Beneath the surface: assessing pollution levels near major solid waste dumpsites in Lagos, Nigeria.

Effective solid waste management is a critical environmental challenge, particularly in rapidly growing Global South countries like Nigeria. This issue is exacerbated by burgeoning populations, lax waste regulations, and the widespread practice of open dumping. The deterioration of soil quality and alteration of water quality are major consequences of open waste dumping, posing significant environmental and public health risks. This study aims to assess the environmental risk and pollution status of soil and water resources near major dumpsites in Lagos. It aims to offer insights that can inform targeted interventions and policy measures not only in Lagos but also in comparable urban settings worldwide. Results indicated that important soil parameters, including TN (11.89-13.83mg/kg), pH (6.45-7.35), sulfate (36.71-39.49mg/kg), phosphate (9.31-14.39mg/kg), and electrical conductivity (342-566 µS/cm), were significantly affected by the dumpsites. Additionally, concentrations of heavy metals varied, with some exceeding permissible limits set by international standards, highlighting the environmental challenges posed by improper waste disposal in urban settings like Lagos. The analyzed parameters for water were mostly within acceptable limits, indicating a lesser impact of the waste dump on water resources. Water samples from boreholes and hand-dug wells near three dumpsites showed that pH, TDS, and heavy metal concentrations were mostly within WHO limits, with borehole water deemed safe for drinking and hand-dug wells suitable for cleaning. To alleviate the environmental impacts of open dumpsites, it is recommended to implement effective waste segregation, recycling programs, controlled landfilling, and investment in waste treatment technologies, along with regular water quality monitoring to prevent further pollution and protect public health. While these measures offer opportunities, they also face significant challenges due to financial and land constraints. Therefore, strong public awareness, infrastructure investment, and government commitment are essential, along with coordinated efforts among the government, private sector, and communities.

Employing deep learning in crisis management and decision making through prediction using time series data in Mosul Dam Northern Iraq

Specifically, Iraq is threatened in its second-largest northern city, Mosul, by the collapse of the Mosul Dam due to problems at the root of the dam, causing a wave of floods that will cause massive loss of life, resources, and public property. The objective of this study is to effectively monitor the level of dam water by predicting the level of water held by the dam In anticipation of achieving flood stage and breaking the dam, and supporting its behavior through formation 14-day time series data to predict seven days later. Used six deep learning models (deep neural network (DNN), convolutional neural network (CNN), convolutional neural network long short-term memory (CNN-LSTM), CNN-LSTM-Skip and CNN-LSTM Skip Attention) that models were trained to predict the water level in the dam; these levels of being under surveillance and prepared In case of danger, alert people to potential flood threats depending on the dam’s water level. These time series were created from the actual data sets of the dam; it’s a fundamental historical reading for 13 years (1993–2006) of the water level stored in the Mosul dam and was adopted in coordination with the Iraqi Ministry of Water Resources and the Centre for Research on Dams and Water Resources at Mosul University. The methodology applied in this study shows the model’s performance efficiency and the prediction results’ low error rate. It also compares those practical results to determine and adopt the performance-efficient model and a lower error rate. The comparison of these results proved the accuracy of its results, and superior to the CNN-LSTM model, it has the highest ability to perform through high accuracy with MAE = 0.087153 and time steps = 0 s 196 ms/step and loss = 0.00067. The current study demonstrated the ability to predict the water level in Mosul Dam, which suffers from foundation problems and may collapse in the future. Therefore, the water level in the dam must be monitored accurately. It also aims to test the effectiveness of the six models proposed in this study after evaluating their performance and applying the prediction process within a scenario to obtain predictive values after 14 days. The results showed the practical effectiveness of the hybrid CNN-LSTM model in correctly and accurately obtaining predictive values within the integrated framework of the required scenario. The study concluded that it is possible to enhance the ability to monitor and identify the potential risk of Mosul Dam at an early stage, and it also allows for proactive crisis management and sound decision-making, thus mitigating the adverse effects of crises on public safety and infrastructure and reducing human losses in areas along the Tigris River.

