a predictive tool for understanding and forecasting product launch success in the digital market. Sentiment analysis involves the classification of consumer sentiment expressed on social media platforms such as Twitter and Instagram, and it can significantly impact businesses by predicting consumer behavior and product performance. The research highlights the relationship between social media sentiment and product success, demonstrating that positive sentiment is strongly correlated with higher sales and consumer engagement, while negative sentiment can lead to declines. Machine learning models, including Support Vector Machines (SVM) and Random Forest, were employed to classify sentiment from large volumes of social media data and correlate it with product performance indicators such as sales volume and consumer interaction. The study found that sentiment analysis models were highly effective in predicting product success, with positive sentiment generally driving product profitability and negative sentiment posing a potential threat to brand reputation. Moreover, the analysis showed that social media sentiment provides real-time insights into consumer perceptions, enabling businesses to quickly adjust marketing strategies and product development plans. These findings underscore the importance of integrating sentiment analysis into product launch evaluations and strategic decision-making. Future research should explore the integration of sentiment analysis with other predictive market models and investigate the effects of fake reviews and post-purchase consumer behaviors on product success.
