GAMBARAN SEBARAN KONDISI TERUMBU KARANG DI PERAIRAN KECAMATAN SANGKULIRANG DAN SANDARAN KABUPATEN KUTAI TIMUR
ABSTRACT: Sangkulirang and
Sandaran as the most northern coastal districts of East Kutai Regency with status
of under developing area and yet optimize in accessibility, thus also yet
optimal in environment management and observation in this term the coral reef
ecosystem. In order to providing the
coral reef status information in Sangkulirang and Sandaran District, and
further the result could be consider as database in evaluation of future change
in coral reef status due to the coastal area development, then this study were
conducted in those two districts with field data collecting was held at October
12th - 17th, 2012. The coral percent
cover data collecting and analysis were using method of lifeform line intercept
transect according to English, et al (1994) and Keputusan Kepala Badan
Pengendalian Dampak Lingkungan No.47 year 2001, while the reef condition
category were determined from the life hard coral (HCL) percent cover by based
on Keputusan Menteri Negara Lingkungan Hidup No.4 year 2001 that divided into
four category: 1) poor/bad (HCL < 25 %), 2) fair/moderate (HCL 25% - <
50%), 3) good (HCL 50% - <75%), and excellent (HCL ≥ 75%). The data of reef distribution and area wide
were obtained by direct GPS plotting in the field survey with satellite image
assist, and further processed using GIS program. According to the result, the
coral reef in Sangkulirang and Sandaran District both in same condition that
categorize into fair/moderate condition with each coverage of HCL 48.1% and 41.4%,
and the combine in average HCL 45,9% also in the same category. Overall of both districts estimated had
2,221.57 ha of coral reef area with condition vary from poor/bad till good category. 761.27 ha of coral reef was estimated in
Sangkulirang District and 1,460.30 ha in Sandaran District. The coral reef area in both districts
commonly forming a narrow stretch of reef develop along the edge of drop-off
bathy profile. Factors of limitation and degradation toward the coral reef
development in both districts are: i) non-anthropogenic (nature) factor,
majority the turbidity and sediment load from river estuaries and sea current
and wave, and ii) anthropogenic (human) factor in activities of destructive
fishing method especially by explosive fishing.
