Abstract

Indonesia memiliki keanekaragaman tumbuhan yang sangat tinggi. Banyak di antara tumbuhan tersebut memiliki khasiat sebagai obat, misalnya belimbing manis (Averrhoa carambola L.). Secara tradisional, belimbing manis telah digunakan untuk mengobati berbagai macam penyakit. Kemampuan ini diduga karena belimbing mengandung senyawa yang berpotensi untuk menghambat pertumbuhan bakteri. Penelitian ini bertujuan untuk mengetahui pengaruh ekstrak metanol daun dan kulit batang belimbing terhadap pertumbuhan Methicillin Resistant Staphylococcus aureus (MRSA). Ekstraksi tumbuhan dilakukan dengan metode maserasi sementara aktivitas anti bakteri dilakukan dengan metode Kirby-Bauer. Pada uji aktivitas antibakteri menggunakan tiga (3) konsentrasi ekstrak yang berbeda, yaitu: 25, 50, dan 70%. Sebagai negatif control digunakan metanol dan sebagai positif control digunakan linezoid. Hasil pengamatan menunjukkan bahwa ekstraksi batang pada konsentrasi 75% memiliki kemampuan daya hambat yang terbesar terhadap pertumbuhan MRSA

Abstract

Kitosan memiliki sifat antibakteri sehingga dapat dimanfaatkan sebagai bahan pengawet ikan. Penelitian ini dilakukan di Laboratorium Mikrobiologi Universitas Syiah Kuala, Banda Aceh dari bulan Mei sampai Agustus 2012, untuk mengisolasi dan mengkarakterisasi  bakteri pada ikan kembung (Rastrelliger sp.) asin berkitosan. Metode yang digunakan dalam penelitian ini deskriptif. Dari hasil isolasi didapat enam isolat yang memiliki morfologi koloni dan sel yang berbeda. Isolat yang memiliki bentuk bundar (50%), elevasi cembung (33,3%), tepian licin (50%) warna kuning (66,7%), sel bakteri gram positif (66,7%), bentuk sel bulat (100%), tidak berspora (66,7%) dan bersifat motil (66,7%).

Abstract

Abstract. Dental caries is a disease with a high prevalence of caries in Indonesia is caused by the bacterium Streptococcus mutans. The leaves of the soursop (Annona muricata Linn.) is one of the herbs that can remove dental plaque. This study aims to determine the chemical content and measure the inhibitory antibacterial soursop leaft methanol extractin inhibiting the growth of Streptococcus mutans bacteria. Phytochemical screening stated that the leaf of the soursop contains flavonoids, alkaloids, tannins, steroids, glycosides and saponins. Test of inhibition were measured using paper disc diffusion method with variation concentrations of 5, 10, 15 20, and 25%, positive control is tetrasilkin 30 µg, and a negative control is methanol. Antibacterial test results showed that the methanol extract of soursop leaves have antibacterial activity against Streptococcus mutans at concentrations of 5, 10, 15, 20 and 25% with inhibitory diameter of 9,1; 10,57; 11,53; 12,01 and 13,75 mm respectively. Keywords: Soursop leaves, Dental caries, Streptococcus mutans, Methanol.*Judul ini telah dipresentasikan pada Seminar Nasional: Indonesian Students Conference on Science and Mathematics (ISCSM) 11-12 November 2015, Banda Aceh Indonesia

Abstract

N-hexane extracts of the bark from black plum(Syzygium cumini (L.) Skeels) showed activity againtSalmonella typhi. Meanwhile,  the result showed that N-hexane was not able to inhibit the  growth of Candida sp. The research was done at Microbiology laboratory, Biology Department Faculty of Mathemathics andScience,  Syiah Kuala University. The bark of black plum were collected from Aceh Besar District. The extraction method  for black plum used maceration with N-hexane and than concentrated in rotary evaporator. The disc diffusion method used to screen the antimicrobial activity with 20 %, 30 %, 40 % dan 50 % concentration.

Abstract

Bananas are a cultivated crop that has been cultivated for a long time in Southeast Asia. They are readily available in Indonesia, particularly in the province of Aceh. Utilization of banana stem parts is still less than that of the leaves and fruit. One potential business opportunity is to utilize banana stem waste to create innovative crafts, such as pencil cases, tissue boxes, decorative flowers, wallets, and other similar items. The methods used include training and a respondent survey. The training was conducted with teenagers and homemakers from the Family Welfare Movement (PKK) group in Peukan Bada District. A study was conducted to assess the feasibility of craft products among 30 respondents from various segments. Creative crafts utilizing banana stem waste offer potential opportunities for development in Aceh Province, given the abundance of banana trees.
