Abstract

Groupers are one of the most important and commercial fishes; many of the species are classified as Life Reef Fish Trade (LRFT). The number of grouper species in these locations may be more diverse than at other sites. Identifying the species number of a grouper is essential for mapping reef fitness. However, morphological identification of groupers is relatively difficult. Molecular methods such as DNA barcoding could be an option and even serve as reliable validation. Therefore, this research was conducted to identify groupers belonging to the Serranidae family. The grouper samples were obtained from the fish market in Waisai, Raja Ampat, Indonesia. The DNA barcoding employed the COI genes to accurately identify groupers. The Qiagen DNeasy 96 tissue extraction kit was used to extract DNA, and Primer Fish F1/R1 was applied. The sequences were analysed using ClustalW in MEGA 7.0 and phylogenetic tree was generated using the NJ (Neighbour Joining) method. Eleven species of groupers belonging to five taxa were discovered in Waisai, Raja Ampat. Anyperodon, Cephalopholis, Epinephelus, Plectropomus, and Variola are the grouper genera. Epinephelus was the predominant genus within the serranidae family, with 51.4% of the total. The International Union for Conservation of Nature's (IUCN) Red List category puts the majority of grouper species in the 'Least Concerned' category. This study confirmed the effectiveness of DNA barcoding for species identification and the value of the COI gene for Grouper's phylogenetic research. The outcome offers information about fisheries resources, which should be helpful in managing fisheries in reef ecosystems.

Abstract

Mangroves are an ecosystem that has an important function for coastal areas, the existence of mangroves provides ecological, economic, and social functions. Therefore, mangrove ecosystem management must be carried out using an environmental sustainability approach and natural resource sustainability to avoid damage to the existence of the mangrove ecosystem. This research aims to analyze the status of sustainability of mangrove ecosystem management in the Mangrove Hijau Daun area, Daun Village, Sangkapura District, Bawan Island, Gresik Regency. This research was carried out from June to August 2023. The method used was RAPFISH (Rapid Appraisal for Fisheries) analysis with a Multidimensional Scaling (MDS) approach based on ecological, economic, social, and institutional dimensions. The results of the research show that the sustainability status of the mangrove ecosystem in the green leaf mangrove area of Bawean Island obtained a multidimensional index value of 72.56, including in the quite sustainable category, each dimension has an index value, namely the ecological dimension of 88.68, the economic dimension of 49.80. , the social dimension is 78.40, and the institutional dimension is 88.12. The economic dimension is a dimension whose management needs to be encouraged because it has an index value in the less sustainable category.

Abstract

Nowadays, there are still many high capacity generators have not yet protected completely from their internal ground faults. They still rely on differential and over current relays. It is seen that this relay will reduce their sensitivities when applied to generators with high impedance grounding systems. To overcome such problem, a combination protection scheme of the neutral overvoltage (59N) and neutral undervoltage third harmonics (27N3) is developed. This paper aims to design the protection scheme for high capacity generators. This paper demonstrates the designing of neutral grounding transformer (NGT) system, the relay settings and reviewing of their sensitivities. To clarify the concepts this study uses a generator 802 MVA, 22.8 kV as object. The results show that the protection scheme is very effective to protect 100% of generator stator with relays overlapping of 31.5%. It needs NGT transformer with capacity of only 28.33 kVA, 15000/240 V, and the secondary resistor of 0.38,117 kW. This paper can hopefully be used as one reference for protection system engineers to design or develop protection schemes in their fields especially whose generator has not equipped yet with such protection scheme.

Abstract

Lobster pasir (Panulirus homarus Linnaeus, 1758) merupakan jenis spiny lobster yang paling banyak dibudidayakan di Indonesia. Zooplankton menjadi mangsa penting dari spiny lobster dan diduga menentukan keberhasilan budidaya spiny lobster terutama pada fase puerulus dan juvenil awal. Tujuan penelitian ini adalah untuk mendata jenis, indeks keanekaragaman (H’), dan kelimpahan spesies zooplankton di Teluk Ekas pada fase bulan yang berbeda di kedalaman penempatan wadah pemeliharaan puerulus lobster. Sampel zooplankton diperoleh ketika fase bulan gelap dan terang pada bulan Juni-Juli 2021 dari tiga kedalaman penempatan puerulus (0,5 m, 1 m, 1,5 m). Karakteristik morfologi digunakan dalam identifikasi jenis zooplankton menggunakan beberapa buku identifikasi dan konfirmasi nama spesies di website World Register of Marine Species (https://www.marinespecies.org/). Total sebanyak 14 jenis zooplankton diperoleh yang terbagi ke dalam enam kelas yakni appendicularia (1), bivalvia (1), copepoda (3), malacostraca (2), oligotrichea (6), polychaeta (1). Copepoda  merupakan kelompok yang ditemukan paling melimpah dan berpotensi sebagai pakan alamiah dalam budidaya benih spiny lobster. Fase bulan gelap memiliki taksa yang lebih tinggi, dengan keanekaragaman dan kelimpahan zooplankton lebih tinggi di bulan terang pada tiap kedalaman laut pengambilan sampel.

