Abstract

The aim of this research was to use the Fast Fourier Transform (FFT) to analyze the frequency of notes produced by the traditional Te'dek flute of the Toraja people in South Sulawesi, Indonesia. The purpose of the study was to contribute to the preservation of the Toraja's cultural history by providing an evaluation of the Te'dek flute's tonal characteristics. The research process included recording the sound of the flute, applying the FFT to the recorded data to extract frequency values, and analyzing these values to determine the frequency of each note within an octave. What sets the Te'dek flute apart is its unique tuning process, where the maker skillfully adjusts the fingerholes' diameter using hand tools and relies on intuition to determine the sound without any external measurement. The results of the study showed that the FFT can be used to accurately determine the frequency of the Te'dek flute and that the strength of airflow in the flute's cavity plays a significant role in determining the frequency of the tone.

Abstract

The increase in cloud cover is an important indicator in predicting upcoming weather. However, manual observations of cloud cover are still limited and time-consuming. Therefore, this research aims to develop a cloud cover classification model based on measurement data in Lolai using the Naive Bayes machine learning method. In this study, data on cloud cover, temperature, and humidity measurements were collected directly in Lolai for 30 days and using online BMKG data. Then, the data was processed and divided into training and testing datasets. The Naive Bayes model was applied to the training data and its accuracy was tested on the testing data. The research results show that the cloud cover classification model based on Naive Bayes has varying accuracy levels depending on the data source. For direct measurement data, the model achieved an accuracy rate of 63%, while for online BMKG data, the model achieved an accuracy rate of 80%. In testing on the testing data, the model successfully classified cloud cover based on temperature and humidity data. This research contributes to identifying the relationship between temperature, humidity, and cloud conditions and evaluates the performance of the Naive Bayes model in determining the influence of air temperature and humidity on cloud conditions. It is expected that this research can serve as a basis for the development of weather prediction systems in the future.

Abstract

This study aims to improve the accuracy of current measurements in solar power systems using the ACS712 sensor and linear regression modeling. While the ACS712 sensor is commonly used for current measurement in solar systems, it often faces accuracy issues. In this research, we measured current using the ACS712 sensor alongside a validated reference device and applied a linear regression model to correct any inaccuracies. The results show that our linear regression model significantly boosts the accuracy of ACS712 sensor current measurements. We also conducted performance tests with the model on the Arduino Uno platform, which revealed increased measurement accuracy in various testing scenarios. Before implementing the model, the average difference between ACS712 sensor measurements and reference device readings was 0.364. After implementing the model, this difference dropped substantially to just 0.044.
