Abstract

This research is a quantitative study to determine the effect of educational background on the understanding of the science concept of UPY PGSD students. This research is based on the low understanding of the science concept as evidenced by the percentage of science learning test results, namely 67.6% of the total number of semester 2 PGSD UPY students scored below 80. The method used in this research is ex post facto quantitative which is used to determine the cause of the low understanding of students' science concepts in terms of their educational background. The data collection used an educational background questionnaire and a science concept understanding test that had been tested for validity and reliability. The research shows the results of the t-test namely tcount<ttable (0.095 < 0.931), then Ho is accepted and Ha is rejected, which means that there is no significant influence between students' educational background on the understanding of science concepts. However, there is a unidirectional relationship between the two with the result of a positive correlation test (r) of 0.055 and contributing an influence of 0.3% from the educational background on understanding the science concept of PGSD UPY students.

Abstract

In this research, the diffusion coefficient of phosphate ions in agarose-citric acid diffusive gel has been studied. The agarose-citric acid diffusion layer was prepared by mixing 1.5% agarose solution with the addition of citric acid solutions at various concentration. The diffusive gel was casted between two glass plates which were separated using a spacer of 0.1 cm thickness and clamped together in the three sides. Gel was formed for 15 minutes in an oven at 40oC. The diffusion coefficient then was calculated using Fick's First law formula. Gel that produced with addition of 0.45% citric acid absorbed more water during immersion in water for 3 hours for facilitating phosphate diffusion. Swelling degree of the agarose citric acid diffusive gels was not affected by the storing solution condition either in water or in NaNO3 0.1 M. Coefficient diffusion of phosphate in the agarose-citric acid diffusive gel was 1.009×10-7 cm2s-1, less than the diffusion in the pure agarose gel 1.367×10-7 cm2s-1. The diffusion is affected by the ionic strength of solution. Phosphate diffusion coefficient is higher in the phosphate solution with addition of 2 mgL-1 nitrate. Increasing the ionic strength causes lower phosphate diffusion coefficient because the electrostatic attractive and repulsive force
