Abstract

Penelitian ini untuk mengamati kemampuan sekam padi dalam bioremediasi stimulasi tanah tercemar kromium. Variasi konsentrasi tanah tercemar kromium (VI), antara 10 mg/kg sampai 90 mg/kg dan tanpa sekam padi. Dilakukan komposisi media dengan rasio sekam banding tanah 0,4 dan 0,15. Dalam persentase rasio C/N 70% lebih tinggi dari level awal, menyebabkan mikroorganisme tempatan tumbuh pada minggu ketiga lebih tinggi daripada dua minggu sebelumnya. Dalam waktu yang sama, penurunan Cr (VI) meningkat dengan signifikan. Sekam padi mampu menaikkan jumlah mikroorganisme dan meningkatkan penurunan kromium.

The research investigated the capacity of rice husk for stimulating bioremediation of chromium-polluted soil. Various levels of Cr (VI)-polluted soil, ranging from 10 to 90 mg/kg, were amended with rice husk. The treated media were composed of husk/soil ratios of 0.40 and 0.15. In the presence of a C/N ratio 70% higher than the initial level, indigenous microbes grew three times higher than their initial numbers during the first two weeks. At the same period, chromium removal increased sharply. Rice husk brought about an increased removal half-time (t-50) for microbes, and t-50 decreased for chromium removal.
