Flooding is an increasingly severe global hazard driven by climate change, rapid urban growth, and aging infrastructure. The World Bank (2024) estimates 1.81 billion people live in high-risk flood zones, with USD 1.3 trillion in economic losses recorded over the past 30 years. Beyond physical damage, floods also create major electrical dangers. WHO (2023) notes a 40% rise in flood-related electrocutions in Southeast Asia, and 2–3% of global flood fatalities are linked to electric shock from household systems exposed to standing water.
Indonesia faces similar conditions. As of September 2024, the National Disaster Management Agency (BNPB) documented over 750 flood events, underscoring persistent community vulnerability. Although national data rarely reports electrocution cases separately, repeated incidents—such as in Bekasi, Semarang, and North Jakarta—show that electrical hazards during floods are real yet often overlooked. Most early-warning systems only monitor water levels, leaving a critical safety gap at the household level.
To address this issue, students from the Electrical Installation Engineering program at SMKN 1 Paringin developed FLOWSAFE, an automatic electricity-cutoff system triggered by rising floodwater. It disconnects power, provides real-time monitoring, and sends alerts through Blynk and WhatsApp, offering a practical and replicable safety solution for flood-prone communities.
