Abstract

Indonesia with its predominantly Muslim population, has great potential in developing the Islamic capital market to support the country's economy. This is indicated by the development of Islamic capital market instruments every year. In addition, macroeconomic aspects also affect the stability of the economy in a country. Therefore, this study was conducted to examine the influence between the Islamic capital market and macroeconomics on economic growth in Indonesia in the period 2014–2023. The data used are secondary data from various sources regarding the Islamic capital market, macroeconomics, and national economic growth. This research utilizes quantitative methods with descriptive analysis in the form of line diagrams and inference in the form of Vector Error Correction Model. The results showed that Islamic stocks have a causal relationship with economic growth. In the short-term model, Islamic capital market and macroeconomic variables have no significant influence on economic growth. However, Islamic stocks, Islamic bonds, Islamic mutual funds, exchange rates, and exports have a significant positive effect on economic growth in the long-term model. Meanwhile, inflation and imports have no significant effect on economic growth. The VECM model estimation results produced an R-Squared value of 79.63%.

Abstract

Stunting is a serious health problem that impacts the quality of life of children under five. In 2023, East Nusa Tenggara recorded the second highest prevalence of stunting in Indonesia, influenced by health, socio-economic and environmental factors. In terms of the environment, remote sensing technology can be utilised to monitor environmental factors that contribute to stunting, such as vegetation conditions, access to clean water, and soil conditions. This study aims to evaluate the incidence of stunting among children under five using a hybrid machine learning approach, combining predictive modeling and cluster analysis.

In terms of the environment, remote sensing technology can be utilised to monitor environmental factors that contribute to stunting, such as vegetation conditions, access to clean water, and soil conditions. This study aims to evaluate the incidence of stunting among children under five using a hybrid machine learning approach, combining predictive modeling and cluster analysis. The results indicate that eXtreme Gradient Boosting Regressor (XGBR) is the best model for estimating stunting prevalence, with a Root Mean Squared Error (RMSE) of 3.2076 and an value of 0.7223. Meanwhile, for clustering results, K-Means Clustering is identified as the most effective method for grouping districts/cities based on socioeconomic and environmental factors. The clustering process produced two groups, such as vulnerable (Cluster 1) and highly vulnerable (Cluster 2), with connectivity, Dunn Index, and silhouette coefficient values of 29.290, 0.6931, and 0.4509, respectively. These findings are expected to serve as a basis for policymakers in formulating targeted interventions to reduce stunting rates, particularly in highly vulnerable areas. at eXtreme Gradient Boosting Regressor (XGBR) is the best model for estimating stunting prevalence, with a Root Mean Squared Error (RMSE) of 3.2076 and an value of 0.7223.
