Abstract: Sidat fish (Anguilla marmorata)) is one of consumed fish species with relatively high nutrition contents,
vitamins, micronutrients and albumin. Similarly, albumin is found in toman fish (Channa micropeltes) which
is of the same family as gabus fish (Channa striata). In this research, sidat fish (Anguilla marmorata) is
obtained from fish farms in Lamongan while toman fish (Channa micropeltes) is naturally obtained from
Banjarmasin, South Kalimantan where the two fishes have high albumin content. The investigation is aimed
at analysing the albumin level in sidat fish (Anguilla marmorata) found from fish farms and toman fish
(Channa micropeltes) found naturally in swamps. The samples used for sidat fish and toman fish had
average weight of 250 and 230-250grams respectively. Using unpaired T-test from SPSS 23, the data
analyses showed the average albumin level in sidat fish and toman fish is 𝑋
̅
= 13,2025 and 𝑋
̅
= 10,807
respectively. This means that there is a significantly high difference in the albumin level found between sidat
fish (Anguilla marmorata) and toman fish (Channa micropeltes).
1 INTRODUCTION
Fish is one of the most abundant food sources
beneficial for its protein content and medicinal
purposes. Protein has specific function in terms of
building and maintaining cellular tissues inside our
body which cannot be replaced by other nutrients
(Almatsier, 2004). As energy source, protein is
needed at appropriate amount so that balanced
nutrient intake can be achieved as well (Astawan,
2007).
In the first place, naturally-occurring protein,
also known as native protein, can undergo changes
due to heating process (denaturation). This happens
as a result of the degradation of chemical bonds in
its tertiary structure and secondary molecules, which
in turn allows protein to be more easily digested by
hydrolytic enzymes during metabolism process
inside the digestive system (Lean & Michasel,
2013).
There are a number of globular proteins
present inside our body, such as albumin, globulin,
histone, and protamine (Anna, 2007). Albumin is a
water-soluble protein and coagulates by heat. It is
the most abundant protein inside blood plasma at
about 60% of the total plasma volume at 4.5 g/dL.
Albumin functions to maintain plasma osmotic
pressure and to transport small molecules through
plasma as well as other extracellular fluids
(Montgomery, 1993).
Other than that, albumin regulates
intravascular colloid osmotic movement, eases the
movement of internal body fluid and facilitates
transport of nutrients inside the body. In a typical
human body, alongside other proteins, albumin is
synthesised by liver tissue at ± 100-200 µg/g per day
(Suprayitno, 2003). Inside human body, albumin has
important role during post-op wound healing due to
its antinociceptive and anti-inflammatory
characteristics (Suprayitno, 2003; Mat Jais, 2008;
Mat Jais, 1997).
One way to boost albumin intake is by
consuming HSA (Human Serum Albumin).
However, it is very expensive thus alternatively
people look for white egg, sidat fish or toman fish
which are cheaper yet contain albumin with similar
clinical aspects. Also, albumin from fish extract is
also proven to contain omega-3 and omega-6 fatty
acids (Mustafa et al., 2012).
In previous studies, Indonesians have used
fish for its albumin content. For instance, people in
Banjarmasin, South Kalimantan, make use of
steamed gabus/toman fish for wound healing from
afterbirth processes (Mustafa et al., 2012). From this
study, it was proven that albumin extracted from
