Abstract

This article aims to determine the relationship between offline learning and interest in learning discrete mathematics after the pandemic. The research method used is quantitative. The sampling technique in this study used purposive sampling. Data collection in this study used a questionnaire with a Likert scale of 1 to 5. The variables in this study consisted of variable X, namely offline learning and variable Y, namely interest in learning. Each variable consists of 4 indicators. The result of this research is that there is a relationship between offline learning and students' interest in learning in discrete mathematics courses of 0.801. So it can be said that the relationship between offline learning and learning interest is very strong. This is because in offline learning students can interact directly with the lecturer so that discrete mathematics material that has not been understood can be directly asked during learning. Offline learning can also encourage interest in learning so that students are more enthusiastic and enthusiastic about participating in discrete mathematics lectures.

Abstract

This study aims to improve the problem solving ability of class VIII junior high school students. This research was conducted after the preliminary study it was found that problem solving abilities were still relatively low. Observational shows that more than 50% of class VIII students of SMP Muhammadiyah 3 Depok have poor problem solving skills. Based on the theory put forward some expert of experts, the researchers decided to apply the problem-based learning model. This study uses classroom action research design with a target of 50% of students having a problem solving ability score above the Kriteria Ketuntasan Minimal (KKM). There are four stage of this research, namely planning, implementation, observation and reflection. The data collection technique using the test and non-test techniques. Data analysis using descriptive analysis of quantitative and qualitative analysis descriptive. From the results of the study, it was found that 77% of students had problem solving scores above the KKM. Besides that, it was found that student were able to work on the questions in a more structured manner and could better understand the questions given.

Abstract

The purpose of this study was to determine the effect of mathematical logical intelligence on student learning outcomes in Linear Algebra courses. The research method used is quantitative. The sampling technique used in this study was simple random sampling. Data collection in this study used a mathematical logical intelligence test of 20 multiple choice questions and a test of student learning outcomes in linear algebra courses of 5 description questions. The variables in this study consisted of independent variables and dependent variables. The independent variable in this study is mathematical logical intelligence (X), while the dependent variable in this study is student learning outcomes in Linear Algebra courses (Y). The instrument test in this study consisted of validity test, distinguishing power, difficulty level and reliability test. The classical assumption test in this study consists of normality test and linearity test. The data analysis technique used simple linear regression. The result of this study is that there is an influence between mathematical logical intelligence on student learning outcomes in linear algebra courses of 0.527 or 53%. While the other 47% is influenced by other variables outside this study.

Abstract

Indonesia merupakan negara agraris dengan produksi padi yang besar, dimana limbah sekam padi yang melimpah dapat dimanfaatkan sebagai bahan baku pembuatan furfural. Penelitian ini bertujuan untuk menganalisa kondisi optimum pengaruh besar ukuran bahan, suhu reaksi dan jenis katalisator asam dengan persen berat yang sama 9% terhadap kadar furfural yang dihasilkan. Penelitian dilakukan mulai hidrolisis sekam padi (50-80, 80- 100, 100 mesh) dengan beberapa jenis katalisa H2SO4, HCl, HNO3(9%) pada kondisi suhu 60oC, 80 oC, 105oC. Selanjutnya analisa kualitatif dengan anilin asetat, analisa kuantitaf yield furfural dengan volumetric, Spektrofotometer FTIR. Metode penelitian untuk menentukan kondisi paling efisien dalam menghasilkan furfural menggunakan metode Response Surface Methodology (RSM) Box Behnken dengan Software Design Expetr @9. Perolehan kondisi optimum yaitu ukuran bahan 90-100 mesh, suhu reaksi ≤ 90 °C, reaksi pada level tersebut didapatkan yield furfural ± 0,7%. Kata Kunci : Sekam padi, furfural, hidrolis, RSM Box Behnken, FTIR
