Abstract

Basic Engineering Mechanics is a science that plays an important role in civil engineering disciplines, especially in the construction sector. In studying Basic Engineering Mechanics, a Project Based Learning model is needed that can help students to more easily apply it. This study aims to determine the increasing in learning outcomes of Basic Engineering Mechanics of Civil Engineering Study Program students through the application of Project Based Learning model. The type of research to be conducted is experimental research using the pretest-posttest control group design. The research subjects were students of the Civil Engineering Study Program, Graha Nusantara University, Padangsidimpuan for first semester in Academic Year 2021-2022, totaling 60 people. Research instrument in the form of pre-test and post-test. The data analysis technique used in this research is comparative descriptive analysis, while the increasing in student learning outcomes through the application of Project Based Learning (PjBL) model is calculated using g-factor (normalized gain score). Based on the research results obtained, it can be concluded that the Project Based Learning model can increase the learning outcomes of Basic Engineering Mechanics for Civil Engineering Study Program students by 37.74%. While the conventional learning model can only increase the learning outcomes of Basic Engineering Mechanics for Civil Engineering Study Program students by 31.41%. So that the Project Based Learning model is more effectively used in Basic Engineering Mechanics courses than conventional learning model.

Abstract

Learning by using scientific articles allows students to deepen the concepts they have learned. The purpose of this study was to determine the use of scientific articles in basic chemistry learning in universities and students' perceptions of the learning used, especially the stoichiometric concept which is the main concept in studying chemical calculations. This research was conducted with an experimental method using the One Group Pretest-Posttest Research Design. Research instruments in the form of tests and questionnaires. Learning outcomes data were analyzed using the Wilcoxon test and N-gain. Meanwhile, the students' perceptions and commitments to learning were analyzed using a Likert scale. Based on the results of the study, it can be shown that the use of scientific articles can improve student learning outcomes in learning basic chemistry. Students' perceptions and commitment to learning with scientific articles gave positive results. This can be seen from the average results of the perception and commitment questionnaire assessments of students, each of which is in the medium category. Thus, the use of scientific articles is very suitable to be applied in learning basic chemistry.Belajar dari artikel ilmiah memungkinkan mahasiswa untuk memperdalam konsep yang telah dipelajarinya. Tujuan dari penelitian ini adalah untuk mengetahui penggunaan artikel ilmiah dalam pembelajaran kimia dasar di perguruan tinggi dan persepsi mahasiswa terhadap pembelajaran yang digunakan, khususnya konsep stoikiometri yang merupakan konsep utama dalam pembelajaran perhitungan kimia. Penelitian ini dilakukan secara eksperimental dengan menggunakan rancangan penelitian one-group pretest-posttest design. Instrumen penelitian berupa tes dan angket. Data hasil belajar dianalisis menggunakan uji Wilcoxon dan N-Gain. Sedangkan persepsi dan keterlibatan mahasiswa dianalisis menggunakan skala Likert. Berdasarkan hasil penelitian ini menunjukkan bahwa penggunaan artikel ilmiah meningkatkan hasil belajar mahasiswa pada saat pembelajaran kimia dasar. Persepsi dan keterlibatan mahasiswa dalam pembelajaran dengan artikel ilmiah memperoleh hasil yang positif. Hal ini terlihat dari rata-rata nilai mahasiswa pada angket persepsi dan keterlibatan mahasiswa, keduanya berada pada kategori sedang. Oleh karena itu, penggunaan artikel ilmiah sangat cocok diterapkan pada kajian kimia dasar.

Abstract

The Aptitude-Treatment Interaction (ATI) learning model is a learning model that has a number of strategies (treatments) used to deal with each particular individual according to their respective ability levels in order to improve student learning outcomes. This study aims to determine the effect of the application of the ATI learning model on student learning outcomes in science learning and to determine the effectiveness of the ATI learning model in science learning. The sample of students studied were students of the Civil Engineering Study Program, Faculty of Engineering, Graha Nusantara University, which consisted of 2 groups. The first group was used as the experimental group (teaching with ATI) and the second group as the control group (teaching without ATI) with the number of students in each group = 20 people. The research design used was a 2x2 quasi-factorial experimental design. The data obtained were analyzed by chi-square test at a significance level of 0.05. The results showed that the experimental group's science learning outcomes increased by 49.17%, while the control group's science learning outcomes only increased by 42.25%. Thus, the ATI learning model has an effectiveness percentage of 1.67%. With the chi-square test, it can be stated that this effectiveness is due to the influence of the application of the ATI learning model.

Abstract

The success of students in mastering the subject matter of Basic Mathematics can be seen from the results of learning Basic Mathematics. One of the learning models that can activate students and improve learning outcomes in Basic Mathematics is the Team Games Tournament (TGT) learning model. This study aims to determine the effect of the Team Games Tournament (TGT) learning model on the learning outcomes of Basic Mathematics students of the Civil Engineering Study Program and to prove that the Team Games Tournament (TGT) learning model is able to improve learning outcomes of Basic Mathematics students of the Civil Engineering Study Program. This research was conducted through Classroom Action Research (CAR) with a research sample of 40 people. The design used in this study was a pretest-posttest control group design. Based on the research results obtained, it can be concluded that the results of the t-test hypothesis test indicate that tcount ≥ ttable or 14.6551≥ 2.023. This means that Ho is rejected or Ha is accepted. So that the Team Games Tournament (TGT) learning model affects the learning outcomes of Basic Mathematics students of the Civil Engineering Study Program, Universitas Graha Nusantara Padangsidimpuan. Through the application of the Team Games Tournament (TGT) learning model, it is proven that the learning outcomes of Basic Mathematics students of the Civil Engineering Study Program at Graha Nusantara University Padangsidimpuan increased by 48.75% with a percentage effectiveness of 7.14%.
