Mathematics is one of the main skills taught from elementary school to college, playing a role in developing critical and logical thinking patterns of students. However, many elementary school students have difficulty understanding mathematical concepts, especially spatial figures, due to the lack of supporting learning media. This study aims to explore the effectiveness of using Trimatra (three-dimensional) media in mathematics learning in elementary schools. Trimatra media, such as three-dimensional models of spatial figures, allows students to visualize and understand the characteristics and relationships between spatial figures in a concrete manner. The results of the literature study show that Trimatra media not only increases students' knowledge of mathematical concepts, but also motivates students to be actively involved in learning, increases critical thinking skills, and overall learning outcomes.

This article aims to analyze Semarang's city diplomacy in solving environmental problems. Cities have an increasingly large role to play in this globalization era due to complex global issues, especially environmental issues. Cities are also having difficulty dealing with globalization due to the speed of population growth, economic pressures, excessive land use, and the increasing use of motor vehicles that release pollutants into the air. To address these issues, cities around the world are doing their best to find cooperative solutions through diplomacy. In addition, many national capitals cannot handle multiple tasks and, therefore, need to delegate some of their burden to other cities. In line with these objectives, this study utilizes an exploratory and descriptive qualitative research method, focusing on Semarang's diplomacy efforts. This study found that the Semarang city government has been perceived as an institution with clear political objectives that is fully committed to the practice of city diplomacy to engage directly, albeit in a limited way, in multilateral and bilateral international cooperation to find solutions to its environmental problems. The city government is no longer seen as an object of implementation of program plans formulated at the central level but also has the opportunity to formulate strategic plans or bottom-up procedures based on the needs of local communities and the suitability of the model with environmentally sustainable urban development.

This study examines the implementation of policies for the recognition and protection of the indigenous law community in Kampung Kuta, Ciamis Regency. A qualitative approach was employed, gathering data through in-depth interviews, observations, and document analysis. Thematic analysis identified key issues, and triangulation ensured validity by cross-referencing multiple data sources. A central finding is the ongoing conflict between customary laws in Kampung Kuta, which support communal land ownership, and national land regulations that emphasize individual land registration, leading to legal ambiguity and disputes. The study reveals substantial challenges, including inadequate socialization by the government, which has resulted in limited awareness within the indigenous community regarding their rights. Furthermore, limited financial and human resources impede effective implementation, while bureaucratic inefficiencies and poor coordination among implementing agencies have delayed policy outcomes. To address these issues, it is essential to improve resource allocation, conduct regular community workshops to enhance understanding of indigenous rights, and establish a legal framework that harmonizes customary and national laws. Strengthening local authorities and aligning policy objectives with the cultural context of Kampung Kuta are also critical steps. These measures are necessary to safeguard indigenous rights and preserve Kampung Kuta’s cultural heritage, fostering a sustainable model for indigenous rights protection in Indonesia.
