This study explores the practice of participatory communication and creative production implemented by the Anggrek Waste Bank along the Ciliwung River as an educational strategy for flood disaster mitigation. The research aims to understand how community-based waste management initiatives can serve as platforms for environmental learning and social empowerment. Using a qualitative approach with a case study method, this study investigates social dynamics, interaction patterns, and meanings constructed by residents through collaborative waste management and creative production activities. Data were collected through observation, in-depth interviews, and documentation. The findings reveal that participatory communication is manifested not only in formal education, counseling, or campaigns, but also in everyday interactions, creative workshops, and collective community work. Creative products such as recycled crafts, soap made from used cooking oil, and eco enzymes function as symbolic communication media that persuasively convey ecological messages while providing tangible economic benefits. These practices foster a sense of ecological responsibility, strengthen social solidarity, and enhance community resilience to flooding. This study concludes that participatory communication integrated with creative production serves as an effective model for promoting sustainable behavior and community-based flood mitigation in urban environments.

Nabire Regency, located in Central Papua Province, is among the regions highly vulnerable to flooding due to persistent and intense rainfall throughout the year. Flood disasters generate multifaceted impacts, including economic losses caused by property damage and business disruptions, social issues such as health problems and psychological distress, and environmental degradation in the form of erosion and water pollution. This study aims to formulate mitigation and adaptation strategies for flood disasters by analyzing community perceptions and evaluating existing measures. The research employs the Likert Scale method to assess public perception and the Analytic Hierarchy Process (AHP) approach to determine the most effective strategies for mitigation and adaptation. The findings reveal that the community possesses a solid understanding of flood events and acknowledges the necessity of implementing mitigation and adaptation efforts. The AHP analysis indicates that the Regional Disaster Management Agency (BPBD) plays a crucial role in executing flood management strategies, particularly within the environmental management domain. The primary recommended strategy is environmental planning and management. Through an integrated and sustainable approach, flood risks are expected to be mitigated more effectively, minimizing adverse impacts on both the community and the environment in Nabire Regency.

Krisis ekologis di Kalimantan Barat, seperti banjir tahunan, deforestasi, dan pencemaran sungai, menuntut keterlibatan berbagai pihak, termasuk mahasiswa Katolik. Gereja Katolik melalui ajaran ekologi integral menegaskan bahwa tanggung jawab ekologis adalah bagian dari iman. Penelitian ini bertujuan untuk menggambarkan tingkat pengetahuan, kesadaran, gaya hidup, dan refleksi iman mahasiswa Katolik terhadap isu lingkungan. Menggunakan pendekatan kuantitatif deskriptif, data dikumpulkan dari 34 responden melalui angket daring dan dianalisis secara statistik deskriptif. Hasil menunjukkan bahwa mayoritas responden memiliki kesadaran ekologis awal dan bersedia terlibat dalam aksi lingkungan, namun belum sepenuhnya konsisten dalam praktik gaya hidup ramah lingkungan. Hanya sebagian kecil yang menerapkan kebiasaan konkret seperti membawa tempat makan sendiri. Temuan ini menunjukkan adanya kesenjangan antara kesadaran dan tindakan, serta perlunya strategi pembinaan iman yang mengintegrasikan spiritualitas dan praktik ekologis. Penelitian ini menjadi dasar awal untuk pengembangan program ekopastoral yang kontekstual di lingkungan kampus dan komunitas kategorial.

This community service initiative aims to apply biopore infiltration hole technology as a community-based flood mitigation solution in Labuhan Ratu District, Bandar Lampung City. This area faces major problems in the form of a high risk of waterlogging caused by low soil absorption, predominance of watertight surfaces, and suboptimal drainage systems. The program is carried out with a project-based community empowerment approach, where as many as 50 local residents are involved in each stage of the activity. These stages include environmental awareness campaigns, technical training on making biopore infiltration holes, providing equipment, and direct practice in the field. A total of 100 strategic points in the Dasawisma Palapa 6 environment are the locations for the implementation of biopores. The results of the activity show that this simple technology effectively improves the soil's ability to absorb water and reduce surface runoff, so that the risk of inundation can be reduced. In addition, this activity also encourages the formation of community groups that are tasked with maintaining biopores, in order to ensure the sustainability of long-term benefits. This program not only has a positive impact on the quality of the physical environment, but also strengthens the capacity of citizens to manage natural resources based on appropriate technology. The active participation of the community has proven to be the key to success, as it creates a sense of belonging while increasing ecological awareness at the local level. These findings confirm that the integration of simple technological innovations and community empowerment is an effective strategy in building sustainable environmental solutions, especially in the face of urban flood challenges.

