Abstract

Lecturer performance is very important to support the progress of higher education. Determination of lecturer performance is based on Tri Dharma activities, including: teaching, research and community service. This study aims to build a model that can predict the predicate of lecturers from the activities carried out. The best model is obtained by comparing the use of two algorithms, namely Decision Tree and Naive Bayes. Data mining methods use the CRISP-DM method, namely business understanding, data understanding, data preparation, modeling, evaluation, and development. Performance testing of training data using K Fold Cross Validation. The modeling results with this performance show that the Decision Tree algorithm has better performance with 94.70%, accuracy, 93.24% precision and 96.33% recall, while Naïve Bayes algorithm has performance with 92.95%, accuracy 90.08% and 96.33%. This shows that modeling using the Decision Tree algorithm can be used as a model in determining lecturer performance.

Abstract

Effective financial management is essential for ensuring the optimal operation of educational institutions, including the Al Luqmaniyyah Islamic Boarding School in Yogyakarta. Traditional manual financial administration often leads to delayed reporting, inaccurate record-keeping, and limited accountability. To address these challenges, this study emphasizes the digitalization of payment processes through the development of a web-based digital payment information system that supports structured student billing management, including scheduled and monthly bills, as well as fully digitized payment transactions. The system was developed using the Software Development Life Cycle (SDLC) Waterfall model, employing Laravel version 11 and a MySQL database. It integrates multi-role authentication features using the Spatie Laravel Permission package to ensure secure and differentiated access. System validation was conducted through Black Box Testing with the Equivalence Partitioning technique, focusing on verifying functional correctness across core modules such as billing management, payment processing, and role-based access control. The testing process was carried out after system implementation in a production environment to ensure that application behavior aligned with predefined functional requirements. The results indicate that all system modules function in accordance with the specified design, achieving full functional validation. The digitalization of payment processes significantly simplifies financial transaction recording, minimizes administrative errors, and enhances transparency for both administrators and students. This study highlights the importance of payment digitalization in modernizing financial services in Islamic boarding schools and is expected to serve as a reference for similar system development initiatives in other pesantren environments.

Abstract

Permasalahan pengelolaan sampah masih menjadi tantangan di berbagai lembaga pendidikan, termasuk di lingkungan pondok pesantren. Di Pondok Pesantren Kun Sholihan, pengelolaan sampah belum menerapkan prinsip Reduce, Reuse, Recycle (3R) secara optimal, ditandai dengan kebiasaan santri membuang sampah tanpa pemilahan serta rendahnya kesadaran terhadap pengelolaan sampah berkelanjutan. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk memberdayakan santri melalui kampanye edukasi pengelolaan sampah berbasis video sebagai upaya meningkatkan pemahaman dan perubahan perilaku peduli lingkungan. Metode yang digunakan adalah pemberdayaan partisipatif (Participatory Action / Community Empowerment), yang dilaksanakan melalui tahapan penyuluhan pengenalan dan pemilahan sampah berbasis 3R, pelatihan pembuatan dan pengeditan video kampanye, serta perlombaan video edukatif karya santri. Hasil kegiatan menunjukkan adanya peningkatan pemahaman santri terhadap konsep 3R, perubahan perilaku dalam praktik pemilahan sampah, serta meningkatnya partisipasi dan kreativitas santri dalam menyampaikan pesan edukasi lingkungan melalui media video. Pemanfaatan video sebagai media kampanye terbukti efektif dalam meningkatkan keterlibatan santri dan memperkuat kesadaran kolektif di lingkungan pesantren. Kegiatan ini dapat disimpulkan bahwa pendekatan pemberdayaan partisipatif berbasis kampanye video berpotensi menjadi strategi edukasi lingkungan yang efektif dan berkelanjutan dalam mendukung pengelolaan sampah di lingkungan pondok pesantren.
