Abstract

Background: Stunting remains a major public health challenge in Indonesia, with a 21.5% prevalence in 2023, impacting children’s development and the nation’s human capital. This study aims to provide additional findings on nutritional status of Indonesia under five children in Cianjur and Klaten.Methods: This study conducts a secondary data analysis of survey data among healthy under five children of blue collar workers in 2 areas (Cianjur and Klaten) in Indonesia with a cross-sectional design and combines with existing nutrition status in Indonesia. Various statistical analysis methods were performed accordingly to obtain insights in refining and scaling up stunting prevention strategies. Results: Overall, 236 under five children of blue collar workers were enrolled in this study. We observed that Cianjur has higher under nutritional status overall than Klaten. The Cianjur region have higher underweight status (10.8%), higher stunting status (20.4%), and higher wasting status (4.3%) compared to Klaten (7.7%, 16.8%, and 2.1%, respectively). In comparison with the prevalences of under nutrition coming from latest national survey, Cianjur found to be has lower underweight status (7.0%), lower stunting status (11.4%) and lower wasting status (3.4%) than Klaten (18.6%, 24.5%, and 7.5%, respectively). There is no significant difference stunting proportion between the two areas. Findings from this survey may reflect the impact of initiatives done by local government in reducing the impact of undernutrition (including stunting) among blue collar workers’ children. Conclusion: This study highlights the positive impact of Indonesia’s stunting prevention programs. Further research is needed to strengthen evidence and refine strategies for better child nutrition and health.

Abstract

The primary problem in using conventional red bricks as wall materials lies in their low construction efficiency, high dependence on mortar, and inconsistent structural quality, which makes them less suitable for modern construction demands that require speed, accuracy, and sustainability. These limitations create a strong need for innovative building materials capable of improving mechanical performance while enhancing construction efficiency. This study aims to analyze the influence of interlocking geometry variations in concrete bricks, specifically the Keylock Brick and Multi Gridlock types, on compressive strength, and to compare their performance with conventional red bricks to determine the most structurally optimal design. The research employs a quantitative experimental approach, where specimens are produced based on the predetermined geometric designs. Compressive strength tests are conducted using a Compression Testing Machine (CTM) to measure the maximum applied load. Data analysis is performed descriptively and comparatively based on the surface area and compressive strength values obtained from each sample. The results indicate that interlocking geometry significantly affects compressive strength performance. The Keylock Brick type achieves an average compressive strength of 100.03 kg/cm², classified as a solid concrete brick of quality level I according to SNI 03-0349-1989. Meanwhile, the Multi Gridlock type records an average compressive strength of 60.48 kg/cm², categorized as a hollow concrete brick of quality level II. Both values are higher than that of conventional red bricks, which average 31.68 kg/cm². These findings demonstrate that optimizing interlocking geometry can substantially enhance the structural performance of concrete bricks, offering a more efficient and sustainable alternative for modular construction applications
