APLIKASI TEPUNG DAUN TURI HASIL FERMENTASI DALAM PAKAN BUATAN TERHADAP PERTUMBUHAN BENIH IKAN NILA SRIKANDI (OREOCHROMIS AUREUS X NILOTICUS)
ABSTRACT: The aim of this research
is to determine the effect of fermented flour turi leaves in artificial feed on
the growth of Srikandi niloticus fish seed (Oreochromis aureus x niloticus).
This research was conducted on Desember 5, 2016 to Januari 5, 2017 in the
Laboratory of Brackish Water, Faculty of Fisheries, Pekalongan University. The
research method used experimental methods with Complete Random Design (CRD),
consisting of 4 treatments and 4 replications. The feed used is artificial
feed, whcih added turi leaves fermented flour with different precentages 0 %, 5
%, 10 %, and 15 %. The fish used are Srikandi niloticus fish seed, sized 5-7
cm, stocked in the aquarium, with density of 1 fish/L. The parameters observed
were the growing biomass, the survival rate (SR), and the quality of water as
supporting data. The results of this research showed that the use of fermented
flour turi leaves in artificial feed, affect the growth of Srikandi niloticus
fish seed (F count (80,53)> F table (5,96)). The use of fermented flour turi
leaves gave the highest yield to the biomass growth rate of Srikandi niloticus
fish seed on a treatment equal to 7,33 grams. The results of polynomials
orthogonal analysis produced the forms quadratc equation Y = 3,28 + 0,54 X –
0,02 X2 (R2 = 0,78), where X is the percentage of turi leaves fermented flour
addition in artificial feed and Y is the growth of Srikandi niloticus fish seed
biomass. Based on those equation, the result obtained maximum value X = 12,43 %
of the total weight percentage of the feed additions, and maxmimum value Y =
6,64 grams. The survival rate of Srikandi niloticus fish seed during the
research reached 100 %. The water quality research is feasible for media
maintenance of Srikandi niloticus fish, that is temperature 26 – 29o C, pH 6.7
– 7.8, DO 6 mg/l.
