Abstract

The water of Kali Jagir, Surabaya, used as a raw water source, has been contaminated with high levels of BOD, COD, and permanganate. Therefore, this research seeks to address these issues by combining slow sand filtration with various media, including geotekstil and activated carbon. The study aims to optimize this combination in reducing parameters such as permanganate and total coliform in the raw water. The research methodology includes literature review, testing of raw water characteristics, preparation of slow sand filter reactors, preparation of filter media, and testing of media variations with an observation of organic and bacteriological pollutant removal efficiency. The results show that the combination of filter media involving sand, activated carbon, and geotekstil is effective in reducing organic pollutants. Geotekstil aids in the growth of the schmutzdecke layer and facilitates cleaning, while sand and activated carbon tend not to support such growth. Moreover, the optimum schmutzdecke growth time varies depending on the type of media used. These findings have significant implications for raw water treatment in industrial areas vulnerable to pollution, resulting in quality drinking water and addressing the frequent clogging issues in slow sand filters.

Abstract

One of the rivers in Bojonegoro Regency is the Gandong River where the surrounding community uses the Gandong River for irrigation of agricultural land, transportation facilities, and household activities. The decline in water quality along the river is caused by factors such as population density, waste from activities, and the use of rivers that are not in accordance with their uses. This study aims to determine the quality of surface water and determine how to control water pollution in Gandong River, Bojonegoro Regency. The purposive sampling method was used to determine the sampling location at two points, namely the upstream and downstream parts of the river. Data analysis uses a quantitative approach and describes the results of research observations which are then compared with water quality standards that have been determined based on PP No. 22 of 2021 concerning the Implementation of Environmental Protection and Management. The condition of the Gandong River water quality seen from the measurement results on the BOD parameter at point 1 and point 2, namely 6 mg/L and 7 mg/L, does not meet the quality standards. While the parameters TDS, TSS, pH, COD, DO, and Total Coliform still meet the quality standards. To control pollution in the Gondang River, a strategy of periodic inspection of river water quality is needed even though most river water quality parameters are still within the quality standards.

Abstract

Markets are places that facilitate buying and selling activities and are visited by many people, it making them vulnerable to the spread of a disease that can come from virus-carrying animals or inadequate sanitation. A healthy market should have good sanitation, such as adequate availability of water as sanitary higiene with adequate quality. Water used for sanitary hygiene purposes must be protected from pollutant sources and safe from contamination, and meet quality standards according to Regulation of the Minister of Health No. 32 of 2017. Therefore, to determine the quality of water that will be used to meet the sanitation needs of the market, this study measured the quality of clean water directly at three points around the location of the “Pasar Agro” development plan. Water quality measurements are carried out using methods according to the Indonesian National Standard according to each parameter to be measured. Based on the results of the measurements carried out, there are two chemical parameters that have not met, namely manganese and detergent parameters, as well as biological parameters in the form of total coliform. Correlation testing was carried out using Minitab 17 software on water chemistry parameters to determine the relationship between parameters, and it was found that there were only a few parameters that were related to each other.

Abstract

The amount of surface water pollutant load in the upstream tends to be lower when compared to the amount of surface water pollutant load in the downstream, this is due to the flow of water flowing from upstream to downstream and resulting in changes in surface water quality. Therefore, the purpose of this study is to understand the relationship between the level of surface water pollutant load in the upstream and downstream areas of Greges River, Surabaya by utilizing SPSS 23 software. The analysis method utilized refers to the simple linear regression method. The results of the analysis showed that with a significance level of less than (<) 5%, it can be concluded that there is an indication of an acceptable relationship between upstream surface water quality and downstream surface water quality. Simultaneously, the upstream surface water quality has a significant effect on the downstream surface water quality of Greges River, with the level of relationship reaching 85.7%, meaning that there is a very strong linear relationship between the upstream surface water quality and the downstream surface water quality it produces.

Abstract

Nitrogen is one of the organic compounds contained in liquid waste produced by the tofu industry. In aquatic ecosystems, excessive amount of nitrogen can lead to eutrophication and increase the amount of ammonia, nitrate and nitrite which are poisonous to humans, livestock and wildlife. In order to deal with the issues, photo-catalyst technology is employed to process the organic liquid waste by converting themintoCO_2 and water which are relatively safer. Throughout the process, it requires a medium like resin immobilized photocatalyst-ZnO (RIP-ZnO) to absorb the pollutants. Based on the aforementioned background, this study aims to analyze the impact of RIP-ZnO capacity in reducing the total Nitrogen parameter. The analysis of total Ninthisstudy was conducted by using the Kjeldahl method consisting of three processes, namely destruction, distillation and titration. The research began with the process of making reactor and RIP-ZnO. Subsequently, once the total N concentration is known, the process of resin capacity calculation is continued. As a result, the research findings indicate that the highest resin capacity of 1.14542 reduces the total Nby 33%, while the lowest one of 0.00012 decreases it by 59%. In other words, the resin capacity has an impact on the percentage of total N removal. In conclusion, the lower the resin capacity is, the higher the removal percentage is, and vice versa.
