Banda Aceh City has high vulnerability to tsunamis due to its coastal location directly facing the sea and being situated in an active tectonic zone. This study evaluates the spatial distribution of tsunami risk and assesses coastal conditions as disaster mitigation efforts using a mixed-method approach that combines quantitative analysis based on Geographic Information Systems (GIS) and qualitative analysis through field surveys and expert assessments. Three beaches were selected as study locations: Ulee Lheue Beach, Syiah Kuala Beach, and Alue Naga Beach, with risk assessment calculated using the formula Risk = (H × V) / C according to the BNPB framework and overlay techniques in GIS to create risk distribution maps. Coastal condition evaluation focused on coastal vegetation and protective coastal structures assessed using an ordinal scale of 1–5. Results show that Ulee Lheue Beach has the highest mitigation capacity with a score of 64.5% (good category), Syiah Kuala Beach reaches 57.5% (fairly good), while Alue Naga Beach has the lowest score of 28.3% (poor). Correlation analysis yielded a coefficient of r = 0.97, indicating a very strong positive relationship between coastal vegetation and protective coastal structures. Therefore, the study recommends strengthening mitigation strategies through improved protective infrastructure and optimization of coastal vegetation functions, particularly in high-risk areas, to reduce tsunami impacts in the future.

The increasing incidence of violence against women and children requires an active and effective role of public organizations in providing sustainable protection. This study aims to analyze the role of the Population Control, Women’s Empowerment, and Child Protection Office (DP5A) of West Sumba Regency in handling cases of violence against women and children. The research employs a descriptive qualitative approach. Data were collected through interviews, observations, and document analysis from purposively selected informants and analyzed using data reduction, data presentation, and conclusion drawing, supported by source and technique triangulation. The findings indicate that DP5A has performed its facilitative, educational, representative, and technical roles; however, their implementation has not been optimal. Major obstacles include limited facilities such as the absence of a permanent safe house, inadequate operational infrastructure, limited human resource capacity, underutilization of information technology and digital media, as well as cultural and administrative constraints. This study concludes that institutional strengthening, capacity building of personnel, optimization of technology utilization, and enhanced cross-sector collaboration are essential to improve the effectiveness of protection for women and children at the local level.

This study aims to assess the financial performance of the Sukoharjo Regency Government during the 2023-2024 period by employing cash flow statements as the primary analytical tool. Cash flow statements are considered essential as they provide a clear picture of liquidity conditions and the actual capacity of local governments to manage cash inflows and outflows. This research applies a descriptive quantitative approach using secondary data obtained from audited Budget Realization Reports and Cash Flow Statements. Financial performance is evaluated through revenue effectiveness ratios and expenditure efficiency ratios as key indicators of fiscal management. The results indicate that regional revenue realization consistently exceeded the established targets throughout the study period, placing revenue performance in the very effective category. This finding reflects the local government’s ability to maximize revenue potential during the post-pandemic economic recovery phase. However, the analysis of expenditure efficiency reveals that spending management has not yet reached an optimal level, as expenditure realization remained close to the allocated budget limits. These findings demonstrate that strong revenue performance does not necessarily correspond with efficient expenditure control. Consequently, local government financial performance should be evaluated comprehensively by integrating both revenue effectiveness and expenditure efficiency perspectives. This study contributes empirically to public sector accounting literature and offers practical insights for policymakers to strengthen budget control mechanisms and promote sustainable financial management at the regional level.    

The Muhammadiyah Orphanage in Pamekasan faces major challenges in developing life skills and digital education for its children due to limited facilities, teaching staff, and conventional learning methods. To address these issues, an edutainment-based approach and digital pedagogy intervention were implemented to enhance learning quality, motivation, and preparedness for future social and technological challenges. The activities included workshops and training on Digital Pedagogy and Edutainment learning materials, as well as simulations and role-plays using a Game-Based Learning approach, followed by evaluations and participant plan presentations. The program significantly improved the wards’ digital literacy, particularly in personal security (online safety), digital ethics (cyber ethics), gadget usage, and information management, with the average score rising from 2.84 to 4.10 on a 5-point scale, surpassing the target of 75% of participants in the “good” category. Beyond cognitive aspects, the program also boosted motivation, engagement, communication, problem-solving, and independence. Caregiver training was also provided to ensure program sustainability. It is recommended that the orphanage integrate the Game-Based Learning Digital Safety module into its non-formal curriculum, enhance caregiver capacity through advanced training, and improve IT infrastructure.

