Abstract:
In general, water filters use organic materials that have various functions and advantages. Therefore, this product has been innovated in the FYP project using organic materials as one of the ways to filter dirty water into clean water. Among the objectives listed in the making of this project is to create a water filter from the kitchen sink. In addition, the second objective of this project is to identify the pH value and determine the Biochemical Oxygen Demand (BOD) value before and after filtering. Next, the objective of this product is produced to determine the turbidity value of the water before and after filtering. This product undergoes two tests, the first is the Biochemical Oxygen Demand (BOD) test to find the amount of dissolved oxygen required by microorganisms to decompose organic matter. The second test is to test the turbidity of the water whether the water is in a suitable condition for use according to the set standards. Both of these tests use two water samples which are water before filtering and water after filtering. There are five materials used in the filter, which are cloth, rice husk, sugar cane bagasse, gravel, and silica sand. Each material has its own function as a nurse of polluted water. However, this project only focuses on daily use and its water is not suitable for drinking. Among the daily activities that can be done using the filtered water are watering flower plants, washing the car and more.
