Abstract

The impact of neglecting vitamin intake, particularly vitamin C, extends beyond diminished immune function to include a reduction in metabolic processes, which can subsequently impair learning concentration and lead to declines in academic performance and nutritional status among students. Vitamin C is an essential micronutrient crucial for human health, serving as a potent antioxidant and bolstering the immune system. This study aims to provide education on various sources of vitamin C and its health benefits, as well as demonstrate vitamin C identification among students at MAN 3 Pontianak. This research is a descriptive design with a one-group pretest-posttest framework, involving 30 respondents. The findings reveal that out of 30 students (100%), the majority were aged 16 years, comprising 22 individuals (73.3%). The predominant gender among respondents was female, with 20 individuals (66.7%), while male respondents numbered 10 (33.3%). Prior to the educational intervention, student knowledge was categorized as good for 17 individuals (56.7%), adequate for 12 individuals (40%), and poor for 1 individual (3.3%). Following the educational intervention, all 30 students (100%) were classified as having good knowledge. This indicates a significant enhancement in the overall knowledge of vitamin C sources and their health benefits among students at MAN 3 Pontianak after the educational program.

Abstract

The use of formalin as a food additive is prohibited according to Indonesian Minister of Health Regulation No. 033 of 2012 concerning Food Additives (BTP). Due to its easy availability and its ability to extend shelf life, formalin is often misused as a food preservative. Given its carcinogenic properties, the use of formalin in food poses health risks. The purpose of this community service is to provide education on the dangers of formalin, identification techniques for formalin, and de-formalization efforts in food products. The community service was conducted on July 25, 2024, with 30 students from MAN 3 Pontianak participating. The service was carried out using an outreach method at MAN 3 Pontianak, including pre-tests, material delivery, demonstrations, and post-tests. The results from the pre-test and post-test show an average knowledge increase of 19% regarding formalin risks and reduction efforts. Following the education through material presentation and demonstrations, the number of students with good knowledge increased to 26 (86.7%), while those with insufficient knowledge decreased to 4 (13.3%). The attitude assessment revealed that all students at MAN 3 Pontianak had a positive attitude towards the dangers of formalin and efforts to reduce formalin risks in food (100%).

Abstract

Commercial antiperspirant products commonly incorporate synthetic compounds, several of which have raised concerns due to their potential carcinogenicity. Moreover, the inclusion of natural antibacterial agents in these formulations remains limited. Hibiscus sabdariffa L. (Rosella), a plant rich in bioactive secondary metabolites, offers a promising natural alternative. This study aimed to evaluate the antibacterial efficacy of rosella-based antiperspirant formulations, particularly against Staphylococcus epidermidis, a key contributor to body odor. Three formulations (F1, F2, and F3) were developed and assessed based on several parameters: pH, organoleptic properties, homogeneity, spreadability, adhesiveness, and antibacterial activity against Staphylococcus epidermidis. The results demonstrated that the antiperspirant preparations complied with standard evaluation criteria. Furthermore, the antibacterial assay outcomes yielded statistically significant differences (p < 0.05) in the mean diameter of the inhibition zones, indicating that H. sabdariffa L. exhibited measurable antibacterial activity against S. epidermidis. These findings support the potential application of Rosella extract in developing natural and efficacious anti-perspirant products.

Abstract

Body malodor results from the bacterial breakdown of apocrine gland secretions, with Staphylococcus epidermidis identified as a key contributor. Conventional deodorants often rely on synthetic compounds that may cause skin irritation or pose long-term health risks. This study aimed to formulate and assess an antibacterial roll-on deodorant containing methanolic extract of Spatholobus littoralis Hassk., a Kalimantan-native medicinal plant known for its antibacterial properties. The extract, prepared via maceration, was incorporated into a multiphase emulsion base comprising zinc ricinoleate, aluminum potassium sulfate, Carbopol 940, triethanolamine, Lexemul CS20, BHT, and phenoxyethanol. The formulations were evaluated for their physicochemical characteristics—pH, spreadability, adhesiveness, and homogeneity—as well as antibacterial activity against S. epidermidis using the disc diffusion assay. The extract-containing formulations (F1–F3) exhibited a beige color, herbal aroma, and uniform texture. The pH values (4.12–4.35) were within the dermally acceptable range. The spreadability varied from 4.59 to 4.81?cm, while the adhesiveness ranged from 0.34?s to 5.25?min, indicating favorable application and retention properties. Antibacterial testing showed inhibition zones of 10.40–12.37?mm, comparable to a commercial control (p?>?0.05). These findings suggest that S. littoralis extract is a potential natural, skin-compatible antibacterial agent for topical deodorant applications
