Nur’aini, Ashri (2019) Fitoremediasi Tanah Tercemar Logam Berat Kromium (Cr) Oleh Tanaman Akar Wangi (Vetiveria Zizanioides). Sarjana thesis, Universitas Brawijaya.
Abstract
Salah satu zat pencemar yang berbahaya untuk lingkungan adalah logam Kromium. Logam Kromium dapat dihasilkan dari industri tekstil, industri penyamakan kulit, pelapisan baja, dan lainnya. Pembuangan limbah industri yang mengandung logam berat Kromium ke perairan akan meningkatkan konsentrasi Kromium dalam perairan dan dapat mencemari air tanah. Penelitian yang dilakukan Komarawidjaja (2017) menunjukan hasil analisa tanah dari lahan persawahan di Jelegong, Kecamatan Rancaekek, Kabupaten Bandung tercemar logam berat akibat adanya limbah industri tekstil. Kandungan logam berat yang tinggi tersebut yaitu Cr (0,06-174,7 mg/l), As (0,28-4,0 mg/l) dan Hg (25,9 – 92,2 mg/l), sementara konsentrasi logam berat yang lain, Pb (0,05 – 11,7 mg/l), Cd (0,02 – 0,17 mg/l). Penelitian ini dilakukan dalam skala laboratorium dengan menggunakan tanaman akar wangi (Vetiveria zizanioides) terhadap tanah tercemar logam Cr 50 ppm, 100 ppm, dan 200 ppm, dengan 3 kali pengulangan pada masing-masing perlakuan. Parameter yang diamati selama penelitian meliputi tinggi tanaman, jumlah daun, suhu media tanam, dan suhu ruang. Hasil penelitian menunjukan pemberian variasi perlakuan logam berat tidak berpengaruh pada tinggi tanam tetapi berpengaruh pada jumlah daun minggu keenam hingga kedelapan, biomassa, dan luas daun. Konsentrasi Cr pada media tanam perlakuan 0 ppm memiliki hasil terkecil dibandingkan tiga perlakuan lain. Hasil konsentrasi Cr tertinggi media tanam ada pada perlakuan Cr 200 ppm dengan nilai 19,23 mg/kg. Total konsentrai Cr pada tanaman terbesar ada pada perlakuan 200 ppm yaitu 4,19 mg/kg.x Didapatkan hasil BCF logam Cr tanaman akar wangi adalah < 1 yaitu 0,03- 0,012. Logam Cr lebih banyak di jaringan akar dan hanya sedikit yang di translokasikan ke pucuk (TF<1).
English Abstract
One of the pollutants that are harmful to the environment is chromium metal. Chromium metal can be produced from the textile industry, leather tanning industry, steel coating, and others. Disposal of industrial waste containing heavy metal chromium into the waters will increase the concentration of chromium in the waters and can contaminate ground water. Research conducted by Komarawidjaja (2017) shows the results of soil analysis of paddy fields in Jelegong, Rancaekek District, Bandung Regency contaminated by heavy metals due to textile industry waste. The high content of heavy metals is Cr (0.06-174.7 mg / l), As (0.28- 4.0 mg / l) and Hg (25.9 - 92.2 mg / l), while other heavy metal concentrations, Pb (0.05 - 11.7 mg / l), Cd (0.02 - 0.17 mg / l). This study was done in laboratory scale using Vetiveria zizanioides with concentration of Cr polluted soil 50 ppm, 100 ppm, 200 ppm,, with three repetitions in each treatment. Parameters observed during the study included plant height, number of leaves, temperature of media, and room temperature. The results showed that the variation in treatment of heavy metals did not affect the height of the plant but it affected the number of leaves of the sixth to eighth week, biomass, and leaf area. Cr concentration in the growing media with 0 ppm treatment had the smallest results than the other three treatments. The highest concentration was found in the 200 ppm Cr which is 19.23 mg / kg. The largest total Cr concentration in the plant is in the treatment of 200 ppm which is 4.19 mg / kg. The results showed that the BCF of Cr in vetiver plants was <1, range between 0.03- 0.012. Chromium metal is mostly found in root tissue and only a few are translocated to the shoots (TF <1).
