<![CDATA[Data processing in waste bank management systems faces substantial challenges when extracting structured information from unstructured textual data containing transaction records, customer information, and waste categorization details. This study develops and validates an automated Named Entity Recognition (NER) system based on the IndoBERT transformer architecture to process textual records from Makassar waste bank operations. The approach fine-tunes the indolem/indobert-base-uncased model through domain-specific adaptation targeting waste management vocabulary and operational terminology. The dataset comprises 975 textual records collected from 8 Waste Bank Units in Makassar City. These records were systematically annotated using the BIO tagging scheme for eight entity types: B-LOCATION, B-PERSON, B-WASTE_CATEGORY, B-WASTE_TYPE, I-PERSON, I-WASTE_CATEGORY, I-WASTE_TYPE, and O. The dataset was partitioned into training (682 samples, 69.9%), validation (146 samples, 15.0%), and test sets (147 samples, 15.1%) using stratified sampling methodology with high inter-annotator agreement (κ=0.91). Experimental results show outstanding performance with 94.37% test accuracy, 90.65% precision, 94.37% recall, and 92.21% F1-score, outperforming general-purpose Indonesian NER approaches. Perfect performance was achieved for waste type recognition (B-WASTE_TYPE: 100% F1-score) and location identification (B-LOCATION: 100% F1-score), while waste category classification reached 96% F1-score. This implementation successfully automates entity extraction from Makassar waste bank textual data, reducing manual processing time by 95% while maintaining high accuracy levels. This research makes important contributions to Indonesian environmental natural language processing. These contributions include transformer adaptation methodologies for resource-constrained domains, validated IndoBERT performance on Indonesian waste bank data, the first Indonesian waste management NER dataset, and demonstrated feasibility of NLP-based environmental policy systems.]]>
