Disasters can occur anywhere and anytime that can disrupt various aspects of a person's life, children are one of the groups of people who are vulnerable to natural disasters. This vulnerability is caused by the limited understanding of the dangers of disaster risks in their surrounding environment. So involving children in disaster mitigation efforts is one of the efforts to strengthen children's resilience in facing disasters in the future. This study uses a descriptive qualitative method with a classroom action research approach implemented at SD Islam Arraisiyah. The subjects were 18 students in grade 5 (five). The implementation of the simulation method in flood disaster mitigation efforts for students starts from the planning stage, implementation stage, observation stage, and reflection stage. There was an increase in student understanding after the socialization and preparedness training using the simulation method, as seen from the number of students who answered correctly in the post-test the efforts they could make to save themselves, namely 15 students answered correctly about flood prevention efforts, 12 students answered correctly about the efforts they could make when a flood disaster occurs, and 17 students answered correctly about the efforts they could make after a disaster occurs.

Land cover change has a significant impact on the hydrology of watershed areas, including increasing flood risk. This study aims to analyze land cover changes in the Siborgonyi and Acai sub-watersheds between 2013 and 2022 and their impact on flood potential. The methods used include spatial analysis with GIS, flood modeling using HEC-RAS, and Curve Number (CN) calculations to identify changes in soil infiltration capacity. The results show that land cover changes have a substantial effect on the increase in flood risk. The reduction of forest areas and the expansion of built-up land indicate a large-scale conversion of natural vegetation into residential and infrastructure areas. CN values in 2022 increased across most areas, indicating reduced soil infiltration capacity and increased surface runoff. Flood modeling shows that both the extent and depth of inundation significantly increased in 2022, particularly in downstream areas with basin-like topography.

Waropen Regency, located in Papua Province, Indonesia, is an area with abundant natural resource potential, such as fisheries (fish, shrimp, crabs), tropical forests and biodiversity. However, the varied topography, high rainfall and geographical conditions make this region vulnerable to flood disasters. This research aims to analyze and predict flood hazards in Waropen Regency using Geographic Information Systems (GIS) such as ArcGIS. The methods used include secondary data collection (topography, rainfall, land use, and river network), data processing using GIS software, as well as spatial analysis using Digital Elevation Models (DEM) and hydrological modeling. The research results produced a flood hazard zoning map that identifies priority areas based on threat level. This map is also used to analyze the potential impact of flooding on settlements, infrastructure and agricultural land. The findings of this research provide important information for local governments and stakeholders in designing disaster risk mitigation strategies, such as building flood control infrastructure and disaster mitigation-based spatial planning. Thus, this research shows the potential of GIS in supporting effective and data-based disaster risk management in Waropen Regency.

Flood disaster is the most frequent disaster in Indonesia. Based on BNPB records throughout 2021, flood disasters have occurred 1,279 times. Poor drainage system can be one of the factors causing flood disasters. Way Mhorock Village, Abepura District is one of the areas that has poor drainage network quality. This is because Way Mhorock Village is one of the centers of community activities, so it has the potential to cause flooding. This study examines the quality of the drainage system against disasters in Abepura District by focusing on Way Mhorock Village. The research methods used to achieve the objectives in this research are qualitative methods, spatial analysis, and analytical hierarchy process. Qualitative descriptive analysis method to assist and describe the actual drainage problems in the field in the form of pictures. Spatial analysis method using GPS by recording problematic drainage points then processed using ArcGIS software. Analytical Hierarchy Process method by capture the perspective of stakeholders from the agency to determine the assessment of the quality level of the drainage system that has the potential to cause flooding in Way Mhorock Village. The results showed that there are 4 problems that affect the quality of drainage in Way Mhorock Village, namely drainage sedimentation, land use change, drainage cross section, and the volume of waste found at 33 points in Way Mhorock Village. Based on the results of the analytical hierarchy process using an expert choice application, drainage sedimentation is the most influential criterion on improving drainage quality with alternative handling provided in the form of law enforcement policies against environmental violations by the community.  

Floods are natural disasters that often occur in Indonesia and cause damage to property, infrastructure, and casualties. One of the main factors causing flooding is the failure of water management systems such as reservoirs to manage the sudden increase in water volume. This research aims to design an automatic reservoir sluice controller by utilizing Internet of Things (IoT) technology to reduce flood risk. The system uses a NodeMCU ESP8266 microcontroller and an HC-SR04 ultrasonic sensor to monitor the water level in real-time, as well as a servo motor that controls the sluices. The system is connected to the Blynk app, allowing remote monitoring and control of the sluice gates via mobile devices. This tool automatically adjusts the position of the sluice gate based on sensor data to keep the water level safe and reduce the potential for flooding. The test results show that this IoT-based automated system is able to work effectively in controlling sluice gates and can be used for flood disaster prevention in the surrounding environment.

South Tangerang City is one of the areas prone to flooding, with various influencing factors, such as a lack of communication between local government organizations and weak spatial planning supervision. Uncontrolled development by several large developers has constricted river flows, while suboptimal drainage and water absorption systems have exacerbated the situation. In flood mitigation efforts, coordination between the Regional Disaster Management Agency, the Public Works Agency and the Environment Agency is necessary to ensure anticipatory efforts and sustainable solutions. Existing Regional Regulations and Governor Regulations, including regional spatial plans and technical guidelines for flood control, are an important foundation for flood management in the region. The purpose of this research is to find out and analyze how the implementation of flood disaster mitigation policies in Regional Regulation Number 2 of 2012 concerning Disaster Management. This research uses the theory of George C. Edward III. with 4 indicators, namely communication, resources, disposition, and bureaucratic structure. The results showed that the unity of action in handling floods still faced obstacles, where the Environmental Agency had not fully carried out its responsibilities in maintaining waste in drainage channels and rivers.

