Abstract

The leaves of R. stylosa are a potential source of bioactive compounds for health and pharmacology. The composition of bioactive compounds in the leaves can be influenced by the ecological conditions and geographical location of this small island. This study aims to evaluate the toxicity and composition of bioactive compounds that are toxic in mangrove leaf extracts of R. stylosa from Maspari Island in coastal South Sumatra. A total of 1 kg of R. stylosa leaf samples were taken from Maspari Island then washed thoroughly to remove dirt, cut into small pieces, and dried in the sun using the indirect sunlight method covered with black cloth. The dried leaf samples were then pulverized into powder, and as much as 100 grams of fine powder was macerated with 96% ethanol solvent in a ratio of 1:10 (b/v). The maceration process was carried out for 1 x 24 hours, then the maceration solution was filtered and evaporated using a rotary evaporator at 60°C to become a concentrated extract. Toxicity tests were carried out using the Brine Shrimp Lethality Test (BSLT) method, while the identification of toxic bioactive compounds was carried out through phytochemical tests, total phenol tests, and GC-MS analysis. The test results showed that the LC50 value of R. stylosa leaf extract was 393 mg/mL (moderately toxic). The total phenol content was 442.82 (gGA/g), and the bioactive compounds identified included alkaloids, flavonoids, saponins, terpenoids, and acids such as Hexadecanoic acid, methyl ester, and trans-13-Octadecenoic acid, methyl ester.

Abstract

Water quality in the form of turbidity, colour, odour, taste and suspended residue are significant issues in Sungsang Banyuasin. The filter utilizes a filtration method to remove solid particles and contaminants. The research site consists of Sungsang, Sungsang II, and Sungsang III areas. The purpose of this study was to determine the water quality in the form of colour, taste, odour, turbidity, suspended residue, and salinity, as well as the ability of the filter to overcome water quality. Filtration consists of sedimentation, filter membranes, and filter media consisting of zeolite, silica, anthracite, ferrolite, activated carbon, and bioring. Water quality measurements used organoleptic to determine odour and taste, handrefractometer to measure salinity, direct reading to measure suspended residue, and spectrophotometry to measure colour and turbidity. The breech water was odourless and tasteless, and the suspended residue value ranged from 17-19 mg/L below the quality standard of 50 mg/L. Colour and turbidity values are greater than 50 on their respective scales and salinity values range from 11-13 ppt. The filtration process successfully reduced the values of suspended residue, colour, turbidity, and salinity.

Abstract

In coastal environments and the ecosystems, including seagrass ecosystems, heavy metals can lead to pollution. This study goal is to analyze the concentration of heavy metals in water based on safety standards for marine organisms. Water samples were collected from two locations: Jeralangan HamLet and Cukuh Nyai HamLet in Pahawang Island, Lampung, Indonesia. Water quality parameters were measured in situ. Heavy metals such Pb, Cu, Ni, and Zn were prepared using Wet digestion method and the concentrations were measured using Atomic Absorption Spectrophotometer (AAS) SHIMADZU AA-7000. At the same location, the highest concentration of was observed for Zn 0.406 mg/L at station 2, while the lowest concentration was recorded for Cu 0.019 mg/L. The concentration of heavy metals Pb, Cu, Ni and Zn in water has exceeded the quality standards for marine biota and marine tourism.These research can be used as a basis for future planning in the management of Pahawang Island’s coastal environment.
