Abstract

Production activities in the palm cooking oil and margarine industry generate emissions, both from combustion and non-combustion processes. This analysis aims to determine the results of the emission dispersion model from immovable sources on ambient air quality using AERMOD Software in the area around the Industry. The AERMOD modeling method is carried out by using generated emission load data, topography and meteorological data of activity locations for the last 10 years with air pollutant parameters measured including Particulates (TSP), Sulfur Dioxide (SO2) and Nitrogen Dioxide (NO2). After running the data, the results of the air emission dispersion modeling show that the highest concentration of emissions is located in settlements that are to the southeast of industrial emission sources. With the concentration of each parameter, namely for SO2 it is at 3.65 mg/Nm3 at a distance of 537 meters from the emission source, the NO2 parameter is at 5.98 mg/Nm3 at a distance of 497 meters, and the particulate parameter is at 1.31 mg/Nm3 with a distance of 498 meters. Distance can affect the emission concentration, namely the farther the distance from the emission source, the lower the emission concentration. Modeling using AERMOD shows that the dispersion of emissions on ambient air quality around the palm oil industrial area still meets the quality standards which refer to Government Regulation Number 22 of 2021 Appendix VII concerning Ambient Air Quality Standards.

Abstract

The condition of water quality in Indonesia is one thing that really needs more attention to maintain its stability. This is because there are several inhibiting factors, one of which is the activity and/or business of an industry. PT X is an activity and/or business engaged in coal mining. As operational activities progress, the results of operational activities will be processed first in the WWTP and will later be discharged into the river body. The rivers in this activity and/or business area include the Bai River, Senibung River, Gulang-Gulang River, Sempayau River, and Rapak River. This research was conducted to determine the quality of the river water. The method used is to identify the water quality of the Bai River, Senibung River, Gulang-Gulang River, Sempayau River, and Rupak River using Mike21 software by modeling and simulating data in 2 scenarios, namely during the dry season and rainy season. The overall simulation results for average and minimum discharge conditions in the rainy and dry seasons show the distribution of TSS (mg/l) in the Gulang-Gulang River, which has the maximum concentration of TSS with a maximum distribution of 900 m, Rapak River 1600 m, River Sempayau is 1200 m away, Senibung River is 1700 m , Bai River is 1700 m.

Abstract

Changes in land cover that were originally limited production forest areas were converted into mining areas causing environmental degradation. The I18 revegetation land was originally a forest area with a denudational hilly landform covered with various tropical forest vegetation of Kalimantan converted into a coal mining area. and to be returned to forest areas through land rehabilitation. The purpose of this study was to analyze the rate of erosion in sparse and dense cover crop areas in the restoration of reclamation land on I18 revegetation land. This research uses survey methods and field mapping in data collection and processing. Vegetation density data was collected at 20 sample points by purposive sampling using the quadrat transect method. Determination of the erosion rate using the stick method with details of 12 sticks in the rare cover crop area and 6 sticks in the dense cover crop area with volume weight testing using laboratory methods referring to SNI 03-3637-1994 and descriptive analysis. The results showed that the erosion rate value of the cover crop area was rarely 161.13 tons / ha while the dense cover crop area had an erosion value of 1.57 tons / ha. Cover crop areas rarely have a higher erosion rate than dense cover crop areas, more susceptible to soil damage with an area reaching 55.46% of the I18 area has the potential for erosion so that it needs improvement through conservation.

Abstract

Waste pollution is a serious problem facing the environment due to human activities, including household and industrial waste. Domestic waste originates from households and public facilities, while industrial waste is generated by various industrial sectors. Mixing domestic and industrial waste can create a pollution index that measures the level of environmental pollution. The pollution index is an important tool in monitoring water and environmental quality, helping to assess the impact of waste on aquatic ecosystems. This research aims to develop a pollution index that combines domestic and industrial waste components. Pollution parameters such as BOD (Biological Oxygen Demand), COD (Chemical Oxygen Demand), TSS (Total Suspended Solid), DO (Dissolved Oxygen), Total Coliform and pH were measured in water samples. The pollution index is calculated based on the measured parameter values, with a certain weight for each parameter based on the level of impact on the environment. The research results show that there is a relationship between industrial activities and the level of environmental pollution. Although domestic waste generally contributes to parameters such as BOD, COD, pH, TSS, Total Coliform, industrial waste has a significant effect on pollutant content in aquatic environments. The proposed pollution index is able to identify sources of pollution more accurately so as to enable more effective mitigation efforts.

