Rendahnya kesiapan siswa SMKN 3 Buduran Sidoarjo dalam berwirausaha disebabkan oleh pembelajaran kewirausahaan yang masih bersifat teoritis dan belum kontekstual dengan jurusan produktif. Untuk mengatasi permasalahan tersebut, dilakukan program pengabdian masyarakat yang bertujuan meningkatkan kompetensi kewirausahaan siswa secara komprehensif, mencakup aspek kognitif, psikomotorik, dan afektif. Metode pelaksanaan meliputi pelatihan berbasis praktik yang terintegrasi dengan Teaching Factory dan pendekatan project-based learning selama 10 hari. Rangkaian kegiatan mencakup pembekalan teori, workshop, simulasi, pendampingan konsultatif, penguatan kelembagaan usaha sekolah, serta kolaborasi dengan perguruan tinggi dan mitra industri. Hasil evaluasi menunjukkan peningkatan signifikan kompetensi siswa, dengan nilai rata-rata pre-test meningkat dari 61,0 menjadi 95,8 pada post-test. Selain itu, kegiatan ini menghasilkan rencana usaha siswa, prototipe produk inovatif, dan terbentuknya unit kewirausahaan sekolah sebagai wadah pengembangan bisnis nyata. Program ini terbukti memberikan manfaat langsung bagi siswa, sekolah, dan mitra, serta memperkuat sistem pendidikan vokasi sebagai model pembelajaran kewirausahaan berbasis kompetensi yang efektif. Disarankan agar program serupa direplikasi di sekolah vokasi lain dengan penyesuaian karakteristik lokal.

The rapid expansion of digital banking services in Indonesia has increased the need for continuous monitoring of user satisfaction, particularly through feedback submitted via app reviews. This study analyses user sentiment toward the Livin’ by Mandiri mobile banking application using a deep learning approach. A total of 5,000 user reviews were collected exclusively from the Google Play Store and pre-processed through text cleaning steps such as slang normalization, stemming, and tokenization. Sentiment labels (positive, neutral, negative) were assigned using an Indonesian lexicon-based method, and a Long Short-Term Memory (LSTM) model was trained and evaluated with accuracy, precision, recall, and F1-score metrics. Results indicate negative sentiment dominates (37.6%), with frequent complaints about login failures and slow performance, while the LSTM model achieved 98% accuracy. This study is limited by its single-platform data source, potential linguistic bias in Indonesian user reviews, and the model’s limitations in detecting sarcasm or complex emotions. Nonetheless, the findings demonstrate the applicability of sentiment analysis as a real-time monitoring tool to support feature enhancement and user experience improvements in Indonesian mobile banking services.

The purpose of this study was to analyze the extent to which influencer marketing and electronic word of mouth (E-WOM) simultaneously influence consumer purchasing decisions. This research employed a quantitative approach with a survey method. Data were collected through questionnaires distributed to 100 respondents who had purchased or used cosmetic products after being exposed to influencer marketing and E-WOM, selected using purposive sampling. Data analysis was conducted using multiple linear regression to determine the influence of the independent variables (influencer marketing and E-WOM) on the dependent variable (purchase decision). The findings reveal that influencer marketing and E-WOM significantly affect consumer purchasing decisions, with a combined contribution of 56.9%. This result highlights the novelty of integrating both digital strategies as complementary drivers of consumer behavior in the cosmetic industry, particularly in an era where peer-to-peer communication and digital endorsements increasingly shape purchase intentions. From an academic perspective, this study enriches the literature on digital marketing by demonstrating how the synergy between influencer credibility and electronic word-of-mouth creates a stronger explanatory framework for understanding purchasing decisions. Practically, the findings imply that cosmetic brands should not only optimize influencer collaborations but also design strategies that stimulate authentic consumer engagement to enhance E-WOM, thereby achieving a sustainable competitive advantage in digital marketplaces.
