Abstract

Satellite navigation has become an integral part of the global infrastructure for a variety of applications, from transportation navigation to earth observation and national security. Satellite navigation systems have become an important part of modern life. This system is used for various purposes, such as vehicle navigation, asset tracking, and communication. Each system has different working mechanisms and procedures. This research aims to identify the working procedures of various satellite navigation systems in the world. The research method used is a qualitative descriptive method through literature study sourced from journals, scientific articles, books and other relevant sources. The results of this research show that satellite navigation systems, such as GPS, use radio signals to determine location on the earth's surface. GPS consists of three main parts, namely control, space, and user. GPS satellites send signals that are used to determine position, speed, direction, and time. GPS has wide-ranging uses, including in ship navigation, object tracking, and management of agricultural to military supply chains.

Abstract

Indonesia rawan mengalami bencana hidrometereologi, salah satunya banjir. Kota Payakumbuh secara geografis berada pada daerah Pegunungan Bukit Barisan yang berjarak 124 km dari Kota Padang. Penelitian ini bertujuan untuk mengetahui dan memetakan tingkat rawan banjir di Kota Payakumbuh berbasis Sistem Informasi Geografis melalui software ArcGIS 10.4.1. Metode yang digunakan adalah skoring dan pembobotan terhadap parameter hujan yang kemudian di-overlay. Data penelitian berupa data sekunder yang diambil melalui berbagai sumber, diantaranya Geoportal Kota Payakumbuh, dan DEMNAS. Hasil yang diperoleh berupa peta rawan banjir dengan Kecamatan Payakumbuh Utara dan Kecamatan Payakumbuh Timur sebagai kecamatan dengan tingkat kerawanan banjir tertinggi. Faktor utama penyebab terjadinya banjir di Kota Payakumbuh adalah sedikit adanya lahan terbuka/tanah kosong sehingga rendahnya daya resap air hujan. Hal ini diperparah dengan intensitasnya curah hujan tahunan yang sangat tinggi pada musim penghujan yaitu mencapai kisaran >3000 mm/tahun. Kata Kunci: banjir, rawan bencana, Kota Payakumbuh, Sistem informasi Geografis

Abstract

Generation Z demonstrates a high level of concern for environmental issues, yet their pro-environmental behavior remains inconsistent. SMA Negeri 1 Medan is recognized as a leading school with adequate facilities, though the level of environmental awareness and behavior among its students is not yet well understood. The use of the AQAL quadrant in analyzing these aspects remains limited, even though this approach can offer a comprehensive analysis across internal and external, as well as individual and collective dimensions. This research aims to analyze the environmental awareness and pro-environmental behavior of students at SMA Negeri 1 Medan. A mixed-methods approach with a sequential explanatory strategy was employed, involving 72 students from grades X and XI. Data were collected through questionnaires, interviews, and observations, then analyzed using the AQAL quadrant approach to integrate quantitative and qualitative findings. The students demonstrated a very high level of environmental awareness (level 5), while their pro-environmental behavior was at a moderate level (level 3), often driven by instructions or competitive activities. The school culture reached a good level (level 4), and the school’s policies strongly supported sustainability (level 5), although consistent implementation by all members of the school community still needs improvement. This indicates that high environmental knowledge, a sustainability-oriented culture, and supportive school policies have not yet significantly translated into consistent pro-environmental behavior among students.

Abstract

Rapid changes in the world of work due to globalization and the information technology revolution require an evaluation of the competencies needed considering the gap between educational outcomes and job market demands. Outcome-Based Education (OBE) is considered to be able to bridge this gap by focusing on learning outcomes that are relevant and in accordance with the needs of the world of work, replacing the teacher-centered teaching method that is still dominant. This study aims to analyze the implementation of OBE in the Department of Geography Education and evaluate the level of student learning achievement to meet professional demands in the field of geography. This research uses a quantitative descriptive method to describe the level of student learning achievement related to implementing Outcome-Based Education (OBE) in the Department of Geography Education, with a population of all students and samples taken using purposive sampling from the 2023 and 2024 classes. Data were collected through a closed questionnaire distributed via Google Forms, using a Likert scale from 1 to 5, and analyzed using descriptive statistics to calculate the percentage of respondents' answers and the average answer per item. The study's results showed that implementing Outcome Based Education (OBE) had a positive impact with an average student learning achievement reaching 73.8%. However, there are still shortcomings in mastery of technology and application of theory to real practice, which emphasizes the need to develop a more applicable curriculum. To improve these skills, it is recommended that universities integrate experiential learning methods such as internships and case studies and focus on curriculum evaluation that is integrated with practical experience.

Abstract

Indonesia is one of the countries with the largest Muslim population in the world that has great potential to develop halal tourism. The purpose of this study is to analyze the development of halal tourism in Sabang City based on the potential, cultural and religious influence in Sabang City, the suitability and availability of tourist facilities in meeting the needs of Muslim tourists, as well as the promotion and marketing system of halal tourism in Sabang City in the domestic and international markets. The research method used in this study is qualitative research using descriptive analysis. The results of the study show that Sabang City has the potential for natural, nautical, religious, heritage, culinary, tourist villages, and artificial tourism for the development of halal tourism that respects Islamic values. Aceh's culture, which is thick with Islamic religious values, affects the development of halal tourism in Sabang City by ensuring that all aspects of tourism are in accordance with Islamic law including dress rules on the beach, halal food, and the availability of places of worship in tourist destinations. The existence of facilities that suit the needs of Muslim tourists, such as tourist attractions, halal-certified inns and restaurants, Islamic banking services, worship facilities and transportation facilities that comply with sharia principles further strengthens the attractiveness of Sabang City as a halal tourist destination. Promotional activities carried out by tour managers increase the acceptance, purchase, and loyalty of tourism products through international promotions such as Sail Sabang and Sabang Marine Festival, as well as domestic promotions with government support, social media marketing, and cooperation with travel.
