Abstract

Aquatic plants are adaptive living on the gradient of acidity of peat waters in Palangka Raya city, with their potential role in remediating city wastewater. This research is aimed to study the ability of several aquatic plant species to remediate organic wastewater on a laboratory scale. The treatment was done from July to September 2020 in the field laboratory, greenhouse in Palangka Raya, Central Kalimantan. We compared the phytoremediation abilities of aquatic plant species, i.e. water hyacinth (Eichornia crassipes), pickerelweed (Monochoria vaginalis (Burm. F) Presi), water spinach (Ipomoea aquatica), water primrose (Ludwigia ascedences), water lettuce (Pistia stratiotes), giant Salvinia (Salvinia molesta), and hornwort (Ceratophyllum demersum) on the wastewater of African catfish (Clarias gariepinus) by measuring coverage as an indicator of their growth and absorption ability. Physicochemical parameters measured were water level, sunlight intensity, water temperature, electrical conductivity, potential oxidation-reduction, pH, dissolved oxygen, phosphate, nitrate, and ammonia. Results showed that of seven species tested for their phytoremediation abilities on wastewater, giant Salvinia was among the highest reducing total organic matter by about 95%. The highest coverage was water lettuce by 92%, followed by giant Salvinia (79%) and water hyacinth (78%). However, phosphate and ammonia had a negative value of the relative absorption for all aquatic plant species, suggesting a surplus in concentration during incubation. In this case, absorption for phosphate and ammonia is detected from a median of the lowest concentration on each species (n = 4). Water hyacinth and giant Salvinia were the highest absorbing for respectively phosphate and ammonia. Nitrate was absorbed by 100% of all species, except hornwort of 88%. The best absorption of nitrate was by water lettuce. So, it can be concluded that giant Salvinia is the best at absorbing organic waste, followed by water hyacinth; and the best growing by coverage is water lettuce.Keywords:PhytoremediationAquatic plantAfrican catfishWastewaterPeat water

Abstract

Sungai Kahayan terletak di Provinsi Kalimantan Tengah yang bermuara di Kabupaten Pulang Pisau. Sungai Kahayan merupakan urat nadi kehidupan bagi masyarakat melalui melalui ekosistem perairan dan hutan di sekitarnya. Penggunaan lahan di Kabupaten Pulang Pisau didominasi oleh kelapa sawit dan karet sebagai komoditas utama. Perkebunan kelapa sawit yang memiliki izin adalah seluas ± 138.076 Ha tersebar di 6 (enam) Kecamatan di Kabupaten Pulang Pisau. Sungai Kahayan menjadi salah satu media penerima air limbah dari pabrik kelapa sawit. Status mutu air Sungai Kahayan adalah tercemar ringan dengan parameter kritis adalah Biochemical Oxygen Demand (BOD). Perlu diketahui kontribusi beban pencemar dari air limbah pabrik kelapa sawit dan perkebunan kelapa sawit terhadap daya tampung beban pencemar Sungai Kahayan. Analisis beban pencemar maksimum air limbah kelapa sawit dilakukan menggunakan program pemodelan Qual2Kw. Sungai Kahayan mengalami pencemaran bahan organik yang ditandai dengan tingginya konsentrasi BOD, TSS, dan rendahnya kadar DO. Aktivitas industri kelapa sawit, baik dari limbah cair pabrik maupun limbah perkebunan, memberikan kontribusi signifikan terhadap pencemaran tersebut. Model Qual2Kw yang dikembangkan dalam penelitian ini dapat digunakan untuk mengevaluasi jumlah maksimum beban pencemar yang dapat diterima oleh Sungai Kahayan dan melakukan skenario penurunan beban pencemar. Berdasarkan validasi model, hasil simulasi menunjukkan kesesuaian dengan kondisi lapangan dengan tingkat kesalahan (RMSPE) sebesar 10%. Hasil simulasi menunjukkan bahwa daya tampung beban pencemar (DTBP) Sungai Kahayan untuk parameter BOD sudah terlampaui, sehingga tidak ada alokasi beban pencemar air limbah industri kelapa sawit yang boleh masuk ke sungai. Skenario penurunan beban pencemar melalui pengurangan konsentrasi dan debit air limbah pabrik kelapa sawit serta pembatasan pembukaan lahan perkebunan hanya dapat menurunkan beban pencemar hingga 38,46%, namun masih berada di atas baku mutu air kelas II.
