Abstract

Kabau (Archidendron bubalinum) merupakan tumbuhan yang termasuk famili Leguminosae berbentuk pohon dan menghasilkan biji berwarna hijau. Masyarakat Bengkulu memanfaatkan buah kabau sebagai lalapan. Bagian kulit buah tumbuhan kabau berpotensi sebagai antifungi Candida albicans karena mengandung senyawa fitokimia. C. albicans merupakan salah satu mikroorganisme patogen penyebab infeksi seperti kandidiasis, sariawan, lesi pada kulit, dan vulvovaginitis. Penelitian ini bertujuan untuk mengetahui potensi ekstrak kulit buah kabau sebagai antifungi serta mengetahui konsentrasi ekstrak yang optimal dalam menghambat pertumbuhan fungi. Ekstrak kulit buah kabau diuji pada fungi C. albicans dengan metode difusi menggunakan kertas cakram pada media Sabouraud Dextrose Agar (SDA). Ekstrak kulit buah kabau dilarutkan dengan pelarut aquades dan dimetil sulfoksida 2% pada konsentrasi ekstrak 5%, 10%, 20%, 40% dan 80%. Hasil penelitian menunjukkan konsentrasi 40% dengan pelarut aquades yang paling efektif dalam menghambat pertumbuhan fungi C. albicans dengan diameter daya hambat 4,05 mm. Dari data hasil penelitian tersebut, maka dapat disimpulkan bahwa ekstrak kulit buah kabau berpotensi sebagai antifungi C. albicans.

Abstract

The presence of dye liquid waste from industry that is discharged into public drainage channels will cause environmental pollution, especially water ecosystems. The impact caused when exposed to waste such as health problems, such as allergies, skin irritation, cancer, and mutations in humans. The most widely used waste treatment method is adsorption. This method was chosen because it has high efficiency, easy, and cheap. The success of the adsorption method depends on the type of adsorbent used. One of the adsorbents that has a large adsorption capacity is metal organic frameworks. This study aims to determine the adsorption capacity using a sulvothermally synthesized Metal Organic Frameworks adsorbent using FeCl3.6H2O metal with terephthalic acid organic ligand. The dyes used as adsorbates are cationic malachite green (MG) and violet dye (VD) which are hazardous wastes from the textile industry in Bengkulu city. Determination of adsorption capacity is done by first determining the optimum conditions which include pH, contact time, adsorbent weight, and temperature. The optimum conditions for MG dye were at pH 5, at a mass of 2.5 mg, a contact time of 60 minutes, at a temperature of 30°C and a concentration of 50 ppm. While the VD dye was at a mass of 10 mg, a contact time of 40 minutes, pH 4, temperature 30°C and a concentration of 50 ppm. The adsorption capacity of MG and VD dyes were 625.00 mg/g and 384.61 mg/g.
