Abstract

The quality of mother culture is one of Oyster Mushroom cultivation’s essential factors as it determines the quality and quantity of the crop. Potato Dextrose Agar (PDA) is the most common media for making the mother cultures of edible mushrooms; therefore, it is essential to find alternative media to increase crop yields. This research aims to find out the most effective alternative media of mother of pink oyster mushroom (Pleurotus flabellatus) and the effect on the phytochemical characteristic. The research method used was experimental research, a completely randomized single factor experiment, with four treatments and six repetitions: PDA ( Potato Dextrose Agar), CDA (Cron dextrose Agar), GBDA (Green bean dextrose Agar ), SDA (Soy dextrose Agar). The Agar medium was used to measure pink oyster growth, while broth media were used to determine the biomass weight and the phytochemical compound. The research results showed that the diameter on the CDA medium had the most extensive results among all. Biomass test results showed that the most effective media to obtain biomass were the CDB and GBDB medium. The Phytochemical obtained were alkaloids and saponins, while steroids and tannins were not detected in all samples.
