| Summary: | Agricultural wastes which are defined as unwanted waste that is produced from
agricultural activities can be converted to a useful resource which is by mushroom
cultivation. Paddy straw (PS) and saw dust (SD) is one of the agricultural wastes that are
abundant and readily available where both of the agricultural wastes are combined with
sago waste (SW) binder at a fixed ratio to determine the optimum ratio of agricultural
wastes/sago waste biofertilizer. This study focuses on recycling the agricultural wastes in
order to reduce the environmental pollution caused by improper disposal of biomass. The
methods used in this project includes, sterilizing, drying, grinding, and mixing of
substrates for the preparation of mushroom plantation. This study focuses on the
performance of agricultural wastes/sago waste biofertilizer on two different types of
mushroom species which are grey oyster mushroom and white oyster mushroom. There
are many factors that affect the mushroom cultivation process such as moisture content,
and pH value where this study also analyses these properties to determine the best ratio
of agricultural wastes/sago waste biofertilizer. The study also conducts characterization
of the spent mushroom substrate (SMS) and fresh mushroom substrate (FMS) which
consists of TGA analysis, SEM-EDS analysis, and FTIR-ATR analysis. After the analysis
is done, it is determined that the optimum ratio for agricultural wastes/sago waste
biofertilizer is 70% paddy straw and 30% sago waste followed by 50% paddy straw and
50% sago waste. The results also show that the sago waste is able to perform well as a
binder at an optimum composition as excess sago waste will disrupt the mycelium growth
of the substrates. Lastly, based on the results that have been analysed, it is determined
that the agricultural wastes/sago waste biofertilizer performs better on grey oyster
mushroom compared to white oyster mushroom. |
