Abstract

Ultraviolet (UV) rays can negatively affect the skin and increase the risk of developing skin cancer especially if it occurs throughout childhood and adolescence. For teenagers, especially those who are often active outdoors, use of sunscreen is very important in order to avoid premature aging and various harmful effects of UV radiation. The use of inappropriate products will hamper the sunscreen's ability to protect skin thoroughly and may cause side effects such as acne or irritation. There are many types and brands of sunscreen products for each skin type, as well as various product criteria that are also considered by teenagers in choosing the best sunscreen product. Role of information technology can help the process of determining the best sunscreen products quickly and precisely, one of which is Decision Support System. The method used is ROC method to determine the weight value of criteria and sub-criteria, and SAW method to determine the final value in ranking alternatives. The data source of this research was obtained by distributing questionnaires to 103 respondents who were teenagers in Palembang City. This study uses 8 alternatives and 8 criteria, namely registered BPOM (C1), acne skin condition (C2), skin type suitability (C3), composition (C4), price (C5), weight (C6), weight suitability to price (C7), and texture (C8). Based on the ranking results, the highest preference value for oily skin type is 0.802, dry skin type is 0.782, normal skin type is 0.788, sensitive skin type is 0.790, and combination skin type is 0.788. All of these skin types have the same alternative with the highest preference value for each skin type, namely alternative A1 (Azarine Calm My Acne Sunscreen Moisturizer SPF 35 PA+++).

Abstract

Sektor pertanian dan perkebunan merupakan mata pencaharian utama di Desa Ibul Besar 1 Provinsi Sumatera Selatan. Berdasarkan analisis situasi, diketahui bahwa petani kurang memperoleh keuntungan akibat tingginya biaya produksi dan kurangnya pendapatan dari hasil panen. Pelibatan pemuda desa dalam pemasaran digital diharapkan dapat meningkatkan pendapatan petani dengan memangkas rantai distribusi yang selama ini masih bergantung pada koperasi atau tengkulak. Tantangannya adalah rendahnya pengetahuan pemuda desa dalam memanfaatkan media sosial dan Platform e-commerce sebagai sarana pemasaran produk. Upaya Peningkatan Pengetahuan Pemuda Desa dalam Pemasaran Online Hasil Tani Menggunakan Media Sosial dan Platform E-commerce dilaksanakan dengan teknis pelatihan dan praktik Pemasaran menggunakan Media Sosial (Instagram dan Tiktok) dan E-commerce (Shopee dan Tokopedia) serta Editing Foto dan Video (PixelLab, Snapseed, dan CapCut) menggunakan perangkat smartphone. Kegiatan berhasil meningkatkan pengetahuan 15 pemuda dan 2 perangkat desa dibuktikan dengan kenaikan nilai rata-rata, perangkingan data dan uji wilcoxon matched-pairs terhadap hasil pre-test dan post-test peserta.

Abstract

The rising number of reviews for the Google Gemini app on the Google Play Store reflects diverse user opinions regarding the performance of this AI-based application. To identify sentiment patterns, this research conducted a comparative study of three classification algorithms—Support Vector Machine (SVM), Naive Bayes, and Random Forest—using 14,479 raw reviews collected through scraping. These reviews then went through several preprocessing steps, including case folding, text cleaning, tokenization, normalization, stopword removal, and stemming. After being labeled based on ratings, the dataset formed a highly imbalanced class distribution, consisting of 11,252 positive reviews and 1,571 negative reviews, and was subsequently split using the Hold-Out method with an 80% training and 20% testing ratio. Evaluation using the Confusion Matrix along with accuracy, precision, recall, and F1-score metrics showed that SVM achieved the best performance, producing 91% accuracy, 93% precision, 97% recall, and a 95% F1-score, outperforming Random Forest and Naïve Bayes, which each reached 90% accuracy. Overall, these results highlight SVM as the most effective algorithm for classifying sentiment in Google Gemini reviews, while the predominance of positive feedback suggests a relatively high level of user satisfaction, although model performance on the minority (negative) class remains a challenge due to data imbalance.

Abstract

Indonesia’s rapid e-commerce growth has produced a vast volume of user reviews, yet their use for insight extraction remains limited—particularly for the Bukalapak platform. This study compares the performance of Naïve Bayes and Support Vector Machine for sentiment classification on 10,000 Bukalapak reviews. The workflow includes text preprocessing (cleaning, case folding, tokenization, stopword removal, and stemming) and feature extraction using Term Frequency–Inverse Document Frequency (TF-IDF; max_features = 10,000). Evaluation employs 10-fold cross-validation with accuracy, precision, recall, and F1-score, complemented by a paired t-test for significance. Results show SVM outperforming NB (accuracy 84.48% vs. 83.96%; F1 0.8253 vs. 0.8205) with better consistency (standard deviation ±1.08% vs. ±1.24%). The t-test confirms a significant difference (p = 0.019), with SVM’s advantage most evident for the negative class (precision 0.80 vs. 0.78). Both models underperform on the neutral class due to severe class imbalance. These findings provide empirical evidence for algorithm selection in Indonesian e-commerce sentiment analysis and open avenues for future research using deep learning and class-imbalance handling techniques.
