IMPROVED COST EFFICIENCY IN PRODUCTIVITY WHITE OYSTER MUSHROO THROUGH THE USE OF THE MEDIA GROWS STERILIZATION BOX

Abstract

Sterilization is one of the decisive stage in the process of the cultivation of mushrooms. Sterilization of microbes such as bacteria suppressing aims, the yeasts and mould inhibit mold growth. Growing media sterilization technology used by small industries white Oyster Mushrooms are still simple to use
drums/steamer with a capacity of 40 logs, so that for the amount of log that much needs to be done many times so it is not efficient time and expense. Outreach activitie s carried out on small industries in jl Murjani the city of Palangkaraya, for 8 months in 2009. The purpose of the activity is to do a trial sterilization box in increasing the efficiency of aquaculture production cost white Oyster mushrooms. Sterilizatio n box made of wood boards which are coated with aluminium length 1.50 m, width 1.25 m and height 1.25 m, capable of accommodating 325 baglog size of 1.2 kg. capable of accommodating 325 baglog size of 1.2 kg. The perforated sterilization box below it is mo unted on top of the drums containing water that is heated with a stove senawar. Trial results show that sterilization has been performed on the sterilization at a temperature of 85-90 degrees Celsius for 14 hours spent fuel kerosene 10 liters. Sterilizatio n sterilization by using the box is capable of lowering the level of contamination of area of 7.69% with cost efficiency 69,23%.