Floods are the most frequent natural disasters and cause material and non-material losses. One of the problems faced is the lack of early warning when floods occur. This problem can be overcome with a flood early warning system. This paper discusses the solution to this problem, namely by designing and implementing a real-time flood early warning system using IoT-based Internet of Things (IoT) technology ESP32 MQTT and APK Kodular. The objective of this research, compared to previous studies, shows a gap in the methods used. While previous studies used an IoT-based flood warning system that sends data via SMS or an HTTP server, this study applies real-time monitoring with the MQTT protocol, which allows sending water level data with low latency to the Kodular application for faster and more responsive warnings. The method used is to connect hardware with IoT where ESP32 is a client that sends data to MQTT and will display it in the Kodular APK. This flood early warning system consists of: ultrasonic sensors, ESP32, MQTT cloud, OLED, buzzer, LED, and APK on the phone to receive notifications through a mobile application created using Kodular. This IoT-based system is installed in the Kudu Regency river and can monitor water levels in real-time. Based on a predetermined threshold, the system can activate the LED indicator or buzzer and send an early warning message to the user via the APK on the phone. Test results show that this system functions effectively in providing flood warnings with an accuracy of 1-2 cm and in a timely manner, making it suitable for community-based flood monitoring solutions

Floods are one of the most common natural disasters and have a significant impact on the social, economic, and environmental aspects of society. This is particularly evident in the community of East Sorong District. East Sorong District is one of the areas frequently affected by floods, and this inevitably leads to numerous risks and consequences. There are several causes of flooding in the Sorong Timur District, including extreme rainfall, inadequate drainage systems due to trash blockages, uncontrolled land use changes resulting in overpopulation, and the loss of forest areas or green spaces that could function as water absorption zones. Additionally, the lack of flood control systems and weak oversight of development in flood-prone areas can exacerbate flood disaster risks. This study aims to analyze and measure the resilience of the Sorong Timur District in facing flood disasters through an evaluation approach focusing on infrastructure, service facilities, socio-economic factors, community capacity and preparedness, and institutional aspects. It was concluded that the infrastructure variable is still moderate, while the socio-economic variable, basic capacity, and community preparedness, as well as institutional capacity, are still low. Meanwhile, service facilities are also low. Overall, it can be concluded that the resilience of the Sorong Timur district in facing hydrometeorological disasters is weak.

Flooding is a hydrometeorological disaster that frequently occurs in Jayapura City, especially in the catchment areas along the Acai River Basin. One of the main factors causing flooding is increased sedimentation triggered by massive land-use changes. This study aims to analyze the relationship between land conversion, increased sedimentation, and flooding in the catchment areas belonging to the Acai River during the period 2014–2024. The method used is a mixed-method approach that combines quantitative, qualitative, and spatial analysis. Data were collected through satellite image interpretation, field surveys, sedimentation measurements, and interviews with the community and related agencies. Spatial analysis was conducted to identify the dynamics of land-use changes and sedimentation zoning. Meanwhile, hydrological analysis was conducted using the Mononobe method and rational calculations to calculate the maximum flood discharge based on annual rainfall and runoff coefficient. The results of the study indicate that over the past decade there has been an increase in built-up land area of ​​more than 80%, which has resulted in an increase in runoff coefficients from 0.223 in 2014 to 0.370 in 2024. The maximum flood discharge has also increased significantly from 60.56 m³/s to 100.41 m³/s. Furthermore, river sedimentation has also increased drastically, especially in the middle and downstream parts of the watershed. The correlation map shows that areas experiencing significant land use conversion are also locations with high sedimentation levels and recurrent flooding. These findings indicate a strong link between land use conversion and increased flood risk through sedimentation mechanisms that provide river channel capacity. Therefore, an integrated watershed management strategy is needed, including controlling land use conversion and restoring riverbank vegetation to minimize the impact of future flooding.

