Abstract

Abstract: The mole crab (Hippidae) is a filter feeder organism from crustacean that inhabits in sandy coastal areas. Due to its nature, this organism is able to accumulate heavy metals in a large amount. The concentration of heavy metals in this organism will increase in line with the polluting condition of its habitat. Heavy metals which exceed the standard in the organism body will be implicated to the human health who consumes the organism. The sandy crabs are found in large amount in Widara Payung coastline, Cilacap Regency. They are captured by the locals for meals. The heavy metal content such as Lead in the organism body never been investigated in this area previously. This research aimed to estimate the health risk of people who consume the sandy crabs in the area of Widara Payung, Cilacap Regency. This research was conducted on April to May 2018 and a location of sampling was determined purposively. Samples consisted of three types namely sandy crab body, sediment, and seawater. Each sample was preserved in an ice box and then transported to Aquatic Productivity and Environment Laboratory in Bogor Agricultural Univeristy for heavy metal analyzing. Results of this research exhibited that the average of Lead content in the water, sediment, and body of the sandy crab were 0.007 mg/l, 43.43 mg/kg, 0,97 mg/kg, respectively. The Lead content in the crab body the standard issued by the government of Indonesia through the BPOM, namely 0.20 mg/kg. Regular monitoring of Pb concentration in the mole crab and its habitat is suggested.  Keywords: consumption, Emerita emeritus, Hippidae, intertidal, pollution  Abstrak: Undur-undur laut (Hippopidae) adalah crustacea filter feeder yang hidup di daerah pantai intertidal berpasir. Karena sifatnya, organisme ini mampu mengakumulasi logam berat dalam jumlah besar. Konsentrasi logam berat dalam organisme ini akan meningkat sejalan dengan kondisi polusi habitatnya. Logam berat yang melebihi standar dalam tubuh organisme akan berimplikasi pada kesehatan manusia yang mengkonsumsi organisme tersebut. Undur-undur laut dapat ditemukan dalam jumlah besar di pesisir Widara Payung, Kabupaten Cilacap. Mereka ditangkap oleh penduduk setempat untuk dikonsumsi. Kandungan logam berat seperti Pb dalam tubuh undur-undur laut belum pernah diteliti di daerah ini sebelumnya. Penelitian ini bertujuan untuk menentukan konsentrasi timbal (Pb) pada undur-undur laut dan implikasinya terhadap kesehatan manusia bila mengkonsumsinya di daerah Widara Payung, Kabupaten Cilacap. Penelitian dilakukan pada bulan April sampai Mei 2018 dan lokasi pengambilan sampel ditentukan secara purposif. Sampel terdiri dari tiga jenis yaitu undur-undur laut, sedimen, dan air laut. Setiap sampel yang diambil disimpan dalam kotak pendingin dan kemudian dibawa ke Laboratorium Produktivitas dan Lingkungan Perairan di Institut Pertanian Bogor untuk analisis logam berat. Hasil penelitian ini menunjukkan bahwa rata-rata kandungan Pb dalam air, sedimen, dan undur-undur laut masing-masing adalah 0,007 mg/l, 43,43 mg /kg, 0,97 mg/kg. Kandungan timbal dalam undur-undur laut telah melampaui standar yang telah dikeluarkan oleh pemerintah Indonesia melalui BPOM yaitu 0,20 mg/kg. Dengan nilai tersebut, konsumsi undur-undur laut memiliki resiko kesehatan pada manusia. Monitoring kandungan logam di lingkungan habitat dan pada undur-undur laut menjadi prioritas.  Kata kunci: Emerita emeritus, Hippidae, intertidal, konsumsi, pencemaran

Abstract

Abstrak : Variasi bentuk dan pola pewarnaan tubuh ikan kerapu (Famili Serranidae) sangat variatif, sehingga pengenalan spesies secara morfologis sering tidak akurat. Penelitian ini bertujuan untuk mengautentikasi ikan kerapu dengan menggunakan marka gen COI. Contoh ikan kerapu yang diamati berjumlah 29 ekor yang dikumpulkan dari tiga tempat pendaratan ikan di Perairan Peukan Bada, Propinsi Aceh. Secara karakter morfologis, ikan kerapu tersebut teridentifikasi lebih dari 8 spesies. Untuk analisis DNA, sebanyak 30 mg daging sirip dari setiap ikan contoh diambil untuk dilakukan isolasi dan ekstraksi DNA, kemudian visualisasi elektroforesis dan fragmentasi DNA gen COI dengan metode PCR-sekuensing. Setelah diekstraksi, diperoleh 20 sampel DNA yang tervisualisasi dengan baik, yang dari jumlah tersebut terdapat 16 sampel dapat diamplifikasi. Hasilnya menunjukkan terdapat 6 spesies yang terautentikasi. Kelompok pertama adalah Variola albimarginata, Cephalopholis urodeta, dan C. sexmaculata dengan tingkat kemiripan ≥ 97%. Berikutnya C. boenak, Epinephelus merra, dan Scolopsis vosmeri tingkat kemiripannya ≤ 97%. Bila dibandingkan hasil autentikasi DNA, hasil penelitian menunjukkan bahwa 13 sampel atau > 80% tidak teridentifikasi dengan benar secara morfologis. Berdasarkan jarak genetik, pohon filogeni membentuk 2 clade antara Serranidae dan Nemipteridae. Hasil penelitian menunjukkan bahwa penggunaan marka gen COI sangat efektif untuk autentikasi spesies yang dapat dijadikan sebagai instrumen dalam pemanfaatan dan pengelolaan ikan kerapu.Kata kunci : kerapu, variasi morfologi, gen MT-COI, autentikasi.Abstract : The groupers (family Serranidae) show high variability both in body shapes and coloration leads to highly morphological-based misidentification. The research was aimed in autenthication of the grouper species using MT-COI gene. A total of 29 grouper fishes were collected from three fish landing sites of Peukan Bada, Aceh Province. These fishes were morphologically identified from which more than 8 species were obtained. A 30 mg of the fin meat of each sample was taken for DNA extraction, isolation, electrophoresis visualization, and DNA fragmentation of COI gene using PCR-sequenching.  There were 20 DNA samples was clearly visualized of which 16 has been proceeded for amplification. The results showed that V. albimarginata, C. urodeta, and C. sexmaculata showed ≥ 97% similarity, whereas C. boenak, E. merra, dan S. vosmeri with ≤ 97% similarity. Based on phylogenetic tree analysis there was 2 clearly different clades separating family of Serranidae and Nemipteridae. The use of MT-COI gene was effective and accurate tool in species authentication which could be used as an instrument for utilization and management of the grouper species.Keywords : groupers, morphological variation, MT-COI gene, autenthication.

Abstract

Freshwater crayfish (Cherax quadricarinatus) as an invasive species has high capability to adapt in most waters in Indonesia. The extant distribution of this species in Indonesia causes observation of morphological characters  is important to be established. This study purpose is to compare the morphological characters of Cherax quadricarinatus from several locations in Indonesia waters, such as the river in Bintan Island, Toba Lake, and Lido Lake. The total of morphological characters was measured in twenty-two characters. The result of the Kruskal-Wallis test represented nine different characters between Toba, Bintan, and Lido. Cluster analysis illustrated the highest level of similarities between Toba and Lido. The growth rate of the dactyls, and carapace width, and ocular carapace length between Toba and Lido were similar, meanwhile between Toba and Bintan were different. C. quadricarinatus originating from river waters in Bintan Island has a different morphological character from Lake Lido and Lake Toba. The differences in morphological characters between locations are caused by differences in habitat characteristics in rivers and lakes.
