Abstract

Phytoremediationn of Cadmium (Cd) Contaminated Soil using Hanjuang Plants (Cordyline fruticosa)Phytoremediation of Cadmium (Cd) contaminated soil using ornamental plants is one method that applicable and environmental friendly in the process absorption of metal in the soil. This study aims to determine the effectiveness of phytoremediation and the potential of hanjuang plants as phytoremediation agents for cadmium metals. Hanjuang plants are planted on soil media which is previously added to heavy media as pollutants, namely Cd(NO3)2 with a concentration of 0; 50; 100; 150 mg/Kg for 42 days. Measurement of Cd concentration uses Inductively Coupled Plasma Optical Emission Spectrometry instrument. The results showed that hanjuang plants could accumulate cadmium metals in the roots. The highest accumulation is found in the roots of plants at 150 mg/Kg concentration and the result is 36.2167 mg/Kg, whereas in the stems and leaves of plants is not found heavy metal absorptions. Hanjuang plants contaminated with cadmium metal have a bioconcentration value (BCF)<1 so that they are included in the metal excluder group or low accumulator. The highest distribution of cadmium metal concentration is in the roots with transport factor (TF)<1 so that hanjuang plants are included in phytoremediation plants with their metal absorption which mechanism is phytostabilization.Keywords : Cordyline fruticosa, Phytoremediation, Cadmium, ICP-OESABSTRAKFitoremediasi tanah tercemar logam Kadmium (Cd) menggunakan tanaman hias merupakan salah satu metode yang aplikatif dan ramah lingkungan dalam proses penyerapan logam di dalam tanah. Penelitian ini bertujuan untuk mengetahui efektivitas fitoremediasi dan potensi tanaman hanjuang sebagai agen fitoremediasi dalam menyerap logam kadmium. Tanaman hanjuang ditanam pada media tanah yang sebelumnya media tanah tersebut ditambahkan logam berat sebagai pencemar yaitu Cd(NO3)2 dengan variasi konsentrasi 0; 50; 100; 150 mg/Kg selama 42 hari. Pengukuran konsentrasi Cd menggunakan instrumen Inductively Coupled Plasma Optical Emission Spectrometry. Hasil penelitian menunjukkan tanaman hanjuang dapat mengakumulasi logam kadmium pada bagian akar. Akumulasi tertinggi ditemukan pada bagian akar tanaman pada konsentrasi 150 mg/Kg sebesar 36,2167 mg/Kg, sedangkan pada bagian batang maupun daun tanaman tidak ditemukan adanya penyerapan. Tanaman hanjuang yang terkontaminasi oleh logam kadmium memiliki nilai biokonsentrasi (BCF)<1 sehingga termasuk ke dalam kelompok metal excluder atau akumulator rendah. Distribusi konsentrasi logam kadmium paling tinggi terdapat pada bagian akar dengan faktor transport (TF)<1 sehingga tanaman hanjuang termasuk ke dalam tanaman fitoremediasi dengan mekanisme penyerapan logamnya yaitu fitostabilisasi.Kata kunci : Cordyline fruticosa, Fitoremediasi, Kadmium, ICP-OES.