Educational inequality persists across ASEAN despite improvements in enrollment and literacy, reflecting structural rather than merely access-related challenges. This study examines how governance structures, financing mechanisms, institutional capacity, and socio-economic stratification interact to produce disparities in educational access, participation, and progression. Using a qualitative-dominant mixed-methods design with cross-national comparative policy analysis, the research integrates macro-level quantitative indicators with in-depth qualitative evaluation of policy frameworks across ASEAN member states. Findings reveal that while primary enrollment approaches universality, secondary and tertiary education exhibit pronounced attrition, particularly among rural, low-income, and minority populations. Centralized governance, equitable public financing, and targeted support correlate with higher retention and reduced disparities, as evidenced in high-performing systems such as Singapore, whereas decentralized or under-resourced systems exacerbate structural inequities. Moreover, digital access and institutional capacity emerge as critical factors influencing educational trajectories. The study underscores that addressing inequality requires systemic reforms integrating governance coordination, progressive financing, institutional strengthening, and equity-focused interventions. By foregrounding structural determinants and cross-national variation, this research contributes to theoretical and policy debates on educational equity, providing evidence-based guidance for ASEAN strategies aimed at achieving inclusive, high-quality education across diverse socio-economic and geographic contexts.

Steganography is a method to hide confidential messages in digital media so that they are not detected by unauthorized parties. Unlike cryptography which protects the content of messages through encryption, steganography hides the message itself. One popular technique is the Least Significant Bit (LSB), which replaces the least important bit on the pixel with a secret message bit. However, conventional LSB methods such as 1-bit or 3-bit have limitations due to the compromise between insertion capacity and visual quality of the media. This study proposes an LSB-based video steganography method with an adaptive multi-bit embedding approach. This technique determines the number and position of bits that are dynamically inserted based on the local brightness and texture levels of each video frame, with Laplacian operators used to analyze both high and low textured areas. The process includes frame and audio extraction, frame-by-frame embedding, inserted video reconstruction, and decoding using video cover references. The evaluation was carried out quantitatively using the Peak Signal-to-Noise Ratio (PSNR) and Structural Similarity Index (SSIM) metrics, as well as qualitatively through visual comparison. The results showed that the adaptive multi-bit method was able to maintain visual quality with a PSNR of 45.23 dB and SSIM of 0.9424, and increased the insertion capacity by up to 2–3 times compared to the 1-bit adaptive method. Thus, this approach effectively balances imperceptibility and insertion capacity on dynamic video steganography systems.  

Steganography is a technique for hiding secret data within digital media such as images, audio, and video without causing noticeable visual changes. In video media, this technique offers advantages because each frame can be utilized dynamically, resulting in a larger data embedding capacity. However, conventional methods such as fixed-number Least Significant Bit (LSB) embedding still face limitations in balancing visual quality, embedding capacity, and resistance to compression or noise. To address these challenges, this study proposes an Adaptive Video Steganography Method based on Multi-Bit LSB that employs brightness, texture, and motion analysis for each frame to determine the number of embedding bits adaptively. The system adjusts the embedding capacity according to the local characteristics of the video: areas with high texture or rapid motion are assigned more bits, while static or low-texture areas use fewer bits to preserve visual quality. After the embedding process, the video quality is evaluated using PSNR (Peak Signal-to-Noise Ratio) and SSIM (Structural Similarity Index Measurement) to assess its similarity to the original video. Experimental results show a PSNR value of 45.86 dB and an SSIM value of 0.9441, Thus, the proposed adaptive method proves to be efficient, robust against disturbances, and capable of maintaining data security without compromising visual quality, making it highly suitable for implementation in multimedia-based information security systems.

