UNAIR NEWS – Water pollution in Indonesia is getting more alarming. The accumulating plastic waste has discouraged tourists from going to the beach. The accumulation of garbage and heavy metals in coastal areas deteriorates the quality of ocean water.
From this problem, two students of Faculty of Fisheries and Marine Sciences (FPK) Universitas Airlangga, Yolandha Sepiani Nurhanifah and Reza Istiqomatul Hidayah came up with an idea to make an innovation with Ocean Cleanliness Detection Tool based on Internet of Things (IoT) and Automatic Alarm as Controller of Water Environmental Conservation, abbreviated as ATLANTIS. .
“As students of fisheries and marine sciences, we are irritated by the problem of water pollution, so we came up with the idea to create a technology that can detect ocean cleanliness based on Internet of Things with the product name ATLANTIS,” said Reza as the team leader.
This innovative idea won first place in Product Innovation Category for 2020 National Student Innovation and Creativity Festival at Khairun Ternate University.
Reza explained that ATLANTIS depends on the internet. It works using a digital camera that is used to visualize the state of the sea, then records and sends signals to the microcontroller in the form of an Arduino UNO connected to an LCD (Liquid Crystal Display) display. It is connected to a computer to detect plastic and heavy metal waste contained in the water. Simultaneously, when the LCD displays data on sea water conditions, there is an automatic alarm that will make sound and light up according to the level.
“Green for normal, yellow for alert, and red for danger,” said the Aquaculture student from the class of 2017.
The green, yellow and red lights, continued Reza, have tolerance limits or thresholds in the waters. So, an alarm will sound every 30 days in order to monitor the conditions of sea waters.
Reza encouraged other students to start new things and explore the nature more. “Let’s be sensitive to the local environment. Because if not now, then when? If not us, then who?, ” she concluded. (*)
