Abstract

This study aims to remediate student misconceptions on dynamic electrical materials. Remediation activities are conducted in two stages. First, the  development of guided discovery learning devices and misconception diagnostic test instruments. The development follows the 4-D model stage. The second phase is, the implementation of learning in 35 students of Physics Education in 2011 State University of Surabaya through Design One Group Pretest-Posttest Design. Student misconceptions data were analyzed by CRI analysis and learning implementation data were analyzed by mean of stepping. The data of the research shows that the average value of learning is 3.6 (very good category). Initial misconception profiles are found on every concept before learning and decline after remediation. At the drift speed concept, students experienced misconceptions 66% and 31% after application. In the concept of 'Ohm's law' 26% to 3%, source voltage parallel series strewed 71% to 43%, current consumption model 63% to 46%, series and parallel impact on power 80% to 46%, energy on battery 40% to 37%, electrical circuit typology 69% to 51%, electric power in mixed circuit 51% to 17%, current on a circuit 40% to 11%, potential difference between two points 43% to 9%, use of measuring instrument electricity (ampermeter and voltmeter) in the series 37% to 26%, and Kirchhoff rules 20% to 26%. The results of this data analysis can be concluded that the learning tools developed can reduce student misconception.

Abstract

The study on the optical, electrical properties of multilayer graphene (MLG) obtained by thermal-reduction of graphene oxide (GrO) which was synthesized directly by mixing graphite oxide (GO) flake in 0.005, 0.01, 0.015, and 0.02 M of Au aqueous solution has been successfully performed. The resultant  GrO was subjected to an annealing temperature of 200°C, 400°C, 500°C for 1h to obtain MLG, and G-Au2x, G-Au4x, and G-Au5x (x=.0.005, 0.01, 0.015, and 0.02). The resultant samples were then characterized using FESEM, UV-VIS, four-point probe measurements to study its morphology, optical, and electrical properties. The transmission G-Au increase and its sheet resistant decrease as an increase of annealing temperature. Besides, the annealing treatment was then achieved of its microstructure which is expected may be used as a counter electrode in solar cell applications. The best DSSC devices with Quartz/FTO/ZnO Nanorods/Dye/G-Au50.01/Quartz structures have resulted in current-density, Voc, and solar cell performance of 0.1 mA/cm2, 0.42 V, and 0.01%, respectively.

Abstract

[Title: Development of Lightweight Brick Based on Traditional Gold Processing Waste with Water Hyacinth Booster]. Research has been carried out on the manufacture of light brick made from gold processing waste with water hyacinth filler. The study was carried out by varying the direction of water hyacinth fiber as filler in light brick making. The direction of the filler is arranged in a horizontal, orthogonal and random direction. In each filler direction, the percentage variation of water hyacinth is arranged with the volume fraction 0%, 15%, 30%, 45%, 60%, from the total volume of the amount of light brick. The test results show that in the horizontal fiber direction the compressive strength is (2.43; 0.25; 0.54; 0.24; 0.50) MPa with a density (1.62; 1.34; 1.58; 1.42; 1.25) gr /cm3. In orthogonal direction the compressive strength was (2.43; 0.26; 0.80; 0.63; 0.77) MPa with density (1.62; 1.42; 1.49; 1.53; 1.42) gr/cm3. While in the random direction the compressive strength was (2.43; 0.73; 0.69; 0.59; 0.65) MPa with a density (1.62; 1.20; 1.41; 1.13; 1, 20) gr/cm3. From these data by comparing with previous studies, the most stable compressive strength and density values are formed in orthogonal directions. While the density value is most formed in random direction. In all directions the compressive strength and stable density were formed in the 60% volume of filler. The test results show that the light brick that is formed into the category is very light (entered in 0.6 - 1.6 gr/cm3 range) and floating in water, with medium compressive compressive strength.
