The name of Indonesia was again mentioned in the international competition. Precisely at the Korea International Youth Olympiad – Idea, Innovation, Invention, and Intellectual Property (KIYO 4I) event in Seoul, South Korea. Representatives from Indonesia, followed by three students from the Sepuluh Nopember Institute of Technology (ITS) Surabaya, East Java. Their present innovations that make juries give more value than other participants.
The ITS team consisted of Reza Aulia Akbar, Ragif Nova Riantama, and M Afif Purwandi with guidance from Dr. Adithya Sudiarno. In addition to these innovations, the three also innovated to create tools to detect fatigue through heartbeat and blinking of the eyes. They overall managed to bag one silver medal and two bronze medals.
The innovations created by them cannot be separated from the conditions of international workers. Reported by the International Labor Organization, around two million workers die each year due to work accidents. Where 32.8 percent of them are caused by fatigue.
The innovation, called Fatigue Detector (Fator) and Machinist Fatigue Detector (Maftec), managed to qualify for the final round at the KIYO 4I event held at Sejong University, Seoul, South Korea. Fator uses the Arduino ECG (Electrocardiogram, red) sensor in the series, the scheme is to calculate the heart rate of the workers. Unlike Fator, Maftec detects fatigue from eye blinking. Sudiarno said that Maftec was intended to detect the exhaustion of train drivers.
Through a webcam image processing with a light intensity of 16 lux, the results of the number of blinks are converted into Karolinska Sleepiness Scale. If the driver is sleepy, this device will send a vibration signal to the train command center.
According to an expert lecturer in Operational Management, the cardiograph sensor mounted on the device measures how fast the heart is beating. The results are then compared with data from the journal to obtain fatigue.
Obtained through image processing webcam with a light intensity of 16 lux, the results of the blinking count are then poured into the Karolinska Sleepiness Scale.
This tool will send a vibration signal to the train command center if it is concluded that the machinist concerned is sleepy. Both of these tools successfully won silver and bronze medals.
