PENGARUH WAKTU FERMENTASI BAHAN ORGANIK (KOTORAN AYAM, AMPAS TAHU DAN ROTI AFKIR) SEBAGAI PUPUK UNTUK PERTUMBUHAN DAN KANDUNGAN PROTEIN DAPHNIA SP.
ABSTRACT: This
research aims to know the influence of the time of fermentation of organic
matter (chicken mature, tofu waste and bread waste) that’s different to protein
content of fertilizer of Daphnia sp.’s culture media and determine the best
treatment to produce the protein content of fertilizer of Daphnia sp.’s culture
media, growth, biomass and protein content on Daphnia sp.. This research used
laboratory animals such as Daphnia sp. and a container of concrete tanks as
many as 12. The methods of this research used experimental methods with
Complete Random Design with 4 treatments and 3 repetition with the density of
the Daphnia sp. was 100 ind./l with a dose of fertilizers is 25 % chicken
manure, 25 % tofu waste and 50 % bread the total amount of the combination was
2 g/l. Treatments of this research were Treatment A (0 days fermentation
without EM4), B (7 days fermentation), C (14 days fermentation), D (21 days
fermentation). The results showed that the treatment of C was the highest
protein content of fertilizer is 20.10%, population density valued 1036.73
ind/ml, biomass in treatment C resulted averaged in 130.40 gram, the content of
protein is 67.49%, specific growth rate with a value of 0.671/day. The
conclusion of this research that was found from the addition of the combination
organic material (chicken manure, tofu waste and bread waste) with different
fermentation time gave significant difference (P<0,01) on nutritional
fertilizers, growth, biomass, and nutrient contents of Daphnia sp.
