Abstract—Research on ozone application to extend the shelf life of fresh fish in the refrigerator has been done. Refrigerators where fresh fish deposits are ozone fed through piping systems. Ozone is produced by using Dielectric Barrier Discharge Plasma (DBDP) reactor. The refrigerator has 3 compartments and 1 freezer that has a total volume of 400 L. Ozone loading was done 2 times a day. Ozone can be evenly distributed at 6 mg/L at each compartemnts and freezer. Ozone will last for 60 minutes in the refrigerator. A refrigerator of the same type (but not ozonezed) is provided to place the fish as a control. The fish used in both refrigerators was mackerel fish. The quality of fish were controled by Total Volatile Base Nitrogen (TVBN) and Trimethyl Amin nitrogen (TMA-N) using INS 2354.8: 2009 standard. The freshness of fish was determined through organaleptic number by using INS 01-2729.12006 standard. The results of this study reported that the ozonized refrigerator can maintain the quality of fish in a longer timeframe. The results showed that the value of the fish in the refrigerator TVBN powered ozone standards are still maintained in the range of fresh fish in accordance with INS, which is below the value of 30. While the value TVBN in fish stored in a refrigerator is not energized ozone tends to be higher than those fed ozone, TVBN value in fish stored in the refrigerator without ozone was perishable on the 12th day of each compartment, reaching 30, except in the freezer compartment. On the 16th day, through comparasion of fish freshness (TVBN value), refrigerator not powered by ozone can only be represented by fish stored in the freezer at temperature of -9.28 0C. On the 16th day, energy consumed by refrigerator not powered by ozonewas 34.26 kWh (or 2.66 US $) compared to 9.23 kWh (or 0.72 US $) for refrigerator powered by ozone. These results indicate a huge energy savings by utilizing ozone in the refrigerator. The savings was up to 73%.
