Abstract

Air pollution caused by industrial activities has become a critical issue due to its significant impact on public health and the environment. This study aims to model the dispersion of air pollutants in the form of carbon monoxide (CO) and nitrogen dioxide (NOâ‚‚) emitted from a biomass boiler stack at a steam supply industry located in Karawang Regency. The modeling was conducted using the AERMOD software, integrated with AERMET for meteorological data processing and AERMAP for topographical data input. Emission data were obtained from direct monitoring of industrial sources, while meteorological data were sourced from the Climate Data Store. The modeling was carried out for two seasonal periods, namely the dry season and the rainy season, to evaluate the influence of meteorological variables on pollutant distribution. The air quality modeling results indicated that the highest concentrations occurred during the dry season, with 1-hour and 8-hour CO concentrations of 22.46 μg/m ³ and 8.52 μg/m ³, respectively, and 1-hour and 24-hour NOâ‚‚ concentrations of 76.75 μg/m ³ and 22.71 μg/m ³, respectively. All concentrations remained below the established ambient air quality standards. The conclusion of this study indicates that seasonal meteorological conditions influence pollutant dispersion, with higher concentrations observed during the dry season compared to the rainy season; however, the levels remained within regulatory safety limits.

Abstract

The coastal area has a high likelihood of seawater intrusion, leading to the formation of brackish water. Brackish water is unsafe for consumption due to its high salt content, which exceeds 0.5 ppt. The purpose of this study is to identify the distribution of salinity by testing the well water of the residents in Tanjung Pakis Village, Karawang Regency. The sample determination method used is Systematic Grid Sampling. The grid used measures 1,000 x 250 m. In this study, 3 grids were used, each at different distances from the nearest coastline. Three samples were taken from each grid, resulting in a total of 9 samples. The parameter tested is salinity, which represents the salt content in the water. The method used to measure the salinity parameter is direct reading using a refractometer. The results of the study show that the highest salinity parameter value reached 120 ppt in Grid I, while the lowest salinity parameter value was 30 ppt in Grid II. The mapping results indicate high salinity values in Grid I, represented by a darker color. In Grid II, the salinity value decreases, indicated by a lighter color. An increase in salinity occurs in Grid III, shown by a darker color compared to Grid II.

Abstract

Tourism is an activity that is of concern to Indonesian people, especially beach tourism, such as at Siring Pagatan Beach, Tanah Bumbu Regency, South Kalimantan. This tourism is dominated by culinary, religious, and transportation activities which have an impact on increasing the creative economy of the community. However, these activities also have the potential to cause environmental and health problems due to gas emissions and noise. To avoid the impact, it is necessary to identify and analyze the ambient air quality and noise levels at Siring Pagatan Beach. This study is essential, considering the vast potential and development of tourism activities in the research area, which is close to residential areas. In the study area, the ambient air quality, in terms of total particulates; PM10; PM2.5; NO2; SO2; and CO were measured using Indonesian National Standard No. 19-7119.6-2005 in four locations, while noise levels were carried out in 2 two locations according to Indonesian National Standard No. 8427-2017 in the study area. The results showed that the total amount of total particulates; PM10; PM2.5; NO2; SO2; and CO are 60.23-90.15; 25.07-70.02; 14.66-48.01; 0.95-5.31; 14.46-26.48; and 1917.14-1382.86 g/m3. Meanwhile, the noise obtained was 52.00-52.20 dBA. The value of these environmental components is below the threshold value in Indonesia. However, with ongoing tourism infrastructure development activities, there is the potential for increased pollutant concentrations and noise levels at the research location, which may impact the surrounding community in the long term.

Abstract

Climate change is an increasingly pressing global issue, and greenhouse gas emissions are among its main drivers. Greenhouse Gases are gases found in the atmosphere that absorb and re-emit infrared radiation from Earth, causing an increase in Earth's surface temperature. The researcher aims to calculate and analyze CO2 emissions resulting from the identification of transportation activities on campus 1 of Singaperbangsa University, Karawang. The researcher uses direct observation. The primary data in this study are the numbers of vehicles and electronic devices, such as lights and air conditioners. The use of electricity results in a potential Greenhouse Gas emission of 19,982 kg CO2eq at Singaperbangsa University, Karawang, representing 56% of the total. Motorized vehicles have a potential greenhouse gas emission of 15,807 kgCO2eq at Singaperbangsa University, Karawang, accounting for 44% of the total. The total potential Greenhouse Gas emissions from electricity use and motorized vehicles at Singaperbangsa University, Karawang, amount to 35,789 kg CO2eq.

Abstract

Used cooking oil undergoes a decline in quality due to oxidation and hydrolysis reactions, characterized by an increase in the peroxide value and free fatty acid content. These reactions are triggered by repeated heating at high temperatures (175–180°C), contact with oxygen, and the presence of water from food ingredients during the frying process. This study aims to analyze the effect of the ratio of water hyacinth (Eichhornia crassipes) and rice husk (Oryza sativa L) as adsorbents on the purification of used cooking oil using the adsorption method. The ratio of water hyacinth to rice husk was varied to 100:0, 75:25, 50:50, 25:75, and 0:100, with a used cooking oil volume of 50 mL, an adsorbent dose of 15% (w/v), and a contact time of 120 minutes for each treatment. Water hyacinth was prepared through chemical activation using NaOH, while rice husks were carbonized at 300°C for 2 hours and activated using 10% NaCl. The peroxide value was analyzed using iodometric titration, while free fatty acids were analyzed using alkalimetric titration in accordance with SNI 3741:2013. The results of the study indicate that the ratio of 50:50 provides the most optimal adsorption efficiency, with a reduction in the peroxide value from 18.50 to 5.20 meq O₂/kg and free fatty acids from 1.20% to 0.24%, as well as efficiencies of 71.89% and 80.00%, respectively. The reduction in these parameters was influenced by the interaction between impurities in used cooking oil and the hydroxyl groups on water hyacinth lignocellulose, as well as the silanol groups and pores of rice husk charcoal.
