Abstract

The Citarum River was regarded as the World’s dirtiest river in 2018, characterized by a Basin situated adjacent to several textile and electroplating industries. Hexavalent chromium metal (Cr6+) is a toxic, carcinogenic heavy metal found in the wastes of these industries. Furthermore, biosorption with biological adsorbents, including Saccharomyces cerevisiae and Rhizopus oryzae, is an alternative method for treating water polluted with heavy metals. This study therefore aims to adsorb Cr6 + heavy metals from Citarum River water using S. cerevisiae and R. oryzae biomass in two locations: Nanjung and Pangauban, with various biomass concentration and stirring speeds. For this study, 0.25, 0.5, and 0.75 g of R. oryzae suspension, as well as 250, 500, and 750 µ of S. cerevisiae were used as adsorbent, while rotated at speeds of 250 rpm, 750 rpm and 1500 rpm. Subsequently, the Cr6 + metal content was measured using a UV-Vis spectrophotometer at a wavelength of 525 nm, and calculated based on a standard curve. The results showed S. cerevisiae and R. oryzae are able to reduce the levels of Cr6+ in Citarum river water. The most reduction was obtained with the highest concentration of the adsorbents, 750 µ for S. cerevisiae and 0.75 g for R. oryzae, at the speed of 1500 rpm. S. cerevisiae and R. oryzae have great potential as biosorbents for the in situ remediation of Citarum River contaminated with heavy metals.

Abstract

Pencemaran sungai Citarum diakibatkan oleh limbah industri yang dibuang langsung ke sungai. Salah satu komponen limbah cair yang sering ditemui dan bersifat sangat toksik yaitu logam berat kromium(VI). Penelitian ini bertujuan untuk mengetahui perbedaan kadar Cr(VI) dalam sampel air Sungai Citarum sebelum dan setelah dilakukan proses biosorpsi dengan menggunakan jumlah biosorben optimum sekam padi yang tidak diarangkan. Proses biosorpsi dilakukan dengan mengontakkan sampel air Sungai Citarum dengan biosorben sekam padi pada variasi berat sebesar 0,1; 0,5; 1,0; 1,5, dan 2,0 g. Hasil pengujian menunjukkan adanya penurunan kadar Cr(VI) setelah biosorpsi menggunakan biosorben sekam padi. Persentase penurunan kadar logam Cr(VI) tertinggi terjadi pada seluruh titik sungai dengan penambahan biosorben sekam padi sebanyak 1,5 g yaitu berturut-turu sebesar 41,18%; 62,65%; 55,07%; dan 56,43%. Pada penambahan jumlah biosorben sebanyak 2g mengalami penurunan kapasitas biosorpsi karena terjadi gangguan pembentukan logam-biosorben akibat adanya interfensi antar situs. Dari penelitian ini, dapat disimpulkan bahwa kapasitas biosorpsi meningkat sebanding dengan penambahan jumlah biosorben sekam padi dan optimum pada penambahan jumlah biosorben sekam padi sebanyak 1,5 g.UTILIZATION OF RICE HUSKS FOR BIOSORPTION PROCESS OF Cr(VI)IN CITARUM RIVER WATER SAMPLESThe Citarum River, as the river with the highest pollution level in Indonesia, certainly needs to be addressed immediately. The pollution is caused by industries which dump their waste directly into rivers. One of the components of liquid waste that is often encountered and is highly toxic is the heavy metal chromium(VI). This study aimed to determine the Cr(VI) levels in Citarum River water samples before and after the biosorption process using the optimum biosorbent of uncharred rice husks. The method used in this research is descriptive quantitative. The biosorption process was carried out by contacting Citarum River water samples with rice husk biosorbents at various amounts of 0.1 g; 0.5; 1.0; 1.5, and 2.0 g. The test results show a decrease in Cr(VI) levels after biosorption using rice husk biosorbent. The highest percentage decrease in Cr(VI) metal content occurred at all points of the river with 1.5 g of rice husk biosorbent, namely 41.18% respectively; 62.65%; 55.07%; and 56.43%. With the addition of 2g of biosorbent, the biosorption capacity decreased. There is interference with the formation of metal-biosorbent due to interference between sites. From this research, it can be concluded that the biosorption capacity increases with the addition of the rice husk biosorbent and the optimum with 1.5 g of rice husk biosorbent.
