Studi Pertumbuhan dan Produksi Jamur Tiram Putih (Pleurotus ostreatus) pada Formulasi Media Tumbuh Serbuk Ampas Tebu dan Ampas Teh

Abstract

A Study on the Growth and Production of Oyster Mushroom (Pleurotus ostreatus) on the Formulation of Sugar Cane Powder and Tea Dregs as the Growing Media. Thesis. Supervised by Siti Mardiana as the head of supervisors and Ellen L. Panggabean as the second supervisor. The aim of this study is to find out the increase in growth and production of white oyster mushroom (Pleurotus ostreatus) by using sugar cane powder and tea dregs as the growing media, conducted at Sumatera Kebun Jamur, Jalan Benteng Hilir No. 19 Bandar Khalifah, Percut Sei Tuan, which is 12 m above sea level with a flat topography and alluvial soil type. This study was started in April 2017 and ended in July the same year. The design used in this study is the Non-factorial Complete Random Design with the treatment of growing media formulation factor, which consists of 5 levels of treatment, namely: A0 = 100% sawdust; A1 = 100% sugar cane powder; A2 = 100% tea dregs; A3 = 75% sugar cane powder + 25% tea dregs; A4= 50% sugar cane powder+ 50% tea dregs; and A5 = 25% sugar cane powder + 75% tea dregs. This study was repeated 4 times. The parameter observed is the growth of the mausoleum covering the substrate/backlog (day), the percentage of backlogs covered by mausoleum (%), age for appearance of pin head (HIS), pin head diameter (cm), fruitingbody length (cm), number of pin heads, wet weight on cultivation/backlog (g). Findings from this study shows that treatments A1and A3are the best media in enhancing the growth of oyster mushroom, on which the pin heads appear faster, fruiting body is of a larger size and longer, with a larger diameter, greater number of pin heads, and greater wet weight on cultivation. The formulation of growing media significantly influences the growth of the mausoleum covering the substrate/backlog (day), the percentage of backlogs covered by mausoleum (%), age for appearance of pin head (HIS), pin head diameter (cm), fruiting body length (cm), number of pin heads, wet weight on cultivation/backlog (g).
