Abstract

Portal Pendaftaran KIP-Kuliah ITBI merupakan sistem berbasis web yang digunakan dalam proses penerimaan mahasiswa baru jalur KIP-Kuliah. Penelitian ini bertujuan untuk mengevaluasi pengalaman pengguna (user experience) portal tersebut menggunakan metode User Experience Questionnaire Plus (UEQ+). Penelitian menggunakan pendekatan kuantitatif deskriptif dengan teknik stratified random sampling terhadap 122 responden mahasiswa aktif. Instrumen yang digunakan terdiri dari 28 item pertanyaan yang merepresentasikan tujuh skala UEQ+, yaitu attractiveness, efficiency, intuitive use, visual aesthetics, quality of content, trustworthiness of content, dan social interaction. Hasil uji reliabilitas menunjukkan seluruh skala memiliki nilai Cronbach’s Alpha antara 0,93 hingga 0,97 (>0,70), sehingga dinyatakan reliabel. Analisis nilai mean menunjukkan seluruh skala berada pada kategori evaluasi positif dengan nilai tertinggi pada trustworthiness of content (2,15), diikuti social interaction (2,14), efficiency (2,12), quality of content (2,05), visual aesthetics (1,99), attractiveness (1,96), dan intuitive use (1,72). Temuan ini mengindikasikan bahwa aspek kepercayaan terhadap konten dan interaksi sosial menjadi kekuatan utama portal, sementara aspek kemudahan penggunaan masih memerlukan optimalisasi. Secara keseluruhan, Portal Pendaftaran KIP-Kuliah ITBI telah memberikan pengalaman pengguna yang baik, namun perbaikan pada struktur navigasi dan penyederhanaan alur interaksi diperlukan untuk meningkatkan usability secara lebih optimal.

Abstract

This research aims to analyze the development of the Semantic Information Retrieval System (Semantic IRS) approach in e-commerce product search based on descriptions through a literature study of 15 scientific articles consisting of national and international publications. The results of the analysis show that 33% of articles use the semantic IR and dense retrieval approaches as the basis for semantic mapping between queries and product documents. The late interaction and multimodal semantic retrieval approaches were each applied in 27% of articles, indicating an increasing research focus on token-level semantic interaction modeling and the integration of textual and visual information. Additionally, 13% of articles utilized query expansion and semantic relation modeling as supporting methods to improve search relevance. In terms of methodology, 80% of article used a quantitative experimental approach with information retrieval system metric-based evaluation, and 67% of articles adopted neural models. Overall, these quantitative findings indicate that neural model-based Semantic IR, late interaction, and multimodal approaches are the dominant and most relevant directions for handling long and unstructured description-based product searches in modern e-commerce systems.
