Abstract

Transportation is one of the anthropogenic activities that emit CO2. Its existence is essential for human mobilization, which causes the need for mitigation and solutions that can support the continuity of activities while minimizing the impact of emissions. In this case, the green belt of Jalan Jagir Wonokromo contains a mixture of road protection and CO2-absorbing vegetation that can reduce emissions. For this reason, a study was conducted to determine the CO2 absorption potential of green belt vegetation to provide information and a reference for optimizing green open space. The research was conducted using a quantitative descriptive method, which included measuring road ambient CO2 concentrations, calculating vehicle volume, measuring breast height diameter as a biomass component, and researching correcting CO2 absorption by vegetation. According to the research results, the average ambient concentration of CO2 on roads is 785 mg/m3. The transport CO2 concentration was calculated using a Tier II approach and yielded a value of 186.87 kg/hour, contributing 79% to the ambient CO2 concentration.Furthermore, a box model is used to analyze the concentration of CO2 that will be absorbed by vegetation, resulting in 103.47 tons per year. Meanwhile, the ability to absorb CO2 from vegetation is 152.74 tons/year after being corrected by a pilot-scale study that considers vegetation's age and physiological factors. All emissions on Jalan Jagir Wonokromo can still be absorbed by vegetation, but optimization needs to be done in the form of intensification, extensification, and mitigation.

Abstract

Effective and efficient water treatment is needed to improve water quality. The content of iron (Fe) and manganese (Mn) compounds in water is a major problem that can affect health and interfere with human activities. One of the steps that can be taken to degrade manganese is oxidation using aeration. In this study, variations in the diameter of venturi aerators were used to determine the performance of venturi aeration in water treatment. The variation in diameter was set at 12mm, 10mm and 8mm sizes. Based on the results of the study, dissolved oxygen levels have increased over time. The highest increase in dissolved oxygen content was achieved with the 12 mm diameter variation with dissolved oxygen levels reaching 7.8 mg/litre within 60 minutes. a significant reduction in iron content of 92% with an iron content of less than 0.0567 mg/litre. The largest percentage decrease in manganese content occurred with the variation of the aerator vent hole diameter of 12 mm, which was 54% with an aeration time of 15 minutes. There is a fluctuation in the decrease in manganese content caused by the more difficult to oxidise properties of manganese.

Abstract

The Kali Surabaya River is one of Indonesia's rivers impacted by pollution from industrial and domestic activities. Conventional water pollution analysis generally relies on physicochemical parameters and often overlooks biological factors. This study aims to analyze phytoplankton biological indices as bioindicators of water quality and integrate them with the results of the Pollution Index (PI). Water samples were collected using purposive sampling from four stations for the analysis of physicochemical parameters and phytoplankton identification using a 40 µm plankton net. The obtained data were analyzed by calculating the phytoplankton diversity index and the Pollution Index (PI). During the two-week research period, the phytoplankton community structure was dominated by Scenedesmus sp. (22.92%), Nitzschia sp. (12.76%), and Merismopedia sp. (10.75%), indicating organic pollution and eutrophication in the Kali Surabaya River. The PI results classified the river as slightly polluted (1.8 – 4.935). This study concludes that the integration of phytoplankton bioindicators with the pollution index analysis is effective in indicating pollution status and condition.