Building a Culture of Compliance: The Influence of Tax Socialization and Inclusion on Indonesian Micro, Small, and Medium Enterprises (MSMEs) Taxpayers

Taxes serve as the cornerstone of any nation's economic framework, functioning as both a regulatory mechanism and a primary source of government revenue. They are indispensable for managing taxpayer behavior, ensuring a steady stream of state income, and financing essential public services and infrastructure development. In Indonesia, the compliance of micro, small, and medium enterprises (MSMEs) is pivotal to the nation's fiscal well-being. This study delves into the factors that influence MSME taxpayer compliance, specifically focusing on the role of tax socialization, tax inclusion, and the involvement of tax volunteers. A quantitative research approach was adopted, involving the distribution of questionnaires to MSME taxpayers in Indonesia. The data collected was then analyzed using SPSS software to test the hypotheses regarding the impact of tax socialization, tax inclusion, and tax volunteers on taxpayer compliance. The findings of this study reveal that tax socialization and tax inclusion positively influence the level of tax compliance among Indonesian MSME taxpayers. Furthermore, the involvement of tax volunteers also has a positive impact on enhancing taxpayer compliance. This study underscores the importance of tax socialization and tax inclusion in fostering a culture of compliance among MSMEs in Indonesia. The positive role of tax volunteers in assisting taxpayers and promoting compliance is also highlighted. These findings have significant implications for tax authorities in their efforts to improve tax compliance rates and enhance revenue collection.

Sustainable Environmental Management: Evaluating the Effects of the Tail Number Restriction Policy on Air Quality in Lanzhou, China

In recent years, haze pollution in China has garnered significant attention from both the government and the public, with vehicle emissions being identified as a key source of pollution. This study analyzes the impact of the tail number restriction policy (TNRP) on air quality using daily data from Lanzhou, China, in 2020, by employing the regression discontinuity in time (RDiT) method. The results show that the TNRP significantly reduced the air quality index (AQI) and concentrations of PM2.5, PM10, NO2, and CO, indicating a positive effect on air quality, though this is not a long-term standalone solution. Unlike previous policies, the current TNRP restricts traffic during peak hours, yielding consistent effects. This study recommends continuing the restriction policy and developing a comprehensive environmental governance system to promote new energy vehicles and enhance public transportation infrastructure.

Accessible Infrastructure Development for the Visually Impaired

This paper focuses on daily struggles of visually impaired individuals with public infrastructure and services. Although it is now a cliche on making progress globally in disability rights, the reality on the ground is different. Infrastructure supporting independent mobility and social inclusion for the blind are often far from providing such aids and considerations, something that makes them navigate through a world whose design does not reflect the needs of the visually impaired people. The study brings out the critical issues of scarcity of tactile paving, inadequacy of braille signage, and complete absence of audible traffic signals, each of which is a grim reminder of how systematic these individuals are left out from being part of society. These are the physical barriers, but much more is beyond this. This research proposes practical solutions that can develop more inclusive standards, integrate innovative technologies, and overcome social and financial hurdles. By raising these issues, the paper seeks to contribute important ideas for policymakers, urban planners, and advocacy groups to truly motivate the collective action needed to make public spaces fully and widely accessible. The findings underscore the need for shared responsibility in infrastructure improvement, which will significantly enhance the quality of life for the blind and help reach society’s goals of being fairer and more inclusive.

How Does Politics Affect Quality of Public Transport Infrastructure?

While prior studies have investigated the impacts of political factors such as the ideological stance on quality of public infrastructure, there is a paucity of research on the political effects of re-election success, party fragmentation (political power), and the formation of new electoral consistency on quality of public transport infrastructure, which is represented in this paper by road maintenance efficiency. We employ an instrumental variable approach to mitigate a potential reverse causality bias inherent in literature. Our empirical results show that local governments whose political representatives were re-elected give rise to lower road maintenance efficiency. Local governments with new electoral constituencies report a higher road maintenance efficiency.

A Comprehensive Review of MI-HFE and IPHFE Cryptosystems: Advances in Internal Perturbations for Post-Quantum Security

The RSA cryptosystem has been a cornerstone of modern public key infrastructure; however, recent advancements in quantum computing and theoretical mathematics pose significant risks to its security. The advent of fully operational quantum computers could enable the execution of Shor’s algorithm, which efficiently factors large integers and undermines the security of RSA and other cryptographic systems reliant on discrete logarithms. While Grover’s algorithm presents a comparatively lesser threat to symmetric encryption, it still accelerates key search processes, creating potential vulnerabilities. In light of these challenges, there has been an intensified focus on developing quantum-resistant cryptography. Current research is exploring cryptographic techniques based on error-correcting codes, lattice structures, and multivariate public key systems, all of which leverage the complexity of NP-hard problems, such as solving multivariate quadratic equations, to ensure security in a post-quantum landscape. This paper reviews the latest advancements in quantum-resistant encryption methods, with particular attention to the development of robust trapdoor functions. It also provides a detailed analysis of prominent multivariate cryptosystems, including the Matsumoto–Imai, Oil and Vinegar, and Polly Cracker schemes, alongside recent progress in lattice-based systems such as Kyber and Crystals-DILITHIUM, which are currently under evaluation by NIST for potential standardization. As the capabilities of quantum computing continue to expand, the need for innovative cryptographic solutions to secure digital communications becomes increasingly critical.

