Abstract

Indonesia is ranked 77th in the world in electronic-based government systems, especially the City of Plembang is ranked 89th regarding the evaluation of smart city improvement in Indonesia. One of the latest applications used in the past year is the SIDEMANG application, which is an information system that has the use and purpose of facilitating access to administrative services related to personal and agency licensing files online at the village and sub-district levels in Palembang city, but this is also not free from obstacles, especially internet signals. Therefore, an analysis is needed related to the implementation of Information Systems, to assess the success of applications that have been implemented, especially government digital services. DeLone and McLean Information System Success Model is used, to see the significant factors that cause the success of Information System implementation. The data analysis method used in this research is quantitative because the data collected is in the form of numbers and will be analyzed using the SmartPLS application statistical technique, using a sample size of 97 respondents. The results showed that the information quality factor was not significant to the intention or use of the application, the system quality factor was not significant to the intention or use of the application, the system quality factor was not significant to user satisfaction, the service quality factor was not significant to user satisfaction. Recommendations for the Palembang City Communication and Information Office are related to the evaluation and improvement of the SIDEMANG application using the DeLone and McLean Model analysis. In particular, improvements to the quality of information that can influence citizens to use the application, improvements to the quality of the system that can invite and satisfy users in using the application, and improvements to service quality factors on citizen satisfaction.

Abstract

Perkembangan teknologi saat ini mempermudah proses belajar bahasa melalui aplikasi seperti Duolingo. Penelitian ini bertujuan untuk memahami persepsi pengguna terhadap Duolingo dengan menggunakan analisis sentimen berbasis VADER (Valence Aware Dictionary and Sentiment Reasoner). Ulasan pengguna dari Google Play Store diproses menggunakan Google Collaboratory, menghasilkan 1.831 data yang dikelompokkan sebagai netral, negatif, dan positif. Hasil analisis menunjukkan akurasi keseluruhan sebesar 98 persen. Model ini efektif dalam mengidentifikasi sentimen netral (presisi 100 persen, recall 97 persen, F1-score 99 persen) dan positif (presisi 99 persen, recall 82 persen, F1-score 99 persen). Namun, model kurang efektif dalam mendeteksi emosi negatif, dengan F1-score 74 persen, recall 82 persen, dan presisi 67 persen, yang menunjukkan adanya kesalahan klasifikasi pada beberapa emosi negatif. Awan kata menunjukkan kata-kata positif seperti "good," "helpful", dan "fun," serta kata-kata negatif seperti "technical problems" dan "learning limitations." Tantangan dalam penggunaan VADER termasuk ketidakmampuan menangani konteks bahasa yang kompleks dan nuansa emosional yang mendalam. Untuk meningkatkan klasifikasi sentimen, penelitian ini merekomendasikan penggunaan VADER bersama Deep-Translator. Kombinasi ini dapat membantu mengidentifikasi sentimen negatif dengan lebih baik dan menangani data dengan berbagai bahasa secara lebih efisien. Tujuan penelitian ini adalah untuk memahami sudut pandang pengguna dan meningkatkan akurasi analisis sentimen, sehingga berkontribusi pada pengembangan aplikasi pembelajaran bahasa yang lebih baik.

Abstract

The socio-political context surrounding the Indonesian Ulema Council's Fatwa No. 83 of 2023, which catalyzed a significant consumer shift, necessitates an accurate measure of public sentiment toward alternative local brands like Almaz Fried Chicken. Analyzing real-time consumer discourse on the challenging TikTok platform, the study utilized a final dataset of 4,374 unique comments to overcome the inherent problem of dataset imbalance and linguistic informality. The core method involved a seven-stage quantitative approach: data collection, preprocessing, sentiment labeling, data splitting (70:15:15), Random Oversampling (ROS), IndoBERT fine-tuning, and evaluation. This pipeline fine-tuned IndoBERT, a Transformer-based model, integrated with ROS applied exclusively to the training data. Evaluation demonstrated that ROS significantly reduced model bias and enhanced performance: Overall Accuracy increased by 2.0% (from 91% to 93%), and the Macro F1-Score improved by 3.4% (from 0.87 to 0.90). Most critically, the F1-Score for the minority Negative sentiment class surged from 0.78 to 0.84, confirming ROS's effectiveness in accurately detecting critical feedback. These findings provide timely, data-driven insights into brand perception amidst the boycott campaign and establish a robust, reliable IndoBERT-ROS methodology for advanced sentiment monitoring in dynamic social media environments.

Abstract

Flash sale events have become a dominant marketing strategy to trigger rapid purchasing decisions. However, despite the massive growth of e-commerce in Indonesia, it remains unclear whether consumer participation in these events is primarily driven by the thrill of the "hunt" (hedonic) or the rational calculation of discounts (price value), particularly in developing digital markets like Palembang City. This study investigates the determinants of impulsive buying behavior during Flash Sale events on the Tokopedia platform. Drawing upon a modified Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) framework, this study investigates how Hedonic Motivation and Price Value affect Behavioral Intention, and in turn, its effect on Impulsive Buying. A quantitative methodology was applied, leveraging survey responses from 144 participants in Palembang City who had engaged in Tokopedia Flash Sales. Analysis was conducted through Partial Least Squares Structural Equation Modeling (PLS-SEM) with SmartPLS 4 software. Findings reveal that both Hedonic Motivation and Price Value positively and significantly impact Behavioral Intention, with Price Value identified as the most influential predictor. Furthermore, a robust positive relationship was found between Behavioral Intention and Impulsive Buying, confirming that the intention to participate in Flash Sales significantly drives unplanned purchasing behavior. These findings suggest that while hedonic enjoyment is important, the perceived economic benefit remains the primary catalyst for consumers. Practically, platforms can optimize flash sale design by emphasizing perceived savings and enjoyable experience to effectively drive conversion.

Abstract

Promosi institusi pendidikan di era digital menuntut inovasi media yang interaktif, di mana platform metaverse seperti Roblox menawarkan potensi besar untuk pengalaman imersif dan partisipatif yang melampaui media konvensional. Penelitian ini bertujuan untuk merancang dan mengembangkan sebuah game edukasi virtual Kampus Universitas Sriwijaya yang berlokasi di Palembang, yang berfungsi sebagai media promosi dan pengenalan lingkungan kampus yang interaktif bagi calon mahasiswa dan mahasiswa baru. Metode penelitian yang digunakan adalah Multimedia Development Life Cycle (MDLC) yang mencakup enam tahapan sistematis: Concept, Design, Material Collecting, Assembly, Testing, dan Distribution. Pengujian produk dilakukan melalui pengujian menggunakan User Experience Questionnaire (UEQ) yang disebarkan kepada 200 responden mahasiswa baru Universitas Sriwijaya. Hasil penelitian ini adalah sebuah game edukasi virtual yang fungsional dan telah berhasil dipublikasikan di platform Roblox, lengkap dengan visualisasi 3D lingkungan kampus, fitur eksplorasi, dan interaksi multipemain. Hasil testing menggunakan UEQ menunjukkan bahwa game ini mendapatkan evaluasi sangat positif pada keenam dimensi (Daya Tarik, Kejelasan, Efisiensi, Ketepatan, Stimulasi, dan Kebaruan), dengan nilai rata-rata tertinggi pada aspek Daya Tarik (1,90). Disimpulkan bahwa metode MDLC berhasil diterapkan secara efektif untuk membangun game edukasi ini, dan produk yang dihasilkan terbukti sangat diterima dengan baik oleh pengguna sebagai media pengenalan kampus yang inovatif dan menarik.
