Abstract

Analysis of BOD and COD has been done at estuary of Cut River in Alue Naga Village from March to April 2017. The purpose of this research was to analysis the water quality in Krueng Cut estuarial area, which is compared to the Government Regulation No. 82/2001. The method used in this research is field survey by employing purposive sampling method and laboratory analysis to the samples obtained in the field.The BOD, COD, DO, nitrate, nitrate was tested at Laboratory of Chemistry, Faculty of Marine and Fishery of Syiah Kuala University by applyingspectrophotometric method using Filterfotometer PF-11. The results showed that the highest concentration of BOD and COD was at station 3 where the mixing region occurred because the freshwater from river uphill meets with salt-water from the ocean, and the lowest BOD and COD concentration was at station 7 whichis the mouth of the estuary. The results obtained that water quality in Krueng Cut waters based on Government Regulation of water quality no. 82/2001 on the water quality categorized as a class III water quality, which is the water that can be used only for the function of fishery cultivation.Analisa BOD dan COD telah dilakukan di perairan Krueng Cut Desa Alue Naga yang dilakukan pada bulan Maret sampai dengan April 2017. Tujuan dari penelitian ini adalah untuk mengetahui kualitas air di perairan Krueng Cut Desa Alue Nagayang dibandingkan dengan Peraturan Pemerintah (PP) nomor 82 Tahun 2001.Metoda yang dilakukan dalam penelitian ini adalah survey lapangan dengan metode purposive sampling dan analisa laboratorium terhadap sampel yang diperoleh di lapangan untuk uji BOD, COD, DO, nitrat, nitrit di Laboratorium Kimia Laut Fakultas Kelautan dan Perikanan Universitas Syiah Kualadengan metoda Spektofotometri Filterfotometer PF-11. Hasil penelitian menunjukkan bahwa konsentrasi BOD dan COD tertinggi berada pada stasiun 3 yaitu daerah sirkulasi arus (pertemuan antara arus air tawar dan air asin), dan konsentrasi BOD dan COD terendah berada di stasiun 7 yang merupakan daerah mulut estuari. Hasil penelitian diperoleh bahwa kualitas air di perairan Krueng Cut berdasarkanPeraturan Pemerintah No. 82 Tahun 2001 tentang kualitas air baku mutu dikatagorikan sebagai kualitas air kelas III yaitu air yang dapat digunakan hanya untuk fungsi pembudidayaan perikanan.

Abstract

The study proposed to evaluate growth performance of post-larvae of jelawat (Leptobarbus hoevenii) fed on varius combination of natural food and artificial feed. Completely randomized design was assigned in this study. The treatments were various combinations of life feed of Moina sp. and artificial diet at a respective rates of 100:0%, 75:25%, 50:50%, 25:75% and 0:100%. The larvae of 20 days in age and 0.0287±0.0012 g  in weight was randomly stocked in 15 buckets at a stocking rate of five larvae per liter or 50 larvae  per bucket and fed on test diet at a feeding rate of 5% per body weight per day, divided in feeding frequency of five times for 45 days of rearing period. The results indicated that 20 days old of larvae jelawat fed on combinations of Moina sp. and artificial diet at 50:50 performed higher survival as well as growth.Tujuan penelitian adalah untuk mengevaluasi performa pertumbuhan post larvae jelawat (Leptobarbus hoevenii) pada berbagai kombinasi pakan alami dan pakan buatan. Rancangan Acak Lengkap digunakan dalam penelitian ini. Perlakuannya adalah berbagai kombinasi pakan alami Moina sp. dan pakan buatan, masing-masing yaitu 100:0%, 75:25%, 50:50%, 25:75% and 0:100%. Larva ikan jelawat umur 20 hari dengan bobot rata-rata 0,0287±0,0012 g ditebar secara acak ke dalam 15 buah ember dengan kepadatan 5 ekor per liter atau 50 ekor per wadah dan diberi pakan uji sebanyak 5% dari bobot tubuh per hari yang dibagi dalam lima kali pemberian selama 45 hari masa pemeliharaan. Hasil penelitian menunjukkan bahwa larva ikan jelawat umur 20 hari mempunyai kelangsungan hidup dan pertumbuhan lebih baik dengan pemberian kombinasi pakan alami Moina sp.. dan pakan buatan sebesar 50% : 50%.

Abstract

The aims of the study were to examine the exact percentage of prebiotics in sinbiotics, administered through feed, so as to enhance nonspecific immune responses in white shrimp. The sweet potato extract was used as prebiotic, combined with local isolated Bacillus sp. D2.2 as a probiotic applied simultaneously as a synbiotic. The feed was treated with 0% sinbiotic treatment (treatment A / control), 0% prebiotic and 6% probiotics (B treatment), 2% prebiotic and 6% probiotics (treatment C), 4% prebiotics and 6% probiotics (treatment D). Examination of nonspecific immune responses to shrimp included total hemocyte count (THC), phagocytosis activity (AP), phagocytosis index (IP), phenoloxidase activity (PO), and superoxide dismutase activity (SOD). Observation of the non-specific immune response of vaname shrimp after treatment showed that treatment C was the best prebiotic  to increase non-specific immune response in vaname shrimp.Penelitian ini bertujuan untuk mempelajari persentase prebiotik yang tepat dalam sinbiotik, yang diberikan melalui pakan, sehingga dapat meningkatkan respon imun nonspesifik pada udang vaname. Dalam penelitian ini digunakan ekstrak tepung ubi jalar sebagai prebiotik, dikombinasikan dengan isolat lokal Bacillus sp. D2.2 sebagai probiotik yang diaplikasikan secara bersamaan sebagai sinbiotik. Pakan yang diberikan adalah pakan dengan perlakuan 0% sinbiotik (perlakuan A/kontrol), 0% prebiotik dan 6% probiotik (perlakuan B), 2% prebiotik dan 6% probiotik (perlakuan C), 4% prebiotik dan 6% probiotik (perlakuan D). Pemeriksaan respon imun nonspesifik pada udang meliputi total hemocyte count (THC), aktivitas fagositosis (AF), indeks fagositosis (IF), aktivitas phenoloxidase (PO), dan aktivitas superoxide dismutase (SOD). Pengamatan pada respon imun non spesifik udang vaname setelah diberi perlakuan menunjukan bahwa perlakuan C merupakan persentase prebiotik terbaik untuk meningkatkan respon imun non spesifik pada udang vaname.
