Abstract

Abstract: Obesity is an escalating global health concern, with unhealthy lifestyle patterns contributing significantly to its development. This study aims to evaluate and compare three clustering techniques for categorizing lifestyle patterns and obesity-related factors: K-Means, Agglomerative Clustering, and Gaussian Mixture Model (GMM). The data used in this study is sourced from the Food Nutrition dataset, which includes variables such as dietary habits, physical activity, and socio-economic status. The three clustering methods were assessed using evaluation metrics such as Silhouette Score, Davies-Bouldin Index (DBI), and Calinski-Harabasz Index (CHI). The findings revealed that K-Means exhibited the best performance in terms of cluster separation with a Silhouette Score of 0.5559, while GMM showed better flexibility in handling more complex data. Although Agglomerative Clustering produced acceptable results, it had a higher overlap between clusters compared to the other methods. This study offers valuable insights into selecting the most appropriate clustering technique based on the data characteristics. Keywords: agglomerative; clustering; GMM; k-means; lifestyle patterns; obesity Abstrak: Obesitas menjadi masalah kesehatan yang semakin meningkat di seluruh dunia, dengan pola hidup yang tidak sehat berperan besar dalam perkembangannya. Penelitian ini bertujuan untuk membandingkan tiga metode clustering dalam mengelompokkan pola gaya hidup dan faktor yang memengaruhi obesitas, yaitu K-Means, Agglomerative Clustering, dan Gaussian Mixture Model (GMM). Data yang digunakan diperoleh dari dataset Food Nutrition yang mencakup informasi terkait pola makan, aktivitas fisik, serta faktor sosial-ekonomi. Ketiga metode tersebut diuji dengan menggunakan beberapa metrik evaluasi, seperti Silhouette Score, Davies-Bouldin Index (DBI), dan Calinski-Harabasz Index (CHI). Hasil penelitian menunjukkan bahwa K-Means memiliki kinerja terbaik dalam hal pemisahan klaster, dengan nilai Silhouette Score sebesar 0.5559, sementara GMM lebih fleksibel dalam menangani data yang lebih kompleks. Meskipun Agglomerative Clustering memberikan hasil yang dapat diterima, tumpang tindih antar klaster lebih besar dibandingkan dengan kedua metode lainnya. Penelitian ini memberikan pemahaman yang lebih baik mengenai pemilihan metode clustering yang tepat berdasarkan karakteristik data yang digunakan.

Abstract

Perkembangan teknologi Generative AI telah membawa kemajuan pesat dalam pembuatan gambar berbasis teks, dengan DALL-E 3 dan Midjourney sebagai dua model terdepan. Penelitian ini bertujuan untuk menganalisis dan membandingkan akurasi visual hasil gambar dari kedua model menggunakan metrik Frechet Inception Distance (FID). Lima jenis prompt teks dipilih secara sistematis berdasarkan kategori anjing ras tertentu, dan setiap model menghasilkan 50 gambar yang dibandingkan dengan gambar acuan dari dataset Stanford Dogs. Hasil penelitian menunjukkan bahwa DALL-E 3 memiliki rata-rata skor FID sebesar 19.85, sedangkan Midjourney sebesar 28.42, yang berarti DALL-E 3 menghasilkan gambar yang lebih mendekati visual nyata. Uji statistik menggunakan Independent Sample t-Test menunjukkan adanya perbedaan signifikan antara kedua model. Dengan demikian, DALL-E 3 lebih cocok untuk kebutuhan yang menuntut realisme visual, sedangkan Midjourney lebih unggul dalam eksplorasi artistik.

