Abstract

The wastewater effluent of Ngabang Palm Oil Industry in one of several industrial waste, that contains high organic substances. One of them is nitrogen (N-total). Waste water treatment of palm oil industry used ponding system today, and one of solution to treat that wastewater effluent is using aquatic weeds as biofilter action. Water hyacinth (Eichornia crassipes (Mart.) Solms) and water fern (Salvinia molesta D.S.Mitchell) known as aquatic weeds that capable to decrease in a large amount the organic and inorganic substances. The aim of this research is to study the capacity of water hyacinth and water fern in decreasing nitrogen compounds (N-total, ammonia, nitrate, nitrite, N-organic) in wastewater effluent palm oil industry based in variation of treatment and difference of exposure time. This research was carried out in green house and Biology Laboratory of Biology Programme Study, Mathematic and Science Faculty of Tanjungpura University and Testing Laboratory of Institute for Industrial Research And Standardization Pontianak, from July 1st – October 31th, 2006. This experiment was designed in Completely Randomized Factorial Design with three treatments and three replication times. The collected data analized by Annava Test and least Significance Difference (LSD) test. The result show that the treatment with combination of water hyacinth and water fern were able to decrease the N-total (92,64%); ammonia (96,47%); and nitrite (90,14%).

Abstract

Air limbah industri harus diolah terlebih dahulu agar tidak mencemari badan air dimana limbah tersebut dibuang. Tujuan penelitian ini adalah mengetahui kemampuan lumpur aktif biakan campuran dari lumpur industri crumb rubber dalam menurunkan kadar COD, BOD dan TSS air limbah dan efsiensi penurunan COD, BOD dan TSS yang terjadi. Air limbah diperoleh dari PT. Star Rubber, Kubu Raya. Penelitian dilakukan dengan variabel yang telah ditentukan yaitu MLSS dan waktu. Metode penelitian meliputi melakukan pengaktifan lumpur, pencampuran lumpur aktif dengan air limbah dan pengujian. Hasil yang diperoleh yaitu efsiensi penurunan (% reduksi) COD berkisar antara 52-78,2% dan efsiensi penurunan BOD berkisar antara 19,5-86,75%. Penurunan COD dan BOD pada variabel waktu 4 jam lebih kecil daripada variabel waktu 2 jam. Penurunan COD dan BOD pada variabel MLSS 241.000 ppm cenderung lebih kecil daripada variabel MLSS 951 ppm. Untuk semua variabel, kadar TSS setelah proses berada di bawah batas maksimal baku mutu limbah cair untuk industri karet. Dilihat dari efsiensi penurunannya, system ini kurang efektif, perlu dilakukan penelitian lebih lanjut agar menemukan kondisi yang tepat sehingga lebih efektif.
