Abstract

Wildfires are increasingly recognized as major environmental hazards that endanger ecosystems, human health, and economic stability. In practice, various monitoring efforts, such as hotspot detection, burned-area indices, and field inspections still depend on reliable spatial information to quantify fire impacts over large regions. Accurate segmentation of burned areas from satellite imagery plays a vital role in supporting post-disaster response and sustainable land management. This paper proposes a novel framework for burned area segmentation using multispectral imagery sampled by Random Subspace Band Selection (RSBS) with a U-Net architecture with an ensemble encoder. The RSBS module generates multiple 3-band subsets from Landsat-8 data, incorporating spectrally informative bands such as Near-Infrared (NIR) or Shortwave Infrared (SWIR). These subsets are used to train U-Net models with an ensemble of encoder backbones ResNet34, ResNet50, DenseNet121, MobileNetV2 and InceptionV4 for spectral and architectural diversity. The final predictions are aggregated using majority voting to enhance robustness and generalization. The framework is evaluated on a publicly available Indonesian burned area dataset encompassing diverse land cover types. Experimental results demonstrate that the proposed ensemble model achieves up to 0.7673 IoU, 0.8734 mIoU, and 0.8683 F1 Score, outperforming the best single-backbone model. These findings confirm that the proposed framework offers a scalable, accurate, and adaptable solution for wildfire damage assessment using satellite data.

Abstract

Indonesia has substantial potential to become a global hub for the halal food industry due to its large Muslim population and increasing demand for halal products in both domestic and international markets. However, the potential of halal food industry clusters, particularly among micro, small, and medium enterprises (MSMEs), has not yet been fully optimized. This study aims to examine strategies for optimizing halal food industry clusters as a pillar of the Indonesian economy. A qualitative approach was employed using primary and secondary data collected through literature reviews and relevant online sources. The data were analyzed descriptively to identify key factors supporting halal industry development. The findings indicate that strengthening halal certification systems, expanding halal industrial zones, increasing halal literacy among MSMEs, enhancing government policy coordination, promoting domestic halal products, and developing international business networks are essential strategies for improving the competitiveness of halal food clusters. Community participation and collaboration among government institutions, industry actors, and consumers also play a crucial role in supporting sustainable halal industry development. The study concludes that an integrated cluster-based approach can strengthen MSME competitiveness, expand market access, and support Indonesia’s ambition to become a leading global halal industry hub while promoting long-term economic sustainability.
