Abstract

Staphylocococcus aureus dalam beberapa kasus berpotensi menyebabkan infeksi pada kulit dan jaringan internal sehingga memicu penyakit sistemik yang berbahaya bagi manusia. Saat ini terapi pengobatan infeksi akibat S. aureus dilakukan menggunakan antibiotik. Tetapi penggunaan antibiotik seringkali menyebabkan masalah resistensi dan menimbulkan fenomena MRSA atau Methicillin-Resistant S.aureus.Oleh sebab itu perlu dilakukan upaya pencarian bahan alam alternatif yang berpotensi sebagai antibakteri. Salah satunya adalah jeruk lemon (Citrus limon). Tujuan penelitian ini adalah mengetahui gambaran skrining fitokimia dan mengevaluasi kembali kemampuan aktivitas antibakteri ekstrak etanol kulit buah jeruk lemon terhadap pertumbuhan S. aureus dengan konsentrasi 20%,40%,60%,80%, dan 100%. Desain penelitian ini adalah eksperimental dengan sampel penelitian berupa kulit buah jeruk lemon sebanyak 10 kg dari Pasar Bantar Gebang, Bekasi, Jawa Barat. Prosedur penelitian ini meliputi penyiapan sampel, ekstraksi dengan metode masertasi, skrining fitokimia secara kualitatif, dan uji senyawa antibakteri ekstrak etanol kulit buah jeruk lemon 20%, 40%, 60%, 80%, dan 100% dengan metode Kirby Baeur. Pada penelitian digunakan kontrol positif berupa antibiotic vankomisin 30 µg dan kontrol negatif berupa aquades steril. Analisis data dilakukan dengan pendekatan deskriptif kuantitatif. Hasil rendeman ekstrak kental etanol kulit buah jeruk lemon menghasilkan warna cokelat kekuningan dengan bau khas aromatik. Uji skrining fitokimia ekstrak etanol kulit buah jeruk lemon menunjukkan positif tanin, fenolik (fenol), flavonoid, saponin, terpenoid, dan negatif alkaloid. Adapun pemberian ekstrak etanol kulit buah lemon dengan konsentrasi 20%, 40%, 60%, 80%, 100% mampu menghambat S.aureus dengan diameter zona hambat secara berurutan sebesar 1.5 mm, 1.8 mm, 2.3 mm, 2.8 mm, dan 3.5 mm dengan kategori resisten. Kesimpulan dari penelitian ini adalah pemberian ekstrak etanol kulit buah lemon tidak efektif dalam menghambat pertumbuhan S.aureus.

Abstract

The study aims to investigate the importance of infusing SSI (Socioscientific Issue) into STEM (Science, Technology, Engineering, Mathematics)-based Biotechnology learning by capturing the perceptions of students in Natural Science and Social Science. This is intended to make learning more effective because it helps students to achieve the comprehension of the material being taught. The research apply mix methods by capturing quantitative and qualitative data. The quantitative data are collected from the percentage of answers from 291 students who have filled out quizzes through online surveys. While qualitative data is collected from garnering students’ answers through unstructured interviews. The results showed that students of Natural Science discussed biotechnology more technically and normatively resulting in product effects, while students of Social Science focused more on the policy and risk aspects of biotech products. It is the difference in perception between the two majors that requires the SSI approach to be infused into the STEM approach. The benefits of such infusionare improved students' HOTS (Higher Order Thinking Skills), which is in line with the current learning trend of the Industrial Revolution 4.0. Keywords: SSI, Biotechnology, STEM education, HOTS

Abstract

Noemuti River is a river located in North Central Timor District. The river is used by local people for daily needs such as washing motorbikes and clothes. In addition, at some point it is also used to mine sand. Seeing this phenomenon, it is estimated that there has been a change in the plankton community in the river, so it is necessary to conduct research on the plankton community in the river. This research was conducted by purposive random sampling to take existing plankton samples to see their abundance, diversity, dominance and evenness using index calculations. Based on research that has been done, the Noemuti River has an abundance of plankton 11400, 8716 and 7241 cells/L. The diversity index is 2.362; 2,627; and 2,880. Dominance index 0.173; 0.121 and 0.071 and the evenness index is 0.753; 0.838 and 0.918 this shows that the Noemuti River has a moderate and relatively even distribution of plankton diversity. So it can be concluded, that activities around the Noemuti river do not really affect the existing plankton community.
