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.

Pemetaan Persebaran Emisi Pembakaran dan Pengecatan Area Produksi Drum Distributor Aspal

Fanesa Fathimah Zahroh — 2023-10-31

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..

Perencanaan Pendekatan Analisis Sistem Causal Loop Diagram Pada Pengolahan Sisa Spunbond Produksi Industri Tekstil Sebagai Bahan Baku Produksi Berbasis Low Waste

Syadzadhiya Nisa — 2024-01-29

Industry in Indonesia is growing from year to year along with economic, technological, and scientific developments. The industrial waste problem cannot be separated from the overall waste problem. These problems include operational technical, legal, funding, social, and institutional or management aspects. Spunbond production in companies in the non-woven textile industry produces products of poor quality. By reducing the accumulation of production waste in the form of spunbond which is processed in the recycle process, the remaining production waste in the form of spunbond becomes raw material for production in the form of polypropylene (PP) plastic seed chips or finished products from recycling units. This research aims to analyze the processing of production waste which is processed in the recycling unit. This approach is carried out using a dynamic system model and with the help of Stella 9.0.2 software. The methods used in this research are problem identification, creating dynamic hypotheses, model validation, and model evaluation. The simulation results show that the amount of recycle processing can process around 10.86% of the production which produces 100,000 tons/day in production. Therefore, a policy is needed to enlarge the process of recycling so that the cycle used for the production of raw materials is better without the accumulation of waste left over from unprocessed production.

Okik Hendriyanto Cahyonugroho — 2023-10-31

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.

Syadzadhiya Qotrunada Zakiyayasin Nisa' — 2023-10-31

The high potential for economic growth in the world has extreme threats from reduced energy supplies, use of fossil fuels, high dangerous gases and electricity prices. According to the European Commission in 2010, the cement industry is an industry that requires heat and electrical energy, so around 40% of all operational costs are spent on energy procurement. The cement industry is one of the largest contributors to air pollution in the world due to the level of energy consumption and potential dust emissions. This is a major factor in the source of air pollution. Air emissions from the cement industry contain chemicals that are harmful to health and the environment. Air pollution occurs if the composition of substances in the air exceeds specified thresholds. The presence of chemicals that exceed the limits can endanger health. One of the impacts that arise from the cement production process is the occurrence of acid rain or acidification. The aim of this research is to analyze and identify the stages that contribute the most to the potential impact of acidification, and present recommendations for improvements in an effort to reduce the environmental impact of the cement production process. The cement production process begins with the Kiln Mill, Clinker and Finish Mill stages. The method used in this research is Life Cycle Assessment. The scope used in this study is gate to gate. Data on production processes is analyzed using SimaPro 9.5 software. The Kiln Mill process is the stage in the cement production process that contributes to the largest acidification impact with a value of 0.556 kgSO2 eq/ton. The recommended alternative repair program is the use of Wet Type Flue Gas Desulfurization (FGD) and planting trees in industrial environments.

Komang Kurniawan — 2023-10-31

The maritime industry in Indonesia is increasing every year, especially in the maritime service sector. Tanjung Perak Port is one of the areas in Surabaya whose operational activities focus on the maritime service sector. The operational activities of the maritime service sector produce emissions from both ship chimneys and chimneys resulting from the burning of raw materials for the maritime service industry. To find out directly the emissions produced, a test was carried out on the chimney at one of the maritime service sector companies. Measurements were made by testing the parameter concentration of SO₂. From the measurement results obtained, it will be modeled into the aeromod software so that the distribution of emissions generated around the maritime service industry area can be known. After modeling it in the AERMOD software, the results show that the concentration of SO₂ produced by the maritime service industry has been dispersid from a distance of 500 meters from the chimney resulting from the combustion of raw materials for the maritime service industry. With the results obtained, the solution to reduce the concentration of SO₂ produced is to modify the chimney that produces emissions so that the emissions produced can be reduced and the emission distribution area can be reduced so that it does not have a wide impact on the surrounding area

Pola Sebaran Parameter Air Limbah (COD, BOD, dan Amonia) dari Kegiatan Eco Resort dan Wisata Bahari di Perairan Laut Flores

Raden Kokoh Haryo Putro — 2023-10-31

Wastewater generated from the operation of the Eco Resort and Marine Tourism activities
originates from domestic activities. Wastewater from domestic activities is treated at the
Sewage Treatment Plant (STP) and discharged into the sea. This research aims to provide a
deeper understanding of the spatial distribution patterns of wastewater parameters (COD,
BOD, and Ammonia) from Eco Resort and marine tourism activities in the Flores Sea. This
study was conducted during the west season in January 2021, followed by modeling using
MIKE 21 EcoLab, to determine the magnitude and distribution patterns of pollution in the
Flores Sea. The modeling results show that outfall 3 significantly influences the increase in
COD and BOD concentrations, especially during peak tide conditions and when the tide is
receding. Another factor causing an increase in COD and BOD values is the proximity of the
outfall to the wastewater discharge point. Based on the simulation results, the increase in
ammonia concentration is influenced by environmental factors and tidal changes. During low
tide conditions, the seawater current from the Flores Sea flows northward, transporting
wastewater from outfalls 1 and 2 to the north, resulting in increased ammonia concentrations
in that area.
