Abstract

AbstrakPeran penting kerang Kima secara ekologis sebagai salah satu spesies kunci dalam ekosistem terumbu karang menyebabkan biota laut ini mengalami tekanan antropogenik di sebagian besar wilayah di Indo-Pasifik, termasuk Indonesia. Penelitian ini bertujuan untuk mengidentifikasi spesies Kima genus Tridacna asal Pulau Kur menggunakan markea gen COI dan menganalisis hubungan filogenetiknya. Sampel jaringan Kima diekstrak menggunakan kit ekstraksi komersial. Primer universal (LCO1490; HCO2198) dan primer spesifik Kima (LCO: 5’-GGG TGA TAA TTC GAA CAG AA-3’; RCO: 5’-TAG TTA AAG CCC CAG CTA AA-3’) digunakan untuk mengamplifikasi DNA target. Analisis data dilakukan terhadap 26 sekuen Kima asal Pulau Kur dengan panjang fragmen 479 bp menggunakan software MEGA6 meliputi analisis jarak genetik dan pohon filogenetik. Hasil analisis homologi menggunakan BLASTn mendapatkan empat jenis Kima, yaitu Tridacna maxima, T. crocea, T. noae, dan T. squamosa dengan similaritas 99–100%. Hasil penelitian menunjukkan bahwa jarak genetik dalam spesies sangat rendah berkisar 0,0000–0,0103 sedangkan jarak genetik antar spesies berkisar antara 0,0112–0,1729. Hasil konstruksi pohon filogenetik kerang Kima menunjukkan adanya dua klad utama yang kohesif dan jelas terpisah, yaitu kelompok Tridacna yang monofiletik dan Hippopus hippopus. Berdasarkan hasil penelitian, teknik DNA Barcoding sangat efektif untuk identifikasi dan mengkonfirmasi fenomena cryptic spesies.Abstract The role of the giant clam as the key and ecologically important species in coral reef ecosystem has led them to experience anthropogenic pressure in the most of Indo-pacific region including Indonesia. This research aimed to identify the species of giant clam Tridacna from Kur Island, Southeast Maluku by using COI gene marker and to analyze their phylogenetic relationship. The tissue sample of giant clam was extracted with a commercial extraction kit. Universal primer (LCO1490; HCO2198) and specific primer for giant clam (LCO: 5’-GGG TGA TAA TTC GAA CAG AA-3’; RCO: 5’-TAG TT AAG CCC CAG CTA AA-3’) was used to amplify DNA target. Twenty-six sequences from Kur Island with 479 bp fragment length were analyzed by using MEGA6 software. Homological analysis on BLASTn found four species i.e Tridacna maxima, T. crocea, T. noae, and T. squamosa with 99–100% similarity. The result also showed that genetic distance value intraspecies was very low ranging from 0.000 to 0.0105, while genetic distance inter-species ranged from 0.0112 to 0.1729. Reconstruction of phylogenetic tree of giant clam revealed two main group that cohesive and clearly separated i.e Tridacna group which monophyletic and Hippopus hippopuxs. Based on the result, the DNA barcoding technique was effective for identification and confirmation of the occurrence of cryptic species phenomenon.

Abstract

Rochia nilotica (Tegulidae) is a snail that is highly important economically due to its nacre layer on their shells. Lola shells are used as raw material in nail polish and high quality pearl buttons. Recently, the production of Rochia nilotica has drastically decreased. This study aimed to investigate the relationship on length-weight and condition factors of Rochia snails from four sites. Data collection was gathered on may-September 2021 at four sites i.e Kei Island, Morellla (Central Maluku), Sumbawa Island and Enggano Island with purposive sampling method. A total 177 individuals have been collected with a detail of 35 individuals from Kei Island, 61 Individuals from Central Maluku, 51 and 29 individuals from Sumbawa Island and Enggano island respectively.  The result showed that the relationship on length-weight of Rochia snails at Enggano Island, Sumbawa Island, central Maluku and Kei Island was  W=0,00707L2,2804, 0,00686L2,3949, 0,00308L2,5478,dan 0,00025L3,0893 respectively. The result shows that the growth pattern at Bengkulu, Sumbawa, and Morella follows a negative allometric model, while those at Kei Islands follow a positive allometric. Condition factors were relatively varied 1,0020-1,0317 suggested that the research waters were still a suitable environment for the growth of top shells.   Siput lola Rochia nilotica (Tegulidae) merupakan komoditi niaga bernilai ekonomis tinggi karena cangkangnya yang memiliki lapisan mutiara. Cangkang siput lola digunakan sebagai bahan baku industri cat kuku dan kancing yang berkualitas tinggi. Akibat eksploitasi berlebihan, produksi siput lola mengalami penurunan drastis selama beberapa tahun terakhir. Penelitian ini bertujuan untuk menentukan hubungan panjang berat dan faktor kondisi dari siput lola di 4 lokasi penelitian yang dipilih. Pengambilan data dilakukan pada bulan April-September 2021 dengan menggunakan metode Purposive Sampling yang dilakukan di 4 lokasi yaitu Kepulauan Kei, Morella, Pulau Sumbawa, dan Pulau Enggano yang mewakili 3 wilayah (Timur, Tengah dan Barat) Perairan Indonesia. Siput Lola yang diperoleh sebanyak 177 individu yang berasal dari 35 individu dari Kepulauan Kei, 61 individu Morella, 51 individu Sumbawa, dan 29 individu Enggano. Hubungan panjang berat siput lola di lokasi penelitian Enggano, Sumbawa, Morella, dan Kepulauan Kei secara berurutan yaitu sebesar W=0,00707L2,2804, 0,00686L2,3949, 0,00308L2,5478,dan 0,00025L3,0893. Hasil penelitian ini menunjukkan bahwa pola pertumbuhan siput lola di Pulau Enggano, Sumbawa dan Morella mengikuti model allometrik negatif, sedangkan pola pertumbuhan siput lola di Kepulauan Kei mengikuti model allometrik positif. Faktor kondisi relatif beragam dari 1,0020-1,0317 yang mengindikasikan bahwa daerah perairan penelitian masih merupakan lingkungan yang sesuai untuk pertumbuhan siput lola.
