Abstract

S. alba is a mangrove that is commonly found on the east coast of Banyuasin. Endophytic fungus can produce a functional compound e.g antibacterial. The purpose of this study is to determine the type, the increase in diameter of colonies and the antibacterial potential in endophytic fungus of S. alba. The research method used were by the isolation of endophytic fungus from leaf, stem and root, the identification of endophytic fungus, the measurement of colony diameter in endophytic fungus and antibacterial activity test using paper disc method. The results of this study found the two genera of endophytic fungus with four species of Aspergillus sp1., Aspergillus sp2., Paecilomyces sp1., and Paecilomyces sp2. The increase in diameter for each colony of endophytic fungus shows the difference every day. Aspergillus sp1. The exponential phase has been visible on the third day with an average diameter increase of 33.70 mm / day. The exponential phase of Aspergillus sp2 was visible on the third day with an diameter increase of 37.74 mm/day. In the endothelium fungi Paecilomyces sp1, the exponential phase was visible on the third day to the seventh day with diameter increase of 13.57 mm/day to 38.07 mm/day. Exponential phase of Paecilomyces sp2. was visible on the third day to the sixth day with diameter increase of 25.25 mm/day to 75.21 mm/day. These four types of endophytic fungus are resistant to bacteria E. coli and S. aureus. Aspergillus sp2. endophytic fungus has the highest inhibitor potency of 14.49 mm in E. coli bacteria. The endophytic fungus Paecilomyces sp2. inhibits bacterial growth of S. aureus with the highest inhibitory potency of 11.61 mm.

Abstract

Squid belongs to the phylum Mollusca, specifically the Cephalopoda group (soft-bodied animals) which is one of Indonesia's fisheries resources. One of the regions abundant in squid fisheries resources is the waters of Majene, West Sulawesi Province. This research aims to determine the distribution of the captured squid's size structure and growth patterns in the waters of Majene. Squid sampling was conducted in July–August 2023. The sampling procedure involved randomly selecting squid catches from fishermen in the waters of Majene with a sampling frequency of once a month, resulting in a total of 102 specimens of Loligo sp. squid, consisting of 82 males and 20 females. Overall, the range of mantle length obtained for Loligo sp. squid was 90–180 mm, with a weight range of 26.08–306.19 g. The majority of male squid caught during the study had a mantle length in the range of 127–138 mm, while female squid had a mantle length range of 115–126 mm. Based on statistical analysis, the growth pattern of combined and male Loligo sp. squid in the waters of Majene exhibited negative allometric growth, meaning that weight increase was more dominant than length increase. In contrast, female squid exhibited positive allometric growth, indicating that weight increase was more dominant than length increase.