2.M. Scientific session: Economics of Mental Health in the interplay between health systems and public health

Abstract Mental health systems and services are essential components of the public health infrastructure, serving as frontline for prevention and intervention for health overall. Despite this, access to mental health services remains largely inadequate, with the OECD calculating that only about one in three people with mental health problems has access to quality treatment across 19 EU Member States. The economics of mental health play an important role in determining the allocation of resources, the accessibility of services and the overall effectiveness of interventions. Effective planning requires an understanding of population needs, service gaps and utilization patterns, in order to ensure equity and health improvement. In fact, the conceptualisation of the economic dimensions of mental health enables policymakers, practitioners, and stakeholders to make informed decisions that optimize resource utilization and maximize societal benefits. The proposed workshop will build on previous activities of the EUPHA Section on Public Health Economics at EPH, including the recent establishment of a working group on the economics of mental health. The aim of the meeting is to promote the adoption of best practices and methodologies in the conduct of economic studies on mental health. As such, the workshop will provide an opportunity to discuss the unique challenges of economic evaluation in this field and to present relevant ongoing activities by members of the Section and other invited experts. Key messages • Mental health, its distribution and at-risk populations influence resource allocation and policy decisions within mental health systems. • Tackling inequalities in mental health is essential for promoting health equity and social justice, requiring evidence-based interventions and policy initiatives to empower marginalized communities.

Future actions and a call for ongoing support

Abstract The EUVABECO project is currently piloting a suite of innovative tools, including decision support systems, targeted screening tools, electronic vaccine leaflets, disease simulators, and cross-border vaccination cards. These tools have shown great promise in transforming vaccination practices within individual healthcare settings, contributing to building vaccine confidence and increasing protection against vaccine-preventable infections across the life course. As EUVABECO progresses to the crucial phase of implementing these pilots, active collaboration and sustained support from the multiple actors of the vaccine ecosystem in the implementing countries are essential. To ensure these tools are effectively adapted across different MS, they must be customised to meet local needs and the specific requirements of diverse healthcare environments. This involves integrating feedback from initial deployments. More than just a technical implementation, this phase is about fostering and maintaining robust partnerships with key stakeholders such as healthcare providers, policymakers, and National Immunization Technical Advisory Groups (NITAGs). The success of the EUVABECO project depends on continuous engagement and the sharing of knowledge and resources among all partners involved. This presentation seeks to reinforce the call for ongoing commitment and collaboration from existing stakeholders and to encourage new partners to join this transformative effort. This will foster a more harmonized approach to vaccination policies. Together, we aim to build a more resilient public health infrastructure, enhancing the preparedness and responsiveness to current and future vaccination challenges, ultimately improving resilience to health threats across the European Union.

Development of an Index System for Public Toilets Based on HRWS-PS Theory and Improvement Strategies

As an integral part of the urban public health infrastructure, public toilets play a significant role in shaping a city’s image. With the advancement of the economy, people have increasingly higher expectations for public toilets. While existing standards primarily focus on physical indicators, there is still room to incorporate measures that prioritize humanistic care. Therefore, based on the Human Rights to Water and Sanitation in Public Spaces (HRWS-PS) standards, this study develops a comprehensive index system for public toilets with a specific emphasis on humanistic care, utilizing expert questionnaires and employing methods such as the analytic hierarchy process (AHP) and entropy weight, and highlights safety and quality as paramount concerns for users, followed by usability and accessibility as secondary needs. Acceptability, which encompasses additional amenities, depends on meeting these secondary needs through solid basic design and construction practices. Affordability, related to consumer costs, is comparatively less demanding. By applying this framework, an analysis of the current state of upgrading urban public toilets in Shijiazhuang was conducted, leading to recommendations for improvements across four key areas: environmental sanitation, architectural design, infrastructure development, and urban planning. The final results provide practical insights for evaluating and suggesting enhancements to ongoing toilet revolution initiatives and urban basic service facilities while also informing urban renewal efforts and designs.

