Abstract
Dalam operasionalnya, PLTU Unit IV sering terjadi
kebocoran pada tube kondensor yg digunakan untuk menyalurkan
air pendingin. Hal ini berdampak pada ketidakstabilan performa
kondensor secara keseluruhan. Salah satu upaya untuk
meningkatkan performa kondensor yakni dengan menggunakan
material yang tahan korosi dan mempunyai laju perpindahan
panas yang tinggi. Oleh karena hal tersebut, maka akan diadakan
penelitian yang membandingkan performa kondensor
menggunakan material tube aluminium brass dengan titanium.
Titanium dipilih karena memiliki sifat tahan korosi tinggi dan
mempunyai konduktivitas termal yang baik
Proses perhitungan laju perpinndahan panas dilakukan
dengan metode Log Mean Temperature Different (LMTD).
Sedangkan untuk perhitungan Effectiveness digunakan metode
Number of Transfer Unit (NTU). Perhitungan dilakukan dengan
data kevakuman dan temperatur yang sama agar hasilnya dapat
terfokus pada perbedaan material tube.
Setelah dilakukan perhitungan, nilai laju perpindahan
panas total dari material aluminium brass 29,449280 MW dan
pada material titanium sebesar 28,530623 MW. Sedangkan untuk
nilai resistansi korosinya, material titanium lebih tahan terhadap
air laut daripada material aluminium brass

Power Plant Unit IV frequent leaks in condenser tube
which is used to supply cooling water . This has an impact on the
overall instability of the performance of the condenser . One
effort to improve the performance of the condenser using a
corrosion-resistant material and has a high rate of heat transfer.
In this case the authors are interested in comparing the
performance of the condenser which uses aluminum brass tube
with titanium material . Selection of titanium because of its high
corrosion resistance and good thermal conductivity
The method used in this calculation of the heat
transfer-rate and effectiveness is Log Mean Temperature
Difference (LMTD) and Number of Transfer Unit (NTU) Method
to calculate the effectiveness. This method of data calculated by
same vacuum pressure and temperature, so that the results are
focused on material differences tube
The results obtained by value of the rate of heat
transfer which is aluminium brass is 29,449280 MW, and
titanium is 28,530623 MW. While for the value of the corrosion
resistance , titanium material more resistant to sea water than
aluminum material brass
