Telah dilakukan penelitian tentang uji aktivitas larvasida aedes aegypti ekstrak metanol daun pandan laut pandanus tectorius pada bulan februari - juli 2024 di laboratorium kimia laut dan bioteknologi perikanan, universitas syiah kuala. penelitian ini bertujuan untuk menentukan kandungan senyawa metabolit sekunder dan nilai lc50 uji larvasida aedes aegypti ekstrak metanol daun pandan laut pandanus tectorius. terdapat 5 jenis senyawa metabolit sekunder yang didapatkan dari ekstrak metanol daun pandan laut pandanus tectorius antara lain alkaloid, flavonoid, steroid, saponin, dan tanin. hasil uji toksisitas terhadap larva aedes aegypti dilakukan dengan perbandingan konsentrasi 1000 ppm, 500 ppm, 250 ppm, 100 ppm dan kontrol positif. hasil uji menunjukkan bahwa ekstrak daun pandan laut pandanus tectorius memiliki tingkat toksisitas dengan kategori toksik yaitu lc50 yaitu 314,430 ppm. kata kunci : pandan laut pandanus tectorius, metabolit sekunder, larvasida, aedes aegypti, lc50.

Research on the larvicidal activity of Aedes aegypti methanol extract of Pandanus tectorius leaf was conducted from February to July 2024 at the Marine Chemistry and Fisheries Biotechnology Laboratory, Syiah Kuala University. This study aims to determine the content of secondary metabolite compounds and LC50 value of Aedes aegypti larvicidal test of methanol extract of Pandanus tectorius leaf. There are 5 types of secondary metabolite compounds obtained from the methanol extract of Pandanus tectorius leaf, including alkaloids, flavonoids, steroids, saponins, and tannins. The results of toxicity tests against Aedes aegypti larvae were carried out with a concentration ratio of 1000 ppm, 500 ppm, 250 ppm, 100 ppm and positive control. The test results show that Pandanus tectorius pandan laut leaf extract has a toxicity level with a toxic category, namely LC50 which is 314.430 ppm.
