Abstract

One of the plants that can be used as a natural dye is senggani fruit. This study aimed to determine the effect of acid pH on the anthocyanin levels of the senggani fruit extract. The method used in this study uses UV-Vis Spectrophotometry. The sample was senggani fruit extract, added with an acidic pH solution (1-6) with 3 repetitions for 18 samples. Based on the results of research that has been carried out, the average anthocyanin levels at pH 1 are 2.00% with a bright red color; pH 2 is 1.63% with a red-orange color, pH 3 is 1.45% with an orange color, pH 4 is 2.05 % with brownish red color, pH 5 is 1.38% with brownish orange color, and pH 6 is 1.11% with light brown color. Based on statistical tests using Simple Linear Regression, Ha was accepted so that it could be concluded that there was an effect of acid pH on the anthocyanin levels of the senggani fruit. Based on a study that has been done, it is known that the sourer the pH solution is, the taller the anthocyanin obtained. Matter happens Because absorbance is comparable with the rate of anthocyanin something sample.

Abstract

This research investigates the effect of forest guava fruit yogurt (Bellucia pentamera Naudin) on the growth of Escherichia coli bacteria in mice (Mus musculus). The study utilized an experimental design with treatment and control groups. Mice were divided into four groups: three treatment groups received forest guava fruit yogurt at concentrations of 5, 10, and 15%, respectively, administered at 0.5 ml per dose daily for 14 days, while the control group was given plain yogurt. E. coli growth was assessed by analyzing fecal samples from each group. The findings revealed that the growth of E. coli bacteria in the mice decreased significantly after administration of forest guava fruit yogurt, with the most pronounced reduction observed in the group receiving the 15% concentration. In contrast, the control group, which received plain yogurt, exhibited a less marked decrease in E. coli growth. These results suggest that forest guava fruit yogurt has a stronger inhibitory effect on E. coli bacteria compared to plain yogurt. In conclusion, forest guava fruit yogurt appears to be an effective natural agent for reducing E. coli growth in mice, potentially offering added health benefits beyond those of conventional yogurt.

Abstract

HIV/AIDS cases in Indonesia remain high, particularly among adolescents. Limited knowledge and the perception that HIV/AIDS is a taboo topic make adolescents vulnerable to risky behaviors. This community service activity aimed to improve adolescents’ knowledge about HIV/AIDS and to introduce the Pantau HIV/AIDS (PAHIVA) application as an Android-based early detection tool. The implementation methods included preparation (coordination, permission, and material development), implementation (health education and PAHIVA application introduction), and evaluation (pre-test and post-test). The activity was carried out at SMA Negeri 6 Singkawang Utara, involving 40 participants consisting of students, guidance counselors, and the school principal. The Wilcoxon test showed a significant increase in students’ knowledge, with a median pre-test score of 72 (53–87) and a post-test score of 86 (67–100), p = 0.002. The program’s outputs included mass media publication, video documentation, and educational pamphlets. These results indicate that digital application-based health education is effective in improving adolescents’ literacy about HIV/AIDS. This activity is expected to serve as a promotive-preventive education model that can be sustained through peer group strengthening and collaboration between schools and health facilities.
