Vegetable insecticide is a natural material that is environmentally friendly. This material can be used in the prevention and control of mosquito larvae, especially Culex sp. Culex sp is the main vector of filariasis disease and dengue hemorrhagic fever (DHF). Use of natural materials is very good and environment friendly as insectcide compared with chemicals. Avocado seed extract (Persea americana Mill) is known to have secondary metabolite content of alkaloids, saponins, triterpenoids while soursop extract (Annona muricata L) in the form of acetogenin, squamocin and annonacin. This research needs to use of avocado seed extract (P. americana Mill) and soursop seed extract (A. muricata L) as larvacide of Culex sp. The aim of this research is to know the effect of avocado seed extract (P. americana Mill) and soursop seed extract (A. muricata L) to mortality of Culex sp Instar III mosquito larvae and LC50 for 24 hours. This study was an experimental study using a complete randomized design (RAL) with five treatment concentrations (0, 2, 4, 6, and 8%) avocado seed extract (P. americana Mill) and soursop extracts extract (A. muricata L) as much as five repetitions. The data obtained were analyzed by using One Way ANOVA to show the effect on the treatment. The results showed that giving of avocado seed extract (P. americana Mill) with 8% concentration (23,8 ± 0,45 larvae) was optimal in killing Culex sp mosquito larvae. While giving soursop seed extract (A. muricata L) with 4% concentration (25 ± 0,0 larva) optimal in killing Culex sp mosquito larvae. Avocado seed extract (P. americana Mill) has an effect as a larvacide against Culex sp. instar III with LC50 at concentration 2,486% while soursop extract (A. muricata L) with LC50 value at concentration 1,605%.

Abstract

The use of chemical larvicides to control mosquito larvae in water reservoirs has a negative impact, causing environmental pollution and resistance to target organisms. The alternative to reduce this impact is using vegetable larvacides from Rambutan Seeds (Nephelium Lappaceum L) and Mango Seeds (Mangifera indica L). This study aims to determine the effectiveness of Rambutan Seed Extract (Nephelium Lappaceum L) and Mango Seed Extract (Mangifera indica L) on the mortality of Aedes aegypti larvae after being treated for 24 hours. This type of research is experimental with a pure experimental study design (true experiment). The treatment concentration given for 24 hours was 0, 2%, 4%, 6%, 8% of each extract with 5 replications. The samples in the study were III instar Aedes aegypti larvae totaling 800 heads. Data analysis was performed by Anova test and probit test. Based on the results of research on rambutan seed extract (Nephelium lappaceum L) LC50 value of 3.190% was more effective against mortality of Aedes aegypti larvae than Mango seed extract (Mangifera indica L) LC50 value of 4.758%.

Abstract

Mangrove ecosystems play an important role in the life cycle of various types of fish, shrimp and crabs. Because the mangrove environment provides protection and nutrients in the form of organic matter that is included in the food chain. Some of the fauna that are commonly found in the Indonesian mangrove ecosystem area are fauna from the gastropod, crustacean, bivalve, polychaeta, and pisces classes. One of the biota that can be used as biological parameters in determining the conditions of a body of water is macrozoobentos. As organisms living in waters, macrozoobentos are very sensitive to changes in the quality of the water in which they live so that it will affect their composition and abundance. This research method is quantitative descriptive research by taking data in a survey. It uses a 1x1m measuring plot 100m long perpendicular to the coastline. The measurement method used to determine the environmental conditions of mangroves is the transect line method and sample plots (Tran-sect Line Plot). The diversity index value at research locations I and II is in the medium category, while in location III it is in the high category. Of the three stations, the uniformity index is stable close to 1. Result The dominance index value is that there is no type that dominates a body of water, this means that all individuals at the observation station have the same opportunity and maximally make the most of the resources in those waters. The pH results of water at station II and station III did not differ significantly, while at station I it differed significantly when compared to the results at stations II and III. The salinity results at station III differ significantly from station I and II because the location of the mangrove is the location of a sea estuary that makes the salt content of brackish water mixed with fresh water.    Keywords ; Mangroves, Macrozoobentos, Diversity, Uniformity, Dominance, Abundance, Abiotic Factors
