Synthesis of silver nanoparticles using tembesu bark extract (Fagraea fragrans) and antifungal tests on fungi that infected mango plants have been carried out. Making AgNPs through variations in the volume of the tembesu bark extract and temperature, the best volume of tembesu bark extract whichwas 5 mL and the best temperatureof AgNPs is at 70oC. The results of the analysis FTIR on tembesu bar…
