Abstract

AbstrakProses terjadinya Gerhana Bulan Total merupakan fenomena astronomi yang  terjadi ketika seluruh permukaan Bulan tertutupi oleh bayang bayang Bumi atau disebut dengan umbra. Hal ini dapat terjadi ketika konfigurasi antara Bulan, Bumi, dan Matahari berada pada satu garis lurus. Oleh karena itu, fenomena Gerhana Bulan Total akan terjadi bersamaan dengan fase Bulan Purnama. Tujuan dilakukannya pengabdian ini adalah untuk mengamati Gerhana Bulan. Metode yang digunakan adalah observasi dan pengisian angket skala Danjon. Pelaksanaan kegiatan dilakukan pada tanggal 8 November 2022 yang dimulai pada pukul 18.00 WITA dengan peserta yang berasal dari masyarakat umum dan masyarakat Universitas Muhammadiyah Maumere. Berdasarkan hasil implementasi diketahui bahwa kondisi cuaca pada saat pelaksanaan sulit dilakukan pengamatan karena kondisi mendung disertai gerimis. Namun, peserta yang mengamati dapat menilai kecerahan gerhana bulan Kata kunci: gerhana bulan total; astronomi; skala danjon; pengamatan. AbstractThe total lunar eclipse process is an astronomical phenomenon that occurs when the Earth's shadow, called the umbra, covers the entire moon's surface. It can happen when the configuration between the Moon, Earth, and Sun is straight. Therefore, the total lunar eclipse phenomenon will co-occur with the complete moon phase. The purpose of doing this service is to observe the Lunar Eclipse. The method used is observation and filling out the Danjon scale questionnaire. The implementation was carried out on November 8, 2022, starting at 18.00 WITA with participants from the general public and the Universitas Muhammadiyah Maumere community. Based on the implementation results, it is known that the weather conditions at the time of observation were challenging because of cloudy conditions accompanied by drizzle. However, participants can judge the brightness of the lunar eclipse. Keywords: total lunar eclipse; astronomy; danjon scale; observation.

Abstract

The efficacy of NuminaMath 7B, an AI model that was created to address mathematical challenges, is assessed in this investigation. We evaluated the model's accuracy and efficiency against conventional methods through experiments that produced quantitative data. Qualitative data were collected through surveys and interviews with users to gain insight into their experiences and pinpoint areas for improvement. The survey results indicated that users found NuminaMath 7B to be pertinent, effective, and user-friendly, as evidenced by the exceptionally high average scores in user experience (95), perception of features and interface (90), and additional feedback (85). NuminaMath 7B was able to offer mathematical solutions with logical and detailed explanations as a result of the model's development through two phases of adjustments, which were conducted using the Chain of Thought (CoT) methodology and inspiration from the Tool-Integrated Reasoning Agent (ToRA) framework. Testing demonstrated that the model achieved a score of 29 out of 50 in the AI Math Olympiad competition, despite encountering difficulties in resolving more intricate problems. This study underscores the significance and urgency of AI technology, particularly in the field of mathematics, as well as the significant potential of AI models to facilitate a more comprehensive comprehension of mathematical concepts.

Abstract

In November 2024, the eruption of Mount Lewotobi Laki-laki on Flores Island, Indonesia, resulted in the release of substantial volcanic aerosols, including sulfur dioxide (SO₂) and volcanic debris. These aerosols impacted the environment, health, and aviation activities. The objective of this investigation is to examine the temporal and spatial dynamics of volcanic aerosols by employing the Absorbing Aerosol Index (AAI) in conjunction with TROPOMI satellite data (Sentinel-5P). The methodologies employed are as follows: spatial-temporal analysis with Google Earth Engine (GEE), aerosol dispersion simulation with the HYSPLIT model, and data processing with the Sentinel Application Platform (SNAP). The results indicated a substantial increase in volcanic activity from November 8th to 11th, 2024, as evidenced by an ash column that reached a height of as much as 10,945 m. The distribution of aerosols was influenced by atmospheric dynamics, with high concentrations observed in the vicinity of Mount Lewotobi Laki-laki and extending to the east-southeast. Although the level of volcanic activity declined in late November, aerosol concentrations were still detected in the atmosphere. This investigation offers critical insights into the distribution of volcanic aerosols during the eruption and its effects on disaster risk mitigation and air quality. It is anticipated that these discoveries will facilitate the implementation of more sustainable and effective risk management strategies for volcanic eruptions.
