Arahan Pengelolaan Lahan Pada Pit D0-1 Berdasarkan Penilaian Keberhasilan
Reklamasi PT Mahakam Sumber Jaya, Kalimantan Timur

INTISARI
Kegiatan penambangan yang dilakukan dengan sistem penambangan terbuka
akan menyebabkan terjadinya kerusakan terhadap lingkungan. Upaya dalam
memperbaiki dan memulihkan kembali lingkungan bekas tambang yaitu dengan
melakukan kegiatan reklamasi. Dalam kegiatan reklamasi penting dilakukannya
evaluasi keberhasilan reklamasi yang sesuai dengan Peraturan Menteri Kehutanan
Republik Indonesia No. P.60/Menhut-II/2009 Lampiran I agar mengetahui persentase
dari keberhasilan reklamasi, sehingga dapat memberikan rekomendasi arahan
pengelolaan pada lahan reklamasi Pit D0-1 PT Mahakam Sumber Jaya, Kalimantan
Timur.
Metode penelitian menggunakan metode kualitatif dan kuantitatif,
dilakukannya observasi langsung ke lapangan dengan survei dan pemetaan pada lahan
reklamasi kemudian data yang didapatkan akan dianalisis secara matematis dan
dievaluasi. Untuk mengetahui keberhasilan reklamasi dilakukan pengamatan dan
penilaian dari tiga parameter, yaitu pentaan lahan, pengendalian erosi dan sedimentasi,
dan revegetasi. Teknik pengambilan data di lapangan dilakukan dengan Purposive
Sampling. Dalam pengamatannya yaitu dilakukan dengan membuat petak ukuran yang
memiliki ukuran 40 m x 25 m. Setelah melakukan pengumpulan data di lapangan
selanjutnya data akan diolah dan dianalisis dengan analisis matematis dan deskriptif.
Hasil yang telah dihitung akan dilakukan pembobotan nilai berdasarkan pada
Peraturan Menteri Kehutanan Republik Indonesia No. P.60/Menhut-II/2009 Lampiran
I, agar mendapatkan hasil persentase keberhasilan reklamasi yang nantinya akan
digunakan sebagai dasar penentuan rekomendasi arahan pengelolaan.
Penilaian keberhasilan kegiatan reklamasi pada Pit D0-1 PT Mahakam Sumber
Jaya memiliki nilai sebesar 94%. Rekomendasi arahan pengelolaan yang dapat
dilakukan yaitu dengan pendekatan teknis dengan membuat teras guludan.
Penanganan erosi dan sedimentasinya dengan membuat rekayasa pengendali erosi
berupa dam penahan dari kayu dan dam struktur dari ban, dan pemilihan jenis tanaman
penutup tanah. Dengan adanya rekomendasi arahan pengelolaan tersebut dapat
meningkatkan nilai keberhasilan reklamasi menjadi 98%.

Land Management for Pit D0-1 Based on Assessment of Reclamation Success of
PT Mahakam Sumber Jaya, East Kalimantan

ABSTRACT
Mining activities carried out with an open pit mining system will cause damage
to the environment. Efforts to repair and restore the former mining environment are by
carrying out reclamation activities. In reclamation activities, it is important to evaluate
the success of reclamation in accordance with the Regulation of the Minister of
Forestry of the Republic of Indonesia No. P.60/Menhut-II/2009 Appendix I in order to
find out the percentage of success of reclamation, so that it can provide management
recommendations for the reclamation land of Pit D0-1 PT Mahakam Sumber Jaya,
East Kalimantan.
The research method uses qualitative and quantitative methods, direct field
observations are carried out with surveys and mapping on reclamation land then the
data obtained will be analyzed mathematically and evaluated. To determine the success
of reclamation, three parameters were observed and assessed, namely land planning,
erosion and sedimentation control, and revegetation. Data collection techniques in the
field were carried out by purposive sampling. In his observations, it was done by
making a size plot that had a size of 40 m x 25 m. After collecting data in the field, the
data will then be processed and analyzed with mathematical and descriptive analysis.
The results that have been calculated will be weighted according to the Regulation of
the Minister of Forestry of the Republic of Indonesia No. P.60/Menhut-II/2009
Appendix I, in order to obtain the results of the percentage of successful reclamation
which will later be used as a basis for determining recommendations for management
directions.
The assessment of the success of reclamation activities at PT Mahakam
Sumber Jaya Pit D0-1 has a value of 94%. Recommendations for management
directions that can be carried out are with a technical approach by making mound
terraces. Erosion and sedimentation can be handled by constructing erosion control
engineering in the form of wooden retaining dams and tire structural dams and
selecting the types of ground cover plants. With the recommendations for management
directives, the success rate of reclamation can increase to 98%.
