Abstract

This research delves into the efficacy of police communication strategies in combating drug abuse among teenagers in Simpang Kanan Subdistrict, situated within the Rokan Hilir Regency of Indonesia. Utilizing a mixed-methods approach, the study navigates the intricate interplay of cultural dynamics, community engagement, and the effectiveness of varied communication channels employed by law enforcement agencies. Quantitative analysis unveils statistical trends in drug abuse prevalence among teenagers, shedding light on the impact of specific communication strategies. Concurrently, qualitative exploration delves into perceptions, experiences, and stakeholder feedback, offering depth to the understanding of the multifaceted issue. Findings underscore the strengths of community engagement initiatives and diverse communication channels, showcasing heightened awareness and positive behavioral shifts among teenagers. Yet, limitations such as data constraints, sampling intricacies, and resource limitations temper the comprehensiveness of the analysis. The implications drawn from this research advocate for tailored, culturally sensitive approaches, community-driven interventions, and continuous evaluation mechanisms in future policy changes. These insights transcend regional boundaries, offering a framework adaptable to analogous contexts worldwide. This research serves as a beacon, illuminating pathways toward combating teenage drug abuse.

Abstract

Dairi Regency, a region nestled in the natural splendor of North Sumatra, holds the promise of becoming an economic hub, fueled by the strategic development of tourism and culture. This research explores the multifaceted strategies necessary to enhance Original Regional Income by leveraging the wealth of cultural heritage and the allure of natural beauty. Cultural preservation and promotion emerge as key drivers of this transformation, recognizing the value of the unique Batak culture in attracting tourists seeking authentic experiences. Infrastructure development is an essential foundation, as improved connectivity and accommodations facilitate access to Dairi Regency's cultural and natural treasures, fostering tourism and economic growth. The path to a more inclusive and sustainable future is illuminated by community-based tourism (CBT). Engaging local communities in tourism activities and decision-making processes ensures equitable distribution of tourism benefits and enhances the region's authenticity. Diversification of tourism products broadens the audience, welcoming travelers with diverse preferences. The research outlines a structured planning approach, guided by SWOT analysis, enabling adaptive strategies that align with changing circumstances. Balanced spatial development, driven by GIS analysis insights, ensures economic prosperity is distributed evenly across the region. Sustainability and responsible tourism practices underline the importance of ethical and environmentally conscious tourism, contributing to long-term success. Collaboration between the community and government agencies strengthens the region's commitment to collective ownership of economic development. Transparent measurement of economic impact fosters trust and engagement. This research not only unveils the untapped potential of Dairi Regency but also presents a comprehensive roadmap for realizing this potential. It provides insights and strategies for the Tourism and Culture Department, local authorities, and stakeholders to shape a sustainable, inclusive, and culturally rich economic future for the region.

Abstract

The rapid adoption of machine learning (ML) in the public sector has increased the need for transparent, accountable, and trustworthy algorithmic decision-making, particularly in high-stakes domains such as social welfare, healthcare, security, and public administration. However, existing approaches to explainable machine learning (XML) remain fragmented, focusing primarily on technical explanation techniques without integrating the institutional, ethical, and user-centered requirements of government environments. This research aims to develop a unified theoretical practical framework that operationalizes explainability across the entire ML lifecycle for critical public-sector applications. This study adopts a qualitative, multi-stage research design that combines theoretical synthesis, framework construction, and empirical validation through expert assessment and case-based evaluation.The results demonstrate that explainability is a multidimensional construct that extends beyond algorithmic transparency to include contextual risk assessment, adaptive explanation delivery, and governance mechanisms such as auditability, human oversight, and documentation standards. The proposed framework integrates four interconnected layers context analysis, model design and transparency, explanation delivery, and oversight and governance providing a structured pathway for implementing explainable ML systems that meet public-sector standards of fairness, legitimacy, and accountability. Expert feedback and case evaluations confirm that the framework enhances interpretability, reduces misinterpretation risks, and supports more informed decision-making among stakeholders. This research contributes to the advancement of responsible AI in government by offering a comprehensive model that bridges technical methods with policy and practice, paving the way for more transparent and trustworthy ML adoption in public-sector services.

Abstract

Rat infestation by Rattus argentiventer remains a serious problem in irrigated rice fields, causing significant yield losses and threatening sustainable rice production. Conventional control methods rely heavily on chemical rodenticides, which pose environmental risks and show declining long-term effectiveness. Ultrasonic deterrent technology has been proposed as an alternative; however, its effectiveness in open-field agricultural environments remains inconsistent and poorly understood. This study aims to analyze the behavioral and migration responses of rice field rats to different ultrasonic frequency ranges to clarify the mechanisms underlying ultrasonic deterrence. A field-based experimental design was applied using paired treatment and control plots, with ultrasonic frequencies ranging from 20 to 40 kHz. Rat activity and movement were monitored through camera traps and motion sensors, and spatial behavior was analyzed using activity reduction rates, migration distance, and path deviation indices. The results indicate a clear frequency-dependent response, with ultrasonic exposure at 30–35 kHz producing the strongest avoidance behavior and directional displacement. These findings suggest that ultrasonic deterrence primarily induces spatial displacement rather than population elimination and provide important implications for the development of adaptive ultrasonic–IoT systems to support smart and sustainable pest management in rice agriculture.

Abstract

Rat infestation remains a major constraint to rice production, causing significant yield losses and threatening food security in many rice-growing regions. Although ultrasonic deterrent systems have been promoted as an environmentally friendly alternative to chemical rodenticides, their effectiveness is often inconsistent due to static frequency emission and rapid behavioral habituation. This study proposes an adaptive scheduling model for ultrasonic frequencies based on real-time environmental data to enhance long-term deterrence effectiveness. The model integrates environmental sensing, stochastic frequency selection, and habituation-aware control within a context-aware scheduling framework. Environmental data were acquired using field-deployed sensors, while the adaptive algorithm dynamically adjusted ultrasonic frequency, emission duration, and interval. Field evaluations compared the proposed system with static ultrasonic control. Results demonstrate sustained spectral diversity, reduced habituation, and significant decreases in rat activity and crop damage, alongside improved energy efficiency. These findings highlight the potential of adaptive ultrasonic control as a scalable and sustainable solution for smart agriculture, supporting chemical-free pest management and precision rice farming.
