Potency of Active Compound of Red Galangal (Alpinia Purpurata K. Schum) in Killing Anopheles Sp. Larvae

Malaria is an infectious disease caused by the Plasmodium parasite, which is transmitted to humans through the bite of the Anopheles sp. From 2009-2015 malaria included Extraordinary Events (KLB) always occurring on the island of Borneo Red galangal rhizomes contain active compounds that can make larvae of Anopheles sp. this research method is an experiment (experiment). To determine the lowest concentration of red galangal, a concentration of 8 mg / mL, 4 mg / mL, 2 mg / mL, 1 mg / mL, and 0.5 mg / mL was carried out. The results of the research data were analyzed by one way Analysis of Varians (ANOVA). Larvicidal activity of red galangal extract is a concentration of 0.5 mg / mL with larvae mortality of 8 larvae, concentration of 1 mg / mL with 9 larvae deaths, concentration of 2 mg / mL larvae mortality of 14 animals, concentration of 4 mg / mL with larval deaths were 22 larvae, and at a concentration of 8 mg / mL larval deaths were 25 larvae. The Red galangal extract (Alpinia purpurata K. Schum) has an active larvacide compound that has the potential as an antimalarial due to Anopheles sp.
