Abstract

This research is related to a design of water quality improvement device using sustainable design that will be placed in the Lake of Universiti Teknikal Malaysia Melaka (UTeM) Main Campus The device is able to increase the level of dissolved oxygen in lake water by using natural resources. In addition, it reduces the time taken for researcher to retrieve data in the lake for experiment by implementing IoT. The research was conducted at Tasik B, UTeM where segmentation method is used to carry the water sample analysis process. The method is used because the physical properties of the lake water may differ due to the large surface area of Tasik B with the area of 48,076 m2. The lake has been segmented into nine segments with 10 data taken from each segment. The data are considered after the implementation of water quality improvement device and comparisons has been made with previous data. The design of the device has involved several concepts using the Pugh matrix. The selected design in then designed in CAD software, Solidwork to obtain solid modelling. For the implementation of IoT, schematic diagram is drawn before the code being develop. The result of implementation of IoT shows the time taken for water quality research for 120 minutes to 10 minutes. Besides that, with the implementation of IoT technology, data can be accessed online via computer or smartphone. The overall findings of the project indicate that the DO level of Tasik B, UTeM is improved by 23% after applying water quality improving device that contain natural source. The use of IoT giving a new dimension to the conservation of water quality. Furthermore, the device can be further expanded to other application in the future.
