Abstract: The quality of seaweed is influenced by the type of seaweed seed,
harvesting age,
, and the crucial process that is the drying process. The local practice of
drying of the seaweed
is by spreading it over a plastic sheet on the ground and exposing
it to the suri unfortunately,
such traditional practice of drying seaweed has led to increased
risk of contamination of
seaweed by dust and sand parlicles and other impurities, as well
as seaweed often suffer from
lower quality. This research was conducted to examine the effect
of application of cabinet
type dryer on quality of dried seaweed, through indicators
of watii content, level of
impurities, and brightness. The dryer was designe-d by using aluminum
as a drying surface,
with holes for circulation, and blackened surface to in"..ase temperature.
The r:esults. of
study shows that the usage of cabinet type dryer decrease
water content rapidly, reduce level
of impurities, and improve brightness oidried seaweed.

Result and Discussion

3.1 Characteristic of Drl,er

Characteristic of cabinet type dryer is presented by ternperature and wind velocity o1 the
drying surface- The daily tempemtures and wind velocity were measured from g.00 to 16"00
for 3 days. Surface tempemture was measured by toucling the end of thermometer on the
surface of the dryer without load condition. The analysis of average daily temperature
was
shown in Figure 2.

Wheireas aluminum surface resided 90 cm above the ground surface so did not block
bushes, trees and other objects. Wind velocity on aluminum surface was higher than at

3.2 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
winlthan piastic that laid on the ground. Aluminum surface has 400 holes/m2 that allow
circulation occured either from below and above surface.

The level of impurities calculated by rveighing the dried seaweed as much as 2 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 rveight before ar-rd weight after sifted.
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. Similar result was reported by Surata (201i) that the level of
inrpurities about 5,25o/o when using plastic for drying seaweed,

Based on discussion and analysis that obtained from this
study, it can be concluded that
cabinet type dryer worked better than usi,g plastic sheet.
Thl quality of dried seaweed
improved that can be seen from the decrease in water content
and level of impurities, and
increased the brightness of dried seaweed.
