Abstract

  Penelitian mengenai Echinodermata sudah banyak dilakukan, namun di Pulau Panikiang, masih sangat terbatas, sehingga perlu dilakukan penelitian lebih dalam mengenai keanekaragaman Echinodermata. Telah dilakukan penelitian mengenai Echinodermata dengan menggunakan line transect kombinasi plot. Dimana panjang line transect 50 m dan plot dengan ukuran 2 x 2 m. Echinodermata yang berada dalam plot dihitung jumlah individunya, diamati morfologinya, diambil gambarnya untuk identifikasi lebih lanjut. Dilakukan analisis data keanekaragaman jenis, kemerataan, persebaran jenis dan dominansi. Ditemukan 10 species Echinodermata, yang terdiri dari 8 genera dan 8 famili. Memiliki tingkat keanekaragaman Echinodermata tergolong bervariasi (0.122251 - 2.014903).   Kata Kunci: Echinodermata, Pulau Pannikiang, Ekosistem Lamun

Abstract

The Research on “Coral Coverage in Baranglompo Island and Bone Batang Island Based on Reef Check Method” was conductedin April 2016. The aims of this study was to determine and to compare the condition of reefs in Baranglompo and Bone BatangIslands based on the percentage of life coral cover by using Reef Check methods. This study also aims to determine whichfactors that most affect the percentage of coral cover on each island i.e: abiotic factors (temperature, salinity and substrate inthe form of rock, rubble, sand, silt/clay); biotic factors (soft coral, recent killed coral, algae, sponges, fish and invertebratesassociate) and anthropogenic factors (garbage, ilegal fishing/bombs, stun, anchors, nets) were also investigated. Percentage oflife coral cover obtained by Line Intercept Transect (LIT) along 100 meters at a depth of 3 meters and 10 meters. The resultsshowed that the condition of coral reefs in Baranglompo was classified as moderate with an average percentage coral coverageof 42% at a depth of 3 meters and 27% at a depth of 10 meters. While the condition of coral reefs in Pulau Bone Batang wasrelatively good with average coral cover of 51% at 3 meters depth and moderate with average coral cover of 39% at 10 metersdepth. Condition of coral reefs in Bone Batang is better than Baranglompo islands. Anthropogenic impacts in the form of wasteis the most influential factor on coral cover on the island Baranglompo. Whereas fishing activities by using dinamite are thefactors that most influence on coral cover on the island of Bone Batang.Keywords: Coral coverage, Baranglompo island, Bone Batang island, Reef Check

Abstract

The study aims to know the biodiversity and community structure of marine tunicate in Samalona waters. The present study is part of biodiversity assessment for marine resources of Sangkarang Archipelago SW Makassar Indonesia. Field campaign was conducted from October to November 2016. Sample collection was done at 3 and 7 m depth by using Line Intersection Transect (LIT) method combined with a quadrat (plot). Two 50 m transects were placed parallel to a shore line at three stations (sta.) at Samalona waters. A quadrat (plot) (2.5 m x 2.5 m) was placed side by side of the line transect and all tunicates in the transect was recorded, identified, counted and photographed. Samples were collected by using SCUBA and under water camera. Environmental parameters including water temperatue, salinity, dissolved oxygen, clarity, current and wind speed, were measured in situ. Data were analysed using ecological indices including species composition and density, Shanon Wienner species diversity, Evenness, and Morisita Indices. The result indicates that there are 18 species of tunicates present at 3 m as well as 7 m depth of Samalona waters.. Result of the ecological analysis shows that species diversity can be categorized as moderate and there were no dominant species. Environmental parameters indicates that water quality at Samalona waters was in good condition to support tunicates.

Abstract

Penelitian tentang “Genera Karang Keras Di Pulau Barranglompo Dan Bonebatang Berdasarkan Metode Identifikasi Coral Finder” telah dilakukan pada bulan Januari hingga April 2016. Penelitian ini bertujuan mengetahui variasi genera karang keras yang ada di Pulau Barranglompo dan Pulau Bonebatang. Pengambilan data dilakukan dengan metode “Line Intercept Transect (LIT)”, di sisi selatan, barat dan utara masing – masing pada kedalaman 3 dan 10 m. Penentuan genera karang dilakukan berdasarkan metode identifikasi Coral Finder. Hasil penelitian menunjukkan bahwa pada kedalaman 3 m genera karang yang ditemukan di Pulau Bonebatang (31 genera) lebih banyak dibandingkan dengan Pulau Barranglompo (24 genera). Kondisi sebaliknya ditemukan pada pada kedalaman 10 m jumlah genera karang di Pulau Barranglompo (29 genera) lebih tinggi dibandingkan dengan Pulau Bonebatang (27 genera). Genera yang paling umum ditemukan pada kedalaman 3 m di Barranglompo yaitu Acropora, Fungia,dan Porites. Sedangkan di Pulau Bonebatang ditemukan pada genera Ctenactis, Fungia, Pachyseris danPorites. Pada kedalaman 10 m, genera karang yang paling dominan di Pulau Barranglompo adalah Acropora dan Fungia. Sedangkan di Pulau Bonebatang didominasi olehAcropora, Fungia, dan Seriatopora. Dampak antropogenik di Pulau Barranglompo didominasi oleh pembuangan sampah sedangkan Pulau Bonebatang dipengaruhi oleh aktifitas pengeboman ikan. Kata Kunci: Genera Karang, Coral Finder Pulau Barranglompo, Pulau Bonebatang, Spermonde.
