Pengendalian vektor malaria masih ditekankan pada penggunaan insektisida kimia.
Penggunaan insektisida kimia yang berulang-ulang dapat mengakibatkan resistensi vektor,
matinya hewan lain yang bukan sasaran dan pencemaran lingkungan. Oleh karena itu dicari
cara lain yaitu dengan menggunakan insektisida hayati salah satunya adalah dengan
menggunakan tanaman sirsak (A. muricata L.) yang mempunyai kandungan senyawa aktif
annonain, tanin, alkaloid. Penelitian ini bertujuan untuk menguji apakah ektrak akar sirsak
(A. muricata L.) dapat menyebabkan kematian larva Anopheles aconitus. Metode penelitian
ini menggunakan rancangan eksperimen dengan desain "Post test only control group design".
Pada konsentrasi terendah (0,01%) menyebabkan kematian larva An. aconitus sebesar 8,35%
dan pada konsentrasi tertinggi (0,4%) semua larva An.aconitus mati. Hasil uji Anava
menyatakan bahwa terdapat perbedaan rata-rata kematian larva pada berbagai tingkat
konsentrasi ekstrak akar sirsak (A.muricata L.) Uji LSD (Least Significant Different)
menunjukkan bahwa tidak semua pasangan nilai rata-rata kematian larva An. aconitus
berbeda secara signifikan. Kesimpulan ekstrak akar sirsak (Annona muricata Linn) dapat
membunuh larva An.aconitus, konsentrasi yang dapat memeatikan larva An.acnitus pada LC
50 sebesar 0,15% dan LC 90 sebesar 0,27%, ada perbedaan rata-rata kematian larva
An.aconitus pada berbagai tingkat konsentrasi ekstrak akar sirsak (A. muricata L.) secara
signifikan (p<0,05).

THE EFFEECT OF GIVING SOURSOP ROOT EXTRACT
TO THE DEATH OF Anopheles aconitus LARVAE.
Abstract
The control of malaria vector is still emphasized on the usage of chemical insecticides, which
repeatedly can cause vector resistance, death of other animals which is not target and
population. Therefore, it must be looked for other way to control malaria vector that is by
using natural insecticide, one of them is by using soursop plant (A. muricata L.) which have
active compound containing annonain, tanin and alkaloid. This research is intented to do a
test whether soursop root extract (A. muricata L.) Can cause death of Anopheles aconitus
larvae. This research method is using experimental plan with "Post test only group design".
The result shows that there are death of An. aconitus larva after giving of soursop root
extract (A. muricata L.) The lowest concentration (0,01%) cause deathof An. aconitus larva
8,35% and the highest concentration (0,4%) all An.aconitus larva are dead. Result of Anava
test expresed that there are differences of the averase of larva death at various extract
concentrations level of soursop root extract (A. muricata L.) The LSD (Least Significant
Differences of the averase of larva death at various extract concentrations level of soursop
root extrct ( A.muricata L.) The LSD (Least Significant Different) test indicate that not all
couple average of value death of An. aconitus larvae are different significantly. The
conclusion of this research is the soursop root extract (A.muricata L.) can kill An. aconitus
larva. The concentration that is able to kill An.aconitus of the averase of larva's An. Aconitus
death at various extract concentration of soursop root extract (A.muricata L.)
