One of the diseases that can be transmitted by flies is diarrhea. Green betel leaf contains essential oils, chavicol, arecoline, phenol, and tannins which function as plant-based insecticides. This study aimed to determine the effectiveness of green betel leaf extract (Piper betel) as a plant-based insecticide on the number of mortality of house flies (Musca domestica). The research was an experimental study used After Only Design used the One Way Anova test with a 95% confidence level. The samples used were 360 ​​house flies. Each treatment of 30 house flies with 4 repetitions and used three concentrations of green betel leaf extract (25%, 50%, 75%). The study was conducted at the Chemistry and Microbiology Laboratory of Health Polytechnic Tanjungpinang, while the location of the fly collection was at the Tokojo Garbage Collection Station in Bintan Regency. The number of mortality of house flies at a concentration of 25% was 81 heads (67.5%), 50% concentrations were 93 heads (77.5%), and at a concentration of 75% were 103 heads (85.83%). There was an effect of green betel leaf extract on the mortality of house flies (p-value 0.0001 <0.05) with the most effective concentration of 75%. Further research is needed to obtain a finished product utilizing green betel leaf extract as a vegetable insecticide, especially in controlling the fly vector. Need further research on the use of green betel leaf extract as a vegetable insecticide controlling the fly vector by taking into account the amount of spraying and the age of the fly.   Keywords: Green betel leaf extract , organic insecticide, houseflies

Abstract. The study of the efficacy of betel leaf extract (Piper betle L.) and garlic extract (Allium sativum) on the mortality of Aedes aegypti mosquito larvae was carried out at the Zoology Laboratory of the Faculty of Mathematics and Natural Sciences, Halu Oleo Kendari University. Aedes aegypti mosquito larvae were obtained from the rearing of F2 from Aedes aegypti eggs that were taken by ovitrap from in Kambu Village, Kendari City, which is an endemic area of Dengue Hemorrhagic Fever (DHF). Extrac of betel leaf (Piper betle L.) and garlic extract (Allium sativum) at concentrations of 1.0%, 2.0% and 3.0% respectively and their combinations were given to Aedes aegypti larvae (L4). The results showed that the highest larval mortality (88%) occurred after 24 hours of exposure to betel leaf extract (Piper betle L.) at a concentration of 3%, whereas with garlic extract (Allium sativum) the highest larval mortality (98%) occurred at concentration 3 %, and for the highest larval mortality (99%) found in a combination of 3% betel leaf extract (Piper betle L.) and 3% garlic extract (Allium sativum). Based on WHO (2009), the most effective treatment for killing Aedes aegyti larvae is 3% garlic (Allium sativum) extract and a combination of 3% betel leaf extract (Piper betle L.) and 3% garlic extract (Allium sativum).Keywords:  Biopesticide, Mortality, Aedes aegypti, betle leaf (Piper betle L.), garlic (Allium sativum).

<p>In Indonesia, strawberry is one of fruits which has high economic values. The growth of strawberry has increased significantly, but its productivity is still low because of disease attack. Disease that attacks strawberry started from nursery to post harvest is anthracnose that can be caused by Colletotrichum spp. Control efforts of anthracnose disease up to now has been done with application of synthetic chemicals which are known to be hazardous to the environment and human health. Betel leaf (Piper betle L.) is natural plant that potentially used as phytofungicide. Essential oils on betel leaf extract is reported can decrease the growth of pathogenic fungi. The objectives of the research were to identify Colletotrichum spp. in strawberry fruit that showed anthracnose symptoms, to test the potency of betel leaf extract as phytofungicide, and to evaluate the effect of betel leaf extract in inhibiting infection and disease severity of Colletotrichum in strawberry. Samples were taken from strawberry nursery in Magelang, Indonesia. The disease symptoms were isolated on Potato Dextrose Agar, followed by identification of fungal colony and morphology by semi permanent slide preparation. Betel leaves were extracted with water to get a concentration of 20, 40, 60, 80 and 100%, respectively. An in vitro experiment was done to evaluate the inhibition rate of betel leaf extract to the growth of Colletotrichum spp. colony. An in vivo experiment was done by submersion of strawberry to betel leaf extract before (preventive method) and after antrachnose attack (curative method), then disease infection and disease severity were measured after 7 days. The result of the research showed that anthracnose disease in strawberry was caused by C. gloeosporioides (Penz.). Twenty percent of betel leaf extract in an in vitro test had potential as phytofungicide and concentration of 100% betel leaf extract was the best concentration to inhibit the growth of C. gloeosporioides (Penz.) colony by 70.26±0,61%. In an in vivo experiment, submersion of strawberry before pathogen infection (preventive) with 100% betel leaf extract decreased disease infection by 40% and disease severity by 16%, respectively. While treatment of submersion of strawberry after pathogen infection (curative) decreased disease infection by 33,4% and disease severity by 17%. </p><p>Keywords: strawberry, anthrachnose, disease, betel leaf</p>

Nanoparticles are used in drug delivery which can increase mass transfer so increase the absorption and effectiveness of the drug. Therefore, its prospect to improve antibacterial and antioxidants activities of betel leaves. The research aimed to preparation and characterization of betel leaf extract using ionic gelation technique. The formulation of nanoparticles from betel leaf extract with ionic gelation method using alginate and CaCl2 with a ratio of 2.5: 1. The characterization of the nanoparticles includes particle size analysis, zeta potential, particle morphology and determination of flavonoid content. Particle size analysis demonstrated that the betel leaf extract nanoparticles had a particle size of 243,03 ± 1,48 nm, zeta potential of -23,0 ± 0,35 mV and morphology of particle showed that a flat shape. The betle leaf exctract nanoparticle positively contained flavonoid with Rf 0.7 equivalent to quercetin. The betel leaf extract can be made nanoparticles with ionic gelation method using alginate and CaCl2.
