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.

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.

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.

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 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.

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.

Flood disasters have repeatedly affected Aceh Tamiang Regency for over fifteen years, causing significant material and socio-cultural losses. This study aims to examine the social response of the community through a literature review approach, using Jurgen Habermas's Communicative Action Theory as the analytical framework. Data were collected systematically from national journal articles, scientific proceedings, and academic reports related to flood mitigation and community social response in Aceh Tamiang. Data analysis was conducted using content analysis and thematic analysis techniques. The findings reveal that the community's response is primarily driven by local solidarity rooted in cultural values and local wisdom such as hadih maja. In Habermasian terms, this social response reflects the lifeworld domain, manifesting in voluntary collective action. However, a structural tension exists between the government's top-down system and the community's communicative rationality. Effective disaster mitigation requires the development of participatory public spaces that bridge the system and lifeworld, enabling the transformation from instrumental action to communicative action, thereby strengthening collective resilience against flood disasters.

The problem of urban flooding is a growing issue due to high population density, increasing volumes of plastic waste, and the reduction of water absorption areas. The use of conventional paving blocks, which are impermeable, further exacerbates flooding conditions because they do not allow water to infiltrate into the soil. This study aims to develop an innovative plastic waste-based paving block incorporating rice straw and sugarcane bagasse, along with the integration of phytoremediation concepts as a solution for urban flood mitigation. The method employed was an experimental approach involving the following stages: material preparation, plastic incineration, material mixing, molding, and testing of water absorption capacity and compressive strength. The results showed that paving blocks with a combination of plastic waste, rice straw, and sugarcane bagasse had the highest water absorption rate of 34% and compressive strength of 21 kg/cm², meeting SNI standards. The addition of natural materials containing silica was proven to enhance the material’s porosity and strength. Additionally, the application of phytoremediation using water hyacinth has the potential to improve the quality of water seeping into the soil. Thus, this phytoremediation-based paving block innovation can serve as an effective alternative solution to reduce flood risks while supporting sustainable waste management and environmental stewardship.

Floods are the most frequent hydrometeorological disasters in Indonesia and significantly contribute to increased trauma cases and disruption of healthcare services, particularly in vulnerable regions such as Aceh Province. These conditions are exacerbated by limited resources, damaged health facilities, and restricted access to referral centers. This study aims to examine the implementation of early emergency surgical management during flood disasters based on damage control surgery principles and international guidelines. A descriptive qualitative approach was employed through a literature review combined with field observations conducted during the emergency response phase of flood disasters in Bireuen Regency. Data were collected from direct clinical observations, brief interviews with healthcare providers, and documentation of trauma cases requiring early surgical intervention. The results indicate that effective patient stabilization can be achieved despite limited resources through airway, breathing, and circulation (ABC) management, hemorrhage control, wound irrigation, and fracture immobilization using simple and improvised equipment. Approximately 90% of patients were successfully stabilized prior to referral to definitive healthcare facilities. In conclusion, adaptive and timely application of damage control surgery principles plays a crucial role in saving lives and strengthening emergency surgical response during flood disasters.

Urban development has resulted in an increase in impermeable surfaces, increasing the risk of runoff inundating the road network. This situation occurs in the drainage system on Jl. Letjend S. Parman, Jl. Emo Kurniaatmaja, and Jl. Pulau Banda, Pasirkareumbi Village, Subang Regency. This study aims to evaluate the hydraulic performance of existing channels and develop redesign guidelines to reduce the risk of local flooding. The methods used include hydrological analysis of daily maximum rainfall data from the Subang rainfall station, rainfall frequency analysis using the Generalized Extreme Value (GEV) distribution, Intensity-Duration-Frequency (IDF) curves, and hydrological and hydraulic simulations using the Storm Water Management Model (SWMM). Model parameters include sub catchment area, rainfall intensity, time of concentration, infiltration using the Curve Number method, channel dimensions, cross-sectional shape, channel material, and the Manning coefficient. The results indicate that the GEV distribution provides a good fit for determining design rainfall. Based on the typology of a metropolitan city and a catchment area of ​​26.04 ha, the modeling period is 2 to 5 years. The SWMM simulation results indicate that some channel segments have very high flow velocities, potentially causing scour, while other segments have very low velocities, potentially causing sedimentation. This confirms the need for evaluation and restructuring of channel dimensions and slopes to improve the hydraulic performance of road drainage and reduce localized flooding.

