Abstract

Penelitian ini menganalisis pengaruh LKS pada kemampuan berfikir kritis siswa pada pembelajaran fisika yang ditentukan melalui effect size yang diperoleh dari 20 artikel nasional yang terakreditasi. Analisis didasarkan pada materi pokok pembelajaran, pendekatan pembelajaran, dan model pembelajaran yang digunakan dalam LKS. Hasil penelitian menunjukan bahwa berdasarkan materi pokok, pendekatan dan model pembelajaran menggunakan LKS memiliki pengaruh yang sedang hingga tinggi terhadap keterampilan berpikir kritis siswa. Pengaruh yang paling tinggi menurut hasil data effect size adalah  pada materi Alat-alat optik, Gelombang Suara, Usaha dan energi ,dan  Fisika SMA. Pada model yang digunakan dalam LKS yang miliki pengaruh paling tinggi menggunakan model Guide Inquiry Learning. Sedangkan berdasarkan pendekatan pembelajaran LKS, pengaruh yang paling tinggi menurut hasil data effect size adalah pendekatan menggunakan STEM  terhadap peningkatan keterampilan berpikir kritis siswa.

Abstract

Profil kesehatan Indonesia tahun 2019 menunjukkan bahwa negara Indonesia masih menghadapi peningkatan angka penyakit diare sebesar 270 per 1.000 penduduk, dengan prevalensi yang lebih tinggi pada anak di bawah usia lima tahun. Metode yang digunakan adalah systematic riview dengan mengumpulkan artikel jurnal penelitian dari dari situs Google Scholar, Semantic Scholar, dan research gate. Hasil Review dari 11 literatur jurnal disimpulkan bahwa pengetahuan masyarakat di Indonesia tentang swamedikasi diare umumnya cukup, dipengaruhi oleh faktor-faktor seperti karakteristik demografi, sosioekonomi, dan lingkungan. Tingkat pengetahuan yang baik atau rendah dapat mempengaruhi perilaku swamedikasi diare, yang tercermin dalam analisis perilaku masyarakat. Faktor lingkungan seperti jenis air minum dan kebiasaan perilaku, termasuk mencuci tangan, juga memengaruhi kejadian diare di Indonesia. Penggunaan obat dalam swamedikasi diare perlu dipantau lebih lanjut oleh tenaga kesehatan, mengingat masih adanya penggunaan obat tradisional yang cukup tinggi di masyarakat.

Abstract

The challenge of education in meeting the needs of the internet generation is quite big. This is due to their different life experience of his special experience in using technology. The Internet itself opens up many possibilities for integrating technology into classroom learning. Youtube is one of the learning media that can be integrated with learning subjects that are considered difficult by students. The purpose of this study is to see how far Youtube can be used as a medium of learning in English subjects at Wiralodra University. This study uses a qualitative approach. In the process of collecting data for this study, researchers contacted EFL teachers and EFL students via email to be interviewed in a study interview. The results of the study show that students have a positive perception of using YouTube as a teaching medium in the English language education study program at Wiralodra University, especially in the listening class because the videos they present can be played repeatedly, are easy to use, and easy to access. In addition, they can get so much material for their lectures.

Abstract

Natural dyes extracted from butterfly pea flowers (Clitoria ternatea L.) hold significant potential as alternatives to synthetic dyes in the food and textile industries. This study aims to evaluate the effectiveness of citric acid isolated from bilimbi (Averrhoa bilimbi L.) as a solvent for extracting anthocyanin pigments from butterfly pea flowers. Ultrasonic extraction was conducted using different solvents (citric acid and ethanol) and varying extraction durations. The results showed that the extract yield ranged from 2.6% to 5.5%, with an average of 3.99%. Ethanol produced a higher yield than citric acid; however, citric acid significantly reduced the extract’s pH to a range of 1–6, potentially enhancing anthocyanin pigment stability. Additionally, extraction time positively influenced yield up to an optimal point, after which degradation of active compounds led to a decline. These findings suggest that bilimbi-derived citric acid has potential as an eco-friendly solvent for natural dye production, though further optimization is needed to enhance extraction efficiency and color stability.
