Abstract

Penelitian ini bertujuan untuk mengetahui kadar Pb (Timbal) pada Daun Tanaman Ubi (Manihot utilissima) yang terdapat di Kawasan jalan Lintas Medan-Siantar, Sei Rampah. Jenis penelitian ini adalah deskriptif dengan metode survei eksploratif. Pengukuran kadar timbal (Pb) dengan menggunakan Furnace (destruksi kering) dan Atomic Absorbance Spectrophotometer (AAS) di Balai Laboratorium Kesehatan Medan. Hasil penelitian kadar timbal (Pb) pada daun ubi (Manihot utilissima) paling tinggi adalah pada titik 1 pengulangan 1 sebesar 0,3045 mg/kg dan yang terendah kadar timbal (Pb) adalah titik 3 pengulangan 5 sebesar 0,0249 mg/kg.
