Abstract

Tilapia is one of the commodities favored by the community and is widely cultivated in Indonesia. At this time, the development of tilapia cultivation has entered the location of marine and brackish waters, known as saline tilapia. The increase in tilapia cultivation has increased feed production, so the price of raw materials, especially fish oil, has increased. The source of crude fat that is usually used in feed formulations is fish oil, but the availability of fish oil is limited, so the price is increasing. One of the alternatives that can replace fish oil is maggot oil. Maggot contains 42-48% lipids. The purpose of this study is to find the effect of giving maggot oil on the growth and survival of saline tilapia. The method used was experimental, with a completely randomized design (CRD) consisting of 4 treatments and three replications. The treatments tested were treatment A (control), B (1.5 ml of maggot oil), C (2 ml of maggot oil), D (2.5 ml of maggot oil)) on 100 grams of feed. The saline tilapia used was 1.4-1.9 grams/head. The fish were reared for 30 days in 15-liter volume containers, ten fish density, and were fed three times a day. The results showed that fish oil substitution using maggot oil (H. illucens) significantly affected FUE, SGR, absolute weight, FCR, and SR of saline tilapia. The best dose of maggot oil was found in treatment B with a dose of 1.5 ml/100 grams of feed capable of producing FUE (88.783.80%), SGR (7.980.23%/day), absolute weight (41 .17 4.57gram), FCR (1.130.05), and SR (1000.00%).Keywords:BSFBrackish waterSGRProductionWeight

Abstract

High fish stock density causes a decrease in water quality due to increased organic waste in water media and this can be overcame using biofloc technology. The bacterial consortium in the biofloc system breaks the organic compound into nutrients for phytoplankton growth. This research aims to determine phytoplankton abundance in biofloc ponds with different catfish stocking densities. Furthermore, a completely randomized design (CRD) was used, with four treatments and three replications. The treatments involved 1,000, 1,500, 2,000, and 2,500 catfish per m3, respectively, with a weight of ± 1-3 grams. Also, the fish was fed 3% of its body weight and reared for 40 days in a tarpaulin pond, with a water volume of ± 1,974 L. The AMOVA test was used to analyze the data and 10 phytoplankton genera were observed. However, the phytoplankton abundances showed no statistical significance among the treatments. The results showed that the first treatment had the most abundant phytoplankton, with an average number of 13,394 cell/L.Keywords:AbundanceBioflocCatfishDensityPhytoplankton

Abstract

Microplastics are particles that have a size of 5 mm, where its existence might be able to contaminate the biota in the aquatic environment. This research was conducted in the coastal waters of Bengkalis Island in December 2020 with the aim to determine the types and analyze its abundance of microplastics in each area with different sources of anthropogenic input in the north and south Bengkalis Island. Sampling of sea water for microplastic analysis was done using plankton net (diameter 30 cm and mesh size 30 μm) from six sampling stations. Thirty six individual samples of Duri (Arius maculatus), Lomek (Harpodon nehereus), and Biang (Setipinna breviceps) fish were obtained with the help of local fishermen in each sampling location. The results showed that the types of microplastics found in seawater samples are fiber and film with average abundance ranges between 9.58 particles/m3 - 40.42 particles/m3. The highest abundance was found in station 6 (60.83 ± 8.61 particles/m3 and 20.00 ± 8.94 particles/m3) for fiber and film, whilst the lowest abundance was found in station 3 (12.50 ± 5.24 particles/m3 and 6.67 ± 6.06 particles/m3) for fiber and film, respectively. The average abundance of microplastics found in the digestive tract of fish was 62.96 particles/ind. which consisted of fiber, film and fragment. The highest microplastic abundance was found in Duri fish (72.22 particles/ind.), whilst the lowest was found in Lomek fish (55.56 particles/ind.). Although the abundance of microplastic in coastal waters of north Bengkalis were higher than that in the south of Bengkalis Island, statistically they were significantly different. This was presumably due to differences in oceanographic influences such as current and waves between the two water masses as well as anthropogenic activities in both areas that can affect the spread and distribution of microplastics.Keywords: plastic waste, Bengkalis waters, demersal fish, pelagic fishABSTRAKMikroplastik adalah partikel yang memiliki ukuran 5 mm, di mana keberadaannya dapat mencemari biota di lingkungan akuatik. Penelitian ini dilakukan di perairan pantai Pulau Bengkalis pada Desember 2020 dengan tujuan untuk menentukan jenis dan menganalisis kelimpahan mikroplastik di setiap wilayah dengan berbagai sumber input antropogenik bagian utara dan selatan Pulau Bengkalis. Pengambilan sampel air laut untuk analisis mikroplastik dilakukan menggunakan plankton net (diameter 30 cm dan ukuran jala 30 μm) dari enam stasiun pengambilan sampel. Tiga puluh enam sampel individu ikan Duri (Arius maculatus), Lomek (Harpodon nehereus), dan Biang (Setipinna breviceps) diperoleh dengan bantuan nelayan lokal di setiap lokasi pengambilan sampel. Hasil penelitian menunjukkan bahwa jenis mikroplastik yang ditemukan dalam sampel air laut adalah fiber dan film dengan kisaran kelimpahan rata-rata antara 9,58 partikel/m3 - 40,42 partikel / m3. Kelimpahan tertinggi ditemukan di stasiun 6 (60,83 ± 8,61 partikel / m3 dan 20,00 ± 8,94 partikel / m3) untuk fiber dan film, sedangkan kelimpahan terendah ditemukan di stasiun 3 (12,50 ± 5,24 partikel / m3 dan 6,67 ± 6,06 partikel / m3) untuk fiber dan film. Kelimpahan rata-rata mikroplastik yang ditemukan dalam saluran pencernaan ikan adalah 62,96 partikel / ind. yang terdiri dari fiber, film dan fragmen. Kelimpahan mikroplastik tertinggi ditemukan pada ikan Duri (72,22 partikel / ind.), sedangkan yang terendah ditemukan pada ikan Lomek (55,56 partikel / ind.). Meskipun kelimpahan mikroplastik di perairan pantai Bengkalis utara lebih tinggi daripada di selatan Pulau Bengkalis, secara statistik mereka berbeda nyata. Ini mungkin karena perbedaan dalam pengaruh oseanografi seperti arus dan gelombang antara dua massa air serta aktivitas antropogenik di kedua daerah yang dapat mempengaruhi penyebaran dan distribusi plastik mikro.Kata kunci: sampah plastik, perairan Bengkalis, ikan demersal, ikan pelagis

