This study examines the implementation of Indonesia’s Visa on Arrival (VoA) policy in DKI Jakarta as both an instrument of tourism-driven economic recovery and a component of non-military national defense management under Law No. 23 of 2019 on the Management of National Resources for National Defense. While VoA has significantly contributed to the rebound of international tourist arrivals—surpassing 11 million visits nationally in 2023—it simultaneously generates governance challenges at strategic entry points such as Soekarno–Hatta International Airport, where facilitation of mobility intersects with risks including overstaying, transnational crime, human trafficking, and potential infiltration by non-state actors. Existing scholarship largely emphasizes economic impacts and regulatory frameworks, leaving limited analysis of VoA as part of an integrated civil defense infrastructure. Addressing this gap, the study aims to analyze how VoA implementation in DKI Jakarta is managed within a non-military defense perspective, particularly regarding institutional coordination, immigration intelligence, and risk mitigation mechanisms. Employing a qualitative case study approach, data were collected through in-depth interviews with immigration officials and security stakeholders, document analysis of relevant laws and ministerial regulations, and review of official immigration statistics, followed by thematic analysis. The findings indicate that although VoA effectively supports economic and diplomatic objectives, its function as a non-military defense instrument remains constrained by fragmented inter-agency coordination, uneven intelligence integration, and limited adaptive governance capacity at the local level. Strengthening collaborative surveillance systems, data-sharing mechanisms, and strategic policy alignment between immigration authorities and national defense institutions is therefore essential. The study concludes that reframing immigration governance as part of Indonesia’s broader non-military defense strategy is crucial to balancing openness with security in high-density international gateways.

Household plastic waste remains a serious challenge in urban environments, including Jl. Assofa II, Kebon Jeruk, West Jakarta, which is characterized by high population density and intense socio-economic activities. The low level of public awareness in sorting and managing plastic waste, particularly bottle caps, highlights the need for educational approaches from an early age. This community service activity aimed to enhance environmental awareness, creativity, and character development among children through the “Recycled Keychain” project, which involved recycling plastic bottle caps into keychains. The activity was implemented using a Project-Based Learning (PjBL) approach and involved 12 children aged 7–9 years as the main participants. The implementation methods included education on waste management based on the principles of reduce, reuse, and recycle (3R), collection and sorting of bottle caps, and the process of creating creative products. The results showed an increase in children’s environmental awareness and environmentally responsible behavior, the creation of eco-friendly educational products, as well as improvements in creativity, motor skills, and teamwork abilities. In addition, this activity supported the strengthening of the Pancasila Student Profile, particularly in the dimensions of cooperation, critical thinking, creativity, and independence. Overall, the Recycled Keychain project proved to be an effective model of contextual, participatory, and sustainable environmental education in instilling environmental care values from an early age in urban communities.

Population density plays a critical role in shaping public health outcomes and environmental quality, particularly in rapidly urbanizing regions. This study aims to analyze the relationship between high population density and its impacts on sanitation conditions, air quality, access to clean water, and the incidence of various diseases in densely populated areas. The research adopts a qualitative descriptive approach by combining a comprehensive literature review with field observations conducted in several urban areas characterized by high population concentration. The findings reveal that increased population density is closely associated with environmental degradation, including inadequate sanitation systems, reduced air quality due to pollution, and limited availability of clean water. These environmental challenges contribute directly to a higher prevalence of health problems, such as respiratory infections, waterborne diseases, and other communicable illnesses. Overcrowded living conditions also intensify the spread of diseases, placing additional pressure on public health infrastructure. Furthermore, the study highlights that insufficient public facilities and poor environmental management exacerbate the negative effects of population density on both health and the environment. To address these challenges, effective strategies are required, including population growth control, improved urban planning, and enhanced investment in public health and environmental sanitation facilities. Strengthening community awareness and participation in maintaining environmental cleanliness is also essential. Overall, this study emphasizes the need for integrated policies that balance population management with sustainable environmental and public health development.  

