Abstract

The primary carrier of the dengue virus-caused disease dengue hemorrhagic fever is the Aedes aegypti mosquito.By eliminating the flick using larvacides, the effort of seeding can be avoided. Tannin concentration in lime leaf extract (Citrus aurantifolia) is known to suppress the growth of larval cuticles. The objective of the study was to assess how C.aurantifolia lime leaf extract affected the development of Ae. aegypti larvae. This form of research is experimental, and this extract is produced by macerating lime leaves in 90% ethanol before extracting it via evaporation. The study included four groups: aquades used as a negative control for testing on larvae and concentrations of 12.5%, 25%, and 50% lime leaf extract. Testing and observations have been conducted for 24 hours. The findings showed that different concentrations of lime leaf ethanol extract (C. aurantifolia), which is 100% poisonous to Ae. aegypti larvae, can impede its growth. To conclude, biolarvasida can be created by using the lime leaf extract. No morphological modifications were made to the Ae. aegypti larvae used in this investigation.

Abstract

Bird diversity in an area is one of the guidelines in the management of biological resources. Birds play an important role in controlling insect populations, helping with pollination and seed dispersal. This study aims to identify the types of birds in the order Coraciiformes and identify their level of diversity in the CRU Sampoiniet forest area, Aceh Jaya. The method used in this study is the Point Count method with 10 observation points for each point. Then it is calculated with a duration of 15 minutes with a radius of 50 meters and a distance of 200 meters for each point. Data analysis used a bird species identification book and used the Shannon Winner diversity formula Ĥ = ∑ Pi Ln Pi. The results of the research on the diversity of species of aves the order Coraciiformes in the CRU (Conservation Response Unit) Forest Area of ​​Sampoiniet Aceh Jaya, consisted of 7 species from 3 families with a total of 33 individuals. The overall diversity index of species of aves of the order Coraciiformes Ĥ=1,89218, so the species diversity of aves of the order Coraciiformes in the Sampoiniet Aceh Jaya CRU (Conservation Response Unit) Forest Area categorized in the low diversity index.
