The Effectiveness of Mexican Ageratum (Ageratum conyzoides) Leaf Solution in Reducing Fly Density at Waste Collection Sites in Banjarbaru

Fly infestations at waste collection locations present considerable public health hazards, requiring efficient and environmentally sustainable treatment strategies. This research examined the effectiveness of Mexican Ageratum (Ageratum conyzoides) leaf solution in diminishing fly populations at temporary garbage collection sites (TPS) in Banjarbaru, Indonesia. Employing a quasi-experimental methodology with a Posttest Only Control Group design, we evaluated three concentrations (55%, 60%, and 65%) of the solution in comparison to a control group. Fly density was assessed utilizing the fly grill method, while environmental variables were continuously observed during the experiment. The Kruskal-Wallis test was utilized for statistical analysis. The results indicated a substantial decrease in fly density at all concentrations, with the 65% solution demonstrating the most efficacy, resulting in an 89% reduction (from an average of 25.5 to 3.0 landings). Although this did not completely satisfy the legal criterion of fewer than two landings, it signifies a considerable enhancement. The research validates the efficacy of Mexican Ageratum leaf solution as a sustainable substitute for synthetic insecticides in waste management contexts; nevertheless, additional studies are required to enhance its effectiveness and evaluate its long-term environmental consequences.
