Abstract

The effectiveness of using Indonesian as a means of communication and providing information. Good Indonesian is words that are suitable for communicating effectively. With language, a person can express ideas, ideas, thoughts and desires in conveying an opinion. Which aims to improve how to speak Indonesian properly and correctly. The application of Indonesian in daily life can be used as a weapon to develop an attitude of nationalism and unify all people in Indonesia. This research used qualitative methods by conducting interviews with students of the Biology Department, Medan State University. From the results of interviews with students from the Biology Department, Medan State University, it was said that students used good and correct Indonesian when together with lecturers, but outside of lectures, students from the Biology Department at Medan State University used current slang and their regional language. Therefore, we need to apply good and correct use and understanding of Indonesian every day so that Indonesian is not replaced by Modern language which is now very popular with young people.

Abstract

This study aims to examine the use of medicinal plants by the community based on local knowledge that has been passed down from generation to generation. An ethnobotanical approach is used to explore information about the types of medicinal plants, the parts of the plants that are used, how to process them, and the types of diseases that can be treated. Data were collected through literature studies of books, scientific journals, research reports, and other related documents. The results of the study indicate that the community is still very dependent on medicinal plants in their daily medical practices. Various types of plants were found to be used to treat mild to chronic diseases, with processing methods such as boiling, pounding, or brewing. These findings emphasize the importance of preserving local knowledge and conserving medicinal plants as part of a cultural heritage that has great potential in the development of alternative medicine.

Abstract

Demam Berdarah Dengue (DBD) tetap menjadi masalah serius karena resistensi nyamuk Aedes aegypti terhadap insektisida kimia. Nanopartikel perak berbasis biosintesis ramah lingkungan kini dikembangkan sebagai alternatif, dengan daun melinjo yang mengandung metabolit sekunder berpotensi digunakan sebagai pereduksi AgNO₃. Pemanfaatan spesies ini belum pernah dilaporkan sebelumnya. Penelitian ini bertujuan mensintesis nanopartikel perak (AgNP) secara biologis menggunakan ekstrak daun melinjo (Gnetum gnemon) dan mengetahui potensinya sebagai larvasida. Biosintesis dilakukan dengan mereduksi larutan AgNO₃ 1 mM menggunakan ekstrak melinjo (1:30) pada pH 10. AgNP ditandai dengan perubahan warna larutan menjadi kekuningan hingga coklat. Hasil karakterisasi UV-Vis menunjukkan puncak serapan bergeser dari 398 nm menjadi 421,13 nm setelah 24 jam. Analisis SEM memperlihatkan partikel berbentuk bulat, pentagon dan heksagon yang berukuran 37,654 sampai dengan 877,131 nm, sedangkan FTIR mengidentifikasi gugus fungsi O–H, C≡C, dan C=O yang berperan dalam reduksi ion perak. Uji aktivitas larvasida terhadap larva A. aegypti menghasilkan nilai LC₅₀ sebesar 18.513 ppm yang termasuk kategori sangat toksik. Hasil menunjukkan bahwa daun melinjo berpotensi dalam mensintesis AgNO₃ menjadi AgNO0, serta hasil sintesis dapat dimanfaatkan sebagai larvasida. Temuan ini memberikan kontribusi pada pengembangan ilmu pengetahuan dengan menambah informasi tentang biosintesis nanopartikel perak (AgNP) menggunakan ekstrak daun melinjo (G. gnemon). Dari segi kesehatan masyarakat, penelitian ini memberikan alternatif pengendalian nyamuk A. aegypti yang lebih efektif dan berpotensi mengurangi risiko resistensi nyamuk terhadap insektisida kimia.
