Performa Tumbuh Dan Kemampuan Degradasi Total Petroleum Hydrocarbon Dari Kayu Putih (Melaleuca Cajuputi) Pada Media Tanah Tercemar Minyak Bumi

Petroleum contamination is a serious threat to soil and water ecosystems and needs to be remedied immediately. Phytoremediation is a novel, eco-friendly, and cost-effective technology with great potential for remediating petroleum-contaminated soil. Thisstudy aimed to investigate the growth performance of Melaleuca cajuputi, its phytoremediation potential, and the effect of petroleum contamination on soil pH. A completely randomized design (CRD) pot experiment was conducted under greenhouse conditions. The soil was spiked with crude oil at five pollution levels (1%, 2%, 3%, 4%, and 5% w/w) and uncontaminated (0%) with four replications. Plant growth (shoot length, shoot diameter, plant dry weight, shoot-to-root ratio, leaf number), oil biodegradation, and changes in soil pH were analyzed. Results indicated that soil pH slightly increased across all treatments, with the most significant change observed at the highest contamination level (5%). Initial soil pH values ranged from slightly acid to moderately acid, but by the end of the experiment, they had improved, suggesting that M. cajuputi may contribute to enhancing soil conditions during phytoremediation. Petroleum contamination did not significantly affect seedling height and shoot-to-root ratio (p>0.05), indicating that M. cajuputi can tolerate contamination up to 5% oil concentration (TPH 2.23%). The reductions in seedling diameter, plant dry weight, and leaf number were observed as contamination levels increased. M. cajuputi demonstrated a significant TPH degradation, with efficiencies ranging from 18.86% to 28.19%. These findings highlight the potential of M. cajuputi not only as a phytoremediator but also in mitigating soil acidity in petroleum-contaminated soils.
