Keanekaragaman Jenis Ikan Yang Tertangkap Secara Temporal Pada Perairan Pantai Kota Merauke

This study aims to determine the temporal diversity of fish, namely based on the moon phase and tides, the relationship between the moon phase and tides in the coastal waters of Merauke City. This research was conducted in June-August 2020. Determination of sampling points at the research location using purposive random sampling method. Data analysis used was fish species composition, Shannon-Wienner diversity index (H'), uniformity index (E), and dominance index (C). The total fish catch during the study time was 1,151 fish, which were divided into 19 fish species. The thick-lipped catfish (Cinetodus crassilabris) was the most caught species and spread in each station with a total of 298 fish. Based on the tidal period, the highest diversity of 2.23 was obtained during the high tide period and the lowest diversity of 1.89 at low tide. Both were found at Station I and fell into the medium category. The value of the diversity index based on the moon phase, the highest value during the full moon phase with a value of 2.12 and the lowest of 1.78 was found in the last quarter phase, both found at Station I. The uniformity value during high and low tide and based on the moon phase at both stations has a high uniformity category. The highest fish dominance was at low tide at station II with a value of 0.20 while the lowest value was at high tide at station I with a value of 0.14.Penelitian ini bertujuan untuk mengetahui keragaman ikan secara temporal yaitu berdasarkan fase bulan dan pasang surut, keterkaitan fase bulan dan pasang surut di perairan pantai Kota Merauke.

Analisis Kesesuaian Lahan untuk Padi di Distrik Semangga, Kabupaten Merauke

This study aimed to determine the land suitability for paddy plantation in Semangga subdistrict, Merauke Regency, Papua Province and to identify any treatments that needs to be taken to promote the land suitability classes. The information on land suitability is important to determine the treatment required in land preparation in order to achieve optimal production. Survey was conducted to collect necessary data which includes climate data, nutrient content (N, P, K available), Cation Exchange Capacity (CEC), pH, and toxicity. These data are interpolated within the area of Semangga subdistrict and classified based on the criteria developed by Indonesian Soil Research Institute - Ministry of Agriculture and FAO. Overlay analysis is performed in order to determine land suitability classes and the dominant limiting factor. Criteria for determining the suitability classes was taken from the lowest class of land unit. The results showed that the area of 1% (360.09 hectare) is classified as class of S2wfn, 55.8% (19,495.83 hectare) as class of S3n, 7% (2,431.83 hectare) as class of S3np, 35.3% (12,349.74 hectare) as class N1n, and 0.9% (306.6 hectare) as class of N2f. The finding of land suitability classes and its dominant inhibitory factor can be used then to determine the proper land treatment planning such as fertilization, liming, and drainage system design

Exploring the vertebrate fauna of the Bird’s Head Peninsula (Indonesia, West Papua) through DNA barcodes

Biodiversity knowledge is widely heterogeneous across the Earth's biomes. Some areas, due to their remoteness and difficult access, present large taxonomic knowledge gaps. Mostly located in the tropics, these areas have frequently experienced a fast development of anthropogenic activities during the last decades and are therefore of high conservation concerns. The biodiversity hotspots of Southeast Asia exemplify the stakes faced by tropical countries. While the hotspots of Sundaland (Java, Sumatra, Borneo) and Wallacea (Sulawesi, Moluccas) have long attracted the attention of biologists and conservationists alike, extensive parts of the Sahul area, in particular the island of New Guinea, have been much less explored biologically. Here, we describe the results of a DNA-based inventory of aquatic and terrestrial vertebratecommunities, which was the objective of a multidisciplinary expedition to the Bird's Head Peninsula (West Papua, Indonesia) conducted between 17 October and 20 November 2014. This expedition resulted in the assembly of 1005 vertebrate DNA barcodes. Based on the use of multiple species-delimitation methods (GMYC, PTP, RESL, ABGD), 264 molecular operational taxonomic units (MOTUs) were delineated, among which 75 were unidentified and an additional 48 were considered cryptic. This study suggests that the diversity of vertebrates of the Bird's Head is severely underestimated and considerations on the evolutionary origin and taxonomic knowledge of these biotas are discussed.Fieldwork and laboratory activities were supported by the Lengguru 2014 Project (www.lengguru.org), conducted by the French National Research Institute for Sustainable Development (IRD), the Indonesian Institute of Sciences (LIPI) with the Research Centre for Biology (RCB), and the Politeknik KP Sorong, with the help of the Institut Français in Indonesia (IFI) and the French embassy in Jakarta, with corporate sponsorship from COLAS SA Company (Environment Department), Total Foundation, ABS, Wasco, Veolia Eau, SDV-Bolloré,Peer reviewe

