Currently Malaysia is the third
largest sago producer in the world after Indonesia and Papua New Guinea which
combined produce approximately 94.6 % of the world production (Istalaksana et al., 2005). By 2012, all four
districts in Mukah division, namely, Mukah, Dalat, Matu, and Daro, have
cultivated an estimated 11,112 hectares, 28,169 hectares, 4,306 hectares, and
3,149 hectares of sago, respectively by comparing the data with data produced
by the Department of Agriculture Sarawak. Sago is deemed as a next viable
commodity crop in Sarawak given the fact that about 1.69 million hectares of
peat soil can be cultivated with this palm (Chew et al., 1998).
Sago palm is among the largest
plant in Sarawak to produce sago flour. In addition, the sago tree bark is used
to make platform around the factory and as footpaths of houses and shredded
barks fraction used for the consumption of electricity. Most of the shredded
bark will be thrown into the river. Sago palms generate a huge amount of waste products
such as chopped trunks, dead fronds, shells and fibers.
Due to the lack of adequate systems of accumulation and
treatment, this waste is released into waterways or incinerated. This
overabundance of sago waste is actually contribute to the environmental
problems result in a nutrient imbalances, toxic elements and phytotoxicity in
corps (Awg-Adeni et al., 2010). The effluent of sago waste causes a pollution which
leads to a serious effect to the environment results inefficient solid waste
management. The excess amount of liquid and suspended solid residues throw off
the river composed large amount of lignin and cellulose. According to Quek et al. (1998), lignin and cellulose from
sago waste has a high potential of bio absorbent component to cause a polluted
environment. With a high humidity starch content, sago waste is difficult to be
handling (Awg-Adeni et al., 2010).
A good alternative for utilizing agriculture waste like sago
waste is by converting it to compost. Compost is a control decomposition of
organic material that can be dug into soil as well to improve soil structure or
nutrient quantity in order to be used as useful products (Irshad et al., 2013). Compost is the best way
for waste disposal which enables recycling organic matter despite of its role
as an environmental friendly. According to Lima et al., (2004), previous research has been proved that compost can
help in reducing space as well as giving the nutrient needed for the plant. The best treatment for SB waste
is by composting and will reduce the overloading of the municipal tips and make
available, organic soil amendment which can be used in the city’s gardens and
seedbeds, thus reducing municipal expenditure on imported peat.
research aimed to investigate the physicochemical characteristics, maturity and
stability of SB compost prepared in a three-month period. The seed germination
and plant growth studies were also conducted to assess the applicability of the
prepared composts as plant growth medium.
