Abstract

Penelitian ini bertujuan untuk menurunkan konsentrasi kromium (Cr⁶⁺) dalam tanah dengan dan tanpa penambahan kompos menggunakan tanaman jarak pagar (*Jatropha curcas* L.). Penelitian dilakukan di rumah kaca meliputi range finding test dan tes definitif untuk menentukan variasi konsentrasi kromium (Cr⁶⁺). Hasil dari range finding test menunjukkan bahwa tanaman jarak pagar dapat meremediasi tanah tercemar kromium (Cr⁶⁺) dengan konsentrasi kurang dari 90 mg/kg. Waktu paro penurunan (t-50) kromium (Cr⁶⁺) menunjukkan korelasi yang signifikan terhadap konsentrasi kromium di media. Efek konsentrasi 50 (EC-50) kromium (Cr⁶⁺) pada berat kering tanaman jarak pagar di tanah tanpa kompos dan dengan penambahan kompos sebesar 82 mg/kg dan 88 mg/kg. Tidak ditemukan pengaruh yang signifikan pada bagian tanaman jarak pagar. Kompos sebaiknya ditambahkan pada saat tanaman jarak pagar ditanam pada tanah tercemar kromium (Cr⁶⁺).

This paper reports an assessment of hexavalent chromium removal from soil with and without compost amendment by *Jatropha curcas*. Greenhouse experiment was conducted and consisted of range finding test and definitive test for various concentrations of hexavalent chromium. Result of range finding test showed that both plants were able to remediate hexavalent chromium-polluted soil of less than 90 mg/kg. The removal half time (t-50) of hexavalent chromium correlated significantly with the initial hexavalent chromium concentration in the media. Effect concentration fifty (EC-50) of hexavalent chromium for plant dry matter (RDM) *Jatropha* in soil without compost and with compost was 82 mg/kg and 88 mg/kg. No significant effect was found for aerial plant parts of *Jatropha*. Compost amendment was preferable when *Jatropha* was planted in hexavalent chromium-polluted soil.
