Torsion Dynamometer Application for Detecting Water Was Contaminated by Detergent

Abstract

Research on the Torsion Dynamometer application to water was contaminated by detergent has been carried out. This research aims to develop alternative methods for detecting water was contaminated by detergent. This research is conducted in three stages, including preparation of tools and materials, data collection, and data processing. The results of this research indicate water was contaminated by detergent has the characteristics of surface tension ɣ=(0,256x10-1
±1,354x10-4)N/m while, normal water has the characteristics of surface tension ɣ=(0,490x10-1
±1,687x10-4)N/m. Therefore, Torsion Dynamometer can be used as an alternative method to distinguish between water was contaminated by detergent and normal water.
