Published: March 2021

Abstract
The purpose of this study was to determine the understanding of mathematics concepts of pre-service elementary education teachers at Universitas Sultan Ageng Tirtayasa (Sultan Ageng Tirtayasa University) through augmented reality learning media. The method used in this study was a quasi-experiment with the design of one group pre-test and post-test. The instrument used in this study was a test of understanding of mathematics concepts on geometry topic in the form of 10 description tests and tested on 20 pre-service teachers (higher education students). The average result of N-gain in pre-service elementary education teachers was 0.48 in the medium category. Based on the results obtained, the use of augmented reality can be used as a learning medium for mathematical concepts. In the learning process, students can easily understand the material taught. The suggestion in this research is that further development of augmented reality media is needed at all levels of education and it needs to be tested in a larger scale in order to know its effectiveness to be used in all levels of education.

Abstract
This study aimed to explore techniques to make analysis rubrics on performance assessments based on the teaching experience of preservice teachers. The method of this study was descriptive qualitative. The random sampling technique was used to select the final semester of Biology Education Study Program students who had taken the Learning Evaluation course, Curriculum Development, Community Service Program, and Field Experience Practices. The data was collected using a closed-ended questionnaire with a Likert scale, interviews to obtain data related to students’ ability to compile an analysis rubric, and documentation to determine the suitability of the analysis of performance assessment rubrics in the sample lesson plan. The results showed that the ability of some preservice teachers to compile an analysis rubric on performance assessment was still inadequate (35. 49%). The obstacles experienced by the preservice teachers were in determining rubric criteria, compiling rubric descriptions, integrating biology-specific material with scientific work capabilities, and scoring the analysis rubric. This showed that the preservice teachers needed to have sufficient training in compiling an assessment rubric that is specific for biology material to optimize the assessment of learning performance.

AbstractThis study aimed to determine the influence of the Student Facilitator and Explaining (SFAE) learning model in terms of social skills in improving students’ mathematical representation abilities. This research employed the quasi-experiment design with an essay test and questionnaire as the research instruments. Both classes were given pretests and posttests. The data were analyzed using the two-way ANOVA with a significance level of 5%. %. The research results discovered that (1) there was an influence of the SFAE learning model in improving students’ mathematical representation ability, (2) there was an influence of high, medium, and low social skills in improving mathematical representation ability, and (3) there was no interaction between the SFAE learning model and social skills in increasing students’ mathematical representation ability. This shows that SFAE learning has an effect on increasing the representative ability of students, so it is hoped that educational institutions can use this learning in the learning process.

Abstract
Electrospinning is a simple process used for polymer fibers that have diameters ranging from micro to nanometers. The purpose of this study was to investigate the morphology and scaling law model of Polyvinylidene Fluoride/Carbon (PVDF/Carbon) fiber math. Fiber is made by variations in concentration 15% w/w (FPC1), 18% w/w (FPC2), 21% w/w (FPC3) and 24% w/w (FPC4) by adding of 2% (w / w) carbon in each solution. The electrospinning process parameters used are 10 kV voltage, needle tip distance and collector 12 cm, and flowrate 0.1 ml / hour. The results showed that the morphology of FPC1-FPC2 fibers was in the form of bead and the morphology of FPC3-FPC4 are structure free bead. The avarege diameters of FPC1, FPC2, FPC3 and FPC4 are 910 nm, 1123 nm, 1349 nm and 1506 nm, respectively. The scaling law models result R Square (R2) of the experiment was 0.9992, indicating a very linear model relationship between theory and experiment. Polyvinylidene Fluoride/Carbon (PVDF/Carbon) fiber composite will be used as water filtration.
