Introduction: The ethanol extract from citronella grass (Cymbopogon nardus) has been found to contain saponins, phenolics (flavonoids), and polyphenols which have antibacterial activity. As a result, researchers developed an antiseptic gel that contains this ethanol extract. Aims: This study aims to find the optimum concentration of gelling agent required to make the gel and to use physical evaluations in order to understand whether combining gelling agents may increase the quality of the gel. Methods: The gel was made using a melting method, which mixed the base of gel with citronella ethanol extract at a temperature of 40oC to form a homogeneous phase. The gel evaluation was conducted using an organoleptic test, homogeneity test, dispersion test, pH test, and adhesion test. Results: The tests were carried out on 15 formulations respectively (R1, R2, and R3), and resulted in the production of clear, translucent yellow gel with a distinctive citronella grass odor. The homogeneity test showed that all formulations were homogeneous and contained no agglomerated particles. The gel dosage forms made with CMC-Na, gum arabic, and gelatin as gelling agents resulted in having a pH of 7 whilst gels made with a combination of gelling agents resulted in having a pH of 8. The combination of gum arabic and CMC-Na gelling agents showed an increase in spreadability of gel formulas at the same concentration of composition, of which the combinations were 1.25% gum arabic and 1.25% CMC-Na. The gel adhesion time was 0.2-2 minutes for all formula. Conclusion: Based on this test data, it can be concluded that the 15 gel formulations that resulted from this research are good and further testing can be performed to determine the most optimum and stable formula.

The purpose of this study was to develop triangulation coding methods for a large-scale action research and evaluation project and to examine how practitioners and policy makers interpreted both convergent and divergent data. We created a color-coded system that evaluated the extent of triangulation across methodologies (qualitative and quantitative), data collection methods (observations, interviews, and archival records), and stakeholder groups (five distinct disciplines/organizations). Triangulation was assessed for both specific data points (e.g., a piece of historical/contextual information or qualitative theme) and substantive findings that emanated from further analysis of those data points (e.g., a statistical model or a mechanistic qualitative assertion that links themes). We present five case study examples that explore the complexities of interpreting triangulation data and determining whether data are deemed credible and actionable if not convergent.

In view of the dire state of literacy levels in South Africa and the fact that few literacy programmes provide research reports to evaluate best practices and effectivity, this article reports on the evaluation of a literacy project. The project, inspired by two children, is referred to as the Zoë-reading aloud project and targeted children in and around Upington in the Northern Cape, South Africa. The project was set up according to acknowledged reading promotion principles and it was structured to collect detailed data. Qualitative and quantitative data collection methods were used and a selection of methods provided reliability. The findings of the analysis of a collection of data for a period of 15 months revealed the best practices of the project. It highlights, for example, the need for financial assistance and challenges the concept of family literacy in low-literate and poor communities.
