Full text linkThe rapid advancement of information technology has significantly influenced business operations, particularly in data processing, sales transactions, and management reporting. However, many small and medium-sized enterprises (SMEs) in Indonesia, including Grosir Uncu Aris, still rely on manual systems that are prone to data redundancy, human error, and inefficiency in generating accurate sales reports. This study aims to design and implement a website-based sales information system using the Laravel framework to overcome these limitations. The system development employed the Waterfall model, consisting of sequential stages: requirement analysis, system design, implementation, testing, and evaluation. During the design phase, Unified Modeling Language (UML) diagrams were used to visualize system structure and workflow, while the MySQL database ensured data integrity and normalization. The implementation utilized the Model-View-Controller (MVC) architecture in Laravel to maintain modularity and scalability. The testing phase applied black-box and white-box methods to ensure all functional modules such as login authentication, product management, transaction processing, and sales reporting performed correctly. The results show that the system successfully automates business processes, significantly improves data accuracy, and enhances operational efficiency. All modules functioned according to user expectations with a 100% success rate in testing. Moreover, the integrated reporting module allows users to generate real-time, detailed transaction summaries, supporting better managerial decision-making. This research demonstrates that Laravel-based information systems can serve as an effective digitalization strategy for SMEs, offering flexibility, security, and ease of maintenance for long-term sustainability
Comparison of Stock Mutual Fund Price Forecasting Results Using ARIMA and Neural Network Autoregressive Model
Full text linkStock mutual funds gained popularity among the public as an investment alternative due to the convenience they offer, especially for beginner investors who have limited time and investment knowledge. Compared to money market and bond mutual funds, these mutual funds offer higher potential returns but also come with higher risks due to value fluctuations, so forecasting stock mutual fund prices is essential to minimize losses. Since stock mutual fund prices is time series data, this research employs two forecasting models such as Autoregressive Integrated Moving Average (ARIMA) and Neural Network Autoregressive (NNAR). The objective of this research is to determine the best-performing model between ARIMA and NNAR, and compare their forecasting accuracy using the Mean Absolute Percentage Error (MAPE). The data used consists of daily closing prices of stock mutual funds from March 1, 2022, to March 31, 2025, with the criteria that the selected issuers have been operating for more than five years. The results of this research show that the best ARIMA and NNAR for the RNCN are ARIMA([1],1,0) and NNAR(2,2); for TRAM are ARIMA(0,1,[1]) and NNAR(4,1); for SCHRP are ARIMA(0,1,[1]) and NNAR(4,2); for MICB are ARIMA([1],1,0) and NNAR(2,2); and for BNPP are ARIMA([1],1,0) and NNAR(5,1). The MAPE values in the same order are 6.83% and 5.49%; 6.53% and 5.75%; 8.57% and 7.10%; 8.39% and 8.75%; 8.51% and 7.30%. Based on the comparison, NNAR outperformed ARIMA in four out of five mutual funds, with lower MAPE values and also marked by the ARIMA model tend to produce stable or unchanging values over the long term. The results of this research are expected to assist investors in consederating by choosing NNAR model, both in the short and long term, to obtain better stock mutual fund price forecasts