Video steganography faces fundamental challenges in balancing embedding capacity, imperceptibility, and robustness, where conventional Least Significant Bit (LSB) methods often produce visual artifacts such as flickering. To address this, this research proposes an advanced method named Adaptive Multi-layer LSB, which dynamically adjusts the number of embedded bits in each pixel based on a multi-factor analysis of the video's spatial and temporal characteristics. This adaptation mechanism is evaluated through three primary criteria: brightness level, local texture complexity, and inter-frame motion stability. Quantitative evaluation using Peak Signal-to-Noise Ratio (PSNR), Structural Similarity Index (SSIM), and Frame Difference Stability Index (FDSI) metrics demonstrates that the proposed method achieves high visual quality, with an average PSNR of 42.15 dB and SSIM of 0.985. These results significantly outperform the non-adaptive approach, which only recorded a PSNR of 38.5 dB. More importantly, the FDSI value of this method (1.25) is much lower compared to the non-adaptive approach (3.40), demonstrating its superiority in maintaining temporal stability. Thus, this approach provides a significant contribution to enhancing security and quality in video steganography practices. Abstract: Video steganography faces fundamental challenges in balancing embedding capacity, imperceptibility, and robustness, where conventional Least Significant Bit (LSB) methods often produce visual artifacts such as flickering. To address this, this research proposes an advanced method named Adaptive Multi-layer LSB, which dynamically adjusts the number of embedded bits in each pixel based on a multi-factor analysis of the video's spatial and temporal characteristics. This adaptation mechanism is evaluated through three primary criteria: brightness level, local texture complexity, and inter-frame motion stability. Quantitative evaluation using Peak Signal-to-Noise Ratio (PSNR), Structural Similarity Index (SSIM), and Frame Difference Stability Index (FDSI) metrics demonstrates that the proposed method achieves high visual quality, with an average PSNR of 42.15 dB and SSIM of 0.985. These results significantly outperform the non-adaptive approach, which only recorded a PSNR of 38.5 dB. More importantly, the FDSI value of this method (1.25) is much lower compared to the non-adaptive approach (3.40), demonstrating its superiority in maintaining temporal stability. Thus, this approach provides a significant contribution to enhancing security and quality in video steganography practices.

This research aims to enhance the imperceptibility of secret messages in video steganography to prevent detection by third parties. Unlike cryptography, which focuses on securing the message content, this method seeks to conceal the very existence of the message by maintaining a visual quality nearly identical to the original video. The proposed approach utilizes an adaptive multi-bit scheme based on the Least Significant Bit (LSB) technique, which intelligently analyzes the local characteristics of each frame, including brightness, texture, and motion. This strategy allows for higher data insertion in areas with high visual tolerance while limiting bits in sensitive areas to prevent distortion. Evaluation results using PSNR and SSIM metrics indicate that while increasing message capacity (from 1-bit to 3-bit) reduces the PSNR from 51.80 dB to 39.44 dB, the method remains highly effective in preserving visual integrity. Overall, this technique proves to be more secure and superior to traditional LSB in balancing storage capacity with high-quality video output.

Concurrent stunting and overweight/obesity (CSO) in adolescents represents a complex form of the double burden of malnutrition, characterized by linear growth faltering coexisting with excess body fat. This condition poses significant metabolic, cognitive, and reproductive risks that may affect long-term health and productivity. This review employs a narrative literature approach by synthesizing evidence from PubMed, Scopus, Web of Science, Google Scholar, and national journal portals. Included literature comprises studies assessing stunting, overweight/obesity, metabolic risk, cognitive function, and reproductive health among adolescents. Indonesian evidence (Harits et al., 2024) indicates that obese adolescents with a history of stunting exhibit a higher prevalence of metabolic syndrome (18.75%), greater abdominal adiposity, and elevated systolic blood pressure compared to non-stunted obese peers. Biologically, stunting impairs neurocognitive development and reduces muscle mass, while obesity promotes metabolic inflammation; the coexistence of these factors may reduce physical fitness, learning capacity, and overall productivity. CSO also affects reproductive health, including increased risks of ovulatory dysfunction, delayed sexual maturation, and intergenerational nutritional disadvantages. Although linear growth recovery is limited due to epiphyseal closure, functional recovery through improved diet quality and physical activity remains possible. In conclusion, adolescents with CSO experience greater metabolic, cognitive, and reproductive vulnerabilities than those affected by stunting or obesity alone. Interventions emphasizing metabolic function, diet quality, physical fitness, and reproductive health preparation are essential to prevent long-term consequences and break the intergenerational cycle of malnutrition. Further national research is required to map the prevalence and implications of CSO comprehensively.

