Abstract

This research is conducted to predict the number of visitors to libraries within primary education institutions by employing the Autoregressive Integrated Moving Average (ARIMA) modeling technique. The dataset comprises daily visitor records spanning from January 2023 to December 2024. The forecasting process adopts a time series framework, which includes steps such as data preprocessing, stationarity verification through the Augmented Dickey-Fuller (ADF) test, identification of parameters using Autocorrelation Function (ACF) and Partial Autocorrelation Function (PACF) plots, and the selection of the optimal model based on statistical significance and performance metrics, particularly the Mean Squared Error (MSE). Out of 35 evaluated ARIMA configurations, the ARIMA(2,0,11) model demonstrated the best performance, achieving the lowest MSE score of 789.08 and exhibiting statistically meaningful parameters. Moreover, the model passed the Ljung-Box diagnostic test, confirming that the residuals behave as white noise.The forecasting results for January 2025 show a stable and realistic trend. Compared to baseline methods such as Naïve Forecast, the ARIMA model demonstrates superior performance by effectively capturing data fluctuations. Therefore, ARIMA(2,0,11) is considered effective and accurate in supporting data-driven library service planning for the future.

Abstract

The Kirana Budaya Art Studio is an institution engaged in the preservation of arts and culture through various activities such as dance training and costume rental. However, the manual administration management causes various challenges, such as time efficiency, data accuracy, and limitations in conveying information to the wider community. To overcome these problems, a website-based information system was developed that was designed to support the studio's operational needs. This system was built using the Agile Development method, which allows the development process to be carried out iteratively by involving input from end users on an ongoing basis. This approach ensures that the resulting system can adapt to the dynamic needs of the studio. The main features developed include class registration, schedule management and activity classes, and costume rental. The purpose of this research is to produce a website-based information system using the Agile Development method that can disseminate information as well as become a medium for renting art products and services to the wider community in an easily accessible manner. The results of the implementation of this system show increased efficiency in data management, more effective delivery of information to users or customers, and optimization of promotions through digital media. With this website-based information system, the Kirana Budaya Art Studio can improve the quality of services and support efforts to preserve arts and culture in a more professional and modern manner.
