Nanoemulsion is one of the nanotechnology applications that can measure particles 0-100 nm which has control of the release of active ingredients and good sensory properties. Nanoemulsion of ethanol leaf extract in various plants has considerable potential in the utilization of natural materials. The solvent used is an important factor. This research focuses on plant leaf parts with ethanol extract. The purpose of this review is to study, evaluate and analyze literature focused on the characteristics of nanoemulsion preparations of ethanol leaf extracts in various plants related to nanoemulsion components, manufacturing methods, and nanoemulsion preparation characteristics. This research uses the method of literature review or narrative review, the search for published scientific literature is indexed in various databases. Search articles through various databases to ensure that the majority of relevant studies have been identified. Based on the results of the literature review concluded that the most widely used surfactant in the review of these articles is Polysorbat 80 or Tween 80 which is a non-ionic and non-irritative surfactant commonly used in pharmaceutical and cosmetic preparations. Ultrasonification and microfluidation methods are also applied in some articles because they are capable of producing a minimum droplet diameter of 150 to 170 nm..The results of the study of particle size in the article produced particle sizes between 10.9 nm-312.1 nm. Indeks polidispersitas value 0.08-0.7 zeta potential value above +/-30 and EE value shows value above 80%. It can be concluded that the nanoemulsion characteristics of each article meet the requirements and produce stable nanoemulsions.
Efforts to improve a healthy lifestyle are very important, one of them is to stop smoking. The way to stop smoking can be through acupressure complementary therapy training and counseling on smoking health risks. The purpose of this activity is to increase public awareness and knowledge regarding the smoking health risks and acupressure therapy in order to reduce the desire to smoke for residents in the Bandung Village, Mertoyudan District, Magelang Regency. This activity involves the participation of the local community so that they can realize the importance of reducing smoking habits and the impact of smoking. The method used was counseling on the smoking health risks and acupressure training. The results of the activity showed that the residents were enthusiastic in participating in the activity and were able to apply acupressure therapy in their daily lives to stop smoking.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
