Daya reduksi merupakan salah satu indikator potensi aktivitas suatu senyawa sebagai antioksidan. Penelitian ini bertujuan untuk menentukan daya reduksi ekstrak etanol biji Aquilaria microcarpa, Aquilaria malaccensis, dan Aquilaria beccariana terhadap Ion Ferri (Fe3+). Serbuk kering biji A. microcarpa, A. malaccensis, dan A. beccariana dimaserasi menggunakan etanol 70%.   Daya reduksi ditentukan dengan metode FRAP (ferric reducing antioxidant power) yang didasarkan atas kemampuan senyawa dalam mereduksi senyawa besi(III)-tripiridil-triazin menjadi besi(II)-tripiridil triazin pada pH 3,6. Absorbansi diukur menggunakan spektrofotometer UV-Vis pada panjang  gelombang  598  nm.  Hasil  penelitian  menunjukkan  ekstrak  etanol  biji  A.microcarpa, A. malaccensis, dan A. beccariana mempunyai daya reduksi berturut-turut sebesar 6,39±1,58; 119,95±28,04; dan 62,12±6,57 µM ekivalen troloks/g ekstrak.

 Abstract (English)

The availability of natural agarwood tends to decrease and encourage some parties to cultivate agarwood producing plants by using biological inoculation method that is microbe. In relation to this, many manufacturers produce inoculant products used to inoculate agarwood  trees. This research is aimed to get some agarwood inoculant products in South Kalimantan. The inoculant products used in this study were obtained based on information from agarwood farmers in South Kalimantan. Based on observation result, inokulan products have varied form ie liquid, capsule, and stick. In addition, these products do not fullfil the packaging standards such as the absence of date of manufacture, trade license, and expiry date. The result of identification of dominant microbes inokulan product design showed some products formed from microbial species that function in agarwood formation that have not been studied even at risk of endangering human health. The results of this study are expected to be an input for farmers to be more careful in choosing the right inoculantproducts and become a driver for producers to improve the quality of inoculants produced.sls
