Abstract

The Sungkai plant (P. canescens Jack) is known to have medicinal properties in the traditional treatment of skin diseases. The aim of this research is to identify groups of phytochemical compounds contained in the methanol extract from Sungkai leaves, as well as evaluate the ability of the methanol extract to inhibit the growth of P. acnes bacteria. In the first stage, phytochemical screening was carried out from the methanol extract of Sungkai leaves. The results of this screening show that the methanol extract of Sungkai leaves contains alkaloids, flavonoids, phenols, triterpenoids and tannins. In the antibacterial activity test, the diffusion method with the well technique was used at extract concentrations of 1%, 5%, 10%, 15% and 20%. As a comparison, the positive control used clindamycin with a concentration of 2 µg/disk, while the negative control used Na-CMC with a concentration of 0.5%. The results of the antibacterial activity test showed that at a concentration of 1%, the methanol extract of Sungkai leaves had an inhibition zone with moderate intensity. However, at a concentration of 20% as well as in the positive control clindamycin with a concentration of 2 µg/disc, there was a stronger zone of inhibition. Thus, these findings indicate that methanol extract from Sungkai leaves has the potential to inhibit the growth of P. acnes, which is often associated with skin problems. The phytochemical compounds contained in this extract can be the basis for potential development in natural-based skin

Abstract

The transition into a higher education environment often triggers academic pressure demanding optimal adaptive performance and a balance between study and personal life. Amidst modernization challenges, the local wisdom value of Bapukung holds strategic potential as an often-overlooked internal resource for self-management. This study aims to construct a predictive structural model to explain the mediating mechanism of dynamic strategic capabilities in the relationship between cultural affiliation and student performance outcomes. Data were collected via a survey of 81 first-year female students in South Kalimantan and analyzed using the Regularized Structural Equation Modeling method with the Least Absolute Shrinkage and Selection Operator penalty. This statistical approach was applied to perform simultaneous variable selection to generate precise parameter estimates within a limited sample size. Analysis results indicate that cultural affiliation significantly builds the capabilities of sensing, seizing, and reconfiguring resources. A crucial finding from the model selection is a unique role specialization: the reconfiguring capability dominantly determines adaptive performance, while the seizing capability exclusively determines study-life balance. This study concludes that local culture serves as a vital foundation for developing modern self-management competencies, in which mental flexibility is the key to academic achievement and decisiveness is the determinant of life well-being.
