Abstract

The research aims to determine the nutritional content in the leaves and rhizomes of Enhalus acoroides from Badak Badak Island, Bontang City. The analysis of nutritional content uses proximate test analysis in the form of ash, fat, protein and carbohydrate content. The distribution characteristics of water quality and basic substrate based on stations used the Principal Component Analysis approach. The substrate texture at Stations AU and BT is clayey sand, while Station CB is sandy loam. The ash content in the rhizomes is lower than in the leaves with a ratio of 1:1.36. The lipid content in rhizomes is lower than in leaves with a ratio of 1:1.23. The protein content in rhizomes is lower than in leaves with a ratio of 1:1.23. The carbohydrate content in leaves is lower than in rhizomes with a ratio of 1:1.17.

Abstract

Seagrass beds provide habitat for the abundance and diversity of megagastropods that form the food chain in supporting the productivity of coastal waters. The purpose of this study was to determine the diversity and abundance of megagastropoda in the seagrass beds of Tihi-Tihi Village. This study was conducted in October 2024 - February 2025 using a purposive sampling method. Megagastropoda sampling using Van Veen Grab and seagrass stands using 50x50cm square frames. Data analysis included abundance, community structure index and morphometrics of individual megagastropoda, and seagrass stand density and Pearson Product Moment correlation analysis. The results of the study found 18 species of megagastropoda. Diversity in moderate criteria, moderate population uniformity and dominance in moderate criteria with an abundance of individuals reaching 567 individuals/m2. The seagrass found 4 species of seagrass, namely E. acoroides, T. hemprichii, C. rotundata, and H. ovalis. There is a positive and very close correlation between the abundance of megagastropoda and the characteristics of seagrass density.
