Abstract

Fitoremediasi adalah penggunaan tumbuhan untuk menghilangkan, menstabilkan, atau menghancurkan kontaminan, baik organik maupun anorganik, dalam tanah, sedimen, dan air. Penelitian ini bertujuan untuk mengkaji pengaruh logam berat Pb, Cd, dan kombinasinya terhadap tinggi tanaman, luas daun, pH tanah, dan CO₂; mengetahui nilai persentase reduksi tanah tercemar Pb dan Cd oleh jarak pagar; mengkaji kemampuan jarak pagar dalam mengakumulasi Pb dan Cd; serta mengetahui nilai persentase akumulasi Pb dan Cd dalam jarak pagar.
Bahan yang digunakan dalam penelitian ini adalah Pb(NO₃)₂, Cd(NO₃)₂·4H₂O, tanaman jarak pagar, dan tanah taman. Variabel yang digunakan meliputi jenis logam berat (Pb dan Cd); variasi konsentrasi Pb dan Cd; serta kombinasi Pb dan Cd (Pb:Cd = 50%:50%, Pb:Cd = 75%:25%, dan Pb:Cd = 25%:75%). Parameter yang diuji meliputi tinggi tanaman, luas daun, pH tanah, CO₂, berat kering tanaman, serta konsentrasi logam berat Pb dan Cd pada tanah dan tanaman.
Hasil penelitian menunjukkan bahwa Pb, Cd, dan kombinasinya berpengaruh terhadap tinggi tanaman, luas daun, pH tanah, dan CO₂; nilai persentase reduksi tanah tercemar logam berat Pb dan Cd oleh jarak pagar, yaitu 84–98% untuk Pb; 76–91% untuk Cd; dan 75–92% Pb : 74–92% Cd; jarak pagar (Jatropha curcas Linn.) mempunyai kemampuan dalam mengakumulasi Pb dan Cd; dan nilai persentase akumulasi logam berat Pb dan Cd dalam jarak pagar adalah 1–45% untuk Pb; 46–125% untuk Cd; dan 0,49–39% Pb : 16–236% Cd.

Phytoremediation is a method in which plants are used to remove, stabilize, and eradicate organic and inorganic contaminants in soil, sediment, and water. This research aims to examine the effects of Pb, Cd, and their combinations on plant height and width, soil pH, and CO₂; determine the percentage of reduction of Pb- and Cd-contaminated soil by Jatropha curcas; examine the capability of Jatropha curcas in accumulating Pb and Cd from contaminated soil; and determine the percentage of Pb and Cd accumulation within Jatropha curcas.
Pb(NO₃)₂, Cd(NO₃)₂·4H₂O, Jatropha curcas, and soil were used to achieve the objectives of this research. Several variables were involved, including heavy metal types such as Pb and Cd, variations in Pb and Cd concentrations, and combinations of Pb and Cd (Pb:Cd = 50%:50%, Pb:Cd = 75%:25%, and Pb:Cd = 25%:75%). The parameters measured included plant height and width, soil pH, CO₂, dry weight of plants, and the concentrations of Pb and Cd in plants and soil.
This research shows that Pb, Cd, and their combinations affect plant height and width, soil pH, and CO₂; the percentage of reduction of Pb- and Cd-contaminated soil is 84–98% for Pb, 76–91% for Cd, and 75–92% Pb : 74–92% Cd; Jatropha curcas has the capability to accumulate Pb and Cd; and the percentage of Pb and Cd accumulation in Jatropha curcas is 1–45% for Pb, 46–125% for Cd, and 0.48–39% Pb : 16–236% Cd.
