Abstract

Artikel ini mengkaji minat belajar pada tingkat sekolah dasar dengan fokus pada materi pembelajaran, faktor-faktor yang memengaruhi peningkatan prestasi siswa, serta teknik untuk meningkatkan minat belajar. Dengan menggunakan metode analisis naratif dan deskriptif kualitatif, penelitian ini menyoroti peran penting proses pembelajaran terhadap hasil belajar. Hasilnya menunjukkan bahwa faktor seperti peran guru, sumber belajar, lingkungan keluarga, dan lingkungan sekolah berkontribusi pada minat belajar siswa. Rekomendasi yang diberikan mencakup pemahaman terhadap tujuan pembelajaran siswa, penggunaan insentif, pendorong motivasi, bantuan saat belajar, dan pemanfaatan media yang sesuai. Disarankan agar para guru menerapkan temuan ini dalam praktik pembelajaran di sekolah dasar.

Abstract

Pengembangan Media Flashcard memliki tujuan untuk mengetahui bagaimana kelayakan, kepraktisan, keefektivan, dari produk yang tekah diiciptakan yaitu media Flashcard pada pembelajaran Bahasa Inggris. Jenis penelitian yang digunakan yaitu Research and Delopment (RnD) dengan model pengembangan ADDIE ( Analyse, Design, Development, Implementation, Evaluation). Subjek penelitian ini adalah ahli materi, ahli media guru dan siswa kelas V SD Swasta PAB 27 Medan dengan jumlah 28 orang siswa, yang terdiri dari 12 laki-laki dan 16 orang perempuan. Teknik pengumpulan data yang digunakan adalah dengan analisis data kuantitatif dan kualitatif. Adapun hasil penilaian dari produk yang telah dikembangkan dengan kelayakan materi sebesar 82% dan kelayakan dari media sebesar 88% dengan katergori “Sangat Layak”. Pratikalitas yang diuji bersama dengan wali kelas V mendapat presentasi kepraktisan sebesar 95%. Pada keefektivan produk yang diciptakan sebesar 92% keduanya dengan kategori “Sangat Layak”. Dari hasil penelitian yang dilakukan, maka dapat disimpulkan produk Flashcard yang telah dikembangkan sangat layak, sangat praktis, dan sangat efektif untuk diberikan kepada peserta didik khususnya pada pembelajaran Bahasa Inggris

Abstract

The transfection efficiency positively affects the successful plasmid DNA transfer into cells, with the highlight on the amount of plasmid DNA and its ratio to the transfection reagent. Polyethyleneimine (PEI) is a cost-effective transfection reagent that facilitates DNA transfer by forming positively charged DNA complexes. It allows DNA to interact with negatively charged cell surfaces and enter the cells by endocytosis. In this study, we optimized the condition for transient transfection of life act-GFP/NLS-mCherry-expressing plasmid in BHK-21 and 293T cells using PEI. This plasmid is helpful as a biosensor of the cytoskeleton and nucleus that enables live imaging observation using a fluorescence microscope, for instance, in the observation of syncytium. Here, we optimized two independent variables: the amount of DNA (0.5 and 1 µg) and the ratio of DNA-PEI (1:3 and 1:4). GFP and mCherry expressions were observed at 24, 48, and 72 h post-transfection. As a result, transfection efficiency achieved by using PEI in 293T cells is higher than in BHK-21 cells, which are ~90% and ~50%, respectively. Moreover, amongst four different transfection conditions, in both cell lines, 1 µg of plasmid DNA with a 1:3 DNA-PEI ratio yields the most efficiency with the least amount of toxicity. We used this condition for the syncytia observation in 293T cells as a model of the cell-to-cell transmission of SARS-CoV-2. Syncytia formation was successfully observed by detecting the giant cells expressing GFP/mCherry with multiple nuclei.

Abstract

The moderating variable in this study is firm size. The study aims to determine the effects of net profit margin, debt-to-debt equity ratio, and total asset turnover on stock prices. This study falls under the category of quantitative research and employs a descriptive and verification technique. Secondary data were used; the procedures for gathering the data were provided by documentation and a review of the literature. In the sampling process, purposeful sampling is employed. The data analysis techniques used in this study included modified regression analysis (MRA), coefficient of determination analysis, product-moment correlation coefficient analysis, multiple regression analysis, and the classical assumption test. According to the results of the simultaneous test (F test), the debt-to-equity ratio, net profit margin, and total asset turnover all influence stock prices concurrently. The correlation criterion table shows that the correlation score is between 41% and 60%, which indicates a moderate connection. This indicates that, beyond the variables analysed, there exist additional factors that have the potential to increase the share prices of mining companies in the coal subsector on the Indonesia Stock Exchange between 2015 and 2022.
