Abstract

This research aims to obtain the electrical characteristics and photoelectric material measured by two point probe method using I-V measurement and to know the photoconductivity of the material measured by two point probe method with the multimeter circuit. Research using experimental method. The activities of research on the design of electrical characterization tools with two point probe method and optimization. Electrical characterization testing is carried out with material conductivity characteristics and compares it with a Elkahfi I-V meter as standar measurement. This result of research can be concluded that two point probe method with multimeter can be used to measure the conductivity and photoconductivity of the material. The results of conductivity measurement of ethanol as test solution using two point probe method is.

Abstract

This research aims to determine the impact of learning using inquiry strategies assisted by academic blogs on the 21st century skills of students in the Physics Education Study Program at IKIP PGRI Pontianak. This research is a pre-experimental design research with a One group pretest-posttest design. The sample used was all 18 fifth semester students. The data collection technique is to determine conceptual abilities using tests, while to determine 21st century skills, namely 4C skills (Critical Thinking, Communication, Collaboration and Creativity) using observation techniques. The data collection tools used were test questions and observation sheets. Based on data analysis, it is known that there is a significant increase in students' understanding of concepts before and after learning in the high category. Students master 21st century skills, namely critical thinking, communication, collaboration, and creativity in the high category in every lesson. The academic blog-based inquiry learning model is innovative in improving the quality of physics learning in the 21st century educational era.