This research was conducted from June to July 2025 in Binjai City, with the primary focus being analyzing the readiness of the Binjai City Regional Disaster Management Agency (BPBD) to implement a flood early warning system utilizing artificial intelligence (AI). The data collection process was conducted through a literature review, which involved reviewing various theories and previous research results regarding the application of AI and Internet of Things (IoT) technology in the context of disaster mitigation. Based on the results of the study, it was found that the use of technologies such as ultrasonic sensors, microcontrollers, fuzzy logic, and automatic notification systems can provide real-time warnings with a high level of accuracy and a fast response. This system enables early detection of rising river levels through automatic measurements, intelligent data processing, and sending notifications to authorities and affected communities within seconds. By integrating historical data and machine learning-based predictions, this system is also able to depict potential flooding before it occurs, providing a longer response time for evacuation. However, the readiness of the Binjai City BPBD still faces various challenges, such as limited digital infrastructure, the need for human resource training in the technology field, and inadequate budget allocation. Therefore, cross-sector collaboration and ongoing policy support are needed for optimal implementation of this system. The use of AI and IoT in early warning systems is not only technically relevant but also urgent in the face of increasing climate change and flood risks. A strategy involving cross-sector collaboration between government, academia, and the private sector is needed to develop an adaptive and sustainable early warning system.

Flooding is a natural disaster that still frequently occurs in Singkep District, Lingga Regency, Riau Islands Province. This disaster has quite serious impacts on the community, both in the economic, social, and health sectors. Therefore, the problem of flooding should be a serious concern for the local government, particularly in improving the effectiveness of coordination between agencies directly involved in flood mitigation efforts. This study aims to determine the coordination process between the Regional Disaster Management Agency (BPBD) and the Public Works and Spatial Planning Agency (PUTR) of Lingga Regency in flood management, as well as to identify obstacles encountered in its implementation. The research method used is qualitative with a descriptive approach. The researcher uses the coordination theory of Harold Koontz which emphasizes four important elements: work planning, meetings or interactions, communication, and division of tasks. Data were collected through in-depth interviews, field observations, and documentation from both related agencies. The results of the study indicate that inter-agency coordination has not been running synergistically. The work plans of each agency have not been fully integrated, resulting in the implementation of the flood mitigation program running independently based on their respective duties and functions. The Regional Disaster Management Agency (BPBD) places greater emphasis on non-structural mitigation approaches such as education and simulations, while the Public Works and Housing Agency (PUTR) focuses on technical aspects such as flood control infrastructure development. Inter-agency meetings remain formal and have not yet become collaborative forums for formulating joint policies. Communication and task allocation have occurred, but are limited to the information dissemination stage. Key obstacles to this coordination include budget constraints, a lack of competent personnel, and low public awareness and participation in supporting mitigation programs. The lack of drainage construction in several affected villages also demonstrates weak inter-agency integration in program implementation.

West Sumatra Province, particularly Tanah Datar Regency, is one of Indonesia’s disaster-prone regions, recently affected by a cold lahar flood triggered by the volcanic activity of Mount Marapi. This disaster caused severe infrastructure damage and fatalities, posing significant challenges to the effectiveness of social aid distribution under emergency conditions. This study aims to analyze the implementation of adaptive governance principles in the distribution of social assistance by the Social Affairs Office of Tanah Datar Regency, focusing on four main pillars: collaboration, coordination, social capital development, and capacity building. A qualitative descriptive method was employed, involving in-depth interviews, field observations, and documentation of 15 key informants from various stakeholders. The findings reveal that collaborative and coordinative practices have been functionally applied but remain largely informal and undocumented within a systematic framework. Community social capital played a critical role in supporting aid distribution, though it has yet to be fully institutionalized. Meanwhile, institutional and human resource capacity faces limitations, particularly in the use of information technology and preparedness for large-scale disasters. The study concludes that the application of adaptive governance in disaster management requires strengthened coordination structures, real-time information systems, and active community engagement across all governance processes. This research contributes both theoretically and practically to developing a more resilient, inclusive, and responsive model for post-disaster social aid distribution.

