Abstract

ABSTRAK Antibiotik merupakan bagian penting dalam terapi infeksi bakteri  karena itu penemuan sumber antibiotik baru yang potensial sangat diperlukan untuk mengatasi masalah akibat  infeksi bakteri. Streptomyces adalah bakteri yang mampu memproduksi agen antimikroba dan banyak ditemukan di tanah pada rizosfer tanaman tingkat tinggi. Tujuan penelitian ini adalah mengetahui potensi Streptomyces dari rizosfer Familia Poaceae yang dapat menghasilkan antibiotik untuk menghambat bakteri S. aureus dan  E. coli. Isolasi Streptomyces dari rizosfer rumput kembangan (Digitaria microbachne (Presl.) Henr), rumput gajah (Pennisetum purpureum Schumach) dan alang–alang (Imperata cylindrica L) yang tumbuh dari tanah yang kering, sedikit berpasir dan tidak tergenang air. Tahap awal isolasi Streptomyces adalah pre treatment sampel tanah. Isolasi menggunakan media raffinosa-histidine agar. Isolat dipurifikasi pada media benneth agar kemudian dipindah ke media oatmeal agar untuk menumbuhkan spora. Identifikasi isolat Streptomyces dilakukan dengan pengecatan Gram. Uji potensi isolat Streptomyces dilakukan dengan metode agar block menggunakan bakteri uji S. aureus dan  E. coli ATCC 25922. Hasil isolasi diperoleh 57 isolat Streptomyces dengan warna miselium vegetatif, spora aerial dan pigmen difus yang berbeda. Dari 57 isolat diperoleh 10 isolat (17,50%) berpotensi ”sangat kuat” (diameter lebih dari 20 mm), 6 isolat (10,52%) berpotensi ”kuat” (diameter 10-20 mm) terhadap S. aureus, sedangkan terhadap E. coli ATCC 25922 diperoleh 8 isolat (14,04%) berpotensi antibiotik “sangat kuat” (20-30 mm), 11 isolat (17,54%) berpotensi ”kuat” (10-19,5 mm), dan 1 isolat (1,75%) berpotensi ”sedang” (7 mm).   Kesimpulan yang diperoleh adalah Streptomyces dapat dijadikan sebagai sumber penghasil antibiotik baru yang sangat potensial di Indonesia.   Kata Kunci:  Antibiotik, Streptomyces,  Familia Poaceae, Rizosfer

Abstract

The achievement of the seminar course is that students are expected to be able to discuss a Biology Education/Biology topic in depth and write it into a work in the form of problem solving ideas. The idea is packaged into one of Student Creativity Program/SCP (Program Kreativitas Mahasiswa/PKM) which was developed for one semester in the Biology Education Seminar course. Descriptive research was conducted in the even semester of 2017/2018 in two classes consisting of 16 and 13 students of S1 Biology Education class of 2015. The results showed that each student managed to collect the PKM script consisting of 9 scripts of PKM Penelitian (Research SCP), 9 scripts of PKM Gagasan Tertulis (Written Ideas SCP), 7 scripts of PKM Kewirausahaan (Enterpreunership SCP), 2 scripts of PKM Pengabdian pada Masyarakat (Community Service SCP), and 2 scripts of PKM Karsa Cipta (Creative Work SCP). The topics of the collected PKM consists of 3 scripts on biology education topics, 23 scripts on biology topics, and 3 scripts on neither biology nor biology education topics. The scripts that were collected had not reached the expectation because most of the students chose topics in biology, not in biology Education. The quality of the submitted scripts has not met expectations because it was doubted whether they could compete to win the grant from the government. Based on the result, the learning challenge in this course is to improve the interest of the students to chooce biology education topics and the quality of PKM scripts so that they could compete to win the grant.
