Abstract/Executive Summary

This research investigates the larvicidal potential of Caulerpa lentillifera, commonly known as sea grapes. Specifically, it aims to determine whether 0%, 10%, 20%, or 30% concentrations of C. lentillifera extract can significantly increase mosquito larval mortality after four hours of exposure. The experiment followed standardized guidelines established by the World Health Organization (WHO), and larval mortality was calculated using Abbott’s formula. This research investigates the larvicidal potential of C. lentillifera, commonly known as lato sea grapes. Specifically, it aims to determine whether 0%, 10%, 20%, or 30% concentrations of C. lentillifera extract can significantly increase mosquito larval mortality after four hours of exposure. Prior research by Mariam et al. (2021) on larvicides was also referenced. An experimental approach was employed, and data were analyzed using Analysis of Variance (ANOVA) to determine significant differences among concentrations. Results indicated that 20% was the most optimal concentration; although 30% had the highest mean mortality rate, the lack of statistically significant difference between 20% and 30% suggests that 20% is sufficient to achieve effective results while conserving resources. Ethical standards were strictly observed throughout the research, including safe laboratory practices, proper waste disposal, and responsible data management in accordance with relevant regulations. AI tools such as ChatGPT, Quillbot, and Grammarly were used exclusively for organizing and refining the language, without affecting data validity. These findings suggest that C. lentillifera has potential as a biocide-free mosquito larvicide, offering a sustainable alternative to conventional chemical repellents.
