Maggot – Bioconversion Research Program in Indonesia
Concept of New Food Resources
Results and Applications


Saurin Hem (IRD France)

The bioconversion of Palm Kernel Meal (PKM) is a natural process consisting of extracting
nutrients residue in this by-product, into a form of insect larvae biomass. This is a new source of
animal proteins and fats for aquaculture. The insect in the bioconversion process (Hermetia
illucens, F. Stratiomyidae, O. Diptera) or Black Soldier Fly (BSF) is well known in USA as amongst
the best biodegradation agents.

The first research program in 2005 to 2007 consisted of investigating the biology and life-cycle of
Hermetia in the Indonesian climatic conditions. Many data have existed especially from USA,
where BSF has considered as benefited insect which may provide many good services for
humanity and environment. However, previous research before any vulgarization to the population
we need a strong evidence about the non aggressively from the insect. The life cycle may be
different from one place to another. A complete observation has been made on the larvae stage. The
number of instars and molting during the pre-pupa stage, have been precisely established. This is a
tentative method for aging the larvae stage, which may use as reference mark during the
development of the larvae. Larvae aging is a bio-data need to put in relation to the larvae biodegradation activity.

This is an example of some news research need that we have done mainly
accomplished. Many researches have been investigated on the adult stage like differentiation male
from female or some bio parameters like relative fecundity with female body length or the
correlation between eggs mass and it related numbers. All this activities have taked us for two
years and the opportunity to provide the research topic for a S2 graduation at the IPB University in
Bogor. Two others graduations have been accomplished on microbiology (fungus and bacteria)
during the fermentation processing of PKM previously prepared before the larvae take actions.
During this research period, we have discovered a biofertilizer come from the metabolism rejects
from the larvae. This topic has been proposed to the laboratory of plants physiology of UI
(University of Indonesia), another opportunity for a S2 graduation. All this research have put us to
involve for two year. After trials in the laboratory in BRBIH Depok, the application actions have
been transfer to in the BBAT Sungai Gelam- Jambi, a pre-field application. The goal was to
evaluate if any harmful impacts on the environment or on the human being.

The tryout for an intensive culture at BBAT Sungai Gelam has been started. During the whole year
of 2007, the fieldtest has been proof that high density BSF rearing is possible. The processes have no negative
impact on the environment nor on human habitat. The BBAT became a “show room” to promote
maggot for the farmers from the Jambi province and from the bordering provinces like Bengkulu,
Riau. The results have concluded that Hermetia population can be domesticated to biodegrade
PKM into Maggot biomass for aquaculture. On 2009, a pilot project has been decided in common
agreement between IRD/BRKP/DGA, together to setting up at Singkut village as a real scale tryout
“a Maggot pilot project” to learn and to reorient if any rectification to optimize.

This is a very detailed study rich in information about the BSF life cycle and use in bioconversion or waste on a fairly large scale. The study is over 100 pages long but is well worth looking over.

Digester (concrete tank-image left), with 3m in diameter and 0.6 m high wall which contains about 36 million by larvae capable of biodegrading 50kg of fish waste in 4 to 6 hours.


*I'm not an entomologist, and much of what I write about BSF is an educated guess.

Link is broken. Anybody here have the PDF version? Google search is only coming up with other papers that are quoting this study.

I think I already have introduced myself (long time ago) will check.

I thod the link was for free, but later I found it requires a subscription to scrib. You can get it using the free trial, but you have to remember to remove your membership or they´ll start charging your creditcard monthly.