Micro, Small, and Medium Enterprises (MSMEs) play a crucial role in the regional economy, including in Tatanga District and Nunu Village, Palu City. However, many MSME actors in these areas still face fundamental challenges such as low financial literacy, limited access to capital, and insufficient use of digital technology in business management. These limitations lead to weak financial record-keeping, poor cash flow management, and inadequate readiness to meet bankability requirements when applying for financing from formal financial institutions. This community service program was designed to improve the understanding and practical skills of MSME actors through financial literacy socialization, financial inclusion education, capital training in collaboration with financial institutions, and training in simple financial record preparation. The program was implemented using needs assessments through observation, structured material delivery, interactive discussions, hands-on transaction recording practice, and learning evaluations through pretests and posttests. The results show a significant improvement in participants’ competencies. Average scores for financial literacy and inclusion increased from 48% to 89%, indicating better understanding of cash flow management, transaction recording, and the use of digital financial services such as QRIS and mobile banking. Furthermore, participants’ understanding of capital access improved from 51% to 92%, particularly regarding financing procedures, business eligibility requirements, and the importance of financial statements in loan applications. Overall, the program effectively strengthened MSME capacity to manage businesses in a more structured, adaptive, and professional manner, supporting MSME independence and long-term business sustainability in Tatanga District and Nunu Village.

Communication is a fundamental element in the development of entrepreneurship, particularly within edupreneurship, which integrates educational innovation with entrepreneurial values to address contemporary challenges in education. In an increasingly competitive and digitally driven educational landscape, edupreneurs are required not only to possess pedagogical competence but also strong communication skills to sustain and scale their initiatives. This study aims to analyze the role of effective communication in strengthening edupreneurship competencies. The research employs a literature review method by synthesizing and analyzing relevant theories and previous studies on communication, entrepreneurship, and edupreneurship. The findings indicate that effective communication plays a significant role in enhancing key edupreneurship competencies, including negotiation skills, leadership capacity, personal branding, and adaptability to digital transformation. Communication also functions as a strategic tool for building trust, expanding professional networks, fostering collaboration, and creating supportive learning ecosystems within educational enterprises. Moreover, effective communication enables edupreneurs to articulate value propositions clearly, manage stakeholders efficiently, and respond flexibly to dynamic changes in educational markets. The implications of this study emphasize that communication competence is not a complementary skill but a core requirement for sustainable edupreneurship development. Therefore, systematic communication training and the integration of communication-based learning strategies are strongly recommended within entrepreneurship education programs, particularly for prospective edupreneurs, to support long-term innovation, competitiveness, and sustainability in the education sector.

The handling of children involved in narcotics crimes requires a restorative approach focused on rehabilitation rather than punishment. This study aims to examine the role of police investigators in applying restorative justice to child offenders in narcotics cases and to identify the obstacles encountered in its implementation. This research employs a normative legal research method with statutory and conceptual approaches. Primary legal materials include Law Number 11 of 2012 on the Juvenile Criminal Justice System, Law Number 35 of 2009 on Narcotics, and Chief of Police Regulation Number 8 of 2021. The findings show that investigators play a strategic role in facilitating diversion, including conducting initial assessments, facilitating diversion deliberations, and coordinating with supporting institutions such as the Correctional Center (Bapas), National Narcotics Agency (BNN), and Social Services. However, implementation remains suboptimal due to internal constraints, including inadequate training and understanding among investigators, limited facilities such as child-friendly rooms and mediation spaces, regulatory disharmony between the Juvenile Criminal Justice System Law and the Narcotics Law, weak inter-agency coordination, and lack of support from families and communities. Post-diversion monitoring is also ineffective. This study concludes that strengthening investigator capacity through specialized training, improving legal frameworks through regulatory harmonization, and enhancing inter-agency collaboration are essential to ensure restorative justice truly serves the best interests of children.

Children constitute a vulnerable group requiring protection from sexual crimes, including pedophilia. This research aims to examine criminal law provisions protecting child victims of pedophilia crimes in Indonesia and identify obstacles in their implementation. Using a normative juridical method with statutory and conceptual approaches, the findings demonstrate that legal protection is comprehensively regulated through the Criminal Code (KUHP), the Child Protection Law (Law Number 35 of 2014), Law Number 17 of 2016, and the Electronic Information and Transactions Law (ITE). These regulations provide a strong legal basis both in terms of principal criminal sanctions and additional sanctions such as chemical castration, electronic monitoring device installation, and perpetrator identity disclosure. The regulations also emphasize victims' rights to medical and psychological rehabilitation as well as identity protection. However, implementation faces several obstacles, including low case reporting rates due to stigma and taboo culture, evidentiary difficulties arising from victim trauma, weak inter-agency coordination, limited resources, and the emergence of digital pedophilia modi. Efforts to address these obstacles include strengthening law enforcement capacity, providing child-friendly justice systems, comprehensive rehabilitation services, public legal education, and synergy between government and non-government institutions in child protection.

