Abstract

Seagrass beds are potential marine resources to be utilized, and ecologically, seagrass beds are some of the important functions of the coastal area. Many organisms are ecologically and biologically very dependent on the presence of seagrasses. The ecosystem is an important food source for the organism by many sea organisms that use it as a spawning place. This study aims to determine the diversity of fish in seagrass beds in Padaratan Beach, Sarudik Subdistrict, Central Tapanuli Regency. A gillnet is used to obtain fish samples at three observation stations during the period from mid-March to April 2018. Fish diversity can be agreed by looking at the composition of fish species and diversity index. The results of this study show the total number of fish obtained, 196 individuals, consisting of 12 families and 14 species. The highest number of fish catches is at Station II with a total catch of 70 individuals. The highest relative abundance of stations I, II, and III with values ​​of 22.96%, 20.01%, and 23.07% are found in fish species from the family Hemaramphidae with Zenarchopterus gilli species. The diversity index value (H') of all observation stations shows that species richness is in a moderate condition with values ​​of the station I (2,339), station II (2,439) and station III (2,367). While the uniformity value (e), shows the value of station I (0.866) station II (0.924) and station III (0.897) observations are in a stable condition (0.75 <e d ”1.00). Such conditions indicate that the distribution at each observation station is equitable.

Abstract

Mangroves are a unique ecology that resides in places with salinity, which are inundated at low tide when there is no flooding and at high tide. Mangrove forests that are increasingly damaged cause the quality and quantity to decrease. Using different species of fungi that can accelerate the growth of mangroves is one attempt to increase and get high-quality mangrove seeds. This study aims to shed light on the fungi that can dramatically improve the growth of Avicennia marina seedlings. Mangroves can absorb organic and non-organic materials produced by decomposing microorganisms, which come from leaf litter or other decomposed materials. In this experiment, several fungal species were used, including Aspergillus niger, Aspergillus sp. 2, and Aspergillus sp. 1. The findings demonstrated that the fungus might speed up A. marina seedling growth. The plant's height, diameter, leaf width, and total dry weight were all altered as a result. Based on the study's findings, it can be said that Aspergillus niger provided the best growth for A. marina seedlings
