Infant mortality remains a public health problem in Aceh Province, Indonesia. Health services during pregnancy are an essential factor in reducing infant mortality. Studies examining factors such as maternal and child health services that have implications for infant mortality in Aceh province are still scarce. Therefore, this study aims to examine the correlation between maternal and child health services variables such as Blood-Supplementing Tablets (TTD), Coverage of the First Visit of Pregnant Women (K1), Coverage of the First Visit of Pregnant Women (K4), and management of Obstetric Complications to live births and to map the maternal and child health services obtained during pregnancy. A cross-sectional study was used as the research study. This study used descriptive statistics, such as measures of data centering and data dispersion. In this work, inferential statistical analysis was conducted using the Shapiro-Wilk test, Spearman test, and fuzzy c-means. The result of the Shapiro Wilk test stated that the live birth rate variable and all Maternal and Child Healthcare Services variables were not normally distributed (p-value < 0.05), all Maternal and Child Healthcare Services variables were positively correlated to live birth rate based on the Spearman test (p-value < 0.05). Based on the Silhouette Index with 0.555, the formation of 3 clusters is the optimal cluster. The clustering is based on the Maternal and Child Healthcare Services that have been provided, where the first, second, and third clusters consist of five districts/city, eight districts/city, and ten districts/city, respectively, as a result of Fuzzy C-Means Clustering.

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.

Penelitian ini bertujuan untuk menganalisis pengaruh variasi produk dan promosi terhadap volume penjualan pada paket skincare di Toko Indah Store di Sukabumi. Metode analisis yang digunakan adalah kuantitatif dan metode yang digunakan yaitu uji regresi linier berganda, uji t, dan uji f, dengan menggunakan sampling Rao Purba hingga diperoleh sampel dalam penelitian ini berjumlah 100 responden yang dipilih secara acak. Hasil analisis menunjukkan bahwa promosi memiliki pengaruh yang signifikan terhadap volume penjualan dengan koefisien regresi promosi sebesar 0.267 dengan koefisien determinasi sebesar 60.4%, sedangkan koefisien regresi variasi produk sebesar 0.142 dengan koefisien determinasi sebesar 27.3%. Variasi Produk dan Promosi terhadap Volume Penjualan mempunyai persamaan regresi linier berganda Y=-1.754+0.012X1+0.257X2. Uji hipotesis diperoleh F hitung lebih besar dari F tabel (74.466>3.09). Dengan begitu ada pengaruh positif yang signifikan secara simultan antara variabel Variasi Produk dan Promosi terhadap Volume Penjualan.

The Scoop Light Fishing (SLF) gear is an innovative fishing technology capable of producing catches exceeding one ton per trip. Despite its high productivity and ability to operate during all lunar phases, including bright-moon periods, its construction and effective fishing time have not been scientifically assessed. The purpose of this study is to examine the construction of the SLF and identify its effective fishing period in the waters of Bero Village, Pulau Tiga, West Muna Regency. The research employed a survey method, with data collected through direct observation and interviews, and analyzed using qualitative and quantitative approaches. Quantitative analysis included a normality test and a one-way ANOVA at the 0.05 significance level, followed by an LSD post hoc test. The results show that the SLF consists of two main components: an elongated scoop-net bag directly connected to the fish hold and a square lighting system comprising four panels equipped with white and yellow lights, producing a total output of 4,765 watts. The SLF operates effectively during all lunar phases; however, fishing effectiveness is highest during the full moon phase (Q.III), as indicated by a significance value of less than 0.05. Keywords: Effectiveness; moon phases; scoop light fishing

This study aims to determine the crude fiber content in potato chip samples. Potato chips were chosen because they are a processed food product commonly eaten as a snack and are commonly consumed by the public. The crude fiber test is a method for determining the insoluble content of food samples, such as vegetables, tubers, or fruit. The method used in this study was quantitative with an experimental approach. The samples used were purple sweet potato chips, banana chips, and orange chips, each with different oven-drying methods. The drying time for chips was 1 hour. The results of this study indicate that purple sweet potato chips (4.462%-6.241%) have a relatively high crude fiber content, compared to the other two samples. The high fiber content in purple sweet potato may be due to its thicker fiber network compared to the other two samples. In addition, factors such as the maturity level of the tuber, growing conditions, and processing methods can affect the fiber content obtained. Based on these results, purple sweet potato is a healthy food that can be a healthy snack and can be used to increase fiber intake in the daily diet.
