Abstract
Maraknya kegiatan laundry meningkatkan penggunaan deterjen sebagai bahan utama dalam pembersihan. Air buangan hasil kegiatan laundry yang langsung dibuang ke badan air akan mengganggu keseimbangan ekosistem badan air. Hal ini dikarenakan air limbah laundry mengandung surfaktan yang tinggi dan dapat menimbulkan eutrofikasi. Tujuan penelitian ini adalah menentukan komposisi kapur-semen untuk media artifisial pada pengurangan surfaktan air limbah laundry, mengkaji efektivitas batu kapur (CaCO3) sebagai media pengikat surfaktan, dan mengkaji media kapur-semen dan batu kapur untuk menurunkan surfaktan pada air limbah laundry
Sampel air laundry diambil dari satu usaha laundry yang berada di Keputih. Sampel diambil pada masing-masing proses pencucian mulai dari pemberian deterjen hingga pembilasan akhir. Penelitian diawali dengan karakterisasi limbah laundry. Parameter analisis untuk karakterisasi limbah laundry adalah surfaktan dengan melakukan uji MBAS (Methylene Blue Active Substance). Penelitian skala laboratorium yang dilakukan adalah pembuatan media kapur-semen dengan rasio (1:1, 2:1 , 3:1 , 4:1 , 5:1 , 6:1) kapur yang digunakan adalah (CaO) berbentuk powder. Media yang telah dibuat, akan diuji secara batch kemudian filtrat akan diuji nilai MBAS. Hasil dari penelitian pendahuluan ini adalah untuk mendapat rasio media kapur-semen yang optimum untuk media yang akan dilakukan pada penelitian utama. Operasi media dilakukan secara continuous dengan variasi jenis media yang digunakan serta debit yang masuk. Proses operasi dengan menggunakan tiga jenis media yaitu kapur-semen yang terpilih dari hasil penelitian pendahuluan serta media batu kapur (CaCO3) dan tutup botol sebagai variabel kontrol.
Hasil karakterisasi awal limbah laundry kandungan surfaktan sebesar 199,62 mg/L, COD 1600 mg/L, TSS 220 mg/L, pH 7,08. Berdasarkan pada penelitian dengan proses batch diperoleh rasio kapur-semen terbaik yaitu 6:1. Pengambilan effluent setelah pengendapan. Media kapur-semen mampu mereduksi surfaktan sebesar 80% dengan pengoperasian selama 6 jam, 97% dengan waktu tinggal 7 dan 8 jam. Media batu kapur mampu mereduksi surfaktan sebesar 30% dengan waktu tinggal 6 jam, 43% dengan waktu tinggal 7 jam, dan 50% dengan pengoperasian selama 8 jam.

Due to high demand in the laundry business, the use of detergent as a main material in cleaning process is increasing. If the effluent of the laundry process is directly discharged to the water body, it will interupt the ecosystem in the water body. Therefore, laundry wastewater containing surfactants in high concentration will cause eutrofication. This research is aimed to determine the composition of lime-cement as artificial media to reduce surfactant from laundry wastewater, evaluate the effectiveness of limestone (CaCO3) as a surfactant binder media, and evaluate lime-cement and limestone media to reduce surfactant from laundry wastewater.
The laundry wastewater samples were taken from one of the laundry businesses in Keputih. Samples were taken from each process of washing from input of detergent to final rinse. This research started with the characterization of laundry wastewater. The parameter needed to be analized is surfactant as MBAS (Methylen Blue Active Substance). Laboratory-scale part of the research is making lime-cement media with several ratios (1:1, 2:1, 3:1, 4:1, 5:1, 6:1). Lime used is calcium Oxide (CaO) in powder form. Media that has been made, will be tested in a batch system and its filtrate analysed using MBAS parameter. The result of the preliminary research is to get the optimum ratio of lime-cement media to reduce surfactant and will be used in the primary research. Operation of the primary research was conducted in a continuous system with some variations in media and the inflow discharge. The operation process using three kinds of media, which are lime cement media, lime stone (CaCO3), and plastic bottle cap as a control variable.
The result of the first characterization of laundry wastewater is 199,62 mg/L of surfactant, 1600 mg/L of COD, 220 mg/L of TSS and pH 7,08. Based on the preliminary research in batch system, lime-cement with 6:1 ratio was chosen as the optimum ratio. Effluent was taken after the settling process. The result of primary research is that lime-cement media could reduce surfactant up to 80% with time detention of 6 hours, 97% with time detention of 7 and 8 hours. Limestone media reduced surfactant up to 30% when time detention is 6 hours, 43% when time detention is 7 hours, and 50% when time detention is 8 hours.
