Abstract

This study aims to evaluate the PT TIMAH Tbk sea reclamation program, specifically the artificial reef program. The research was conducted from March to July 2024 at the artificial reef module sinking locations for the Obligatory Years of 2019, 2021, and 2023. The fish data collection method used a modification of the Belt Transect. The biomass calculation method was modified by adding several fish families that are economically valuable target fish. The location of the 2021 Obligatory Year artificial reef modules had the highest number of fish species (40 species), the highest H' value (3.20), and the heaviest biomass (2,908.80 kg/ha). The range of diversity values at all locations was between 1.80-3.20, falling under the criteria of "moderate" and "high." The range of dominance index values was between 0.06-0.36, falling under the "moderate" criteria. The range of evenness values was between 0.34-0.53, falling under the "moderate" and "low" criteria. The range of fish biomass values was between 129.66-2,908.80 kg/ha. The longer the artificial reef modules were submerged, the more schooling fish species increased, while target fish species decreased due to fishing activities. The criteria for the value analysis results refer to the criteria used for natural habitat calculations (coral reefs). Researchers recommend specific value criteria for artificial habitats in disturbed environmental conditions (offshore mining activities).

Abstract

Background: Airway management is critical in pediatric anesthesia, as failure can lead to severe complications, including cardiac arrest. Anticipating and preparing for difficult intubation is essential, particularly in children with unique anatomical and physiological characteristics. The Colorado Pediatric Airway Score (COPUR) is a predictive tool for assessing intubation difficulty in pediatric patients.Objective: This study evaluates the validity of COPUR in predicting difficult intubation in children.Methods: A cross-sectional diagnostic study was conducted on 121 pediatric patients (aged 1–8 years) undergoing general anesthesia at Cipto Mangunkusumo Hospital. COPUR assesses jaw structure, mouth opening, prior intubation history, uvula visibility, neck movement, and additional modifying factors (macroglossia, obesity, mucopolysaccharidosis, and protruding teeth). A COPUR score >7 was used to predict difficult intubation, while intubation difficulty was defined by an Intubation Difficulty Score (IDS) >5.Results: A COPUR score ≥8 predicted difficult intubation in 15.7% of patients, whereas actual difficult intubation occurred in 9.92%. A COPUR threshold of ≥7 provided optimal sensitivity (83.3%) and specificity (61.47%), outperforming the original cutoff of 8 (50% sensitivity, 87% specificity). The score demonstrated good discriminative ability (AUC-ROC: 0.770, 95% CI: 0.685–0.842) and suitable calibration (Hosmer-Lemeshow test, p = 0.584).Conclusion: The COPUR score is a valid tool for predicting difficult intubation in pediatric patients aged 1–8 years, demonstrating fairly good discrimination and calibration values.