Village-Owned Enterprises (BUMDes) are a strategic instrument in promoting village economic independence and increasing Village Original Income (PAD). However, in practice, BUMDes management still faces various governance issues, particularly related to human resource capacity, business innovation, and public accountability and trust. This study aims to analyze the acceleration of BUMDes governance from a Reinventing Government perspective through a comparative study between BUMDes in rural and urban areas. This study uses a qualitative method with a descriptive-comparative approach. Data collection techniques are carried out through in-depth interviews, observation, and documentation. The research locations include BUMDes in Paan Leleng Village, Kota Komba Utara District, East Manggarai Regency as a representative of rural villages, and BUMDes in Golo Bilas Village, Komodo District, West Manggarai Regency as a representative of urban villages. The research results indicate that the implementation of Reinventing Government principles in the governance of Village-Owned Enterprises (BUMDes) in both villages has been successful, but not yet optimal. The BUMDes in Golo Bilas Village has advantages in market access, business potential, and innovation, but still faces challenges in accountability and public trust. Meanwhile, the BUMDes in Paan Leleng Village demonstrates strong community participation and social values, but is hampered by limited human resources, technology, and business diversification. Accelerating BUMDes governance requires institutional strengthening, increased managerial capacity, business innovation, and the implementation of governance that is oriented towards results and community needs.

This research examines law enforcement against immigration violations and the factors influencing the effectiveness of border crossing inspection at the Immigration Checkpoint (TPI) of Tanjung Perak, Surabaya. Immigration inspection plays a vital role in safeguarding national sovereignty and monitoring cross-border human movement. Using a normative juridical approach with statutory and conceptual approaches, the findings demonstrate that enforcement procedures include document verification, identification of violations, administrative actions, and deportation in accordance with Law Number 6 of 2011 concerning Immigration. Common violations found include misuse of stay permits, travel document forgery, unauthorized border crossers, and illegal activities by foreign nationals beyond visa provisions. However, implementation still faces challenges such as limited human resources, inadequate infrastructure, and weak inter-agency coordination. Several factors affect the effectiveness of inspections, including personnel quality, technological support, legal frameworks, infrastructure capacity, traveler volume, inter-agency cooperation, political and international relations factors, socio-cultural dynamics, financial and logistical support, as well as internal supervision and accountability systems. The research concludes that institutional capacity building, policy integration, regulatory harmonization, and strengthened internal supervision are essential to ensure optimal immigration control at TPI Tanjung Perak in facing global challenges.

The purpose of this study is to analyze digital transformation in notary services, namely the validity of electronic deeds and the responsibilities of notaries in the era of e-government. This study uses a normative juridical method with a legislative and conceptual approach based on an analysis of relevant regulations, scientific literature, and other legal sources. Data was obtained through literature study and analyzed qualitatively and descriptively to assess the legal certainty and responsibility of notaries in preparing electronic deeds in the era of digital transformation in notarial practice. The results show that digital transformation in the notary field is an impact of information technology developments and e-government policies that change the notary's work processes, including administration, deed preparation, identity verification, and document storage. However, digitization must still comply with the principles of authenticity, legality, data security, and legal certainty in accordance with the characteristics of the notary's position as a public official. This study also found that the implementation of cyber notary in Indonesia still faces normative, technical, and ethical obstacles, such as the absence of comprehensive regulations, limited digital infrastructure, and the risk of identity abuse. Therefore, regulatory harmonization, capacity building for notaries, technology standardization, and effective supervision are needed so that the digitization of notary services can be implemented safely while maintaining the integrity of the profession.

Phishing constitutes a form of cybercrime that continues to proliferate alongside the rapid advancement of information technology, causing significant impacts on data security and financial losses. This study aims to analyse the forms of criminal liability applicable to phishing perpetrators under Indonesian criminal law and to identify the challenges and solutions in its enforcement. The research employs a normative juridical approach utilising literature review methodology. The findings demonstrate that criminal liability for phishing perpetrators can be established through provisions in the Electronic Information and Transactions Law (ITE Law) as amended by Law Number 1 of 2024, the Indonesian Penal Code (KUHP), and related regulations. However, law enforcement faces numerous obstacles, including inadequate specific legal regulations, limited digital forensic technology, low public legal literacy, and cross-border jurisdictional barriers. In judicial proceedings, evidentiary processes are frequently hindered by the complexity of electronic evidence and the limited technical understanding among law enforcement officers. This study recommends regulatory reform, capacity building for human resources, international cooperation, and public education to strengthen the effectiveness of law enforcement against phishing crimes.
