Abstract
Pengolahan air limbah dengan menggunakan tumbuhan air atau phytotreatment telah menjadi salah satu alternatif pengolahan air limbah yang cukup murah dan efisien dalam penerapannya. Pada industri tekstil, zat warna ini terdiri dari berbagai macam polutan dari proses yang berbeda-beda. Tumbuhan air lebih efektif dalam pengolahan air limbah dibandingkan dengan tanaman lainnya karena pertumbuhan mereka lebih cepat dan produksi biomassa yang lebih besar. Kemampuannya relatif lebih tinggi untuk meyerap polutan karena kontak langsung dengan air yang terkontaminasi.
Dalam Tugas Akhir ini, dilakukan penelitian untuk membandingkan efisiensi tumbuhan air yaitu Eceng gondok (Eichhornia crassipes) dan Kayu apu (Pistia stratiotes) dalam dekonsentrasi warna. Kedua tumbuhan ini dapat hidup di lingkungan tercemar dan cocok dimanfaatkan untuk pengolahan limbah. Selain itu, kedua jenis tumbuhan ini merupakan jenis tumbuhan semi aquatic yang bisa hidup di lahan basah ataupun kering. Variabel yang digunakan yaitu dua jenis tumbuhan air (E.crassipes dan P. stratiotes) dan tiga jenis pewarna (rhodamin B, metilene biru dan metil violet). Dilakukan tahapan yaitu propagasi tumbuhan, tahap aklimatisasi, tahap range finding test dan uji phytotreatment selama 30 hari dengan parameter utama uji warna dan parameter pendukung yaitu uji suhu, pH, analisa morfologi, berat basah dan berat kering. Dilakukan juga uji toksisitas pada LC-50 dan uji plant cells analysis.
Hasil penelitian menunjukkan bahwa uji toksisitas LC-50 dari ketiga warna tersebut, bahwa tumbuhan eceng gondok memiliki ketahanan respons biologis yang lebih besar bila dibandingkan dengan tumbuhan P. stratiotes. Nilai LC-50 tumbuhan E. crassipes terhadap pewarna rhodamin B sebesar 99,5 mg/L dan P.stratiotes sebesar 42,9 mg/L. Nilai LC-50 tumbuhan E. crassipes terhadap pewarna metilen biru sebesar 74,5 mg/L dan tumbuhan P.stratiotes sebesar 54,7 mg/L. Nilai LC-50 tumbuhan E.crassipes terhadap pewarna metil violet sebesar 83,2 mg/L dan LC-50 P.stratiotes adalah 70,04 mg/L.
Hasil penyisihan warna pada hari ke 30 oleh tumbuhan E.crassipes terhadap warna metilen biru mencapai 59% sedangkan pada kontrol mencapai 59%, warna rhodamin B mencapai 52% dan pada kontrol mencapai 52% dan metil violet sebesar 51% sedangkan pada kontrol mencapai 51%. Pada tumbuhan P. stratiotes terhadap warna metilen biru mencapai 74% dan pada kontrol mencapai 75%, warna rhodamin B mencapai 78% sedangkan pada kontrol mencapai 78% dan metil violet mencapai 55% dan pada kontrol mencapai 55%. Berdasarkan hasil persentase penyisihan warna yang dihasilkan maka dapat disimpulkan bahwa penyisihan warna rhodamin B, metilen biru dan metil violet oleh tumbuhan E.crassipes dan P. stratiotes sampai 30 hari pemaparan kurang efektif karena mikroorganime indigenous yang lebih berperan.
=================================================================
The costing of wastewater treatment such as dye wastewater in developing countries are expensive. The dye has a variety of pollutants in different processes. Wastewater treatment using aquatic plants has become one of alternative wastewater treatment that is reasonably priced and efficient in its application. Water plants were more effective in wastewater treatment as compared to other crops because of their faster growth and greater biomass production. The ability was relatively higher than the absorption of pollutants because, aquatic plants contact with contaminated water directly.
The aims of this study was to compare the efficiency of aquatic plants such as Eichhornia crassipes and Pistia stratiotes for treatment of rhodamine B, methylene blue and methylene violet. There were three research phases, namely the propagation of plants to increase plant and determine the growth of plant. The second phase was plants acclimatization which conducted for 3 days for conditioning plant reactor water with plastic tubs media in order to adapt to a new habitat. After a period of acclimatization was complete, then the plants were ready to be used in research. Range finding test was carried out for 14 days to determine the ability of those plants in hodamine B, methylene blue and methyl violet. And the lastest test, phytotreatment was conducted for 28 days of exposure.Some parameter that measured were colour, temperature and pH.
The results showed that the LC-50 toxicity test of the three colors, that hyacinth plants have greater biological response resistance when compared with P.stratiotes plants. The LC-50 values of E. crassipes and P.stratiotes plants to rhodamine B dye amounted (99.5 mg/L) and P.stratiotes amounted (42.9 mg/L). The LC-50 values of E. crassipes and P.stratiotes plants to blue methylene dye amounted to 74.5 mg/L and P.stratiotes plant amounted (54.7 mg/L). LC-50 values of E. crassipes and P.stratiotes plants to blue methylene dye amounted (83.2 mg/L) and LC-50 P.stratiotes amounted (70.04 mg/L).
The result of color removal on day 30 for the E.crassipes plant to the color of methylene blue reached 59% while the control reach 59%, rhodamin B color reach 52% and the control reached 52% and metil violet reached 51% while the control reach 51% . In the P. stratiotes plant to the color of methylene blue reached 74% and the control reached 75%, rhodamin B color reached 78% while the control reached 78% and methyl violet reached 55% and the control reached 55%. Based on the result of color removal percentage, it can be concluded that the color removal of rhodamine B, methylene blue and methyl violet by E.crassipes and P. stratiotes plants until 30 days the exposure is less effective because indigenous microorganism which takes the big part.
