Abstract

Pencemaran logam berat menjadi issue penting secara global terhadap masalah lingkungan, kese-hatan, ekonomi dan perencanaan. Mengingat Pb tergolong logam berat dengan sifat toksik tinggi, maka untuk menghilang Pb dari tanah perlu dilakukan remediasi secara fitoremediasi. Penelitian ini dilakukan di rumah bayang di kampus Program Pascasarjana, Universitas Sriwijaya. Metode yang digunakan yaitu penambahan logam Pb ke dalam media tanah sebanyak 319,71 mg.kg-1 dengan media tanah sebanyak 5 kg setiap perla-kuan. Setelah 60 hari tanam dilakukan analisa kandungan logam Pb pada media tanah dan tanaman dengan metode analisa AAS yang dilakukan di di laboratorium Jurusan Tanah, Fakultas Pertanian, Universitas Sriwi-jaya. Hasil yang diperoleh dari analisa laboratorium dilakukan perhitungan akumulasi logam Pb dengan faktor biokonsentrasi untuk mengetahui kemampuan tanaman dalam mengakumulasi logam Pb. Hasil penelitian me-nunjukkan bahwa kemampuan tanaman hias dalam menyerap logam Pb berbeda dan tergantung dengan je-nis tanaman. Tanaman Hanjuang (Cordyline fruicosa) mempunyai kemampuan menyerap logam Pb yang lebih tinggi dengan nilai 2,36 mg.kg-1.hari-1, diikuti oleh tanaman Sambang Dara (Excoecaria cochinensis) dengan nilai 1,70 mg.kg-1.hari-1. Tanaman yang paling rendah menyerap logam Pb adalah tanaman Lidah Mertua (Sanseviera trifasciata Prain) dengan nilai konsentrasi logam Pb yaitu 0,65 mg.kg-1.hari-1. Efisiensi penyerapan logam Pb oleh tanaman yang tertingi dimiliki oleh tanaman Hanjuang (Cordyline fruicosa) yaitu 44,28%. Per-tumbuhan tanaman selama 60 hari penelitian juga bervariasi dan tanaman yang memiliki pertumbuhan ter-baik adalah tanaman Hanjuang (Cordyline fruicosa). Dengan demikian, tanaman Hanjuang (Cordyline fruicosa) merupakan tanaman terbaik dalam menyerap logam Pb dalam tanah.

Abstract

Climate change greatly influences agricultural activities carried out by farmers in Indonesia. Farmers have begun to actively engage in organic farming, which is one of the production methods that is environmentally friendly, so that it can guarantee ecological sustainability. For this reason the study was conducted to determine the extent to which organic farming practices carried out by farmers can have implications for improving soil chemical properties and rice production. The method of this research is carried out by taking soil samples by surveying rice fields that apply organic systems and conventional systems. Data analysis using t test with a confidence level of 95%. The results showed that there were improvements in several soil chemical properties which included: organic C, total N, P available, K-dd and Al-dd soil, but improved soil chemical properties that were not significantly different from soil ph and soil CEC . To improve rice production, rice glucose content, root length, root volume and root dry weight there were significant improvements. Analysis of organic farming practices is important to limit the occurrence of all forms of environmental pollution that may be produced by conventional agricultural activities.
