Abstract

The peel of Kepok banana (Musa paradisiaca L.) can be utilized as an environmentally friendly coagulant in the treatment of tofu industry wastewater. This study examined the effectiveness of the bio-coagulant derived from Kepok banana peel in comparison to the chemical coagulant Poly Aluminium Chloride (PAC) in reducing pollutant concentrations in the tofu industry "X". The coagulation-flocculation process was conducted at laboratory scale with varying coagulant doses of 0.4 g/L, 1.2 g/L, 2 g/L, and a control test. The mixing process involved rapid stirring at 200 rpm for 5 minutes, followed by slow stirring at 40 rpm for 10 minutes, and settling for an hour. The wastewater pH was optimized to 8. The results showed that a 0.4 g/L dose of Kepok banana peel reduced BOD levels by 29.8%, COD by 58%, and TSS by 41%. For comparison, a 0.4 g/L dose of PAC demonstrated higher effectiveness, reducing BOD by 26.8%, COD by 56%, and TSS by 28%.

Abstract

Domestic wastewater, which is categorized into black water and grey water, is one of the main sources of water pollution due to its high concentrations of Total Suspended Solids (TSS) and Total Coliform, both of which negatively impact human health and the environment. This study aims to evaluate the effectiveness of Aloe vera as a biocoagulant in reducing TSS and Total Coliform concentrations in domestic wastewater from Housing Complex X, Sirnabaya Village, Karawang Regency, as well as to compare its performance in gel and liquid forms. The research method applied was a laboratory scale experiment using the jar test. Wastewater samples were collected through composite sampling at three different times in one day (08.00, 14.00, 20.00 WIB). The Aloe vera biocoagulant was processed in two forms: gel and liquid. Dosage variations tested were 0, 10, 15, 20, and 25 mL/L. The results showed that the Aloe vera biocoagulant was effective in reducing both TSS and Total Coliform. In the gel form, with the dose of 25 mL/L reached the result 86% for TSS  and 76% for Total Coliform, meanwhile for the liquid form reached the result 76% and 73% with 10 mL/L dose. The superior performance of the gel form compared to the liquid is attributed to its more intact active compounds, such as acemannan for TSS and anthraquinones for Total Coliform.

Abstract

Domestic wastewater discharge remains a major factor contributing to the deterioration of river water quality, as untreated effluents are still commonly released directly into river systems. This concern is particularly evident in the downstream segment of the Kusan River tributary, situated in the villages of Sungai Lembu and Beringin. The intensifying expansion of residential settlements in the area has been identified as a key driver of pollution in the Kusan River, with its scale increasing annually. Environmental degradation arises when the pollutant load exceeds the assimilative capacity of the aquatic ecosystem. Under such conditions, the natural recovery process becomes protracted and increasingly ineffective, resulting in persistent contamination. This research is designed to assess the influence of surrounding anthropogenic activities on the water pollution index and the ecological condition of the Kusan River tributary in the aforementioned villages, within Tanah Bumbu Regency, South Kalimantan Province, employing the Water Pollution Index (WPI) methodology. Based on laboratory analyses, Total Suspended Solids (TSS) concentrations in the lower reaches of the tributary exceed 50 mg/L, thus surpassing the threshold set by Government Regulation No. 22 of 2021 concerning Water Quality Management and Pollution Control. Moreover, findings from the pollution index evaluation indicate that water quality in the study area ranges from good to lightly polluted, with index scores varying between 0.33 and 1.73.

Abstract

The growth of industry in Karawang Regency impacts the increase in burning activities in the production process, which has the potential to become a source of air pollution. These activities generate pollutants that are hazardous to humans and ecosystems. This research aims to analyze the meteorological factors influencing the distribution patterns of TSP pollutant concentrations, as well as to map the distribution patterns resulting from burning activities in the chemical industry using AERMOD View, during the dry and rainy seasons, which will produce the concentration values of pollutants received by receptors. The method used is quantitative, using an air pollutant dispersion modeling approach using AERMOD View. Secondary data consists of emission data, meteorological data, and topographic data. Data analysis was performed by comparing the AERMOD View modeling results across seasons. Furthermore, concentration values were compared with Ambient Air Quality Standards referred to in Government Regulation No. 22 of 2021. Based on the research, the combination of meteorological factors, wind direction, and wind speed are the main parameters. The pattern of pollutant dispersion is determined by the interaction between wind direction, distance, receptor elevation, when combined with the physical characteristics of the chimney and the amount of emission load released by the emission source, it will determine the magnitude of the pollutant concentration received by the receptor.

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.
