Abstract

Penelitian Uji Aktivitas Antifungi Ekstrak Etanol Gal Manjakani (Quercus infectoria)  terhadap Candida albicans telah dilaksanakan pada 5 Desember 2015 hingga 27 Mei 2016 di Laboratorium Pendidikan Biologi serta Laboratorium Pendidikan Kimia Fakultas Keguruan dan Ilmu Pendidikan Universitas Syiah Kuala. Penelitian ini bertujuan untuk mengetahui adanya aktifitas antijamur serta pengaruh berbagai konsentrasi ekstrak etanol gal manjakani dalam menghambat petumbuhan C. albicans. Jenis penelitian ini adalah eksperimental laboratorium dengan menggunakan Rancangan Acak Lengkap (RAL) yang dibagi dalam 6 kelompok perlakuan, yaitu 4 kelompok ekstrak gal manjakani (konsentrasi 20.000, 40.000, 60.000, dan 80.000 ppm) dan 2 kelompok kontrol menggunakan NaCl 0,9% dan Nystatin. Pengujian yang dilakukan meliputi uji fitokimia serta uji daya hambat menggunakan metode difusi lubang sumuran. Analisis data menggunakan Anova (analysis of variance) kemudian dilanjutkan dengan uji Beda Nyata Jujur (BNJ) pada taraf uji 5%. Hasil uji fitokimia ekstrak etanol gal manjakani ditemukan adanya kandungan senyawa alkaloid, flavonoid, tanin, saponin, polifenol, triterpenoid. Hasil analisis data menunjukkan bahwa ekstrak etanol gal manjakani memiliki pengaruh yang nyata dalam menghambat pertumbuhan C. albicans. Sedangkan berdasarkan uji lanjut BNJ tidak terdapat perbedaan yang signifikan antara ekstrak etanol gal manjakani konsentrasi 80.000 ppm dengan Nystatin sebagai kontrol positif dalam menghambat pertumbuhan jamur C. albicans

Abstract

One of the places most visited by people every day is a traditional market. Various activities such as buying and selling various household purposes can be found the place. The activity becomes one cause of waste that must be overcome market. The waste produced can be either solid waste and wastewater management. Liquid wastes big opportunities for development of various microorganisms that are harmful to humans, such as the bacterium Escherichia coli and the like. Traditional markets liquid waste generated every day cause various health problems such as diarrhea and the others. The disorder is caused by bacterial pathogens present in the liquid waste. Research Density Bacteria are the Liquid Waste Traditional Market has been held on since February-March 2016. This study aims to determine the density of the bacteria present in the wastewater traditional markets in the city of Banda Aceh. The sample in this study is the liquid waste sanitation traditional markets, namely the Rukoh Market, Peunayong Market, Neusu Market, Keutapang Market, and Seutui Market. The method used in this research is descriptive. Data collection was carried out in three stages, namely liquid waste sampling, measurement of the value of Optical Density (OD), and Total Plate Count (TPC). The results obtained by bacterial density is highest in the wastewater by the number of colonies as much as 20 x 1010  CFU / ml at 10-9 dilution level that has a value Optical Density (OD) is the highest in the market Seutui 0512 nm, while the fewest number of bacterial colonies found in wastewater with the number of colonies of bacteria 3 x 107 CFU / ml at the rate of dilution of 10-6 which has the lowest value of optical density is 0.051 nm at Rukoh Market.
