Abstract

Background: The cement industry is one of the main contributors of pollutant gasses in the environment through stack emissions.Aim: This study aims to model the dispersion of SO2 and NO2 gasses and to determine the area of the dispersion by American Meteorological Society – Environmental Protection Agency Regulation Model or AERMOD has been utilized by PT. Semen Tonasa (Tonasa Cement, Ltd.).Methods: Meteorological data from AERMENT was collected from reanalysis of MM5 data. While topographical data was extracted from SRTM30 satellite data. The model was carried out for a year, to cover both the dry and rainy season.Results: The result of the modeling showed that the peak value of the concentration of SO2 and NO2 pollutants for one hour are 135 μg/m3 and 160 μg/m3 respectively (quality standards of SO2 and NO2 are 900 μg/Nm3 and 400 μg/Nm3). The area of dispersion tends to be in the eastern area, such as District Minasatene (Sub-district Bontoa, Kalabbirang, Minasatene dan Biraeng), District Bungoro (Sub-district Biringere, Sapanang, Mangilu, Bulu Tellue) and District Labakkang (Sub-district Taraweang). Key words: Spatial analysis, AERMOD, AERMOD, cement factory, exposed area, SO2 and NO2

Abstract

This study aims to synthesize Fe nanoparticles by bioreduction using the phytoplankton extract of S. platensis that acts as a reducing agent. Synthesis process is done by adding extracts of S. platensis to a solution of 1 mM FeCl3. The formed nanoparticles characterized by UV-Vis spectrophotometer, Fourier Transform Infra Red Spectroscopy (FTIR), Scanning Electron Microscopy (SEM) and Energy Disperse X-Ray Spectroscopy (EDX/EDS), X-Ray Diffraction (XRD) and X-Ray Flourosence (XRF). The results showed that the solution of Fe3+ ions can be reduced by phytoplankton extract of S. platensis Fe nanoparticles formed. The average size of the particles based on the Debye-Scherrer equation was 68.10 nm. While the morphology of Fe nanoparticles was spherical shape.

Abstract

The determination of lead (Pb) and cadmium (Cd) levels in sediment samples in Spermonde waters has been determined. Sampling was carried out in river and sea estuary waters. The method used in the analysis of Pb and Cd is the one specified by SNI 06-6992.3-2004 and SNI 06-6992.4-2004. Based on the Decree of the Minister of Environment No. 51 of 2004, the general condition of Spermonde waters still supports the activities of marine organisms. The results showed that Spermonde waters received more Pb metal input than Cd metal. Pb metal content in river estuary and sea waters averaged 17.38 ppm. The highest Pb metal content is found in Lanjukang Island and Bone Tambung Island, each ranging from 20.88 ppm and 20.19 ppm. Meanwhile, the lowest Pb metal content on Barang Lompo island was 9.86 ppm. The detected metal content of Cd is only found in the Barrang Lompo and Kondong islands of Bali, each ranging from 1.04 ppm and 0.19 ppm, while the other locations Cd metal are undetectable. Based on the SQG value, the content of Pb and Cd in sediments in Spermonde waters is still in the standard range for sediment that has not been contaminated.

Abstract

The Bone sugar factory discharges its liquid waste into the Teko River water body. The Teko River is widely used for agricultural and fishery purposes, so it is necessary to maintain the quality of the water to suit its designation. Liquid waste from the Bone sugar factory can affect the water quality of the Teko River. The purpose of this study was to determine the water quality status of the Teko River due to the discharge of waste water from the Bone sugar factory. Observations were made on the water body of the Teko River from the up stream and down stream of the disposal of sugar factory wastewater at 3 stations. Station 1 is the point before the discharge of wastewater, station 2 is the point of discharge of wastewater and station 3 is the point after discharge of wastewater, the recipient of the impact. The results of the research conducted on the Teko river water body showed that the status of water quality at station 1 was the category of lightly polluted, station 2 was in the category of lightly polluted and station 3 was in the category of meeting quality standards. Determination of water quality using the Pollution Index method according to Minister of Environment Decree Number 115 of 2003 using class II river water quality standards according to Government Regulation Number 22 of 2021quality standards according to Government Regulation Number 22 of 2021.
