Abstract

East Kalimantan is one of the areas that have the potential for various traditional medicinal plants. Melastoma malabathricum (known locally as karamunting, senduduk) is an invasive plant in the family of Melastomataceae with a potential medicinal plant. This study explored the potential of twigs and stem bark of Karamunting (Melastoma malabathricum) for its antioxidant and antibacterial activity. The twigs and stem bark of Karamunting were macerated to yield ethanolic extract. The phytochemical screening was evaluated by Harborne and Kokate methods. Antioxidant activity was evaluated by DPPH radical scavenging assay. Antibacterial activity was examined using agar well diffusion method against Propionibacterium acnes. The results showed that the ethanol extracts of twigs and stem bark samples display an ability to inhibit DPPH free radical by 82% and 88% at 50 ppm concentration. Antibacterial activity of the twigs and stem bark samples showed potent activity to inhibit the P. acnes growth with 11.3 mm and 11 mm inhibition activity. Based on the results, the twigs and stem bark of M. malabathricum plants display potential as a natural antioxidant and antibacterial agent.

Abstract

The Competency-Based Curriculum (KBK) approach is one of the solutions that is expected to be able to answer the needs of the times. However, reality shows that many high school graduates still face challenges in optimally integrating hard skills and soft skills. This study aims to analyze the influence of Competency-Based Curriculum management on the development of soft skills and hard skills competencies of high school graduates. This study uses a quantitative approach with a survey method to analyze the influence of Competency-Based Curriculum management on the development of soft skills and hard skills of high school graduates. This study shows that the management of the Competency-Based Curriculum (KBK) at the high school level has a significant positive influence on the development of students' soft and hard skills. From the aspect of curriculum management, planning obtained the highest score (85 out of a scale of 100), followed by implementation (80) and evaluation (78), which shows that the school has made optimal efforts in designing and implementing KBK, although the evaluation stage still needs improvement. In the development of soft skills, communication and cooperation skills received the highest scores of 85 and 84, respectively, while leadership and time management obtained scores of 75 and 72. On the other hand, students' mastery of hard skills is also in the good category with the highest score on technology-based skills (86) and the lowest score on analytical skills (74). The results of the linear regression test confirmed that there was a significant positive relationship between KBK management and the mastery of soft skills (regression coefficient 0.65; p < 0.01) and hard skills (regression coefficient 0.59; p < 0.01).
