PENGARUH PEMBERIAN TELUR ITIK DAN TEPUNG
JAGUNG (MAIZENA) TERHADAP LAJU PERTUMBUHAN
POPULASI Daphnia sp.
ABSTRAK
Penelitian mengenai pengaruh pemberian telur itik dan tepung jagung (maizena)
terhadap laju pertumbuhan populasi daphnia sp. telah dilakukan pada bulan April
hingga Mei 2015 menggunakan metode rancangan acak lengkap. Daphnia sp.
dikultur dalam media kultur (toples kaca) yang masing-masing diberikan air
sebanyak 1 liter dan kotoran ayam sebanyak 2,4 gr/L, kemudian masing-masing
toples diisi Daphnia sp. sebanyak 100 individu, diberikan perlakuan sebanyak 4
perlakuan; perlakuan A tanpa penambahan kombinasi telur itik dan tepung jagung,
perlakuan B (kombinasi tepung jagung 0,9 gr/L dan telur itik 0,3 gr/L), perlakuan
C (kombinasi tepung jagung 0,6 gr/L dan telur itik 0,6 gr/L), perlakuan D
(kombinasi tepung jagung 0,3 gr/L dan telur itik 0,9 gr/L), tiap perlakuan diulang
sebanyak 3 kali, diaerasi dan diamati populasinya selama 16 hari. Berdasarkan
hasil penelitian diperoleh pertumbuhan tertinggi pada perlakuan D (kombinasi
tepung jagung 0,3 gr/L dan telur itik 0,9 gr/L) yaitu sebanyak 2.468 ind/L. Dari
penelitian didapatkan hasil bahwa pemberian kombinasi pakan dengan
menggunakan tepung jagung dan telur itik (perlakuan D) tidak memberikan
pengaruh yang nyata terhadap jumlah populasi Daphnia sp..

RESEARCH ON THE EFFECT OF DUCK EGGS AND CORN
FLOUR (CORNSTARCH) ON THE RATE OF POPULATION
GROWTH OF Daphnia sp.
ABSTRACT
Research on the effect of duck eggs and corn flour (cornstarch) on the rate of
population growth of Daphnia sp. was conducted from April until May 2015
using completely randomized design method. Daphnia sp. was cultured in the
medium culture that consisted of 1 liter of water and 2.4 g/L chicken’s manure,
then each jar were filled by 100 individuals of Daphnia sp., and given a treatment
with 4 treatments; A treatment was without combination of corn flour and duck
eggs (as control), B treatment (a combination of corn flour 0,9 g/L and 0,3 g/L
duck eggs), C treatment (a combination of corn flour 0,6 g/L and duck eggs 0,6
g/L), D treatment (a combination of corn flour 0,3 g/L and 0,9 g/L duck eggs),
each treatments were repeated by 3 times, aerated and population observed for 16
days. The research showed the highest growth in treatment D (a combination of
corn flour 0.3 g/L and duck eggs 0.9 g/L) were given by 2,468 ind/L. The research
analyzed that combination of feed using corn flour and duck eggs (treatment D)
does not give a significant impact on the rate of population growth of Daphnia
sp..
