Abstract

Abstract – Global climate change increases the frequency of extreme weather, impacting various sectors, including aviation. Accurate weather prediction becomes crucial to ensure the safety of human activities, including aviation operations. This study aims to predict air temperature variables on Runway 10 at Juanda Airport using a Long Short Term Memory (LSTM) architecture stacked with a Gated Recurrent Unit (GRU) architecture, named Hybrid LSTM. The data used in this study is air temperature (per minute) obtained from the Automatic Weather Observing System (AWOS) in (.csv) format. Testing was conducted for short-term predictions and comparisons were made between Hybrid and non-Hybrid models. The test results show that the LSTM-GRU architecture produced the lowest evaluation values for predicting temperature with an MSE of 0.0181, MAE of 0.0814, RMSE of 0.1345, and MAPE of 0.29% using a batch size of 64 and 20 epochs. This indicates that the developed model is suitable for predicting the next short-term period (5 minutes). For future research, model development is needed by adding features or adjusting hyperparameters to accurately predict the long term.Keywords: Predict, Air Temperature, Automatic Weather Observing System (AWOS), LSTM, GRU

Abstract

Abstract – Aviation safety and security are heavily influenced by airport visibility, as pilots require clear visual references for landing. However, poor weather conditions can reduce visibility and increase the risk of accidents. Therefore, an automated system is needed to classify visibility levels quickly and accurately, even when faced with the challenge of imbalanced datasets. This study employs a Generative Adversarial Network (GAN) approach, focusing on Vanilla GAN, DCGAN, and StyleGAN models. The data used is sourced from CCTV AWOS at Runway 10 of Juanda Airport, encompassing 14,458 images from the period of August 13 to 31, 2023. The models are evaluated using SSIM scores and feature extraction of color, texture, and HOG at various epochs. The results indicate that the Vanilla GAN model at 60 epochs is the most suitable for the minority class compared to the other models, based on feature evaluation, SSIM scores, synthetic image quality, and loss pattern outcomes. Its simple architecture aids in capturing low variation in the dataset, making it superior to more complex architectures like DCGAN and StyleGAN. Further optimization and architectural adjustments could enhance the results, especially for datasets with low variation like the one used in this study.Keywords: Aviation, GAN, Dataset

Abstract

The 110VDC batteries at the 150kV South Surabaya Substation have a shortage in the number of units. Therefore, they require extra supervision to ensure that protection and control equipment relying on DC power sources can operate normally during rectifier system outages, preventing potentially severe disruptions at the substation. The objective of this study is to use Matlab's forecasting degradation method for battery performance using Regression Learner, aimed at facilitating operators at the 150kV South Surabaya Substation. The research focuses on forecasting battery performance degradation using Gaussian Process Regression (GPR) with datasets obtained from observed discharging and charging tests compiled in Excel format. Data analysis techniques involve building a GPR model using Matlab software and comparing forecasted results with discharging test data over two years from PT. PLN (Persero). The study concludes that a 71% battery efficiency qualifies as sufficiently reliable backup power during AC or rectifier disruptions. This ensures continuous operation of protection and control equipment during blackouts, thereby preventing operational disruptions and serious safety issues.

Abstract

The increasing demand for electricity in Indonesia highlights transformers' crucial role in the electrical system. This study utilizes GRU (Gated Recurrent Unit) and LSTM (Long Short-Term Memory) in a deep learning framework to predict aging losses of transformer unit 5 at the 150 kV Waru Substation. The aim is to enhance grid reliability, and efficiency, and prevent disruptions like power outages. Conducted at the 150 kV Waru Substation, the research focuses on transformer loading and temperature data. Data preprocessing involves normalizing load, oil temperature, and winding temperature data. The model architecture combines GRU and LSTM to capture short-term and long-term patterns in time series data. Training employs the Adam optimizer with customized learning rates, and performance evaluation uses metrics such as MSE, RMSE, MAPE, and MAE. Results indicate the GRU-LSTM model trained with a batch size of 64 and 75 epochs achieves superior performance: MSE of 0.0000129008474202634, RMSE of 0.00359177496793207, MAPE of 0.3943965%, and MAE of 0.00000832911556912471. This model forecasts transformer 5's aging loss over the next 30 days with an average daily deterioration rate of 0.001378178 pu/day, peaking at 0.0030481415 pu. Keywords: Aging Loss Prediction, GRU, LSTM, Transformer
