Awaliyah, Hikmah Farda (2017) Analisis Konsentrasi Pb Dan Cu Serta Gambaran Histologi Akar Dan Daun Avicennia Marina Sebagai Agen Fitoremidiasi Logam Berat Di Ekosistem Mangrove Kali Lamong, Jawa Timur. Sarjana thesis, Universitas Brawijaya.

Abstract

Ekosistem mangrove Kali Lamong terletak di area yang padat aktivitas manusia seperti aktivitas industri, lalu lintas yang padat, pemukiman dan pelabuhan. Hal tersebut memicu masukan logam berat Pb dan Cu di Kali Lamong. Ekosistem mangrove dapat dikembangkan sebagai pengendalian pencemaran logam berat dan dapat juga digunakan sebagai pollutant trap. Polutan yang terserap dapat mempengaruhi pertumbuhan dan anatomi mikroskopis yang dapat dilihat melalui pengamatan histologi jaringan. Penelitian ini bertujuan untuk mengetahui kemampuan Avicennia marina dalam menyerap logam berat Pb dan Cu beserta gambaran histologi akar dan daun di ekosistem mangrove Kali Lamong. Hasil konsentrasi logam berat di air (Pb=0,22 ppm ± 0,03 dan Cu=0,025 ppm ± 0,01) lebih rendah daripada konsentrasi di sedimen (Pb=28,04 ± 4,21 dan Cu=13,31 ppm ± 1,20). Perbandingan konsentrasi di daun lebih besar (Pb=2,30 ppm ± 0,26 dan Cu=7,76 ppm ± 0,36) dibandingkan konsentrasi di akar (Pb=2,00 ppm ± 0,51 dan Cu=7,17 ppm ± 0,61). Avicennia marina di lokasi penelitian bersifat excluder karena nilai BCF<1 (BCF Pb=0,16 dan BCF Cu=0,26), fitoekstraksi karena nilai TF>1 (TF Pb=1,19 dan TF Cu=1,03) dan kemampuan fitoremidiasi belum maksimal karena nilai FTD negatif (FTD Pb=-1,03 dan FTD Cu=-0,56). Hasil Analisa histologi akar dan daun didapatkan beberapa kerusakan yakni pada akar terjadi penebalan eksodermis, sel immature, bercak hitam dan perubahan struktur xilem, sedangkan pada daun terjadi penambahan jaringan vaskuler dan bercak hitam pada glandular trikoma.

English Abstract

Mangrove ecosystem of Kali Lamong is located in an area with dense human activities such as industrial, heavy traffic, settlements and harbour activities. These activities could triggered the input of heavy metals (Pb and Cu) in Kali Lamong. Mangrove ecosystem can be developed as a control of heavy metal pollution and also as a pollutant trap. The absorbed pollutants can affect microscopic growth and anatomy which can be seen through histological observation of the tissues. The aim of this study was to determine the ability of Avicennia marina in absorbing heavy metals (Pb and Cu) along with its histology of roots and leaves. The result showed that heavy metal concentrations in the water (Pb = 0.22 ppm ± 0.03 and Cu = 0.025 ppm ± 0.01) was lower than the concentration in the sediment (Pb = 28.04 ± 4.21 and Cu = 13.31 ppm ± 1.20). The concentration in the leaves was higher (Pb = 2.30 ppm ± 0.26 and Cu = 7.76 ppm ± 0.36) than the concentration in the roots for both heavy metals (Pb = 2.00 ppm ± 0.51 and Cu = 7.17 Ppm ± 0.61). Avicennia marina in the study site was categorized as excluder based on BCF<1 (BCF Pb = 0.16 and BCF Cu = 0.26), phytoextraction due to TF>1 (TF Pb = 1.19 and TF Cu = 1.03) and phytoremidiation ability was not optimal (FTD Pb = -1.03 and Cu-FTD = -0.56). The result of histology analysis of roots and leaves showed some damages in roots such as exodermis thickening, immature cell, black spots and change of xilem structure, whereas an addition of vascular tissue and black spot on glandular trichoma were found in the leaves.
