This paper proposed a low-cost coral monitoring system based for shallow water based on IoUT architecture. The proposed system consists of buoy as base component, controller unit based on Single Board Computer equipped with 5V power source, underwater camera and communication unit to send data into cloud server. This system is able to extend WiFi signal from underwater camera by using coaxial cable and transmit image into cloud server. From experiment, we measured that reliability delay using coaxial cable to capture and save image is 5,6 seconds. Results on cloud server experiment indicate distributed server’s performance is 186,6 seconds comparing to 53,6 seconds on single server. Moreover, we also have developed bleaching classification resulting 84,3% correct results and an online representation model of retrieved coral images.}, number={2-5}, journal={Journal of Telecommunication, Electronic and Computer Engineering (JTEC)}, author={Abdillah, Abid Famasya and Berlian, Muhammad Herwindra and Fridelin Panduman, Yohanes Yohanie and Akbar, Muhammad Aditya Wildan and Afifah, Marlanisa Arifatul and Tjahjono, Anang and Sukaridhoto, Sritrusta and Sasaki, Shiori}, year={2017}, month={Jun.}, pages={97–101} }
