Analysis of Extremely Low Frequency (ELF) Magnetic Field Effect to Oyster Mushroom Productivity

Abstract

Extremely Low Frequency magnetic field has frequency 0-300 Hz and included on non-ionizing radiation. The side effect of ELF magnetic field researched by many researcher on some sectors, such as on food sector and agriculture sector. In food sector, research of Sudarti (2016) shown that ELF magnetic field can use as alternative sterilization gado-gado food to decrease population of Salmonella. Oyster mushroom as alternative nutrition sources with many advantages for health, many people consume it and start cultivation it. ELF magnetic field can use as growth accelerator in agriculture sector, such as for oyster mushroom growth. This research aims to analyze of effect of ELF magnetic field to oyster mushroom productivity based on appearance of pin head and oyster mushroom wet weight. Result shown that exposure ELF magnetic field with intensity 500 µT in 50 minutes influence appearance of pin head with average amount 20,2 and influence oyster mushroom wet weight amount 212,2 grams.
