Abstract

Data dari Kementerian Perindustrian pada 2020 menunjukkan bahwa terdapat sekitar 4.996 unit usaha batik di Indonesia, dengan sekitar 3.000 unit berlokasi di Jawa Tengah dan DIY. Limbah cair yang dihasilkan oleh industri batik mencapai 150.000 m3 setiap tahunnya. Jika limbah cair dari industri batik tidak dikelola dengan tepat dan memadai, maka dapat menimbulkan masalah lingkungan yang mengkhawatirkan, terutama pada ekosistem air. Diperlukan pengolahan yang dapat diaplikasikan guna memperbaiki ekosistem air yang tercemar limbah industri batik. Salah satu cara yang dapat dilakukan adalah menggunakan fitoremediasi. Penelitian kali ini bertujuan untuk mengetahui kemampuan tumbuhan Neomarica gracilis dan Echinodorus palaefolius dalam meremediasi air tercemar limbah industri batik menggunakan metode floating wetland. Penelitian dilakukan dalam skala laboratorium dengan sistem batch reaktor. Uji pendahuluan berupa propagasi dilakukan guna menentukan umur optimum tumbuhan yang nantinya digunakan dalam fitoproses dengan hasil Neomarica gracilis berumur 5 minggu dan Echinodorus palaefolius berumur 5 minggu. Setelah itu dilakukan range finding test dengan varian konsentrasi uji sebesar 0%, 2%, 4%, 6%, 8%, dan 10%. Konsentrasi 8% air limbah batik digunakan dalam fitoproses karena memberikan efek kepada tumbuhan uji. Fitoproses dilaksanakan selama 7 hari dengan uji parameter BOD, COD, Amonia, DO, pH, dan suhu dilakukan setiap hari. Setelah dilakukan uji fitoproses selama 7 hari, tumbuhan Neomarica gracilis mampu melakukan penyisihan polutan secara optimum dengan metode free surface water flow yakni BOD sebesar 83,6% atau 76,1 mg/L, kandungan COD sebesar 84,7% atau 367 mg/L, dan amonia sebesar 59,6% atau 6,43 mg/L. Sedangkan tumbuhan Echinodorus palaefolius dengan metode yang sama yakni free surface water flow mampu menyisihkan kandungan BOD sebesar 75,7% atau 68,88 mg/L, kandungan COD sebesar 77,3% atau 334,94 mg/L, dan amonia sebesar 58,2% atau 6,28 mg/L. Dengan metode free surface water flow, Neomarica gracilis lebih efektif untuk melakukan penyisihan polutan sedangkan jika menggunakan metode floating wetland, Echinodorus palaefolius lebih efektif untuk melakukan penyisihan polutan.

Data from the Indonesian Ministry of Industry in 2020 showed that there are around 4,996 batik businesses in Indonesia, with around 3,000 of them located in Central Java and the Special Region of Yogyakarta. The batik industry produces around 150.000 m3 of liquid waste every year. If this waste is not managed properly, it can cause serious environmental problems, especially for aquatic ecosystems. One way to treat this waste is through phytoremediation, which uses plants to absorb and break down pollutants. This study investigated the ability of two plants, Neomarica gracilis and Echinodorus palaefolius, to remediate water polluted by batik industry waste using a floating wetland system. The research was conducted in a laboratory scale with a batch reactor system. A preliminary test in the form of propagation was carried out to determine the optimum age of the plants that would later be used in phytoremediation, with the results of Neomarica gracilis aged 5 weeks and Echinodorus palaefolius aged 5 weeks. After that, a range finding test was carried out with a test concentration variance of 0%, 2%, 4%, 6%, 8%, and 10%. A concentration of 8% batik wastewater was used in phytoremediation because it had an effect on the test plants. Phytoremediation was carried out for 7 days with tests of BOD, COD, ammonia, DO, pH, and temperature performed every day. After a phytoremediation test, Neomarica gracilis plants were able to optimally remove pollutants using the free surface water flow method, with BOD of 83,6% or 76,1 mg/L, COD of 84,7% or 367 mg/L, and ammonia of 59,6% or 6,43 mg/L. Echinodorus palaefolius plants using the same method, free surface water flow, were able to remove BOD of 75,7% or 68,88 mg/L, COD of 77,3% or 334,94 mg/L, and ammonia of 58,2% or 6,28 mg/L. With the free surface water flow method, Neomarica gracilis is more effective for pollutant removal, while if using the floating wetland method, Echinodorus palaefolius is more effective for pollutant removal.
