Abstract
ABSTRAKThis study aims to determine the best dose of bakers yeast in culture Brachionus
plicatilis. The research was conducted in July-September 2015 in the Mandiri Laboratory of
BTN Puri Meninting West Lombok District. This experiment uses a completely randomized
design ( CRD ), which consists of 6 treatments and repeated 3 times , in order to obtain 18
units of trial that treatment A : without feed , treatment B : feed Nannochloropsis spp.,
treatment C : 7.5 mg/L, treatment D : 15.0 mg/L , treatment E : 22.5 mg/L , and treatment F :
30.0 mg/L. The results showed that the difference in the level of baker's yeast significantly
affect the population growth of Brachionus plicatilis, which obtained the highest population
density in the yeast dose of 30.0 mg/L of 90 individuals/mL
Key word : bakers yeast, population growth, Brachionus plicatilis
ABSTRACT
Penelitian ini bertujuan untuk mengetahui dosis ragi roti yang terbaik dalam kultur
Brachionus plicatilis. Penelitian dilaksanakan pada bulan Juli - September 2015 di
Laboratorium Mandiri BTN Puri Meninting Kabupaten Lombok Barat. Penelitian ini
menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari 6 perlakuan dan diulang
sebanyak 3 kali, sehingga diperoleh 18 unit percobaan yaitu perlakuan A : tanpa pakan,
perlakuan B : pakan Nannochloropsis spp., perlakuan C : 7,5 mg/L, perlakuan D : 15,0
mg/L, perlakuan E : 22,5 mg/L, dan perlakuan F : 30,0 mg/L. Hasil penelitian menunjukan
bahwa perbedaan dosis ragi roti berpengaruh nyata terhadap pertumbuhan populasi
Brachionus plicatilis, dimana kepadatan populasi tertinggi diperoleh pada dosis ragi 30,0
mg/L yaitu 90 individu/mL
Kata kunci : ragi roti, pertumbuhan populasi, Brachionus plicatilis,