Abstract

The marine environment is a rich sources of natural bioactive compounds which are not used optimally. It has been established that marine organisms contain a unique physicochemical characteristic that is very valuable to be applied for food industry and pharmaceutical. Recently, numerous study have been shown that compounds extracted from marine organisms possess various biological activities, including anticoagulant, anticancer and hypocholesterolemic. Moreover, fish oil and marine bacteria have been claimed as a source of omega-3 while crustaceans and seaweeds contained carotenoids and phenolic compounds. Based on a variety of biological activities of marine organisms, this review focuses on the potential use of marine-derived compounds as functional food ingredients and nutraceutical including some consideration of barriers for their application.Laut menyimpan sumber bahan fungsional yang relatif belum dimanfaatkan secara optimal. Karakteristik fisikokimianya yang kompleks dan tidak ditemukan pada biota terrestrial,   menjadikan bahan fungsional laut potensial untuk diaplikasikan dalam berbagai aspek seperti pengolahan makanan, pengawetan, fortifikasi dan industri farmasi. Selain itu, banyak penelitian menunjukkan bahwa senyawa yang diekstrak dari biota laut memiliki aktivitas biologis yang beragam. Sebagai contoh, peptida yang diisolasi dari hidrolisat protein ikan serta fucans, galaktan dan alginat dari alga telah terbukti memiliki aktifitas antikoagulan, antikanker dan hipokolesterolemik. Selain itu, minyak ikan dan bakteri laut merupakan sumber yang asam lemak omega-3, sedangkan krustasea dan rumput laut mengandung senyawa antioksidan seperti karotenoid dan senyawa fenolik. Berdasarkan beragam aktifitas bioaktif yang terkandung pada bahan laut, review ini berfokus pada potensi senyawa laut sebagai bahan pangan fungsional dan nutrasetikal sekaligus tantangan dalam pemanfaatannya.

Abstract

The objectives of present study were to determine the distribution of sediment associated with shoreline changes and to analyze the beach dynamics in Rening Beach. Sediment samples were taken from seventeen sampling points spread along the beach, and then followed by the lab test using granulometri method to determine the characteristics of sediment. Shoreline change was analyzed using analysis of satellite imagery in 2011, 2014 and 2016, while the sediment transport were analyzed using Hjulstrom graph. Then, Rening Beach dynamics can be analyzed. Sediment test results showed that sediment type in Rening Beach was dominated by sand with diameter of between 0.25-5 mm. The ocean currents movement was dominantly to the west. The results of shoreline change analysis between the years 2011-2016, and Hjulstrom graph analysis showed the same pattern that Rening Beach was eroded. The Rening Beach was high dynamics with subjected to beach erosion in the form of littoral drift due to longshore currents.Penelitian ini bertujuan untuk mengetahui perubahan garis pantai, transpor sedimen dan dinamika pantai di Pantai Rening. Pengambilan data arus dan sampel sedimen diambil dari tujuh belas titik pengambilan sampel yang tersebar merata di sepanjang perairan Pantai Rening. Sampel sedimen kemudian diujikan di laboratorium menggunakan metode granulometri untuk mengetahui karakteristik sedimen. Perubahan garis pantai dianalisa menggunakan analisis peta citra satelit tahun 2011, 2014 dan 2016, sedangkan pola transpor sedimen dianalisa menggunakan grafik Hjulstrom. Dari hasil analisa perubahan garis pantai dan transpor sedimen, dapat dianalisa dinamika Pantai Rening. Hasil uji sedimen menunjukkan bahwa jenis sedimen didominasi oleh pasir sedang dengan diameter antara 0.25-5 mm. Pergerakan arus dominan mengarah ke arah barat. Hasil analisis perubahan garis pantai antara tahun 2011-2016, dan analisa grafik Hjulstrom menunjukkan pola yang sama bahwa pada Pantai Rening mengalami erosi dan mundurnya garis pantai. Dinamika Pantai Rening cukup tinggi dengan kecenderungan terjadi erosi pantai berupa littoral drift akibat arus sejajar pantai.
