Utilization of an environmentally sound drainage system or eco-drainage is a drainage management system in a sustainable manner by observing the carrying capacity of nature or environmental conditions so that solutions to problems caused by runoff of rainwater and wastewater can be created and can reduce the pollutant parameters of water that enters the final disposal. The initial condition of …
Wastewater is water that has been contaminated by organic and inorganic substances generated by human activities or industrial processes. Improper management of wastewater can have negative impacts on the environment. One approach to address this is by treating greywater through a constructed wetland system. A constructed wetland system is a wastewater treatment system that utilizes aquatic pla…
The application of an environmentally sound drainage system or eco-drainage is a sustainable drainage management system by observing the carrying capacity of nature or environmental conditions so that solutions to problems caused by rainwater and wastewater runoff will be created and can reduce water pollutant parameters that enter into final disposal. The initial condition of the rubber waste …
The utilisation of fine coal waste is still limited, even though its availability is very abundant in the mining industry. This study utilises fine coal by converting it into syngas through catalytic gasification. The gasification process was carried out at a temperature range of 350–550°C for 10–50 minutes using natural zeolite as a catalyst. The syngas composition and quality parameters …
Laboratory wastewater should not be discharged directly into the environment without further treatment. That can cause pollution to the environment, whose impact is also felt by living things around it. Materials contained in laboratory wastewater are classified as hazardous and toxic waste materials (B3) that contain organic and inorganic materials such as Cd, Pb, Cu, Hg, Cr, Zn, Fe, and other…
Production activities in the oil and gas industry can cause environmental pollution, one of which is soil pollution. Soil contamination is generally found in the refinery area caused by oil spills or pipe leaks, loading and unloading, and oil transportation. In this study, oil-contaminated soil is processed by extracting the oil contained in the ground using water. The treatment process was app…
While high production of palm oil improves the community’s economy, it has the potential to damage the environment because it produces wastewater containing quite a lot of residual oil. The wastewater caused by this production process flows into the cooling pond before it is further processed in aerobic and anaerobic ponds. The residual oil contained in the cooling pond can be collected and u…
Andesite mining activities, there is a processing process aimed at producing products that meet consumer or market demands but also produce waste that causes environmental problems. The waste from this processing is stone dust. This waste treatment process is called the Sand Plant. The results of waste treatment are used as a mixture of lightweight bricks. The average sludge content of the 5 sa…
The variety of activities carried out by the community in the Indralaya market causes the emergence of liquid waste problems. Greywater from Indralaya Market sourced from activities carried out in the wet stalls, which include fish stalls, chicken stalls, and meat stalls. Indralaya market greywater has a high pollutant concentration, so it needs to be processed further first discharged into riv…
