Study And Ukl Upl Of Post Mining Activities In Rock Andesit PT Desira Guna Utama Main Site Kp Bolang Argapura Village Office Siwaluh Mountain Districts Cigudeg, District Bogor, West Java Province

Abstract

PT Desira Guna Utama engaged in the mining of andesite to study Environmental
Management Effort (UKL) and Environmental Monitoring Effort (UPL), to identify and plan for
post-mining activities andesite technically, identify environmental impacts that occur on the
activities of the post-mining technically, impact arising either positive impacts and negative
impacts.
Knowing the state of the initial hue and the hue of the final physical state of the
post-mining activities planned andesite PT Guna Utama Desira technically. Identifying the
environmental impacts that occur in post-mining activities includes the reclamation plan, and
prepare for mine closure converting the land into productive land mines after mining is
completed. Planning for environmental management and monitoring are better for the
environment as a result of mining activities in Desira Guna Utama PT Gunung Siwaluh, Site
Kp. Bolang Argapura Village, District Cigudeg, Kab. Bogor.
Mining system andesite related to the disposal of overburden applied by PT Desira
Guna Utama is to dig (cut) and piled back (back filling). Plan for post-mining and reclamation
activities to be undertaken by PT Desira Guna Utama as follows: securing mined lands,
setting landform includes surface water quality control, and revegetation replanting postmining
land.
The environmental impact of mine closure andesite cause environmental damage
to the soil due to a decrease in the elevation of the land demolition. Reclamation activities
carried out to restore the land has been open as a result of mining activities by backfilling
with soil top soil and fertilizer to restore soil nutrients after post-mining activities. Preparation
closure to minimize the damage arising from mining activities by planning land that needs to
be done to achieve the reclamation and revegetation success criteria of mine closure and
reclamation. Experts in land use from pit mining is done to minimize flooding that occurred in
the pits due to the intensity of high rainfall, longso happens on a slope bekaan openings
mine done by making an embankment on the edges of slopes which are useful as drains or
drainage to prevent landslides ,
