Abstract

The Indonesian government has implemented various measures to prevent the spread of the COVID-19 virus, one of which is through a vaccination program with two doses (the first dose and the second dose). However, new variants of the virus have emerged, reducing the effectiveness of the initial vaccinations. To address this, the government introduced a booster vaccination program aimed at enhancing immunity by up to 80%. The government's plan for booster vaccination has received both positive and negative opinions from the public through various media platforms, including Twitter. This study analyzes public opinions on the booster vaccination plan into three classes: positive, negative, and neutral. SVM is a classification method in machine learning categorized as supervised learning, which involves finding an optimal line (hyperplane) as a separator for two different data classes. The stages of this research include data collection, data cleaning, data transformation, and data classification using the Support Vector Machine (SVM) method. The results of this study indicate that the accuracy of the SVM model reaches 80.42%.

Abstract

Initiatives for Smart Cities present an acceptable solution to the issues of urban administration as urbanization gains increasing speed. However, the success of smart city initiatives depends on citizen awareness and participation. This study aims to identify the key determinants of awareness and participation in Smart City initiatives among Sri Lankan citizens. A cross-sectional survey was conducted using a structured self-administered questionnaire distributed via social media, with 200 respondents from all nine provinces. Convenience sampling was employed to ensure broad participation. Findings indicate that access to ICT, digital literacy, and community engagement significantly enhance awareness, which in turn fosters participation. Notably, perceived benefits do not significantly impact awareness but directly negatively affect participation, suggesting that concerns over potential risks may deter engagement despite increased awareness. These findings suggest that while community engagement, digital literacy, and access are useful for raising awareness, resolving citizens’ concerns about the potential risks of smart city initiatives is essential to increasing participation. Policymakers must prioritize trust-building measures and community engagement to overcome barriers to Smart City adoption. Future research could examine these relationships longitudinally and explore additional factors such as trust in government and technology acceptance.

Abstract

This study presents a systematic review according to the PRISMA protocol on digital nudging strategies, applications, and limitations. The PICOC framework has been used to refine the research questions and develop the inclusion criteria. This review synthesizes findings from diverse sectors such as financial services, sustainability, cybersecurity, and workplace management, showing how organizations use digital nudging to drive user behavior. The findings indicate that the effectiveness of digital nudging is contingent on technological infrastructure, organizational culture, sector-specific constraints, and regulatory compliance. AI-driven and data-intensive interventions enhance the efficacy of digital nudging but simultaneously raise concerns related to privacy, algorithmic bias, and transparency. Ethical considerations, including autonomy, informed consent, and fairness, continue to be decisive in determining the legitimacy and acceptance of nudging interventions across various contexts. Furthermore, the cross-sectoral adaptation of successful strategies for nudging offers further opportunities for enhanced engagement and behavioral change in new domains. By and large, future research is called upon to develop sector-specific ethical guidelines, determine the long-term behavioral consequences of nudging interventions, and increase transparency in AI-driven nudging systems to ensure accountability, user trust, and responsible implementation.
