Abstract

This study aims to evaluate SMILE at BPJS Ketenagakerjaan Tanjung Morawa Branch using the User Compatibility method which assesses the extent to which the application meets the needs, capabilities, and expectations of users.  This research method involves surveying SMILE users at BPJS Ketenagakerjaan Tanjung Morawa Branch by considering aspects of usability, efficiency, and user satisfaction. Data collection was carried out through questionnaires, interviews, and direct observation of SMILE users at BPJS Ketenagakerjaan Tanjung Morawa. The evaluation results show that SMILE Data and Information Management BPJS Ketenagakerjaan Tanjung Morawa Branch has a high level of user compatibility. Because it shows that all EUCS (End User Computing Satisfaction) independent variables consisting of Content, Format, Accuracy, Timeliness, Ease of Use have a significant relationship with SMILE user satisfaction. The resulting evaluation results and recommendations can serve as guidelines for future development and improvement.

Abstract

Penerimaan Peserta Didik Baru merupakan langkah awal dalam manajemen pelayanan sekolah kepada masyarakat dalam dunia pendidikan. Bagaimana sebuah sekolah melakukan promosi produk dan sekaligus pelayanan prima diawali dari penerimaan peserta didik, selanjutnya siswa/orangtua mendapatkan akses portal. Penelitian ini menggunakan metode waterfall dalam melakukan rancang bangun sistem informasi penerimaan peserta didik baru, metode watefall adalah suatu metode yang merupakan perancangan System Development Life Cycle (SDLC) ,dimana perancangan diawali dengan requirement,design,implementaon,verificaon,dan maintenance. Proses penerimaan peserta didik baru pada lembaga pendidikan sering kali melibatkan banyak dokumen dan proses yang rumit. Oleh karena itu, dibangunlah sistem informasi PPDB berbasis web sebagai solusi untuk meningkatkan aksesibilitas, kecepatan, dan akurasi dalam proses tersebut. Dalam penelitian ini, akan dilakukan studi literatur mengenai PPDB, pengumpulan data terkait persyaratan dan prosedur penerimaan peserta didik baru, perancangan sistem informasi, implementasi sistem, pengujian, dan pembuatan laporan. Sistem informasi PPDB berbasis web ini akan mencakup fitur-fitur seperti pendaftaran online, pengumpulan dokumen secara digital, sistem seleksi dan penilaian calon siswa, serta pengumuman hasil seleksi secara transparan. Dengan adanya sistem informasi PPDB berbasis web yang dirancang dan dikembangkan dalam penelitian ini, diharapkan proses penerimaan peserta didik baru pada lembaga pendidikan dapat menjadi lebih efisien, terstruktur, dan memberikan kemudahan bagi calon peserta didik serta pihak terkait. Sistem ini akan membantu lembaga pendidikan dalam mengelola dan melacak data peserta didik baru dengan lebih baik, sehingga proses penerimaan dapat dilakukan dengan lebih akurat dan efektif..

Abstract

Durian production in Dairi Regency, North Sumatra, fluctuates substantially across quarters, creating uncertainty for harvest planning and distribution. This study develops a lightweight decision-support system that integrates an AutoRegressive Integrated Moving Average (ARIMA) forecasting pipeline with a Streamlit web application. The source dataset contains 41,060 agricultural harvest records from 2020–2024, aggregated into 20 quarterly regional observations. The raw series was non-stationary according to the Augmented Dickey–Fuller test (ADF = −0.449, p = 0.901), while first-order differencing produced a stationary series (ADF = −4.120, p = 0.0009). Automated model search selected ARIMA (4,0,1), with AIC = 401.649 and BIC = 407.624. A chronological 80/20 holdout evaluation on the four quarters of 2024 produced an RMSE of 1.16 tons, MAE of 1.15 tons, and MAPE of 4.33%, recalculated from the reported quarter-level forecasts. The Streamlit implementation integrates data management, stationarity diagnosis, automated parameter selection, and forecast visualization. The results indicate that an interpretable ARIMA baseline can provide useful short-horizon regional forecasts when historical data are limited, although the short series requires cautious generalization and further validation.
