Abstract
Pabrik gula (PG) Gempolkrep adalah salah satu pabrik
penghasil gula yang terletak di daerah Mojokerto. Jalur sistem
perpipaan dari boiler menuju turbin uap di Pabrik Gula ini
teridentifikasi mengalami pressure drop dan heat loss yang
cukup tinggi, sehingga tekanan dan suhu masuk turbin menjadi
menurun. Pressure drop dan heat loss tersebut akan dijadikan
bahan permasalahan yang akan diteliti pada penulisan skripsi ini.
Sistem perpipaan akan didesain ulang dengan memperpendek
jalur pipa pada sistem distribusi untuk mengurangi pressure
drop dan mengganti bahan isolasi yang digunakan untuk
mengurangi heat loss yang terjadi. Jalur sistem perpipaan
selanjutnya akan dianalisa terkait nilai pressure drop dan heat
loss yang terjadi sebelum proses redesain maupun setelah proses
redesain. Pressure drop pada jalur redesain menurun 1.53
kg/cm2 dibanding jalur existing. Nilai tersebut membuat tekanan
masuk menuju turbin mengalami peningkatan sebesar 8.8%.
Suhu uap rata-rata masuk turbin pada jalur redesain naik 22.935
°C dibanding jalur existing, dengan prosentase kenaikan 7.05%.
Nilai tersebut membuktikaan bahwa proses redesain pada jalur
sistem perpipaan di PG Gempolkrep Mojokerto lebih efektif
dibandingkan dengan jalur existing.

Gempolkrep is one of the factories producing sugar which
is located in Mojokerto. Boiler’s strip piping system to the steam
turbine at this Sugar Factory is identified to have quite high
pressure drop and heat loss so that the pressure and turbine inlet
temperature is lowered. Pressure drop and heat loss reduction
will be used as the issues to be studied in the thesis. The piping
system will be redesigned by shortening the pipeline distribution
system to reduce pressure drop. Replacing the insulation
materials will be used to reduce heat loss that occurs. Trails
piping systems will be analyzed related to the value of pressure
drop and heat loss that occurs before or after redesign process.
Pressure drop on the redesign decreased 1.53 kg/cm2 compared
to the existing line. These conditions make the inlet pressure to
the turbine increased by 8.8%. The temperature average of the
inlet steam turbine on redesign rise 22.935 °C than the existing
line or had 7.05% percentage of increase. This value proved that
redesigning the piping system pathways in PG Gempolkrep
Mojokerto makes the process more effective than the existing
