Abstract

The research aimed to isolate probiotic bacteria from catfish intestine and assign the concentration of probiotic bacteria which effectively increase the activity of phagocytosis and total leukocytes of carp fingerlings. The fish was taken from Balai Pengembangan dan Pembinaan Pembudidayaan Ikan (BP3I) Tateli. Fish (average initial weight of 2.27 g) were acclimated for one week in 15 aquaria with a density of 25 fish/aquarium. One week after acclimatization, fish were fed with food added with probiotics with different concentrations, namely 1x106, 1x107, 1x108, 1x109 cfu/mL for four weeks. The dose of feed was 5% /body weight/day and feeding time was at 08.00 and 17.00. Data collected were phagocytosis and total leukocyte count. The results showed that supplementation of probiotic significantly increased phagocytic activity and total leukocytes (p<0.01). The best phagocytic activity and total leukocytes were achived in fish fed diet added with probiotics 1x108 cfu/mL. It can be concluded that supplementation of  probiotic onto feed can increase phagocytic activity and total leukocytes of carp.

Abstract

Macroalgae is one of the potential biological resources in Indonesian waters that has many important roles, from an ecological to an economic perspective. The aim of this research is to analyse the structure of macroalgae communities found in the waters of Kumeke Island, East Bolaang Mongondow Regency, Indonesia. The method used in this research is a survey with descriptive data analysis. Determining the sampling station point is carried out by purposive sampling, namely by selecting an area based on the presence of macroalgae. Macroalgae sampling used the line transect method with a quadratic sampling technique with a size of 1.5 x 1.5 m. The research results showed that the types of macroalgae found were 11 species, consisting of 3 species of Chlorophyta, 4 species of Phaeophyta, and 4 species of Rhodophyta. The density of macroalgae species is dominated by Rhodophyta (38%), Phaeophyta (31%), and Chlorophyta (30%). The total density of macroalgae is 9–46 ind/m². The diversity index ranges from 1.154 to 2.234 in the medium category, the uniformity index ranges from 0.481 to 0.932 in the high category, and the dominance index ranges from 0.114 to 0.338 in the low category.

Abstract

Ekstrak daun andong merah (Cordyline fruticose) mengandung senyawa bioaktif flavonoid, polifenol, dan tanin sebagai penunjang kesehatan usus serta pemanfaatan nutrisi pada ikan dalam memacu pertumbuhan secara optimal. Tujuan penelitian ini dilakukan untuk mengetahui potensi ekstrak daun andong merah sebagai promotor pertumbuhan ikan nila (Cordyline fruticosa). Ikan nila sebagai ikan uji dipelihara dalam wadah terkontrol untuk diberi pakan yang ditambah ekstrak andong merah selama 30 hari menggunakan metode Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dosis (0, 5, 10, 15, 20 mL esktrak/kg pakan). Parameter pertumbuhan yang diamati adalah pertumbuhan mutlak, laju pertumbuhan spesifik (SGR), efisiensi pakan, dan Feed Conversion Ratio (FCR). Data dianalisis melaluli ANOVA dan uji lanjut Duncan. Hasil penelitian menunjukkan dosis 10 mL kg/pakan pada perlakuan C menghasilkan kinerja terbaik dengan nilai rata-rata pertumbuhan mutlak 8,91 gram dan 3,14 gram pada pertumbuhan spesifik. Selain itu nilai rata-rata efisiensi pakan 96,46 dan FCR 1,06 merupakan hasil terbaik dari perlakuan C. Kesimpulan dari penelitian ini bahwa ekstrak andong merah dosis 10 mL/kg pakan berpotensi digunakan sebagai promotor pertumbuhan pada budidaya ikan nila, efisiensi pakan, serta menurunkan rasio konversi pakan.
