Ethnomathematics as a study bridges mathematics with local cultural contexts, including traditional architecture. Istana Maimun, a cultural heritage of the Malay people, holds a wealth of geometric elements that reflect local wisdom and cultural values. This research aims to explore the geometric aspects of Istana Maimun's architectural design through an ethnomathematical approach. The study identifies patterns of symmetry, proportions, and geometric functions applied in architectural elements such as ornaments, spatial layouts, and building structures. The analysis reveals that the geometry in Istana Maimun's architecture not only serves an aesthetic purpose but also carries philosophical meanings closely tied to Malay cultural identity. This research is expected to contribute to the development of ethnomathematics studies and the preservation of local wisdom.

Improving the quality of Human Resources (HR) is a major challenge in facing global competition. Education as the main means of improving the quality of HR in Indonesia is still faced with the problem of inequality of access and quality between regions. This inequality causes disparities in educational development between urban and remote areas. This study focuses on grouping provinces in Indonesia based on aspects of educational development in 2023, using cluster analysis. Secondary data from the Central Statistics Agency (BPS) is used as the basis for analysis, including variables of average length of schooling, Gross Participation Rate (APK), Pure Participation Rate (APM), number of senior high schools, and community literacy development index. This study uses hierarchical and non-hierarchical cluster analysis methods to group provinces in Indonesia. The results of the hierarchical cluster analysis using the average linkage method show the most optimal cluster with the formation of three clusters. The first cluster consists of 31 provinces, the second cluster consists of 2 provinces, and the third cluster consists of 1 province. Data characteristics show large variations in the number of senior high schools and relative homogeneity in the average length of schooling between provinces.

This study aims to determine the development of MSME financial performance as seen from the optimization of village fund management and financial literacy of MSME actors in Kubu Additional Village. The population is all MSME actors who have received assistance in the form of funds from the village and the number of samples in this study is 41 MSME actors. The data analysis technique used in this study is the Structural Equation Modeling-SEM based on SEM variance, which is famously called Partial Least Square (PLS) visual version 3.0. The results of this study suggest that financial management does not have a significant effect on financial performance in MSMEs. Financial literacy does not moderate the influence of financial management on financial performance in this study.

Reduced appetite, diarrhea, cough, and joint pain are common health issues. Traditional medicinal plants such as Temu Ireng, Curcuma, Sand Ginger, and Ginger have been used to treat these conditions. This study aims to optimize the formulation of lozenges containing these plants using a combination of mannitol and sucrose as excipients through the SLD (Simple Lattice Design) method. Five formulations with varying ratios of mannitol and sucrose (FI = 75:25, FII = 25:75, FIII = 100:0, FIV = 0:100, FV = 50:50) were prepared using wet granulation. Granule physical properties were evaluated, and the optimum formulation was identified using statistical analysis including normality tests and one-sample t-tests. The results indicated that FI (mannitol 75%, sucrose 25%) provided the most desirable characteristics, with excellent granule flow, compressibility, and uniformity in lozenge quality. This research contributes to the development of herbal lozenges with optimized excipient combinations, enhancing the efficacy and quality of traditional medicine products.

Public Green Open Space (RTH) is an essential element in urban spatial planning to support environmental sustainability. Through the process of photosynthesis, RTH helps absorb carbon dioxide (CO?) produced by human activities, such as transportation and industry, thus contributing to climate change mitigation. This study aims to explore the role of RTH in absorbing CO? and the challenges faced in its management. The study was conducted using a systematic approach through literature analysis and case studies in several cities in Indonesia and around the world. The research results indicate that vegetation type, area size, and environmental conditions are the main factors affecting the carbon absorption capacity of RTH. Large trees have a significantly higher capacity to absorb CO? compared to shrubs and grass, with the ability to absorb up to 250.63 tons of CO? per year per tree. However, challenges such as limited RTH area, urbanization pressure, and lack of public awareness remain obstacles to optimal RTH management. The recommendations of this study include increasing the area and quality of RTH through data-based strategies, community participation in management, and the development of policies that support sustainability. With proper management, RTH can function as a climate change mitigation tool while improving the quality of life for urban communities.
 

The This study aims to explore the implementation of online learning of Teaching Skills and Microteaching courses, focusing on three main aspects: preparation, implementation, and evaluation of learning. This study also considers the challenges that arise due to student involvement in the Merdeka Belajar Kampus Merdeka (MBKM) program, which often affects the consistency of their participation in regular learning. This study was conducted using a qualitative descriptive method with a case study design. The results showed that online learning was quite effective in conveying teaching skills theory through digital materials and asynchronous activities. However, teaching practice simulations faced several limitations, such as the difficulty of observing non-verbal elements, classroom management, and spontaneous responses of students during online simulations. Technical constraints, especially unstable internet connections, were also major obstacles in implementing learning. In addition, students involved in MBKM reported difficulties in dividing time between program assignments and regular course preparation, which impacted their participation and engagement.
