Abstract This research is based on flood conditions that often occur in lowland areas such as Jakarta and Semarang. The problem faced is that the notification and early detection of floods is often late, done manually so that it cannot be anticipated by areas downstream of the river. Therefore, it is very important to be able to develop an IoT-based early warning tool so that floods can be detected early in a fast, real time, and immediately anticipated in the upstream area of the river. This research method uses design methods and experiments carried out in the field and laboratory. This research will present a prototype of the FEDS (Floods Early Detection System), based on the Blynk application. The results showed that the calculation of planned flood discharge with a return period of 2, 5, 10, 25 and 50 years can provide an overview of the ability of an area to face the maximum possible rainfall. The FEDS prototype tool, with the Blynk application, can work well using a microcontroller, ultra sonic sensor, and a rainfall sensor. This system is suitable for use in the community to determine rain conditions and water level conditions used at river water level conditions, for early notification of floods.

[ID] Permasalahan banjir merupakan permasalahan pengelolaan air yang sering terjadi di Indonesia. Untuk mengatasi permasalahan tersebut dibuat sebuah struktur yaitu waduk yang berfungsi sebagai pengendali banjir. Namun seiring waktu tampungan waduk akan semakin menurun akibat adanya akumulasi sedimen yang terbawa oleh air sungai yang masuk ke dalam waduk dan mengendap. Sehingga diperlukan evaluasi kinerja tampungan waduk tersebut, Permasalahan ini juga dialami oleh Waduk Selorejo yang terletak di Kabupaten Malang. Untuk melakukan evaluasi kinerja tampungan waduk digunakan bantuan perangkat lunak HEC-HMS yang dapat mensimulasikan debit banjir yang masuk beserta elevasi tampungan waduk. Berdasarkan hasil analisis tampungan Waduk Selorejo mampu untuk mengendalikan banjir periode ulang desain awal nya yaitu periode ulang 1000 tahun. Selain itu Waduk Selorejo juga mampu menampung debit banjir Probable Maximum Flood (PMF) apabila muka air awal waduk diturunkan sampai elevasi +605 m. [EN] Flood problem is a water management problem that often occurs in Indonesia. To overcome this problem, a structure is created, namely DAM that functions as a flood controller. However, over time the reservoir storage will decrease due to the accumulation of sediment carried by river water that enters the reservoir. So it is necessary to evaluate the performance of the Rervoir storage. This problem is also experienced by the Selorejo DAM which is located in Malang Regency. To evaluate the performance of the reservoir storage, the help of HEC-HMS software is used which can simulate the incoming flood discharge along with the elevation of the reservoir. Based on the analysis, the Selorejo DAM is able to control the flood of  its initial design period which is the 1000-year return period. In addition, the Selorejo Reservoir is also able to accommodate the Probable Maximum Flood (PMF) flood discharge if the initial water level of the reservoir is lowered to an elevation of +605 m.

During the rainy season, several regions in Indonesia experienced floods even to the capital of Indonesia also flooded. Some of the causes are the high intensity of continuous rain, clogged or non-smooth drainage, high tides to accommodate the flow of water from rivers, other causes such as forest destruction, shallow and full of garbage and other causes. Every flood disaster comes, often harming the residents who experience it. The late anticipation from the community and the absence of an early warning system or information that indicates that there will be a flood so that the community is not prepared to face floods that cause a lot of losses. Therefore it is necessary to have a detection system to provide early warning if floods will occur, this is very important to prevent material losses from flooded residents. From this problem the researchers designed an internet-based flood detection System of Things (IoT). This tool can later be controlled via a smartphone remotely and can send messages Telegram messenger to citizens if the detector detects a flood will occur.Keywords: Flooding, Smartphone, Telegram messenger, Internet of Thing (IoT).

Disaster prediction devices for early warning system are used by many countries for disaster awareness. This study developed smart disaster prediction application using microcontrollers and sensors to analyze the river water level for flood using flood risk analytics. Specifically, it monitors the river water level, water pressure and rain fallusing microcontroller, applying statistical modeling algorithms for river flood prediction, and monitor flood in a web-based system with SMS notification and alarm to the community as an early warning. The researchers used the system development method to measure the prototype feasibility study. The researchers applied the statistical modeling algorithm as the data can be observed from time to time or on a daily basis for the predictive analytics. Based on the 7-days observation result, rainfall resulted in precipitation average of 10.96 mm, water pressure with an average of 40.92 pound per square inch (psi) and water level averaged 138.78 cm. The tropical depression during the 7 days’observation reflected the average data result from the sensors as the target of the study. The result of the prototype device used the City Disaster Risk and Reduction management office (CDRRMO) as history logs for a flood risk and it was proven accurate which makes a good use for disaster prediction.

Early warning of floods is an essential part of disaster management. Various automatic detectors have been developed in flood mitigation, including cameras. But reliability and accuracy have not been improved. Besides, the use of monitoring devices has been employed to monitor water levels in various water building facilities. The early warning flood detector was carried out with a sensor camera using an orange ball that floats near the water level gauge in a bounding box. This approach uses the integration of computer vision and image processing, namely digital image processing techniques, with Sobel Canny edge detection (SCED) algorithms to detect quickly and accurately water levels in real-time. After the water level is measured, a flood detection process is carried out based on the specified water level. According to the results of experiments in the laboratory, it has been shown that the proposed approach can detect objects accurately and fast in real-time. Besides, from the water level detection experiment, good results were obtained. Therefore, the object detection system and water level can be used as an efficient and accurate early detection system for flood disasters.
