UPAYA STABILISASI KADAR pH DAN TOTAL SUSPENDED SOLID (TSS)
AIR LIMBAH TAMBANG BATUBARA DI AREA SETTLING POND 8 PT
MADHANI TALATAH NUSANTARA WEST PIT PROJECT

INTISARI
Permasalahan yang masih terjadi di area settling pond 8 PT Madhani Talatah
Nusantara West Pit Project yaitu belum stabilnya parameter Total Suspended Solid
(TSS) yang akan berdampak pada penurunan kadar oksigen terlarut dan indeks
keanekaragaman hayati. Hal tersebut diindikasikan dengan keruhnya air pada settling
pond 8 saat dilakukan pengamatan dan pengecekan langsung di lapangan. Pada
pengelolaan kadar TSS menggunakan tawas juga perlu memperhatikan kadar pH pada
kolam pengendapan. Oleh karena itu, tujuan dari penelitian ini untuk mengetahui
karakteristik air limbah tambang batubara, menganalisis efektivitas pengelolaan kadar
pH dan TSS, mengetahui dosis optimum penggunaan tawas dan kapur, serta
memberikan rekomendasi arahan pengelolaan untuk mengoptimalisasi pengelolaan air
limbah tambang batubara terhadap parameter pH dan TSS.
Metode pengumpulan data dilakukan dengan survei dan pemetaan terhadap
rona lingkungan, pengambilan sampel dengan teknik purposive sampling. Uji
laboratorium dilakukan pengujian kadar pH dengan pH meter sesuai dengan SNI 06-
6989 11-2004 serta pengujian TSS menggunakan metode gravimetri sesuai SNI 06-
69893-2004. Penelitian ini juga menggunakan metode jar test untuk mengetahui dosis
optimum yang mengacu pada SNI 19 6449 2000. Metode analisis deskriptif digunakan
untuk mengetahui kualitas air limbah tambang batubara sesuai Pergub Kalimantan
Selatan Nomor 36 Tahun 2008. Analisis kuantitatif dan korelasi pearson dilakukan
untuk mengetahui kuantitas serta hubungan antara debit aliran dengan kadar pH dan
TSS.
Hasil penelitian menunjukkan kadar TSS area inlet, segmen 1, dan segmen 2
belum memenuhi baku mutu, sedangkan kadar TSS area segmen 3, 4 dan outlet sudah
memenuhi baku mutu. Kadar pH yang telah diukur pada keseluruhan titik sampling
diketahui sudah memenuhi baku mutu. Efektivitas kenaikan kadar pH dan penurunan
kadar TSS masing – masing sebesar 4,83% dan 69,91%. Dosis optimum tawas dan
kapur masing – masing didapatkan 250 mg/l serta waktu pengendapan optimal selama
180 menit. Arahan pengelolaan yang direncakan berupa perhitungan kebutuhan tawas
dan kapur, penambahan perencanaan bangunan injeksi bahan kimia, penambahan
tanggul di antara kolam pengendapan dan lereng untuk mengantisipasi peningkatan
kadar TSS akibat debit limpasan akibat peristiwa erosi.

EFFORTS TO STABILIZE PH LEVELS AND TOTAL SUSPENDED SOLID
(TSS) COAL MINING WASTEWATER IN THE SETTLING POND 8 AREA

ABSTRACT
Problem that still occurs in the settling pond 8 area of PT Madhani Talatah
Nusantara West Pit Project is the unstable Total Suspended Solid (TSS) parameter
which will have an impact on reducing dissolved oxygen levels and biodiversity
indices. This is indicated by the murky water in settling pond 8 during direct
observation and checking in the field. In managing TSS levels using alum, it is also
necessary to pay attention to the pH level in the settling pond. Therefore, the purpose
of this study is to determine the characteristics of coal mine wastewater, analyze the
effectiveness of managing pH and TSS levels, determine the optimum dose of alum
and lime use, and provide recommendations for management directions to optimize
coal mine wastewater management of pH and TSS parameters.
Method of data collection was carried out by surveying and mapping the
environmental baseline, and taking samples using technique purposive sampling.
Laboratory tests were carried out by testing the pH level with a pH meter according to
SNI 06-6989 11-2004 and TSS testing using the gravimetric method according to SNI
06-69893-2004. This study also used the jar test method to find out the optimum dose
referring to SNI 19 6449 2000. The descriptive analysis method was used to determine
the quality of coal mine wastewater according to South Kalimantan Governor
Regulation No. 36 of 2008. Quantitative analysis and pearson correlation were carried
out to determine quantity and relationship between flow rate and pH and TSS levels.
The results of the study showed the level of area TSS inlet, segment 1, and
segment 2 have not met the quality standards, while the TSS content of segments 3, 4,
and outlet already met the quality standard. The pH levels that have been measured at
all sampling points are known to have met the quality standards. The effectiveness of
increasing pH levels and decreasing TSS levels was 4.83% and 69.91%, respectively.
The optimum dose of alum and lime each obtained was 250 mg/l and the optimal
settling time was 180 minutes. The planned management directives are in the form of
calculating the need for alum and lime, adding chemical injection building plans,
adding embankments between settling ponds and slopes to anticipate increasing TSS
levels due to runoff discharge due to erosion events.
