Abstract

Utilizing endophytic fungi to discover metabolites by characterizing the fungi produced from robusta coffee beans can be highly beneficial without causing harm to the plants. Additionally, this approach aids in identifying raw materials for medical drug development, specifically compounds like chlorogenic acid, which hold promise as potential treatments for diabetes mellitus. This study aimed at characterizing the endophytic fungi present in Robusta coffee (Coffea canephora L.) beans through 18S rRNA gene sequencing and evaluation of antioxidant activity and chlorogenic acid content found in these endophytic fungi. Green, unripe Robusta coffee beans were harvested from a coffee plantation in Tana Toraja and isolated using Potato Dextrose Agar medium. The isolation process yielded three isolates, designated RF1, RF2, and RF3. Subsequently, the isolates were subjected to testing for endophytic fungi activity, and the isolate that exhibited activity was further characterized using 18S rRNA gene sequencing. Following that, the isolates were fermented using a Potato Dextrose Broth medium, resulting in two phases: filtrate and biomass. The filtrate was then extracted using ethyl acetate as the solvent. The extracted compound was subsequently evaluated for antioxidant activity using ABTS and DPPH methods, and the concentration of chlorogenic acid was measured. From the three isolates of endophytic fungi obtained from green Robusta coffee beans with the codes RF1, RF2, and RF3, all of them exhibited antibacterial activity against Escherichia coli and Staphylococcus aureus. The 18S rRNA gene sequencing analysis revealed that isolate RF1 was identified as Fusarium sp. For the evaluation of antioxidant activity using the ABTS method, an IC50 value of 53.49 µg/mL was obtained, while the DPPH method resulted in an IC50 value of 54.03. Furthermore, the measurement of chlorogenic acid content in the extract of endophytic fungi from Robusta coffee beans indicated a concentration of 11.58%. The characterization result of the endophytic fungi isolates from green Robusta coffee beans revealed the presence of Fusarium sp. It exhibited high antioxidant activity and a chlorogenic acid content of 11.58%.

Abstract

Representation plays a central role in mathematical problem solving, serving as a cognitive bridge between abstract concepts and concrete understanding. However, while prior studies have examined the effects of scaffolding in mathematics learning, limited attention has been given to the comparative impact of single versus multiple online representations, particularly in relation to students’ cognitive processes such as eye movement behavior. This study addresses this gap by investigating the effectiveness of online single and multiple representation scaffolding in enhancing students’ mathematical concept mastery, problem-solving performance, and eye movement patterns during problem-solving tasks. A quasi-experimental design was employed involving 300 high school students, randomly assigned to either a multiple representation scaffolding group (n = 150) or a single representation scaffolding group (n = 150). Data were analyzed using one-way MANCOVA, ANCOVA, MANOVA, and ANOVA tests. The results revealed that students who received multiple representation scaffolding outperformed their peers in mastering mathematical concepts, solving complex problems—including advanced-level tasks—and demonstrating more efficient visual processing, indicated by shorter fixation durations and rereading times. Furthermore, these students exhibited more adaptive strategies across varying question types (basic, combination, and advanced). The findings highlight the pedagogical advantage of using multiple representation scaffolding in online mathematics instruction, suggesting that it offers more comprehensive cognitive support and promotes deeper conceptual understanding. This study contributes to the growing body of research on digital scaffolding by evidencing the cognitive and performance-related benefits of multimodal representation and underscores its potential to inform the design of technology-enhanced mathematics learning environments.

Abstract

The Covid 19 pandemic has had such a big impact on the education system, especially the National education system. In the conditions of the Covid 19 pandemic, national learning is carried out online, both formal and non-formal education (training). Related to this, the authors conducted a study on the application of asynchronous and synchronous blended learning in Stunting Prevention and Handling Training held at the Ministry of Social education and training institutions. The purpose of this study is to find out the effectiveness and constraints of implementing asynchronous blended learning and synchronous training. The method used in this study is a literature study. The results of the study show that the implementation of asynchronous and synchronous blended online learning Training on Stunting Prevention and Handling is not yet effective. This is due to the asynchronous setting being carried out only with independent asynchronous (AM) without the presence of a facilitator. The existence of a facilitator can play an important role in maintaining and maintaining the level of student learning motivation and facilitating relationships between training participants and with the facilitator. Then in the implementation of synchronous online learning Training on Stunting Prevention and Handling is also considered less effective. The main obstacle is the internet network which is not accessible to participants, especially from remote areas. So that it is very difficult for participants to follow synchronous learning as a whole.

Abstract

Organizational restructuring serves as one of the key strategies to enhance the effectiveness of higher education governance, particularly in responding to the demands of digital transformation and national policies. This research aims to analyze change management in the restructuring of the Information and Communication Technology Development Agency (LPTIK) into the Technical Implementation Unit for Information and Communication Technology (UPA TIK) at Jambi University. The study focuses on the characteristics of the change, the change management strategies implemented, the challenges encountered, and the strategic opportunities arising from the restructuring. This research employs a qualitative approach using a case study method. Data collection was conducted through in-depth interviews with university leaders, UPA TIK leadership and staff, as well as information technology service users, complemented by document analysis. Data analysis was performed thematically, linking empirical findings to change management theories, including Lewin's model, Kotter's model, ADKAR, and McKinsey 7S. The findings indicate that the restructuring of LPTIK into UPA TIK constitutes a policy-driven and incremental organizational change, emphasizing structural adjustments and coordination pathways rather than comprehensive transformations in work processes and organizational culture. The implemented change management strategies were predominantly administrative and stability-oriented, successfully maintaining the continuity of information technology services in the short term. However, comprehensive implementation of change leadership, human resource management, persuasive communication, and change reinforcement systems remains lacking. This condition has led to symbolic resistance among staff and poses risks to the sustainability of the change in the long term. This study produces a conceptual model of change management, demonstrating that the success of organizational restructuring in higher education institutions is not solely determined by structural changes but is heavily dependent on the quality of change management strategies as a mediating variable. These findings contribute conceptually to the study of change management in higher education and provide practical implications for managing organizational restructuring in state universities.

Abstract

The Instrument Landing System (ILS) is a critical component of aviation navigation that ensures aircraft landing accuracy and safety. However, public understanding of restricted ILS areas and equipment placement criteria remains limited, as existing informational media—such as regulatory documents or slide presentations—lack interactivity and spatial visualization. This study aims to design and evaluate a Virtual Tour-based ILS Application as an interactive educational medium to visualize and explain the placement criteria of ILS equipment in a three-dimensional (3D) environment. The research used the ADDIE (Analysis, Design, Development, Implementation, Evaluation) instructional design model to systematically develop the application. The content and functional design were derived from the Indonesian Civil Aviation Authority’s SKEP/113/VI/2002 and ICAO Annex 10 Volume I standards. Data collection methods included observation, expert validation, and user testing. The application was evaluated using three quality dimensions of the ISO 25010 software standard: functional suitability, compatibility, and usability. Participants included media experts, subject matter experts, and 20 community members residing near Budiarto Airport, Indonesia. As a result, the Virtual ILS application achieved high evaluation scores across all dimensions—functional suitability (97.5%), compatibility (100%), and usability (90.16%)—indicating excellent performance, ease of use, and educational value. The interactive 3D visualization effectively improved users’ comprehension of ILS restricted zones and equipment placement requirements, compared to conventional informational media.
