Basith, Luthfi Abdul (2018) Pengaruh Massa Tanaman Bambu Air (Equisetum Hyemale) terhadap Penurunan Kadar Zn pada Limbah Cair Batik Menggunakan Zeolit dan Aerasi. Sarjana thesis, Universitas Brawijaya.
Abstract
Pewarnaan dalam proses membatik menghasilkan estetika yang indah pada kain, tetapi proses pewarnaan hanya menggunakan zat pewarna sekitar 5% dan sisanya akan dibuang sebagai limbah. Limbah cair sisa pewarnaan merupakan senyawa yang sulit untuk terdegradasi dan berbahaya bagi lingkungan. Hasil akhir proses pewarnaan pada limbah cair mengandung logam berat seperti logam Seng (Zn), Krom (Cr) dan dapat menaikan konsentrasi organik seperti BOD, COD, dan pH. Masuknya zat-zat kimia tersebut ke lingkungan secara langsung akan menyebabkan turunnya kualitas air serta gangguan organisme perairan dan manusia. Sehingga perlu adanya pengolahan limbah cair batik sebelum langsung dibuang ke lingkungan. Fitoremediasi menggunakan tanaman bambu air dan ditambah zeolit sebagai media tanam dan aerasi menjadi salah satu inovasi untuk pengolahan limbah cair batik. Penelitian ini bertujuan untuk mengetahui efektifitas massa tanaman bambu air (Equisetum Hyemale) terhadap mengurangi kadar Zn pada limbah cair batik. Penelitian dilakukan pada bulan Maret hingga April 2018 di Laboratorium Remediasi Fakultas Teknologi Pertanian, Universitas Brawijaya, Malang. Rancangan Percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 3 perlakuan. Perlakuannya adalah Tanpa Tanaman (M0), dengan Massa Tanaman 300 g (M300), dan dengan Massa Tanaman 450 g (M450). Penelitian dilakukan selama 12 hari dengan pengamatan pengukuran pH, suhu media tanam dan suhu lingkungan yang dilakukan setiap hari. Pengambilan sampel limbah cair dilakuan pada awal sampel dan hari ke-12, sedangkan sampel tanaman pada hari ke-12. Pengujian sampel limbah cair meliputi kadar logam Zn dan BOD. Sampel tanaman diuji kadar logam Zn, berat basah dan ix berat keringnya. Suhu lingkungan dan media tanaman memiliki ratarata sebesar 29oC dan 27oC. pH akhir limbah cair batik untuk perlakuan M0 sebesar 7,8 M300 sebesar 8,3 dan M450 sebesar 8,6. Penurunan BOD terbesar pada perlakuan M300 sebesar 23%, sedangkan M450 dan M0 sebesar 18% dan 12% dibandingkan dengan air limbah Pre-Treatment. .Efisiensi penurunan Zn terbesar pada perlakuan M450 sebesar 98%, sedangkan M300 dan M0 sebesar 96% dan 18% dibandingkan terhadap air limbah Pre- Treatment. Konsentrasi logam Zn terbesar pada tanaman bambu air terdapat pada bagian akar tanaman. Hasil perhitungannya adalah BCF>1 dan TF<1, sehingga tanaman bambu air dapat dikategorikan termasuk mekanisme fitostabilisasi. Perlakuan paling efektif dalam menurunkan Zn dan BOD adalah M300. Perlakuan M300 dapat menurunkan konsentrasi BOD tertinggi, selain itu dalam perhitungan statistic, BCF dan konsentrasi Zn tanaman memiliki hasil yang tidak signifikan dengan perlakuan M450.
English Abstract
Coloring in the batik process results a beautiful aesthetics on the fabric, but the coloring process uses only 5% of the dye and the rest will be discarded as waste. The residual liquid waste is a compound that is difficult to degrade and harmful to the environment. The final result of the coloring process on liquid waste contains heavy metals such as metal zinc (Zn), chromium (Cr) and it can also increase organic concentrations such as BOD, COD, and pH. The entry of these chemicals into the environment directly will cause a decrease in water quality and disruption of aquatic organisms and humans. So it is necessary to process batik liquid waste before being immediately discharged into the environment. Phytoremediation uses bamboo water plants and zeolite as a planting medium and aeration is one of the innovations for the processing of batik liquid waste. This study aims to determine the effectiveness of the bamboo water plant mass (Equisetum Hyemale) to reduce the level of Zn in batik liquid waste. The study was conducted in March to April 2018 at the Remediation Laboratory of the Faculty of Agricultural Technology, Brawijaya University, Malang. The experimental design used was a completely randomized design (CRD) with 3 treatments. The treatments were without plants (M0), with plant mass 300 g (M300), and with plant mass 450 g (M450). The study was conducted for 12 days by observing the measurement of pH, planting media temperature and environmental temperature carried out every day. The waste sample is taken at the beginning of the sampling and at the 12th day, while the plant sample is taken only at the 12th day. Testing of liquid waste samples includes Zn and BOD. Plant samples were tested for its Zn metal content, gross weight and dry weight. Environmental and plant media temperature have an average of 29oC and 27oC. The final pH of batik liquid waste for M0 treatment is 7.8 M300 of 8.3 and M450 of 8.6. The biggest BOD reduction in M300 treatment was 23%, while M450 and M0 were 18% and 12% compared to pre-treatment wastewater. The biggest Zn reduction efficiency in M450 treatment was 98%, while M300 and M0 were 96% and 18% compared to pre-treatment wastewater. The largest concentration of Zn metal in bamboo water plant was found in the roots of plants. The calculation results are BCF> 1 and TF <1, so that bamboo water plants xi can be categorized including phytostabilization mechanisms. The most effective treatment in reducing Zn and BOD is M300. The M300 treatment can reduce the highest BOD concentration, in addition, In addition, in statistical calculations, BCF and Zn concentrations of plants had insignificant results with M450 treatment.
