Abstract

Terumbu karang merupakan ekosistem yang kompleks dengan karagaman biologi tinggi yang mendukung hasil perikanan dan melindungi pantai dari aksi gelombang. Pasca bencana tsunami pada 26 Desember 2004 silam, belum banyak informasi kuantitatif mengenai kondisi terumbu karang di sekitar perairan Pulau Weh Sabang Nanggroe Aceh Darussalam. Penelitian mengenai kondisi terumbu karang ini dilakukan di enam stasiun pengamatan yang tersebar di bagian barat, tengah dan timur Pulau Weh dengan menggunakan Metode Transek Garis (LIT, Line Intercept Transect) berdasarkan bentuk pertumbuhan (life form) karang dankomponen benthik lainnya. Hasil penelitian memperlihatkan kondisi terumbu karang di perairan Pulau Weh masih baik, seperti di stasiun Benteng, Lhong Angen dan Gapang, namun di beberapa tempat telah memperlihatkan kerusakan mengkhawatirkan yang diperkirakan bukan akibat bencana tsunami, namun karena adanya usaha pemanfaatan sumberdaya alam tidak ramah lingkungan. Tidak ditemukan kerusakan yang serius akibat bencana tsunami terhadap ekosistem terumbu karang diperairan Pulau Weh diperkirakan berhubungan dengan tipe pantai yang pada umumnya berbatu, terjal dan sangat kokoh serta didukung oleh kondisi terumbu karang yang baik sehingga mampu menahan dan meredam aksi gelombang melalui sistem spur and groove.Kata kunci : terumbu karang, Sabang, LIT, tsunamiCoral reefs are complex ecosystems with high biological diversity that support productive fisheries and protect the beach from wave action. After tsunami disaster on last 26 December 2004, there is noquantitative information yet on condition of coral reef ecosystem around Sabang waters, Weh Island,Aceh, Indonesia. This research has been done in sixt station of Weh Island on early April 2005. LineIntercept Transects (LIT) are used to assest the sessile benthic community of coral reef. The community is characterized using lifeform categories which provide a morphological description of the reef community. The result shows that coral reef condition in Sabang Waters, Weh Island, generally is good, especially in Benteng, Lhong Angen and Gapang stations. However, in some sites coral reef condition are bad. There is no serious impact because of tsunami disaster on coral reef condition in Sabang Waters. The bad coral reef condition in some sites may be because of illegal fishing. Rocky shore and good coral reef condition are main factors which protect the beach ecosystem from wave action. Spur and groove system of the coral reef structure acts primarily as a dissipator of the continual wave energy operating on the coastal shoreline, and by dissipating wave energy before it reaches the shore, the beach area is protected from extensive wave action of tsunami.Key words: coral reef, Sabang, LIT, tsunami

Abstract

This research studied the application of chitosan on salted mackerel (Rastrelliger sp.) preservation during storage at room temperature. The research is aimed to study the effect chitosan concentration and storage time for Total Plate Count (TPC). The study was conducted in Laboratory of Microbiology, Faculty of Mathematics and Natural Sciences, Syiah Kuala University from April to August 2012. The research method was laboratory experimental.  The data was analyzed by Randomized Completely Design with two factorial. The first factor was chitosan concentration (three levels: 0%; 1%; 2%) while the second factor was storage time (four levels: 0; 2; 4; 8 weeks). The results of this study indicated that chitosan concentration was not significantly different for the Total Plate Count (p 0,05), however storage time was significantly for the Total Plate Count (p 0,05). Futhermore, the interaction chitosan concentration and storage time was significantly for the Total Plate Count (p 0,05).

