Keywords

💡Flood

Flood refers to an overflow of water that submerges land which is usually dry. In the context of the video, floods are a common disaster in Indonesia, highlighting the need for careful handling to minimize damage. The script mentions the creation of a flood warning system to address this issue.

💡Disaster Management

Disaster management involves the organization and management of resources and responsibilities to deal with disasters. The video script indicates that floods need to be managed carefully by all parties, which is a key aspect of disaster management in Indonesia.

💡Innovation

Innovation is the process of translating an idea or invention into a good or service that creates value or for which customers will pay. The script discusses an innovation for detecting floods using easily obtainable materials, which is a creative solution to a common problem.

💡Materials

Materials in this context refer to the substances used to make something. The video script lists materials like a buzzer, battery, styrofoam, and aluminum foil, which are used to create a flood alarm, demonstrating the use of everyday items for innovative purposes.

💡Buzzer

A buzzer is a device that makes a buzzing sound, often used as a signal or alarm. In the video, a buzzer is connected to a battery to create an alarm system that will sound when the flood detector is triggered by water.

💡Styrofoam

Styrofoam is a type of foam plastic often used for insulation or as packaging material. In the script, styrofoam is used as part of the flood detection mechanism, where it is coated with aluminum foil and used to trigger the alarm when it comes into contact with water.
