Abstract

Saham adalah instrumen investasi dengan harga yang sangat fluktuatif. Harga saham dalam kurun waktu tertentu membentuk suatu data runtun waktu. Saat ini, salah satu metode yang cukup populer untuk menangani data runtun adalah Recurrent Neural Network (RNN). Tulisan ini membahas penerapan RNN di masa yang akan datang dalam memprediksi harga saham berdasarkan data harga saham beberapa tahun ke belakang. Tetapi RNN standar memiliki kelemahan yaitu terjadinya kondisi vanishing gradient. Oleh karena itu, arsitektur Long Short Term Memory (LSTM) digunakan pada RNN untuk mengatasi masalah tersebut. Sebagai pembanding, ditampilkan pula hasil prediksi dengan menggunakan model RNN standar. Hasilnya, RNN dengan arsitektur LSTM dapat dengan baik memprediksi harga saham dibandingkan RNN standar yang direfleksikan oleh nilai Mean Absolute Error (MAE) antar kedua model.

Abstract

The cooling system is one of the essential components in motor vehicles that requires proper maintenance. Disruption in the performance of the cooling system can lead to an increase in the engine's operating temperature. Ultimately, an overheated engine can cause reduced performance, damage to engine components, and even systemic component failure in motor vehicles. The purpose of this community service activity is to enhance the knowledge of Public Infrastructure and Facilities Handling (PPSU) officers in maintaining the cooling systems of their operational vehicles, which are three-wheeled motorcycles. To achieve this goal, we conducted a workshop at the RW.016 Secretariat, West Cengkareng, West Jakarta. As a result of this activity, PPSU officers in the area have increased their understanding of what needs to be done regularly to ensure the optimal performance of their operational vehicles' cooling systems. An optimally performing cooling system allows the operational vehicles to function properly, ultimately leading to maximum performance by the PPSU officers.
