Abstract

Mangrove adalah tumbuhan yang mampu beradaptasi pada kondisi ekstrim utamanya pada daerah yang memiliki kadar garam tinggi. Identifikasi luasan hutan mangrove perlu dilakukan untuk mengetahui potensi sumberdaya yang ada disana. Hal ini dikarenakan mangrove sebagai tempat daerah asuhan (nursery grounds), tempat mencari makan (feeding grounds), dan daerah pemijahan (spawning grounds) berbagai jenis ikan. Tujuan dari penulisan jurnal ini adalah untuk mengetahui luas sebaran hutan mangrove pada Segara Anakan, Cilacap Jawa Tengah. Metode pengolahan citra satelit dengan cara digitasi menggunakan software ArcMap dan Envi tanpa melakukan validasi data ke lapangan. Analisa citra satelit  menggunakan perbandingan warna pada band NIR Citra satelit Landsat 8. Untuk membedakan mangrove dan non mangrove dengan melakukan  digitasi dan menghitung luas pada atribut tabel Arcmap. Hasil akhir terlihat luasan mangrove cilacap mencapai 12.005 Ha yang mengindikasikan terjadi perubahan luasan hutan mangrove dari tahun 2013 sebesar 4005 Ha.

Abstract

Oceanographic parameters that affect coral reef growth are clarity, temperature, salinity and water currents taken at 20 stations using AAQ Rinko 1183 and FLOWATCH FL-03 current meter. The data processing using the IDW (Inverse Distance Weighted) interpolation method and the determination of the suitability area through scoring and weighting. The identification value consist of: (a) Clarity ranges from 2 - 6 meters, (b) Water turbidity ranges from 0.3 - 4.32 NTU, (c) Bottom substrate type is fine black sand, (d) Current velocity ranges from 0.1 m/s - 0.4 m/s, and (e) TSS ranges from 35.6 - 351 mg / L. The suitability of placing artificial reefs is classified at the appropriate level (S2), as a support for the survival of fishermen and local communities in Damas Beach, Trenggalek Regency.

Abstract

Pantai Putri Menjangan, has good condition of coral reef, is located at Gerokgak District, Buleleng, Bali. Natural threat came from other inventebrate such as the coral eater, Acanthaster planci, that prey on coral tissue. A. planci is from family Acanthasteridae has 7-12 arms covered by toxic spines with 25-35 cm of body diameter. The aim of this research was to know abundance of A. planci at Pantai Putri Menjangan. To observed abundance of this creatures, we performed a belt transect 10x30 m in 5 stations. All A. planci inside of transect was count, note color and their diameter. We also record types of substrates and coral lifeform in this location. The study showed the abundance of A. planci in stations 1-3 was lower about 0.0067 individu/m2 and higher in station 5 was 0.03 individu/m2. In conclusion that no outbreak sign in this location.

Abstract

ABSTRACT Coral reef in Papuma was distributed in 3 to 20 m depth, with sand as main substrate. The coral reef was built from hard coral (scleractinian) and reef fishes. Papuma’s coral reef was interesting to be studied due to they can deal with the extreme environment such as high sand sedimentation, high wave, strong current, and anthropogenic risk. The purpose of this study was to descript distribution of hard coral and their fishes based on quantitative data in Papuma. We used Line Intercept Transect (LIT) method with 100 m long perpendicular with coast line to quantify of coral cover based on their life form. While reef fishes data was obtained using underwater visual census with 100 m long. All data was taken from 3 stasiun they were: station 1 (8°25'59.26"S 113°33'15.07"E), station 2 (8°26'0.93"S 113°33'17.53"E) and station 3 (8°26'2.02"S 113°33'20.06"E), in 3-12 m depth. The result showed that coral reef in Papuma was dominated by branching coral (CB) from genus Montipora with coral cover 30%, while sand (SD) to be main substrate with 26.9% of coverage. Montipora is one of genus famili Acroporidae that has faster growth than massive coral and strong branch as an adaptation strategy with strong current. In this research, we also found 137 of reef fishes that was 19% composed by indicator fish (Chaetodontidae). High number of indicator fish can represent of healthy coral reef. High coral cover coverage usually will be followed by increasing number of indicator fish. These fish were obligate corallivorous that consume coral polyp during their life. Coral reef in Papuma contained 10 types of life form and had coral cover about 39.9% in average.

Abstract

Terumbu karang merupakan ekosistem yang sangat kompleks dan memiliki peran penting bagi lingkungan di laut. Life form terumbu karang dipengaruhi oleh faktor lingkungan, salah satunya adalah kedalaman. Identifikasi life form dan pengukuran persentase tutupan karang di Pantai Tiga Warna perlu dilakukan, dengan menggunakan metode line intercept transect dan observasi lapangan. Hasil pengukuran life form di kawasan ini, baik di kedalaman 2 dan 5 meter, didominasi coral foliose. Persentase tutupan terumbu karang yaitu 43,83% yang menunjukkan bahwa kondisi ekosistem terumbu karang adalah cukup baik untuk mendukung ketahanan ekosistem di Pantai Tiga Warna.

Abstract

The objective of this research was to assess the condition and distribution of stony corals Scleractinian order at Karang Pakiman reef, Bawean Islands, Gresik. This research was conducted in May 2014. The biophysical conditions of coral reefs data were collected using line transect that placed on a line with the coastline, following the depth contours of the bottom waters and the geographical position was determined with GPS. The result showed that the condition of coral reefs in the study site was varied on the status of bad to good. Scleractinian coral in Karang Pakiman, Bawean spread over reef flat, reef crest, and reef slope zones. The main component of the coral reef at Karang Pakiman was Acroporidae, Faviidae, and Poritidae, while Poritidae and Faviidae family which were dominated by the coral massive (CM) life form and to be a constituent of coral reef ecosystems in the study site. The Diversity Index (H') was 1.72; Evenness Index (E) was 0.58, and Dominance Index (C) was 0.62. Penelitian ini bertujuan untuk menganalisis kondisi dan distribusi karang keras Ordo Scleractinia di gosong Karang Pakiman, Pulau Bawean, Gresik. Penelitian ini dilaksanakan pada Bulan Mei 2014 di perairan Pulau Bawean, Gresik. Metode yang digunakan dalam penelitian ini adalah metode penelitian survei / deskriptif. Materi penelitian adalah karang keras yang diidentifikasi sampai tingkat spesies. Pengumpulan data kondisi bio – fisik terumbu karang dilakukan dengan menggunakan transek garis dan transek kuadran yang diletakkan sejajar garis pantai, mengikuti kontur dasar perairan. Posisi geografis penelitian ditentukan dengan GPS. Hasil analisis memperlihatkan kondisi terumbu karang di lokasi penelitian berada pada status buruk sampai dengan baik. Karang keras di gosong Karang Pakiman, Pulau Bawean tersebar pada zona reef flat, reef crest, dan reef slope. Penyusun utama ekosistem terumbu karang pada lokasi penelitian terdiri dari 3 famili, yaitu Acroporidae, Faviidae, dan Poritidae. Life form CM yang didominasi oleh famili Poritidae dan Faviidae merupakan bentuk pertumbuhan utama karang keras penyusun ekosistem terumbu karang di lokasi penelitian. Nilai H’ adalah 1,72; nilai E adalah 0,58 dan nilai C adalah 0,62.
