| Summary: | About 3.54 million km2 area of Indonesia is covered by water with valued
about 82 million USD. Based on data in 2010, Indonesia’s maritime resource was
only utilized about 2.8 million USD. The increase of fuel price has become one of
the main reasons for uncompetitivess fishing vessel in Indonesia, because fuel
costs about 70% of the operational cost.
The purpose of this final project is analyzing feasibility for applied
absorption refrigeration system in commonly fishing vessel for squid with 30
Gross Tonnage capacities in Indonesia. Absorption refrigeration system is
refrigeration system which utilized the heat from flue gas resulted by engine. The
design of an absorption refrigeration system focuses only in generator of
absorption refrigeration system and freezing rooms. Design of freezing rooms
include dimensions, placement, type of insulation, freezing methods, and
operating condition. In addition, this project also is aiming to obtain thermal
properties of squid, appropriate freezing method, and operating condition.
Data and information about fishing vessel was collected by interviewing
several fishermen in Muara Angke, Jakarta. The product are preserved based on
regulation from Food and Drug Administration United States of America (U.S.
FDA) and Food and Agriculture Organization of The United Nation (FAO).
Prediction of thermal properties squid must be done to calculate the freezing load.
Designing the generator, dephlegmator, and freezing room could only be done if
freezing load equals to or more than the recoverable heat from the flue gas.
In this final project, diesel engine with capacity of 235 kW was used in the
30 GT fishing vessel. Fishing vessel is able to sail for 2 months with 5-8 Ton/trip
of captured squid. The engine produces 65.683 kW of energy from the flue gas
and refrigerates 1127.67 kg of squid each day with temperatur about -40oC. The
freezing load consists of 59.025 kW of product load, 0.76 kW of air infiltration
load, 1.928 kW of internal load, and 3.97 kW of transmision load. According to
this analysis, the generator consists of dephlegmator are 110 pipes with 2 meter
long and 0.025 meter outer diameter each. The dephlegmator itself has 0.8 meter
long and 0.0375 meter outer diameter pipe. The freezing process must meet the
criterion of rapid freezing. |
