Abstract

Penelitian ini bertujuan untuk mengevaluasi efektivitas ekstrak Aloe vera dalam menghambat pertumbuhan bakteri Pseudomonas aeruginosa, yang dikenal sebagai salah satu bakteri penyebab pembusukan ikan. Penelitian ini menggunakan pendekatan eksperimental dengan rancangan perlakuan berupa variasi konsentrasi ekstrak Aloe vera sebesar 0%, 25%, 50%, 75%, dan 100% sebagai variabel bebas, serta pertumbuhan Pseudomonas aeruginosa sebagai variabel terikat. Pengumpulan data dilakukan melalui metode observasi kuantitatif dengan mengukur diameter zona bening yang terbentuk di sekitar cakram kertas sebagai indikator daya hambat antimikroba. Analisis data dilakukan dengan uji Kruskall-Wallis pada taraf signifikansi 1% untuk mengetahui pengaruh signifikan antar perlakuan konsentrasi. Hasil penelitian menunjukkan bahwa ekstrak Aloe vera secara signifikan mampu menghambat pertumbuhan Pseudomonas aeruginosa dengan nilai signifikansi (P = 0,000), sehingga berpotensi digunakan sebagai agen antimikroba alami.

Abstract

This study aims to describe the optimization of Information and Communication Technology (ICT) utilization as a learning resource in the digital era at SMPN 4 Bataguh. The research focuses on teachers’ strategies in utilizing ICT to support the effectiveness and interactivity of the teaching and learning process. A descriptive qualitative approach was employed, with data collected through observations, interviews, and documentation. The findings indicate that ICT has been applied in various forms, including online learning applications, interactive learning media, and digital-based academic administration. Nevertheless, the utilization of ICT has not been optimally implemented. Several obstacles were identified, such as limited internet infrastructure, differences in teachers’ digital literacy levels, and the absence of continuous professional training related to ICT use in learning. These conditions affect the consistency and effectiveness of ICT integration in classroom practices. Therefore, strengthening teachers’ digital competencies and improving ICT facilities are essential to support effective and sustainable learning processes.

Abstract

This study aims to analyze how principal-led leadership strategies are operationalized to strengthen teacher competencies and structure the participation of educational staff within an integrated school quality management system at SMKN 2 Marabahan. Adopting a descriptive qualitative design, data were collected through in-depth interviews, observations, and document analysis involving the principal, teachers, and educational staff selected via purposive sampling. Data analysis followed the Miles and Huberman interactive model. The findings reveal that school quality improvement is enacted through three interrelated strategic mechanisms: continuous professional development via academic supervision and internal training, competency-based task delegation aligned with institutional needs, and the cultivation of a collaborative work culture. The principal functions as the coordinating actor who aligns these strategies, while teachers serve as the main instructional agents and educational staff operate as strategic partners in administrative management, digital services, and data governance. Participation is institutionalized through regular coordination meetings, shared decision-making forums, and the structured involvement of educational staff in planning and quality assurance processes. These mechanisms contribute to increased institutional efficiency, transparency, and collective accountability. The study concludes that inclusive and integrative leadership is critical for sustainable school quality management, as it connects teacher competence development with participatory governance involving educational staff. This model is particularly relevant for vocational schools navigating the challenges of digital transformation.

Abstract

This qualitative descriptive study examines the principal's supervisory role in improving digital-based educational quality at SMKN 2 Marabahan during the Industrial Revolution 4.0 era. Data were collected through semi-structured interviews with the principal, 15 teachers, and three staff members, supplemented by 20 classroom observations and documentation analysis. Analysis followed Miles and Huberman's interactive model with triangulation and member checking for validity. Findings reveal that the principal functions as an innovative supervisor through three strategies: implementing a Learning Management System for systematic monitoring, developing industry-aligned programs (industrial classes and Vocational Industrial Work Training), and facilitating continuous teacher professional development with a developmental rather than evaluative approach. Results showed the school's national accreditation score increased from 83.5 to 91.5 (9.6% improvement), digital competency test pass rates rose from 78% to 92%, and graduate employment rates increased from 65% to 81%. These findings demonstrate that technology-adaptive supervision significantly enhances vocational education quality, suggesting that principals must integrate digital technologies and industry partnerships for effective vocational education transformation in the digital era.
