Abstract

This study aims to develop and see the effect of website-based learning media on improving student learning outcomes. The population of this research is all students of grade XI of SMA Panca Budi Medan. Samples were taken by simple random sampling of two classes consisting of experimental class 1 which was taught using website-based media with a problem based learning model and experimental class 2 which was taught using power point media with direct instruction model. Based on the results of data analysis, website-based learning media that have been made have met the eligibility standard with a score of 3.71 out of 4,00 with valid criteria and do not need to be revised. Based on the results of the t test, the tcount data (2.44) is greater than ttable, so the hypothesis can be accepted.. So it can be concluded that the website-based learning media on the chemical equilibrium material made has met the website's eligibility standards; Student learning outcomes using website-based learning media with problem based learning models are higher than student learning outcomes using power point learning media with direct instruction models.

Abstract

This study aims to determine differences in students' critical thinking using the Problem Based Learning (PBL) and Guided Inquiry learning models on electrolyte and non-electrolyte solutions. This research was conducted at SMAN 17 Medan in the 2022/2023 academic year. This type of research is a quasi-experimental research design with a pretest-posttest control group design. The population in this study were all students of class X IPA SMA Negeri 17 Medan. The sample of this study was class X IPA 5 as the experimental class I which was taught using the Problem Based Learning model and X IPA 6 as the experimental class II which was taught using the Guided Inquiry learning model. The results of this study indicate that there are differences in learning outcomes between the two classes with an average posttest score of students in experimental class I of 74 and an average posttest score of students in experimental class II of 82. The ability to think critically in experimental class I is prominent/dominant in analytical skills. The ability to think critically in experiment II is dominant in the ability to argue, evaluate and conclude.

Abstract

Penelitian ini bertujuan untuk menganalisis persepsi mahasiswa jurusan matematika pada kelas kimia umum terhadap manfaat jamu bagi kesehatan di Universitas Negeri Medan (UNIMED). Penelitian deskriptif kuantitatif ini melibatkan 40 responden mahasiswa matematika yang dipilih melalui teknik purposive sampling. Pengumpulan data dilakukan menggunakan kuesioner yang terdiri dari 20 pernyataan mencakup aspek pengetahuan (12 item), kepedulian lingkungan (4 item), dan psikomotor (4 item). Hasil penelitian menunjukkan bahwa mayoritas mahasiswa matematika (76,5%) memiliki persepsi positif terhadap manfaat jamu bagi kesehatan, dengan nilai reliabilitas kuesioner sangat tinggi (Cronbach's Alpha = 0,9053). Dari 20 item pernyataan, 17 item (85%) dinyatakan valid dengan nilai korelasi (r) > 0,3 dan p-value < 0,05. Dimensi kognitif menunjukkan reliabilitas tinggi (α = 0,8673), dimensi afektif dapat diterima (α = 0,7620), dan dimensi perilaku tinggi (α = 0,8066). Namun, terdapat kesenjangan antara persepsi positif dengan perilaku aktual mengonsumsi jamu secara rutin. Penelitian ini merekomendasikan penguatan edukasi tentang jamu sebagai warisan budaya dan alternatif kesehatan di kalangan mahasiswa, serta perlunya penelitian lanjutan untuk menganalisis faktor-faktor yang mempengaruhi perilaku konsumsi jamu.