This study aims to analyze the development and scientific relationship between carbon risk perception, behavioral compliance of accountants, and sustainability mindset on the accuracy of carbon performance reporting through a bibliometric approach. This study is driven by the increasing need for accurate carbon reporting amidst global demands for sustainability transparency, as well as the limited understanding of the role of behavioral and psychological factors of accountants in ensuring the reliability of carbon reports. Research data was obtained from two leading scientific databases, namely Scopus and Google Scholar, with the main keywords "carbon risk perception," "behavioral compliance of accountants," "sustainability mindset," and "accuracy of carbon performance reporting." The data selection process was carried out using the PRISMA method to ensure the relevance and validity of the analyzed articles, while bibliometric analysis and visualization were performed using VOSviewer software. The results of the study indicate that the topic related to carbon reporting accuracy has evolved from a technical approach to a behavioral and psychological approach. Network and density visualizations show that behavioral compliance and sus-tainability mindset issues are still new but have high potential for development. Meanwhile, the authors' collaboration map demonstrates the geographic limitations of research, which remains concentrated in developed countries. These findings have important theoretical and practical implications, namely the need to integrate behavioral theory and professional ethics into sustainability accounting research and to en-hance accountants' capacity to understand carbon risks to ensure the accuracy of future sustainability re-porting.

The rapid development and population growth in Bekasi Regency, Indonesia, have resulted in increasing traffic density and a corresponding rise in road traffic accidents (RTA), particularly along the critical 28 km Kalimalang Inspection Highway, locally known as "Jalur Tengkorak." This study aims to analyze the simultaneous and partial influence of Vehicle Factors (X1), Human Factors (X2), and Road Physical Condition Factors (X3) on RTA (Y). A quantitative descriptive approach utilizing Multiple Linear Regression (MLR) was employed, based on primary data collected through questionnaires from 100 motorcycle riders and secondary data from Polresta Bekasi (2022). The findings confirm that all three variables significantly and positively influence RTA, resulting in the model \hat{Y} = 2.218 + 0.302 X1 + 0.161 X2 + 0.289 X3 + \mu. The adjusted coefficient of determination (R^2) is 0.514, indicating that 51.4\% of RTA variation is explained by these factors. Crucially, the Road Physical Condition Factor (X3) emerged as the strongest predictor (t=4.429, \beta=0.385), surpassing the traditional dominance of human error. This key finding suggests that mitigation strategies must prioritize urgent infrastructure repair addressing potholes, road waves, and insufficient markings to significantly reduce accident frequency in this corridor.

This study provides valuable insights into the development of more adaptive, multidisciplinary environmental auditing strategies that align with sustainable development goals.

The rapid population growth and urbanization in Jakarta have led to various urban challenges, one of the most significant being traffic congestion, which incurs substantial economic losses. One proposed solution is the development of Transit Oriented Development (TOD) areas, particularly through the expansion of mass transit infrastructure such as the Mass Rapid Transit (MRT) system. This study examines the potential for TOD development in the planned East–West MRT Corridor, with a case study focused on the Grogol MRT Station. This area is considered strategically significant due to its integration with multiple transportation modes, including TransJakarta, microtrans services, and a Type B bus terminal. This research employs a quantitative approach, utilizing both primary and secondary data. The assessment is conducted using a TOD Index method based on three core principles: density, diversity, and design. The analysis reveals that the Grogol MRT Station area has a population density of 19,953 people/km² and a building density of 2,741 units/km², both of which meet the criteria for an urban-scale TOD. The land use entropy index is 0.63, indicating a moderate level of land-use diversity. However, the availability of pedestrian paths (33.96%), bicycle lanes (1.67%), parking facilities (1.84%), and open green space (1.79%) remains significantly below the ideal TOD standards. Overall, the TOD Index score for this area is 0.417, placing it among the bottom five MRT stations in Jakarta. Despite this, the area fulfills the density requirements for urban TOD classification. Nevertheless, challenges remain, including insufficient pedestrian and bicycle infrastructure, limited green spaces, and low land-use diversity. Planning interventions are thus necessary, focusing on the provision of integrated pedestrian and cycling infrastructure, functional public spaces, and mixed-use zoning to promote sustainable urban mobility.

Osteoporosis is a metabolic bone disorder characterized by a decrease in bone density and strength, making bones more fragile and susceptible to fractures. People with osteoporosis often complain of pain. One of the pain management methods for osteoporosis patients is progressive muscle relaxation. This community service activity empowers the public to practice progressive muscle relaxation techniques. The pre-test results showed that the majority of the community’s knowledge about osteoporosis and pain management was in the poor category, at 79.5%. After education and simulation of the progressive muscle relaxation technique were conducted, there was an increase in the community’s knowledge about osteoporosis and pain management, with 61.4% in the good category. The conclusion of this community service activity is that empowering the community to independently perform progressive muscle relaxation techniques is very beneficial in reducing pain in people with osteoporosis.

