Abstract

Facial wash gel is a gel-based facial cleanser widely used because it is easy to apply and provides comfort to the skin. This preparation requires a gelling agent to form a gel structure, so alternative natural ingredients from cassava tubers and peels (Manihot esculenta) were used. This study aimed to determine the ability of cassava tubers and peels as gelling agents in facial wash gel formulations and to evaluate the physical characteristics of the resulting preparation. The research method involved making flour and starch from cassava tubers and peels, then formulating them into facial wash gel preparations and conducting physical evaluation tests. The organoleptic test results showed that F1–F4 were in the form of thick sediment and F5 was in the form of a gel with a brown and white color and a distinctive soapy smell. The pH test results showed values ranging from 7.6–8.7 with significant differences between formulas. The foam height test results showed values of 2.0–2.4 and did not differ significantly between formulas. The homogeneity test results showed that only F5 was homogeneous, while F1–F4 were not homogeneous. The cleaning power test results showed that all formulations were able to reduce stains, with F3 having the highest cleaning power value. The conclusion of this study shows that cassava tubers and skin (Manihot esculenta) can be formulated as a facial wash gel, but it has not formed an optimal gel due to insufficient concentration, even though it has met the cleaning power capability.

Abstract

The irrational use of antibiotics is a significant factor in the development of antimicrobial resistance in the community. A low level of knowledge, particularly among adolescents, contributes to the practice of using antibiotics without a prescription and not in accordance with proper guidelines. The objective of this community service activity was to enhance the understanding of pupils at SMK Islam Nurul Iman Lampung Timur, Muara Gading Mas Village, regarding the appropriate use of antibiotics in order to prevent antimicrobial resistance. The method used was health education through interactive lectures, discussions, and the administration of questionnaires before and after the educational session. A total of 30 students participated in this activity. The findings revealed that there was an enhancement in the level of knowledge among students following the educational intervention since the average test result increased from 66.66% to 78.26%. The analysis proved that there was a significant difference between the level of knowledge before and after the educational intervention (p < 0.05).

Abstract

The 21st century is becoming a century of globalization. Still, the 2022 PISA survey states that Indonesian students have low science literacy, ranked 64 out of 81 countries. Hence, it is necessary to develop scientific knowledge and epistemic beliefs not to be left behind by the times. This study aims to analyze the characteristics and level of teacher understanding of epistemic beliefs and implications for learning science based on socio-scientific issues. The research used a qualitative study, and data were collected through interviews, observations, and tests. Eight science teachers responded to be analyzed using the constant comparison method by applying Nvivo media to support data analysis. The results showed relatively few teachers have an epistemic understanding of science learning. Hence, teachers generally believe that scientific inquiry must begin with questions and that the perceptions and biases of researchers strongly influence scientific conclusions. The novelty of this research lies in the research design and efforts that can be applied to improve the epistemic understanding of teachers, namely by presenting programs for pre-service and in-service teachers, providing regular workshops, and offering internships or research experiences to science teachers.
