Acute Respiratory Infection (ARI) remains a major public health problem in Indonesia. Based on the 2025 National Health Reporting System survey, ARI ranked first among diseases with the highest number of cases, reaching more than 14.5 million cases. This study aimed to determine and analyze the relationship between environmental sanitation and nutritional status with the incidence of ARI among children under five following flood disasters in the working area of Panteraja Community Health Center, Pidie Jaya Regency. The study employed a quantitative method with an analytical observational design using a case-control approach. The dependent variable was the incidence of ARI among under-five children, while the independent variables were environmental sanitation and nutritional status. The sample consisted of 122 children under five, including 61 children with ARI and 61 children without ARI. The results of the chi-square test showed a significant relationship between environmental sanitation and ARI incidence (p = 0.000; OR = 0.042; 95% CI = 0.014–0.133), as well as between nutritional status and ARI incidence (p = 0.000; OR = 0.011; 95% CI = 0.001–0.083). These findings indicate that poor environmental sanitation and inadequate nutritional status contribute to the occurrence of ARI among children under five after flooding. Therefore, promotive and preventive efforts, along with regular monitoring of children's nutritional status, are essential to reduce the risk of ARI.

Environmental pollution is a common problem in cities and can increase the likelihood of flooding. The purpose of this study is to analyze environmental pollution as a cause of flooding in the Pekapuran Street area, Depok City. This study applies a descriptive method with a qualitative approach. Data were obtained through observation, documentation, and literature review. Based on the results of the study, it was found that the accumulation of household waste around the drainage channels causes obstruction of water flow, which triggers flooding during rain. In addition, the shallow, mud-filled, and poorly maintained drainage conditions increase the risk of flooding. Low levels of public awareness of environmental cleanliness are also factors that exacerbate the condition. This study concludes that flooding on Pekapuran Street is influenced not only by high rainfall, but also by environmental pollution and a suboptimal drainage system. Based on this, better waste management and drainage maintenance are needed to minimize the risk of flooding in the area.

Flooding remains a recurrent hazard in the Special Capital Region of Jakarta (DKI Jakarta), causing substantial disruptions across multiple dimensions community life, including social well-being and economic activities. The availability of flood-related information through the Jakarta One Data Portal (Satu Data Jakarta) provides significant opportunities for broader data utilization; however, transforming such information into meaningful assessments regional vulnerability requires a systematic analytical approach to generate more comprehensive understanding of the conditions of individual urban villages (kelurahan). This study focuses on the classification areas based on the characteristics and impacts of flood events occurring throughout DKI Jakarta. The analysis utilizes flood event records from 2023 to 2025 and incorporates several indicators, including the number of flood occurrences, the number of affected neighborhood associations (RW), the number affected households, the number of affected residents, the number of evacuees, the number of evacuation sites, and floodwater depth. Data processing was conducted using the Knowledge Discovery in Databases (KDD) framework, encompassing data selection, cleaning and preprocessing, transformation, pattern exploration, result evaluation, and knowledge extraction. The findings demonstrate that three-cluster solution effectively captures variations in flood vulnerability levels, corresponding to low-, moderate-, and high-risk categories. A total of 96 urban villages were classified as low-risk, 27 as moderate-risk, and 46 as high-risk areas. The resulting clustering patterns provide a clearer spatial representation of flood-risk distribution across urban villages, thereby offering valuable insights for the development more targeted mitigation strategies, the prioritization of flood management interventions, and the enhancement of evidence-based decision-making processes in DKI Jakarta.

Background:Flooding is one of the most common environmental problems in residential areas and is closely related to poor community awareness of waste management. Improper waste disposal can clog drainage systems, increase the risk of flooding, and lead to various environmental health problems. Objective: This community service activity aimed to improve community knowledge and awareness regarding waste management and environmental health as an effort to prevent flooding in Panompuan Jae Village. Methods: The activity was conducted on May 22, 2026, at the Panompuan Jae Village Prayer House involving 15 women from a local religious study group. The educational methods included lectures, discussions, and interactive question-and-answer sessions. The materials covered waste classification, household waste management, environmental health, and the relationship between environmental cleanliness and flooding. Results: The activity improved participants’ understanding of proper waste management. Participants were able to distinguish between organic and inorganic waste and understood appropriate waste handling practices. They actively participated in the discussion and showed an initial commitment to disposing of waste properly and maintaining environmental cleanliness. Conclusion: The community education program successfully improved public knowledge and awareness regarding waste management and environmental health, supporting flood prevention efforts in Panompuan Jae Village.

