Description
Summary:Extremely Low Frequency (ELF) magnetic field research is starting to develop towards its utilization. The effects of cell proliferation or cell apoptosis by exposure to ELF magnetic fields can be used as a basis for developing useful technologies in the future. It has been reported that exposure to the ELF magnetic field with an intensity of 300 µT is able to optimize the fermentation process to improve the taste of coffee. Exposure to an intensity of 500 µT was able to increase the resistance of vannamei shrimp, and at an intensity of 1000 µT it has the potential to be developed for tumor therapy technology. However, until now the certainty of an effective dose and the underlying mechanism is still unclear. This study aims to explainthe mechanism of inhibition of Enterobacter Aerogenes proliferation and its effect on the physical resistance of tuna (Eutynnusaffinis C) exposed to ELF magnetic fields of intensity of 700 uT and 1000 uT. This study used a completely randomized design (CRD) with a sample of 2,100 grams of fresh tuna meat. The sample was divided into 7 groups, namely the control group (K),the group exposed to the ELF magnetic field intensity of 700 uT (E_700) and 1000 uT (E_1000) for 15 minutes, 30 minutes and 45 minutes respectively. Furthermore, monitoring of the pH and physical condition of the tuna meat before being exposed (0 hour), 5th hour, 10th hour, and 15th hour after being exposed to the ELF magnetic field. Observation of Enterobacter Aerogenes population was carried out at 15 hours after exposure. The results showed that the pH value of tuna meat exposed to the ELF magnetic field was significantly (p
