Abstract

Penelitian ini dilakukan untuk mengetahui pengaruh logam berat kadmium (Cd) dengan penambahan nitrogen terhadap kondisi ekofisiologis tanaman kangkung darat (Ipomoea reptans Poir.). Konsentrasi Cd yang digunakan yaitu 0,5 ppm dan 5 ppm sedangkan untuk penambahan nitrogen menggunakan 5 mM dan 10 mM (NH4)2 SO4. Perlakuan diberikan dalam  medium Hoagland selama 14 hari. Penambahan nitrogen 10 mM pada konsentrasi Cd 5 ppm paling menghambat pertumbuhan tanaman dengan indeks toleransi terkecil (15,61%) dan laju pertumbuhan relatif terendah (0,15 g/pekan). Penambahan luas daun paling tinggi pada perlakuan penambahan N 10 mM yaitu 34,86 cm2/pekan. Adanya penambahan Cd menyebabkan penambahan luas daun terhambat.  Kadar klorofil pada semua perlakuan tidak menunjukkan hasil yang berbeda signifikan tetapi pada perlakuan Cd dan penambahan N terjadi perubahan morfologi yaitu klorosis. Selain itu didapatkan kadar prolin pada akar yang lebih besar dibandingkan pada daun. Kadar prolin berada di kisaran 0,30- 1, 57 µmol/g  berat basah pada daun dan 0,61 – 4,13 µmol/g  berat basah pada akar.

Abstract

This study aims to explore the potential of using Napier grass (Pennisetum purpureum) as a low-cost alternative for treating wastewater contaminated with chromium (Cr) in the tannery industry. Traditional chemical treatment processes are costly, leading to many industries not committing to treatment. Phytoremediation, the use of plants to remove contaminants from the environment, could be a viable solution. The study conducted an experiment to test the tolerance and effectiveness of P. purpureum in treating wastewater containing Cr(VI) at concentrations of 20 ppm, 40 ppm, and tannery wastewater. The plant was grown in a constructed wetland pond using a batch system for 31 days. The results indicate that P. purpureum can survive and grow well in all treatments, showing tolerance to Cr. The plant's phytoremediation capacity was effective at 20 ppm of Cr(VI) as demonstrated by the chemical and physical characteristics of the medium (BOD, COD, pH, and TDS). The plant was able to remove a significant amount of total Cr and Cr(VI), with removal capacity ranging from 71.79% to 99.96%. The translocation factor (TF) for Cr in the roots was less than one, indicating that the plant has the potential to be used as a phytoremediator for Cr by accumulating it in its roots.
