Abstract

The Gembolo River is ± 14-15 m wide with a depth of 1 to 2 m and flows towards the north (downstream). With the movement of river water flow, there will be an influence in the direction of the movement of the river flow. The distribution of pollutant parameters due to the movement of the river flow will result in a decrease in pollutant concentrations along with the further movement of the water flow of the water body (self-purification). This study aims to determine the simulation of decreasing the concentration of key parameters from the resulting treated wastewater, including BOD, COD, TSS, ammonia (NH4) and total coliform in the Gembolo River, Mojokerto. The simulation itself was carried out for 15 days taking into account seasonal conditions (dry season and rainy season) with the help of Mike 21 software. The results of the simulation along the Gembolo River during the dry season and rainy season have different results, namely a BOD of 1.02 mg /l and 0.980 mg/l, COD of 1.4 mg/l and 1.23 mg/l,and ammonia (NH4) of 0.386 mg/l and 0.381 mg/l. From the simulation, when compared with the required quality standard, it is still below the quality standard.

Abstract

PT X is a company engaged in the bottled water and soft drink industry where the production machines that are operated cause noise pollution which pollutes the environment around industrial settlements. Based on the known environmental impacts from the operational activities of one of the bottled water and soft drink industries in the Pasuruan area, noise levels, noise distribution, as well as solutions and anticipatory actions as a result of noise disturbances caused by industrial activities can be identified. In an effort to determine the impact of noise on the area around the business location, mapping is carried out using Surfer v16.0 software so that the contour map and the distribution of areas affected by the spread of industrial noise pollution are known. The analytical method used is to collect data in the production area or space as well as the area around industrial activities. The largest noise measurement results were in the production area of 83,9 dB(A) and the closest residential area II had the smallest noise level of 23,7 dB(A) as measured using a Sound Level Meter (SLM).

Abstract

A hotel B building that has been operating in the city of Surabaya generates domestic waste from lodging activities by hotel visitors and employees, restaurants and kitchens. The waste will be used for washing and watering in the Green Open Space which is at the back of the hotel with a total waste water produced of 7.52 m3/day. The resulting wastewater contains Ammonia, BOD, COD, Oil and Fat and coliform which exceeds the standard limits for the quality of wastewater so that it must be managed first before being used for watering plants in accordance with Regulation of the Minister of Environment and Forestry No. 68 of 2016 concerning Domestic Wastewater Quality Standards. The activity site has a grease trap, biofilter and WWTP unit which will be used for wastewater treatment to meet quality standards. The Green Open Space area is 10.5 m2 which will be used for the utilization of treated wastewater. The total volume of outlet water to be used for watering is 3.1 m3/day. Utilization of water can save PDAM water usage to support the production process or maintenance activities (watering the plants) around activity and/or business locations.

Abstract

The industrial world is growing rapidly over time, including PT J which is engaged in animal feed rations and meat processing. However, apart from producing products, the industry also produces waste products or emissions from supporting activities for the animal feed ration industry and meat processing. It is a challenge in itself to overcome so that the emissions produced do not exceed the environmental capacity around the PT J industrial area, as well as the suitability of the resulting emission value with the applicable regulations. The emission distribution modeling map is done by processing the emission data from the Steam Boiler unit and generator and then running the data in the AERMOD software. The results of running data using AERMOD show that the highest concentrations of emission distribution for parameters NOx and particulates are at a distance of 200-300 m with respective values of 38.3 µg/m3, and 10.4 µg/m3. Regarding to Appendix VII PP. No. 22 of 2021 concerning the Implementation of Environmental Protection and Management, it can be concluded that the environmental capacity for emission discharges from PT J's industrial location is still sufficient.

Abstract

The current development factor is that restaurants, bars and night clubs are increasingly developing in big cities, one of which is the city of Surabaya. W's business activities, which are engaged in the restaurant, bar and nightclub business in Surabaya, produce domestic wastewater originating from kitchen, sink, dish washing and bathroom activities. The volume of clean water required to meet these needs is 7.86 m3/day at peak hours. The waste water produced from this activity is 5.28 m3/day and will be managed and used for flushing toilets. The levels of contaminants contained in wastewater such as COD, BOD, TSS and oil and grease must be adjusted to the wastewater quality standards listed in PERMEN LHK Number P.68 of 2016. Wastewater is treated using grease trap and biofilter technology to obtain outlet water. that meets water quality standards. The final water outlet has a water discharge of 3.37 m3/day while the water requirement for flushing the toilet is 2.38 m3/day. Therefore, the remaining unused outlet water will be stored in a storage tank and will later be handed over to a third party. Utilizing the results of wastewater treatment as flushing toilets can save the use of clean water for domestic clean water needs

Abstract

One of the important aspects in mining activities is the drainage system. A good drainage system can prevent flooding, erosion, landslides, and water pollution caused by mining. The drainage system applied in the clay mining site consists of making drainage channels at the bottom of the mining benches. This is intended to capture the mine runoff water. The mine floor is sloped towards the drainage channel. Data collection is carried out, which includes data on location, area, and slope of the mining area, rainfall, runoff coefficient, and then calculations are performed using the Manning equation to obtain the channel dimensions. The planned open channel dimensions have a channel base width = 0.908 m, flow depth = 0.79 m, wet cross-sectional area = 1.07 m, wet perimeter = 1.943 m, hydraulic radius = 0.39 m, water surface width = 1.824 m, and freeboard = 0.197 m. The construction of the drainage channel is intended so that the water on the mine floor can flow directly to the drainage channel, thus not disturbing the mining activities

Abstract

Domestic waste produced by one of the chicken cutting industries, PT X, in the Jombang region, East Java, has not been properly treated. Domestic waste, commonly known as greywater, is wastewater originating from kitchen activities, toilets, sinks, and so on, carried out by the workers. If this wastewater is directly discharged into the environment without prior treatment, it can cause pollution and have adverse effects on aquatic life. One of the efforts to manage PT X's domestic waste is by using the Anaerobic Baffle Reactor (ABR) unit. The selection of the ABR unit is based on the treatment system at PT X's wastewater treatment plant (IPAL). In this IPAL, there is a sedimentation process and degradation of organic material by anaerobic bacteria, which can minimize the land use for domestic wastewater treatment. The aim of this research is to determine the efficiency in reducing parameters present in PT X's domestic wastewater, namely COD, BOD, and TSS. This study is expected to provide an alternative for treating domestic waste at PT X so that the discharged waste does not pollute the surrounding factory environment.

Abstract

The industrial activities of chicken slaughterhouse and meat processing by PT X generate waste that needs to be treated through a Wastewater Treatment Plant (WWTP) during the operational processes. However, the WWTP of PT X indicates a need for improvement in wastewater treatment performance to optimize the reduction of pollutant parameters in the wastewater generated by PT X’s industrial operations. The performance evaluation of PT X’s WWTP is conducted by examining technical aspects, ensuring that the WWTP can operate optimally, and the effluent wastewater meets the standard quality requirements. Therefore, the quality of the effluent can be assured to protect the sustainability of natural resources in the surrounding area, especially the water resources in the vicinity of PT X’s industrial activities. Based on the technical analysis results, the optimization of treatment standards at PT X’s Wastewater Treatment Plant (WWTP) is planned by adding an Biofilter Aeration unit to ensure that the quality of the generated waste meets the standards.
