Abstract

Coffee production in Sidomulyo Village, located at the foot of Mount Gumitir, Silo District, Jember Regency, is famous for being very abundant. This condition is very supportive of the increasing needs of coffee drink lovers. However, the taste of ready-to-brewed ground coffee produced by the Sidomulyo Koperasi WANITA is still unable to compete with coffee on the market. This activity aimed to provide training on civet coffee production through the dry coffee bean fermentation method as a primary ingredient. The fermentation process was carried out using a Magnetic Fermentation machine which was the result of research in 2020. The fermentation process training activity was attended by 15 members of the Koperasi WANITA. 50 kg of dry coffee was fermented using a Magnetic Fermenter machine. Dry coffee was soaked first in warm water (temperature around 30 - 400C) for 5 hours. Then it was drained and put in a fermenter box by adjusting the intensity of the ELF magnetic field to around 300 T for 90 minutes. The coffee beans were transferred to buckets and ripened for up to 5 days, then washed and sun-dried for three days, after drying in Roasting and continue grinding. The targeted outputs of this activity included scientific publications in the National Journal of Abdimas with ISSN. The results of this activity had produced fermented coffee beans that had been roasted in the form of roasted coffee beans and ground coffee. Based on the results of the evaluation, the members of the Ketakasi Koperasi already had skills in producing artificial Luwak coffee. This had the potential to develop superior products for Sidomulyo civet coffee.

Abstract

The current study is based on the needs of human life that cannot be separated from the role of electricity. This is why the demand for electricity is getting increased, so it requires the construction of transmission channels, one of them is SUTT. Without realizing it, the channel emits magnetic field. The exposure to magnetic field generated by SUTT has extremely low frequency since the rate commonly used in Indonesia is 50 Hz. The purpose of the current study was to find out the distribution pattern of magnetic field radiation intensity below SUTT 150 kV and the influence of roof types to the decrease of ELF magnetic field intensity by SUTT 150 kV. The study design was field experiment using measuring devices of magnetic field with EMF-827. The results confirmed that the area under the phase wires had the greatest magnetic field intensity, that was almost 70 times bigger than that of the natural magnetic field intensity. Based on the data collection, the use of roof barrier did not effect to the decrease of the magnetic field intensity because the decrease had segnificantly occured at farther distance from the phase wires without using roof barriers. All the results of magnetic field intensity measurements was still below the limit allowed by WHO. The results of the current study can be used as new understanding for Indonesians, especially those who still live under the transmission line
