Abstract

This study aims to compare two main theories in modern cosmology, namely the Big Bang Theory and the Steady State Theory, using a descriptive cosmographic approach. This study is motivated by the lack of deep understanding as well as the limited Indonesian literature discussing the fundamental differences between the two theories. By employing a qualitative method through literature review, this research examines the characteristics, advantages, and limitations of each theory based on the latest scientific evidence and cosmographic perspectives. The analysis results show that the Big Bang Theory has strong support from observational evidence, such as cosmic microwave background radiation (CMB), galaxy redshift, and the distribution of light elements, which reinforces the narrative of the expansion and evolution of the universe. In contrast, the Steady State Theory is considered less relevant due to the absence of observational evidence for the creation of new matter and its inability to explain structure and the dynamics of the universe that are currently observed.

Abstract

Studi Mikrogravitasdilakukan di Bukit Tambun, Tambun, Ipoh untuk mengidentifikasi struktur geologi bawah permukaan, terutama keberadaan rongga dan batas batuan. Sebanyak 121 titik pengukuran gravitasi dikumpulkan dan diolah untuk menghasilkan peta anomali Bouguer. Data kemudian dianalisis menggunakan beberapa teknik geofisika, termasuk Low Pass Filter (LPF), High Pass Filter (HPF), Total Horizontal Derivative (THD), dan 3D Euler Deconvolution. Peta anomali Bouguer menunjukkan anomali rendah di bagian tenggara dan barat yang mengindikasikan zona sedimen tebal, sedangkan anomali tinggi di utara menunjukkan keberadaan batuan dasar, terutama batu kapur dan granit. Analisis THD memperlihatkan pola sesar dominan berarah tenggarabarat laut. 3D Euler Deconvolution mengidentifikasi tiga zona rongga potensial pada kedalaman 12 hingga 43 meter serta struktur sesar pada kedalaman 4 hingga 39 meter. Pemodelan bawah permukaan melalui profil 2D menunjukkan keberadaan tiga lapisan utama: aluvium, batu kapur, dan granit, dengan batas yang hampir vertikal. Zona anomali rendah berbentuk bulat hingga semi-sferis dalam model ditafsirkan sebagai rongga atau zona depresi yang terisi sedimen, yang kemungkinan menunjukkan perkembangan sinkhole. Temuan ini memberikan kontribusi terhadap pemahaman potensi bahaya geologi dan kerangka struktur geologi wilayah studi.

Abstract

This study aims to examine the potential and challenges of utilizing Solar Power Plants (PLTS) in Medan City, which is geographically located near the equator and receives high exposure to sunlight throughout the year. The method used is a literature review with a narrative review approach that analyzes secondary data from various journals and relevant scientific articles. The results of the study show that Medan City has an average annual horizontal global solar radiation intensity of 463.61 W/m², with the potential for electrical power that can be generated from rooftop solar panels reaching 748.57 MW (monocrystalline), 598.85 MW (polycrystalline), and 299.43 MW (thin film). This potential is comparable to the capacity of large-scale power plants. The use of PLTS contributes to reducing carbon emissions, increasing energy security, creating jobs, and developing the local economy. However, challenges such as high installation costs, limited suitability of roof structures, and low public awareness are still major obstacles in the implementation of this technology. Therefore, synergy is needed between government policies, public education, and technological innovation to optimize the use of solar energy in urban areas such as Medan.

Abstract

Understanding of the Earth's rotation is often limited to the alternation of day and night. However, its impact is far more complex, including the formation of time zones and varying climate patterns. The objectives of this study include analyzing the Earth's rotation's influence on the formation of time differences between regions based on longitude and the relationship between the Earth's rotation and climate variations caused by atmospheric movement and global wind patterns. This study employs literature review techniques using secondary data, which involves collecting data indirectly by studying the relevant objects. The use of secondary data related to Earth's rotational movement influences time and climate is based on findings from previous research. The findings of this study reveal that the Earth's rotation causes the alternation of day and night and time differences in each region, with each 15-degree difference in longitude resulting in a one-hour time difference. In terms of climate, the Earth's rotation produces the Coriolis force, which deflects the direction of wind and ocean currents, thereby forming atmospheric circulation patterns such as the Hadley, Ferrel, and polar cells. These circulation patterns determine temperature and precipitation distribution across various regions, so the Earth's rotation directly shapes the distinct global climate characteristics of each area

Abstract

Space debris is increasingly becoming a global problem that has the potential to threaten the sustainability of space exploration and satellite operations. This study aims to evaluate the effectiveness of international policies and regulations that have been implemented in handling space debris, and toidentify gaps and challenges in their implementation. The research method used is a literature study, with an analysis of policy documents from international organizations, academic journals, and reports from related research institutions. Data analysis was carried out using the Miles and Huberman approach, including data reduction, data presentation, and drawing conclusions. The results of the study indicate that although there are a number of international agreements, such as the Outer Space Treaty 1967, the Liability Convention 1972, and the Registration Convention 1975, there is no effective law enforcement mechanism in cleaning up space debris globally. The lack of binding regulations and coordination between countries in mitigating space debris are major challenges that must be overcome. This study recommends the establishment of clearer international standards and an effective implementation system to ensure the sustainability of space exploration.
