Abstract

Turtles are marine reptiles that inhabit seagrass ecosystems and are able to migrate deeply along the Indian Ocean, Pacific Ocean to Southeast Asia. Turtles are scattered in tropical and subtropical waters mostly found in Indonesian waters, especially in Aceh waters. The west coast of Aceh Besar, especially Pulo Aceh currently has potential as a residence for several turtle populations. Some of the turtle species that often lay their eggs on this beach are turtles, leatherback turtles and green turtles. The purpose of this dedication is to provide understanding to the Pulo Aceh Ecotourism Institute (LEPA) and communities around Pulo Aceh to understand the importance of turtle conservation, and to implement turtle breeding techniques for ecotourism development in good Pulo Aceh and sustainability. This devotional activity is carried out for two days, ie from Saturday to 10 March to Sunday 11 March 2018 held at Gugop Beach, Pulo Aceh, Aceh Besar District, Aceh Province. The approach taken in this activity is the persuasive socialization and the direct practice of turtle conservation techniques and the release of sea turtles attended by tourists from various regions, government agencies, non-governmental organizations and academics in Aceh. Turtle turtles are released as much as 270 head of 480 total tail, which consists of 2 types; namely Turtle Lekang as many as 353 heads, which released 170 tails. While the green turtle of 127 tails, which is released only 100 tails. The abandoned hatchlings are in a breeding location aimed at ecotourism and research for academics to conduct research on these endangered and endangered animals.

Abstract

Plastic waste is one type of waste that is very dominant in its use in everyday life. The nature of plastic that is light, strong, durable and cheap causes the use of plastic to continue to increase, from the nature of this plastic it makes plastic very dangerous for the environment which has the potential to be a contaminant, besides that plastic has properties that are not easily decomposed in soil and water, so it can settle and accumulated over a long period of time. The Pulot Beach area is one of the tourist attractions in Aceh Besar, with beautiful natural panoramas and the potential for fisheries in this area is also very potential, so many people visit this area. The high number of tourists visiting the Pulot area can have a negative impact in the form of plastic waste that has the potential to reduce the quality of the coastal and marine environment as well as the preservation of the surrounding environment. The purpose of this service is to provide understanding, knowledge and direction to the coastal community of Gampong Pulot the importance of human awareness of the cleanliness of the sea by not throwing garbage on the beach. This service activity is carried out for one day, namely on Thursday, October 28, 2021 at 09:00 to 12:00 WIB, located at Pulot Beach, Leupung District, Aceh Besar Regency. persuasive education and direct practice on how to collect waste, and sort plastic waste and weigh waste. The output obtained after this service activity is the emergence of awareness and initiative from the community and visitors not to throw plastic waste carelessly, so that the preservation of healthy beaches and seas is free from plastic waste.

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

Krustasea merupakan suatu kelompok besar dari filum Arthropoda yang terdiri dari lebih kurang 52.000 spesies yang sebagian besar hidup di perairan sungai, estuari dan laut. Penelitian ini bertujuan untuk menganalisis komposisi jenis hasil tangkapan krustasea nelayan di PPI Rigaih Kabupaten Aceh Jaya. Pengumpulan data dilakukan dengan survei lapangan di lokasi pendaratan ikan PPI Rigaih pada bulan Agustus sampai dengan September 2021. Penangkapan jenis Krustasea di perairan Aceh Jaya dilakukan oleh nelayan setempat. Pengambilan sampel menggunakan alat tangkap jaring insang (Gill net). Hasil penelitian menunjukkan komposisi jenis hasil tangkapan krustasea berjumlah 1.533 individu. yang termasuk ke dalam 25 spesies, 1 kelas, 1 ordo dan 10 famili.

Abstract

Mangroves are biological natural resources that have the potential to provide benefits for human life and aquatic biota organisms. Mangrove ecosystems have ecological and economic functions in coastal areas. The Gampong Lamtutui area has an important role because it is a provider of natural resources and environmental services with great potential in terms of ecology, economy and tourism. So far, the activities that occur in the mangrove ecosystem area in Lamtutui have an unfavorable impact on the mangrove vegetation in that location, due to the large number of uses of the mangrove area for vannamei shrimp pond areas, so that the structure of mangrove vegetation at various growth levels changes. The purpose of this service is to raise awareness and motivation for the coastal communities of Gampong Lamtutui to replant mangroves as a form of concern for the preservation of coastal ecosystems. This service activity is carried out for two days, from October 30, 2021 to October 31, 2021. The location of this service is in Gampong Lamtutui, Peukan Bada District, Aceh Besar Regency. The method of activity used in this activity is counseling and mentoring mangrove planting. The results of this service activity are the planting of 1,000 stems of Rhizophora sonneratia mangrove tree seeds in Gampong Lamtutui, as well as the establishment of cooperation with a group of local fishermen for monitoring the mangrove trees that have been planted.
