“…Fase lag pada Escherichia coli dan Staphilococcus aureus tidak tampak, mungkin terjadi pada jam ke 0 hingga jam ke 3. hal ini terjadi dikarenakan bakteri tersebut tumbuh pada media yang sama dengan media pada saat pembuatan inokulum sehingga penyesuaian diri dengan lingkungan yang baru berlangsung cepat. Menurut [27][28][29] menyatakan bahwa Jika medium dan lingkungan pertumbuhan sama seperti medium dan lingkungan sebelumnya, mungkin tidak diperlukan waktu adaptasi.…”

“…was a decrease in the absorbance value of the positive control and an increase in the control extract after incubation. The increase in absorbance in the control extract was made possible by extracting particles that were not completely dissolved, apart from an error in the measurement on the photometer; dirty cuvette walls, air bubbles, and insoluble particles 14 .…”

Trichophyton rubrum is the most common causative agent of anthropophilic dermatophytosis worldwide. Treatment of dermatophytosis can use natural ingredients. In Indonesia, several medicinal plants have been used, one of which is red galangal (Alpinia purpurata (Vieill.) K. Sch). This study aims to determine the effectiveness of red galangal rhizome chloroform extract on the growth of Trichophyton rubrum. This study is a True Experiment study with Posttest Only With Control Group Design consisting of 8 treatments namely positive control, extract control, 0 mg/mL (negative control), 20 mg/mL, 30 mg/mL, 40 mg/mL, 50 mg/ml, and 60 mg/mL extract of red galangal rhizome chloroform with 3 repetitions. The antifungal activity test was carried out using the determination of Minimum Inhibitory Concentration (MIC), Minimum Fungicidal Concentration (MFC), and Bioautography Test. The results showed that the red galangal rhizome chloroform extract in the Agar Overlay Bioautography Test contained an inhibition zone on the growth of Trichophyton rubrum. The determination of MIC and MFC were 20 mg/mL and 40 mg/mL, respectively. The study concludes that the red galangal rhizome chloroform extract affects the growth of the fungus Trichophyton rubrum. Research can be continued by knowing more specifics about the bioactive compounds from the red galangal rhizome, which have antifungal activity against Trichophyton rubrum.
