Abstract

This study aims to analyze the clustering of districts/cities in East Nusa Tenggara Province (NTT) using the Fuzzy Geographically Weighted Clustering method optimized through the Flower Pollination Algorithm (FGWC-FPA). The data consist of eight health and sanitation indicators for 2024. The analysis produced two clusters with distinct characteristics. Cluster 1 is dominated by areas with relatively higher rates of complementary feeding and good BCG immunization coverage but still shows a higher proportion of low birth weight (LBW) infants and limited access to drinking water and sanitation. Meanwhile, Cluster 2 demonstrates significant advantages in access to proper drinking water (90.37%) and proper sanitation (83.19%), as well as more optimal Hepatitis B immunization coverage. Evaluation of cluster validity using Classification Entropy (CE) and the Separation Index (SI) shows that the best configuration is obtained at m = 1.5 with c = 2, yielding the lowest CE value (0.584872) and reasonably good cluster separation (SI = 1.069092). Thus, the FGWC-FPA method is capable of producing optimal cluster partitioning and can serve as a basis for formulating more targeted health intervention strategies in NTT.

Abstract

Understanding spatial disparities in human development is essential for designing equitable development policies. This study examines the spatial variation of the Human Development Index (HDI) in East Java Province using an integrated Geographically Weighted Regression–Flower Pollination Algorithm (GWR--FPA) optimized with a Tricube kernel. The integration of GWR and FPA enables simultaneous spatial weighting and metaheuristic-based bandwidth optimization. Three predictors were analyzed: population size ($X_1$), literacy rate ($X_2$), and mean years of schooling ($X_3$). Statistical diagnostics indicated significant spatial autocorrelation and heteroskedasticity in the OLS residuals, justifying the use of a spatial modeling framework. The GWR estimates revealed strong spatial non-stationarity: $X_1$ showed no significant local effect, whereas educational factors ($X_2$ and $X_3$) were significant in all 38 districts and cities. The FPA optimization enhanced bandwidth selection, resulting in improved model fit. Model comparison based on AIC and AICc showed that the GWR--FPA--Tricube model achieved the lowest values (AIC = 135.8821; AICc = 137.0045), outperforming both global OLS and standard GWR. These findings demonstrate that education-related variables are the primary drivers of HDI variation in East Java, while demographic size contributes minimally. The optimized model provides a more accurate spatial representation of local development disparities, supporting targeted policy interventions and illustrating the effectiveness of integrating metaheuristic optimization within spatial regression.

Abstract

Stunting is a problem that is affected by the socioeconomic and environmental conditions of the public. The present study evaluates the impact of the financial state, environmental quality, and child feeding practices on the nutritional and physical stunting using a Bayesian nonparametric truncated spline regression model. To do this, a single knot spline structure was used a capture non-linear affects and thresholds, posterior estimation being conductied with Gibb's sampling. The results exhibit that all of the three predictors have a significance after the knot point on the right arrives, indiacting to saturation affects. As for the economic standing and the environmental quality, their effect is consistent, while feeding practices hold a more considerable impact on the nutritional stunting. From model diagnostics, the model had a good fit and predictive accuracy. The results highlight the importance of feeding practices and economic improvement and environmental sanitation, and display the benefits of the Bayesian spline technique for handling complex data.

Abstract

Background: Diabetes mellitus is a chronic metabolic disorder characterized by elevated blood glucose levels due to insufficient insulin production or ineffective insulin utilization. Persistent hyperglycemia can lead to serious acute and chronic complications. One non-pharmacological approach to help reduce blood glucose levels is physical activity, such as foot exercises. Foot exercises are simple, easy to perform, do not require special equipment, and can be practiced independently by patients with type 2 diabetes mellitus. Objective: To determine the effect of foot exercise intervention on blood glucose levels in a type 2 diabetes mellitus patient with the nursing problem of blood glucose imbalance in the internal medicine ward of RSUD Blambangan Banyuwangi. Methods: This scientific paper is structured as a case study using the nursing care approach, which includes assessment, nursing diagnosis, planning, implementation, and evaluation. The non-pharmacological intervention consisted of foot exercises performed for three consecutive days, with blood glucose levels measured before and after the intervention. Result: After performing foot exercises for three consecutive days, the patient's blood glucose level decreased significantly from 316 mg/dL to 124 mg/dL. This result indicates that the foot exercise intervention had a positive effect on blood glucose stabilization. Conclusion: : Foot exercise is proven to be an effective, simple, and easily applicable non- pharmacological intervention to help reduce blood glucose levels in patients with type 2 diabetes mellitus. This intervention can serve as a supportive therapy in the management of hyperglycemia.

Abstract

Kemiskinan merupakan permasalahan pembangunan yang berkaitan erat dengan kualitas sumber daya manusia, khususnya pendidikan. Penelitian ini bertujuan untuk menganalisis pengaruh Angka Harapan Lama Sekolah (AHLS) laki-laki terhadap jumlah penduduk miskin di Indonesia. Penelitian ini menggunakan pendekatan kuantitatif dengan data sekunder runtun waktu (time series) periode 2014-2024 yang bersumber dari Badan Pusat Statistik (BPS). Populasi sekaligus sampel penelitian ini adalah seluruh data nasional AHLS laki-laki dan jumlah penduduk miskin selama periode pengamatan. Metode analisis yang digunakan adalah regresi linier sederhana dengan data yang ditransformasikan ke dalam logaritma natural dan diolah menggunakan perangkat lunak SPSS, didahului oleh uji asumsi klasik. Hasil penelitian menunjukkan bahwa AHLS berpengaruh negatif dan signifikan terhadap jumlah penduduk miskin dengan koefisien regresi sebesar -2,063 dan tingkat signifikansi 0,006. Nilai Adjusted R Square sebesar 0,546 menunjukkan bahwa 54,6 persen variasi jumlah penduduk miskin dapat dijelaskan oleh AHLS laki-laki. Temuan ini menunjukkan bahwa peningkatan pendidikan laki-laki berperan penting dalam upaya pengentasan kemiskinan melalui peningkatan kualitas sumber daya manusia di Indonesia.

Abstract

This study aims to analyze the influence of women’s per capita expenditure and women’s expected years of schooling on the number of poor people in Indonesia. The research uses a quantitative approach with secondary time-series data obtained from official publications of the Badan Pusat Statistik covering the period 2014–2024. The data were analyzed using multiple linear regression after conducting classical assumption tests to ensure the reliability of the model. The results show that women’s per capita expenditure has a negative influence on poverty, indicating that higher levels of women’s economic welfare tend to reduce the number of poor people. Meanwhile, women’s expected years of schooling show a positive but not significant relationship with poverty. Overall, both variables together contribute to explaining variations in poverty levels. These findings suggest that improving women’s economic conditions plays an important role in poverty reduction efforts. However, this study is limited by the relatively short observation period. Therefore, future research is recommended to expand the observation period and include additional variables to obtain more comprehensive results regarding the factors influencing poverty in Indonesia. Keywords: Women’s Per Capita Expenditure; Expected Years of Schooling; Poverty; Human Resource Development
