Abstract
This research is based on the needs for an innovative experimental learning media in the study of physical chemistry, focus on conductivity of electrolyte solutions. Through Research and Development with the stages of analysis, design and development, the electrolyte solution conductivity meter has been produced. Based on the results of the research, it was obtained the product in the form of an electrolyte solution conductivity measuring instrument equipped with a user guide to the use of an electrolyte solution conductivity measuring instrument and an experimental worksheet measuring the conductivity of an electrolyte solution. The electrolyte solution conductivity meter is designed to measure the conductivity of an electrolyte solution and can compare the conductivity values of fruit juices, vegetable juices and isotonic drinks quantitatively based on Kohlrauschs law with simple and easy tools and materials to obtain. Validation results indicate that the product is declared valid with the acquisition of an average value of R is 0.83. The results of the feasibility tests conducted on chemistry education students show that the electrolyte solution conductivity gauge is declared very feasible with an average value of 93.85%.
