Abstract

Indonesia's distinct geographic and climatic features make forecasting the weather there tricky. Due to its location at the equator and between two enormous oceans, the nation endures erratic weather patterns. Despite technical developments, the Meteorology, Climatology, and Geophysics Agency (BMKG) require assistance with precise forecasting. This research seeks to increase prediction accuracy using the Long Short-Term Memory (LSTM) algorithm, a deep learning technique appropriate for time series data processing. The research focuses on cloud data sets to improve the prediction of heavy rain. The potential of LSTM in weather forecasting has been demonstrated in earlier research, focusing on identifying rain at particular intervals. This research compares daily and weekly heavy rain prediction models using Python.  Results reveal that the weekly model outperforms the daily model, achieving 85% accuracy compared to 80%. These findings highlight the effectiveness of LSTM in addressing the limitations of existing methods, offering a foundation for more reliable weather forecasting tailored to Indonesia’s conditions.

Abstract

Solar energy is an abundant and environmentally friendly renewable energy source; therefore, its utilization through solar cell technology is highly relevant in addressing energy challenges in the Industrial Era 4.0. However, many Vocational High School (SMK) students still lack a deep understanding of the working principles and applications of this technology. The activity of socializing and implementing solar cell prototypes at SMK Voctech 1 Tangerang aims to enhance students' understanding of the concept, benefits, and operation of solar cells, as well as provide direct practical experience in installing and operating simple solar power systems. This activity involves delivering theoretical material on solar energy, types of solar cells, and implementing a 360 WP solar cell prototype that can be used to charge electronic devices, serving as a simulation of alternative energy sources. The results of the activity showed that students were able to conceptually and technically understand solar cell technology and were able to install and operate the prototype well. Thus, this activity is expected to be the first step in fostering students' awareness and skills in utilizing renewable energy independently and sustainably.
