This study aimed to examine the content of lead (Pb) accumulated in leaves. Sampling used purposive sampling as a sampling method at four gas stations in Palu City. Pb levels were determined by atomic absorption spectrophotometry (AAS) at the Laboratory of Analytical and Environmental Chemistry, Department of Chemistry, Faculty of Mathematics and Natural Sciences, Tadulako University. The results showed that the highest to lowest lead absorption in the leaves was Syzygium myrtifolium Walp; 0.75 mg/l from Tawaeli gas station, Bouganvillea spectabilis Willd; 0.67 mg/l from Maluku gas station, Polyalthia longifolia var. pendula; 0.67 mg/l at Yos Sudarso gas stations, and Dracaena reflexa Lam; 0.58 mg/l from Diponegoro gas station. The concentration of lead (Pb) found in each plant from gas stations is still below the maximum threshold set by SNI 01-7387:2009, which is 0.5-3 ppm. The ambient air content around the gas station is still below the air quality standard for measuring the lead (Pb) 2 g/m3 parameter.","PeriodicalId":8780,"journal":{"name":"Biocelebes","volume":"126 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91447032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The density of the population results in varied activities so that the waste produced in various types, quantities and sizes can be distributed to the mangrove area either through rivers or carried by the wind. The purpose of this study was to determine the type and amount of waste in the mangrove ecosystem in Kupang City. The method used is observation. Sampling was carried out by installing a transect perpendicular to the sea along 70 m at the place with the highest abundance of waste and the thickness of the mangrove reached 50-100 meters. There are 6 transects installed at the study site and each transect is divided into three zones consisting of three quadrants with a size of 30 x 10 m2. The distance between quadrants is 20 m with the first quadrant being at the first point where mangroves are found. The results of the study found that the composition of the types of waste scattered in the mangrove ecosystem of Kupang City were 88,91% plastik with a total of 15,628 pieces, cloth (4,21%) with a total of 640 pieces, other waste (3,97%) with a total of 604 pieces, cork/foam (1,18%) with a total of 148 pieces, rubber (0,57%) with a total of 86 pieces, metal (0,29%) with a total of 44 pieces, glass and ceramics (0,15%) with a total of 11 pieces, then paper and cardboard (0,05%) with a total of 7 pieces.

Samples of E. sublimata were collected from the mountane forests of the Lore Lindu National Park (LLNP), arround Sedoa village, Lore Utara District, Poso Regency The objectives of the research were to analyze the secondary metabolite compounds in E. sublimata plants and to determine the antibacterial activity of E. sublimata leaves extract in againts Salmonella thypii bacteria. Plant samples were extracted by maceration methods with 96% ethanol as a solvent. Actibacterial activity was tested by using agar well diffusion methods. The experiment was designed by Completely Randomized Design (CRD) with seven different concentration of E. sublimata extract (15, 25, 50, 75 and 85%). Extract and standard drugs were prepared in double-distilated water using Nutrient Agar tubes. 2% Chloramphenicol as standard drugs was used as a positive control and sterile aquadest was used as a negative control. The inhibition zone of bacteria and yeast growth around the disk was measured after 18 to 24 h incubation at 37°C. The results showed that the stem contains alkaloids, flavonoids, terpenoids, tannins and saponins. The rhizome containts alkaloid, flavonoids, terpenoids, tannins and saponins, the flowers containts alkaloid, terpenoids and tannins, while the leaves containts tannin and saponin compounds.

Further identification of the micromorphological character of pteridophyta (Scales and Trioma) was carried out at the Laboratory of Botany Of Biology Faculty of MIPA Gorontalo State University. Determination of pteridophyta diversity index using Sahon Wiener formula while phenetic relationship data is analyzed using gower General Similarity Coefficient formula on MVSP softwere.
