“…Pergerakan arus berfungsi menyuplai makanan dan oksigen, kemudian juga membantu menghilangkan akumulasi kotoran dan sedimen pada polip karang yang menempel. Arus juga mempengaruhi pembuahan dan penyebaran ikan karang, terutama pada tahap pemijahan dan larva (Nybakken, 1992;Nontji, 2007;Maharbahakti, 2009). Haris dan Yusanti (2018) menjelaskan semakin tinggi kecepatan arus maka kandungan oksigen dalam air akan semakin tinggi pula.…”

The large potential of marine fisheries owned by the City of Bengkulu can be an economic source for the local community. The fish potential comes from pelagic fish and reef fish. One of the reef fish is the parrot fish (Scaridae). Parrot fish in Bengkulu City are obtained from Tikus Island which are sold on Malabero Beach. The purpose of this study was to analyze the ecobiological aspects of parrot fish (Scaridae) in Tikus Island waters, Bengkulu City. The results of this study are expected to provide information in the form of valid data regarding the ecobiological aspects of parrot fish (Scaridae) in Tikus Island waters, Bengkulu City. In this study, data collection to look at ecological or environmental aspects was carried out by direct observation in the field at 3 stations, while biological aspects, namely food habits (amount/type of food), were observed through a microscope in the laboratory. The results of water parameter measurements, namely the temperature at station 1 ranged from 28-29 0C, station 2 is 29 0C, station 3 is 29 0C. pH value at station 1 is 7.0-7.3, station 2 is 7.3-7.7, station 3 is 6.5-7.1. Salinity values at station 1 is 31 ppt, station 2 is 30 ppt and station 3 is 31 ppt. Dissolved oxygen (DO) at station 1 ranged from 5.6-6.3 mg/L, station 2 5.2-5.3 mg/L and station 3 5.6-6.1 mg/L. The water brightness at station 1 is 9.2 m, at station 2 is 6.6 m and at station 3 is 7.4 m. Current velocity at station 1 ranges from 0.09-0.11 m/s, station 2 are 0.08-0.14 m/s, and at station 3 ranges from 0.05-0.09 m/s. Water depth at station 1 is 9.2 m, station 2 is 7.3 and station 3 is 7.5 m. These results indicate that Tikus Island water have a good environment for survival and habitat of parrot fish (Scaridae) or other marine biota. Furthermore, the biological aspects studied are food habits. Based on the identification results, 4 groups of food types were found in the parrot fish stomach, namely phytoplankton, zooplankton, sand coral, and were not identified. The percentage of food groups found from phytoplankton, zooplankton, sand coral, and not identified were 53%, 3%, 15%, 29%, respectively.

“…Southeast Sulawesi's waters are home to soft corals, one of them is the Lobophytum sp. [7]. A few studies on the chemical and pharmaceutical aspects of this genus have been reported, including three cembrene diterpenoids named Lobophylins F-H from L. crassum growing in Taiwan [8] and lobocrasols A-D were identified from Vietnamese's L. crassum which have potential as anti-inflammatory [9], and Chinese's L. crassum produced polyoxygenated cembranoids namely lobophycrasins A-D and hum ulisin A [10].…”

The article aims to describe the findings of chemical and pharmaceutical aspects of Lobophytum sp. from Southeast Sulawesi, Indonesia. Ethylacetate extract was fractionated by Vacuum liquid chromatography (VLC). Toxicity was evaluated by BSLT test, and the phytochemical screening and LCMSMS method were used to determine the chemical composition and molecular docking for in-silico study. The results showed that the ethylacetate extract was produced seven fractions namely Fraction A-G. The weight of each fraction was A (12.8% w/w), B (9.7%), C (10.1%), D (2.0%), E (7.0%), F (25, 3%) and G (11.5%). The toxicity potency of Fraction B is the most toxic with LC50 (mg/L) 26.70 ± 0.58. LCMSMS data indicated that the fraction B contains 19L-glukocyl-14-deoxy-11,12-didehydrographoside, 3-isoazmalicine, abietraticine, arachidonic acid, neociwujiaphenol, oxyphyliacinol, saurufuran B and some unidentified compounds with molecular formulas C37H46O7, C35H44O5, and C20H26O2. Based on computational simulations, Ar-Abietatriene and 3-Isoajmalicine have the potential to inhibit CDK-6. These compounds hinder the progression of the cell cycle and the proliferation of cancer cells by forming molecular interactions with residues Ile19, Val27, Ala41, Val77, Phe98, Val101, Leu152, and Ala162. This suggests their potential as anticancer agents. Thus, Fraction B can be continued for the anticancer evaluation.
