Automated Food Preserving System Utilizing NodeMCU ESP8266-Based Drying Methodology
Get PDFFood drying is one of the effective methods for preserving food and extending its shelf life by inhibiting bacterial growth. In Indonesia, many food products require sun drying to preserve them. However, this process often disrupts due to sudden rain showers, which can impede the drying process. Therefore, a automatic food cover system is needed to facilitate human work and protect the drying process from rain disturbances. This study designs an apparatus that can automatically cover dried food using FC-37 rain sensor controlled by NodeMCU ESP8266. The device also features an email notification feature to provide information on whether it's raining or not, allowing users to take action before the rain arrives. With this automatic food cover system, we expect to improve efficiency and quality of food drying results

No full textLGBT behavior is a form of sexual deviance. Deviant sexual behavior in adolescents is caused by the way teenagers socialize freely and tends to be limitless, caused by the sexual urges that are developing in adolescents. Education about faith so far seems to have not been able to produce a generation that is steadfast, strong, and has high dedication to their religion. The method of implementing direct counseling is the method used in this community service activity. Counseling is carried out by visiting the location and providing materials related to Education on Preventing LGBT Acts in the Full Boarding Religious School Environment of Maahad Ahmadi Negeri Sembilan (SABP MANS) Malaysia. The results of the service show that the emergence of the LGBT phenomenon in schools is caused by various factors, such as lack of affection from parents, watching on social media, bad company, and having been a victim. Among the roles that the school can play include, first, providing socialization about LGBT. However, preventing LGBT students will not produce maximum results if it only relies on the school. Support and supervision from parents and the government are also very much needed, such as parental supervision of student viewing
Potensi Limbah Gulma Alang-alang dan Saliara sebagai Bioherbisida untuk Pengendalian Gulma secara Pra Tumbuh
Get PDFAlang-alang (Imperata cylindrica) and Saliara (Lantana camara) are dominant weeds in several crop cultivation areas, so that when control is carried out, waste from both weeds will be produced in large quantities. Management of waste from both weeds can be done by utilizing it as a more environmentally friendly bioherbicide. Bioherbicide application is carried out pre-growth so that control is carried out faster and attacks newly germinated weed seeds, so that weeds do not appear on the surface and weed control activities will be more efficient. Alang-alang is the most dangerous weed and is highly avoided because it contains allelochemical compounds that can inhibit the growth of the main plant, this compound is found in all parts of the weed but is found most in the roots. Saliara also has a high content of allelochemical compounds which causes a distinctive aroma from its leaves. The allelochemical content of both weeds can be used as active ingredients in bioherbicides and is effective in controlling other weed species. Several studies have reported that bioherbicide extracts from both weeds are effective in inhibiting weed growth so that they can be used as an alternative to herbicides. However, bioherbicide application must be carried out with the right technique and concentration so as not to interfere with and inhibit the growth of the main plant
