The understanding of students' concepts of SMP Negeri 1 Kandangan on the material of the skeletal system is still low. This study aims to determine the effect of applying Android-based Augmented Reality laboratory coats to students with different academic abilities on understanding the concept of skeletal system material for students of SMP Negeri 1 Kandangan. This research is a quasi-experiment or quasi-experiment with a pretest-posttest control group design. The population used in this study were all seventh-grade students of SMP Negeri 1 Kandangan. In contrast, the samples in this study were class VII A as the control class and class VII B as the experimental class, which would be treated as applying an Augmented Reality Android-based. The sample was determined using a purposive side technique. The ANCOVA test results show a significant difference in student's conceptual understanding of the skeletal system material between the control and the experimental, with a significance value or p of 0.006, which is

This study aims to determine the effectiveness of the Project-Based Learning model conducted via online (e-PjBL) on the concept understanding of evaluation in the biology learning. A quasi-experimental method with a non-equivalent pre-test and post-test group design is chosen in this study. The research is carried out at the Biology Education Study Program of Universitas Tidar in March - June 2021. A total of 63 college students become the sample in this research which are divided into experimental class and control class. The instrument used to collect the data is in the form of a concept understanding test about the evaluation of biology learning. Then, the results of the data are analyzed by quantitative. The results show that there is no difference in the use of online Project-Based Learning models on the concept understanding of evaluation in biology learning. This is indicated by the results of hypothesis test which is 0.184 > 0.05. Meanwhile, the average N-Gain in the experimental class is 0.2083 which belongs to the ineffective category. Next, several factors become obstacles to the online Project-Based Learning that causes this learning model to be ineffective.

This research aims to improve the motivation and student scientific writing skill (SCWS) by applying the integration of Simas eric and Blended learning models. This study is a classroom action research method conducted in one of the classes in the biology education program for the National student scientific week (PIMNAS) project of biology education Program, Universitas Tidar. The results of the study were analyzed descriptively. The results showed an increase in students’ motivation and learning outcomes. Students’ learning motivation on average increased by 10.59% and SCWS on average increased by 33.28%. The results of this study can be an alternative reference for lecturers or educators as an effort to improve student learning motivation so that the learning outcomes obtained can increase. Therefore, the integration of Simas eric with google classroom can enhance students’ motivation and SCWS Subjects at the biology students.