Abstract

Increasing the daerah of the coal pit and disposal, planned additional outlet points in the project daerah (port activities). Wastewater in the form of rainwater runoff in the stockpile, to the washing of materials containing heavy metals, will enter the Settling Pond before being discharged into the X tributary. A numerical approach using MIKE 21 software which was applied taking into the western and eastern seasons. It was found that the highest temperature concentration reached 26°C, at outfall-1.7 km in the west and east seasons. The highest pH concentration in the east season reached 6.139, at outfall-1.7 km. The highest TSS concentration reached 15.0 ppm, at distance of 0.4-0.6 km in the west and east seasons. The highest Fe concentration reached 0.952 ppm, at outfall-0.25 km in the west and east seasons. Also, the highest Mn concentration reached 0.448 ppm, at distance 0.25 km in the west and east seasons. Based on PP no. 22/2021 Appendix VI Class 2 National Water Quality Standards, the temperature parameter Dev 3°C, the pH parameter 6-9, the TSS parameter 50 ppm, and the Fe and Mn parameters are not required, so only the pH parameter does not meet the quality standard.

Abstract

Aspal production in Indonesia continues to increase in line with road construction developments. One of the asphalt distributor companies in Gresik Regency is a distributor that contributes a significant role in the construction of national and provincial roads. With the increasing distribution of aspal, the emissions from burning and painting the raw materials for asphalt drums also increase so that the emissions produced will also have an impact on the environment around the production area. Under these conditions, the purpose of this research is to find a solution to the resulting emissions which have a significant impact on the environment. This study measures emissions from each production area chimney, which later results from emission measurements will be modeled in the Aermod software to determine the distribution area of emissions resulting from the combustion process and aspal drum painting. From the modeling results, it was found that the concentration of SO2 contributed significantly to the distribution of emissions around the production area. Therefore, with the modeling that has been done, the solution that can be given is the addition of chimneys in the production area, considering that there are still a lot of land areas in the asphalt distributor company and can be used for adding chimneys. With the addition of the chimney, it is expected that the emissions produced can be reduced and the emission distribution area can also be reduced..

Abstract

The total upstream surface water pollutant load has a lower value than the total downstream surface water pollutant load. Water flows from upstream to downstream which causes changes in water quality, therefore a study was conducted with the aim of knowing the effect of the amount of upstream surface water pollutant load on the amount of downstream surface water pollutant load in Kali Baru, South Jakarta. The analysis was conducted using a simple linear regression method with the predictor variable being the upstream surface water pollutant load (X) and the response variable being the downstream surface water pollutant load (Y). The results show a constant value (a) of 0.374 while the slope value (b) is 1.022 so that the regression model Y = 0.374 + 1.022 X is obtained. From the data it can be concluded that the amount of upstream surface water pollutant load has an influence on the amount of downstream surface water pollutant load of 0.374%, while 1.022% and the rest are influenced by external variables. Both variables have a strong relationship. The influence of the two variables is that if the amount of pollutant load entering the upstream surface water body increases, the amount of downstream surface water pollutant load will also increase.

Abstract

Nickel mining activities have negative impacts on the environment, one of which is a decrease in air quality due to increased concentrations of air pollutants. Types of pollutants emitted from mining activities, including particulates, SO2, PM and NOx. Therefore, an air dispersion simulation is carried out to determine the maximum level of emissions released from the nickel mining process. This study uses a numerical modeling approach with Aermod View software to simulate the process of dispersion of SO2, PM and NOX air emissions in the distribution of emissions from nickel mining activities. Based on the simulation image of SO2 NOx gas dispersion, and particulates are scattered westward from the emission source/chimney following the wind direction. The dominant dispersion of SO2, NOx and particulates towards the west corresponds to the dominant wind direction. The highest SO2 concentration is around 22.57 x 10^-9 g/Nm3 which is located at a distance of approximately 100 meters from the emission source. The highest NOx concentration is 15.63 x 10^-9 g/Nm3 which is located at a distance of approximately 100 meters.

Abstract

Keeping the community comfortable while developing is very important and needs to be considered. Besides climate and air quality, another thing that must be considered is noise level. One of them is in Pasar Minggu, South Jakarta in the construction of Nusantara Student Dormitory Building. This journal aims to model the noise level as a reference material for the health of workers in the activity environment and calculate compensation to the local government or community due to the noise caused. To achieve this goal, the classification of points and sampling time is carried out. Each parameter affects the noise measured in dB. The parameter that most affects the presence of many activities in that period is the one with the highest weight. Then, in the form of noise contour modeling, the values of several parameters were analyzed. The results of the modeling show that at the location of the construction activities of the dormitory building there are several periods of time in which the weight of the noise exceeds the quality standard. The result of the highest Leq average measurement is 59.7 dB obtained at 17.00-22.00 WIB, while the highest Ls value is obtained from the 3rd sampling point of 60.4 dB. From the data, it is known that the noise level exceeds the quality standard set for residential areas. The standard set is 55 dB based on the Decree of the Minister of Environment No. 48/MENLH/11/1996.
