Paparan electric liquid vaporizer ekstrak daun salam terhadap durasi kematian nyamuk Aedes aegypti

Introduction

Paparan electric liquid vaporizer ekstrak daun salam terhadap durasi kematian nyamuk aedes aegypti. Uji efek ekstrak daun salam (Syzygium polyanthum) dalam electric liquid vaporizer pada kematian nyamuk Aedes aegypti penyebab DBD. Konsentrasi 80ml efektif membunuh 60% nyamuk dalam 30 menit.

Abstract

Insidensi DBD di Indonesia dalam 50 tahun terakhir mengalami peningkatan dengan pola siklus puncak tiap 6-8 tahun. Fokus pengendalian vektor pada upaya kimiawi mengakibatkan resistensi nyamuk di sejumlah daerah sehingga perlu upaya biologis sederhana yang ramah lingkungan dengan memanfaatkan daun salam sebagai obat nyamuk cair elektrik. Penelitian ini bertujuan untuk mengetahui paparan electric liquid vaporizer ekstrak daun salam (Syzygium polyanthum) terhadap durasi kematian nyamuk Aedes aegypti. Penelitian menggunakan sampel 150 ekor nyamuk dewasa yang dibagi dalam 5 perlakuan (kontrol, 20ml, 40 ml, 60 ml, dan 80ml) dan 3 kali pengulangan selama 30 menit durasi pengamatan. Hasil penelitian menunjukkan efek tertinggi dalam membunuh 60% nyamuk Ae. aegypti terjadi pada durasi paparan 30 menit electric liquid vaporizer ekstrak daun salam (Syzygium polyanthum) di konsentrasi 80 ml. Sementara durasi paparan 10 menit tidak memberikan efek apapun bagi nyamuk. Besar konsentrasi uap dari ekstrak terhadap mortalitas nyamuk secara berurutan adalah 80 ml, 60 ml, 40 ml dan 20 ml mengakibatkan kematian 60%, 46,6%, 13,3%, dan 30%. Bagaimanapun penggunaan alat electric liquid vaporizer memiliki keuntungan dan kerugian yang harus diwaspadai. Disarankan untuk studi lanjutan pengendalian vektor antar jenis electric vaporizer, variasi dosis dan jenis tanaman.

Review

This study addresses a pertinent public health issue by exploring a natural, environmentally friendly alternative for controlling *Aedes aegypti*, the primary vector of dengue fever. Given the increasing insecticide resistance, investigating botanical extracts like *Syzygium polyanthum* (daun salam) as an active ingredient in electric liquid vaporizers is a commendable effort. The research aims to determine the effect of *S. polyanthum* extract exposure via an electric liquid vaporizer on the mortality of *Aedes aegypti* mosquitoes, thereby contributing to the development of sustainable vector control strategies in areas frequently affected by dengue outbreaks. The methodology involved exposing 150 adult mosquitoes to five different treatments (control, 20ml, 40ml, 60ml, and 80ml concentrations of the extract) for 30 minutes, with three replications. The findings indicate a dose-dependent effect, with the highest mortality rate of 60% observed at the 80ml concentration after 30 minutes of exposure. Interestingly, a 10-minute exposure duration yielded no effect, highlighting the importance of sufficient contact time. The reported mortality rates for increasing concentrations (80ml, 60ml, 40ml, and 20ml) were 60%, 46.6%, 13.3%, and 30% respectively. The authors also acknowledge both advantages and disadvantages associated with the use of electric liquid vaporizers, emphasizing the need for cautious application and further investigation. While the study presents a promising direction for eco-friendly vector control, several aspects could enhance its rigor and clarity. Firstly, the title mentions "durasi kematian" (duration of death), but the abstract reports "mortalitas" (mortality percentage) at fixed exposure durations; clarifying whether the time-to-death was measured or just end-point mortality would be beneficial. Secondly, the dose-response trend presented for 20ml (30% mortality) being higher than 40ml (13.3% mortality) appears inconsistent and warrants further explanation or re-evaluation. Additionally, the absence of reported statistical analysis makes it difficult to ascertain the significance of the observed differences between treatments. Future research should also consider identifying the active compounds responsible for the observed insecticidal effect, comparing the efficacy against a standard chemical repellent, and extending the observation period beyond 30 minutes to capture potential delayed mortality, as suggested by the authors' recommendations for exploring different vaporizer types, varying doses, and plant species.
