ABSTRACT
Urea is a strategic nitrogen-based petrochemical product used in both the agricultural and
industrial sectors as a raw material for resins, adhesives, and plastics. In addition, in the
automotive sector, urea is utilized in Selective Catalytic Reduction (SCR) technology to reduce
nitrogen oxide (NOx) emissions. Global urea demand is projected to continue increasing with a
Compound Annual Growth Rate (CAGR) of 1.5% during the 2025–2033 period. Domestic
demand reached 6.2 million tons in 2023 and is expected to keep growing in line with increasing
food needs, presenting a significant opportunity for Indonesia to expand its production capacity
and become a major urea producer. A urea plant using the Stamicarbon process is planned to
be established in Bontang City, East Kalimantan Province, in 2029, with a production capacity
of 350,000 tons per year.
The stamicarbon process consists of two main reactions: the formation of ammonium
carbamate and the dehydration reaction to form urea. The raw materials used in urea production
are ammonia and CO₂, supplied by PT Kaltim Parna Industri and PT Samator Indo Gas Tbk,
both located in Bontang City, East Kalimantan. The electricity demand of the plant is supplied
by PLTU KALTIM 2 × 100 MegaWatt Teluk Kadere Bontang Lestari and generator sets, with
a total electricity requirement of 1,811.590 kW. The water source for the urea plant is seawater
from the Makassar Strait, with a total water requirement of 113,089.049 kg/hour. The gaseous
waste generated consists of residual gases, inert gases, and water vapor. Meanwhile, liquid and
solid waste originates from laboratory and domestic activities, with a total waste flow rate of
5,064.583 kg/hour. Process control in the urea plant is managed using instrumentation such as
sensors, indicators, controllers, recorders, and safety devices like alarms.
Profitability analysis showed that the urea plant with a capacity of 350,000 tons per year
was economically feasible to be established. The project resulted in a Payback Period of 3 years
and 22 days, an Internal Rate of Return (IRR) of 25.27%, a Break-Even Point (BEP) of 55.60%,
a Net Present Value (NPV) of Rp 6,381,651,250,583, and a Return on Investment (ROI) of
23.95%. These results met the feasibility criteria (IRR > 8% and ROI > 20%) with a medium
risk level. Therefore, the development of a urea plant with a production capacity of 350,000 tons
per year was considered prospective and expected to meet domestic and global demand.
