Abstract

In the era of globalization, rapid technological advancements have significantly impacted the financial sector, particularly stock price movements. This study aims to contribute to financial analysis and investment by providing a predictive tool to help investors make more informed investment decisions. The Random Forest method, a machine learning al-gorithm known for effectively handling complex and heterogeneous data, is used to pre-dict stock price movements. The study utilizes historical stock data from companies listed on the Indonesia Stock Exchange (IDX) as a case study. The resulting predictive model demonstrates high accuracy, achieving 98% accuracy, with an R-squared (R²) value of 0.94 and a Mean Absolute Percentage Error (MAPE) of 0.40%. This research identifies key factors, such as Previous, High, Low, Volume, and Change, that significantly influ-ence stock price movements. The strengths of this study lie in its use of an extensive da-taset, involving 104 stock codes as examples, and its integration of interactive visualiza-tion via Streamlit to enhance data interpretation. This tool is expected to be a reliable solu-tion that provides superior predictive capabilities compared to traditional methods and supports more accurate investment analysis in the stock market.

Abstract

Advances in information and communication technology have encouraged the transformation from manual systems to digital-based systems, including in stock management. This research aims to develop a website-based stock management information system using the Reorder Point (ROP) and Economic Order Quantity (EOQ) methods for Panglong Siagian Bersaudara. ROP is used to determine reorder time, while EOQ calculates the optimal number of items that must be ordered to minimize total costs. The system was designed using the Rapid Application Development (RAD) method, resulting in a fast and structured design. The implementation results show that the system is able to increase stock management efficiency by reducing the risk of shortages or excess items, optimizing storage costs, and supporting real-time data-based decision making. With the integration of ROP and EOQ, this system provides a comprehensive solution for stock management at Panglong Siagian Bersaudara.

Abstract

In doing business, sales are something that is expected to increase sales because this is a determining factor in whether a business is running smoothhly. The more the sales value of a product increases, the more profit will be obtained. The use of forecasting methods such as Exponential Smoothing can forecast by applying the average value over time for the future. This research has 2 stages of the first method, namely using the Reserch And Development and waterfall methods, the Reserch And Development method technique of collecting data is to make observations, interviews directly and externally, while the waterfall method is one of the structured methods of each development step, the waterfall model is an application development cycle that follows steps that sequentially combine projects from start to finish. This research resulted in a monitoring system where every month the store does not experience any shortage or excess of stock.Keywords: Exponential Smoothing; Forecasting; Period; Monitoring AbstrakDalam menjalankan bisnis, penjualan merupakan suatu hal yang diharapkan dapat meningkatkan penjualan karena hal ini merupakan faktor penentu lancar tidaknya suatu bisnis. Semakin meningkat nilai penjualan suatu produk sehingga profit yang didapati akan lebih banyak. Penggunaan metode peramalan seperti Exponential Smoothing dapat meramalkan dengan mengambil rerata nilai sebagian periode sebelumnya untuk periode kedepanya. Penelitian ini memiliki 2 tahapan yaitu menggunakan metode Reserch and Development dan waterfall. Metode Reserch and Development merupakahn teknik penghimpunan data secara melaksanakan wawancara serta observasi langsung maupun eksternal, sedangkan metode waterfall merupakan salah satu metode terstruktur setiap langkah pengembangannya, model waterfall merupakan suatu siklus pengembangan aplikasi yang mengikuti tahapan yang menggabungkan proyek secara berurutan dari awal sampai akhir. Penelitian ini menghasilkan sebuah sistem monitoring dimana setiap bulannya toko tidak mengalami stok kurang ataupun lebih.Kata kunci: Exponential Smoothing; Peramalan; Periode; Monitoring
