The Extraction of Zingiber Officinale Rosc as a Natural Insecticide for Aedes Aegypti Larvae

Abstract

Dengue fever is a health problem in Indonesia, including in Gorontalo Province, with an incidence rate of 101.53 per 100,000 population. One of the efforts to prevent the incidence of dengue fever is the use of natural insecticides, including red ginger. This study aims to assess the effectiveness of red ginger juice on the mortality of Aedes aegypti mosquito larvae. This research took place at the Laboratory of the Department of Public Health, the State University of Gorontalo, in 2021 using a True Experiment design. The mosquito larvae samples used were 500 larvae of Aedes aegypti instar IV mosquitoes taken from endemic areas of dengue fever in Gorontalo. Data were analyzed using the One Way ANOVA statistical test. Red ginger extract was given in five concentrations, namely 60%, 70%, 80%, 90%, and 100%. The results showed an effect of red ginger extract on the mortality of Aedes aegypti mosquito larvae at each treatment concentration given (p-Value = 0.000). The higher the concentration level given, the higher the larval mortality rate will also be. Red ginger is expected to be used by the community to prevent dengue fever.

Perbandingan Manifestasi Klinis Penderita Demam Berdarah

“…Pemerintah terus berusaha menurunkan angka kejadian kasus DBD dengan berbagai kegiatan seperti program promosi pemberantasan sarang nyamuk, penyuluhan kesehatan, pembentukan tim jumantik, pemberian bubuk abate serta fogging. Namun jika masyarakat tidak ikut berperan aktif untuk membersihkan lingkungan sekitar sulit untuk menurunkan angka kejadian kasus DBD ini [14] [15]. World Health Organazation (WHO) tahun 2019 menetapkan bahwa diagnosa klinis berupa tanda dan gejala DBD pada anak adalah ruam makulopapular pada tubuh dan demam yang tidak terlalu tinggi, namun pada orang dewasa sering terlihat disertai gejala lain seperti sakit kepala, mual, muntah dan sakit mata [16].…”

The potential of ginger (Zingiber officinale Rosc.) extracts as a bio-pesticide

“…The pungent scent, aroma, and flavor of ginger are attributed to a combination of volatile oils such as gingerols and shogaols [12] . Ginger has advantageous characteristics that help battle plant disease [13] symptoms and works as insecticidal [14] , aphicidal [15] , ovicidal, and antifeedant [16] on pest populations. Active compounds like gingerol, zingiberene, and shogaol in ginger influence insect metabolic processes, including chitin synthesis, respiratory systems, central nervous systems [17] , sexual communication, shrinkage of larvae [16] , and ultimately insect death.…”
