Abstract

Jawa Timur (Jatim) adalah salah satu propinsi yang memiliki potensi sumberdaya perikanan laut yang terdiri dari ikan pelagis dan ikan demersal. Wilayah pengelolaan perikanan laut di Jawa Timur bagian selatan memiliki potensi yang sangat besar karena berhadapan langsung dengan samudera Hindia dan memiliki potensi ikan khususnya kelompok pelagis besar seperti tuna (Thunnus sp) dan cakalang (Katsuwonus pelamis). Untuk mengetahui informasi tentang potensi dan tingkat pemanfaatan perikanan laut di Jatim perlu dianalisis data yang ada, sehingga dapat digunakan sebagai acuan dalam mengembangkan sektor perikanan laut kedepannya dengan memperhatikan kelestarian sumberdayanya. Tujuan penelitian adalah mengetahui potensi dan tingkat pemanfaatan ikan di wilayah Selatan Jatim. Metode penelitian yang digunakan adalah metode survey dengan analisa data menggunakan metode Maximum Sustainable Yield (MSY). MSY atau potensi lestari ikan adalah besarnya jumlah stok ikan tertinggi yang yang dapat ditangkap secara terus menerus dari suatu sumberdaya tanpa mempengaruhi kelestarian stok ikan tersebut. Dengan menggunakan metode surplus produksi, potensi lestari ikan (MSY) di wilayah Selatan Jatim periode 2009-2013 adalah sebesar 219.189,453 ton. Tingkat pemanfaatan ikan di perairan Selatan Jatim tahun 2009-2013 nilai rata-ratanya sebesar 49,48% yang berarti masih dibawah nilai jumlah tangkapan yang diperbolahkan (JTB sebesar 80%). Dari nilai tingkat pemanfaatan selama 5 (lima) tahun tersebut dapat dikatakan perairan Selatan Jatim masih dalam kondisi underfishing karena tingkat pemanfaatannya masih dibawah nilai JTB (kurang dari 80%). Rata-rata nilai upaya penangkapan sebesar 577.764 trip dengan upaya optimum sebesar 523.437 trip, maka dapat disimpulkan bahwa upaya optimum lebih rendah dibandingkan dengan nilai rata-rata upaya penangkapan selama 5 (lima) tahun.Kata Kunci: CPUE, MSY, potensi, tingkat pemanfaatan, upaya UTILIZATION POTENTIAL AND LEVEL OF FISH AS A BASIS FOR DEVELOPMENT SECTOR FISHERIES IN SOUTH EAST JAVAABSTRACTJawa Timur (East Java) is one of the provinces that have the potential of marine fishery resources consisting of pelagic and demersal fish. Marine fisheries management area in the southern part of East Java has a huge potential for dealing directly with the Indian Ocean and has the potential of large pelagic fish, especially groups such as tuna (Thunnus sp) and skipjack (Katsuwonus pelamis). To find out information about the potential and the level of utilization of marine fisheries in East Java needs to be analyzed existing data, so it can be used as a reference in developing the marine fisheries sector in the future by taking into account the preservation of resources. The research objective was to determine the potential and the utilization rate of the fish in the southern region of East Java. The method used is survey method with data analysis using the Maximum Sustainable Yield (MSY). MSY or the potential for sustainable fish is the large number of fish stocks highest that can be captured continuously from a resource without affecting the sustainability of fish stocks. By using surplus production, the potential for sustainable fish (MSY) in the southern region of East Java 2009-2013 period amounted to 219,189.453 tonnes. The utilization rate of the fish in the waters of South East Java in 2009-2013 the average score of 49.48%, which means it is still below the value of the catch volume be allowed (JTB by 80%). Of the value of the utilization rate for five (5) years could be said Southern waters Java is still in a state of underfishing because the level of utilization is still below the value JTB (less than 80%). The average value of 577 764 trips fishing effort with optimum effort amounted to 523 437 trips, it can be concluded that the optimum effort lower than the average value of fishing effort for five (5) years.Keywords: CPUE, MSY, the effort, the potential, the utilization rate

