Abstract

The increasing outbreak of Covid-19 is a serious epidemic that is being faced by the people of Indonesia, so it is mandatory to implement the "5M" namely washing hands, wearing masks, maintaining distance, staying away from crowds, and reducing mobility. Nowadays people prefer to use Hand Sanitizer because it is easier and more practical. The purpose of this research is to conduct counseling in the manufacture of natural hand sanitizers by utilizing natural ingredients, namely betel leaf and lime, with an effort to overcome the soaring prices and production of hand sanitizers on the market. In addition, so that people get an understanding of the manufacture of Hand Sanitizer with natural ingredients. The results obtained in this study were in the form of a natural hand sanitizer made from 70% alcohol 300 ml, 150 grams of betel leaf, and lime juice which was useful as an application to prevent the transmission of Covid-19.

Abstract

Bakteri proteolitik adalah bakteri yang dapat mendegradasi protein dengan cara memproduksi enzim protease ekstraseluler. Bakteri proteolitik dapat ditemukan pada tanah mangrove. Hal ini karena serasah daun mangrove berat keringnya mengandung dari 61% protein. Tujuan dari penelitian ini adalah untuk mengetahui adanya isolat bakteri proteolitik dari tanah mangrove di Pantai Pandaratan Kecamatan Sarudik Kabupaten Tapanuli Tengah dan mengkarakterisasinya. Penelitian ini menggunakan metode eksperimental laboratoris yang dianalisis secara deskriptif. Pengambilan sampel tanah dilakukan pada dua titik lokasi I (berpasir) dan lokasi II (berlumpur) yang diisolasi menggunakan media SMA dengan metode spread plate. Pengkarakterisasian meliputi pengamatan secara makroskopis dan mikroskopis serta uji biokimia. Hasil penelitian ditemukan adanya 15 isolat bakteri proteolitik yang diisolasi dari tanah mangrove Pantai Pandaratan Tapanuli Tengah. Uji aktivitas indeks proteolitik (IP) tertinggi diperoleh 0.82 mm oleh Micrococcus (L1) dan terendah 0.09 mm oleh Brevibacillus (L2). Sebanyak 11 genus bakteri proteolitik ditemukan antara lain, yaitu Curtobacterium (P1 dan L7), Bacillus (P2, P4, dan P7), Enterococcus (P3), Brevibacillus (P5 dan L2), Carnobacterium (P6), Paenibacillus (P8), Micrococcus (L1), Vagococcus (L3), Marinococcus (L4), Halobacillus (L5), Sporosarcina (L6).
