For regulatory purposes, air pollution has been reduced to management of air quality control regions (AQCR), by inventorying pollution sources and identifying the receptors significantly affected. However, beyond being source-dependent, particulate matter can be physically and chemically altered by factors and elements of climate during transport, as they act as local environmental constraints, indirectly modulating the adverse effects of particles on the environment and human health. This case study, at an industrial site in a Brazilian coastal city – Joinville, combines different methodologies to integrate atmospheric dynamics in a strategic risk assessment approach whereby the influence of different wind regimes on environmental and health risks of exposure to PM2.5-bound components, are analysed. Although Joinville AQCR has been prone to stagnation/recirculation events, distinctly different horizontal wind circulation patterns indicate two airsheds within the region. The two sampling sites mirrored these two conditions and as a result we report different PM2.5 mass concentrations, chemical profiles, geo-accumulation, and ecological and human health risks. In addition, feedback mechanisms between the airsheds seem to aggravate the air quality and its effects even under good ventilation conditions. Recognizably, the risks associated with Co, Pb, Ni, Mn, and Zn loadings were extremely high for the environment as well as being the main contributors to elevated non-carcinogenic risks. Meanwhile, higher carcinogenic risks occurred during stagnation/recirculation conditions, with Cr as the major threat. These results highlight the importance of integrating local airshed characteristics into the risk assessment of PM2.5-bound components since they can aggravate air pollution leading to different risks at a granular scale. This new approach to risk assessment can be employed in any city's longer-term development plan since it provides public authorities with a strategic

Maninjau Lake can be found in West Sumatra province, specifically in the Tanjung Raya District of the Agam Regency. The Government and the nearsocieties utilize the lake catchment area aimed at agriculture, refreshment, settlement and floating net cages. Increased anthropogenic activity can affect the quality of the lake. This investigation’s goal is to assess Lake Maninjau’s water quality using the Pollution Index (PI) and the Storage and Retrieval (STORET) method. The research was showed at five sampling stations in the Maninjau Lake area from November 2021. The water quality in Maninjau Lake is classified as moderately polluted by the STORET method. Nonetheless, the Maninjau Lake’s water quality falls under different categories according to the PI. From Good condition to Moderately polluted is the range for Class I (in use as a water source for drinking). Lightly to Moderately polluted is Class II (outdoor recreation assets and facilities, fishery, livestock farming, and agricultural uses). Class III, on the other hand (meant for breeding freshwater fish, raising livestock, and watering crops) and Class IV irrigation systems are categorized as Good condition and lightly polluted, respectively.

Green campus is a concept, which integrates environmental science into policy, management and activities of the college. Green campus is also the implementation of the integration of environmental science in all aspects of management and sustainable development practices. Therefore, the standards for referral and encouragement to management in developing a green campus program are needed, one of which is UI GreenMetric. The purpose of this study are to determine how the program of UI GreenMetric is implemented at Diponegoro University and to provide recommendations in the category or indicator that has not been fulfilled. Optimizing the implementation of UI GreenMetric can be used as a further reference in the development of green campus concept in Indonesia. This study uses data in the form of a literature study of standards and guidelines used by UI GreenMetric which are considered in accordance with the strategy of increasing effectiveness in implementing green campus. The results showed the value obtained by Diponegoro University in the UI GreenMetric World University Rankings standards. © The Authors, published by EDP sciences, 2019.

The herbal, tofu and fertilizer industries contribute considerable waste. Unprocessed waste disposal can cause environmental pollution. The waste contains chemical oxygen demands (COD), and organic substances can be degraded by Advanced Oxidation Processes (AOPs) degradation method. The process of AOPs in this study used a combination of UV rays and ozone to produce hydroxyl radicals. This study was aimed to investigate the effect of UV, Ozone and UV-Ozone methods on COD degradation of herbal waste, tofu, and fertilizer. The result showed that the optimum degradation was obtained at experiment by using UV/ozone method. The COD degradation at tofu wastewater was from 1308 to 942 ppm, herbal wastewater was from 1011 to 414 ppm, and fertilizer wastewater was from 510 to 89 ppm by the use of 4 hours UV-Ozone method. © Published under licence by IOP Publishing Ltd.

Hard water is one of crucial problems in the world due to its pollutant parameters. Adsorption is a promising method for treating hard water because of its benefits such as low-cost, easy to use, acceptable, and easy to maintenance. In this study, we utilized zeolite functionalized with silicon/aluminum (Ze-Si/Al) as adsorbent materials for hard water treatment. Ten different ratios of Si/Al were added into zeolite by modifying the solid waste source concentration (pumice and cans). The optimum sample was then further tested with different parameters including contact time, dye concentration, and isotherm models. The zeolite-Si/Al adsorbent was characterized by Scanning Electron Microscope (SEM), X-Ray Diffraction (XRD), and X-Ray Fluorescence (XRF). Results of this study have showed that the best functionalized zeolite was that with Si/Al ratio 0.67, which has higher sorption ability. In contact time test, the equilibrium was reached after 300 min. This study also informed that the concentration of dyes will give impact on removal of pollutant parameters. Isotherm model of Ze-Si/Al fitted with Langmuir method. This study also discussed the potential development and future research direction. Thus, this study is a crucial report to develop the information about waste utilization as source of Si/Al to increasing quality of zeolite. © 2023 Elsevier B.V.

Energy balance analysis study for the production process of biodiesel needs to be done to find out whether a production process of biodiesel activity has a surplus energy or minus energy. This study aims to analyse the balance of energy of the plantation of palm, production of palm oil, and production process units of biodiesel with the life cycle assessment in Banyuasin-Indonesia. The results of this study indicate that the largest energy input in the plantation of palm, production of palm oil, and production process units of biodiesel sequentially is the use of urea as N-fertilizer, electricity, and methanol. The value of NEB and NER in the production process of palm biodiesel sequentially is 5871 MJ and 1.17. Finally, the production process of palm biodiesel in Banyuasin area has a positive energy balance. The activity of production of palm biodiesel is proper to operate because it produces an energy surplus. © The Authors, published by EDP sciences, 2019.

Disposal of Lapindo mud which carries nutrients and other dissolved organic matter into the Porong estuary, can cause the death of aquatic organisms due to high contamination and disturbance of aquatic ecosystems. The presence of phytoplankton can explain the current condition of the Porong Estuary. The purpose of this study was to report the water quality and plankton composition of the Porong estuary. The method used in this study is a descriptive survey method. Determination of sampling points using the appropriate sampling method at three stations. The research variables observed included water quality parameters such as temperature, total dissolved solids (TDS), total suspended solids (TSS), total organic matter (TOM), pH, dissolved oxygen (DO), carbon dioxide (CO2), biological oxygen demand (BOD), nitrate, ammonia, orthophosphate, salinity and observations of phytoplankton in water bodies. The water quality values at stations 1, 2, and 3 respectively for TSS, pH, DO, BOD, TOM, nitrate, ammonia, orthophosphate shows a less than optimal value. Water conditions based on plankton abundance 24,678 cells/mL, 44,904 cells/mL, 18,312 cells/mL were eutrophic. The average of water quality parameters classified as less than optimal. Relatively, station 1 is the station with the best conditions between stations 2 and 3.
