Abstract

This study examines the transformational leadership strategies of school principals in enhancing teachers’ professional competence, the obstacles encountered, and the supporting factors involved. Using a qualitative descriptive approach, the research was conducted at SDN Tiro, SDN Lhok Igeuh, and SDN Daya Blang Keudah through interviews, observations, and documentation. The findings show that principals apply transformational leadership by promoting professional development, encouraging enthusiasm for learning, and recognizing teacher efforts. Key obstacles include differences in teachers’ intellectual capacity, socioeconomic status, education levels, seniority, and frequent policy changes. Supporting factors include government support, collaboration among principals, a positive work environment, internal motivation, effective supervision, and the presence of competent teachers.

Abstract

Malaria, caused by the Plasmodium parasite, represents a significant global health challenge, with approximately 229 million cases reported in 2020. Current treatments include artemisinin-based combination therapy; however, drug resistance poses serious issues. Natural products, including alkaloids from Sida rhombifolia, particularly cryptolepine, effectively inhibit Plasmodium falciparum through DNA intercalation. Research indicates that mutations in the PfDHFR enzyme of P. falciparum contribute to drug resistance, highlighting the urgent need for new inhibitors. A literature review combined with SwissADME, toxicology predictions, and molecular docking methods identified 11-cryptolepine carboxylic acid (B1) and N-trans-feruloyl tyramine (B11) as potential new inhibitors. The compounds exhibited binding energies of −7.22 and −8.41 kcal/mol, which are close to the native ligand (−7.31 kcal/mol). Additionally, they demonstrate favorable drug-likeness properties, indicating their potential as viable candidates for drug development. The molecular dynamics simulation for 100 ns was conducted to observe molecular interactions in a specific system dynamically. It was found that ligand B1 has better stability compared to ligand B11. This compound demonstrates significant potential for advancing malaria treatment strategies. Further research and clinical evaluation are warranted to fully realize their potential and translate these findings into effective clinical interventions for combating malaria globally.

Abstract

Tagetes erecta is one of traditional herbs with a variety of pharmacological actions. This study attempted to assess the toxicity and antidiabetic activity of T. erecta leaf extract. The extraction was carried out by maceration, then continued with phytochemical analysis. Toxicity of the extract was conducted using the brine shrimp lethality test. The antidiabetic activity was evaluated by α-amylase inhibitory using the 3,5-dinitrosalicylic acid method. The phytochemical of the most active extract was identified using GC-MS and subjected to bind the α-amylase (PDB ID: 2QV4) employing molecular docking. The LC50 values of n-hexane, EtOAc, and MeOH extracts were 33.41, 14.00, and 35.03 ppm, respectively, indicating high toxicity. The antidiabetic activity showed that EtOAc extract has the lowest IC50 value (1053.95 mg/L). Molecular docking analysis revealed the compounds 1–5 has range of binding energy at −4.07 to −4.83 kcal/mol. Acarbose as a positive control showed the lower binding energy at −5.03 kcal/mol, indicated more effective α-amylase inhibitory. This study revealed that T. erecta leaf extract has significant cytotoxic potential, which may warrant further exploration for anticancer applications. However, the relatively weak α-amylase inhibitory and lower binding affinity compared to acarbose imply limited utility as an antidiabetic agent.

Abstract

This study aims to analyze the principal’s transformational leadership in improving teacher performance in schools. The research method employed is a qualitative approach, with data collection conducted through participant observation, in-depth interviews with the principal, vice principal for public relations, and teachers, as well as document analysis related to the principal’s transformational leadership. The study's results indicate that the principal employs transformational leadership, which fosters a positive work environment, encourages collaboration, and enhances teacher motivation. The individual attention given by the principal to teacher development is significant in improving their performance and creating a dynamic organizational culture. This culture motivates teachers to collaborate and improve the quality of teaching. Transformational leadership has a positive impact on teacher professionalism and performance, which ultimately improves educational outcomes. This study suggests that the application of the principal’s transformational leadership can enhance teacher performance and foster a positive organizational culture. These findings provide a reference for principals and related parties to strengthen leadership practices that support teacher professional development, thereby contributing to the improvement of education quality.

Abstract

Background. The purpose of this research was to examine the effect of compost enriched by Azolla microphylla and determine the optimal fertilizer dosage for the number of stems and leaves of king grass (Pennisetum Purpureophoides) in the third defoliation growth. Materials and methods. The research materials used the third defoliation king grass, compost from cow dung, and Azolla microphylla. The research method was experimental with completely randomized design (CRD) factorial patterns used in the study with the first factor, namely the dose of compost (K) with 3 doses, namely 10, 20, 30 ton / ha / defoliation and the second factor, namely the enrichment of Azolla microphylla (A ) with 3 doses, namely 10, 20, 30% of the dose of compost. There were 9 combination treatments which were repeated 3 times. King grass was planted on treatment plots with a spacing of 80 cm x 40 cm, and a distance between treatment plots of one meter. The research parameters measured were the number of stems and leaves of king grass. Data were analyzed using analysis of variance and followed by orthogonal polynomial test. Results. The results of the analysis of variance showed that the dose of compost had a significant effect (P <0.05) on the number of stems and leaves of king grass. Azolla microphylla dosing had a very significant effect (P <0.01) on the number of stems and leaves of king grass. The results of the analysis show that there is a single effect of each factor and there is no interaction. Conclusion. The results showed that the best treatment combination dose was K3A3, namely compost 30 ton / ha / defoliation, and 30% enrichment of Azolla microphylla.
