Abstract

Electrical conductivity can be achieved not only on solid form, but also in liquid form or semi-liquid. A renewable source of energy such as seawater could be the ideal path for conductivity. To prove this, a study of temperature testing was done on a few samples of seawater to relate it with electrical conductivity. The aim of this study is to explore the relation between temperature variation and conductivity by developing a relationship using Chi-square Independence Test and compare the conductivity strength performance of two different temperature measures. Other statistical method to relate both parameters were applied to find its correlation. Few samples of normal seawater temperature at atmosphere were taken from Pantai Klebang, Melaka and underwent ohmic heating process. Both measurement were taken and being compared for the conductivity strength performance. Measurement of conductivity and temperature were taken by using EC Meter and PID controller. The two variables being tested were the temperature (˚C) and the electrical conductivity (μS/cm) of seawater. The statistical analysis of Chi-square Independence Test on the samples using Minitab software had shown the dependency of conductivity on temperature. Conductivity strength performances of two temperature measures were tested using Hypothesis Testing. The test show that conductivity at ohmic heating temperature was greater than conductivity taken at normal temperature of seawater.
