“…Several efforts to minimize the effects of flooding have been carried out to reduce losses, including: rearranging river basins in an integrated manner, not constructing buildings on riverbanks, constructing infiltration wells, normalizing rivers and installing pumps and sluices in flood-prone areas (Fathaya et al, 2020) (Apriadi & Saggaf, 2021) (Aji Laksana & Pratiwi, 2020). To help anticipate the arrival of floods is to build an early arrival warning system floods and water levels through short message technology so that residents can immediately prepare themselves in the event of a flood disaster (Ferdiansyah et al, 2020) (Attia et al, 2019) (Wan Hassan et al, 2019) (Abana et al, 2019). Sensors or detecting the presence of overflowing water play a very important role in building early warning equipment for flood arrivals.…”
