The ozone technology fish storage system (OTFIS) can be applied in the fishing boat, fish storage in the Fish Auction Market, fish storage in the means transport for fish. In this research, we produced a prototype that was integrated by the fish container and ozone generator. We used Dielectric Barrier Discharge Plasma (DBDP) technology for ozone generator. The characterization of ozone generator has been carried out and showed that ozone generator can produce ozone concentration from 0.5 ppm to 12 ppm. The ozone concentration in the area is very suitable to be used in food technology. The ozone treatment was performed on red tilapia representing the white-fleshed fish with ozone concentrations from 0.5 ppm to 4.5 ppm. The results of this treatment showed that organoleptic and TVBN of fish were still appropriate with Indonesian National Standard (INS). Beside that, TPC testing has been done on the red tilapia showed that the higher the ozone concentration the smaller the remaining of bacteria colonies. Similarly, for a variable of time, the longer the exposure to ozone the less the remaining of colonies. The results of this study have been adapted to realize of OTFIS with a size of 50 cm x 50 cm x 100 cm (250 liters) and can accommodate as much as 100 kg of fish.

INTRODUCTION The Indonesian marine fisheries potential spread in nearly all parts of the existing Indonesian waters as the territorial sea of the archipelago and the waters of Exclusive Economic Zone (EEZ). The Indonesian sea area is estimated at 5.8 million km 2 with the longest coastline in the world at 81.000 km and the cluster of islands as much as 17.508. This geographical situation has the potential of fish estimated as many as 6.26 million tons per year. This amount can be detailed as much as 4.4 million tons can be caught in the waters of Indonesia and 1.86 million tons can be obtained from Indonesian Exclusive Economic Zone (IEEZ) waters. According to the Ministry of Maritime and Fisheries, the Indonesian marine fisheries nominal value of 57.69 trillion IDR, or the equivalent of 6.48 percent of GDP in 2012, while the value of economic activity around 255.3 billion IDR. The potential to grow by 7 percent if compared to the second quarter 2013 to the second quarter of 2012 [1]. In addition to marine fisheries, Indonesia also has great potential for freshwater fisheries. The sector of freshwater fish aquaculture in Indonesia has the potential to be developed through the extension and intensification. The commodities of freshwater fish farming such as catfish, carp, tilapia, and freshwater ornamental fish have a fairly high demand in domestic and export markets. Export markets demand a positive impact on the increase in Indonesia’s foreign exchange. The fishery export is closely related to the quality of fish delivered, while the quality of the fish was associated to fish storage technology from the whole process of traveling fish caught up to the consumer. Currently, there are several methods for preserving fish using methods including drying, curing, salting, fermentation, and the most commonly used is cooling. Most people in ways that can be harmful to health, for example by using formalin for preservation of fish. From the above discussion it can be concluded that, fish storage technology has not been able to keep the quality of the fish. The new technology is needed to resolve the issue. The alternative is ozone technology. The utilization of appropriate ozone technology and ozone dose right is believed to be used for storage technology in the whole his journey process begin caught to the consumer. The ozone technology has been developed for the water sterilization process, vegetable or food, medical equipment, and various other applications. In 1995, ozone was declared safe by Generalize Recognized as Safe (GRAS) or was generally recognized to be safe by the FDA (U.S. Food and Drug Administration) for the treatment of drinking water bottles. These applications are then developed as "GRAS" for food processing by some experts the last few years [2]. Ozone can be produced using two electrodes fed by high voltage with gas fill between the two electrodes in the form of pure oxygen gas or air. Between the two electrodes is covered by a dielectric material in order to avoid the occurrence of arc discharge. The factors that can affect ozone formation in general are voltage, dielectric materials, the pressure, the configuration system of the plasma reactor, and a gas in the plasma reactor [3,4,5]. Ozone formation involves mechanism of ionization and recombination both dissociation and association. The reaction of ozone formation can be occured in a plasma reactor [6]. 2014 International Symposium on Technology Management and Emerging Technologies (ISTMET 2014), May 27 - 29, 2014, Bandung, Indonesia 978-1-4799-3704-2/14/$31.00 ©2014 IEEE 167 brought to you by CORE View metadata, citation and similar papers at core.ac.uk provided by Diponegoro University Institutional Repository
