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.
