Abstract

Tides is caused by the gravitational forces of celestial bodies such as the sun and moon, lead to fluctuations in sea level on Earth. This study analyzes the frequency and height of tides measured by the Maumere tidal station (Stasiun pasang Surut Maumere) from January 12 to 14, 2023, comparing observed changes with theoretical predictions. The Fast Fourier Transformation (FFT) method, implemented via Microsoft Excel, was employed to dissect the tidal signal into its frequency components. Results indicate that the Maumere sea exhibits a diurnal tide cycle with an average height of 1.57 m during the observation period. The observed maximum tidal height change was 0.76 m, while the theoretical prediction, based on the Earth-moon distance of 0.37 million km on January 14, was 0.6 m. The root mean square error (RMSE) between observed and predicted tidal heights was 0.34 cm. This analysis demonstrates that FFT can effectively characterize tidal frequencies and contributes to the understanding of tidal behaviors, enhancing predictive models in oceanography.

Abstract

The simulation of the drift method application using a celestial body tracker has been done. Experiments were carried out by recording the movement of a celestial body tracker with variation orientation of polar angle and azimuth from the true south and polar angle a particular location. The variation is between -2° to +2°. It was found that the greater the difference in the mounting orientation from the true orientation, the greater the shift in altitude and azimuth of the celestial object’s path.

Abstract

Parabolic motion is the typical phenomenon in classical mechanics. The students are able to understand the concept by reading the data in the parabolic function. However, there is limited material for visual impaired students to study the parabolic motion data. One of the solutions to overcome this problem is the parabolic motion experiment development using sonification method. Research has been carried out to analyze the accuracy of the frequency produced by the speakers in data conversion assisted by Arduino Uno. The research also analyzes the effect of elevation angle variations on the resulting frequency changes. The data collection process is carried out by analyzing the percentage of accuracy using the average technique of the data recorded by the Phyphox application. The data analysis of the Phyphox application is compared with the data obtained from the Tracker application. From the results of data analysis obtained the percentage value of the velocity for the angle 30o, 45o, and 70o were 99.92%, 99.67%, and 98.42%, respectively. Therefore, it can be said that the preliminary sonification study is feasible to be used in physics experiments on parabolic motion learning, especially for visual impaired students. The final plotting result of this research shows that the frequency versus time at each angle produces a graph in the parabolic form. While the effect of angle variations on frequency changes is that the larger the angle, the slower it will reach the peak frequency.

Abstract

The pendulum is a classic oscillatory system commonly used in physics to study motion and damping phenomena. One notable damping mechanism is electromagnetic damping caused by eddy current induction. This study investigates the effects of varying the number of aluminium plate layers attached to the pendulum and the electric current supplied to a surrounding coil, which generates a magnetic field, on the pendulum damping time. An experimental approach was used by measuring the damping time across different combinations of plate layers and current levels. The data were analyzed to identify the relationship between these variables and the damping behavior of the pendulum. Results indicate a negative exponential relationship between the electric current and damping time, as well as a significant effect of aluminium plate layers on damping  efficiency. Increasing the number of aluminium plate layers enhances eddy current induction, resulting in stronger damping forces.

Abstract

This study aims to improve the accuracy of resonance analysis in closed pipe resonance through the measurement of quality factor (Q) and effective air column length. The method employed involves an automated system based on Arduino, equipped with an HC-SR04 sensor to measure distance and a KY-037 sensor to detect sound amplitude, integrated with Python-based data analysis for determining the resonance frequency. The measurement results show that the use of effective length with tube radius correction and improved frequency determination methods can reduce error from 1.33% to 0.24%, as well as decrease the standard deviation from 0.45 cm to 0.37 cm. Furthermore, quality factor analysis indicates an increase in the average value from 20 to 31, suggesting that the implemented resonance system and analysis method provide more accurate results, despite increased variability. Overall, the system successfully delivers more precise measurements in the analysis of resonance characteristics in closed organ pipes, particularly in relation to energy dissipation.

Abstract

This study aims to analyze sky brightness dynamics during a hybrid solar eclipse using the Sky Quality Meter (SQM). Strategic observation sites were selected along the eclipse path, and continuous data collection was conducted using the SQM-LU-DL, telescopes, weather stations, and GPS for accurate location and atmospheric data. Measurements began several days before the eclipse and continued throughout and after the event. Data collected included sky brightness, visual documentation, and atmospheric conditions, which were analyzed using GnuPlot to detect trends and patterns in brightness changes. The study revealed significant fluctuations in temperature and light frequency, with a sharp decrease at the eclipse's peak, followed by a return to normal levels. These findings emphasize the eclipse's impact on natural light intensity and highlight the importance of addressing light pollution. The study contributes to understanding astronomical phenomena's effects on the environment and human health, aiding in the development of effective light pollution mitigation strategies.

Abstract

In the digital age, hoaxes or false information are a significant challenge, as they can harm public comprehension, form inaccurate opinions, and endanger the health and safety of individuals. Artificial intelligence technology, particularly large language models (LLMs) like Llama 3, provides an innovative solution to these challenges. A sophisticated generative model with superior natural language processing capabilities, Llama 3 enables the effective detection and clarification of hoaxes. A dataset that is seven times larger than its antecedent, Llama 2, is utilized to train this model. The dataset has a token capacity of up to 128K and a context length of up to 8 K. By utilizing these capabilities, Llama 3 is capable of comprehending context, offering responses that are grounded in scientific data, and reducing response errors. Educational chatbots, interactive web platforms, and mobile applications that are based on Llama 3 can be implemented. This model effectively identifies and clarifies false information regarding cosmic rays that are purportedly hazardous through the presentation of pertinent scientific facts, as demonstrated by case studies. Llama 3's capabilities encompass its capacity to modify parameters to generate valid and pertinent responses. This renders it a critical instrument for bolstering community resilience to the dissemination of falsehoods, as well as digital literacy and awareness. Llama 3, which is open source, facilitates global collaboration in the development of a more secure and trustworthy information ecosystem.