Land-use changes dominated by impervious surfaces in residential areas reduce the natural infiltration capacity of the soil and increase surface runoff, which may lead to flooding and waterlogging. This study aimed to design a rainwater infiltration well system as an effort to reduce surface runoff in Samudera Afroza 3 Housing Estate, Jambi City. A quantitative approach was employed through field surveys, hydrological analysis, soil permeability testing, GIS-based land-use analysis, and infiltration well design in accordance with SNI 8456:2017 and SNI 03-2453-2002 standards. Rainfall analysis was conducted using maximum daily rainfall data from 2014–2023, applying several probability distributions, with the Gumbel distribution identified as the most representative model. The results revealed that the residential area covers 8,104 m², with 91.84% of the land occupied by built-up surfaces, resulting in limited natural infiltration capacity. The average soil permeability value of 0.00024 m/s indicates favorable conditions for the implementation of infiltration wells. Based on the design calculations, 41 Type III infiltration wells are required, providing a total storage capacity of 289.665 m³ and an infiltration discharge of 0.0919 m³/s. The proposed infiltration well system is capable of reducing runoff volumes by 15.044%, 12.486%, and 11.223% for 2-year, 5-year, and 10-year return periods, respectively. Therefore, infiltration wells can be considered an effective alternative for water conservation and runoff management in residential areas.

Background: Pargarutan Julu Village, East Angkola District, South Tapanuli does not yet have a waste disposal site (TPS), causing residents to habitually dump waste into rivers and burn it around residential areas. In addition, the lack of knowledge about natural disaster mitigation is a problem that needs to be addressed urgently. Objective: This community service activity aims to increase public knowledge and awareness through education on waste management (sorting organic and inorganic waste, impacts of river pollution, and the 3R principle: Reduce, Reuse, Recycle) and natural disaster preparedness (floods and fires). Methods: The activity was conducted outdoors in the village at night using lecture, PowerPoint presentation, and interactive discussion methods, involving 35 participants consisting of children and village residents of Pargarutan Julu. Results: The activity showed high enthusiasm from participants, with many questions raised during the interactive discussion sessions. There was an increase in community understanding of the importance of waste sorting, the dangers of dumping waste into rivers, the application of the 3R principle, and steps for preparedness against flood and fire disasters. Conclusion: The participatory outdoor educational approach effectively improved knowledge and awareness of Pargarutan Julu Village residents regarding proper waste management and natural disaster preparedness, and encouraged sustainable behavioral change in the community.

The drainage system is critical infrastructure for managing stormwater runoff in densely built urban areas, including higher education institutions. This study aims to evaluate the capacity performance of the existing drainage channels in the UPN "Veteran" Jawa Timur campus area. The evaluation was conducted through two main stages: hydrological analysis using the rational method to estimate the design runoff discharge for a 10-year return period, and hydraulic analysis using Manning's equation to calculate the channel cross-sectional capacity in accordance with Permen PU No. 12 of 2014. Based on the assessment of 43 drainage channels, the results showed that 33 channels (76.7%) are still functioning optimally and capable of accommodating the design discharge. Conversely, 10 channels (23.3%) were identified as having insufficient capacity. This capacity deficit was triggered by initial designs that did not accommodate the 10-year return period flood discharge, increased runoff coefficients due to massive pavement development, and effective cross-section narrowing caused by sedimentation. To mitigate inundation issues, this study recommends redesigning the failing channels using an economical hydraulic cross-section, accompanied by periodic normalization and dredging for functional channels. The findings of this study are expected to serve as technical guidelines for the optimal and sustainable management of campus drainage infrastructure.

Online maps applications have become an essential tool for modern society in finding the fastest and most efficient routes. However, these applications often fail to detect current road conditions such as flooding, demonstrations, accidents, or public events, causing users to get stuck in problematic routes. This study aims to develop a prototype of a community-based road condition reporting system, visualized through a web-based digital map. The system allows users to directly report road conditions by providing photo evidence, descriptions, and event categories. It is also equipped with features for designing event routes such as carnivals and suggesting alternative paths based on community reports. The development process was carried out using a simulation-based approach with scenario testing that reflects real field conditions, without involving direct user data. The implementation results show that all core features work properly. The technologies used include Leaflet.js, OpenStreetMap, and the Nominatim geolocation API. This research produces an adaptive community-based GIS model that can be further developed as an intelligent navigation solution at the city scale

