Abstract
Pengolahan lumpur yang dihasilkan oleh industri pengolahan air penting dilakukan karena berpotensi mengandung bahan-bahan yang dapat membahayakan lingkungan. Beberapa penelitian menunjukkan adanya kandungan bahan pencemar yang terdapat pada lumpur yang dihasilkan oleh PDAM, yaitu mikroplastik, aluminium sulfat, serta COD. Oleh karena itu, teknologi Stabilisasi/Solidifikasi (S/S) dapat dipertimbangkan sebagai teknik pengolahan lumpur PDAM. Studi literatur ini bertujuan untuk menentukan karakteristik lumpur ditinjau dari mikroplastik dan bahan pencemar lainnya, aplikasi teknologi S/S untuk pengolahan lumpur, serta menentukan kelayakan hasil S/S untuk bahan konstruksi.
Metoda studi yang digunakan yaitu pencarian sumber literatur terkait pembahasan studi. Sumber studi literatur ini adalah jurnal ilmiah, tugas akhir, tesis, disertasi, dan literatur lain yang berhubungan dengan ide studi. Data yang dibutuhkan meliputi data kandungan lumpur PDAM, sumber bahan pencemar yang terdapat pada lumpur PDAM, penelitian terdahulu mengenai pengolahan limbah dengan metode S/S, hasil pengujian mutu terhadap produk S/S, serta baku mutu bahan konstruksi. Data tersebut dianalisis untuk menentukan kelayakan aplikasi S/S lumpur PDAM untuk dijadikan sebagai bahan konstruksi yang memenuhi baku mutu.
Teknik S/S mampu mengikat bahan pencemar pada lumpur PDAM sekaligus produknya dapat dimanfaatkan untuk bahan konstruksi. Karakteristik lumpur dapat mempengaruhi komposisi bahan S/S. Teknik S/S untuk batu bata dilakukan tanpa proses pembakaran dengan komposisi 33,33% cake lumpur PDAM, 33,33% semen, dan 33,33% pasir (1:1:1). Produk yang dihasilkan memiliki nilai kuat tekan sebesar 7 MPa yang bisa dimanfaatkan sebagai bahan konstruksi dinding. Sedangkan untuk paving block menggunakan komposisi 25% semen, 22,5% lumpur, dan 52,5% pasir. Namun, komposisi tersebut dapat diterapkan apabila kandungan Al <20% komposisi total, dan mikroplastik <0,42% komposisi total. Hasil uji TCLP campuran sebesar <0,03 mg/L, yang berarti masih memenuhi baku mutu. Produk tersebut memiliki nilai kuat tekan sebesar 12,4 MPa, yang memenuhi minimal mutu kelas C dan dapat dimanfaatkan sebagai bahan konstruksi fasilitas untuk pejalan kaki.

Treatment process of sludge by the water treatment industry is important because it has the potential to contain materials that can harm the environment. Several studies have shown that there are pollutants in the sludge produced by WTP, such as microplastics, aluminum sulfate, and COD. Therefore, stabilization/solidification (S/S) technology could be considered as a WTP sludge treatment technique. This literature study aims to determine the sludge characteristics in terms of microplastic and other contaminants, the S/S technology application for sludge treatment, and determine the feasibility of the results for construction materials.
The method used in this study was searching for literature sources related to the study discussion. The sources for this literature study were scientific journals, final assignments, theses, dissertations, and other literature associated with the idea of the study. The required data included WTP sludge content data, sources of pollutants found in WTP sludge, previous research regarding sludge treatment using the S/S method, quality test results on S/S products, as well as quality standard of construction materials. Those data were analyzed to determine the feasibility of PDAM sludge S/S application to be used as materials construction that met the required quality standard.
The S/S technique could bind the contaminants in the WTP sludge, and the products from this technique could be used as material constructions. The sludge characteristics could influence S/S materials composition. For brick, the S/S technique was carried out without a combustion process with the composition of 33,33% WTP sludge cake, 33,33% of cement, and 33,33% of sand (1:1:1). The product had a compressive strength value of 7 MPa, which could be used as a wall construction material. On the other hand, the paving block uses the composition of 25% cement, 22,5% of sludge, and 52.5% of sand. However, this composition could also be applied if Al < 20% total composition and microplastic < 0,42% total composition. The TCLP test result of a mixture of all hazardous materials was < 0,03 mg/L, which means it still under the quality standard. The resulting product has a compressive strength value of 12,4 MPa. It met the minimum quality standard of class C and could be used for construction materials for pedestrian-only roads.
