Abstract

Differences in student learning styles demand adaptive and personalized learning strategies. This study aims to develop a web-based learning strategy recommendation system utilizing Artificial Neural Network (ANN) to model the relationship between students' learning styles and appropriate learning strategies. Learning style identification was conducted using the Felder-Silverman questionnaire encompassing four dimensions: active–reflective, sensing–intuitive, visual–verbal, and sequential–global. The study employed a Research and Development (R&D) method with the 4D model and Personal Extreme Programming (PXP) approach. Data were collected from 25 seventh-grade students at SMP Negeri 1 Tomilito. A Multilayer Perceptron ANN model was trained using the backpropagation algorithm over 3,000 epochs, yielding a Mean Squared Error (MSE) value of 0.0541, indicating a relatively low prediction error rate. System feasibility testing obtained a score of 85.42%, categorized as "Very Feasible." The developed system is capable of identifying students' learning styles and automatically generating learning strategy recommendations, thereby potentially supporting teachers in designing more adaptive and personalized learning experiences. Perbedaan gaya belajar siswa menuntut adanya strategi pembelajaran yang adaptif dan terpersonalisasi. Penelitian ini bertujuan mengembangkan sistem rekomendasi strategi pembelajaran berbasis web yang memanfaatkan Artificial Neural Network (ANN) untuk memodelkan hubungan antara gaya belajar dan strategi pembelajaran yang sesuai. Identifikasi gaya belajar dilakukan menggunakan kuesioner Felder-Silverman yang mencakup empat dimensi: aktif–reflektif, sensori–intuitif, visual–verbal, dan sequential–global. Penelitian menggunakan metode Research and Development (R&D) dengan model 4D dan pendekatan Personal Extreme Programming (PXP). Data dikumpulkan dari 25 siswa kelas VII SMP Negeri 1 Tomilito. Model ANN Multilayer Perceptron dilatih menggunakan algoritma backpropagation dengan 3000 epoch dan menghasilkan nilai Mean Squared Error (MSE) sebesar 0,0541, yang mengindikasikan tingkat kesalahan prediksi yang relatif rendah. Hasil uji kelayakan sistem memperoleh skor 85,42% dengan kategori "Sangat Layak". Sistem yang dikembangkan mampu mengidentifikasi gaya belajar siswa dan memberikan rekomendasi strategi pembelajaran secara otomatis, sehingga berpotensi mendukung guru dalam merancang pembelajaran yang lebih adaptif dan personal.

Abstract

Knowledge management (KM) has been widely recognized as a strategic enabler for organizational performance and information systems development, yet its systematic adoption in higher education institutions (HEIs) remains limited, particularly in Indonesia. This study presents an institutional KM readiness assessment at two universities in Gorontalo Province, Universitas Negeri Gorontalo (UNG, public) and Universitas Ichsan Gorontalo (UNISAN, private), as an initial descriptive baseline in this regional context. A quantitative descriptive survey was conducted using an instrument grounded in the Knowledge Management Critical Success Factors (KMCSF) framework, covering three aspects: Abstract (conceptual awareness), Soft (human and organizational factors), and Hard (technology and infrastructure). Data were collected from 226 respondents through purposive sampling. The study aims to assess KM readiness levels at both institutions and compare readiness profiles across the three aspects to identify strengths and priority areas for IS-informed governance improvement. Validity and reliability of the instrument were confirmed on this study's data prior to main data collection. Readiness levels were interpreted using a five-level readiness scale, where classifications reflect overall average scores across all dimensions. Results indicated that UNISAN obtained a score corresponding to Level 4 (Receptive) while UNG obtained Level 5 (Optimal), with both institutions showing relative strengths in technology infrastructure and organizational structure. However, knowledge hub and centers, explicit knowledge management, and organizational culture emerged as shared areas requiring priority attention. These findings establish a descriptive KM readiness baseline for HEIs in Gorontalo Province and offer evidence-based directions for knowledge management system design and IS governance improvement.

Abstract

The study of animal and plant cell materials is often challenging for students due to their microscopic and abstract nature, making them difficult to visualize through conventional media. This condition negatively impacts students' conceptual understanding and learning outcomes. This study aims to develop an Augmented Reality (AR)-based learning medium on the Android platform capable of projecting animal and plant cell structures interactively in three-dimensional format. A Research and Development (R&D) approach was employed following the ADDIE model. The trial subjects consisted of 10 eighth-grade junior high school students, one media expert, and one content expert. Data collection instruments included validation sheets, student response questionnaires, and learning achievement tests (pre-test and post-test). Media expert validation reached 96.25% and content expert validation reached 82.67%, while student responses showed 90%, all categorized as very feasible. Based on the effectiveness test, an average N-Gain score of 0.78 was obtained, classified as high. These results indicate that the developed AR-based learning medium can significantly improve students' conceptual understanding and has the potential to serve as an innovative and adaptive alternative learning medium. Materi sel hewan dan sel tumbuhan seringkali menjadi tantangan bagi siswa karena karakternya yang mikroskopis dan abstrak, sehingga sulit divisualisasikan melalui media konvensional. Kondisi ini berdampak pada rendahnya pemahaman konsep dan hasil belajar siswa. Penelitian ini bertujuan mengembangkan media pembelajaran berbasis Augmented Reality (AR) pada platform Android yang mampu memproyeksikan struktur sel hewan dan sel tumbuhan secara interaktif dalam format tiga dimensi. Pendekatan yang digunakan adalah Research and Development (R&D) dengan mengacu pada model ADDIE. Subjek uji coba terdiri dari 10 siswa kelas VIII SMP, satu ahli media, dan satu ahli materi. Instrumen pengumpulan data mencakup lembar validasi, kuesioner respons siswa, serta tes hasil belajar (pre-test dan post-test). Hasil validasi ahli media mencapai 96,25% dan ahli materi sebesar 82,67%, sedangkan respons siswa menunjukkan angka 90%, ketiganya berada pada kategori sangat layak. Berdasarkan uji efektivitas, diperoleh skor rata-rata N-Gain sebesar 0,78 yang termasuk dalam klasifikasi tinggi. Hasil ini menunjukkan bahwa media pembelajaran berbasis AR yang dikembangkan mampu meningkatkan pemahaman konsep siswa secara signifikan dan berpotensi menjadi alternatif media pembelajaran yang inovatif dan adaptif.

Abstract

The rapid advancement of digital technology in Indonesia presents both opportunities and challenges for rural economic actors, particularly village-owned enterprises (BUMDesa). While urban MSMEs have increasingly adopted digital platforms, many BUMDesa continue to face structural and managerial barriers to digital integration. This study addresses these issues by developing the platform, a web-based application designed to enhance BUMDesa management capacity through knowledge sharing and stakeholder collaboration. Guided by the Knowledge-Based Economy and Pentahelix collaboration model, the system integrates a digital knowledge repository, user role management, web services using XML/JSON, and modules for training, article exchange, and community QA. The prototype was developed using the Waterfall method and deployed in Gorontalo and North Sulawesi. Results indicate that SIBUDE effectively facilitates real-time communication, automatic knowledge dissemination, and multi-sector cooperation. It enables BUMDesa to learn from each other, share innovations, and access a centralized, structured repository that supports continuous improvement. The study concludes that knowledge-driven digital systems can significantly empower rural enterprises by promoting transparency, innovation, and operational efficiency. Recommendations include strengthening institutional adoption, expanding data automation features, and aligning local governance with digital transformation strategies.
