Abstract. Majority of Mertasinga citizens work as fishermen who most often catch crabs.
Then the crabs are marketed in the traditional market and the meat is collected to be sent
to factories. The factories then make variety of processes food from the crab meat.
However, the process of collecting meat leaves a heap of crab shells that becomes fishy-
smelling waste and pollutes environment because biological oxygen demand (BOD) and
chemical oxygen demand (COD) increase. To solve the environmental problem caused by
the crab waste, a waste management is needed. The objective of this study is to examine
the literature study of various research results concerning the processing of small crab
shell waste into something that has economic value. The result of the study found out that
the crab shell waste contains (a) protein (b) crude fiber, (c) calcium, and (d) phosphorus.
As the waste is rich in content, several studies have processed the waste into: (a) breeding
animal feed, (b) making crackers, (c) making natural food flavors, and (d) chitosan.
Branding and copyright of the product are obtained to make the product more valuable. In
addition, high quality product is maintained according to the quality assurance standard
with affordable price so that it can increase the living standards of the citizens.
Keywords: Environmental pollution, Crab Shell Waste Management, Economic value of

1 Introduction
Mertasinga village is a coastal area which has crabs as its major potency. The crab is a
group of crabs from the family of Portunidae which is known as a blue swimmer crab and it is
classified as a species of Scylla serrate [1]. As the crab potential is evident, the citizens of
Mertasinga village take the advantage of it as a source of their income by being fishermen or
laborers who skin the crab and take the meat to be sent to factories. From the skinning process
in figure 1.1, it can be seen that the process leaves meat and a heap of crab shells in figure 1.2
and 1.3. The effect of the activity is environmental pollution which is indicated by the
increasing amount of biological oxygen demand (BOD) and chemical oxygen demand (COD)
that is higher than the standard allowed as happened in the Turag river Dhaka, Bangladesh [2].
BOD and COD is a measure of rainfall, temperature, and waste composition [3].
