"Penelitian mengenai kondisi tutupan karang di perairan Pulau PanjangBesar, Kepulauan Seribu telah dilakukan pada tanggal 9--13 November 2005.Penelitian ini bertujuan untuk mengetahui kondisi tutupan karang di PerairanPulau Panjang Besar, Kepulauan Seribu. Penelitian dilakukan denganmenggunakan metode Line Intercept Transect. Hasil penelitian menunjukkankondisi terumbu karang pada kedalaman 3 m berada dalam kondisi rusak(tutupan 10,86--16,10%) kecuali di sisi Barat Laut (43,31%) yang beradadalam kondisi sedang. Terumbu karang pada kedalaman 8 m berada dalamkondisi rusak dengan angka tutupan tertinggi di sisi Barat Daya (14,86%).Bentuk koloni bercabang mendominasi pada kedalaman 3 m dan bentukkoloni masif mendominasi pada kedalaman 8 m. Kondisi tutupan karang disebagian besar perairan Pulau Panjang Besar berada dalam kondisi rusak,sedangkan lokasi yang memiliki kondisi sedang adalah sisi Barat Laut."

ABSTRACTCoral reef cover has been conducted observations using the Line Intercept Transect (LIT), and methods of Under water Fish Visual Census (UVC) to determine the type of fish Observation of the condition of coral reefs and reef fish is done in shallow water which is 3-6 depth in ten-point observation station. Based on direct observtion, the general condition of coral reef in Wangi-wangi Island is classied into the category from moderate to good. The average peresentage of live coral cover (life form) at the base station to station 10 is 64,61%. Water temperature ranged from 25 until 29oC, Salinity 34-36?, Brightness reaces the bottom; diversity index (H?) ranged from 3,2 to 3,6. Uniformity index (E) at te bottom waters ranged from 0,83 to 0,91. Dominance Index (C) ranged from 0,09 to 0,14. Reef fish diversity index ranged from 2,96 to 3,97, Uniformity index (E) reef fish ranged from 0,55 to 0,97. Valve dominance index (C) ranged from 0,04 to 0,17. Based on the valve of scoring on te whole category, all of the observation stations are include in category S1 which is suitable for beach tourism or nautical tourism like diving or snorkling.;Coral reef cover has been conducted observations using the Line Intercept Transect (LIT), and methods of Under water Fish Visual Census (UVC) to determine the type of fish Observation of the condition of coral reefs and reef fish is done in shallow water which is 3-6 depth in ten-point observation station.

"Penelitian bertujuan untuk membandingkan tingkat akurasi dan efisiensi penggunaan metode Foto Kuadran sebagai metode digital dalam menghitung persentase luasan tutupan karang dibandingkan metode LIT (Line Intercept Transect) sebagai metode visual. Data diambil dengan tiga kali pengulangan dengan jarak total 100 m. Titik pertama adalah jarak 0 m--30 m, titik kedua adalah jarak 35 m--65 m, dan titik ketiga adalah 70 m--100 m. Data diambil di dua stasiun dengan dua kedalaman, 3 m dan 7 m. Tutupan karang di kedalaman 3 m lebih tinggi dibandingkan dengan kedalaman 7 m. Hasil penelitian ini menunjukkan bahwa pengambilan data lapangan menggunakan metode LIT memerlukan waktu yang lebih lama dibandingkan dengan metode Foto Kuadran. Waktu yang digunakan untuk pengolahan data dengan metode LIT lebih sedikit dibandingkan dengan metode Foto Kuadran. Hasil persentase tutupan karang dengan metode LIT lebih tinggi dibandingkan dengan metode Foto Kuadran. Persentase tutupan karang dengan kedua metode diuji dengan Paired Sample TTest dan menghasilkan kesetaraan nyata. Metode Foto Kuadran lebih akurat dan efisien dalam pengambilan data jangka panjang. Persen tutupan karang Desa Gondol hingga 51,5 %, termasuk kedalam kategori baik.

This research is aiming to compare efficiency and accuracy of LIT (Line Intercept Transect) Method and Photo Quadrat as digital methods to calculate coral cover percentage. Data were taken in 3x repetitions with total length of 100 m. First sample point was 0 m--30 m, second sample point was 35 m--65 m, and third sample point was 70 m--100 m. Data were taken in two stations with two depths respectively, 3 m and 7 m. Coral cover in 3 m depth is higher than in 7 m depth. Results indicate that field data sampling using LIT method require longer periods than Photo Quadrat method. LIT method needs shorter period than Photo Quadrat method to analyze data. LIT method generates higher coral cover percentage than Photo Quadrat. Coral cover percentages of those two methods were examined using Paired Sample T-Test and obtain high similarity. Photo quadrat method is more accurate and efficient than LIT method in long term research. Coral cover percentage in Gondol is 51,5 %, included in good category."