This research is motivated by the importance of education as a basic right of the nation's children that continues to experience innovation, including in the school model based on boarding school. The focus of the research is social studies learning at MTs Darul Hikmah Tulungagung which implements the boarding system. The purpose of this study was to determine teacher strategies, implementation, and obstacles in social studies learning in this environment. The study used a qualitative approach with a case study type, and data was collected through observation, interviews, and documentation. The results of the study showed that the effectiveness of social studies learning was influenced by the density of institutional activities, lack of mastery of the material by teachers, and dualism of the curriculum. Efforts made include improving teacher discipline, utilizing audio-visual media, and linking material to current issues. The advantages of the boarding school system are that students become more independent, have high social awareness, and obtain general and religious education in a balanced manner. This finding implies the need for improvements in learning strategies and time management so that the boarding school system can run more optimally in supporting the achievement of social studies learning.

This study aims to analyze the dynamic relationship between population density, Gross Regional Domestic Product (GRDP) per capita, and regional economic inequality in Indonesia over the period 1995–2024. Regional inequality is measured using the Gini Ratio as a key indicator. A quantitative method with a time series approach is employed using the Vector Autoregression (VAR) model. The analysis includes unit root testing, optimal lag selection, VAR estimation, impulse response function (IRF), variance decomposition, and Granger causality testing. The results show that population density has a positive effect on regional inequality, while GRDP per capita has a negative effect. However, both variables are statistically insignificant. The impulse response analysis indicates that a shock in population density tends to increase inequality in the short term, whereas a shock in GRDP per capita tends to reduce inequality. The Granger causality test reveals that population density regional inequality, while GRDP per capita does not have a significant causal effect. Overall, the findings suggest the importance of equitable economic development and population control policies in reducing regional disparities in Indonesia.

Hypercholesterolemia is one of the health problems that is often experienced by the elderly and has a major impact on their quality of life, especially because it increases the risk of cardiovascular diseases such as coronary heart disease, stroke, and peripheral vascular disorders. This condition often does not show symptoms, but the process of atherosclerosis can develop slowly and cause serious complications if not treated early. The Community Service Program (PKM) implemented at Panti Werdha Hana aims to increase awareness among the elderly of the importance of early detection of Cholesterol and High Density Lipoprotein (HDL) levels as part of efforts to prevent heart disease. This activity applies the Plan-Do-Check-Act (PDCA) approach, including total cholesterol and HDL examinations using the Point-of-Care Testing (POCT) method, as well as interactive education about risk factors and healthy lifestyles. The results of the activity showed that out of 76 participants, 38 people (50%) had total cholesterol levels above normal, while 22 people (28.95%) had low or very low HDL levels. Early detection through screening has proven effective in identifying cardiovascular risks earlier and providing a basis for timely medical and educational interventions. Through this activity, it is hoped that the elderly can understand their health conditions better and take preventive steps to maintain lipid levels within normal limits, to improve the quality of life and reduce the risk of cardiovascular complications in the future.

As business complexity and global competition intensify, the limitations of traditional cost accounting systems in providing relevant information for strategic decision-making become increasingly apparent. This has driven the adoption of Activity-Based Costing (ABC) and subsequently Activity-Based Management (ABM), which have evolved as vital tools to accurately allocate costs based on activities and transform this information into value-enhancing and efficiency-improving strategies. This study aims to map the landscape, influence, and visibility of ABC and ABM publications through a comprehensive bibliometric analysis using VOSviewer. The research method involves a Systematic Literature Review (SLR) for data collection and screening from 488 publications (2023-2025) indexed in Scopus from Google Scholar, followed by data analysis and visualization of co-authorship and keyword co-occurrence networks. The analysis results show the dominance of core concepts such as "activity-based costing/management," "activity," "costing," and "management" as the foundation of research. Identified thematic clusters include the basic applications of ABC and its impact on performance, managerial aspects of ABM, efficiency, and the challenges and benefits of implementation. Temporal trends indicate a shift in the focus of recent research towards the strategic and managerial contributions of ABM/ABC in enhancing efficiency, supporting decision-making, and driving organizational performance. Density visualizations confirm research "hotspots" in these areas, while also highlighting potential research gaps for the future. The conclusion demonstrates the continuous relevance of ABC and ABM as adaptive cost and performance management tools, as well as the evolution of the discipline continually adapting to modern business's strategic needs, guiding researchers and practitioners for further exploration.
