Abstract :
Asam Nitrat merupakan salah satu produk industri kimia yang digunakan sebagai
bahan baku industri kimia, bahan baku peledak, nitrating agent, oxidizing agent,
pelarut, katalis dan hydrolizing agent. Asam Nitrat dapat di produksi dengan
beberapa proses yaitu 1) Proses Oksidasi Ammonia, 2) Proses Retort, dan 3)
Proses Electrical Arc. Dalam Pra-Rancangan Pabrik Asam Nitrat ini dipilih proses
Electrical Arc yang lebih menguntungkan dari segi ekonomi dan termodinamika
dibandingkan proses lainnya.
Kapasitas produksi pabrik direncanakan 55.000 ton/tahun dengan 330 hari kerja
dalam 1 tahun. Lokasi pabrik direncanakan didirikan di Kawasan Industri Gresik,
Kab. Gresik, Jawa Timur. Tenaga kerja yang dibutuhkan sebanyak 168 orang
dengan bentuk badan usaha Perseroan Terbatas (PT) yang dipimpin oleh seorang
Direktur Utama yang dibantu oleh Direktur Produksi dan Direktur Pemasaran dan
Keuangan dengan struktur organisasi line and staff.
Dari analisis ekonomi diperoleh:
Fixed Capital Investment (FCI) = Rp 442.854.394.558
Working Capital Investment (WCI) = Rp 78.150.775.510
Total Capital Investment (TCI) = Rp 521.005.170.068
Break Even Point (BEP) = 30,51%
Shut Down Point (SDP) = 12,25%
Pay Out Time before taxes (POT)
= 2,19 years
Pay Out Time after taxes (POT)
b
= 2,59 years
Return on Investment before taxes (ROI)
a
= 30,32%
Return on Investment after taxes (ROI)
b
= 24,26%
Discounted cash flow (DCF) = 24,73%
Mempertimbangkan rangkuman di atas, sudah selayaknya pendirian pabrik Asam
a
Nitrat ini dikaji lebih lanjut, karena merupakan pabrik yang menguntungkan dan
mempunyai prospek yang baik.

Nitric Acid is one of the chemical industry products used as raw material for
chemical industry, explosive raw material, nitrating agent, oxidizing agent,
solvent, catalyst and hydrolizing agent. Nitric Acid can be produced with several
processes namely 1) Ammonia Oxidation Process, 2) Retort Process, and 3)
Electrical Arc Process. On the Manufacturing of Nitric Acid was selected
Electrical Arc process that is more profitable in terms of economics and
thermodynamics than other processes.
This Plant is meant to produce 55.000 tons/year with operation time 24 hours/day
and 330 days on a year. This Plant is planned to be built in Gresik, Kab. Gresik,
Jawa Timur. The bussines entity form of this plant is Limited Liability Company
(Ltd) using line and staff organizational structure with 168 labors.
From the economic analysis, it is obtained that :
Fixed Capital Investment (FCI) = Rp 442.854.394.558
Working Capital Investment (WCI) = Rp 78.150.775.510
Total Capital Investment (TCI) = Rp 521.005.170.068
Break Even Point (BEP) = 30,51%
Shut Down Point (SDP) = 12,25%
Pay Out Time before taxes (POT)
b
= 2,19 years
Pay Out Time after taxes (POT)
a
= 2,59 years
Return on Investment before taxes (ROI)
b
= 30,32%
Return on Investment after taxes (ROI)
a
= 24,26%
Interest Rate of Return (IRR) = 24,73%
Consider the summary above, it is proper establishment of Nitric Acid Plant is
studied further, because the plant is profitable and has good prospects.
