Abstract

Teaching and learning activities not only require students to obtain good cognitive learning outcomes but also require students to be able to play an active role in learning so that students have good attitudes and skills as well. Student activeness can be seen from the activities or activities during learning. Therefore, this study aims to determine the increase in student learning activities and student learning outcomes using the Inquiry Training learning model. This type of research is a quasi experiment. The instrument used was the observation sheet in accordance with the learning model applied and the learning outcome test in the form of an essay totaling 10 items. The results showed that an increase in student learning activities would affect the achievement of student learning outcomes.

Abstract

Teaching and learning activities that tend to be monotonous and passive result in low student interest in learning and achievement. Therefore, this study aims to determine the collaboration and achievement of student motivation in learning physics. This research is applied with the cooperative learning model Group Investigation (GI) type in six phases that can improve collaboration, motivation and student achievement, namely selecting topics, cooperative planning, implementation, analysis and synthesis, presentation, evaluation. This type of research is a quasi experiment. The instrument used was a test of student learning outcomes in the form of descriptions totaling 10 items and student activity sheets, namely experimental activities. The results showed that the existence of good peer collaboration will affect the achievement of student motivation in learning physics.

Abstract

Constructivistic LKPD is a worksheet designed to give students the opportunity to express the ideas they have so as to encourage students to expand their knowledge regarding the problems given. This study aims to analyze how the students' conceptual knowledge using the constructivist student worksheets applied to the group investigation model. This research was conducted at SMA Dharma Pancasila Medan, this research is a quasi-experimental study where the sampling was carried out using purposive sampling, namely the sampling in the study was taken by consideration or certain criteria. The application of constructivist LKPD in the group investigation model was at the investigative stage. During the process of the investigation stage, a student skills assessment was carried out which consisted of seven indicators. The results of the student skills assessment showed a significant change in students' conceptual knowledge.

Abstract

This study aims to produce physics learning media for class XI high school on the subject matter of optical devices based on android using the MIT app inventor. This research is a Research and Development study using the 4D (Define, Design, Develop and Disseminate) method which starts with the creation of a .apk format-based installer program on the MIT App Inventor website. This program can be used easily by beginners. The user does not need to write or remember instructions because the user only chooses and organizes the choices available on the website so that the user easily develops the application by finding the appropriate blocks. Validity Testing on featured and content in the program is done by experts. Products are revised according to the team's recommendations until the product is feasible to be tested on students. The feasibility and response of the use of the program are done by the teacher, then tested on 10 students in small group trials and 30 students in large group trials. The research results obtained from validation that the program has been declared valid and can be used as a medium for learning physics. Based on the validation test obtained a percentage of features by 97,7% and the percentage of content by 94,95%. The feasibility of an Android-based learning program using the inventor app on material optical equipment by physics subject teachers based on teacher responses of 3.725 and learners of 3.765 in the feasible category. Based on the trial data, the product has been declared suitable for use by teachers and students as a medium of learning in schools and as a medium of independent learning.

Abstract

This study aims to determine the effect of the composition comparison of the PVA-Enzyme urease coating PVC-Plastisizer KTpClPB membrane with memmbran characterization using FTIR and analyze membrane electrodes with XRD. The method used is the potentiometric method using the Electrode Selective Ion (ISE), where the polymer used is PVA and PVC as a coating with a composition ratio of PVA: PVC is 1: 1. The same PVA and PVC were used, namely 0.0350 g, with 2 mg of enzyme and 0.0500 g and 0.0120 g of KTpClPB plasticizer. The best composition result is the PVA-Enzyme PVC-Plastisizer coating enzyme KTpClPB 0.0500 g membrane electrode characterization using XRD shows the highest intensity value is at an angle of 2θ = 44.020 which is 1,626 count second (cts) and membrane characterization using FTIR shows that there is a functional group OH, CH, C≡C, NH, CO and CH. The addition of PVA-Enzyme coating will reduce or even eliminate the amount of Wolframm and can reduce the amorphous properties of the membrane electrodes.
