The transformation of public governance has encouraged a paradigm shift in public service delivery, from an administrative and procedure-oriented approach toward a citizen-centered and value-based model. In this context, public sector marketing has emerged as a strategic instrument to enhance service quality, institutional image, public participation, and trust. This study aims to examine the contemporary implementation of marketing strategies and planning in the public sector, with particular attention to their effectiveness and contextual relevance. The research adopts a qualitative descriptive approach through a systematic literature review of selected scholarly publications addressing public sector marketing, strategy implementation, digital governance, and public service management. The findings indicate that public institutions increasingly apply marketing principles not as commercial activities, but as mechanisms for creating public value through strategic communication, digital engagement, institutional branding, and stakeholder collaboration. However, the effectiveness of implementation varies across organizations and is strongly influenced by leadership capacity, human resources competence, organizational culture, and technological support. The study also reveals that public sector marketing strategies must be adapted to social, cultural, and institutional contexts, as private-sector models cannot be directly transferred. Theoretically, this study strengthens the positioning of marketing as an integral component of public governance. Practically, it provides insights for public organizations to develop contextual, responsive, and sustainable marketing strategies to improve public service performance and trust.

The increasing demand for infrastructure necessitates the construction of reliable bridges with long service lives to ensure smooth mobility. This research focuses on the Griya Lingga Permai Bridge over the Asam River in Jambi City, which is scheduled for widening as part of the Asam River Revitalization program aimed at flood mitigation. Although the project faces delays due to land acquisition constraints, this postponement is leveraged as a strategic opportunity to conduct a design review of the planned bridge superstructure.The bridge is designed using a reinforced concrete "T" beam girder structure. This study aims to perform a design review of the planned superstructure. This review includes the verification of calculations, structural dimensions, and a comparison of reinforcement calculation results, which are crucial for ensuring the future safety and reliability of the bridge against design loads. To support the validation and analysis process, the research utilizes STAAD.Pro software to obtain more accurate and detailed data regarding structural capacity. The results of this study will provide solid technical recommendations for the continuation of the construction project.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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 work of health workers is a key factor in ensuring the quality and sustainability of primary health services. However, high work demands and limited resources have the potential to weaken work involvement if they are not balanced with a perception of work meaning and adequate psychological capacity. This study aims to analyze the effect of job meaningfulness on work engagement of health workers through psychological capital as a mediating variable at the Mokoau Health Center, Kendari City, Southeast Sulawesi. This study used a quantitative approach with a cross-sectional design. All health workers at the Mokoau Health Center as many as 70 people were used as research samples using the total sampling method. Data was collected through a structured questionnaire and analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM) with the help of SmartPLS version 4.0. The results of the analysis showed that job meaningfulness had a positive and significant effect on psychological capital (β = 0.698; p < 0.05). Psychological capital was also shown to have a positive and significant effect on work engagement (β = 0.691; p < 0.05). Furthermore, job meaningfulness had a significant indirect effect on work engagement through psychological capital (β = 0.482; p < 0.05), which shows the mediating role of psychological capital in the relationship. Job meaningfulness not only contributes directly to strengthening psychological capital, but also indirectly increases work engagement of health workers. Psychological capital plays a role as the main psychological mechanism that translates the meaning of work into higher work attachment. These findings affirm the importance of a human resource management strategy that focuses on strengthening the meaning of work and psychological capital to increase the work involvement of health workers in primary health care facilities.

The right to health is a fundamental human right that remains inherent to prisoners. This study aims to examine the legal protection of prisoners' right to health care as regulated in Law Number 22 of 2022 on Corrections, as well as its implementation in correctional institutions. The research uses a normative juridical method with statutory and conceptual approaches. The findings show that Law Number 22 of 2022 formally guarantees prisoners' access to health services, including mental health care and special protection for vulnerable groups such as women, the elderly, and persons with disabilities. Key provisions in Articles 10, 11, 12, and 14 establish the state's obligation to provide adequate health services equivalent to community standards. However, in practice, the realization of this right faces several obstacles including: (1) overcapacity of correctional facilities exceeding 180% of ideal capacity, (2) limited medical personnel with many institutions lacking permanent doctors, (3) inadequate health facilities and medicine supplies, (4) complicated referral procedures causing delays in emergency treatment, and (5) insufficient budget allocation. Strengthening technical regulations, improving infrastructure, enhancing cross-sectoral collaboration, and implementing effective oversight mechanisms are essential to ensure effective protection of prisoners' health rights as mandated by the constitution and international human rights standards.

Drug abuse constitutes a serious threat to public health, social stability, and national security. This study examines law enforcement mechanisms against drug abuse under Indonesian Law Number 35 of 2009 on Narcotics and evaluates preventive measures implemented to combat this phenomenon. Employing a normative juridical approach through a comprehensive literature review, this research analyses the implementation of both penal and non-penal approaches in addressing narcotics-related offences. The findings reveal that law enforcement practices predominantly emphasise punitive measures, despite legislative provisions accommodating rehabilitation for drug users. The dual approach integrating criminal sanctions with social and health services remains suboptimal due to institutional constraints, limited rehabilitation facilities, inadequate training for law enforcement personnel, and weak inter-agency coordination. Preventive efforts through education, family empowerment, school-based programs, community engagement, and media campaigns have been implemented but continue to face challenges, including social stigma and insufficient public awareness. This study recommends strengthening restorative justice implementation, expanding rehabilitation service capacity, and enhancing cross-sectoral collaboration to build societal resilience against drug abuse while ensuring that users receive appropriate treatment rather than mere criminalisation.

Oral loan agreements remain a prevalent form of contract in Indonesian society, particularly within familial relationships, friendships, and informal financial transactions. This study aims to examine the legal standing of oral loan agreements under the Indonesian Civil Code (Kitab Undang-Undang Hukum Perdata/KUHPerdata) and to analyse the evidentiary mechanisms applicable in cases of default (wanprestasi). This research employs a normative juridical approach, utilising secondary data sources comprising legislation, legal doctrines, and relevant court decisions. The findings indicate that oral loan agreements are legally valid and binding provided they satisfy the requirements stipulated in Article 1320 of the Civil Code, namely mutual consent, legal capacity, a specific object, and a lawful cause. However, the fundamental weakness of such agreements lies in the evidentiary challenges that arise during dispute resolution. In the absence of written documentation, proof of the agreement's existence and content must rely on alternative forms of evidence, including witness testimony, acknowledgement by the parties, bank transfer records, receipts, electronic communications, and circumstantial evidence as recognised under Article 1866 of the Civil Code and the Electronic Information and Transactions Law. The success of claims in default cases largely depends on the strength, consistency, and relevance of the evidence presented. This study concludes that while oral agreements possess full legal force, parties are strongly advised to document loan transactions in writing or secure supporting evidence to ensure greater legal certainty and facilitate effective dispute resolution.
