Based on quantitative research techniques, the writer was given the correlation between independent factors and population-dependent variables in this study. Pre-experimental design. The research was conducted at SMA PGRI 117 Tangerang. The pre-test and post-test scores revealed significant (2-tailed) findings of 0.077 a (0.05), where the significance score was higher than 0.05, based on the calculation table data normality. It indicates that the pre-test and post-test data are both normal. As a result, the data used in this study are normal, allowing for a smooth transition to the subsequent statistical test. Based on the statistical calculation, there is a positive influence between teaching listening skills by VOA Learning English website and without VOA Learning English website. The result shows that the value of the tscore (15.412) is higher than the ttable (1.714) at the significance degree of 5%.

In Sumatera, gambir was used as a traditional treatment for fever, diarrhoea, diabetics and wound healing. AIM: To explore the efficacy of gambir extract on TNF alpha level, prostaglandin E2 level, lesson area, body weight, lipid profile and leptin level in Wistar rat-model gastritis. METHODS: This study was an experimental study, with a pre-post-test control group design. The subjects in this study were 30 male rats, 8 weeks old, weight 150-200 gram. Rats were administered with gambir extract at the dose of 20, 40 and 80 mg/kg BW/day for 3 days. Gambir was extracted by maceration methods. Statistical analysis was performed by SPSS 18. RESULTS: Gambir extract at the dose of 80 mg/kg BW exhibited the highest efficacy in reducing TNF alpha level, lesion area and increasing prostaglandin E2 level compared to gambir extract at doses of 20 mg/kg BW, 400 mg/kg BW, negative control, and positive control. CONCLUSION: Gambir extract was effective in reducing TNF alpha level, lesson area, and increasing prostaglandin E2 level in Wistar rat-model gastritis
