Abstract

This research aims to determine the value of the Earth's gravitational acceleration (g) using the mathematical pendulum swing method with an unweighted linear regression approach, weighted linear regression, and the 4th-order Runge-Kutta numerical method. The data used are the results of measuring the swing period of the pendulum for various lengths of string. The analysis was carried out by calculating the average value of gravitational acceleration using multiple methods. The results show that weighted linear regression provides more consistent and accurate estimates than unweighted linear regression, with a high coefficient of determination (R²) value. The Runge-Kutta numerical method is also used to predict swing periods with a more in-depth mathematical approach, producing values ​​supporting experimental data trends. Overall, this research makes an average value of gravitational acceleration of around 9.11 m/s², close to the expected theoretical value. These findings show that the mathematical pendulum swing method can be used effectively to measure the Earth's gravitational acceleration with sufficient accuracy and provide an essential contribution in the context of physics education regarding the application of basic principles in physics experiments.

Abstract

Mount Lewotobi Laki-Laki since December 2023, the eruption status has increased, with a substantial increase in November 2024. This led to modifications in the distribution of temperature, the patterns of volcanic material flow, and the morphology of the land. The objective of this research was to examine the relationship between the elevation profiles and temperature fluctuations that occurred during the eruption of Mount Lewotobi Laki-Laki. This investigation illustrates the considerable impact of volcanic activity on the environment by employing satellite data-based methodologies, digital elevation models (DEMs), and thermal analysis. The results suggest that volcanic activity has a significant impact on the distribution of temperature and the alteration of geological structures. The observed temperature increase, which extends from the crater to the slopes and lowlands, has an impact on local ecosystems and atmospheric conditions. The precipitous elevation profile significantly impacts the flow pattern of volcanic material, such as lava and lahars, which can pose a disaster risk to settlements and community activities in the vicinity. This research underscores the necessity of ongoing monitoring for risk mitigation and community preparedness in volcanic disasters.

Abstract

Orang tua memiliki peran penting sebagai pendidik pertama dan utama dalam membentuk karakter anak. Pendidikan karakter tidak hanya menjadi tanggung jawab sekolah, tetapi juga berawal dari keluarga sebagai lingkungan terdekat anak. Penelitian ini bertujuan untuk menggambarkan peran orang tua di Desa Niopanda dalam menanamkan nilai-nilai moral, sosial, dan budaya kepada anak sejak usia dini. Metode yang digunakan adalah deskriptif kualitatif dengan pengumpulan data melalui observasi, wawancara, dan dokumentasi. Hasil penelitian menunjukkan bahwa orang tua di Desa Niopanda berperan melalui keteladanan, pengasuhan penuh kasih sayang, penanaman nilai budaya lokal, serta bimbingan spiritual. Namun, tantangan yang dihadapi adalah pengaruh teknologi, kesibukan orang tua dalam bekerja, serta berkurangnya peran tradisi lokal akibat modernisasi. Oleh karena itu, peran aktif orang tua perlu ditingkatkan agar generasi muda di Desa Niopanda tumbuh dengan karakter yang baik, berakhlak mulia, dan tetap menjunjung tinggi nilai budaya lokal.
