Abstract

It has been claimed that an Indonesian seaweed lipid extract possesses antibacterial properties. The mitochondrial pathway reported that a long fatty acid (more than 10 carbon atoms), which is known as the major component in seaweed lipid extract, acts as an apoptotic agent. It has also been claimed that unsaturated fatty acids can prevent apoptosis. on this study, we investigated the role of an Indonesian seaweed lipid extract on the mitochondrial pathway of apoptosis. Lipid isolation was the first step of the study, which was carried out using centrifugation and a chloroform-methanol-phosphate buffer 2:1:0,8. Rotary evaporators were used to separate the lipid extract from its solvent. Dry weight Gracilaria sp. yield extraction was 21,8%. By using several centrifugation techniques in SET buffer (0,25 M Sucrose, 0,5 mmol EDTA, and 10 mmol/L Tris base), pH 7,4, mitochondria were recovered from rat liver. By adding 10% (v/v) lipid extract to a suspension of mitochondria, toxicity testing from the lipid extract was undertaken. By using light microscopy, mitochondrial morphological damage was seen. Gracilaria sp. exhibits strong apoptotic activity.

Abstract

Despite the importance of scientific literacy for learning, Indonesian students typically lack adequate literacy skills. The goal of this study is to determine whether teaching methods that use live worksheets and the flipping stem class paradigm can aid students in developing their scientific literacy. A quantitative quasi-experimental research design was used for this investigation. All pupils in class XI IPA 1–5 at a high school in Serang District made up the study's population. Class XI IPA 1 served as the experimental class for this study, and class XI IPA 2 served as the control class. Pretest, posttest, and student response questionnaires were the instruments used in this study. The posttest findings revealed that the experimental class outperformed the control class in terms of average score. This is demonstrated by utilizing the t-test to assess the outcome of the final test, where the values of t-count> t-table are 5.56>2.00. The control class's N-Gain scores 0.52 in the medium category and the experiment class 0.76 in the high category. According to the results of the student response survey, learning was put to good use in 87.1% of cases. According to the research, teaching with live worksheet while having the class turn around can enhance students' reading abilities, particularly in physics classes on heat transfer materials.

Abstract

There is an increasing demand for creative ways to turn garbage into useful resources as environmental sustainability becomes more and more of a global concern. Carbon dots can be synthesized using organic materials, one of which is bitter melon skin. The goal of this research is to create an economical and environmentally friendly process for creating carbon dots from organic waste. The bitter melon peel synthesis process uses a bottom-up method with microwave techniques. Furthermore, c-dots were characterized using a UV-Vis spectrophotometer to determine the absorbance value and wavelength and FTIR (Fourier Transform Infra-Red) to determine the functional groups contained in the sample. The UV-Vis spectrophotometer characterization results obtained an absorbance value of 3.311 and a wavelength of 206 nm. FTIR results show the presence of O-H and C=C functional group bonds indicating that this synthesis process has been successfully carried out.Keyword: Carbon Dots, Bitter Melon Peel, Bottom-up

Abstract

Pemahaman konsep merupakan salah satu kunci dalam keberhasilan siswa belajar fisika. Dengan pemahaman konsep yang baik maka siswa dapat memecahkan permasalahan dalam soal dengan baik pula. Penelitian ini bertujuan untuk menganalisis kesulitan siswa dalam memahami percepatan sentripetal dan gaya sentripetal menggunakan dua metode berebeda dan faktor penyebab kesulitannya. Dalam hal ini peneliti menggunakan platform video YouTube sebagai media dalam mengetahu kesulitan siswa dalam memahami materi. Penelitian ini menggunakan metode kualitatif dengan desain deskriptif kualitatif. Penelitian dilakukan kepada 30 siswa kelas 11 MIPA 2 SMAN 1 Panggarangan dengan memberikan tes tertulis berupa pilihan ganda beralasan dan wawancara terhadap 10 orang siswa yang dipilih berdasarkan kategori nilai. Sebelum dilakukan wawancara, siswa diminta untuk menonton video YouTube mengenai percepatan sentripetal dan gaya sentripetal. Hasil penelitian menunjukkan bahwa kedua video tersebut belum mampu membuat siswa menjadi paham konsep dari perceatan sentripetal dan gaya sentripetal, masih banyak konsep yang belum mereka pahami seperti besaran kecepatan linear dan keceatan sudut, arah dari percepatan sentripetal dan gaya sentripetal, penurunan rumus percepatan sentripetal dan gaya sentripetal, alasan mengapa percepatan sentripetal dan gaya sentripetal mengarah ke pusat dan mengapa arah kecepatan linear menyinggung lintasan. Dari hasil tersebut dapat disimpulkan bahwa pemahaman siswa terhadap konsep gaya sentripetal dan percepatan sentripetal masih rendah. Faktor internal yang mempengaruhi terjadinya kesulitan adalah belum memahami konsep, minat belajar fisika dan kondisi fisik. adapun faktor eksternal penyebab kesulitan belajar berdasarkan hasil penelitian adalah pembelajaran daring, manajemen waktu kurang baik dan lingkungan belajar.Kata kunci: Gaya sentripetal, percepatan sentripetal, kesulitan belajar, pemahaman konsep.
