Abstract

ABSTRACT

 

This study was aimed to improve the productivity of sludge worm (Oligochaetes) in culture systems using the addition of tapioca flour to the substrate to increase C/N ratio up to 10, 20, and 30. The substrate used was a mixture of mud and chicken manure with a ratio of 1:1 on the container measuring 100×12×15 cm3. Culture system used was a recirculation system. Initial stock of the worm was at density 150 g/m2. Results showed the highest population and biomass of the worm in each treatments was occurred on tenth day. The highest density of sludge worm, i.e. 421,145 ind/m2 with total biomass of 1,497.80 g/m2, was obtained on the treatment of C/N ratio at 20 (P <0.05).

ABSTRAK

 

Penelitian ini bertujuan untuk meningkatkan produktivitas cacing sutra (Oligochaeta) pada sistem budidaya dengan memperbaiki kualitas substrat cacing menggunakan penambahan tepung tapioka sehingga mencapai rasio C/N 10, 20, dan 30. Substrat yang digunakan yaitu campuran lumpur tanah dan kotoran ayam dengan perbandingan 1:1 pada wadah budidaya berukuran 100×12×15 cm3. Sistem budidaya yang digunakan yaitu sistem resirkulasi. Cacing dibudidayakan pada padat penebaran 150 g/m2. Hasil menunjukkan puncak populasi dan biomassa cacing sutra terjadi pada hari kesepuluh. Kepadatan cacing tertinggi, yaitu 421.145 ind/m2 dengan biomassa 1.497,80 g/m2, diperoleh pada perlakuan penambahan tepung tapioka dengan C/N rasio 20 (P<0,05).
