Abstract

The research was conducted in Sumatra Mushroom Garden, Mushroom Cultivation, on Jln. Benteng Hilir, No. 19. Bandar Khalifah Kec. Percut Sei Tuan Kab. Deli Serdang village with a height of 12 m above sea level. The design used in this study is a Non Factorial Complete Randomized Design (RAL). Media composition research factor grows with 6 treatment levels namely: B0: 100% sawdust, B1: 100% sugar cane amp, B2: 100% sago amp, B3: 50% cane amp ; 50% sawdust, B4: 50% sago sago amp 50% sawdust, and B5: 50% sugar cane amp + 50% sago amp. Observation parameters are: percentage of baglog ysng covered in mycelium, the growth of mycelium closes the substrate/ baglog, the age of the appearance of the fruit body, the number of bodies of the fruit, the diameter of the fruit hood, the length of the stalk of the fruit body, and the wet weight of the harvest. The results showed that: 1) The composition of the growing media had a very noticeable effect on every parameter except the baglog percentage parameter covered in mycelium. 2) Media growing 100% sugar cane cane juice produces the longest mycelium (21.94 cm), the emergence of the fastest fruit body (64.50 hsi), the diameter of the widest fruit hood (18.17 cm), the highest number of fruit bodies (14.5 pieces), the longest fruit stalk (4.53 cm), and the highest harvest wet weight (137.00 g/baglog).
