Abstract

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.

Abstract

The growth of population, agriculture and industries sector rapidly increaased in Branta  river area causes an increase in use of river water so the risk of pollution increases. Some of parameter such as BOD, COD and TSS could be able to affect the water quality. With secondary data of BOD, COD and TSS from some of Brantas river’s checkpoint, Some points were obtained that exceeded the quality standard that is on first point located in Surabaya River with 320 mg/l of TSS, seond point located in Tengah River with 28,2 mg/l of COD, third point located in Porong River with 390 mg/l TSS and fourth point located in Brantas river  with 15,6 mg/l of BOD. This is caused by the activities of the people around who pay little attention to the cleanliness of the river environment, such as throwing garbage on the banks of the river.

Abstract

The fertilizer industries in East Java Province has increased in scale of production, area and human resources in line with the increase in fertilizer demand in Indonesia by 5.67%. It causes increased emissions into the atmosphere which will affect health and the environment. Therefore, an air dispersion simulation was carried out to determine the maximum level of emissions released. This study uses a modeling approach with Aermod View software to simulate the process of dispersion of CO2, NOX, and TSP air emissions in the distribution of emissions. The results of the dispersion distribution model for SO2, NOX, and TSP emissions are at a distance of 500 - 600 m from the emission source. The dispersion simulation results of the SO2 show the highest concentration of 7.34 µg/m3. The dispersion simulation results of the NOX show the highest concentration of 9.791 µg/m3. Also, the results of the TSP show the highest concentration of 1.22 µg/m3. Based on Republic of Indonesia Government Regulation no. 22/2021 Appendix VII concerning Ambient Air Quality Standards for the SO2 of 150 µg/m3, the NOX of 200 µg/m3, and the TSP of 230 µg/m3, each emission parameter still meets the established emission quality standards.

Abstract

Petrokimia Gresik is one of the largest and most comprehensive fertilizer companies in  Indonesia, playing a major role in the food security sector. The superior fertilizer production is  ZA II fertilizer. The existence of a strong concern lies in the emissions produced in the production  process where the presence of gas can trigger environmental impacts if not properly managed and  controlled. Therefore, through methodLife Cycle Assessment (LCA) is able to identify and assess  potential environmental impacts in PT Petrokimia Gresik's ZA II fertilizer production process.  Approach done byEndpoint divided into human health, ecosystem quality, and natural  resourcesRecipe 2016. As a support for the identification carried out, software will be used in the  form of Open LCA type 1.11.0 and SimaPro type 9.4.0.2. The studies obtained show that there is  a unit process that is produced with the greatest impact on the drying unit system (drying) and  cooling (cooling) due to the causes of the chemicals used and the emission content released in the  form of ammonia (NH3) and carbon dioxide (CO2). With this impact, it is necessary to carry out  alternative solutions to reduce the risk of impacts that occur in the ZA II fertilizer production  process.

Abstract

Marine pollution is one of the national and international issues that the entry of dangerous substances due to human activities into the marine environments, therefore it will cause problems in changing ecosystems on the sea. Marine pollution can result from the disposal of domestic waste, industrial waste, radioactive substances, ship loading and unloading activities, and mineral mining offshore. The impact of pollution will disrupt the aquatic ecosystem, environmental quality, and environmental aesthetics. The international conventions for controlling marine pollution at the international level, that is International Maritime Organization (IMO) produce agreements to overcome pollution issues that occur due to oil spills and dangerous toxic goods which require preparation and action response to oil pollution in various forms, which threaten environmental sustainability maritime.

Abstract

Black Soldier Fly (BSF) larvae are one type of insect that has the potential to help reduce organic waste because they can act as decomposers by converting organic waste biomass into high-quality protein. In their utilization, adult BSF larvae are often used as a component in fish and livestock feed, and the leftover maggots can be utilized as a substitute material for NPK fertilizers. The nutrient content and quality of adult BSF larvae, however, depend on the treatment received during their development, including their feeding media. This study aims to investigate the effect of different feeding media on the protein content of BSF larvae, with the goal of identifying the best treatment for BSF cultivation. The review is conducted by analyzing data from literature related to maggot feed and its nutrient content. The highest protein content, based on the collected data, is found in BSF larvae fed with a combination of 30% leftover food and 70% fruit waste, with a protein percentage of 59.25%.

Abstract

In running the production process of this company requires a large volume of clean water. Meanwhile, the company's supply of clean water is only supplied by PDAM, second party supplies, and the results of the water treatment plant. This study aims to analyze the prediction of water demand for the balance between clean water suppliers and clean water demand based on increased production. This approach is carried out with a dynamic system model and with the help of stella 9.0.2 software. The methods used in this study are problem identification, making dynamic hypotheses, model validation, and model evaluation. from the simulation results show that the amount of production in years 2 to 10 has increased, namely in year 2 as much as 1396.41 tons and in year 10 it reached 1546.64 tons. in years 4 and 6 the water supply has decreased which is not proportional to the required water consumption. However, in year 6 to year 10, the volume of clean water supply continues to increase and has fulfilled the total volume of water demand. Therefore, a policy is needed to increase the supply of clean water from the PDAM or supply water from within the company itself, namely by expanding the land for water treatment plants or utilizing surface water sources, namely well water.

Abstract

The existence of slaughterhouses is important to fulfill the need for animal protein for consumers. Every day, slaughterhouses produce waste from their activities. The liquid waste generated contains high organic load. In this study, we focused on a constructed wetland system with Typha angustifolia plant as a phytoremediation medium to treat slaughterhouse wastewater. This plant was studied for its ability to remove the organic load of slaughterhouse wastewater in terms of BOD, COD, TSS, and NH3N parameters. This research begins with the construction of a reactor in the form of a container box with a size of 20cm x 21cm x 31cm which will be filled with soil (10cm), silica sand (2cm), and gravel (2cm). Acclimatization is carried out to enter the range finding test experiment, where the concentration of effluent exposure used is 25%, 50%, and 75% for a period of 7 days. Data analysis aims to compare the water quality in the reactor using the overal efficiency equation, which is then continued with the Anova test. Based on the research that has been done, Typha angustifolia succeeded in removing BOD by 97.90%, COD 98.95%, TSS 94.09%, and NH3N 94.61%. Anova test showed that concentration and detention time did not affect the effectiveness of plants in reducing waste.
