Abstract

Stunting remains a significant national health issue in Indonesia, prompting the government to focus on its prevention through regular monitoring of child growth. This study aimed to determine the preferred IoT-based anthropometric measuring device for toddlers using Decision Support System (DSS) methods, specifically Analytic Hierarchy Process (AHP), Weighted Product (WP), and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). Two products, Product A and Product B, were evaluated based on criteria including accuracy, ease of use, durability, connectivity, and cost. The AHP method was used to determine the criteria weights, followed by the application of WP and TOPSIS to rank the products. The results indicated that Product A was consistently preferred, demonstrating superior performance in accuracy testing with an average accuracy of 98.76% for height and 99.21% for weight measurements, compared to Product B’s 95.42% and 96.85%, respectively. These findings validate the effectiveness of the DSS methods used, providing a reliable approach for selecting IoT-based healthcare devices. This study offers a practical decision-making framework for Posyandu and other healthcare facilities to ensure accurate and efficient child growth monitoring.

Abstract

This research analyses the efficiency of pre-and-post-merger Bank Syariah Indonesia (BSI). This research used a descriptive quantitative analysis method. The population in this research is Islamic banks, which were merged into BSI. The sampling technique was carried out using saturated samples, resulting in the merged of three Islamic Banks, namely Bank Syariah Mandiri (BSM), Bank Negara Indonesia Syariah (BNIS), Bank Rakyat Indonesia Syariah (BRIS), to become BSI. The data used is secondary data in the form of quarterly financial reports for 2019-2022. The research focused on input variables such as total fixed assets, third-party funds, operating costs, and financing. The data analysis techniques used to measure the efficiency of Islamic banks are the Econometric Model (Single Equation Model), Stochastic Frontier Analysis (SFA), and Independent Sample t-test. The result showed that pre-merger, the total fixed asset, total third-party funds, and operating cost as the input variables of the three Islamic Banks were optimal for generating financing. Therefore, the total assets, total third-party funds, and operating costs produced a more optimal impact on the distribution of total financing. It is shown that BSI, both pre-and-post-merger, has generally been efficient in its operational activities. The results of this research complement the theory related to the efficiency level of Islamic banks in terms of the amount of financing as measured by fixed assets, total third-party funds, and operational costs. Practically, the results of this research can be a reference for banks, especially Islamic banks, that will carry out mergers to measure their efficiency level.

Abstract

This study examines the strategic role of green banking in creating competitive advantage within the banking sector from a strategic management perspective. Using a quantitative approach, this research employs Structural Equation Modeling with Partial Least Squares (SEM–PLS) to analyze data collected from 210 managerial-level employees of commercial banks operating in Indonesia. The findings indicate that green banking has a positive and significant effect on competitive advantage, both directly and indirectly through strategic efficiency as a partial mediating variable. This result suggests that green banking contributes to competitive advantage not merely through regulatory compliance or reputational signaling, but through its integration into core strategic and operational processes. Strategic efficiency, reflected in process optimization, long-term cost reduction, and sustainable innovation, strengthens the effectiveness of green banking in generating superior competitive outcomes. These findings position green banking as a strategic capability that enhances organizational competitiveness when embedded within long-term strategic orientation. This study contributes to the strategic management and sustainability literature by providing empirical evidence from an emerging economy context and by clarifying the internal mechanisms through which green banking creates value. The results offer important implications for banking management in designing sustainability-driven strategies that support long-term competitive advantage