The objectives of the study are: 1) To analyze the level of vulnerability of agricultural land to flash floods in Nagari Pauh Kamang Mudiak, 2) To analyze the condition of agricultural land in Nagari Pauh Kamang Mudiak before and after the flash flood. The results of this study: 1) Analysis of the level of vulnerability of agricultural land to flash floods in Nagari Pauh Kamang Mudiak, namely in the safe class covering an area of 8.34 hectares, the non-vulnerable class covering an area of 12.01 hectares, the vulnerable class covering an area of 51.91 hectares and the very vulnerable class covering an area of 18.13 hectares. This shows that most of the research areas have a high level of vulnerability to flash floods. Furthermore, the analysis of flash flood risks with 4 risk classifications is an area with a low risk of 16.94 hectares, a moderate area of 30.60 hectares, a high area of 37.78 hectares, and a very high area of 5.07 hectares. Based on the results of this analysis, the agricultural land most affected by the flash flood in Nagari Pauh Kamang Mudiak is rice fields covering an area of 72.2 hectares, 2) Analysis of the condition of agricultural land vegetation in Nagari Pauh Kamang Mudiak before and after the flash flood, namely with 5 classes, namely the very low greenness class covering an area of 12.69 hectares, low covering an area of 29.69 hectares, medium covering an area of 13.22 hectares, and high covering an area of 34.84 hectares. The results of the accuracy test using overall accuracy reached a suitability of 89.58% and the kappa coefficient reached a suitability of 84.32%, meaning good accuracysuitability between the classification results and actual conditions in the field.

Floods are one of the most frequent hydrometeorological disasters in Indonesia and cause various social, economic, and environmental impacts on communities. In disaster situations, women often face greater vulnerability than men due to limited access to resources, high domestic responsibilities, and minimal protection in disaster policies. Although the government has adopted a gender mainstreaming policy in development, its implementation in disaster management policies remains suboptimal. This study aims to analyze how flood management policies integrate gender perspectives and identify the impacts of floods on women. The study used a qualitative approach using literature study methods and media content analysis to understand the dynamics of policies and women's experiences in disaster situations. The results show that disaster management policies still tend to focus on technical and infrastructure aspects, while women's specific needs are often overlooked, particularly regarding security in refugee camps, access to reproductive health services, and increased domestic burdens during crises. This condition indicates that the integration of a gender perspective in disaster policies still faces various structural and institutional barriers. Therefore, efforts are needed to strengthen the implementation of gender-responsive policies so that disaster management does not only focus on physical mitigation, but is also able to provide fairer and more inclusive protection for all community groups.

The flash flood disaster that hit Indonesia, including the devastating disaster in three Sumatran provinces in November-December 2025 which resulted in more than 900 casualties and trillions of rupiah in losses, shows a strong correlation between environmental damage caused by corporate activities and increased disaster risk. The purpose of this study is to analyze corporate criminal liability for environmental damage resulting in flash flood disasters based on the Environmental Management Law (UU PPLH), examine the mechanism for proving corporate criminal liability, and evaluate the application of criminal sanctions against corporations that commit environmental damage resulting in flash flood disasters. The research method used is normative legal research with a descriptive analytical statute approach. Data collection techniques are carried out through library research and interviews with sources at the North Sumatra Provincial Environmental Service. The data obtained were analyzed qualitatively. The results of the study indicate that: First, corporate criminal liability for environmental damage resulting in flash floods has been comprehensively regulated in Articles 116 to 120 of the Environmental Management and Management Law, which recognizes corporations as subjects of criminal law and regulates the criteria for corporate crimes (committed by, for, or on behalf of a business entity), the responsible party (the business entity and/or the person giving the order/leader of the activity), a one-third aggravation of the sentence, and corporate representation in court, as reinforced by Supreme Court Regulation Number 13 of 2016. The conclusion of this study is that the Environmental Management and Management Law has provided a comprehensive legal framework for corporate criminal liability for environmental damage resulting in flash floods. However, the effectiveness of law enforcement still needs to be improved through accelerating the judicial process, strengthening the capacity of law enforcement, improving inter-agency coordination, and strengthening the decision execution mechanism.

Semarang City is an urban area with a high vulnerability to flooding. Based on data from the Semarang City Regional Disaster Management Agency, in 2022 there were 133 flood events with extreme rainfall reaching 200 mm per day. Kota Lama Semarang is a historical tourist destination with high heritage value, but this area often faces flooding challenges, especially around the Tawang Polder Area with inundation reaching 30-100 cm. This condition is triggered by an existing drainage system that is not optimal due to limited channel capacity and blockages caused by sedimentation. The purpose of this study is to develop the SEMAR-SUDs smart drainage system innovation. The writing method was carried out through literature studies, hydrometeorological data reviews, and descriptive-quantitative analyses, which formed the basis for the design and implementation of the innovation. SEMAR-SUDs (Semarang-Sustainable Urban Drainage Systems) concept is an integrative solution that combines three main elements Debris Separate Baffle Boxes (DSBB) as a technology for separating waste and sediment, ArborFlow technology based on ecodrainage that optimizes rainwater retention and distribution and Self Closing Flood Barriers that work automatically to protect critical areas. The implementation of SEMAR-SUDs can be a solution model in increasing flood disaster resilience in the city of Semarang while supporting the realization of SDGs 9 (sustainable infrastructure development), SDGs 11 (resilient and sustainable cities), and SDGs 13 (climate action). The SEMAR-SUDs innovation is highly suitable for implementation in Semarang City to mitigate flooding and realize a smart, adaptive, and sustainable drainage system infrastructure.

