Resirculating Aquaculture System (RAS) Technology Applications in Indonesia : A Review
Get PDFIncreasing aquaculture production will increase land use and environmental pollution, especially water quality for cultivation. Resirculating Aquaculture System is a solution in sustainable cultivation that can produce continuous production by minimizing its impact on the environment. The working principles of RAS include the process of solid waste disposal, biofiltration, degassing / CO¬2 stripping, aeration, and disinfection. Based on literature studies, the use of RAS technology in Indonesia has been carried out both on a small scale such as aquaponics and on a large scale in several Balai Sulawesi, Yogyakarta and Aceh to the application of integrated technology in RAS systems such as microbubble and Immuno-Probiocirculation System (SI-PBR). RAS implementation management includes the selection of fish species, selection of feed, the cultivation system used, the filters used and the shape of the cultivation pond. Although the RAS system involves high capital investment and risk factors, this can be balanced with the production of superior quality fish / shrimp without disruption anywhere and anytime
STRATEGI PENGEMBANGAN USAHA PERIKANAN TUNA di SENDANG BIRU MALANG PASCA PANDEMI COVID-19
Get PDFPenelitian ini difokuskan pada topik pengembangan perikanan tuna pasca pandemi COVID-19 di Sendang Biru Malang. Perikanan tuna merupakan salah satu komoditas terbesar yang ada di Indonesia. Produksi ikan tuna yang telah didaratkan di Pelabuhan Perikanan Pondok Dadap Sendang Biru (PPP Pondok Dadap) merupakan salah satu produksi terbesar di Indonesia dan nomor 1 di Jawa Timur. Produksi penangkapan ikan tuna selalu mengalami peningkatan setiap tahunnya. Hal tersebut sangat berpengaruh terhadap pendapatan masyarakat di Sendang Biru yang sebagian diantaranya bekerja sebagai nelayan dan pedagang ikan. Selama masa pandemi COVID-19, pendapatan masyarakat dari hasil perikanan tuna cenderung menurun dikarenakan berkurangnya permintaan dari beberapa restoran, pabrik dan beberapa pasar yang ada di Jawa Timur. Pandemi COVID-19 menyebabkan sulitnya distribusi ikan, sehingga biaya distribusi menjadi mahal. Dalam mengoptimalkan usaha perikanan tuna yang berkelanjutan pasca pandemi, maka dibutuhkan strategi pengembangan usaha perikanan tuna dengan meninjau beberapa kekuatan, kelemahan, peluang dan ancaman yang ada pada usaha perikanan tuna di Sendang Biru Malang. Luaran dari penelitian ini adalah Strategi Pengembangan Usaha Perikanan Tuna di Sendang Biru Malang pasca pandemi COVID-19.

Comparison of Admiralty and Least Square Methods for Tidal Analysis in Mandangin Island, Sampang Regency, East Java
Get PDFThe existence of hydro-oceanographic information such as tides plays an essential role in supporting coastal areas' transportation. This study aims to compare the tidal analysis results in Mandangin Island, Sampang Regency, East Java using the Admiralty and Least Square methods. The data used in this study are tidal data for May and November 2020, which represent the dry and rainy seasons in Indonesia. Tide data are obtained from the Geospatial Information Agency (BIG) at one-hour intervals. From this research, it can be concluded that the tidal types generated from the Admiralty and Least Square methods in Mandangin Island, East Java, are mixed types with semidiurnal tendencies. The use of the Admiralty and Least Square methods results in the difference in the harmonic components' amplitude values. The M2 and O1 components have an enormous difference in May 2020, with amplitude values of 0.0003 and 0.0002, and the difference in the amplitude values of the harmonic components also occurred in November 2020. The M2 component has the most significant difference compareto other components, namely 0.0011. The components O1, P1, and MS4 in the same month result in a relatively small difference in amplitude values with values of 0.0002, 0.0002, and 0.0001. For further tidal research, data corrections should be considered, a nodal correction to produce more accurate observational data. This correction can use the T_Tide program with constants obtained from the analysis process
