Abstract

Heavy metal Cu is an essential metal required by living organisms but a pollutant in water environment when existed in a level above the treshold level. The capability of sponge Clathria reinwardtii in accumulating heavy metals was analyzed according to modified Müller et al. (1998) method, and the sediment was analyzed according to Loring and Rantala in Rochyatun et al., (2006). Cu concentrations were measured by ICP-OES. The results indicate that Clathria reinwardtii was capable of accumulating the highest Cu level compared to other sponges. The highest Cu level analyzed in Clathria reinwardtii was 161.3 mg/kg.

Abstract

A research on essential metal distribution of copper in Spermonde waters has been carried out. Sponge species of Melophlus sarassinorum, Callyspongia aerizusa, dan Clathria reinwardtii were identified and analyzed accordingly. Copper level were measured using Inductrively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) and the results showed that highest concentration was found in Clathria reinwartii  48.3 ppm. Copper distribution in sponge skeleton is higher than in its tissue and seemingly in terms of species the highest concentration is Clathria reinwartii taken from Barrang Lompo waters. In the meantime, Samalona waters contain highest concentration in its sedimen (3.96 ppm). Apparently Spermonde waters is beginning being interferred by metal pollution.

Abstract

Perairan laut menjadi tempat pembuangan limbah dari berbagai kegiatan manusia yang dapat mencemari laut. Adanya logam berat diperairan berbahaya baik secara langsung ataupun tidak langsung terhadap kehidupan organisme. Salah satu logam berat yang berdampak negatif bahkan dapat mematikan organisme perairan laut adalah logam berat timbal (Pb). Spons (porifera) dan sedimen laut adalah salah satu jenis organisme diperairan laut yang terakumulasi logam berat Pb. Penelitian ini dilakukan untuk mengetahui akumulasi logam berat Pb pada spons (porifera) dan sedimen laut yang ada di perairan Pulau Samalona dengan metode Spektrofotometri Serapan Atom. Hasil yang diperoleh dari penelitian ini menunjukkan bahwa spons (porifera) jenis Clathria reinwardhi, Callyspongia aerizuza, Haliclona fascigera dan sedimen laut mampu mengakumulasi logam berat Pb pada. Konsentrasi logam berat Pb di Pulau Samalona untuk jenis Clathria reinwardhi sebesar 11,22 ppm, Callyspongia aerizuza sebesar 11,99 ppm dan Haliclona fascigera sebesar 7,76 ppm, sementara untuk sedimen sebesar 13,73 ppm. Selain air laut, kandungan logam berat Pb dalam sedimen memberikan pengaruh yang cukup besar terhadap tinggi rendahnya kandungan logam berat Pb dalam spons (porifera).

Abstract

Industri tekstil menggunakan air yang cukup besar untuk proses pengolahannya yakni sekitar 280 m3/500 kg kain jadi. Air buangan industri tersebut dapat menimbulkan masalah bagi lingkungan perairan. Adsorpsi dengan arang aktif merupakan metode yang banyak digunakan. Pada penelitian ini arang aktif yang digunakan adalah arang dari kayu bakau. Konsentrasi larutan adsorbat mempengaruhi proses adsorpsi. Semakin tinggi konsentrasi larutan adsorbat maka semakin banyak pula adsorbat yang dapat diadsorpsi oleh adsorben. Tetapi bila adsorben sudah jenuh maka konsentrasi adsorbat tidak lagi berpengaruh. Arang kayu bakau mampu mengadsorpsi zat warna Eryonil Brill Blue sampai konsentrasi 1500 ppm dengan waktu optimum 2 jam untuk bagian batang dan waktu optimum 3 jam untuk bagian akar.
