POTENSI SERBUK DAUN PEPAYA UNTUK MENINGKATKAN EFISIENSI PEMANFAATAN PAKAN, RASIO EFISIENSI PROTEIN DAN LAJU PERTUMBUHAN RELATIF PADA BUDIDAYA IKAN NILA (Oreochromis niloticus)
Abstract: Tilapia is a fish
that has high economic value and is an important commodity in the business world
of freshwater fish. Some of the things that support the importance of
commodities tilapia, among others, have a relatively high resistance to
disease, have a wide tolerance to environmental conditions, has the ability to
grow well and can thrive well in intensive farming systems. Feeding efficiency
can reduce production costs, but still has the required nutritional value of
fish is an alternative that should be pursued. Several methods are used to
improve feed efficiency, including optimizing digestion and absorption of food
and increase the efficiency of the protein with the addition of digestive
enzymes. There are two types of digestive enzymes in the enzyme or enzymes
endogeneous eksogeneous to help accelerate the process of digestion and
hydrolysis. One eksogeneous enzyme is an enzyme papain. The purpose of this study
is to analyze the improvement of the efficiency of feed utilization, increasing
and enhancing the protein efficiency ratio relative to the growth rate of
tilapia due to the addition of papaya leaf powder. The method used is a method
laboratory experiments. While the research design used in this research is
completely randomized design (CRD), with all the factors conditioning the same
and homogeneous, except for the treatment factor. Treatments consisted of 3
treatments and repeated each 6 replications, namely: A1: treatment of feeding
with powdered papaya leaves 2%, A2: treatment of feeding with powdered papaya
leaves 3%, A3: treatment of feeding with powdered leaves of papaya 4% and C: feeding
without addition of the enzyme papain (control). The main parameters in this
study is the efficiency of feed utilization, protein efficiency ratio of the
feed rate relative pertumhuhan on tilapia, fish protein in meat and fish meat
thickness. Fish feed without the addition of the enzyme papain proximate tested.
Once given the addition of papaya leaf powder, tested proximate feed back. The
amount of feed intake was calculated by weighing the amount of feed that has
been consumed during treatment (30 days). The research result analysis showed
that papaya leaf powder addition of as much as 2% can improve the efficiency of
feed utilization in tilapia fish farming amounted to 36.65%, can increase the protein
efficiency ratio amounted to 0.55%, could increase the growth rate relative to
the cultivation of tilapia by 2,725% , can increase the protein content in the
flesh of tilapia by 17.98%. As for the treatment of papaya leaf powder addition
of as much as 3% can increase the thickness of the flesh of tilapia by 38.09%.
