BIOSORPSI LOGAM BERAT (FE) PADA AIR KOLONG PASCA TAMBANG TIMAH DI PADANG BARU BANGKA OLEH Saccharomyces cerevisiae DENGAN PENGARUH VARIASI PH

Rahmah, Nurul Amira - Personal Name;

Aktivitas pertambangan timah di pulau Bangka telah lama berlangsung dan menjadi masalah utama karena menyebabkan terbentuknya kolong atau lubang-lubang besar dan merusak sifat kimia tanah berupa tingginya kandungan logam. Tingginya kadar logam perlu dinetralisir agar tidak mengganggu ekosistem, salah satunya logam berat besi (Fe). Logam berat besi (Fe) akan berbahaya jika terkonsumsi di atas jumlah normal yang mengakibatkan kerusakan hati dan ginjal. Biosorpsi dikenal sebagai salah satu teknologi yang dapat mengolah logam berat menggunakan mikroorganisme yang hidup ataupun mati. pH menjadi salah satu faktor dalam proses biosorpsi yang mempengaruhi kelarutan logam. Salah satu mikroorganisme yang dapat digunakan sebagai biosorben yakni Saccharomyces cerevisiae. Penggunakan biomassa mati Saccharomyces cerevisiae memiliki kelebihan tidak memerlukan penambahan nutrisi dalam penyerapannya. Penelitian ini bertujuan mengetahui berapa besar kemampuan biomassa mati Saccharomyces cerevisiae dan mengetahui pengaruh variasi berbagai pH terhadap biosorpsi logam berat besi (Fe). Penelitian ini menggunakan variasi pH 3, 4, 5, 6, dan 7 dengan berat biosorben 0,1 g/L. Kemampuan biomassa Saccharomyces cerevisiae dalam mengabsorpsi logam berat besi (Fe) secara optimum diperoloeh pada pH 5 dengan persentase serapan 94,47% dengan penurunan kadar logam hingga 0,795 mg/L. Kata kunci : Aktivitas Pertambangan, Logam Besi (Fe), Biosorpsi, pH, Saccharomyces cerevisiae. Tin mining activities on Bangka Island have been going on for a long time and have become a major problem because they cause the formation of large pits and damage the chemical properties of the soil in the form of high metal content. High levels of metals need to be neutralized so as not to disturb the ecosystem, one of which is heavy metal iron (Fe). Heavy metal iron (Fe) will be dangerous if consumed above normal amounts resulting in liver and kidney damage. Biosorption is known as one of the technologies that can treat heavy metals using living or dead microorganisms. pH is one of the factors in the biosorption process that affects metal solubility. One of the microorganisms that can be used as a biosorbent is Saccharomyces cerevisiae. The use of Saccharomyces cerevisiae dead biomass has the advantage of not requiring the addition of nutrients in its absorption. This study aims to determine how much the ability of Saccharomyces cerevisiae dead biomass and determine the effect of various pH variations on the biosorption of heavy metal iron (Fe). This study used pH variations of 3, 4, 5, 6, and 7 with biosorbent weight of 0.1 g/L. The ability of Saccharomyces cerevisiae biomass in absorbing iron (Fe) heavy metal was optimally obtained at pH 5 with a percentage of uptake of 94.47% with a decrease in metal levels up to 0.795 mg/L. Keywords: Mining Activity, Iron Metal (Fe), Biosorption, pH, Saccharomyces cerevisiae.