This study looks at how the government isn't doing enough to watch over logging in Sumatra and how that leads to a higher chance of flooding, using the ideas from Administrative Law. Ineffective supervision, both during the licensing process and afterwards, significantly contributes to the decline of the forest's ecological functions, resulting in hydrological disasters. The study uses normative law and follows a literature review method. The data used consists of secondary data, including primary legal materials such as legislation, as well as secondary materials like textbooks, academic journals, and digital sources. Data was gathered by looking at documents and then looked at using a descriptive-qualitative approach. The research shows that the government's failure to properly carry out its responsibilities in forestry management can be considered an illegal government action, known as an 'onrechtmatige overheidsdaad'. This action goes against the General Principles of Good Governance (AUPB), especially the principles of being careful with public money, being responsible, and ensuring that laws are clear and followable. This situation leads to the government being responsible, which means they must take steps to fix the environment and offer help to the communities that were affected. This study suggests strengthening the forestry oversight system by implementing regulatory improvements, improving the capacity of officials, utilizing technology, and involving the community actively to ensure transparent, accountable, and sustainable environmental management.

Aceh Tamiang Regency is one of the regions in Aceh Province that is highly vulnerable to annual flooding due to river overflow and high rainfall intensity. Flood disasters often cause significant material and non-material losses, which are exacerbated by the limited public understanding of flood mitigation, early warning signs, and appropriate self-rescue procedures. This community service activity aims to increase public awareness, knowledge, and preparedness in facing flood threats through disaster mitigation socialization programs. The method applied in this activity includes participatory socialization, interactive discussions, and simulations of emergency response actions involving local communities, village officials, and volunteers. The program emphasizes recognizing early signs of flooding, understanding emergency evacuation routes, and improving coordination during disaster response. The results indicate a significant improvement in community knowledge regarding flood risks, early warning indicators, and emergency measures that should be taken before and during flooding events. Furthermore, the activity successfully strengthened coordination between village authorities and local volunteers in managing emergency response posts and distributing aid effectively. Through this socialization program, the community of Aceh Tamiang is expected to develop greater disaster resilience and preparedness. Increased awareness and coordinated response mechanisms are anticipated to minimize the adverse impacts of future flooding events, thereby reducing potential losses and enhancing community safety.

This study aims to analyze the strategic management of disaster services in handling flood-affected communities in Surabaya City. This study uses a qualitative descriptive approach with an analytical framework of strategic management theory according to Wheelen and Hunger (2008), which includes four main stages: environmental observation, strategy formulation, strategy implementation, and evaluation and control. Data were obtained through documentation studies, field observations, and secondary data searches from official reports from the Regional Disaster Management Agency (BPBD), the Central Statistics Agency (BPS), and relevant online sources. The results show that the BPBD of East Java Province has implemented a systematic strategic management cycle in disaster services. During the environmental observation stage, the BPBD was able to identify the main threat in the form of the dominance of hydrometeorological disasters, particularly floods. During the strategy formulation stage, the BPBD established a mission, objectives, and strategic policies focused on disaster risk reduction, increasing community preparedness, and strengthening cross-sectoral coordination. Strategy implementation is realized through mitigation, preparedness, and emergency response programs, as well as the utilization of early warning systems and command centers. Meanwhile, evaluation and control are carried out continuously through monitoring disaster events and adjusting policies based on actual conditions in the field. The flood-affected community management strategy demonstrates a responsive and collaborative approach, despite still facing structural challenges such as tidal flooding and limited drainage infrastructure. This study concludes that implementing strategic management based on the theory of Wheelen and Hunger (2008) can improve the effectiveness of disaster services, but requires strengthening long-term mitigation and community empowerment.

Flood disasters that struck Cikahuripan Village significantly affected the physical, psychological, and learning motivation conditions of elementary school students, particularly at SD N 1 Cikahuripan. In the post-disaster period, students experienced a decline in learning motivation caused by psychological trauma, loss of a sense of security, and limited learning facilities. This Community Service Program (Pengabdian kepada Masyarakat/PkM) aimed to restore students’ psychological conditions while strengthening their learning motivation through an integrated psychosocial and pedagogical approach. The implementation methods included an initial assessment of students’ conditions, trauma healing activities based on play therapy, and the application of Fun Learning methods combined with the “Tree of Dreams” activity to rebuild students’ intrinsic motivation. The program was conducted from 15 to 22 November 2025 and involved 31 elementary school students as well as teachers as sustainability partners. The evaluation results showed significant positive changes, indicated by increased cheerfulness, active participation, confidence in social interaction, and improved learning focus among students. In addition, teachers’ capacity to implement trauma-sensitive teaching practices also improved. This program demonstrates that post-disaster learning motivation recovery requires a holistic approach integrating psychological and academic recovery, and it has the potential to serve as a replicable model for educational interventions in disaster-prone areas.