Implementing disaster management is a series of efforts that include establishing development policies that are at risk of disasters, disaster prevention activities, emergency response and rehabilitation. Currently several areas in Tanjungpinang City have the potential for flooding, only the Tanjungpinang City District and Bukit Cermin sub-district are free from flooding. According to him, there are many causes of waterlogging, such as inadequate drainage, rubbish blocking ditches, and housing that does not have drainage channels, the water drainage system needs to be repaired. The flow of water in the drainage must be clear so that it does not overflow onto the roads and into residential areas. The aim of the research is to determine the efforts made by the local government in dealing with floods in Tanjungpinang City. Then in this research the researcher refers to Ndraha (Labolo, 2010:36). The method in this research is that the author uses a qualitative descriptive research type using interview and observation data collection techniques. Based on the research, it can be concluded that the Regional Government in Flood Management in Tanjungpinang City has played a role. The following research results show that the government's role as a regulator is by making rules or regulations in disaster management, which are stated in the Tanjungpinang City Regional Regulation (PERDA) Number 03 2016 concerning the Implementation of Disaster Management. The role of the dynamist is to provide intensive and effective guidance and direction to agencies and communities related to disaster management.

The synthetic unit hydrograph methods of Nakayasu, HEC-HMS (Snyder), SCS, ITB-1, and ITB-2 are used to calculate peak discharge and flood hydrograph shape in this Kadumalik Dam study. The maximum daily rainfall data analysis used the Thiessen Polygon and Arithmetic Mean methods. Of these two frequency analysis methods, the Thiessen Polygon method was chosen. Rainfall transformation into runoff using the FJ MOCK and NRECA methods has been applied in the Kadumalik Dam analysis. Compared to NRECA, the FJ MOCK method with the Thiessen Polygon method for frequency rainfall analysis provided a better performance rating with calibration values of 0.911 for R2, 0.627 for NSE, 0.606 for RSR, 18.141 for RMSE, and 30.764 for PBIAS. The validation values were 0.911 for R2, 0.661 for NSE, 0.582 for RSR, 16.086 for RMSE, and 34.420 for PBIAS. The Kadumalik Dam uses a side-channel spillway model with an ogee spillway crest type. Technically, it is planned based on the design flood discharge Q100 and controlled by discharging the flood discharge Q1000 and QPMF. The purpose of this study is to determine the hydraulic flow behavior that occurs in the numerical model based on CFD with ANSYS Fluent and CFX, along with Flow 3D in the diversion, regulation, and launching channels, to obtain the optimum design of the structures, where the flow classification is steady and transient. From the numerical analysis results, it was found that the water velocity streamline in the launch channel for Q100 with steady flow is 0.1644 – 0.2643 m.s-1, for Q1000 it is 0.2176 – 0.2869 m.s-1, and for QPMF it is 0.1592 – 0.2262 m.s-1. For transient flow, the water velocity streamline in the launch channel for Q100 is 0.1555 – 0.2250 m.s-1, for Q1000 it is 0.1541 – 0.2232 m.s-1, and for QPMF it is 0.1559 – 0.2255 m.s-1. Wet, normal, and dry hydraulic conditions are used in the analysis of the Kadumalik Dam operation pattern. The wet hydraulic condition before the reservoir had an average discharge of 25.51 m3/s, and after the reservoir, the average discharge was 26.89 m3/s, an increase of 5.125%. The normal hydraulic condition before the reservoir had an average discharge of 15.54 m3/s, and after the reservoir, the average discharge was 18.75 m3/s, an increase of 17.105%. The dry hydraulic condition before the reservoir had an average discharge of 1.74 m3/s, and after the reservoir, the average discharge was 7.97 m3/s, an increase of 78.157%.

This research focuses on the implementation of flood management policies in South Tangerang City with suboptimal flood management problems. The problems that were found were that the coordination carried out by stakeholders was tentative, there were obstacles in communication on the condition of the social environment, expecially in terms of public awareness of protecting the environment, was still lacking because rubbish was still found in rivers and canals. The aim of this research is to determine the extent of implementation of flood management policies in South Tangerang City. This research uses a qualitative approach with descriptive methods, and data is obtained trought observation, interviews and documentation. This research uses the Van Meter and Van Horn theory with 6 (six) indicator, namely: a) Policy Size and Objectives; b) Resources; c) Characteristics of The Implementing Agent; d) Attitude and Tendencies; e) Inter-Organizational Communication and Implementation Activies; f) Economic, Social and Political Environment. The result of the study show that policy measures and standards are appropriate but there needs to be an increase in disaster outreach and training. Then the quantitiy or number of Task Forces to go into the field is still insufficient. The availability of an organizational structure and regulations responsible for implementing flood management is quite good. Policy implementers understanding of flood management policies in quite good and has received a positive response from policy implementers. Apart from that, the communication that exists between OPDs and village officials is quite good, characterized by delibration. The economic, social and political environmental conditions are quite good, but there needs to be an increase in public awareness of protecting the environment by not throwing rubbish into rivers or waterways.
