Abstract

This study developed an integrated evaluation application using a User-Centered Design (UCD) approach combined with user-centered prototyping via Figma, aiming to improve academic service management in educational institutions. The application focused on four main features: service request submission, complaint reporting, lecturer evaluation, and a knowledge base for self-service solutions. Requirements were gathered through questionnaires and interviews with students, lecturers, and faculty leaders to ensure the design met user needs. The prototype was iteratively refined based on quantitative and qualitative evaluations using Likert scale questionnaires. Results showed high user satisfaction with an average score of 4.41, indicating excellent usability, visual appeal, and feature relevance. Thematic analysis highlighted key themes of ease of use, interface consistency, and system security. The integrated UCD and Figma prototyping approach proved effective in producing an adaptive, interactive, and user-friendly application design that supports continuous improvement in academic services.

Abstract

Penelitian merupakan suatu langkah yang dilakukan untuk mengembangkan ilmu pengetahuan dan mencari kebenaran. Dasar dalam melakukan penelitian adalah membaca dokumen penelitian sebelumnya. Namun, pencarian dokumen penelitian yang saling berhubungan seringkali membutuhkan banyak waktu. Maka, dibutuhkan pemodelan topik yang dapat mengelompokkan dokumen  berdasarkan topiknya agar membantu peneliti dalam melaksanakan tugasnya. Penelitian ini menggunakan metode Latent dirichlet allocation untuk memodelkan topik dalam dokumen, dan menggunakan perhitungan nilai coherence untuk menentukan jumlah topik yang akan dimodelkan. Hasil analisis menunjukkan bahwa pemodelan topik dengan metode Latent dirichlet allocation berhasil membagi 340 dokumen tesis dalam 5 topik utama dengan nilai coherence yaitu 0.445. Karakteristik yang terdapat dalam tiap topik merupakan bidang kajian tertentu yaitu sistem informasi, kebakaran lahan, bioinformatika, pengolahan citra, dan robotika. Hasil yang didapatkan menunjukkan metode LDA telah berhasil mengelompokkan dokumen dalam kesamaan topik atau kajian tertentu.

Abstract

Rapid peri-urban development in Indonesia, particularly in metropolitan buffer areas such as Bogor Regency, has intensified land use change and increased vulnerability to hydrometeorological disasters. Parung Panjang Subdistrict faces significant environmental pressure from settlement expansion, industrial activity, and mining, which contribute to increased surface runoff, reduced infiltration capacity, and land instability. This study aims to develop and validate a Geographic Information System (GIS)-based model for flood and landslide vulnerability mapping to support sustainable spatial planning at the subdistrict scale. The analysis integrates remote sensing, topographic, and climatic data, while vulnerability weights were determined using the Analytical Hierarchy Process (AHP) and combined through a weighted overlay approach to produce flood, landslide, and multi-hazard vulnerability maps. Model validation was conducted using a confusion matrix, resulting in an Overall Accuracy of 88.4% and a Kappa coefficient of 0.84, indicating strong agreement. The developed flood vulnerability map was further implemented in a web-based GIS platform and functionally tested, achieving a 95% success rate. The findings show that high flood vulnerability is concentrated in low-elevation areas with high moisture indices and dense built-up land use, while multi-hazard zones identify priority areas for mitigation. This study demonstrates the integration of validated multi-hazard spatial modeling with web-based implementation, providing a practical decision-support tool for local disaster mitigation and spatial planning.
