Abstract

Heart disease is one of the leading causes of death worldwide and often goes undetected early. This necessitates a decision support system capable of facilitating rapid and accurate diagnosis. This study aims to develop a heart disease classification system by combining two methods: K-Nearest Neighbors (KNN) and Principal Component Analysis (PCA), in a web-based application using Streamlit. PCA is used to reduce data dimensionality and eliminate less relevant features to improve classification efficiency and performance. Meanwhile, the KNN algorithm is used to determine the class (heart disease or not) based on the proximity of the new data to the labeled data. This study used the heart.csv dataset and was tested using several methods, including accuracy, classification reports, and confusion matrices. The test results showed that the hybrid PCA and KNN model was capable of providing relatively high accuracy and informative visualizations. The best accuracy rate achieved in this study reached 90%, demonstrating the model's effectiveness in classifying data. Using the Streamlit interface, this system is easily accessible and usable by users without requiring special installation. The conclusion of this study is that the combination of PCA and KNN is effective in classifying heart disease efficiently and accurately.

Abstract

This community service program (PkM) strengthened the competitiveness of Kampoenk Snack MSME (Probolinggo) by raising partner empowerment in management (income generating) and marketing (revenue generating). Baseline conditions showed manual operations: inconsistent transaction and cashflow records, low traceability, and limited digital penetration (online sales <20%, rating 4.3 with <30 reviews). The program applied Participatory Action Research (PAR) in five stages: socialization, training, technology deployment, mentoring–evaluation, and sustainability. Interventions were grouped into (1) management–finance digitalization via a simple accounting/recording app, standardized workflows, and monthly profit–loss reporting; and (2) digital marketing automation through marketplace restructuring, improved content, and notification-based e-commerce (WhatsApp Fonnte, Telegram Bot, email marketing, auto-responder), with WhatsApp direct messages as the primary conversion channel. Performance measures included a management regularity checklist, marketplace dashboards for rating and reviews, notification logs, and content insights. Measurement windows were two weeks for content reach and two months for online revenue. Data were triangulated by cross-checking app records, marketplace recaps, transaction evidence, interviews, and observations. Results show management regularity improved to 85%, promotions reached >300 customers, 15 photos and 5 videos reached ~5,000 accounts in two weeks, online revenue rose ~30% (IDR 2.75 million to ~IDR 3.5–4 million/month), and marketplace reputation increased (reviews 28→53; rating 4.3→4.7).

Abstract

Transformasi digital dalam pendidikan nonformal, khususnya lembaga bimbingan belajar (bimble), masih menghadapi tantangan berupa rendahnya pemanfaatan teknologi secara optimal dalam penyajian materi dan penugasan pembelajaran. Kondisi ini berdampak pada keterbatasan interaksi, partisipasi, dan efektivitas evaluasi belajar siswa. Penelitian ini bertujuan untuk menganalisis implementasi inovasi e-materi dan penugasan interaktif berbasis teknologi serta mengevaluasi dampaknya terhadap kualitas pembelajaran di lembaga bimbingan belajar. Metode penelitian yang digunakan adalah mixed methods dengan pendekatan studi kasus dan survei. Data kualitatif diperoleh melalui wawancara, observasi, dan analisis dokumen, sedangkan data kuantitatif dikumpulkan menggunakan kuesioner berskala Likert yang melibatkan 50 siswa. Hasil penelitian menunjukkan bahwa penerapan e-materi berbasis multimedia meningkatkan kemudahan akses dan daya tarik materi pembelajaran, sementara penugasan interaktif mampu mendorong partisipasi aktif siswa serta memperjelas instruksi tugas. Analisis kuantitatif memperlihatkan skor tertinggi pada aspek kemudahan akses e-materi dan kejelasan instruksi penugasan, meskipun mekanisme umpan balik masih perlu ditingkatkan. Secara keseluruhan, transformasi digital terbukti efektif dalam meningkatkan kualitas pembelajaran bimble apabila didukung oleh desain materi yang kontekstual, kesiapan pengajar, serta infrastruktur teknologi yang memadai.