Penelitian ini mengevaluasi dan membandingkan strategi pengendalian banjir di kawasan Sungai Cikeruh, Sapan, Kabupaten Bandung, yang rawan banjir akibat luapan sungai dan perubahan tata guna lahan. Analisis hidrologi menggunakan data curah hujan maksimum tahunan (2001–2023) menunjukkan bahwa distribusi Gumbel paling sesuai untuk menentukan hujan rencana. Debit puncak banjir periode ulang 20 tahun diperoleh sebesar 150 m³/s menggunakan metode Hidrograf Satuan Sintetis (SCS) yang telah dikalibrasi. Simulasi hidraulika dengan HEC-RAS 2D membandingkan kondisi existing dengan dua alternatif: pembangunan tanggul dan normalisasi sungai. Hasil menunjukkan bahwa pembangunan tanggul efektif menghilangkan genangan, sementara normalisasi sungai meningkatkan kapasitas aliran dari 75 m³/s menjadi 136,67 m³/s, meskipun terdapat kebocoran pada drainase kecil. Evaluasi alternatif menggunakan metode Weighted Average berdasarkan tujuh kriteria, termasuk efektivitas, biaya, dan dampak sosial. Hasilnya, pembangunan tanggul dipilih sebagai solusi paling efektif dan efisien. Penelitian ini memberikan rekomendasi teknis dalam perencanaan pengendalian banjir Sapan, dengan penekanan pada pentingnya pemeliharaan sistem secara berkelanjutan.  

Hidrograf banjir umumnya digunakan dalam ilmu hidrologi untuk menganalisis dan menentukan besarnya debit banjir rencana. Salah satu masukan penting dalam analisis ini adalah model distribusi hujan jam-jaman, yang mengubah hujan rancangan menjadi hujan jam-jaman. Meskipun data hujan per jam hasil pengukuran dapat digunakan untuk mengembangkan model ini, metode empiris alternatif seperti Mononobe dan Alternating Block Method (ABM) dapat digunakan ketika data pengamatan tidak tersedia. Penelitian ini menggunakan metode kuantitatif dengan pendekatan komparatif. Hasil penelitian menunjukkan bahwa hidrograf banjir yang dihasilkan dengan menggunakan model distribusi curah hujan Mononobe menunjukkan korelasi dan akurasi yang lebih baik dibandingkan dengan yang dihasilkan menggunakan model ABM, terutama jika dibandingkan dengan hidrograf berdasarkan model distribusi hujan terukur. Temuan ini didukung oleh koefisien korelasi (r) sebesar 0,9990 dan nilai koefisien normalized root mean square error (NRMSE) sebesar 0,1606. Oleh karena itu, untuk studi kasus yang dilakukan di DAS Progo, model distribusi empiris Mononobe merupakan alternatif yang sesuai ketika data curah hujan per jam tidak tersedia.

Banjir merupakan bencana hidrometeorologi yang paling sering terjadi di Indonesia, dengan frekuensi kejadian yang terus meningkat setiap tahun. Dalam perencanaan infrastruktur, khususnya bangunan air, analisis banjir penting untuk menjamin keamanan struktur. HEC-RAS 2D banyak digunakan dalam pemodelan banjir karena efisien dan mampu memodelkan sebaran genangan secara akurat. Salah satu tantangan utama adalah keterbatasan data berkualitas, seperti Digital Elevation Model (DEM). Penelitian ini bertujuan untuk melakukan pemodelan banjir menggunakan HEC-RAS 2D pada perencanaan jembatan di Sungai Mempawah sebagai bagian dari desain awal jalan hauling pengangkutan bauksit di Kabupaten Mempawah, Kalimantan Barat, serta mengevaluasi kombinasi DEMNAS dan data terestris untuk mengatasi keterbatasan data. Analisis hidrologi menggunakan metode hujan-limpasan dan hidrograf debit menggunakan metode Hidrograf Satuan Sintetis Snyder. Simulasi dilakukan menggunakan konfigurasi mesh 5×5 m, interval komputasi 10 detik, koefisien Manning 0.06 dan periode ulang 100 tahun. Luas DAS sebesar 1324,09 km², curah hujan rencana 234.5 mm, dan debit puncak 2733.48 m³/s. Muka air banjir mencapai +39 meter, kedalaman 15 m, dan kecepatan 4.48 m/s. Freeboard antara muka air dan jembatan hanya 0.3 meter, di bawah standar minimum 0.5 meter, sehingga perlu penyesuaian desain. Kombinasi DEMNAS dan data terestris terbukti efektif dalam pemodelan banjir.