Rapid population growth in Sidoarjo Regency has triggered massive land-use changes, resulting in increased surface runoff and reduced performance of the drainage system. This study aims to evaluate the hydraulic capacity of drainage channels in the Pondok Sidokare Indah Housing area against design flood discharges with return periods of 2, 5, and 10 years. The method used is a descriptive quantitative approach, involving hydrological analysis using maximum daily rainfall data from 2015–2025 and hydraulic modeling of the existing channel along 350 meters. The frequency analysis results indicate that the Log Pearson Type III distribution is the most suitable method based on statistical parameters and the Smirnov-Kolmogorov goodness-of-fit test. The calculation of design flood discharge using the rational method yields values of 0.749 m³/s (2-year), 1.003 m³/s (5-year), and 1.164 m³/s (10-year). Meanwhile, the maximum capacity of the existing channel ranges only between 0.534 m³/s and 0.733 m³/s. The comparison between hydrological load and channel capacity shows that all observation points (Sta 0+000 to Sta 0+350) are in overflow condition, even for the lowest return period flood discharge. This condition confirms that the current channel dimensions are no longer adequate and require normalization to mitigate annual flooding in the area.

Various floods in Jayapura City in early 2025 have caused a number of losses. The problem of the impact of this flood can be solved by reducing the occurrence of flooding again, especially in the long term through the formation of children's character who care about the environment. Activities to increase environmental awareness were carried out by planting flowers focused on children studying at the Rumbel Pelita located at Kali Sunyi, Polda Bhayangkara Public Housing Complex, Buper Waena. The purpose of this community service activity was to increase children's awareness of the surrounding environment through flower planting. The problem posed was how to change children's behavior to care about the environment to prevent flooding. The solution was to increase children's awareness through flower planting at the Kali Sunyi location, Polda Bhayangkara, Buper Waena, Heram District. The method used was through counseling, question and answer sessions, and flower planting activities accompanied by their care. This care was carried out primarily during the learning process at the Rumbel that took place in the future after the community service activity. The results of this community service have been carried out by planting approximately 165 flowers at the Rumbel location, planted by 50 children.

This article analyzes the recurring flash floods in North Konawe Regency which occurred in 2000, 2013, 2016, 2018, 2019, 2020, and 2021 as ecological disasters causally linked to three decades of natural resource exploitation through logging, oil palm plantations, and open-pit nickel mining. Using the dual framework of political ecology and environmental justice, this article argues that these disasters are not neutral natural events, but rather the product of a structured system of injustice: the indigenous Culambacu People and Tolaki People communities who were excluded from decision-making processes regarding extractive permits have borne the greatest burden of the destructive impacts of such exploitation. The most dramatic event was the 2019 flood that devastated Tapuwatu Village, causing losses amounting to Rp 674.8 billion and displacing 9,908 people. The findings demonstrate that the dominant government narrative framing the floods as “natural disasters caused by high rainfall” constitutes a strategic denial that obscures structural responsibility. Empirical data including rates of deforestation, exceeded river carrying capacity, and the chronology of concession expansion correlated with disaster escalation support the ecological disaster thesis. Persistent poverty amid abundant natural resource wealth confirms the condition of a “sacrifice zone,” characterized simultaneously by distributive, recognitional, and procedural injustices.

This study aims to examine flood disaster mitigation efforts carried out by the Regional Disaster Management Agency in Sukamakmur Village, Karawang Regency. This research employed a qualitative method with a case study approach. The theory used in this study is the Strategy Theory proposed by James Brian Quinn (2003:10), which consists of three dimensions: objectives, policies, and programs. The study identifies problems related to flood disasters that occur almost every year in Sukamakmur Village. To address these issues, it is necessary to analyze the mitigation efforts implemented by the Regional Disaster Management Agency (BPBD), as well as the related policies and programs concerning flood disasters. The findings show that the objective of disaster mitigation is directed toward improving community preparedness and capacity in dealing with flood risks. Mitigation policies are implemented through strengthening community capacity based on non-structural mitigation, such as the establishment of Disaster Resilient Villages (DESTANA), village disaster volunteers, and disaster risk assessments. The mitigation programs carried out include disaster awareness socialization, mitigation training, and dissemination of daily weather information. In its implementation, BPBD also coordinates with the village government, sub-district task forces, and the River Basin Management Agency (BBWS). These mitigation programs have had a positive impact on increasing community knowledge, preparedness, and participation, although there are still obstacles in the form of limited budgets, infrastructure, human resources, and suboptimal cross-sector coordination. The contribution of this research is to provide additional insight and new information regarding the role of the Regional Disaster Management Agency in flood disaster mitigation.