Abstract

Penelitian ini dilaksanakan di ekosistem terumbu karang Kepulauan Seribu DKI Jakarta dengan tujuan untuk mengkaji kemampuan (affinitas) rekrutmen karang (Ordo Scleractinia) pada tiga jenis substrat keras berbeda, yaitu semen, genteng dan batu kapur. Substrat penempelan berukuran 20 x 20 x 3 cm3 diletakkan secara vertikal pada rak yang ditanam di dasar perairan dengan kedalaman 5 m. Substrat ditempatkan di dalamperairan selama tiga bulan, kemudian diambil dan dibawa kelaboratorium untuk diidentifikasi serta dihitung jumlah rekruit karang yang menempel. Hasil penelitian menunjukkan bahwa terdapat perbedaan affinitas rekrutmen karang pada tiga substrat yang dicobakan. Affinitas terbaik adalah substrat batu kapur yang ditandai kelimpahan rekruit paling tinggi dibandingkan substrat lain. Selama penelitian ditemukan enam spesies rekruit karang pada ketiga jenis substrat, yaitu: Pocillopora damicornis, Seriatopora hystrix dan Stylophora pistillata dari Famili Pocilloporidae; Acropora millepora dan A. tenuis dari Famili Acroporidae, dan; Porites sp. dari Famili Poritidae. Kelimphan spesies P. damicornis dominan pada ketiga jenis substrat. Kondisi terumbu karang di lokasi penelitian (Pulau Payung) tergolong baik dengan tutupan karang keras 67%, sedangkan dilokasi sekitarnya yaitu Pulau Pari tergolong sedang (36%) dan Pulau Lancang tergolong buruk (15%).Kata kunci: rekrutmen, karang, substrat penempelan.

Abstract

Penelitian tentang perbedaan jenis pakan dan jumlah ransum harian kepiting bakau (Scylla serrata) telah dilakukan yang bertujuan untuk mencari pakan alternative dan jumlah pakan harian yang sesuai untuk budidaya kepiting bakau. Metode yang digunakan adalah eksperimen lapangan dengan dua factor perlakuan yaitu perbedaan jenis pakan (ikan rucah, usus ayam dan keong mas) dan jumlah ransom harian (10%, 15%, 20%). Kepiting dipelihara dalam keramba jaring (1m x 1m x 1m) dengan padat tebar 9 ekor/karamba dan dipelihara selama enam minggu. Hasil penelitian menunjukkan bahwa perbedaan jenis pakan dan jumlah ransom harian tidak mempengaruhi secara nyata pertumbuhan dan kelangsungan hidup kepiting bakau.Namun demikian, ikan rucah sebayak 20% memberikan hasil pertumbuhan yang lebih tinggi dibandingkan jenis pakan lainnya. Sementara itu, angka kelangsungan hidup yang tinggi diperoleh pada pemberian keong mas 10% dan 15%.Dengan demikian dapat disimpulkan bahwa pemberian keong mas and usus ayam dapat digunakan sebagai pakan alternative dalam budidaya kepiting bakau, namun demikian pemakaian ikan rucah sebagai pakanmemiliki peran penting dalam budidaya kepiting.Kata kunci : Kepiting bakau (Scylla serrata), keong mas (Pomacea canaliculata), ikan rucah dan usus ayamThe study of feed differences and feeding ration of mud crab (Scylla serrata) on the growth, and survival rate was done. The objective of the present study is to find alternative feeds and daily rations for mud crabculture. Field experimental was used in this study and two factors were evaluated namely type of feed (trash fish, chicken intestine and golden snail) and daily ration of 10%, 15% and 20%. The crabs were reared in poly ethylene cages with stocking density of 9 crabs /cage for six weeks. The result shows that the differences of feed types and daily rations were no significant affected on growth performance and survival rate of mudcrab. However, feed of trash fish 20% have resulted in a higher growth performance than other feeds and higher survival rates were found at feed of golden snail 10% and 15%. Therefore, it is concluded that goldensnail and chicken intestine are possible to be used as alternative feeds for mud crab culture. However trash fish is still play a vital role in crab culture.Key words: Mud crab (Scylla serrata), golden snail (Pomacea canaliculata), trash fish and chicken intestine.

Abstract

Abstract-. Coral transplantation is one of the techniques to rehabilitate the damaged coral reefs. The objective of this study is to observe the composition of reef fishes in the coral transplantation location in Rubiah Island, Sabang. The study was conducted in February 2011. Some of reef fishes Family were found in coral transplantation location (16 Family at 3 meters and 14 Family at 10 meters). The Family of Acanthuridae, Chaetodontidae, Pomacentridae Scaridae and Labridae were found in 3 meters. Reef fish families that dominated at depths of 10 meters were the Family of Acanthuridae, Pomacentridae Scaridae and Chaetodontidae. There are 40 reef fish species found in this study (34 species in 3 m and 38 species in 10m). Some reef fishes that were found in the transplantation area suggested that coral reefs rehabilitated using the technique of transplantation can improve its function as habitat for reef fish.Keywords: Transplantation, coral reefs, Rubiah Island
