| Summary: | Effective Microorganism (EM), discovered by Professor Dr. Teruo Higa, consists of
effective, beneficial and non-pathogenic microorganisms was found as the credible
approach to solve many environmental problems regarding the polluted rivers, drains, ponds, lakes and so many more. Until today, the halal issues caused by the ingredients of EM still are not clearly mentioned by the manufacturer and becomes a concerns to most of the Islamic country like Malaysia. As the solution, halal based source are suggested in utilization of Effective Microorganism (EM). The laboratory test procedure for wastewater treatment was done by using own design of wastewater treatment tank by referring to common wastewater design pond in industrial which are able to run the samples up to 30 liters. For this experiment, three suitable wastewater samples from Indah Water (residential waste), Tasek Melati (Lake water) and palm oil mill effluent
(industrial waste) were used. The result of the experiment shows that EM mudball has
the potential to solve the problem regarding treating the wastewater as it positively
reducing the level of turbidity, biological oxygen demand, chemical oxygen demand, as
long as also being able to work with pH and dissolved oxygen of applied sample in
getting the level which suitable for aquatic life. For lake water, the percentage reduction
of biological oxygen demand, chemical oxygen demand and turbidity is 75.91%,
77.87% and 67.29%. For residential waste, the percentage reduction of biological
oxygen demand, chemical oxygen demand and turbidity is 74.3%, 78.67% and 52.74%
while for the palm oil mill effluent, percentage reduction of biological oxygen demand,
chemical oxygen demand and turbidity is 2.78%, 0.48% and 0.39%. The results
obtained shows that EM mudball are not very efficient in treating palm oil mill effluent
but it is quite effective in treating lake water and residential waste. In this work, a little
modification of original EM mudball was made by the addition of Malaysia’s herbs
extracts as the finding that this plants contains derivative compounds, stated as
phytochemicals which have a potential to killed mosquito’s larvae by acts as poisoning
food to them. This new modified EM mudball can kill the mosquito’s breed in serving
the safe environment for human and it is was guaranteed to be safe for all others
aquatic’s life. The experiment was done by tested the ability of three different type of
EM mudball in killing the mosquito larval. Then, the further experiment was runs to test
whether the quantity of Malaysia’s herbs extracts will influences the efficiency of
killing the mosquito larvae. The obtained results has shows for 80% (8 out of 10
mosquito’s larvae) of died mosquito’s larvae for 25% of herbs extract added compared
to 40% (4 out of 10 mosquito’s larvae) of died mosquito’s larvae for 15 % of herbs
extract added and 30% (3 out of 10 mosquito’s larvae) of died mosquito’s larva for 5%
of herbs extract added. |
