ANALISIS KELAYAKAN LAHAN BUDI DAYA RUMPUT LAUT (ULVA SP.) PADA LOKASI RENCANA PENGEMBANGAN NORTH SULAWESI MARINE EDUCATION CENTER DI LIKUPANG TIMUR
ABSTRACT: The purpose of this
research was to know and evaluate the condition of aquatic environment and
water quality parameters for cultivation of seaweed Ulva sp. This research was
conducted on North Sulawesi Marine Education Center (NSMEC). NSMEC is planned
to be built at Marine Field Station FPIK UNSRAT located in Likupang Timur
Kabupaten Minahasa Utara. The waters of NSMEC development area are
geographically located at 1040.437 'LU and 12504.499' BT. The determination of
4 stations was done by purposive sampling which was considered to represent the
condition of waters. Coordinate stations were recorded with GPS help. The data
were collected for 14 days every 6:00 pm, at 12:00 pm and 17:00 pm. The
observation of environmental conditions was carried out for protection factor
and substrate of water base, while water quality parameter measured in situ
included depth, brightness, temperature, dissolved oxygen (DO) salinity, pH and
current velocity. Phosphate, nitrate and total suspended solid (TSS) were
measured. Tide measurements were measured every hour for 24 hours. Data
analysis used conformity matrices that included scores and weights for the
determination of conformity classes. Class suitability was used to describe the
suitability of seaweed. The results showed that the waters of the NSMEC
development zone were in class S1 meaning very suitable for seaweed cultivation
location. The analysis results of each station found that 4 stations were very
suitable. As conclusion, water environment and water quality parameters of the
waters of North Sulawesi Marine Education Center development area located at
Marine Field Station FPIK UNSRAT were categorized as very suitable for seaweed
cultivation, Ulva sp.
