Abstract
Sebagai sarana transportasi yang memuat makhluk hidup berupa
hewan ternak, kapal pengangkut ternak membutuhkan desain
sistem ventilasi khusus pada ruang muat guna menjaga agar
hewan ternak terhindar dari heat stress akibat temperatur dan
rasio kelembaban yang tinggi. Salah satu upaya untuk
menghindari rasio kelembaban yang tinggi adalah memberikan
suplai udara kering dengan menggunakan desiccant. Tujuan
skripsi ini adalah merencanakan sistem ventilasi dengan twowheel
desiccant melalui analisa perhitungan terhadap penurunan
rasio kelembaban udara setelah melewati dua rotor desiccant serta
pemenuhan kebutuhan alat pemanas dan sistem pendinginnya
menggunakan panas gas buang dan air kondensat mesin AC. Dari
hasil analisa didapatkan hasil bahwa untuk memberikan suplai
udara pada ruang muat sebesar 41221 m3/h, diperoleh spesifikasi
dua rotor desiccant yang memiliki diameter 2190 mm dengan
ketebalan 200 mm untuk menurunkan rasio kelembaban udara
luar sebesar 26.1 gw/kgda menjadi 14.70 gw/kgda. Temperatur udara
hasil dehumidifikasi sebesar 72.8oC akan diturunkan menjadi
26oC dengan menggunakan koil pendingin dan media pendingin
lain berupa air kondensat. Penggunaan air kondensat sebagai
media pendingin mampu mengurangi beban pendinginan sebesar
18.41 kW dari total kebutuhan pendinginan sebesar 490.63 kW,
sedangkan untuk kebutuhan pemanas udara reaktivasi sebesar
412.57 kW akan dipenuhi dengan memanfaatkan daya dari panas
gas buang sebesar 440.99 kW.

Livestock carrier was a special ship carried in the form of
livestock that needed special air ventilation system on the cargo
hold for preventing them from heat stress due to high temperature
and high humidity ratio. One of the ways used to decrease
excessive air humidity ratio was to provide dry air by using
desiccant dehumidifier. The purposes of this thesis were to design
an alternative air ventilation system by using two-wheel desiccant
through calculation analysis of humidity ratio reduction after the
air passed through two desiccant wheels, and also it needs of
heater and cooling system by using heat capacity of exhaust gas
and condensate water from Air Conditioning (AC) machine. The
result of the analysis shown that 41221 m3/h of cargo hold air
capacity requirements was able to be supplied by two desiccant
wheels which has 2190 mm of diameter, and 200 mm wheel depth.
The humidity ratio of outside air was about 26.1 gw/kgda would be
reduced into 14.70 gw/kgda through dehumidification process. The
air temperature after dehumidification process increased up to
72.8oC and would be cooled into 26oC by configuring a cooling
coil and also used condensate water as a cooling medium. The
used of condensate water as a cooling medium was able to reduce
18.41 kW of total cooling load requirements of 490.63 kW, then
for 412.57 kW heat capacity requirements for reactivation air
heater would be supplied by using heat capacity of exhaust gas as
440.99 kW.
