Penelitian ini bertujuan untuk mengetahui kelimpahan dan keanekaragaman fitoplankton serta hubungannya dengan parameter fisik-kimia perairan. Penelitian telah dilakukan pada bulan Desember 2014 di Laguna Leupung. Pengambilan sampel plankton dilakukan pada 6 stasiun pengamatan dengan menggunakan plankton-net. Identifikasi plankton dilakukan di Laboratorium Fakultas Kelautan dan Perikanan, Universitas Syiah Kuala. Genus yang ditemukan sebanyak 25 genera yang berasal dari kelas Bacillariophyceae, Dinophyceae dan Cyanophyceae. Kelas Bacillariophyceae tergolong sedang dengan kelimpahan rata-rata 1202,02 ind./l, sedangkan kelas Dinophyceae berkisar 621,13 ind./l dan Cyanophyceae 208,49 ind./l yang tergolong dalam kelimpahan rendah. Genus yang dominan ditemukan adalah Rhizosolenia sebesar 26%. Nilai indeks Keanekaragaman berkisar 1,88 - 2,63, dan termasuk kedalam kategori sedang. Berdasarkan Principal Component Analysis diketahui parameter fisik-kimia berpengaruh terhadap kelimpahan fitoplankton di perairan Laguna Leupung.

Abstract. The aimof this study was to evaluate the condition of coral reefs and macro invertebrates at Ujong Pancu, Aceh Besar District The study was carried out from April to May 152012. Coral coverage was observed by using Point Intercept Trancect method and Visual census technique for macro invertebrates. There was 50% of hard coral coverage recorded in three observation locations. The predominant genus was Acropora with a percentage of more than 50% at all locations. The abundance of macro invertebrateswas ranged from 3.75 to 7.75 ind/transect. The most abundant macro invertebrates was Diadema setosum with percentage of more than 40% at each location. The diversity index (H’) of coral reefs and macro invertebrates were ranged from 0.74 - 1.36 and 0.98 – 1.5, respectively. In general, the condition of coral reefs and macro invertebrates in Ujong Pancu was in good condition. Keywords: Coral reefs; Macro invertebrates; Ujong Pancu. Abstrak. Penelitian ini bertujuan untuk mengetahui kondisi terumbu karang dan makro invertebrata di Ujong Pancu. Penelitian ini dilakukan pada bulan April hingga Mei 2012. Tutupan karang diamati dengan menggunakan Metode Point Intercept Transect (PIT) dan makro invertebrata diamati dengan menggunakan metode TeknikVisual Sensus. Hasil penelitian ditemukan bahwa lebih dari 50% tutupan karang keras pada ketiga stasiun pengamatan. Genus yang paling mendominasi pada ketiga stasiun adalah Acropora dengan persentase lebih dari 20% pada setiap stasiun pengamatan. Kelimpahan makro avertebrata berkisar antara 3,75 hingga 7,75 ind/transek. Kelimpahan makro invertebrata terbesar adalah Diadema setosum dengan persentase lebih dari 40% pada setiap stasiun pengamatan. Indeks keanekaragaman (H’) karang dan makro investebrata berkisar antara 0,74 - 1.36 dan 0,98 – 1,5 secara berurutan. Secara umum berdasarkan indeks yang digunakan, kondisi terumbu karang dan makro invertebrata di Ujong Pancu tergolong baik.Kata kunci : Terumbu Karang; Makro avertebrata; Ujong Pancu.

The aims of this research was to knew the prevalence, abundance and types of coral diseases detected in Peukan Bada Aceh Besar Regency. Method used in this research was a 20x2m belt transect with 3 replicates. Results show that the prevalence value was between 27,94% – 58,25%. The value was quite higher if compared with other prevalence on some place in indonesia. Average value of coral disease abundance in this research was 0,23 ind/m2. There was 13 types of coral disease found during sampling, including Fish Bite, Drupella Predation, Acanthaster planci Predation, White Syndrome, Ulcerative White Spot, Focal Bleaching, Non-Focal Bleaching, Invertebrate Galls, Sponge Overgrowth, Cyanobacteria, Pigmentation Response, Sedimentation Damage, Algae Overgrowth. The most infected coral genus was Acropora with branching growth form.Keywords:AbundanceConditionCoral diseasePrevalence

Abstrak. Wilayah Pesisir Utara Aceh Besar memiliki kekayaan jenis vegetasi mangrove yang terdapat di kawasan ini. Saat ini data indeks nilai penting dan keanekaragaman jenis vegetasi di Aceh Besar khususnya di Pesisir Utara Aceh Besar sedikit tersedia. Metode penelitian ini menggunakan metode purposive sampling. menurut pengamatan yang dilakukan di lokasi penelitian. Berdasarkan penelitian yang telah dilakukan pada kawasan pesisir utara Aceh Besar, jumlah jenis mangrove yang ditemukan yaitu 8 jenis Avicennia marina, Aegiceras corniculatum, Bruguiera gymnorrhiza, Excoecaria agallocha, Rhizophora apiculata, Rhizophira mucronata, Rhizophora stylosa dan Xylocarpus granatum. Dalam penelitian ini nilai INP paling tinggi yaitu spesies Rhizophora mucronata pada kategori pancang yaitu 224,29%. Kata kunci : Indeks nilai penting, Keanekaragaman jenis , Vegetasi mangrove. Abstract. The North Coast region of Aceh Besar has a wealth of mangrove vegetation species found in this area. Currently there is little data on the importance value index and the diversity of vegetation types in Aceh Besar, especially on the North Coast of Aceh Besar. This research method uses purposive sampling method. according to observations made at the study site. Based on research conducted in the northern coastal area of Aceh Besar, the number of mangrove species found was 8 species of Avicennia marina, Aegiceras corniculatum, Bruguiera gymnorrhiza, Excoecaria agallocha, Rhizophora apiculata, Rhizophira mucronata, Rhizophora stylosa and Xylocarpus granatum. In this study, the highest INP value was Rhizophora mucronata species in the sapling category, namely 224.29%. Keywords: Importance value index, species diversity, mangrove vegetation.