Flooding is one of the most common hydrometeorological disasters that significantly affects community life and governmental administration. Post-disaster management requires the involvement of multiple stakeholders through a collaborative approach to accelerate rehabilitation and reconstruction efforts. This study aims to analyze the humanitarian mission carried out by cadets of the Institute of Public Administration (IPDN) in post-flood management in Aceh Tamiang Regency using the Collaborative Governance framework developed by Ansell and Gash (2008). The study employs a qualitative approach with a case study method. Data were collected through document analysis, including activity reports, photographic documentation, official publications from the Ministry of Home Affairs, IPDN, local governments, and other supporting documents. Data analysis was conducted through coding, categorizing, and thematizing processes, which were subsequently interpreted based on the dimensions of Collaborative Governance. The findings indicate that the involvement of IPDN cadets represents an effective practice of collaborative governance. In the starting conditions dimension, collaboration was driven by the urgent need for rehabilitation and the limited resources available to the local government. The facilitative leadership dimension was reflected in the roles of the Ministry of Home Affairs, local governments, and the Regional Disaster Management Agency (BPBD) in facilitating coordination among stakeholders. Furthermore, institutional design was manifested through clear task allocation and coordination mechanisms, while the collaborative process was characterized by dialogue, trust, commitment, and shared understanding in supporting post-disaster recovery.

The urgency of this research lies in the increasing risk of flooding and air pollution in Makassar City due to rapid urbanisation and the uncontrolled growth of motorised vehicles. The purpose of this study is to analyse the potential of urban planning and sustainable mobility policies in reducing disaster risks and environmental impacts, and to formulate more adaptive and data-driven policy strategies. This study uses qualitative methods by collecting data through interviews, documentation, observation, and focus group discussions (FGDs). Key informants include the Environmental Agency, the Spatial Planning Agency, and the Makassar Regional Disaster Management Agency (BPBD), which have strategic roles in spatial planning policies, environmental management, and disaster mitigation. The study findings indicate that flood risk and air pollution in Makassar City are complex problems influenced by population growth, land conversion, vehicle density, limited drainage, climate change, and industrial waste. Although various urban planning policies have been implemented, their effectiveness remains limited due to implementation constraints. Therefore, an integrated approach that combines adaptive urban planning, environmentally friendly mobility, effective waste management, and community participation is needed. With a systemic and coordinated strategy, Makassar has the potential to reduce flood risk, reduce pollution, and create a safer, healthier, and more sustainable urban environment.

Flooding is one of the most frequent disasters in DKI Jakarta and contributes not only to physical and economic losses but also to the emergence of various psychological problems among affected communities. This study aims to analyze the psychological impacts of post-flood disasters, particularly among vulnerable groups such as children and the elderly, and to examine the effects of repeated flood exposure on mental health conditions. This study employs a literature review method with a qualitative descriptive approach through the identification and synthesis of relevant scientific sources. Data analysis was conducted using content analysis to identify patterns, relationships, and trends in research findings. The results indicate that flooding is associated with psychological disorders such as stress, anxiety, depression, and post-traumatic stress disorder (PTSD), with varying levels of severity. Repeated exposure to flooding has been shown to increase individuals’ vulnerability to mental health problems and reduce psychological well-being. However, protective factors such as social support, religiosity, emotional regulation abilities, and adaptive coping strategies play a significant role in strengthening resilience and accelerating psychological recovery. The findings highlight the importance of a holistic disaster management approach that integrates mental health services, strengthens community capacity, and enhances preparedness education to improve the psychological resilience of flood-affected communities.

The Aceh Tamiang region was one of the areas affected by the hydrometeorological disaster. The disaster not only caused damage to community facilities and infrastructure but also left behind dead soil deposits that were poor in nutrients, dense in texture, and less productive for supporting agricultural and plantation activities. Research was conducted to examine strategies for utilizing dead soil after flooding by processing it with organic materials so that it could be converted into organic fertilizer with utility and economic value. This research aimed to find environmentally friendly land rehabilitation solutions, increase soil productivity, and open new business opportunities for disaster-affected communities. The results showed that the combination of flood sediment soil with organic materials significantly increased nutrient content, improved soil structure, increased water holding capacity, and accelerated the growth of test plants compared to untreated soil. Furthermore, this program provides dual benefits: on the one hand, it serves as a post-disaster land rehabilitation solution, and on the other hand, it serves as an opportunity for an organic fertilizer business that can reduce the community's dependence on relatively expensive chemical fertilizers. The implications of this research are not only limited to the technical aspects of agriculture but also touch on the socio-economic dimensions of the community. Utilizing dead soil as organic fertilizer can strengthen local economic resilience, increase farmer independence, and encourage the creation of environmentally friendly, sustainable agricultural systems. Therefore, this strategy can serve as an innovative model for addressing the impacts of hydrometeorological disasters in other areas facing similar challenges.

