Abstract

Abstract This study aims to measure the accuracy in predicting time series data using the LSTM (Long Short-Term Memory) machine learning method, and determine the number of epochs needed to produce a small RMSE (Root Mean Square Error) value. The result of this research is a high level of variation in RMSE value to the number of epochs needed in the data processing. This variation is quite difficult to obtain the right epoch value. By doing an iteration of the LSTM process on the number of different epochs (visualized in the graph), then the number of epochs with a minimum RMSE value will be easier to obtain. From the research of BBRI's stock data prediction, a good RMSE value was obtained (RMSE = 227.470333244533). Keywords: long short-term memory, machine learning, epoch, root mean square error, mean square error. Abstrak Penelitian ini bertujuan untuk mengukur ketelitian dalam memprediksi data time series menggunakan metode mesin belajar LSTM (Long Short-Term Memory), serta menentukan banyaknya epoch yang diperlukan untuk menghasilkan nilai RMSE (Root Mean Square Error) yang kecil. Hasil dari penelitian ini adalah tingkat variasi yang tinggi nilai rmse terhdap jumlah epoch yang diperlukan dalam proses pengolahan data. Variasi ini cukup menyulitkan untuk memperoleh nilai epoch yang tepat. Dengan melakukan iterasi dari proses LSTM terhadap jumlah epoch yang berbeda (di visualisasikan dalam grafik), maka jumlah epoch dengan nilai RMSE minimal akan lebih mudah diperoleh. Dari penelitan prediksi data saham BBRI diperoleh nilai RMSE yang cukup baik yaitu 227,470333244533. Kata kunci: long short-term memory, machine learning, epoch, root mean square error, mean square error.

Abstract

The Office of Religious Affairs (KUA) is one of the work units of the Ministry of Religion which is tasked with fostering and providing services to the community at the sub-district level. The Pasar Minggu Subdistrict Religious Affairs Office as the government agency coordinates activities and carries out internal and cross-internal activities in the sub-district area. To that end, the Office of Religious Affairs carries out documentation of marriage statistics, builds mosques in its territory, monitors zakat, waqf, baitul maal and other social services, monitors population and develops sakinah family programs. In carrying out the registration of marriage, the KUA of Pasar Minggu Subdistrict still has shortcomings in the system for recording marriages that are carried out. The drawbacks include the manual marriage registration process, making it less effective and inefficient. The manual recording is still making marriage reports which are still recorded in the ledger, so if you want to find data, the staff will manually look for the report data. Seeing this obstacle, the authors have the idea to create a system that can process data easier and simple in use so as to save time and streamline the work of KUA staff. In this study, the authors used several stages of work, starting from the process of analysis, planning, design using the PHP programming language and MySQL database, to the implementation stage with an object-oriented approach using UML (Unified Modeling Language). The results obtained from a system that the author created can help KUA staff in inventorying marriage data, helping them also in making systemized marriage reports and in finding registrants and marriage reports to be given to the Head of the Office of Religious Affairs (KUA).
