Abstract
Tanaman jarak pagar (Jatropa curcas L.) merupakan salah satu tanaman yang mudah tumbuh di Indonesia dan memiliki potensi yang cukup besar untuk dikembangkan sebagai bahan baku perindustrian di masa depan. Hasil olahan dari tanaman ini yang sekarang terkenal yaitu biodiesel akan tetapi juga ada produk samping lain yaitu arang aktif yang berasal dari tempurung bijinya. Dalam percobaan ini tempurung biji jarak diaktifkan terlebih dahulu dengan larutan ZnCl2 dengan konsentrasi 0,25 N. Proses berikutnya yaitu diarangkan dengan furnace dengan suhu 450°. Tempurung biji jarak dihancurkan menjadi serbuk berukuran 100 mesh.. Model adsorbsi didekati dengan persamaan Langmuir dan Freundlich, pengukuran konsentrasi logam timbal dilakukan dengan menggunakan alat ICPS. Dari penelitian ini dapat diketahui bahwa produk yang dihasilkan layak diproduksi karena telah sesuai dengan standar yaitu SII 0258-79 & 88, diperoleh kondisi optimum adsorbs logam timbal pada arang tempurung biji jarak pada konsentrai 14 ppm dengan waktu pengocokan 120 menit dan massa adsorben 2 gr yaitu sebesar 73,976357146%, model adsorbsi logam timbal pada arang tempurung biji jarak mengikuti model Langmuir dengan persamaan y=4482,5x-780,55 dan R2 = 0,9455

Jatropha curcas (Jatropa curcas L.) is one of the easiest plants to grow in Indonesia and has considerable potential to be developed as an industrial raw material in the future. The processed product of this plant which is now well-known is biodiesel, but there is also another by-product, namely activated charcoal which comes from the seed shell. In this experiment, the castor seed shells were activated first with a ZnCl2 solution with a concentration of 0.25 N. The next process was charred in a furnace with a temperature of 450°. The castor seed shell was crushed into a 100 mesh sized powder. The adsorption model was approximated by the Langmuir and Freundlich equations, measurements of lead metal concentrations were carried out using the ICPS tool. From this research it can be seen that the resulting product is feasible to produce because it complies with the standard, namely SII 0258-79 & 88, the optimum conditions for lead metal adsorption on castor seed shell charcoal at a concentration of 14 ppm with a shaking time of 120 minutes and an adsorbent mass of 2 gr are obtained, namely of 73.976357146%, the adsorption model of lead metal on castor seed shell charcoal follows the Langmuir model with the equation y=4482.5x-780.55 and R2 = 0.9455
