Abstract

ABSTRACT

 Until now there is no standard destruction protocol for the traffic of imported fish products and/or frozen fish contaminated with HPIK. The technique of destroying frozen catfish (Pangasius hypophthalmus) infected with Edwardsiella ictaluri bacteria using an incinerator with a certain temperature and time range was chosen because it can reduce the mass or volume of waste so that it cannot be reused. The aims of this study is to determine the mechanism of destruction of frozen catfish and obtain results of optimizing the process of destruction of frozen catfish infected with Edwardsiella ictaluri bacteria at a certain temperature and time range through burning. Bacterial contamination was carried out by revirulence through injection into the fish, then a burning test by destroying the catfish on a laboratory scale using a DTA machine. Based on the results of this trial, a burning test was carried out in an electric furnace which was carried out at a static temperature of 2000C and 4000C with a gradual time range. Next, destruction is carried out by burning in a fire furnace and a simple incinerator tube. The results of the DTA test analysis show that to burn catfish, a minimum temperature of 3500C is required for it to start burning itself, then it can continue to burn if the temperature can increase to above 4750C. Burning using an electric stove shows that heating at a temperature of 2000C can reduce the weight of fish from 350 grams to 50 grams for 120 minutes. When heated to a temperature of 4000C, catfish can burn naturally and the change in fish mass can become close to zero within 60 minutes. This shows that heating catfish at a temperature of 4000C can trigger the melting of fish fat and trigger natural combustion. The results of combustion using an electric furnace are used to design combustion using a fire furnace. It is hoped that this test will complete the understanding regarding the characteristics of burning catfish using a fire stove. Optimal burning and producing burnt ash kills E.ictaluri bacteria effectively. Overall, the burning process that has been carried out has been able to destroy the catfish. Electric furnaces with electrical energy, fire furnaces using gas burner lighters and incinerator tube furnaces using used oil lighters.
