3. The probability of the Kijing sea terminal
development project in Mempawah, West
Kalimantan being completed on time with a
duration of 595 days based on the project contract
is 55%, or the project has a 45% chance of being
late. Based on the results of the Monte Carlo
method, the Kijing sea terminal development
project in Mempawah, West Kalimantan can be
completed on time with a duration of 606 days.
4. The optimum duration and costs on the critical
path are obtained by adding 1 hour of overtime.
The total duration of the project which was
originally 595 days to 513 days with a difference
of 82 days, with a minimum total cost of
Rp2,740,269,901,670 to Rp 2,740,775,765,420
with a difference of Rp505,863,750 and also The
smallest cost slope of the other overtime hours
scheme is IDR 6,169,070 per day.
