Abstract

Exposure to ultraviolet (UV) radiation from sunlight can induce erythema, sunburn, and skin sensitivity, culminating in dermal damage. The application of sunscreen mitigates potential skin harm resulting from solar radiation. This investigation aims to ascertain the optimal formulation for lotion preparations incorporating Orthosiphon aristatus leaf extract and evaluate the sunscreen efficacy of said formulations through in vitro testing. Extraction procedures involved ethanol maceration, followed by phytochemical characterization of the resultant extract. Formulation of the extract into oil-in-water (O/W) lotion preparations was executed, with optimization conducted utilizing the Simplex Lattice Design (SLD) method, incorporating varied concentrations of stearic acid, cetyl alcohol, and olive oil to assess their impact on lotion viscosity, spreadability, and adhesion. Subsequent evaluation encompassed in vitro assessment of sunscreen activity for both the lotion and extract. Findings revealed the presence of flavonoids, saponins, and tannins in the extract. Optimal lotion formulation, determined via the SLD method, yielded concentrations of 2.00, 4.22, and 8.78 for stearic acid, cetyl alcohol, and olive oil, respectively. Formulation optimization was guided by minimizing viscosity while maximizing spreadability and adhesion. Confirmation studies underscored the predictive capacity of the SLD method in determining viscosity, spreadability, and adhesion of the cat's whiskers leaf extract lotion. SPF values for the extract and lotion were recorded as 33.63 ± 0.963 and 2.54 ± 0.001, respectively, at a concentration of 30,000 ppm.

Abstract

This study looks at the contribution of Rohani Islam (Rohis) in the formation of religious character education through its various activity programs. Seeing the widespread phenomenon such as juvenile delinquency, character education is the solution to these problems. The purpose of this study is to describe Rohis' contribution in the formation of religious character education and supporting and inhibiting factors in the formation of religious character education at SMA Negeri 1 Parakan. This research approach uses a narrative approach. This type of research uses field research with qualitative research methods. Primary data sources were obtained from interviews with Rohis members, chairmen and coaches, educators, principals and waka students of SMA Negeri 1 Parakan and secondary data sources from books related to Rohis extracurricular activities and documentation of Rohis activities. Data collection techniques by observation, interviews, and documentation studies. This research data analysis technique with data reduction steps, data presentation, followed by drawing conclusions. Triangulation of this research data using triangulation techniques and sources. This research approach uses a narrative approach. This type of research uses field research with qualitative research methods. Primary data sources were obtained from interviews with Rohis members, chairmen and coaches, educators, principals and waka students of SMA Negeri 1 Parakan and secondary data sources from books related to Rohis extracurricular activities and documentation of Rohis activities. Data collection techniques by observation, interviews, and documentation studies. This research data analysis technique with data reduction steps, data presentation, followed by drawing conclusions. Triangulation of this research data using triangulation techniques and sources. The results showed that Rohis' contribution in shaping character education was integrated through comprehension activities, through habituation, and through the example given by coaches and educators to students. The supporting factors of Rohis in the formation of religious character education are support from the school, the enthusiasm of students in participating in activities, and adequate infrastructure, while the inhibiting factor is limited activity time.
