Abstract

Integrating the Global Vectors for Word Representation (GloVe) Model with Social Network Analysis presents a promising approach for extracting nuanced semantic relationships from Wonderland Indonesia's content reviews. However, the lack of comprehensive studies exploring the effectiveness of this integration, specifically within the context of Wonderland Indonesia's content reviews, necessitates focused research to uncover its potential impact and applications. This study investigates the reception and impact of the "Wonderland Indonesia" video content by Alffy Rev ft. Novia Bachmid (Chapter 1) within the YouTube community using a comprehensive methodology based on CRoss-Industry Standard Process for Data Mining (CRISP-DM), topic analysis, and Social Network Analysis (SNA). Through topic analysis, the content's main themes and narrative elements were identified, shedding light on its storytelling effectiveness. Furthermore, sentiment analysis using Vader was conducted on 2204 out of 24185 posts, revealing that 1369 (92%) exhibited positive sentiment, 427 (31.19%) had neutral sentiment, and 850 (62.09%) contained negative sentiment. Additionally, sentiment analysis using TextBlob was performed on the same subset of posts, with 1369 (40) posts exhibiting positive sentiment, 599 (43.75%) with neutral sentiment, and 730 (53.32%) expressing negative sentiment. Notably, metrics such as toxicity (highest value: 0.90780) and severe toxicity (highest value: 0.95021) exhibited varying prominence within the analyzed content. These findings enable targeted interventions and content moderation strategies to promote healthier online discourse. The SNA uncovered intricate social dynamics and interaction patterns among viewers, emphasizing the video's ability to foster engagement and community interaction. This study underscores the significance of creative storytelling and community engagement strategies in digital content creation, with implications for audience participation and community development within the digital sphere. Future research could explore the longitudinal effects of such content strategies on audience retention and community engagement.

Abstract

Poverty is a complex problem that hampers socio-economic development in Indonesia, especially in Central Java Province, which encounters significant challenges, with a poverty rate reaching 10.77% in 2023. This study aims to identify spatial patterns of poverty in 35 districts/cities in Central Java Province by grouping areas based on the number of poor individuals reported by the Central Java Province Statistics Agency (BPS) in 2023. The Density-Based Spatial Clustering of Applications with Noise (DBSCAN) algorithm groups districts/cities based on poverty data density with optimized parameters to produce statistically significant clusters. The results of the analysis reveal four clusters, specifically cluster 0 (moderate poverty), cluster 1 (high poverty), cluster 2 (very high poverty), and cluster 3 (low poverty). Model validation was executed using the Silhouette Score (0.447) and Davies-Bouldin Index (0.441), which showed the validity of the clustering. This study is anticipated to provide strategic implications for the Central Java Provincial Government in formulating more effective poverty alleviation policies, such as resource allocation adjusted to each cluster's characteristics. In addition, this study enables future exploration of additional socio-economic factors influencing poverty, such as the Human Development Index, education, health, infrastructure, resource accessibility, and comparative analysis of clustering algorithms for enhanced accuracy.

Abstract

Perkembangan industri e-commerce di Indonesia belakangan ini dibayangkan pada fenomena meningkatnya keluhan konsumen terkait kebijakan biaya layanan yang dinilai kurang transparan, termasuk indikasi adanya praktik pola gelap . Penelitian ini bertujuan mengkaji persepsi konsumen terhadap isu tersebut melalui pendekatan analisis sentimen berbasis machine learning dan deteksi pola manipulatif. Data penelitian diperoleh dari ulasan pengguna di platform media sosial X yang kemudian diproses melalui serangkaian tahapan text mining meliputi pembersihan data, tokenisasi, stopword removal , dan stemming . Analisis sentimen menggunakan algoritma Support Vector Machine (SVM) menunjukkan hasil yang signifikan, dimana 55-78% ulasan di platform ketiga e-commerce (Shopee, Tokopedia, Lazada) tergolong negatif. Analisis TF-IDF mengidentifikasi kata kunci seperti "biaya", "layan" (layanan), dan "mahal" sebagai istilah paling dominan dalam ulasan negatif. Model SVM menunjukkan kinerja yang cukup baik dengan akurasi mencapai 87% dalam mengklasifikasikan sentimen negatif. Lebih lanjut, analisis tematik terhadap ulasan negatif berhasil mengidentifikasi indikasi pola gelap , khususnya dalam kategori biaya tersembunyi (biaya tersembunyi) dan menyelinap ke keranjang (penambahan produk tanpa disadari) yang muncul secara konsisten di semua platform. Temuan ini tidak hanya menegaskan adanya pola manipulatif yang berulang dalam industri e-commerce Indonesia, tetapi juga menegaskan urgensi bagi para pelaku industri untuk meningkatkan transparansi dalam kebijakan biaya. Secara praktis, hasil penelitian ini dapat menjadi bahan pertimbangan penting bagi regulator dalam merumuskan kebijakan perlindungan konsumen di era digital yang lebih komprehensif.
