Abstract

The clustering, one of statistical analysis, can be used for understanding population patterns and as a basis for more targeted policy making. In this ecological study, we explored the population dynamics across 23 districts/cities in Aceh Province. The study used the Aceh Population Development Profile Year 2022 data, focusing on the total population, in-migrants, out-migrants, fertility, and maternal mortality as variables. The study employed descriptive statistics to ascertain the data distribution, followed by the Shapiro-Wilk test to evaluate normality, which is crucial for selecting the appropriate statistical methods. The Spearman test was used to determine correlations between the total population and the variable as indicators. Probabilistic Fuzzy C-Means (PFCM) method is used for clustering. To optimize clustering, the silhouette coefficient was calculated using the Euclidean Distance and the elbow method, with the results analyzed using R-4.3.2 software. This study's design and methods aim to provide a nuanced understanding of demographic patterns for targeted policy-making and regional development in Aceh, Indonesia. Based on the data normality test results, only fertility (p-value = 0.45), while the other variables are not normally distributed. Spearman test was used, and the results showed that only in-migrants (p-value = 1.78 x 10-6) and out-migrants (p-value = 2.30 x 10-6) correlated to the Aceh Province population. Using the population variable and the two variables associated with it, it was found that 4 is the best optimum number of clusters, where clusters 1, 2, 3, and 4 consist of three districts/city, nine districts/city, four districts/city and seven districts/city respectively.

Abstract

Maternal Mortality Rate (MMR) in Indonesia has experienced a concerning annual increase, reaching 4,627 deaths in 2020 compared to 4,221 in 2019. This upward trajectory underscores the urgency of investigating the factors contributing to MMR. Recognizing the spatial heterogeneity and outliers in the data, our study employs the Robust Geographically Weighted Regression (RGWR) method with the Least Absolute Deviation approach. Using secondary data from the 2020 Indonesian Health Profile publication, the research seeks to establish province-specific models for MMR in 2020 and identify the key influencing factors in each region. Standard regression analyses fall short in addressing the complexities present in the data, making the RGWR approach crucial for understanding the nuanced relationships. The chosen RGWR model utilizes the Least Absolute Deviation method and a fixed kernel exponential weighting function. Notably, this model maintains a consistent bandwidth value across all locations, showcasing its robustness. In evaluating the model variations, the exponential fixed kernel weighting function emerges as the most optimal, boasting the smallest Akaike Information Criterion (AIC) value of 23.990 and the highest coefficient of determination  value of 93.66%. The outcomes of this research yield 24 distinct models, each tailored to the unique characteristics of every province in Indonesia. This nuanced, location-specific approach is vital for developing effective interventions and policies to address the persistently high MMR. By providing insights into the complex interplay of factors influencing maternal mortality in different regions, the study contributes to the groundwork for targeted and impactful public health initiatives across Indonesia.

Abstract

Recent discourse in mathematics education emphasizes the need for culturally relevant pedagogy and the integration of higher-order thinking skills, yet limited research explores the intersection of ethnomathematics and computational thinking within school curricula. This study addresses this gap by proposing a novel instructional framework that incorporates computational thinking into the ethnomathematical exploration of Rumoh Aceh—a traditional Acehnese house—within the context of junior high school geometry education in Indonesia. The research aims to enhance students’ understanding of geometric concepts such as lines, angles, shapes, and spatial structures through culturally grounded learning experiences. Using the four core components of computational thinking—decomposition, abstraction, pattern recognition, and algorithmic thinking—the geometric design of Rumoh Aceh is analyzed to reveal its mathematical significance. Data collection was conducted through ethnographic methods, including observation, interviews with local experts, and documentation analysis. The findings demonstrate that applying computational thinking to cultural artifacts fosters students’ ability to recognize geometric patterns, simplify complex problems, and develop structured problem-solving strategies. Furthermore, the integration of cultural context enriches students’ appreciation of their heritage while cultivating critical thinking and mathematical reasoning. This study provides empirical evidence supporting the pedagogical value of merging ethnomathematics with computational thinking, offering a meaningful and culturally responsive approach to mathematics education.