Abstract

Ikan kembung lelaki (Rastrelliger kanagurta) memiliki nilai ekonomis penting bagi nelayan. Tekanan eksploitasi yang tinggi memengaruhi keberadaan stok dan keseimbangan ikan tersebut di alam. Efektivitas pengelolaan perikanan perlu dilakukan, diantaranya melalui kajian struktur stok. Kajian struktur stok dengan analisis genetik dapat menunjukkan status genetik stok dan aliran gen pada setiap stok dalam suatu populasi. Informasi ini dapat digunakan sebagai dasar pengelolaan sumberdaya perikanan. Penelitian ini bertujuan untuk menganalisis keragaman dan struktur genetik, serta struktur stok ikan kembung lelaki di WPP-NRI 711, 572, dan 573 menggunakan pendekatan molekuler. Isolasi dan ekstraksi DNA menghasilkan 20 DNA total per-lokasi (enam lokasi), dan diamplifikasi dengan metode PCR. Terdapat 109 dari 120 sampel hasil PCR yang dilanjutkan ke tahap RFLP. Hasil dari proses pemotongan band tunggal oleh enzim restriksi (RFLP) diidentifikasi menggunakan program Popgene32. Enzim yang mampu menunjukkan polimorfisme yaitu AluI dan HaeIII. Stok ikan kembung lelaki di WPP-NRI 711, 572, dan 573 memiliki kedekatan secara genetik, sehingga mengindikasikan sebagai unit stok tunggal. Namun, jarak genetik yang visualisasikan dengan dendrogram menunjukkan stok membentuk dua clade yang terpisah. Dalam pengelolaannya lebih baik menjadi unit manajemen terpisah untuk kepentingan statistik.

Abstract

This study aims to assess the distribution of Cherax quadricarinatus based on depth and evaluate its invasiveness using a risk assessment in Lake Laut Tawar, Central Aceh. The study was conducted at five stations representing various lake activities: Station 1 (One-One), Station 2 (Bewang), Station 3 (Gegarang), Station 4 (Mendale), and Station 5 (Dedalu). The methodology involved direct observation in the field followed by laboratory analysis. The results showed that 284 individuals were caught, consisting of 138 females and 146 males, with carapace lengths ranging from 20 to 76 mm. No consistent distribution of male and female carapace lengths was observed across all stations. The abundance of Cherax quadricarinatus in Lake Laut Tawar was classified as very abundant (20%) at One-One and Bewang stations, both at a depth of 5 meters. In conclusion, Cherax quadricarinatus significantly dominates the lake ecosystem, as indicated by its relative abundance at different depths across the study sites. This species also shows a high potential for invasion in freshwater lakes, highlighting the need for effective management strategies.Keywords:Cherax quadricarinatusInvasive spesiesLake Laut Tawar, Aceh

Abstract

Besides overfishing, other factors that influence the decline in blue swimming crab (Portunus pelagicus) production are diseases caused by parasites. Poor environmental conditions could trigger parasite infestation on their host. This study aims to identify ectoparasites morphologically based on the research location and to analyze the prevalence of ectoparasites of the blue swimming crabs. Crab samples and data collection of aquatic environmental parameters were carried out at five locations in the northern part of Java Island, Indonesia: Pasuruan, Lamongan, Semarang, Cirebon, and Banten. The study was conducted from December 2021 to July 2023. Morphological identification of ectoparasites was carried out at the Biology Micro Laboratory I, Department of Aquatic Resources Management, IPB University. Interviews with fishermen were also conducted to ensure the crab catchment area around the research location. The number of blue swimming crabs obtained at each location varied, ranging from 25 to 35 individuals, consisting of large, medium, and small crabs. Based on the results of morphological identification, there were a total of five types of parasites found in all research locations, namely Allokepon sp., Chelonibia testudinaria, Octolasmis angulata, Octolasmis warwickii, and Octolasmis sp. The prevalence rate of crabs in each location was significantly different in five locations, namely Pasuruan, Lamongan, Semarang, Cirebon, and Banten, which were 80%, 74%, 80%, 12%, and 70%, respectively. The highest prevalence was in Pasuruan and Semarang. Factors affecting the prevalence rate of ectoparasites in blue swimming crabs included environmental quality such as temperature, salinity, pH, and dissolved oxygen (DO).

Abstract

Until this decade, Charybdis (Archias) padangensis was only from Padang, West Sumatra. It was reported first and the only one in 1952. We obtained several crab samples based on the by-catch from daily fishermen in several locations. Based on morphological identification, we obtained several Charybdis (Archias) padangensis individuals from two locations in Sumatra and one location in Java. The results of this research add to data on the distribution of the species, which was previously only known from the locality type.
