Abstract

Malaria diagnostic automation faces critical challenges, including severe class imbalance with ratios of up to 54:1, limited datasets containing 200 to 500 images, and computational inefficiency resulting from the need to train separate models for each detection-classification combination. This study developed a multi-model framework with a shared classification architecture that trains classification models once on ground-truth crops and reuses them across all detectors. The framework systematically evaluated three YOLO Medium architectures for parasite detection and six CNN architectures for lifecycle and species classification across four complementary malaria datasets totaling 1,544 microscopy images. Detection achieved mAP@50 scores ranging from 70.84% to 96.27%, with high recall values of 71.05% to 93.12% minimizing missed parasite detections. Classification results demonstrated the importance of dataset-dependent model selection, with parameter-efficient EfficientNet models containing 5.3M to 9.2M parameters consistently outperforming ResNet variants with up to 44.5M parameters. EfficientNet-B1 achieved accuracies of 91.51% on the IML Lifecycle dataset and 98.28% on the MP-IDB Species dataset, while EfficientNet-B0 achieved 86.45% on the multi-patient MD-2019 dataset. ResNet50 achieved 96.13% accuracy on severely imbalanced MP-IDB Stages dataset. Focal Loss optimization with alpha = 1.0 and gamma = 1.5 enabled robust minority-class performance, achieving F1-scores between 0.44 and 1.00 on ultra-minority classes and demonstrating effective handling of class imbalance. The compact models, with sizes ranging from 46 MB to 89 MB, enable practical deployment on resource-constrained hardware.

Abstract

Triangulation is the process of breaking down an n-sided polygon into triangles and it is necessary in deciding the optimal count and the position of guards in the Art Gallery Problem (AGP) There is a theoretical limit that has been established which states that the number of required guards needed to keep an eye on such a polygon is ⌊n/3⌋ and this research considers this as the limit. Among various triangulation methods, Ear Clipping and Minimum Weight are two primary approaches frequently used to achieve optimal solutions. Nonetheless, its comparison with other methods, more particularly the amount of guards required for the maximum theoretical figure, is still a gap in literature. The aim of this research is to create an AGP simulation program and test it against the theoretical upper bound, determining the number of guards required. 228 simple polygons with vertices varying between 10 and 110 were utilized in this research. The polygons were classified into three groups based on the ratio of convex to concave vertices: less concave vertices, equal amount of concave and convex vertices and vice versa. Result study shows that the Ear Clipping method is significantly superior to Minimum Weight in reducing guard requirements. Practically speaking, these advancements are important for the design of engineering systems such as surveillance systems and the surveillance of public spaces. In the context of building security system design and monitoring of large areas, these conclusions are of utmost importance.

Abstract

Pengelolaan energi yang efisien sangat krusial bagi fasilitas berskala besar seperti bandar udara untuk mencegah pembengkakan biaya operasional dan mendukung keberlanjutan. Namun, urgensi ini belum terakomodasi dengan baik di Bandara Sultan Thaha Jambi, di mana pencatatan konsumsi listrik, air, dan bahan bakar masih mengandalkan spreadsheet manual yang terpisah. Pendekatan konvensional ini memicu inefisiensi tinggi, rentan terhadap kesalahan (human error), menyulitkan pelacakan historis, dan memperlambat evaluasi efisiensi oleh pihak manajemen. Penelitian ini bertujuan untuk menganalisis kebutuhan dan merancang purwarupa Energy Management Information System (EMIS) sebagai solusi digitalisasi tata kelola energi. Pendekatan yang digunakan adalah metode Prototype, yang dibatasi pada tahapan Communication, Quick Plan, Modelling Quick Design, dan Construction of Prototype. Kebutuhan sistem dimodelkan melalui Unified Modeling Language (UML) dan Entity Relationship Diagram (ERD), sementara purwarupa antarmuka (user interface) dikonstruksi secara interaktif menggunakan Figma. Hasil penelitian ini adalah high-fidelity prototype yang memfasilitasi formulir pencatatan dengan validasi otomatis, modul manajemen data master dan anggaran, serta dashboard pemantauan terpusat untuk memvisualisasikan tren energi secara real-time. Rancangan ini menghasilkan dokumen acuan (blueprint) teknis yang siap diimplementasikan untuk mengubah proses operasional manual menjadi manajemen energi terintegrasi berbasis data.

Abstract

Pengelolaan pengetahuan di lingkungan Dinas Komunikasi dan Informatika Provinsi Jambi masih menghadapi berbagai kendala, di antaranya dokumentasi yang belum terpusat, pengetahuan tacit pegawai yang berisiko hilang akibat rotasi atau mutasi, serta proses pencarian informasi yang tidak efisien. Kondisi ini menghambat efektivitas kerja dan koordinasi antar Organisasi Perangkat Daerah (OPD) dalam mendukung implementasi Sistem Pemerintahan Berbasis Elektronik (SPBE). Penelitian ini bertujuan untuk mengimplementasikan Knowledge Management System (KMS) berbasis website yang mampu mengelola pengetahuan secara terpusat di Dinas Komunikasi dan Informatika Provinsi Jambi serta memfasilitasi koordinasi konseptual antar OPD. Sistem dikembangkan menggunakan framework Laravel dengan metode Agile Scrum melalui tiga sprint dalam periode Mei hingga Juni 2026, serta mengacu pada kerangka Knowledge Management System Life Cycle (KMSLC) sebagai landasan pengelolaan pengetahuan. Sistem yang dibangun mendukung enam peran pengguna yaitu Super Admin, Admin OPD, Pakar Internal, Pakar Eksternal, Pimpinan, dan Pegawai OPD, dengan fitur utama meliputi manajemen pengetahuan, validasi pengetahuan, manajemen pengguna, manajemen kategori, dan permintaan pengetahuan antar OPD. Pengujian dilakukan menggunakan metode User Acceptance Testing (UAT) dengan pendekatan Blackbox Testing yang melibatkan tujuh responden dari lingkungan Diskominfo Provinsi Jambi. Hasil pengujian menunjukkan persentase keberhasilan sebesar 100% dari 520 skenario pengujian yang mencakup seluruh peran pengguna, melampaui ambang batas penerimaan sebesar 80%. Dengan demikian, sistem dinyatakan diterima dan berfungsi sesuai kebutuhan pengguna serta berpotensi mendukung peningkatan kualitas tata kelola pengetahuan di lingkungan Pemerintah Provinsi Jambi.
