Ecoenzymes are natural ingredients formed from the fermentation of fruit and or vegetable residues that have many benefits. One of the benefits of ecoenzymes is that they can be used as eco-handsanitizers; which can be used as a candidate for handsanitizer for those who are allergic to alcohol-based handsanitizer. This study aims to determine the pH, antibacterial, antiviral, and antifungal content of the candidate eco-handsanitizer solution through alkaloid, flavonoid, and saponin test, also fungal-inhibition test. The candidate eco-handsanitizer solution was made from an ecoenzyme solution derived from fruit or vegetable residue and added with aloe vera gel and vitamin C or E. The results showed that eco-handsanitizer candidate solution derived from ecoenzyme solution with a dilution of 1:500 or 1:4 and added with aloe vera and vitamin E had a pH that tends to be acidic after 5 weeks of manufacture. The candidate eco-handsanitizer solution contained alkaloid compounds up to 2nd week for 1:500 dilution or up to 5th week for 1:4. Fungal test also showed positive results of one of the treatments in inhibiting fungal growth until the 11th day. These results were expected to be used as guidelines for further research, such as quantitative and qualitative tests for more sensitive alkaloids, for example using GC-MS.ÃÂ
Long bean (Vigna sinesis L.) is a horticultural plant that is easy to cultivate. Cultivation of long bean plants certainly has several factors that can reduce production yields such as environmental factors, pest attacks, and diseases. This study aims to determine the pests and diseases that generally attack long bean plants and the symptoms they cause. This study used direct observation method (Systematic sampling) to determine the percentage of pest and disease attacks on long bean plants. From the total number of plants in the location, 5 plant samples were taken to be observed. Based on the pest and disease identification research that has been carried out, it was found that some of the symptoms that arise due to pest/disease attacks on most of the long bean plants were found. Symptoms that appear include damage to flower buds and leaves with holes caused by black ladybugs (Brachyplatys sp.); leaf curl, leaves and stems turn black due to aphids (Aphis craccivora); jagged leaf edges, and holes caused by grasshoppers (Oxya sp.) and lasiocampidae caterpillars; thickening of the leaf veins on young leaves, leaves shrinking caused by Bean Common Mosaic Virus (BCMV); The leaves turn yellow and the bone blanching occurs due to the Mungbean Yellow Mosaic Virus (MYMV).
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.