Institutional Discrimination in Health Security Policies against Immigrants in South Korea

Abstract Background South Korea is poised to become Asia’s first mult-iethnic society with over 5% of its population, totaling more than 2.5 million, being immigrants. This demographic shift presents significant public health challenges linked to widespread, and even intensifying, institutional discrimination in healthcare services. Methods This study reviews discriminatory practices across ten essential health security programs, including National Health Insurance (NHI) system, disability assistance, occupational health services, maternal and child care services, national immunization program, health screening program, and assistance for catastrophic medical expenses. Government data and personal narratives were also reviewed to identify the discriminatory elements that can have significant consequences, including increased disease prevalence, higher incidence of occupational injuries, and broader socio-economic instability among migrants. Results Discriminatory elements were found in most programs, with the exception of emergency medical services. These programs commonly provide fewer benefits or impose stricter eligibility criteria for migrants compared to nationals. In particular, the Korean NHI system demands migrants to pay higher premiums and more rigorous maintenance requirements. Conclusions The findings emphasize the need for urgent reforms to equalize health insurance costs, simplify eligibility criteria for migrants, and broaden the scope of benefits to encompass all residency statuses. Implementing these changes will enhance public health infrastructure, improve occupational safety, and foster better integration of the diverse population, ultimately promoting social cohesion and a fairer health system for all. Key messages • A number of discriminatory elements against migrants have been identified in South Korea’s social security policies that can exacerbate health disparities. • Reforms are needed to expand benefits and relax eligibility criteria for migrants in key healthcare policies, including the National Health Insurance system.

Global health

Abstract Global health emphasizes the importance of addressing health challenges that transcend national borders and require strong international collaboration and governance. This concept is grounded in collaborative transnational actions aimed at promoting health for all, reducing disparities, and protecting against threats. Strengthening health systems, public health infrastructure, improving health service delivery, and ensuring equal access to healthcare for all are key focus areas in global health. This plenary will address several major health challenges and critical issues, such as the rising burden of non-communicable diseases, re-emerging pandemics, environmental threats, and the suboptimal responses of national healthcare systems to manage these challenges. The need to focus on vulnerable and marginalized populations, particularly those affected by migration and ethnicity, will be highlighted. The discussion will also showcase the importance of including ethnic minority and Indigenous people’s perspectives in health policy and decision-making processes, as well as addressing the social determinants of health that disproportionately affect these communities. Central to the discussion on global health is the role of global health policy and diplomacy, focusing on how countries can collaborate to address health threats and challenges, shaping international strategies and frameworks. Innovation, including reverse innovation and the development of evidence-informed policies and effective public health strategies that can be implemented globally and is relevant also in resource-constrained contexts, is another critical aspect in addressing the intersection of health and development. Finally, strong public health leadership is needed to shape practices and policies, as well as fostering the next generation of global health leaders. The multifaceted nature of global health calls for a comprehensive approach to health—one that integrates policy, leadership, and equity into the core of public health strategies. The integration of health into all policies at the global level is vital for creating supportive environments, policies, services, and communications that promote better health for all.

Public–private partnerships and human development

Abstract The restructuring of a state is crucial for promoting human development. For this reason, public–private partnerships (PPPs), the so-called “fourth revolution” in reinventing the state, have become a global strategy of choice. Yet, existing studies on PPPs mainly analyze their effect on growth or inequality, not human development. This article uses data from the human development index (HDI) database to investigate the impact of PPP projects on human development. With the increasing scale of public infrastructure investments and the need to improve public services, it is necessary to examine whether PPPs are justified in improving social welfare. We conducted the analysis for all low- and middle-income countries using propensity score matching (PSM) and multivariate analysis. Additionally, we present the HDI predictions. We believe that assessing the impact of public–private cooperation on increasing social welfare, reducing social exclusion, and implementing investments with a robust social impact is essential. Overall, we found a statistically significant effect of PPPs on human development, demonstrating that the growing scale of PPP investments in low- and middle-income countries enhances their HDI.

