Abstract: Sunflowers ((Helianthus annuus L) is a plant that has the ability to absorb metals in polluted soil or environment. This study aims to determine the ability of sunflower plants to absorb lead (Pb) in the soil. This research method use a Completely Randomized Design (CRD). Pb metal analysis was carried out by testing the lrvels using the Atomic Absorption Spectrophotometry (AAS) tool in the Chemical Laboratory (LABKES). The results showed that the highest absorption of Pb contamination in P2L2 treatment (2.0 ppm) as much as 5.04 ppm and the lowest absorption of metals in the treatment P1L1 (0.3 ppm) yielded as much as 0.52 ppm Pb metal content. So from the results of these studies it can be concluded that sunflower plants can be used as phytoremediation pf Pb metal.
Description: Bunga matahari (Helianthus annuus L) adalah tanaman yang memiliki kemampuan untuk menyerap logam di lingkungan atau tanah tercemar. Penelitian ini bertujuan untuk mengetahui kemampuan tanaman bunga matahari dalam penyerapan kandungan logam timbal (Pb) di tanah. Metode penelitian ini menggunakan Rancangan Acak Lengkap (RAL). Analisis logam Pb dilakukan dengan menguji kadar menggunakan alat Atomic Absorption Spektrofotometri (AAS) di Laboratorium Kimia (LABKES). Hasil penelitian menunjukkan bahwa penyerapan cemaran Pb tertinggi pada perlakuan P2L2 (2,0 ppm) sebanyak 5,04 ppm dan penyerapan logam terendah pada perlakuan P1L1 (0,3 ppm) menghasilkan sebanyak 0,52 ppm kandungan logam Pb. Maka dari hasil penelitian tersebut dapat disimpulkan bahwa tanaman bunga matahari dapat digunakan sebagai fitoremediasi bahan logam Pb.
