Abstract

This study aims to analyze the use of documentary video-based learning media to increase student learning motivation in history in grade XI TKJ SMKN 1 Banawa. The background of this study is based on the low motivation of students in learning history when only using conventional methods, so a more engaging, contextual, and appropriate media is needed for students' characteristics. This study used a qualitative approach with descriptive methods. Data were collected through observation, interviews, and documentation over seven meetings, then analyzed through data reduction, data presentation, and conclusion drawing. The results showed that the use of documentary video can increase student learning motivation. This was evident in increased student enthusiasm during learning, active participation in discussions, courage to ask questions, and willingness to summarize the video content. Teachers also stated that students became more focused, understood historical events more easily, and did not get bored easily. Challenges encountered included limited technical facilities such as projectors and speakers, limited personal devices for re-watching videos, and some students' unfamiliarity with learning through audiovisual media.

Abstract

Challenges in Implementing the Merdeka Curriculum in History Learning at SMA Negeri 1 Sarudu. Skripsi. Bachelor’s degree. History Education Study Program, Social Science Education Department, Teacher Training, and Education Faculty, Tadulako University. Under the supervision of Fajar Nugroho. This research aims to describe the implementation process, identify the challenges encountered, and examine the solutions applied in applying the Merdeka Curriculum in history learning at SMA Negeri 1 Sarudu. This research used a descriptive qualitative approach with data collection techniques through observation, interviews, and documentation. Data analysis was conducted using the Miles and Huberman model, which includes stages of data reduction, data presentation, and conclusion. The research results show that implementing the Merdeka Curriculum at SMA Negeri 1 Sarudu encompasses three stages: planning, implementation, and evaluation, centred on students' needs and characteristics. In the process, various problems were found, including student objections to P5 projects, teachers' difficulties in implementing differentiated learning, facility limitations, teachers' lack of initial understanding, and constraints in assessment time management. The solutions implemented by the school and teachers include socialising the benefits of P5, student mentoring, learning style mapping, teacher training, facility optimisation, and more structured assessment scheduling. This research concludes that implementing the Merdeka Curriculum at SMA Negeri 1 Sarudu still faces challenges, but these can be overcome through collaboration between the school and teachers so that history learning runs more effectively and in line with the principles of independent learning.

Abstract

Padang City, as one of the cities the largest on the west coast of Sumatra Island, plays a strategic role in the economy and government. One of the vital infrastructures that supports public activities is the street lighting system. However, the monitoring and maintenance of streetlights still face obstacles, especially in North Padang District, which is the busiest area due to the presence of numerous educational facilities, government offices, and economic centers. This research aims to develop a WebGIS application that facilitates the monitoring and management of street lighting more efficiently. Our research contributes by introducing a new approach to spatial-based streetlight management strategies. This approach is based on a methodology for field data collection and spatial database development to manage all stages of streetlight infrastructure management. This application integrates geospatial technology by utilizing GeoServer, QGIS, and PostgreSQL for visualization and spatial data management. With this system, information about the location and condition of streetlights can be accessed in real-time, thereby facilitating better planning and maintenance of street lighting infrastructure. The result of this study is a WebGIS application capable of mapping and monitoring streetlight points interactively. The implementation of this system is expected to assist relevant authorities in improving the effectiveness of street lighting management in Padang City and contribute to the development of geospatial technology-based solutions for urban infrastructure.