Characteristics of Diseases in Developing Countries

In the urgent realm of global health, it is imperative to acknowledge and promptly address the distinct characteristics of diseases that afflict developing countries. These nations face a unique set of challenges that contribute to the burden of illness and significantly impact the quality of life for their populations. By promptly exploring the key features of diseases in developing countries, we can better understand the complex interplay between socioeconomic factors and health outcomes [1]. One of the primary characteristics of diseases in developing countries is their disproportionate impact on vulnerable populations. Socio-economic disparities, limited access to healthcare, inadequate sanitation infrastructure, and poor nutrition contribute to the heightened susceptibility of marginalized communities to preventable infectious diseases such as hydatid cysts, malaria, tuberculosis, and diarrheal illnesses. The lack of resources and infrastructure further exacerbates the spread of these diseases, creating a cycle of sickness and poverty [2,3]. Furthermore, the prevalence of neglected tropical diseases (NTDs) is a defining feature of the disease landscape in developing countries. These illnesses, which include dengue fever, Chagas disease, and schistosomiasis, predominantly affect populations in low-resource settings and often go unnoticed on the global health agenda. The burden of NTDs is compounded by limited funding for research and treatment, leaving affected communities without adequate support and interventions [4]. In addition to infectious diseases, non-communicable diseases (NCDs) are on the rise in developing countries, posing a dual burden of illness alongside contagious diseases. Factors such as urbanization, lifestyle changes, and an aging population contribute to the increasing prevalence of conditions like cardiovascular diseases, diabetes, and cancer. The inadequate healthcare infrastructure in many developing countries further hinders NCDs' prevention, diagnosis, and management, leading to poorer health outcomes for those affected [5]. Addressing the characteristics of diseases in developing countries requires a multi-faceted approach that encompasses strengthening the healthcare system, investing in public health infrastructure, and, most importantly, providing equitable access to essential medicines. By ensuring fair access to these medicines, we can work towards achieving health equity and reducing the burden of disease in developing countries.

Unlocking public infrastructures? State aid and the common European data space

EU state aid rules are part of the EU’s competition policy, a form of soft law developed to nudge states away from public investments in many areas. Rules were used to impose that market competition holds a privileged position, and that enacting social, political, or economic benefits that might stifle competition requires a complicated legal and political negotiation process between the European Commission, Member States, and private companies. Nonetheless, many strategic projects or situations in recent years led to significant state aid. The Commission utilised a variety of means to encourage both private and public investments in EU based digital infrastructure that is critical for public media services and for unified European data space. Despite EU’s balancing act between the private and public interests, business interests are dangerously capturing the development in the media data space. To grasp the social and economic contribution of publicly financed productive activities, we approach public broadcasting systems as producers of public wealth of a peculiar kind whose activities and goals are defined by their public purpose, rather than the imperatives of capital and profitmaking. Unifying data spaces with too many design decisions conceded to capitalist production runs the risk of further neglecting social foundations of member states. We argue that the desired digital transformation would be more successful if it moved towards affirmative approaches to public services and public infrastructures, recognising the historical and contemporary contribution of the production of public wealth and public media in member states.

A Stochastic Approach to the Power Requirements of the Electric Vehicle Charging Infrastructure: The Case of Spain

Battery electric vehicles represent a technological pathway for reducing carbon emissions in personal road transport. However, for the widespread adoption of this type of vehicle, the user experience should be similar to that of combustion engine vehicles. To achieve this objective, a robust and reliable public charging infrastructure is essential. In Spain, the electric recharging infrastructure is growing quickly in metropolitan areas but much more slowly on roads and highways. The upcoming charging stations must be located along high-volume traffic corridors and in proximity to the Trans-European Transport Network. The main contribution of this research is to offer a method for examining the essential electricity infrastructure investments required in scenarios involving substantial electric vehicle adoption. The methodology includes a sensitivity analysis of fleet composition and market share, recharging user behavior, charging station density, and vehicle efficiency improvements. To this end, the authors have developed a simplified probabilistic model, addressing the effect of the involved parameters through a comprehensive scenario analysis. The results show that the actual number of high-capacity charging plugs on Spanish roads is significantly lower than the European regulation requirements for the year 2030 considering an electric vehicle market share according to the Spanish Integrated National Energy and Climate Plan 2021–2030 objectives and it is far from the necessary infrastructure to cover the expected demand according to the traffic flow. Under these circumstances, the charging peak power demand reaches over 7.4% of the current Spanish total power demand for an electric vehicle fleet, which corresponds to only 12% of the total.

