Abstract

Kemajuan teknologi informasi dan komunikasi menuntut adanya adaptasi dalam dunia pendidikan, termasuk pada jenjang pendidikan anak usia dini. Pengenalan teknologi sejak dini menjadi langkah strategis dalam membentuk kesiapan anak menghadapi era digital. Kegiatan pengabdian ini bertujuan untuk mengenalkan teknologi, khususnya komputer, kepada siswa Taman Kanak-kanak (TK) melalui game edukasi berbasis online. Kegiatan dilaksanakan secara luring di TK Kristen 1 Satya Wacana, Salatiga, dengan melibatkan siswa berusia 5–6 tahun. Metode pelatihan dilakukan dalam beberapa sesi, mencakup pengenalan bagian-bagian komputer, penggunaan mouse, serta pelatihan melalui game edukasi seperti pengenalan huruf, angka, bentuk geometri, dan jenis-jenis kendaraan. Hasil evaluasi menunjukkan bahwa siswa menunjukkan antusiasme tinggi selama pelatihan, serta mulai mengenal komputer sebagai media pembelajaran alternatif selain perangkat yang biasa digunakan di rumah seperti handphone dan tablet. Kegiatan ini membuktikan bahwa pendekatan belajar sambil bermain dengan teknologi dapat meningkatkan minat belajar dan keterampilan dasar siswa dalam menggunakan komputer.

Abstract

Penanganan pengaduan masyarakat sering terhambat oleh proses manual yang tidak terstruktur, menyebabkan respons yang lambat dan hilangnya riwayat penanganan. Penelitian ini mengembangkan dan menerapkan Sistem Informasi Pengaduan Masyarakat berbasis web yang dilengkapi dengan mekanisme automatic ticketing workflow untuk memastikan setiap laporan tercatat, terverifikasi, dan dialirkan ke unit terkait secara otomatis. Sistem dirancang menggunakan arsitektur modular dengan fitur inti berupa pelacakan status tiket, notifikasi otomatis, serta dashboard analitik untuk memantau kinerja penanganan. Metode pengembangan yang digunakan adalah pendekatan waterfall dengan tahapan analisis kebutuhan, desain sistem, implementasi, dan pengujian. Hasil penerapan menunjukkan bahwa otomatisasi alur tiket mampu mempersingkat waktu disposisi, meningkatkan akurasi distribusi laporan, dan memberikan transparansi proses bagi pengguna maupun admin. Pengujian fungsional juga menunjukkan tingkat keberhasilan fitur sebesar lebih dari 95%, menandakan sistem berjalan stabil dan memenuhi kebutuhan operasional. Temuan ini menegaskan bahwa integrasi automatic ticketing dalam sistem pengaduan mampu meningkatkan efisiensi, akuntabilitas, serta kualitas pelayanan publik.

Abstract

This study aims to develop and evaluate a stock price prediction model for Bank Central Asia (BBCA) using a multivariate Long Short Term Memory (LSTM) approach. The model utilizes four key variables from historical stock data open, high, low, and close prices and is compared to a univariate model that uses only the closing price as input. The research process includes data preprocessing, LSTM architecture design, model training over 200 epochs, and performance evaluation using MAE, RMSE, and MAPE metrics. The results demonstrate that the multivariate LSTM model provides higher predictive accuracy, achieving a MAPE of 2.41%, outperforming the univariate model which recorded 2.71%. Moreover, the multivariate model shows better stability across validation and test data, and greater adaptability in capturing market dynamics. Prediction result visualizations support these findings, with the multivariate model producing more consistent forecasts that closely follow actual data. These results suggest that integrating OHLC variables enhances prediction accuracy and model reliability. This study contributes to the advancement of stock price prediction systems based on deep learning and serves as a valuable reference for investors and decision-makers in designing more data-driven investment strategies.

Abstract

This paper examines the role of Digital Support Systems in strengthening vocational education and accelerating sustainable skill development. The study highlights how integrated digital platforms, ranging from adaptive learning systems, virtual simulations, digital assessment tools, and learning analytics, enhance instructional quality, ensure competency alignment with industry demands, and improve learner engagement. The findings show that digital support systems enable more personalized learning paths, real-time performance monitoring, and greater accessibility for diverse learners. Moreover, these systems help vocational institutions respond quickly to evolving labor-market skills, reduce training gaps, and improve long-term workforce readiness. The paper concludes that adopting well-designed digital support systems is essential for building a resilient, future-oriented vocational education ecosystem capable of sustaining continuous skill development in the digital era.

Abstract

The E-Marketplace system is a digital place where sellers and buyers meet virtually, and transactions can be processed safely. E-Marketplace companies are oriented toward consumer-centric products and services and operate and have 24/7 non-stop transaction activities. E-Marketplace system development has become the digital transformation in Information Technology (IT) governance that meets the requirements of a system-based automated control with the application of DevOps principles. This study uses a mixed method approach through questionnaires, interviews, expert judgment, and relevant literature reviews related to the e-Marketplace system and IT governance concepts using the COBIT 2019 framework, which has 11 design factors with 40 IT processes to obtain the most appropriate governance model for e-Marketplace companies. The results were obtained in the form of 6 (six) methods in the IT governance model using the DevOps approach, namely the APO03 – Managed Enterprise Architecture, APO04 – Managed Innovation, BAI04 – Managed Availability and Capacity, BAI06 – Managed IT Changes, BAI11 – Managed Projects, and DSS03 – Managed Problems with a score ≥ 75 and the capability level target is at level 4.
