Studi Pengolahan Limbah Cair Domestik Dengan Biofilter Media Ijuk

Abstract

ABSTRAK
 Hotel di kawasan pariwisata merupakan salah satu sumber penghasil limbah cair domestik. Pengolahan limbah cair domestik dilakukan untuk mencegah terjadinya pencemaran lingkungan. Penelitian ini bertujuan untuk mengetahui efektivitas penggunaan ijuk sebagai media biofilter untuk mengolah limbah cair domestik dari hotel. Desain penelitian yang digunakan adalah kuasi eksperimental. Data yang digunakan pada penelitian ini adalah data primer dari hasil pengujian laboratorium. Pada penelitian ini parameter yang akan diteliti adalah BOD5, COD, TDS, dan pH. Berdasarkan sampel yang diambil di salah satu hotel di Kota Denpasar, nilai rata-rata parameternya antara lain: BOD5 sebesar 86,71 mg/L, COD sebesar 122,3 mg/L, TDS sebesar 529 mg/L, dan pH 8. Sebelum diuji dilakukan seeding selama 2 minggu untuk menumbuhkan bakteri di dalam reaktor. Efektivitas sistem yang diperoleh selama 5 minggu pengujian memiliki nilai rata-rata sebesar 33,05%, dengan persentase efektivitas penurunan parameter pencemar antara lain: BOD sebesar 46,47%, COD sebesar 39,88%, TDS sebesar 12,81%. Terdapat beberapa faktor yang mempengaruhi kinerja reaktor seperti: air limbah yang dipergunakan memiliki kualitas yang fluktuatif, cara penyusunan media biofilter, dan kondisi lingkungan saat penelitian dilakukan.

 ABSTRACT
 Hotels in tourism areas are a source of domestic wastewater. Domestic wastewater treatment is carried out to prevent environmental pollution. This study aims to determine the effectiveness of using palm fiber as a biofilter medium to treat domestic wastewater from hotels. The research design used was quasi experimental. The data used in this study are primary data from laboratory test results. In this study, the parameters to be studied are BOD2, COD, TDS, and pH. Based on samples taken at a hotel in Denpasar City, the average parameter values include: BOD5 of 86.71 mg/L, COD of 122.3 mg/L, TDS of 529 mg/L, and pH of 8. Before being tested, seeding was carried out for 2 weeks to grow bacteria in the reactor. The system effectiveness obtained during the 5 weeks of testing has an average value of 33.05%, with the percentage of effectiveness of decreasing pollutant parameters, among others: BOD of 46.47%, COD of 39.88%, TDS of 12.81%. There are several factors that affect the performance of the reactor, such as: the quality of the wastewater used is fluctuating, the way the biofilter media is prepared, and the environmental conditions when the research is carried out.

Rekayasa Pengolahan Air Limbah Domestik Dengan Metode Kombinasi Filtrasi Untuk Menurunkan Tingkat Polutan Air

“…Berdasarkan tabel 3 diatas, dapat diketahui tabel konsentrasi TSS menurun seiring dengan dialirkan air limbah tersebut secara kontinu dari wadah 1 hingga wadah 3 dengan variasi media filter yang berbeda. Konsentrasi TSS awal terukur 225 mg/L, pada wadah 2 dan 3 konsentrasi TSS tersisih hingga 0,8% pada limbah cair domestik 17 .…”

“…Ijuk tahan terhadap asam dan garam yang terdapat dalam air asin dan memiliki ketahanan yang baik serta umur yang panjang. 17 . Ijuk dan kerikil berfungsi sebagai media penyaring polutan halus.…”

Physical Condition of Filtrated Wastewater from Bakery Household Business

“…Palm fiber is a material commonly used for filtration, because it is a fiber resistant to acids and salts, also known as strong resistance [9], so it is considered to have a good ability to be used in water treatment processes. Furthermore, the result of a study about domestic wastewater from hotel activities that were processed using palm fiber as biofilter media shows that although it was said to be ineffective weekly, the result of filtration showed that the value of the contaminant parameter had decreased [10] mainly for odor [11]. Based on the studies conducted, it can be observed that the palm fiber used as filter media must be ensured to be clean and not too dry (washed first) so that the dust on the palm fiber is not carried away during the filtration process and affects the color of the processed wastewater.…”
