Akan tetapi, kemampuan G. lucidum dalam menghambat tukak lambung yang disebabkan H. pylori belum banyak diungkap. Penelitian ini bertujuan untuk mengetahui efektivitas ekstrak G. lucidum dalam menghambat pertumbuhan H. pylori penyebab tukak lambung. Penelitian merupakan ekperimental dua faktorial yaitu jenis pelarut fraksinasi dan konsentrasi ektrak G. lucidum. Ekstrak G. lucidum difraksinasi menggunakan dua jenis pelarut yaitu etanol 60% dan akuades. Konsentrasi ekstrak G. lucidum yang digunakan adalah 1, 5, 10, 20, 30 mg/mL. Efektivitas ekstrak G. lucidum diuji dengan metode difusi cakram. Berdasarkan analisis statistik didapat bahwa jenis pelarut berpengaruh terhadap aktivitas daya hambat H. pylori dengan nilai pada pelarut etanol 60% signifikan lebih tinggi dibandingkan akuades. Konsentrasi ekstrak G. lucidum baik etanol maupun akuades berpengaruh signifikan terhadap aktivitas daya hambat.

Helicobacter pylori is known to be the main cause of gastric ulcers by weakening the protective lining of the stomach and duodenal. A number of gastric anti-ulcer drugs can cause resistance to H. pylori. Ganoderma lucidum is known to inhibit and support the healing of gastric ulcers caused by acetic acid. G. lucidum's ability to inhibit H. pylori growth has not been revealed much. This research aims to find out the effectiveness of G. lucidum extract in inhibiting the growth of H. pylori which causes gastric ulcers. This study is an experimental two factorial namely the type of fractionation solvent and the concentration of G. lucidum extract. Ganoderma lucidum extract is diffractionated using two types of solvents namely 60% ethanol and akuades. The concentration of G. lucidum extract used is 1, 5, 10, 20, 30 mg/mL. The effectiveness of G. lucidum is tested using the disc diffusion method. Based on statistical analysis found that the type of solvent affects the activity of H. pylori's resistance with a value in ethanol solvents 60% significantly higher than akuades On the other hand the concentration of G. lucidum extract in both ethanol and aquades has a significant effect on the activity of the slave.
