Abstract

Online learning is very effective and efficient during the current Covid-19 pandemic. Through this online learning, students can still carry out lectures without having to face to face with the lecturer. The purpose of this study was to determine the effect of online learning on the interest and learning outcomes of Basic Chemistry students of the Civil Engineering Study Program. The research samples were first semester students of the Civil Engineering Study Program, Graha Nusantara University, Padangsidimpuan, Academic Year 2020/2021 who took online learning during the Covid-19 pandemic, with a total of 40 respondents. The research method used to determine the effect of online learning on students' interest and learning outcomes was carried out using qualitative and quantitative research methods. Based on the Pearson Product Moment Correlation test, rcount> rtable or 4.401 > 0.2573 which means that H1 is accepted and Ho is rejected. So that online learning has an effect on interest in learning Basic Chemistry for first semester students of Civil Engineering Study Program, Graha Nusantara University, Padangsidimpuan, Academic Year 2020/2021. Based on the t-test conducted, it is found that tcount ≥ ttable is 6.22 ≥ 2.023, which means Ho is rejected or H1 is accepted. Thus, online learning also affects the learning outcomes of Basic Chemistry of first semester students of Civil Engineering Study Program, Graha Nusantara University, Padangsidimpuan, Academic Year 2020/2021.

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

The world of construction is progressing very rapidly. The higher the need for infrastructure development, the energy absorption to support these activities will certainly be very large. To minimize this need, it is necessary to have innovations that can reduce the production of materials, such as cement. Therefore, it is necessary to have an alternative to take advantage of wasted waste such as egg shells to be used as a partial or complete substitute for cement, especially as a mixed material in the manufacture of concrete. This study aims to maximize the use of chicken egg shell waste for concrete mixtures. Egg shell powder to be added as a partial substitute for cement is made with a composition variation of 0%; 2.5%; 5%; 7.5%; 10%. Where each variation is made into 3 samples, so that the total sample is 15 samples and the compressive strength of the concrete is tested after 28 days. Based on the results obtained, it can be concluded that the mixture of concrete with egg shells at a percentage of 2.5% is called the optimum state. The optimum condition is a condition where the compressive strength of the resulting concrete is greater and maximum when used to make environmentally friendly concrete.
