AFRIANISA, RO`DU DHUHA ( 3310100041 )




ABSTRAK

Tubifex sp. dan Lumbriculus sp. mampu mengakumulasi logam secara biologis yang selanjutnya dapat terjadi pengurangan logam berat dalam lumpur. Lumpur hasil pengolahan limbah industri sering mengandung logam berat polutan organik dan bakteri patogen. Fe besi merupakan logam bila dalam jumlah besar di lingkungan dapat menyebabkan toksik. Hasil analisis kadar logam dalam salah satu lumpur limbah mengandung Fe sebesar 17.100 mgkg. Pengelolahan lumpur menggunakan cacing akuatik merupakan alternatif dalam mengurangi jumlah lumpur yang dihasilkan dari suatu instalasi pengolahan air limbah. Penelitian ini dilakukan dalam skala laboratorium dengan sistem batch. Sampel lumpur berasal dari hasil pengolahan limbah pada unit instalasi secondary treatment IPAL PT. SIER diolah dalam reaktor berisi cacing. Reaktor untuk tiap sampel menggunakan rasio wormsludge ws 04 06 dan 08. Akumulasi logam Fe pada cacing dilakukan selama 7 hari dengan pengamatan setiap hari. Hasil yang diperoleh dari penelitian ini jumlah logam Fe yang terkandung dalam tubuh cacing Tubifex sp. dan Lumbriculus sp. akibat proses reduksi lumpur masing-masing sebesar 6.198mgkg atau dan 2.036mgkg. Wormsludge dan jenis cacing mempengaruhi akumulasi logam Fe oleh cacing akuatik.


ABSTRACT

Tubifex sp and Lumbriculus sp. sp biologically able to accumulate metals which can occur subsequent reduction of heavy metals in the sludge. Industrial sewage sludge processing results often contain heavy metals organic pollutants and pathogens. Fe iron is a metal which in large quantities in the environment can cause toxic. The result analysis levels metal in mud containing Fe as much as 17.100 mgkg. Improper processing can have an impact on the environment and human health. Sludge treatment using aquatic worms are an alternative to reduce the amount of sludge produced from the wastewater treatment plant. This research was conducted in laboratory scale with a batch system. Samples of the mud comes from the results of the installation unit on sewage treatment secondary treatment IPAL PT. SIER wich then inserted in the reactor containing worm. Reactor for each sample used a ratio of wormsludge ws thas is 04 06 dan 08. The accumulation of metal in worms carried for 7 days with daily observations. The results obtained from this study the amount of Fe contained in the body of worms Tubifex sp. and Lumbriculus sp. due to sludge reduction processes respectively at 6.198 mgkg and 2.036 mgkg. Wormsludge and types of worms affecting Fe metal accumulation by aquatic worms.
