Abstract
Air asam tambang (AAT) merupakan hasil reaksi oksidasi pyrite
dengan air dan oksigen yang menghasilkan asam. Kandungan
utama dalam AAT adalah logam Fe yang didominasi oleh
senyawa FeSO4 dan Fe2(SO4)3, senyawa tersebut merupakan
koagulan yang biasa digunakan dalam pengolahan air. Dalam
penelitian ini digunakan AAT sebagai koagulan untuk pengolahan
air run off pertambangan batu bara dengan koagulasi dua tahap
satu jenis koagulan (AAT-AAT) dan dua jenis koagulan (AAT-
clarifix dan AAT-PAC). Tujuan dari penelitian ini adalah
menentukan dosis dan perbandingan optimum untuk masing-
masing koagulan serta pengaruh jenis AAT, perbandingan dosis
AAT, dan dosis koagulan kedua terhadap efisiensi pengolahan.
Pada penelitian ini dilakukan variasi terhadap perbandingan dosis,
dosis koagulan kedua, dan pH awal sampel. Analisis laboratorium
untuk parameter pH, TSS, kekeruhan, Fe dan Mn. Penentuan
pengaruh tiap variasi menggunakan perhitungan statistik dengan
metode Anova dan Manova.
Koagulasi dua tahap (AAT-AAT) penelitian A menghasilkan
efisiensi tertinggi pada perbandingan 75:25, yaitu menyisihkan
99,4% TSS dan 99,6% kekeruhan pada pH optimum 7,86. Pada
koagulasi 75% AAT-0,04 mL/L clarifix dapat menyisihkan 99,7%
TSS dan 96,3% kekeruhan. pH optimum proses koagulasi AAT-
clarifix adalah 6,5-7,5. Sedangkan koagulasi 75% AAT-20 mg/L
PAC menyisihkan 100% TSS dan 99,8% kekeruhan. pH optimum
koagulasi AAT-PAC adalah 6-7,5. Berdasarkan analisis statistik,
jenis AAT mempunyai pengaruh signifikan pada koagulasi AAT-
AAT. Perbandingan dosis AAT berpengaruh pada koagulasi AAT-
clarifix. Sedangkan pada AAT-PAC, dosis PAC memberikan
pengaruh lebih signifikan dibandingkan perbandingan AAT.

Acid mine drainage (AMD) is the result of pyrite oxidation
reaction with water and oxygen that produces acid. The main
content of the AMD is Fe, which is dominated by FeSO4 and
Fe2(SO4)3, these compound are commonly used as a coagulant in
water treatment. In this study AMD was used as a coagulant in
water treatment of coal mining run off with two-stage coagulation
which use one type coagulant (AMD-AMD) and two types
coagulants (AMD-clarifix and AMD-PAC). The purpose of this
study is to determine the optimum dose and ratio for each
coagulant dose and also the effect of different type of AMD, AMD
dose ratio, and dose of second coagulant on treatment efficiency.
Variation in this research were dose ratio, second dose of
coagulant, and the initial pH of the sample. Laboratory analysis
for pH, TSS, turbidity, Fe and Mn parameter. Determination of
the effect of each variation using statistical calculations with
Anova and Manova methods.
Two stages coagulation (AMD-AMD) in experiment A, produced
the highest efficiency at ratio 75:25, which had efficiency removal
for TSS and turbidity were 99,4% 99,6% respectively at optimum
pH 7,86. Coagulation of 75% AMD-0,04 mL/L clarifix had removal
efficiency of TSS and turbidity were 99,7% and 96,3%. The
optimum pH of AMD-clarifix coagulation was range at 6,5-7,5.
While coagulation of 75% AMD-20 mg/L PAC had removal
efficiency of TSS and turbidity were 100% and 99,8%
respectively. The optimum pH of AMD-PAC coagulation was 6 to
7,5. Based on statistical analysis, the type of AMD had a
significant effect on AMD-AMD coagulation. Dose ratio had
siginificant effect on AMD-clarifix coagulation. While on AMD-PAC
coagulation, variation dosage of PAC had more significant effect
than the dose ratio of AMD.
