Abstract

This study explores the effectiveness and challenges of implementing the Contextual Teaching and Learning (CTL) model in multicultural classrooms, particularly focusing on its impact on interpersonal skills development. The primary aim is to investigate how the CTL model enhances student engagement by connecting academic content to real-world contexts and to identify the barriers that impede its effective application. This research utilized a qualitative approach with a case study method to examine the application of the CTL (Contextual Teaching and Learning) model in building inclusive learning communities and fostering interpersonal skills in multicultural classrooms. The data collection techniques used in this study included interviews, observations, and document analysis. The findings indicate that while the CTL model significantly enhances student engagement and fosters the development of interpersonal skills, its implementation is fraught with challenges. Key obstacles include insufficient teacher training, misalignment with existing curriculum standards, limited resources, and institutional barriers such as rigid schedules and lack of administrative support. Despite these challenges, the research highlights the importance of sustained professional development and a supportive learning community to overcome these barriers. By addressing these issues, educators can better leverage the CTL model to create inclusive and effective learning environments. Overall, this study underscores the potential of the CTL model to transform teaching practices and improve student outcomes in multicultural settings. It calls for a concerted effort to provide the necessary support and resources for educators to implement the CTL model successfully, thereby enhancing educational experiences and fostering inclusive learning communities.

Abstract

This research aims to develop teaching materials based on local wisdom to improve the interpersonal skills of prospective elementary school teachers. The background of this research is based on the low interpersonal skills of prospective students of Elementary School Teachers at the Faculty of Teacher Training (FKIP) Cenderawasih University (Uncen) Papua. The strategy used to improve students' interpersonal skills is to integrate Khombouw into the teaching materials of the Basic Concepts of Science Elementary School. Khombouw is a local wisdom made of bark from red khombow trees (Ficus nodosa teijsm & Binn) and white khombow (Ficus variegata Blume), which grow in Sentani, Papua. This research is a research development (R&D) of the ADDIE (Analyze, Design, Development, Implementation) design model. The results of student self-assessment on the implementation of teaching materials based on Khombouw Local Wisdom Model Guided Inquiry on interpersonal skills were 69.5% in the "good" criterion, 28.2% in the "very good" criterion, and 5.1% in the "quite good" criterion. Lecturers' observations of interpersonal skills showed results that were not much different, namely 74.3% on the good criteria, 25.6% on the very good criteria, and 7.6% on the good criteria. The value of N < g> obtained was 0.27 and was included in the low criteria. A thorough evaluation and in-depth analysis of the factors that affect the low N-Gain value is required.

Abstract

Highlights Ganyong tuber exhibits immunomodulatory activity against Staphylococcus aureus infection in mice. Ganyong tuber extract increases phagocytic activity, leukocyte count, and spleen weight in infected mice.   ABSTRACT Background:  Ganyong tubers (Canna edulis K.) are widely consumed by Indonesians as an alternative food source. However, no studies have investigated the pharmacological properties of ganyong tubers, particularly their immunomodulatory activity. Objective: This study aimed to evaluate the immunomodulatory effects of ganyong tubers in mice infected with Staphylococcus aureus. Material and Method: This study used a randomized experimental design involving 30 male BALB/c mice divided into five groups, including a normal control, a negative control (infected with Staphylococcus aureus), and three groups treated with ganyong (Canna edulis K.) extract at doses of 50, 100, and 150 mg/kg BW. The extract was administered orally for seven days, followed by S. aureus injection. Phagocytic activity, leukocyte count, spleen weight, and antibody levels were evaluated using microscopy and ELISA. Data were analyzed using one-way ANOVA and Duncan’s post hoc test. Result: This study evaluated the immunomodulatory effects of ganyong tuber (Canna edulis K.) extract on phagocytosis activity and capacity, leukocyte count, spleen weight, and antibody levels in mice infected with Staphylococcus aureus. Phagocytosis activity and capacity were highest in the group receiving 50 mg/kg body weight (BW) extract, with decreasing effects at higher doses. Leukocyte counts were highest in the infected untreated group, while spleen weight was significantly increased in the 50 mg/kg BW treatment group compared to controls. Although the 100 mg/kg BW group showed the highest antibody levels, these differences were not statistically significant. Conclusion: Ganyong tuber extract demonstrated immunomodulatory activity by enhancing innate immune responses against S. aureus infection.

Abstract

Diabetic ulcers are frequently complicated by infections from multidrug-resistant bacteria such as Alcaligenes faecalis, necessitating the development of alternative therapeutic strategies. Bacteriophage therapy presents a promising approach due to its specificity and efficacy against antibiotic-resistant pathogens. This study aimed to formulate and evaluate a bacteriophage-based topical cleanser using the phage ϕAFaV1 for treating A. faecalis infections, focusing on high antibacterial efficacy and low dermal toxicity. Three suspension formulas (F1, F2, F3) were prepared with varying chitosan concentrations (0.5; 0.75, and 1.0%) as a suspending agent. These formulations underwent physical stability testing over 28 days, including assessments of viscosity, pH, zeta potential, and homogeneity. Antibacterial efficacy was determined through inhibition zone assays. All three formulations effectively inhibited bacterial growth, forming clear zones. The F2 formula (0.75% chitosan), containing 200 µL of active phage ingredient, was identified as the optimum formulation. It demonstrated superior physical stability and the most effective bactericidal activity against A. faecalis, as confirmed by statistical analysis. These results indicate that a bacteriophage suspension stabilized with 0.75% chitosan is a highly promising and stable topical agent for combating multidrug-resistant A. faecalis in diabetic wound care.
