Qualify

of

Searveed

Quality of ilried

seaweed is physical properties

of

seaweed

in

dried condition which consisted

of

water content,

impurities,

and brightness. According

to

laboratory analysis, r,vater content

of

wet

seaweed

foi

eucherna spinosum

was

about

95%.

Then

based

on this

value, the

calculation

of

water content

with

variation

to

mass reduction

along

drying

period

can be

determined.

Table

I

presented

the

water

content

of

seaweed,

and graphically

depicted in

Figure 4 and Figure 5.

Water content

of

dried seaweed 32,43 Yo for aluminum surface and 34,21 Yo for plastic sheet

fulfilled

National Indonesian Standard (SNI-01-2690, 1998) that recommended water content

between

3l

-

35%

for euchema spinosum. Th-e success

of

drying

was determined

by

three

factors: the heat to remove water vapor,

dry

air

to

absorb the water vapor, circulation to carry

the water vapor

(Whitfield, 2000).

The surface

of

aluminum has higher evaporation rate due

to higher temperature and

wind velocity. Dryer

as high as 90 cm above the ground get higher

piastic that

laid

the

ground.

Aluminum

The level

of

calculated

by

rveighing the dried

seaweed as much as

kg,

sifted

using a manual sieve

for two

minutes. Seaw-eed that has been sifted weighed again. The level

of

impurities was calculated based on the difference

in

The average irnpurities

of

dried seaweed using aluminum about 4o/o, wl..rle using plastic sheet

5,5oA. This was caused

by

using

of

plastic that spread on the ground, so dust, sand and other

dirl

easily mixed

with

seaweed.

result was reported

by

(201i)

that the level
