Abstract
Lumpur hasil pengolahan air limbah memiliki kandungan
bakteri pathogen, sehingga diperlukan penanganan lebih lanjut
yang menelan biaya hingga 60% dari total biaya operasional
IPAL. Dibutuhkan alternatif pengolahan agar volume lumpur
yang harus diolah dapat diminimalisasi. Di identifikasi golongan
Oligochaeta memiliki kemampuan dalam mereduksi lumpur.
Penelitian ini bertujuan untuk mengetahui tingkat reduksi lumpur
yang dapat dilakukan oleh cacing akuatik golongan Oligochaeta,
Tubifex sp. dan Lumbriculus sp. menggunakan parameter TSS
dan COD.
Penelitian dilakukan skala laboratorium dengan reaktor
cacing sistem batch. Lumpur yang digunakan berasal dari unit
bangunan slugde drying bed outlet pipa lumpur bak pengendap II
(secondary sludge). Lumpur yang diamati dimasukkan dalam
reaktor dan ditambahkan cacing akuatik sesuai penggunaan
variasi. Rasio perbandingan antara worm:sludge dan jenis cacing
digunakan sebagai variasi dalam penelitian ini.
Berdasarkan penelitian yang telah didapatkan hasil bahwa
reaktor cacing memiliki kemampuan mereduksi TSS hampir dua
kali lipat lebih tinggi dibandingkan reaktor tanpa cacing. Reduksi
tertinggi berada pada rasio perbandingan w/s 0,4. Reduksi
tersebut dikarena cacing memanfaatkan kandungan organik pada
lumpur sebagai sumber nutrisi. Disisi lain terjadi peningkatan
kandungan organik pada reaktor cacing Hal tersebut dikarenakan
pemisahan antara fases dan lumpur tidak terjadi secara sempurna

In general, sludge from wastewater treatment still
contains pathogens, so that require further treatment which spent
cost up to 60% of total operating WWTP costs. Treatment
alternatives are needed in order to minimize the volume of sludge
which processed. Some studies said that class of Oligochaeta
natural predators have ability to reduce sludge. This research aims
to determine the level of sludge reduction that can be performed
by an aquatic worm Oligochaeta class with Tubifex sp. and
Lumbriculus sp. using TSS and COD parameters.
The research was conducted in a laboratory-scale batch
reactor worms system. Sludge used is sludge in slugde drying bed
unit derived from the settling basin outlet pipe mud II (sedondary
sludge). The sludge that observed, inserted in the reactor and
addedappropriate variations of aquatic worms. The ratio of the
worms: sludge (w/s) and worms are used as a variation in this
research.
The research result showed that the worm has the ability
to reduce the TSS is almost twice higher than the reactor without
worms. The highest reduction capabilities are in the ratio w/s 0,4.
The reduction occur because the worms exploit the organic
content which contained in the sludge as a source of nutrients for
themselves. However, an increase in the organic content in the
reactor worms and this condition occur because the separation
between feces and the sludge happened with imperfect
