Abstract

Study about chlorophyll-a state in Teluk Pria Laot Sabang has been done in October 2016. The objective of this study was to analyze the chlorophyll-a concentration and phytoplankton abundance in Teluk Pria Laot Sabang. Samples were collected at a station located at 5,84653oN and 95,29001oE during 4 days (4, 6, 8, and 10th October 2016) which each day had 4 sampling times (07:00 am, 10:00 am, 01:00 pm, and 04:00 pm). Chlorophyll-a, phytoplankton, and nutrient analysis were conducted at chemistry laboratory of Teacher Training and Education Faculty, Syiah Kuala University, marine chemistry laboratory of Marine and Fisheries Faculty, Syiah Kuala University, and Unit of Environment Research and Development, Banda Aceh. The result showed that chlorophyll-a concentration ranged 0,02  – 1,7 µg/L withthe highest average (0,64 µg/L) was obtained at 01:00 pm. In addition,phytoplankton abundance was found ranged3539,4 ind/L – 8687,3 ind/L andthe highest average (6435,0 ind/L) appeared at 10:00 am. Nitrate and phosphate concentration which were above the minimum value of threshold revealed that this area was rich in nutrient availabilityto support the phytoplankton growth. Chlorophyll-a concentrations are likely influenced by light intensity with rich nutrient availability than phytoplankton abundance. According to chlorophyll-a concentration, Teluk Pria Laot Sabang is categorized as Oligothropic area.Penelitian tentang status klorofil-a di Teluk Pria Laot Sabang telah dilakukan pada Bulan Oktober 2016. Tujuan dari penelitian ini adalah untuk mengetahui konsentrasi klorofil-a dan kelimpahan fitoplankton di Teluk Pria Laot Sabang. Sampel dikumpulkan pada stasiun yang terletak pada koordinat 5,84653oLU dan 95,29001oBT selama 4 hari dengan 4 kali waktu pengambilan per hari (pukul 07.00, 10.00, 13.00, dan 16.00 WIB). Analisis klorofil-a, fitoplankton dan nutrien dilakukan di Laboratorium FKIP – kimia Unsyiah, Laboratorium Kimia Laut, FKP Unsyiah, Balai Penelitian dan Pengembangan Lingkungan (BPPL) Banda Aceh. Hasil penelitian menunjukkan bahwa konsentrasi klorofil-a berkisar 0,02– 1,7µg/Ldengan nilai rata – rata konsentrasi klorofil-a tertinggi 0,64µg/L didapatkan pada waktu pengambilan pukul 13:00 WIB. Kelimpahan fitoplankton yang diperoleh berkisar 3539,4 ind/L – 8687,3 ind/L dengan rata – rata tertinggi dengan nilai 6435,0 ind/L diperoleh pada pukul 10:00 WIB. Konsentrasi nitrat dan fosfat yang berada di atas ambang batas minimal menggambarkan bahwa daerah ini menyuplai nutrien yang cukup untuk pertumbuhan fitoplankton. Fluktuasi konsentrasi klorofil-a lebih cenderung mengikuti perubahan intensitas cahaya matahari dengan ketersediaan nutrien (nitrat dan fosfat) yang cukup. Berdasarkan konsentrasi klorofil-a yang diperoleh, Perairan Teluk Pria Laot Sabang dikategorikan sebagaidaerah oligotrofik.

Abstract

The cultivation of giant gourami is constrained by its high mortality due to low resistance to diseases. Resistance is an inherited character from the parental to their seeds. High resistance seeds can be selected using molecular marker, such as Major Histocompatibility complex (MHC) gene. Resistance character is assumed to be different among individual from different broodstocks and is suggested related to their genetic constituent.  This research aims to analyze the resistance of sowang gouramy seeds from different broodstocks and describe genetic character of seeds from different broodstocks. An explorative survey was perfomed. One hundred individuals were taken purposively from Balai Benih Ikan Sikamaju Ciamis West Java and hundred individuals were bought from fish farmer in Ciamis West Java. Sampling was performed in 2015 for the first seed group and in 2016 for the second seed group. Samples were subjected to Aeromonas hydrophila and Pseudomonas aeruginosa infection. The fragments of MHC gene were amplified using PCR technique from eight individual of first group and six individuals of second group. The resistance characteristic was analyzed using simple mathematics based on the number of living seeds compared total infected seeds and molecular characteristics was analyzed descriptively based on DNA band pattern. Different resistance to A. hydrophila was observed between seed groups from different broodstocks. The seeds group from the first broodstocks showed lower resistance level with the value of 29% than that from the second broodstocks with the resistance value reached of 100%. Both seed groups also showed resistance differences to P.aeruginosa, although  not as high as A.hydrophila infection. The differencies were also reflected in their MHC gene between seed groups from two different broodstocks. The amplication of MHC gene of the seeds from the first broodstacks resulted of 585 bp and 400 bp length fragments, while from those second broodstocks was only resulted of 400 bp frament. The differences on DNA band pattern between seed groups indicate a different molecular characteristics among seeds from different broodstocks.Usaha budidaya ikan gurami terhambat oleh tingginya mortalitas benih karena rendahnya resistensi terhadap penyakit. Resistensi merupakan sifat yang diwariskan dari tetua ke anakan. Benih yang resisten dapat diseleksimenggunakan marka molekuler seperti gen Major Histocompatibility complex (MHC). Sifat resisten diduga berbeda diantara benih yang beraasal dari induk berbeda dan diduga terkait dengan kompenen genetik yang dimiliki. Tujuan penelitian ini adalah untuk mengetahui sifat reisten dan karakter molekuler benih gurami sowang asal induk berbeda. Fragmen gen MHC diamplifikasimenggunakan teknik PCR. Sifat resistensi dianalisis menggunakan perhitungan matematika sederhana berdasarkan jumlah benih hidup dibagi jumlah total benih yang diinfeksi, sedangkan karakter molekuler dianalisis secara deskritif berdasakan pola pita yang dihasilkan. Kedua kelompok benih memiliki sifat resistensi berbeda terhadap Aeromonas hydrophila. Benih dari induk pertama memiliki sifat resistensi lebih rendah dengan nilai kelangsungan hidup sebesar 29% daripada kelompok benih dari induk kedua yang memiliki kelangsungan hidup mencapai 100%. Kedua kelompok benih juga memperlihatkan perbedaan sifat resisten terhadap P. aeruginosa, meskipun perbedaannya tidak sebesar terhadap A.hydrophila. Perbedaan tersebut juga tercermin pada gen MHC kedua kelompok benih. Pada kelompok benih pertama dihasilkan dua fragmen gen MHC dengan ukuran 585 pb dan 400 pb, sedangkan dari kelompok benih kedua hanya dihasilkan fragmen berukeuran 400 pb. Perbedaan pola pita diantara kedua kelompok benih tersebut merupakan idikasi adanya perbedaan karakter molekuler pada benih yang berasal dari dua induk berbeda

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.
