Abstract

ABSTRACTMonascus sp. MM was a contaminant fungus isolated from museum specimenpreserved with ethanol 70 %. In order to verify role of superoxide dismutase (SOD) inprotecting cell from ethanol toxicity during ethanol metabolism, SOD activities of Monascussp.MM and a Monmcus sp. NGK, which was isolated fiom fermented red rice (angkak), werecompared. When fungus was grown with glucose, CuIZn-SOD activity of Monascus sp., MMwas 7.1 times of thht of Monascus sp. NGK. Whereas in ethanol medium, CuIZn-SOD activityof Monarcus sp. MM was 24.6 times of that in Monascus sp. NGK. Induction of CuIZn-SODMonmcus sp. MM by ethanol was not observed. Compared with Mn-SOD, activity of CuIZn-SOD was markedly important (I 0 times of Mn-SOD when fungi grown with ethanol; 12 timeswhen the fungi grown with glucose). The data indicated that Cu/Zn-SOD might play animportant role in protecting cell fiom ethanol toxicity during ethanol metabolism. Ethanolrespiration rate of Monascus sp. MM was also important since O2 consumption and ethanoldegradation rates were clearly higher than that of Monascus sp. NGK.Keywords: Monarcw sp., superoxide dismutase, respiration, ethanol resistance.

Abstract

This study examines the role of Continuing Professional Development (CPD) as a strategy for developing teacher competency in the context of the Independent Curriculum. The study was conducted using a desk study method, reviewing scientific literature, research reports, and relevant education policy documents, particularly those published between 2015 and 2024. The analysis shows that Continuing Professional Development (CPD) serves as a strategic instrument for continuously improving teachers' pedagogical, professional, social, and personal competencies. Continuing Professional Development (CPD) not only helps teachers adapt to curriculum changes, such as differentiated and project-based learning, but also enhances professionalism, motivation, and learning innovation. However, the implementation of Continuing Professional Development (CPD) in Indonesia faces challenges, including time constraints, inconsistent material quality, varying teacher motivation, and disparities in access across regions. Therefore, optimizing Continuing Professional Development (CPD) requires targeted strategies, such as tailoring programs to teachers' real needs, utilizing digital technology, strengthening collaboration through Professional Learning Communities (PLC), and ongoing monitoring and evaluation.