Tidal flooding is an event of a natural phenomenon when sea water rises to land due to the influence of changes in sea tides, which causes waterlogging around the coastal area. This tidal flood hit the Demak-Semarang area, especially in the Sayung District area, which hampers and impacts community life. The purpose of this analysis is to analyze public sentiment regarding the impact of tidal flooding in Demak Regency using data obtained from social media, and the results of the analysis can be used as an evaluation for the government and related parties to formulate more responsive and effective policies to overcome the problem of tidal flooding. The SVM (Support Vector Machine) method is used to classify sentiment from each data into positive, negative, or neutral categories. The results of the analysis using SVM showed 3580 initial data, after preprocessing, 3147 data were obtained, with sentiment results of 1581 neutral opinions, 1257 negative, and 309 positive. Most opinions are neutral, indicating that people consider tidal flooding as a natural phenomenon and are used to dealing with it. However, significant negative opinions indicate dissatisfaction with the government's handling, while positive opinions are very minimal. SVM showed 84.44 percent accuracy, 86.7 percent precision, and 97.8 percent recall. The study recommends improvements in flood mitigation, assistance for affected communities, and infrastructure improvements.

Population density on the banks of the Ciliwung River, especially in the Pasar Minggu, South Jakarta, continues to experience a significant increase. This study aims to analyze the impact of population density on flood frequency and environmental degradation in the area. The method used is a mixed approach with descriptive-analytical methods, then data is collected through observation, interviews, questionnaires, and documentation. The results of the study indicate that the high population density on the banks of the river narrows the water flow and increases the volume of household waste that is directly discharged into the river, thereby exacerbating the risk of flooding and reducing the quality of water and the surrounding environment. The conclusion of this study emphasizes the importance of cooperation between the government, community, and other stakeholders in settlement planning, waste management, and environmental education and monitoring on an ongoing basis as an effort to mitigate flooding and improve the environment in the riverbank area

This study aims to evaluate the transparency and effectiveness of the use of the 2025 Regional Revenue and Expenditure Budget (APBD) in flood management in DKI Jakarta Province. Although the provincial government has allocated a large budget, the problem of flooding is still an annual issue that has not been resolved. Using a qualitative case study approach and George C. Edward III's policy implementation theory as an analytical tool, this study examines four key variables: communication, resources, implementer disposition, and bureaucratic structure. The results of the study indicate that policy implementation faces various obstacles such as communication with minimal public participation. Limited technical and human resources, implementer caution due to bureaucratic pressure, and weak integration between agencies. This study concludes that the problem of flooding in Jakarta is not only related to technical aspects, but is also a reflection of the suboptimal regional financial governance and sustainable and accountable public policy implementation system.

Flooding is a disaster that comes from nature directly, whether it is caused by the frequency of high rainfall or the capacity of rivers that are unable to stem the swift flow of water. Thus, appropriate measures (Mitigation) are needed to be able to cope with flood natural disasters. This research intends to conduct an in-depth field study related to flood disasters in Kudus Regency and its mitigation guidelines. Then the researcher evaluates whether the mitigation measures can have a significant impact on the decline of flood natural disasters in Kudus Regency. The research method in this study applies qualitative with a field study approach style. Based on the previous research, it was found that several measures have been taken to mitigate the occurrence of flood disasters. However, these steps have in fact not been able to overcome flooding in Kudus Regency. Based on the results of an in-depth analytical study by applying the theory of policy effectiveness by Joseph John Campbell, it was found that several flood disaster mitigation efforts carried out by the Kudus Regency Government were still ineffective because they had not been able to significantly reduce the incidence of flooding. Policy improvements and more assertive program implementation are needed so that the results are more optimal.

This research discusses the strengthening of community roles in supporting the sustainability of pump house operations as an effort for flood mitigation in Sampang Regency. The frequent floods in this area are caused by geographical factors and an inadequate drainage system. This study aims to explore the active role of the community in the management and maintenance of pump houses. The method used in this research is a descriptive qualitative approach, with data collection through interviews, surveys, and observations. The findings indicate that community participation in monitoring the condition of the pump houses and maintenance activities significantly contributes to the effectiveness of flood mitigation. However, there are still challenges regarding the community's understanding of the functions and importance of pump houses. The implications of this study recommend enhancing education and socialization to the community to increase their involvement in the sustainability of pump house operations, which is crucial in reducing flood risks in the future.