Abstract

The rapid development of visual platforms such as Pinterest necessitates a comprehensive understanding of how functional and emotional aspects jointly influence users’ perception and engagement. This research addresses the gap in user experience (UX) evaluation of visually rich applications by examining the effects of Pragmatic Quality, Hedonic Quality-Stimulation, and Hedonic Quality Identity on the perceived Attractiveness of the Pinterest application. A quantitative approach was employed using the 28-item AttrakDiff instrument, based on data collected from a final sample of 524 valid respondents, predominantly aged 18–25 years, and using Pinterest several times a week. The data analysis was conducted using Partial Least Squares Structural Equation Modeling (PLS-SEM) with the aid of SmartPLS to examine the relationships among latent variables. The findings demonstrate that the structural model exhibits a high level of explanatory capability, with an R² value of 0.684. With all three UX dimensions exerting positive and statistically significant effects on Attractiveness. PQ shows the strongest influence (path coefficient = 0.457), followed by HQS (0.391) and HQI (0.112). These findings confirm that functional usability remains the primary driver of attractiveness on Pinterest, while hedonic qualities play a complementary role in enhancing user experience. Practically, this research suggests that designers and developers of visual platforms should prioritize efficient functionality while maintaining stimulating and identity-supporting elements to improve overall user appeal.

Abstract

In Indonesia, including in East Java Province, infectious diseases such as Dengue Fever (DHF) and Human Immunodeficiency Virus (HIV) remain public health concerns. Incidence patterns vary by region and time of year. Variations in temporal patterns among districts and cities may lead to suboptimal identification of priority intervention areas when analyses rely solely on absolute case counts. This study aims to analyze the temporal patterns of DHF and HIV case distribution in East Java Province during the 2018–2024 period in order to cluster regions based on similarities in case dynamics over time.The analysis was conducted using a time series clustering approach to group districts and cities according to the similarity of their case development patterns. Temporal similarity was measured using the Dynamic Time Warping method and subsequently clustered using Hierarchical Clustering. Prior to analysis, the data were normalized using the Z-score method to minimize the influence of differences in case scale among regions. The results show that the temporal patterns of DHF and HIV cases were each classified into three main clusters. Cluster quality evaluation using the Silhouette index yielded a value of 0.408 for DHF, indicating a relatively clear cluster structure, whereas a value of 0.197 was obtained for HIV, suggesting a weaker cluster structure due to the complexity and heterogeneity of regional-level case data. Nevertheless, the resulting clusters still provide preliminary information on variations in temporal patterns. The identified clusters represent regions with stable, fluctuating, and increasing case patterns. Several urban areas, such as Pasuruan City, Probolinggo City, and Banyuwangi Regency, tend to belong to clusters with relatively high case levels for more than one disease, indicating challenges in disease control within these regions. These findings provide an initial overview of the temporal dynamics of DHF and HIV cases in East Java, which may serve as supporting evidence for region- and time-based disease control planning.

Abstract

A communication crisis and public trust that is not managed properly will become a serious threat to institutions because it affects the image and reputation of the organization, including becoming a serious threat to higher education institutions that can impact public trust and organizational sustainability. This study aims to analyze the implementation of effective communication strategies in the era of social media based on SWOT analysis in restoring the reputation of higher education institutions and identifying factors that determine the success of image restoration campaigns. The study uses a qualitative approach with a case study method at a state university in Kalimantan during the period of July-August 2025. Data was collected through crawling using the Brand24 media monitoring application with analysis of social media content, websites and online news portals (via Instagram and TikTok), monitoring of public sentiment using the Brand24 application, and analysis of engagement metrics. Data analysis used triangulation techniques to validate findings from various data sources. The implementation of measurable communication strategies through social media showed significant results with a 71% increase in positive public sentiment and a decrease in negative public sentiment to 4%. On the Instagram social media platform, it achieved an engagement rate of 140.1% with a total reach of 422,423 accounts, while TikTok achieved an engagement rate of 672.3% with 777 thousand views. Fact-based counter-issue strategies and promotion of the Tridharma program have proven effective in changing public perception and restoring public trust. Systematic and measurable social media management using a SWOT approach can be an effective tool in restoring the reputation of higher education institutions. The key to success lies in the consistent dissemination of fact-based content, active engagement with stakeholders, and regular sentiment monitoring.