Abstract

Selat Bali sebagai penghubung Pulau Jawa-Bali semakin berkembang seiring peningkatan ekonomi dan wisata kedua pulau tersebut. Penelitian terhadap dinamika kondisi atmosfir kaitannya terhadap pergerakan arus laut di Selat Bali bagian Utara dengan memanfaatkan data arus permukaan laut yang dipisahkan menjadi komponen harmonik dan non-harmonik, citra satelit awan, curah hujan serta kondisi angin permukaan dan lapisan atas diharapkan dapat memberikan manfaat kepada pihak-pihak yang berkepentingan terkait perubahan kondisi arus permukaan mengacu pada perubahan kondisi fisis atmosfir. Hasil penelitian menunjukkan bahwa arus permukaan Selat Bali didominasi oleh arus harmonik pada arah meridional (Utara- Selatan) dengan nilai perbandingan rata-rata kecepatan terhadap arus non-harmonik (residu) sebesar 2.655. Angin lokal yang berhembus tidak berdampak langsung terhadap pergerakan arus akibat luas Selat Bali yang sempit sehingga stress angin yang ditimbulkan tidak cukup kuat untuk membangkitkan arus residu permukaan. Tendensi arah angin monsun dari Barat- Barat Laut pada puncak musim hujan juga memiliki hubungan yang sangat lemah terhadap arus residu permukaan yang ditimbulkan. Angin maksimum serta faktor cuaca lain berupa hujan dengan intensitas ringan hingga lebat disertai petir juga tidak berdampak langsung terhadap pergerakan arus residu di Selat Bali bagian Utara.

Abstract

Labuan Bajo waters are marine tourism location that need meteorological and wave height information. The purpose of this research is determining local and regional wind patterns also their connection to wave height characteristics. The prosedure of this research is processing wind data using WR Plot and ArcGIS, then correlation analysis between wind and wave height using SPSS. The results showed that the dominant land breeze blows from South with an average speed of 2.18 knots while the sea breeze blows from Southwest, West, Northwest to North with an average speed of 5.83 knots. Regional wind patterns are influenced by seasonal wind patterns. In the West Season tends blow from West and Northwest with an average speed of 2.49 knots, in the East Season tends to blow from East and Southeast with an average speed of 2.64 knots while in the Transition Season tends to blow from various directions. On a daily, the waves tend to be high at 07:00 with an average of 1.39 m while at 19:00 tend to be low with an average of 0.26 m. Seasonally the highest wave height occurs in the West Season with an average of 1.35 m and the lowest wave height occurs in Transition Season II with an average of 0.79 m. Regional winds and wave heights have a moderate to strong connection in the East Season (R = 0.438-0.639).

Abstract

Beralas Pasir is part of the Regional Marine Conservation Area (KKLD), which was established by the Bintan Regency Government with Bintan Regent Decree No. 261 / VIII / 2007. Water tourism activities undertaken by tourists on the island have had an impact on the condition of the coral reefs, as have other factors, such as bauxite, granite and land sand mining activities around the island. This research aims to determine changes in the coral reef habitat cover and the condition of the coral reefs around Beralas Pasir Island with a remote sensing function, using SPOT 4 imagery acquired on June 1, 2011 and SPOT 7 imagery from April 5, 2020. Data collection of environmental parameters related to the coral reefs was also made. The image processing used the Lyzenga algorithm to simplify the image classification process. The percentage of coral live cover around the island ranges from 26% -53%; this has experienced a significant change, from 67,560 hectares in 2011 to 38,338 hectares in 2018, a total decrease in the area of 29,222 hectares. Some of the natural factors found in the research which have caused damage to the reefs were Drupella snails, the abundance of Caulerpa racemosaalgae, and sea urchins. The majority of the coral reef types consist of Non-Acropora: Coral Massive, Coral, Coral Foliose, Coral Encrusting, Acropora: Acropora Tabulate, Acropora Encrusting, and Acropora Digitate
