Abstract

Penelitian ini menggunakan (SLR) terhadap 380 artikel terpilih dan 145 relevan serta memenuhi kriteria inklusi. Artikel-artikel tersebut terdiri dari 6 studi etnomatematika budaya lokal (termasuk artikel spesifik tentang Marapu), 76 penelitian tentang penerapan (PBL) dalam konteks lokal, dan 63 studi mengenai integrasi teknologi digital dalam pembelajaran matematika. Sebaran publikasi menunjukkan peningkatan minat penelitian pada ketiga topik ini dalam dekade terakhir, dengan dominasi studi etnomatematika marapu (4%) diikuti PBL (52%) dan teknologi digital (44%). Artikel dari tahun 2020-2025 terpilih dari Google Scholar, Scopus, dan ERIC untuk menganalisis penguatan etnomatematika Marapu melalui Problem-Based Learning (PBL) dan integrasi teknologi digital dalam pembelajaran matematika. Hasil kajian menunjukkan bahwa budaya Marapu mengandung konsep matematika yang kaya, termasuk pola geometri fractal pada tenun, sistem bilangan adat, dan pengukuran tradisional, yang dapat diintegrasikan ke dalam kurikulum melalui pendekatan PBL berbasis konteks nyata. Analisis mengungkap bahwa PBL efektif meningkatkan keterlibatan siswa dan pemahaman konsep matematika melalui eksplorasi masalah budaya, sementara teknologi digital (seperti tampilan rumah adat 3D dan aplikasi interaktif) berperan penting dalam memvisualisasikan konsep abstrak. Namun, implementasi menghadapi tantangan seperti resistensi terhadap perubahan, keterbatasan infrastruktur teknologi, dan kurangnya pelatihan guru. Temuan utama penelitian ini menawarkan kerangka holistik yang menggabungkan etnomatematika, PBL, dan teknologi digital, dengan rekomendasi praktis berupa pengembangan modul berbasis budaya, pelatihan guru, dan solusi teknologi sederhana untuk daerah terpencil. Studi ini berkontribusi pada pengembangan pedagogi matematika berbasis budaya sekaligus memberikan jalan bagi penelitian lanjutan tentang model evaluasi jangka panjang dan adaptasi pendekatan ini dalam konteks budaya lain.

Abstract

The development of information technology provides opportunities for government agencies to improve data management and public services. The data collection process for uninhabitable houses at the Housing and Settlement Area Office of Southwest Sumba Regency still requires an integrated information system to support data recording, verification, storage, and reporting. This study aims to develop a web-based information system for collecting data on uninhabitable houses to support the management of data at the village and regency levels. The system was developed using the Waterfall software development model, consisting of requirements analysis, system design, implementation, testing, and maintenance. The system was developed using web-based technologies with PHP and MySQL as the database management system. The system, named SIPERATU, provides separate functions for village operators and regency administrators. Village operators can input uninhabitable house data, upload supporting photographs, edit data, and submit data for verification. Regency administrators can review submitted data, verify data, accept or reject submissions, manage verified data, and export data for reporting purposes. The developed system is expected to support more structured, centralized, and efficient management of uninhabitable house data.

Abstract

The management of student organizations in higher education requires accurate, accessible, and traceable information to support activity planning, administration, monitoring, and reporting. At Universitas Stella Maris Sumba, organizational information and activity administration can be consolidated through a web-based monitoring information system so that relevant stakeholders can access current data according to their roles. This study aims to design and develop a web-based student organization monitoring information system using the Laravel framework and MySQL database. The research uses a systems development approach consisting of system requirements analysis, UML-based system design, implementation, and functional and usability testing. System analysis is conducted using the PIECES framework to identify problems in performance, information, economy, control, efficiency, and service. System design employs use case, activity, sequence, class, and entity-relationship models, while the Waterfall model is used as the development method. Laravel is used to implement the application using an MVC architecture and MySQL is used for structured data management. The proposed system provides role-based access to organization data, administrators, activity programs, proposals, accountability reports, monitoring status, and reporting. The empirical testing values, including the number of test scenarios and usability score, should be inserted from the actual test results before publication. The study is expected to support more structured, transparent, and traceable management of student organization activities at Universitas Stella Maris Sumba.

Abstract

Digital images are increasingly used as documentation in educational environments, while image-editing tools make manipulation increasingly accessible. This study analyzes a workflow that combines Error Level Analysis (ELA) and a Convolutional Neural Network (CNN) for preliminary detection of manipulated images using photographs from SD Padedewatu as a case study. The dataset initially consisted of 34 original photographs. Because the supplied photographs did not contain verified manipulation labels, controlled manipulated variants were generated from each source image using copy-move, splicing, and object-erasure operations. The resulting labeled dataset contained 136 images, consisting of 34 authentic and 102 manipulated images. ELA was applied by recompressing each image and visualizing the resulting compression-error differences. A CNN classifier was then trained on ELA representations. To reduce source-image leakage, 24 source-image groups were used for training and 10 source-image groups were reserved for testing, producing 96 training images and 40 testing images. The model achieved 75% test Accuracy, 75% precision, 100% recall, and an F1-score of 85.71%. However, the confusion matrix showed that all test images were predicted as manipulated, including the 10 authentic images. Therefore, the Accuracy value should not be interpreted as evidence of balanced or robust forgery detection. The experiment provides a reproducible local ELA-CNN workflow and identifies dataset balance, sample size, and external validation as important priorities for subsequent research.

Abstract

Selecting high-achieving elementary school students is a multi-criteria decision problem because academic performance alone does not fully represent student achievement. This study proposes a web-based Decision Support System (DSS) to identify outstanding students at Sekolah Dasar Katolik Wikico Kawango using the Simple Additive Weighting (SAW) method. The research design combines system analysis, object-oriented system design using Unified Modeling Language (UML), Waterfall-based development, and black-box functional testing. SAW is applied through criteria identification, criterion weighting, decision matrix construction, normalization by benefit and cost attributes, and calculation of the preference value for each student. The proposed model is intended to make the selection process more structured, transparent, reproducible, and easier to document than a purely manual process. Because the source materials supplied for this drafting stage do not include the school's actual student dataset, criterion weights, or testing records, the numerical ranking results in this manuscript are presented as a validation-ready model, not as empirical findings. The resulting manuscript therefore provides a complete methodological and reporting structure that can be populated with verified school data before submission.
