4.2.2. DSS Tool Analysis
Until this research conducted, the implementation of government regulation of mine reclamation activity runs in under optimal way. It caused of
inconsistency regulation that issued by the central government and local government, as the amount of reclamation bond is quite less than the environment
cost that should be paid by Mine Company. The case happened in South Kalimantan where the local government regulate that every mining company
should pay Rp. 50.000.000 per 2 ha of opened area or Rp 2.000 ton of coal for reclamation bond. This value is lesser than actual environmental cost impact that
has to be released, which is about two hundred until three hundred million rupiah per hectare.
By constructing this rehabilitation bond DSS Tool, central government especially DEMR try to arise a pilot project model of rehabilitation bond for mine
reclamation activities. It will be socialized to local government to be used in order to give a good implementation of mine government regulation of reclamation

The analysis of this rehabilitation bond system focuses on reclamation bond comparison and analysis between actual direct cost components content of
reclamation cost with the planned one. Beside the mine report submission for reclamation bond planning, this application tries to calculate it with mine
reclamation data report. The tolerance value for the comparison analysis is based on the percentage
of reclamation bond amount that reported mining company close to the reclamation bond calculation using the number of escalation factor, which is
represent using percent default value 10 to 20. The escalation factor is added value, which represent financial fluctuation such annual inflation factor.
The category of comparison consists of ‘Good’ mark represented with green color, ‘Intermediate’ mark represented with yellow color and ‘Bad’ mark
represented with red color. ‘Good’ mark stated that if the amount of actual reclamation bond from mining company is ranging between
±10 of calculated reclamation bond. ‘Intermediate’ mark stated that if the amount of actual
reclamation bond from company is around 10-20 greater or less from calculated reclamation bond, and ‘Bad’ mark stated that if the amount of actual reclamation
from mining company is greater or less than 20 from calculated reclamation bond.
Based on data from PT.NNT’s reclamation activities period year 2001 to 2005 data, current actual reclamation bond from year 2001 to 2005 is about +
30,693,782.00 compared to calculated reclamation bond of the application is about 35,776,292.60 with variance around 5,082,510.6. According to the bond
category constrain, this value is categorized as ‘Intermediate’. This indicate that the amount of total reclamation bond for 5 years period 2001 to 2005 still need to
be corrected by the company throughout presentation or inviting them to give details explanation of the way they achieved that value.

Figure 4.18. Equipment and Labour Cost form
The government will store mining company reclamation bond and the stored bond included its annual bank interest will be accumulated into reclamation
bond. If the company is default or not performing land reclamation as ruled by the government and company annual reclamation, the government will offer the
reclamation work to third party through work tender. The tolerance in awarding company into ‘Good’, ‘Intermediate’ or ‘Bad’ is based on valid bank interest
about 10. If the award is ‘Good’ then the company does not need to add their money, as the bank interests of reclamation bond will cover it. If the award is
Intermediate, then mining company will add the remnant of that 10 and if the award is bad then the reclamation bond will be offered to third party.
The variance value that shown on Figure 4.18 can be clearly explained if
the reclamation bond separated into components of direct cost and indirect cost.
Here with following the breakdown of PT.NNT’s reclamation bonds Table 4.4 and calculated reclamation bond Table 4.5 shows that the amount direct cost
and indirect cost with the percentage in period 2001 to 2005.

The comparison of the amount of reclamation bond conducted annually. Constant value of reclamation bond is straight form year 2002 to 2005 with small
variance not more than one million dollar. High variance of annual reclamation cost in year 2001 shows that calculated reclamation cost is higher around 2.5
million dollar than PT.NNT report. The reason of mine facility mobilization and demobilization activity is usually happen in the beginning of exploitation phase
and sometime need sub-contractors as partner to finish this activity. The report of technical mine activity in 2001 was submitted by PT.NNT in the beginning year
2001 has include reclamation activity and cost expenditure, exclude mine facilities removal caused of their activities started in year 1996 and mining lifetime around
40 years. Therefore mine facilities removal will plan closed to the end of mine
56
closure. This variance also implicates the value of indirect cost especially for equipment administration cost.
The amount of indirect cost was based on total amount of direct cost. The percentage of indirect cost determined as normally rules that fixed in particular
range by DEMR. For instance, the percentage of mobilization and demobilization of heavy equipment cost around 2.5 to 10 from total direct cost. Reclamation
planning cost was determined around 2 to10 . Administration and contractor’s profit cost was determined around 3 to 14 and management fee
was determined around 2 to 7 . This fixed range of indirect cost percentages used to determine the amount
of indirect cost in Reclamation Bond Application. Comparing with PT.NNT’s reclamation report activities, the percentage of equipment mobilization placed in
small value and closed to average about 0.53 per year, later the percentage of contractor’s profit exceeds from government regulation with highest value around
20.95 in year 2001.Therefore the possibility reason of these phenomena that happen in year 2001 caused of outsourcing supporting project of reclamation
activity where implicate to the lower percentage of equipment mobilization and highest percentage of contractor’s profit. The evidence also can be looked up with
the highest percentage of reclamation planning cost about 9.43 and supervision cost about 7.33 in year 2001.
Meanwhile, the comparison in year 2002 later illustrates indifference calculation of reclamation bond. It was figured by the rate of total reclamation per
year starting from 2002 up to 2005 with variance value not more than one million dollar such as 513,106 in year 2002, 53,497 in year 2003, 425,500 in year
2004 and 796,024 in year 2005. The highest value of previous variance placed in year 2005 with caused of the high difference in mobilization equipment rate
and reclamation plan rate.
