Coral Reef Diversity and Habitat Characteristics in the Waters of Nasi Island, Aceh Province, Indonesia
Bibliographic record
Abstract
As benthic marine organisms within the class Anthozoa (Phylum Cnidaria), corals form the foundational structure of coral reef ecosystems.These ecosystems are vital marine habitats, supporting diverse aquatic species.This study aims to analyze the coral diversity index and habitat characteristics in the waters of Nasi Island, Aceh Province.The research was conducted in July and August 2024.The survey was conducted across three distinct research sites.Using a purposive sampling method, thirty coral samples were collected from a 2 × 2-meter plot at each location.The Shannon-Wiener diversity index was used to analyze the diversity of coral species.The research identified 32 coral species belonging to 6 families.The diversity index analysis indicated that the coral diversity index ranged from 2.26 to 2.97, falling into the moderate category.Among the study locations, Pasie Janeung had the highest coral diversity, while the lowest diversity was observed at Dedap.In the Dedap and Alue Rieung areas, the decline of coral reef ecosystems is linked to community activities, particularly the use of boats and fishing vessels for fishing and docking.This highlights the urgent need for intensified conservation efforts, such as establishing no-anchoring zones, to ensure the long-term sustainability of the coral reefs.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
