Abstract

TPQ Al-Mubaarok, an institution for Quranic learning located in Surabaya, is currently facing challenges in managing student data. Presently, information regarding the students is manually recorded in logbooks, posing a hindrance for the administrators of TPQ Al-Mubaarok to efficiently manage and analyze data. In order to address this issue, we aim to develop a web-based system that facilitates the digital recapitulation process of data. This endeavor begins with conducting field surveys to understand user needs. Subsequently, we proceed to the system design phase and interface design to cater to these needs. System implementation follows the design phase, where we integrate all planned features into a functional system. Next, we conduct system trials involving the authors and the main users of the system, the ustadz/ustadzah. These trials are conducted to ensure that the system operates smoothly and meets user requirements. Finally, we evaluate user satisfaction with the system, particularly from the perspective of the ustadz/ustadzah. The implementation of this system is expected to provide significant benefits, including expediting the registration process for new students, facilitating access to information regarding donations, and providing facilities for managing and summarizing student data more efficiently

Abstract

Abstrak - Manufaktur Energi Nusantara merupakan perusahaan jasa di bidang otomotif yang membutuhkan sistem digital untuk mendukung operasional dan pengambilan keputusan bisnis. Permasalahan utama yang dihadapi adalah pencatatan data penjualan yang masih manual, sehingga menyulitkan proses rekapitulasi dan perencanaan stok. Penelitian ini bertujuan membangun website prediksi penjualan menggunakan metode Seasonal Autoregressive Integrated Moving Average (SARIMA). Data yang digunakan berupa transaksi penjualan produk dan jasa konversi motor bensin ke listrik dari Januari 2021 hingga Januari 2024. Website dikembangkan dengan PHP dan CSS di Visual Studio Code. Model terbaik yang diperoleh adalah SARIMA (2,0,2)(0,0,1)[12], dengan nilai Mean Absolute Percentage Error (MAPE) sebesar 14,32%, yang menunjukkan akurasi prediksi dalam kategori baik. Sistem ini memungkinkan pengguna memasukkan data baru dan memperoleh hasil prediksi secara real-time. Hasil penelitian menunjukkan bahwa metode SARIMA dapat digunakan secara efektif untuk memprediksi pola penjualan yang bersifat musiman. Dengan adanya website prediksi ini, perusahaan dapat meningkatkan efisiensi operasional dan mendukung keputusan bisnis berbasis data. Kata kunci— Website, SARIMA, Prediksi, Penjualan, Akurasi
