PENGARUH PEMBERIAN FERMENTASI KOTORAN AYAM ROTI AFKIR DAN AMPAS TAHU DALAM MEDIA KULTUR MASSAL TERHADAP PERTUMBUHAN DAN KANDUNGAN NUTRISI DAPHNIA SP.
ABSTRACT: This research was
aimed to found out the effect of fermented quail feces, bread waste, and tofu
and determine the best treatment to generate the biomass growth, and the
nutrition content of the Daphnia sp. This research used laboratory animals such
as Daphnia sp. and a container of concrete tanks as many as four. The methods
of this research was used experimental methods with Complete Randomize Design
with 4 treatments and population count repetition as 3 times with the density
of the Daphnia sp. was 100 ind./l. Treatments of this research were Tretment A
(0 % chicken mannure, 50 % tofu waste and 50 % bread waste), B (25 % chicken
mannure, 50 % tofu waste and 25 % bread waste), C (25 % chicken mannure, 25 %
tofu waste and 50 % bread waste, D (50 % chicken mannure, 25 % tofu waste and
25 % bread waste) with the total amount of the combination was 200 g/l. Data
which observed were population density, biomass, and nutrition content. The results
showed that the treatment of A was the lowest population density valued 548.67
ind / ml and the highest population density was on C treatment with a density
of 1328.67 ind / ml at the peak of the stationary phase. Biomass in treatment C
resulted in 336.30 grams and the treatment A yield 82.64 grams, and the content
of nutrients with the highest protein is found in the C treatment with a value
of 66.80%.