The flash floods that struck Aceh Tamiang caused infrastructure damage and contaminated clean water sources, making it difficult for residents to obtain potable water. This situation increases the risk of water-borne diseases and worsens the post-disaster situation. This research aims to develop a large-scale, simple water filtration prototype as an emergency response solution that is effective, economical, and easy to implement by affected communities. The methods used include field observation, water sampling, testing simple physical parameters (turbidity, color, odor, and pH), and designing a gravity-based, multi-stage filtration system without electricity. The prototype uses a combination of filter media such as gravel, silica sand, activated charcoal, and natural fibers in a drum system. Test results show a decrease in turbidity levels from 150–300 NTU to 5–15 NTU after the filtration process, as well as an increase in pH to near neutral. The filtered water is declared suitable for sanitation and consumption after undergoing a further disinfection process. In addition to implementing the technology, this research also includes public education regarding the selection of safe water sources and maintenance of the filtration system. Based on these results, this large-scale simple water filtration prototype is effective as an appropriate technological solution in handling the post-disaster clean water crisis and has the potential to be replicated in other flood-prone areas.

This article analyzes the legal status of golf course development, specifically Gunung Geulis Country Club (GGCC) in the Puncak-Bogor Area within Indonesia's spatial planning policy and Green Open Space (RTH) protection framework, while evaluating its ecological impacts from an environmental justice perspective. Employing a normative juridical method with statutory, conceptual, and case-based approaches, this research identifies two core issues. First, golf course development occupies a legal grey area: it is recognized as private RTH under Article 29(2) of Law No. 26 of 2007 on Spatial Planning, yet substantively fails to fulfill the ecological functions mandated by law due to its exclusivity and inaccessibility to the public. Second, from an environmental justice perspective, GGCC's development generates layered distributive, procedural, and corrective injustices: surrounding communities bear the burden of groundwater contamination, reduced spring discharge, increased surface runoff, and flood risk, while economic and recreational benefits are concentrated among a small number of high-fee members. Weak AMDAL instruments, minimal public participation, and inconsistent spatial monitoring in the Puncak-Bogor protected area exacerbate these conditions. This article recommends policy reforms including stricter private RTH definitions, strengthened participatory AMDAL processes, and consistent application of the polluter-pays principle.

This study analyzes the urgency of strengthening citizen lawsuit mechanisms in response to spatial planning failures from an environmental law perspective, using the 2025 floods in Bali as a case study. The study is motivated by the increasing frequency and intensity of floods, which can no longer be understood as merely natural phenomena, but rather as the result of structural failures in spatial planning management and weak government accountability. Normatively, spatial planning is regulated under Undang Undang Nomor 26 Tahun 2007 dan Undang Undang Nomor 32 Tahun 2009 however, its implementation reveals a gap between legal norms and actual practice. The methodology employed is a normative legal approach, involving an analysis of legislation, legal doctrine, and judicial practices related to citizen lawsuits. The study's findings show that land-use conversion and development in water catchment areas, which go against the precautionary principle, the polluter pays principle, and sustainable development, are examples of spatial planning violations that cause flooding in Bali. In this situation, citizen lawsuits increase public access to justice while acting as a legal tool to hold the state responsible for its carelessness. However, this mechanism's effectiveness is still limited by the absence of a clear legal foundation, the difficulty of the burden of proof, and the public's limited access to the litigation process. Therefore, in order for citizen lawsuits to serve as effective tools for environmental protection and accountability, it is imperative that clear regulations be established, procedures be streamlined, and public access and ability information be improved.

Flooding in Aceh has become a recurring phenomenon that cannot be understood solely as a natural disaster but also as a result of human activities within modern society. This study aims to analyze flooding in Aceh through the perspective of Ulrich Beck’s risk society theory, focusing on how modernization, environmental change, and development policies contribute to the production of risk. This research uses a literature review approach by examining scientific articles published between 2021 and 2026 from indexed national and international journals. The analysis was conducted thematically to identify patterns, similarities, and research gaps. The findings show that natural factors such as high rainfall and atmospheric conditions act as primary triggers, while human activities including land-use change, river sedimentation, and ineffective policies significantly intensify flood risks. Flooding is therefore categorized as a manufactured risk produced by modern development processes. In addition, the impacts are not limited to ecological damage but also affect social and psychological conditions of society. These results indicate that floods should be understood not only from a technical perspective but also from a social perspective. The study implies that flood management requires a comprehensive approach integrating environmental sustainability, social awareness, and evidence-based policy to reduce both the impact and sources of risk in a sustainable manner.
