Indonesia IPB Students Created Indonesian Marine Waters Measuring Technology
The rapid development of Information Technology is utilized by various fields including in marine science. Telemetry, one of the IT field, is an automated communications process by which measurements and other data are collected at remote or inaccessible points and transmitted to receiving equipment for monitoring. A group of students consisted of Muhammad Sanubari, Slamet Riyanto, Imam Syafi'i, and Agung Tri Nugroho, under the PKM Karsa Cipta (PKM KC) Program utilized telemetry technology to monitor the current state of Indonesian waters.
With reference to degradation of water resources quality in Indonesia and common problems of data collection due to the existing equipment in Indonesia, the group had insisted that data collection should be conducted directly. However data collection utilizing such method will cause big problem as they cost a lot of funds and the data collected will be based on the proxy measures. Muhammad Sanubari together with PKM KC team initiated a telemetry-based seawater measuring device called “Simetri”.
“Simetri” is designed to address the emerging need to simultaneously measure a range of biological and physical properties in both fresh and seawater environments. It allows people to access water resources data through the website, and the data presented are the latest under sea data recorded by “Simetri”. Telemetry technology will record the temperature, salinity, and turbidity of seawater environments. Those data are transmitted with wireless data nodes underwater, then data are pushed to the Internet for access. Information can be viewed or downloaded based on user needs.
“Simetri” is made up of many different but connected parts, one of which is casing. It is the platform for series of sensors to be installed under water. Casing is designed for easy disassembly and packed easily. The sensors are stored in a watertight room and connected to a component box that is above the surface of the water coincide with buoyant.
Raspberry pi 3, WiFi modem, RTC DS1307, arduino mega microcontroller, and Accu resources are installed the component box. The component and the sensor boxes are connected using the data transmission cable, the sensor obtained results are sent to Raspberry using phyton language. The data was processed by raspberries to be sent to the MYSQL database via the internet network. Database could store the control files and online system and will be presented in the web page. “Simetri” website is designed using various programming languages such as CSS, PJP, Javascript, HTML, XML, and Coldfusion.
“Simetri” will provide the various methods and technologies used to measure water quality for academic purposes and so on. Those data are required for an integrated policy and decision-making process for marine management. The protection and conservation of marine biodiversity and their utilization will maintain the wealth of our biota and ecosystems. (Wied)
