Pengaruh Perbedaan Konsentrasi Pupuk Organik Cair terhadap Biomassa dan Populasi Cacing Sutera (Tubifex SP.)

Abstract

The research aims to know the influence of different liquid organic fertilizer concentrations on the population and biomass of silk worms (Tubifex sp.). Research was conducted in the field laboratory of BDP – Panteriek, Lueng Bata District, Banda Aceh in February 2016. This research used the experimental method with Completely Randomized Design. The different concentrations were : 0, 5, 10, 15 ml, for 30 days. The results showed that the biomass ranged from 2,70 ± 0,16 to 16,27 ± 0,83 g, the silk worms population ranged from 6.784 ± 83 to 14.029 ± 445 ind. The highest values for all parameters were obtained at treatment D which was 15 ml. The ANOVA showed that the adding of organic liquid fertilizers has significant effect againt the biomass and population of silk worms (Tubifex sp.). Duncan's test showed that the value of the biomass and population of silk worms (Tubifex sp.) on treatment D (15 ml) showed significant different to other treatments. Based on the results of the study it can be concluded that the addition of liquid organic fertilizers increase the production of biomass and population of the silk worms (Tubifex sp.)
