A turquoise rectangular box with 10x10x10 cm size was not a regular thing. The object named "D'Box CC" was an air purity detector that participated in the International Exhibition for Young Inventors (IEYI) in China, in July, 2016.
The box inventors are Aan Arian Nanda (17) and Feriawan Tan (17), the students of 1st Senior High School (SMA 1) in Tarakan, North Kalimantan. The inventor was claimed to be inspired from the forest fires that swept in Kalimantan in 2015. Departing from that reason, the young man duo since November 2015 until May 2016, together with the guidance counselor at the school designed a simple air worthiness detector at minimum cost.

"The making of about six months. From the November 2015 until May 2016. The longest phase was doing research, trying to find components. Then to determine what sensor is used. As for the device alone, it took three days overtime," said Feri.
A number of components that they use include the fan to set the air supply, battery, LCD, LED, USB cable, small speakers and other components. In addition, they also create an application that serves to show the analysis of the air feasibility in real time in the form of a graph, which is accessed through the computer.
As told to Antara News, Feri explains how the "D'Box CC" works. "This is a fan that serves to compress the air. In the (rear) fan there are sensors that read the data content of CO and CO2 in the air," he said.
"After reading the data, the sensors transmit data to the micro, as the brain. From the brain that send data to the system. The system was the LED indicator and LED screens to display the data. When using a USB cable, here is the application. Thus, the data passed to the application," said Feri.
Then, when the CO2 levels in the air beyond normal limits (greater than 500 ppm) and CO (12.4 ppm), then there will be an alert sound through the speakers. Feri said, they spend around Rp.529 thousand to create this device. Nevertheless, he hopes eventually D'Box CC can be mass produced, so the selling price could be cheaper.
"In the future we want this device mass produced so the price could be cheaper. We also want to be useful for many people," said Aan.
D'Box CC some time ago also won the awards from the Indonesian Institute of Sciences (Lembaga Ilmu Pengetahuan Indonesia/LIPI) and is currently in development as well as to obtain a patent.
"We eventually want this device is more portable, wireless and can be accessed through mobile applications," said Feri. *** [EKA | FROM VARIOUS SOURCES | ANTARA NEWS]
