Abstract

Proses stabilisasi/solidifikasi (S/S) menggunakan semen portland banyak digunakan untuk pengolahan limbah B3 yang mengandung logam berat. Penggunaan fly ash dapat mengurangi kebutuhan akan semen, sehingga dapat menurunkan biaya pengolahan. Zat organik berupa hidrokarbon yang seringkali terdapat dalam limbah B-3 dapat mengganggu proses S/S. Penelitian ini bertujuan untuk: (1) menentukan komposisi optimum campuran semen dan fly ash dalam proses S/S limbah B3 sintetik yang mengandung Cu, Cr(VI), dan Pb, (2) menganalisis pengaruh hidrokarbon terhadap mutu produk S/S. Bahan baku S/S dicetak dalam cetakan berbentuk kubus berukuran 5 cm x 5 cm x 5 cm. Variasi komposisi semen dan fly ash yang digunakan adalah 100:0, 90:10, 80:20, 70:30, dan 60:40. Parafin sebagai unsur hidrokarbon ditambahkan pada komposisi campuran semen dan fly ash optimum dengan variasi kadar 2,5%, 5%, 7,5%, dan 10%. Mutu produk S/S diuji dengan uji kuat tekan, Toxicity Characteristic Leaching Procedure (TCLP), dan paint filter test. Hasil penelitian menunjukkan komposisi optimum campuran semen : fly ash adalah 90:10. Komposisi tersebut memiliki nilai kuat tekan 3300 ton/m2, hasil uji TCLP Cu = 0,018 mg/L, Cr(VI) = 0,442 mg/L, dan Pb= 0,033 mg/L. Hasil paint filter test menunjukkan tidak ada cairan bebas yang keluar. Hasil uji TCLP tersebut telah memenuhi baku mutu. Penambahan parafin menunjukkan tidak ada pengaruh signifikan terhadap nilai kuat tekan, namun berpengaruh signifikan terhadap hasil uji TCLP. ==================================================================================================== The stabilization/solidification (S/S) process using portland cement is widely known for treating hazardous waste containing heavy metals. Fly ash addition can reduce the need of cement in order to lower the processing costs. The S/S process can be disturbed by organic compounds which exist in the waste. This research aims to: (1) determine the optimum composition of cement and fly ash in the solidification of simulated wastewater containing copper, chromium (VI), and lead, (2) analyze the effect of paraffin as representative of organic matter on the S/S product quality. Raw materials were molded in cubes of 5 cm x 5 cm x 5 cm size. Composition of type I portland cement and fly ash was varied to 100:0, 90:10, 80:20, 70:30, and 60:4 ratios. Paraffin was added to the optimum composition of cement and fly ash in varied proportions of 2.5%, 5%, 7.5%, and 10%. The S/S product quality was measured using compressive strength, Toxicity Characteristic Leaching Procedure (TCLP), and paint filter tests. Results of this research showed that the optimum composition of cement and fly ash was 90:10. The product had a compressive strength value of 3300 tons/m2, TCLP test results for copper, chromium (VI) and lead of 0.018, 0.442, and 0.033 mg/L respectively. The paint filter test resulted in no free liquid seeped out. All TCLP test results met the quality standards. Paraffin addition gave no significant effect on the compressive strength values, but affected the TCLP test results significantly.