Policy interventions and urban characteristics in modeling electric vehicle charging infrastructure utilization

The surge in electric vehicles adoption necessitates understanding the impact of policy interventions on public electric vehicle charging infrastructure in urban areas. This research investigates the influence of pricing frameworks on the usage of public charging facilities by analyzing both behavioral and spatial attributes of these infrastructures. Utilizing open data from Palo Alto, United States, this study employs descriptive statistical methods and interpretable machine learning approaches to scrutinize the relationship between policy initiatives and charging behaviors. The analysis underscores the significance of spatial attributes on charging behaviors. Policy interventions yield noticeable alterations in charging metrics, with locations near commercial hubs showing higher utilization, while local and frequent users resist fee adjustments. The research emphasizes the necessity for customized strategies to optimize infrastructure development and management, offering a framework for policymakers and stakeholders in sustainable urban transportation. Future research should explore similar interventions in diverse urban settings using real-time data and advanced optimization techniques to better tailor policies to the unique characteristics of specific facilities.

The 2024 Public Health Emergency of International Concern: A Global Failure to Control Mpox.

On August 14, 2024, following a regional declaration by the Africa Centres for Disease Control and Prevention, the World Health Organization declared mpox a Public Health Emergency of International Concern, marking the second such declaration in two years. A series of outbreaks involving the more virulent clade I virus (compared to clade II, which caused a global outbreak in 2022), has now spread in 13 African countries, exposing the inadequacies of the public health infrastructure in these settings. There was significant investment during the 2022 global outbreak, but these efforts failed to address vaccine access and treatment in the Global South. Regulatory delays, unequal access to vaccines, and a lack of compassionate use treatments for severe cases have resulted in preventable cases and deaths, especially among vulnerable populations such as pregnant women, children, and the immunocompromised. The current outbreak also underscores critical knowledge gaps in our understanding of mpox, including its transmission, pathogenesis, and viral evolution. We join intensified calls for global solidarity and action to control mpox, emphasizing immediate containment measures and long-term local and international investment in African public health systems, to prevent future epidemics.

Measurement methods and influencing factors of carbon emissions from residents' travel

Residents' travel is a significant source of transport carbon emissions. Revealing the mechanisms behind travel-related carbon emissions can assist transportation departments in developing effective emission reduction policies. However, current research often focuses on specific aspects such as measurement accuracy or the impact of certain factors, lacking a comprehensive review and discussion. This study addresses the research gap by conducting a systematic literature review on measurement methods and influencing factors of carbon emissions from residents' travel. Through evaluating each method's applicability and limitations, we establish a systematic framework for measuring carbon emissions from residents' travel. By selecting appropriate measurement methods, detailed quantitative analysis of influencing factors is enabled, providing crucial data for subsequent emission reduction strategies. Influencing factors are categorized into four groups, including public infrastructure, road traffic facilities, land use and population, and traveler's socio-economic attributes, with a total of nine sub-factors across these categories. The relationship between each factor and carbon emissions is examined through statistical and qualitative analyses, establishing a robust quantitative analysis methodology for future research. Finally, a roadmap for reducing carbon emissions in residents' travel is presented.

Application of the Public-Private Partnership Concept in Airport Development in Bintan Regency to Enhance the Coastal Economy

The efforts of various regions to introduce the identity and beauty of their areas are often hindered by inadequate infrastructure and poor management by local governments. Additionally, funding, which is critical for development, poses a significant challenge. As a solution, Public-Private Partnerships (PPP) offer an alternative approach to budgeting and financing that extends beyond the use of regional (APBD) and national (APBN) budgets. In Bintan Regency, various infrastructure developments aimed at supporting the tourism sector have been undertaken. Notably, PT. Angkasa Pura II, in collaboration with PT. Bintan Aviation Investments, is committed to constructing an international airport designed with Airport Resort Facilities, named Bintan New Airport or Busung Airport, to bolster the economy of Bintan Regency. However, the study reveals that the development, which is anticipated to become a cornerstone of economic strength in Bintan Regency, faces significant challenges from the Airport Business Entity (BUBU). This has resulted in delays and complications in the continuation of the airport construction project between PT. Angkasa Pura II and PT. Bintan Aviation Investments. Despite these obstacles, the partnership remains focused on achieving its goal of enhancing the regional economy through improved infrastructure and tourism facilities. he collaboration between PT. Angkasa Pura II and PT. Bintan Aviation Investments represents a strategic move to leverage private sector efficiency and innovation in public infrastructure projects. Nonetheless, the ongoing challenges with the Airport Business Entity highlight the complexities involved in such partnerships, necessitating careful management and oversight to ensure project continuity and success.
