Fruits are included in foodstuffs that provide many benefits for the body, but fruits have a relatively short shelf life. ELF (Extremely Low Frequency) magnetic field radiation is radiation with a low frequency of around 0–300 Hz with non-ionizing properties or no effect on the atoms of a material it is subjected to and non-thermal or does not cause an increase in temperature when interacting with a material. In addition, Extremely Low Frequency (ELF) magnetic field radiation can be used for food tenacity. This study aims to determine how much influence ELF radiation has on the shelf life of various types of fruits. The method used in this study is the journal review method, the number of journals reviewed is 11 journals. The journal in question can be in the form of scientific articles and other journals that support and are relevant to the research title. The results of this study indicate that exposure to the ELF magnetic field can maintain the content of vitamin C, maintain the physical condition of the fruits, and increase the shelf life of fruits by maintaining pH by slowing down or increasing the pH, this is done by killing acid-forming microorganisms, In addition, exposure to the ELF magnetic field can reduce the respiration rate and the rate of ethylene production in fruits, this has an impact on extending the shelf life of fruits. The intensity and duration of exposure to the ELF magnetic field must be adjusted to the type and character of the fruit itself. Thus, it can be concluded that exposure to Extremely Low Frequency (ELF) magnetic fields are able to maintain vitamin C content, maintain the physical condition of fruits, and increase the shelf life of fruits.

The problems that are often encountered are the problem of garbage or waste from human activities, these activities include households, agriculture, factories, and others. The purpose of this research is to reduce waste or waste that is really needed at this time whether it is used for other alternative sources that are environmentally friendly, so that waste or waste from agricultural activities does not continue to increase, organic fertilizer and briquettes or charcoal can be used. In this study using the method of literature review from various international journals. The journal used starts from the past 10 years, namely 2012-2022 and searches for it via Google Scolar. Keywords used when searching journals on Google Scolar such as "agricultural waste processing", "briquette management", and "agricultural waste". Garbage is the remains of human activities that are not reused but can produce a useful new product. There are various types of waste or waste, one of which is agricultural waste which can produce products that are beneficial to the environment or environmentally friendly. Agricultural waste is the part of agricultural plants from the top or shoots to the remaining stems after harvesting activities. Utilization of agricultural waste is very useful for humans, the environment, and other living things. One of the uses of this agricultural waste is as briquettes which are a new alternative source that is environmentally friendly because it comes from various plant residues produced during harvesting activities. Most of the agricultural waste comes from rice. So, the existence of agricultural waste can be used as a new alternative source that is environmentally friendly and inexpensive.

Garbage is used goods obtained from human and natural activities that have no economic value. Until now, waste is still an unresolved problem, one of which is in Indonesia. Patchwork is the remnants of cutouts from fabric-making or convection businesses. The abundance of patchwork potential is not proportional to the processing carried out. The tailors or workers on average do not know the importance of patchwork processing so the patchwork is discarded without being reprocessed. This problem also occurs in Bandung Village. The high level of use of plastic waste can be minimized by utilizing the potential of patchwork through shopping bags made of patchwork (Patchwork Bag). The purpose of this study was to provide education about the importance of making shopping bags made of patchwork and to improve the skills of women in making shopping bags made of patchwork. The research method used is a qualitative description. The results showed that the women in Bandung Village were very happy with the training activities to make shopping bags made of patchwork. This can provide additional insight, improve skills, and can be used for entrepreneurs.

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.