Pendugaan stok ikan tomgkol di Selat Makassar Sulawesi Selatan

Ikan tongkol termasuk dalam golongan ikan tuna kecil, dan selalu bergerombol. Jenis ikan tongkol yang ada di Selat Makassar Sulawesi Selatan adalah Euthynnus affinis, Auxis thazard, dan Auxis rochei. Data produksi tahun 1999-2007 Dinas Kelautan dan Perikanan Provinsi Sulawesi Selatan  menunjukkan bahwa terjadi peningkatan produksi dan jumlah nelayan untuk melakukan penangkapan ikan tongkol.  Permintaan ikan yang meningkat tentu berpengaruh positif bagi peningkatan pendapatan nelayan, namun perlu disadari bahwa peningkatan permintaan sumberdaya tersebut selalu diikuti tekanan untuk melakukan eksploitasi semakin intensif. Tujuan penulisan adalah untuk mengetahui nilai lestari-Maksimum Sustainable Yield (MSY) dan Effort Optimal (Fopt.) ikan tongkol di perairan Selat Makassar Sulawesi Selatan serta mengetahui apakah telah terjadi over fishing atau belum dalam pemanfaatan ikan tongkol. Pengumpulan data dilakukan pada bulan Mei 2010 bertempat di Dinas Kelautan dan Perikanan Provinsi Sulawesi Selatan. Penelitian ini dilaksanakan dengan cara menganalisis data sekunder tahun 1999 sampai 2007 yang diperoleh dari Dinas Kelautan dan Perikanan Provinsi Sulawesi Selatan dengan model Schaefer dan Fox. Dari hasil penelitian disimpulkan bahwa : 1) nilai lestari (MSY) ikan tongkol di Selat Makassar Sulawesi Selatan adalah 4.069,75 ton per tahun dengan penangkapan optimum (Fopt.) 1.666.666,67 trip per tahun. 2) Keberadaan populasi ikan Tongkol  di perairan Selat Makassar Sulawesi Selatan telah mengalami over fishing, dimana hasil penangkapan pada tahun 2007 sebesar 6.139.6 ton telah melewati nilai lestari (MSY) ikan tongkol sebesar 4.069,75 ton per tahun

Keanekaragaman Jenis Ikan Di Perairan Rawa Dogamit Taman Nasional Wasur Merauke

Dogamit Swamp is one of the swamps in the Merauke Wasur National Park, which stores an abundant diversity of fish and biota. This study aims to examine the diversity of fish species in the waters of Rawa Dogamit. The research was conducted from July to August. The method of data collection was by determining 3 locations of observation stations, at each station an identification of all species and their environmental factors was then linked to the Diversity index, Abundance Index, Evenness Index, and Dominance. The results obtained from the study are that there are 15 species of fish, which have the highest abundance of Betik (Anabas testudineus) by 35.74% and the lowest is the Moon Fish (Megalops cyprinoides) by 0.05%. Measurement of the Diversity index is categorized as moderate, whereas for the Evenness index is categorized high at stations I and II, while station III is categorized as moderate. For the measurement of the Dominance Index, it is categorized as low or not dominant. It was concluded that there was a significant relationship between the diversity, evenness and dominance index with environmental parameters both for the survival of fish in Rawa Dogamit waters.Key Words: Diversity; Fish; Dogamit Swam
