Abstract
Indonesia merupakan negara produsen bauksit terbesar nomor enam di dunia dengan tercatatnya sumber daya bauksit sebesar 828.289.086 ton bijih. Saat ini, hanya sekitar 10% dari red mud dihasilkan tiap tahunnya yang didaur ulang. Lebih dari 150 megaton red mud setiap tahunnya disimpan di tempat pembuangan sampah dan laut. Red mud menjadi perhatian karena kandungan logam beratnya yang sangat tinggi dan mempunyai nilai ekonomis yang tinggi. Penelitian kali ini bertujuan untuk menentukan kemampuan tumbuhan Tradescantia pallida dan Philodendron burle-marxii dalam melakukan phytomining unsur kromium dan vanadium pada red mud dan menentukan pengaruh penambahan pupuk kandang sapi dan bakteri Bacillus stercoris terhadap kemampuan phytomining tumbuhan Tradescantia pallida dan Philodendron burle-marxii. Penelitian terdiri dari penelitian pendahuluan dan utama. Penelitian pendahuluan meliputi screening tumbuhan, pemilihan stimulan terbaik, dan uji ICP-OES untuk tumbuhan uji yang tidak tersedia lite atur akumulasi logam berat. Penelitian utama dilakukan selama 28 hari dengan periode pengambilan sampel sebanyak 5 kali. Parameter pendukung yang diukur pada penelitian utama adalah pH, soil moisture, electrical conductivity, suhu, morfologi tumbuhan, total klorofil, serta berat basah dan kering. Uji TPC dilakukan sebanyak 2 kali yakni pada hari ke-0 dan hari ke-28 untuk mengetahui perkembangan koloni bakteri yang ditambahkan. Penelitian ini memberikan hasil bahwa perlakuan penambahan bakteri memberikan dampak yang sangat signifikan terhadap kemampuan uptake tumbuhan. Penyerapan Cr terbesar dengan penambahan bakteri hingga 82,2 mg/kg oleh tumbuhan Tradescantia pallida sedangkan penyerapan Cr terbesar tanpa penambahan bakteri hanya 53,3 mg/kg oleh tumbuhan yang sama. Hasil yang sama pada logam V penyerapan terbesar dengan perlakuan bakteri mencapai 63,8 mg/kg dan tanpa bakteri sebesar 54,6 mg/kg oleh tumbuhan Tradescantia pallida. Namun, penambahan bakteri tidak memberikan dampak yang positif terhadap nilai parameter pendukung seperti electrical conductivity dan pH. Peran stimulant pupuk kandang sapi lebih terlihat dominan dibandingkan dengan bakteri terhadap parameter tersebut.

Indonesia is the sixth-largest producer of bauxite in the world, with recorded bauxite resources amounting to 828.289.086 tons of ore. Currently, only about 10% of the red mud generated annually is recycled. More than 150 megatons of red mud are stored in landfills and oceans each year. Red mud has garnered attention due to its high heavy metal content and significant economic value. This study aims to determine the ability of Tradescantia pallida and Philodendron burle-marxii plants to perform phytomining of Chromium and Vanadium in red mud and to evaluate the effect of adding cow dung manure and Bacillus stercorisbacteria on the phytomining ability of Tradescantia pallida and Philodendron burle-marxii. The research consists of preliminary research and main research. The preliminary research includes plant screening, selection of the best stimulants, and ICP-OES testing for test plants without available literature on heavy metal accumulation. The main research was conducted over 28 da ys with a sampling period of 5 times. Supporting parameters measured in the main research include pH, soil moisture, electrical conductivity, temperature, plant morphology, total chlorophyll, as well as wet and dry weight. The TPC test was conducted twice, on day 0 and day 28, to observe the development of the added bacterial colonies. This study demonstrates that the treatment involving the addition of bacteria has a highly significant impact on the uptake ability of plants. The highest Cr uptake with the addition of bacteria reached 82.2 mg/kg by the plant Tradescantia pallida, whereas the highest Cr uptake without bacterial addition was only 53.3 mg/kg by the same plant. A similar result was observed for the metal V, with the highest uptake under bacterial treatment reaching 63.8 mg/kg, compared to 54.6 mg/kg without bacterial addition by Tradescantia pallida. However, the addition of bacteria did not positively influence supporting parameters such as electrical conductivity and pH . The role of cow manure as a stimulant appeared more dominant than that of bacteria in affecting these parameters.
