Abstract

Graduates of Vocational High Schools (SMK) consistently contribute the most to Indonesia's Open Unemployment Rate (TPT), reaching 8.63% as of August 2025. A major issue is students' limited ability to develop relevant digital personal branding aligned with modern recruitment standards, such as having an attractive and accessible online Curriculum Vitae (CV). This community service project (PkM) aims to equip 12th-grade students at SMK Al-Amin Mojowuku, Kedamean, Gresik, with skills to create instant website-based CVs using three free tools: generative AI (DeepSeek), image hosting service (ImgBB), and HTML publishing platform (Tiiny.host). Conducted offline on April 28, 2026, with 28 participants, the workshop employed project-based learning combined with AI-assisted learning. The activity involved needs analysis, module development, workshops through lectures and practical exercises, and output evaluation. Results showed all participants successfully published personal CV websites with various themes such as manga comics, anime, and floral motifs. Quantitative indicators included a 100% task completion rate, high active engagement, and positive feedback on material relevance. This activity effectively improved digital literacy, creativity and prepared students for digital-focused recruitment processes

Abstract

This research aims to improve the accuracy of stock price prediction through the application of Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU) methods, focusing on stocks from the Composite Stock Price Index (CSPI) referred to as the IDX Composite. The research process includes comprehensive steps, including data collection and preprocessing, dataset creation with emphasis on stock closing prices, and division of the dataset into training and test data. The LSTM and GRU models were designed with a recurrent layer and a Dense layer and then trained for 100 epochs with a batch size of 32. Model evaluation was performed by comparing key metrics such as Root Mean Squared Error (RMSE), Mean Squared Error (MSE), and Mean Absolute Error (MAE) on the test set. The EPOCH-RMSE graph provides an overview of the changes in the RMSE value during training. The best result of the LSTM model was achieved at the 96th epoch with RMSE 40.36, MSE 1385.97, and MAE 30.09, while GRU achieved peak performance at the 92nd epoch with RMSE 37.33, MSE 908.29, and MAE 25.42. In conclusion, GRU can be considered as a more effective option in predicting JCI stock prices based on performance evaluation using various metrics such as RMSE, MSE, and MAE.

Abstract

The development of information technology has encouraged digital transformation in various business sectors, including gold trading businesses. Bintang Emas Kraksaan Store still applies conventional transaction processes, causing limitations in product information delivery, transaction recording, and gold price updates. This study aims to implement a web-based e-commerce information system for gold trading to improve transaction efficiency and digital data management. The system was developed using the Waterfall method, consisting of requirement analysis, system design, implementation, testing, and maintenance stages. The developed system provides several features such as product management, gold price updates, online transactions, user authentication, and sales reporting. System testing was conducted using Black Box Testing and User Acceptance Testing. The results indicate that the system successfully improves transaction efficiency, facilitates digital transaction management, and provides real time gold price information. Based on the User Acceptance Testing (UAT)(UAT)results, the system is considered acceptable and easy to use by users

Abstract

Pencatatan manual sangat menghambat mobilitas petugas koperasi di lapangan. Penelitian ini bertujuan merancang aplikasi koperasi daring berbasis web seluler yang dihubungkan dengan perangkat printer thermal bluetooth melalui perantara aplikasi pihak ketiga. Sampel pengujian secara spesifik melibatkan empat petugas dinas lapangan dan satu admin koperasi. Sistem ini dikembangkan menggunakan metodologi Extreme Programming (XP) oleh satu pemrogram dalam waktu 35 hari. Hasil penelitian menunjukkan bahwa praktik pengujian berkelanjutan mampu menjaga stabilitas koneksi antara aplikasi dan perangkat pencetak. Selain itu, pembagian siklus kerja menjadi beberapa iterasi kecil sangat memudahkan penyesuaian fitur dengan kebutuhan pengguna akhir. Uji coba langsung mengonfirmasi bahwa aplikasi berhasil meningkatkan efisiensi waktu operasional hingga 75%, di mana durasi pelayanan yang sebelumnya memakan waktu sekitar delapan menit secara manual kini dapat diselesaikan dalam waktu kurang dari dua menit untuk proses pengelolaan data simpan pinjam sekaligus pencetakan struk di lokasi. Sebagai simpulan, metode XP terbukti sangat efektif dan efisien untuk menyelesaikan proyek perancangan sistem yang melibatkan integrasi perangkat keras di bawah batasan waktu yang ketat.
