Abstract
ABSTRACT
Mining activities have an impact on environmental damage, so that is very
required reclamation activities. Therefore, it is always followed by mining
reclamation activities. This research was done in PT Kaltim Prima Coal’s
reclamation land areas aged 0 month, 3 months, 6 months, and 12 months. PT
Kaltim Prima Coal is one of many companies engaged in coal mining in Sangatta.
One of the criteria for reclamation success rate can be seen from the level of erosion
that occurred in the reclamation land. This study has the objective to know the rate
of infiltration and erosion that occurred in PT Kaltim Prima Coal’s reclamation land
with age difference.
The methods used in this research are survey method, laboratory analytical
method, and mathematical analysis method. Laboratory analysis method is useful to
determine the weight of the volume of soil, which will be used in a mathematical
method for determining the rate of erosion. The rate of infiltration and erosion
measurements was done directly in the field used double ring infiltrometer and
erosion sticks method.
Based on this research, it is known that reclamation’s age affects the rate of
infiltration and erosion. If reclamation’s age is older, then the rate of infiltration will
be higher. As for the rate of erosion, if reclamation’s age is older, then the rate of
erosion will be lower.
Keywords: mining, reclamation, infiltration, erosion.
INTISARI
Kegiatan penambangan berdampak pada kerusakan lingkungan, sehingga
kegiatan reklamasi pun sangat diwajibkan oleh karena itu kegiatan penambangan
selalu diikuti oleh kegiatan reklamasi. Penelitian dilakukan di lahan reklamasi PT
Kaltim Prima Coal yang berumur 0 bulan, 3 bulan, 6 bulan, dan 12 bulan. PT Kaltim
Prima Coal merupakan salah satu perusahaan yang bergerak dalam bidang
pertambangan batubara di Sangatta. Salah satu kriteria tingkat keberhasilan
reklamasi dapat dilihat dari tingkat erosi yang terjadi di lahan reklamasi tersebut.
Penelitian ini bertujuan untuk mengetahui laju infiltrasi dan erosi yang terjadi di
lahan reklamasi PT Kaltim Prima Coal dengan perbedaan umur.
Metode yang digunakan dalam penelitian adalah metode survei, metode
analisis laboratorium, dan metode analisis matematis. Metode analisis laboratorium
dilakukan untuk menentukan berat volume tanah, yang nantinya akan digunakan
dalam metode matematis untuk menentukan laju erosi yang terjadi. Pengukuran laju
infiltrasi dan erosi dilakukan langsung di lapangan dengan menggunakan double ring
infiltrometer untuk pengukuran infiltrasi dan metode tongkat erosi untuk pengukuran
erosi.
Berdasarkan hasil penelitian, maka dapat diketahui bahwa umur reklamasi
mempengaruhi laju infiltrasi dan erosi. Semakin tua umur reklamasi maka laju
infiltrasi akan semakin tinggi. Sedangkan untuk laju erosi, semakin tua umur
reklamasi maka laju erosi akan semakin rendah.
Kata Kunci: penambangan, umur reklamasi, infiltrasi, erosi.
