Abstract

Water resources have been depleting in recent years. Statistics show that India, China, and Nigeria are the top three countries with a large number of deaths each year regarding water pollution. Water pollution can have negative effects on the health, environment, and economy. Furthermore, it can also bring impact on climate change that, resulting in higher water level, can cause floods and bad weather. In Malaysia, the beverage industries are one of the main water pollution contributors. All of these problems have also happened in Melaka. Sungai Melaka is currently being contaminated that has caused the death of fish diversity. Law enforcement, water recourse regulations, religious and moral education regarding the importance of rivers have all been implemented by the Melaka state government. However, the implementation of such initiatives has not resulted in lower levels of water contamination. The issue has progressed to a greater level, and it has grown more serious. Therefore, the main pollutants emitted by the major sources of pollution should be studied and identified, particularly in terms of spatial variation in Sungai Melaka. In this study, a Hydro Quality Survey System or HydroQS device will be implemented based on the best selection of material which is PA-12 Nylon powder, FS3200PA. The reason why PA-12 is chosen is that it suits the SS402P SLS 3D Printing machine that has been selected for printing HydroQS housing. This study will perform a field test to determine the mechanical properties and hygroscopic growth of the aging FS3200PA and to measure the dimension stability of the sintering samples. This study is to test the HydroQS housing based on the sample shape to be sent to 50KN Universal Tensile Machine (UTM) and the sample shape will be tested in Sungai Melaka. The HydroQS housing that will be produced is expected to have a lightweight, high strength, and low drag coefficient and fulfill all PPSPM concerns and requirements.
