Abstract

Beberapa parameter air limbah domestik di IPAL Margasari Kota Balikpapan melebihi baku mutu, yaitu parameter amonia, Biological Oxygen Demand (BOD), dan Chemical oxygen Demand (COD). Salah satu opsi pengolahan secara biologi adalah menggunakan teknik fitoremediasi dengan menggunakan tanaman eceng gondok (Eichhornia crassipes). Penambahan aerasi dapat membantu mempercepat proses penyerapan polutan yang ada pada air limbah. Tujuan penelitian ini adalah untuk mengetahui efisiensi penyisihan dan menganalisis pengaruh variasi massa eceng gondok dan penambahan aerasi terhadap penurunan kadar amonia, BOD, dan COD pada Inlet IPAL Margasari. Penelitian ini menggunakan reaktor sistem batch dengan variasi massa tanaman eceng gondok 500 gram, 750 gram dan 1000 gram. Pengamatan dilakukan secara time series pada hari ke 3, 6, dan 9. Hasil penelitian menunjukkan waktu efektif tanaman eceng gondok dalam penyisihan kadar amonia, BOD, dan COD adalah 3 hari. Pada parameter amonia perlakuan tanpa aerasi 500 gram memiliki efisiensi yang paling tinggi yaitu 99,66% dan untuk parameter BOD dan COD pada perlakuan kombinasi antara fitoremediasi dan aerasi dengan massa 1000 gram dan 750 gram memiliki efisiensi yang paling tinggi yaitu 96,42% dan 85,92% dalam menurunkan kadar BOD dan COD pada air limbah domestik. Air limbah di IPAL Margasari bersifat biodegradable dengan nilai rasio BOD/COD 0,39-0,42.

Abstract

The wastewater generated from the tofu industry often contains elevated levels of COD and TSS pollutants. One effective method for treating this wastewater is through the coagulation-flocculation process. Moringa seeds, recognized as a biomass with natural coagulant properties, contain a bioactive compound known as 4αL-rhamnosyloxy-benzyl-isothiocyanate, capable of adsorbing particles present in wastewater. The objective of this study is to assess the efficiency of reducing pollutant parameters (COD, TSS, and Turbidity) in wastewater from the tofu industry by utilizing Moringa seeds as a natural coagulant. The research was conducted using a jar test apparatus with coagulation stirring at 100 rpm and flocculation at 40 rpm for 12 minutes. The study involved varying coagulant doses (2, 3, 4, 5, and 6 g/L of tofu wastewater) and coagulation stirring times (1, 3, and 5 minutes). Based on the results obtained, the optimal stirring duration and dose, as well as the efficiency of reducing each pollutant parameter, were determined. For COD, the optimal conditions were found to be 3 minutes stirring time with a dose of 4 g/L, resulting in an efficiency of 64.88%. Similarly, for TSS parameters, the optimum conditions were achieved with 3 minutes of stirring time and a dose of 4 g/L, yielding an efficiency of 52.71%. Lastly, for turbidity, the most effective conditions were observed with 3 minutes of stirring time and a dose of 4 g/L, with an efficiency of 58.85%.

Abstract

Balikpapan City is a city that does not have a large river to supply raw water like in several other cities, so to meet the water needs of the community, the main source of raw water is obtained from surface water from the Manggar Reservoir. The presence of high amounts of organic contaminants such as BOD and COD will affect water quality if treatment is not carried out to reduce these pollutants. One of the efforts that can be made to reduce pollutant levels is by the adsorption process using natural adsorbents, namely activated carbon from cassava peels. This research was conducted to find out how the effect of mass, contact time and the effectiveness of adsorbents from activated carbon of cassava peels in reducing BOD and COD levels in Manggar reservoir water, Balikpapan City. The adsorption process was carried out using variations in mass of 1, 3, 5, 7 and 9 gr and contact time variations of 30, 45, 60, 75 and 90 minutes. Based on the results of the study, the efficiency of reducing the BOD concentration of the adsorbent of activated carbon from cassava peels was 95.06% from the initial concentration of 8.3 mg/L to 0.41 mg/L at the optimum mass of 5 grams and the efficiency of reducing the COD concentration was 100% of the initial concentration of 28.54 mg/L to 0 mg/L at an optimum mass of 3 grams with a contact time of 30 minutes. From the results of the statistical analysis tests performed, it was found that the mass variation of the adsorbent did not significantly affect the decrease in BOD and COD concentrations, while the contact time had a significant effect only on the decrease in BOD concentrations.
