Tofu liquid waste comes from the washing process, boiling, and printing on tofu production. Tofu liquid waste is usually directly discharged into rivers or sewers which can have a negative impact on the environment. Tofu wastewater treatment with activated charcoal adsorption methods can reduce the concentration of pollutants contained in the waste. This research was conducted to determine the effect of variations in stirring speed in the removal of COD and TSS levels in tofu liquid waste. The adsorbent used in this study was activated charcoal from the skin of jengkol (Pithecellobium lobatum) carbonized at 350ºC which was then activated using 1M HCL. The adsorption process in this study used a mass of 2 g of activated charcoal; 4 g, 6 g and 8 g and stirring speed 60 rpm and 120 rpm. The initial concentrations of COD and TSS were 5140 mg/L and 605 mg/L. The results of the research that have been carried out show that the stirring speed and mass of the adsorbent affect the levels of COD and TSS as well as the effectiveness and adsorption capacity. A significant decrease in COD and TSS levels occurred in the treatment using 8 g of activated charcoal and a stirring speed of 120 rpm. The COD value obtained was 1137 mg/L, TSS was 103 mg/L and the efficiency value obtained was COD of 77.88% and TSS of 82.98%.

One solution for domestic waste treatment is the operation of a communal IPAL (WWTP, Wastewater Treatment Plant). This is in accordance with SDG's (Sustainable Development Goals), national and regional policies related to sustainable sanitation management. In Banda Aceh, the Sanimas (Community sanitation) program has been and is being implemented in 40 gampongs (villages) which are classified as slum areas. This study aims to determine the results of the effluent processing of the IPAL system (pH, BOD, COD, TSS, ammonia, Total Coliform, Oil/Fat parameters) to see whether the IPAL system that has been built is operating properly. There were five IPALs studied, namely in Gampong Peunayong (Dusun Cendrawasih), Gampong Tibang (Dusun Tgk. Meurah, Dusun Tgk Meulinje, Dusun Tengku Meulagu), and Gampong Panteriek (Dusun Jeumpa). The results of the effluent wastewater test showed that in all WWTPs, the BOD and COD parameters still exceeded the wastewater quality standards, and in one WWTP, the total Coliform parameter was >1,000/100 ml (quality standard >3,000/100 ml).

This study aims to identify the water quality of the Krueng Brayeun River as one of the potential surface waters to meet the needs for the development of a Drinking Water Supply System (SPAM) in Banda Aceh City and Aceh Besar District. Water samples were taken at five locations around the planned intake, namely two points before the planned intake and three points after the planned intake. Laboratory tests were carried out on physical, chemical, and biological parameters. Based on the test results, it is possible to use the proposed intake location as a source of raw water for PP RI No. 22 of 2021 class I. There is no possibility of pollution at the site of the proposed intake, and water-related activities that are carried out close to bends do not have an impact on the river of quality Kr. Brayeun. Recommendations for securing raw water sources are needed so that the utilization of Krueng Brayeun River water does not interfere with the PDAM's processing process.

Any laundry operation will discharge the waste water directly to the water surface, which can lead to pollution in the water. One method that can be used to treat laundry wastewater is a photocatalytic method with TiO2 (Titanium Dioxide) as an UV-assisted catalyst that is combined with a strong H2O2 oxidizer to produce OH (hydroxyl radical) to oxidize pollutants. The study aims to determine the differences in pH, TSS, BOD, COD, and Phosphate separation values with combination of TiO2 and H2O2 doses with variations in UV exposure time for 30, 60, and 90 minutes. A good quality TSS level obtained in the 60th minute with a dose of 1 g TiO2 and in combination with 10 ml H2O2 can reduce TSS levels by 20 mg/l from the initial TSS with a residual weight of 180 mg/L. A decrease in the quality COD level at a 90 minute clearance time with a dosage of 1 gr TiO2, in a combination of 10 ml H2O2, can reduce the COD levels by 32.5 mg/ l from the original COD value of 89.1 mg/l. A reduction in the phosphate level achieved at the cleaning time of 30 minutes at a combined dose of 4 gr TiO2 in a 40 ml combination, can lower the phosphatic level by 0.05 mg /l from the starting value of 5.61 mg/l and already meet the quality standard of laundry waste water.

The area of Bundaran BNI 46 Simpang Jam in Banda Aceh is an area that is often crowded with motorized vehicles. Motor vehicles produce CO as their exhaust gas. Excessive levels of CO in the air can harm human health. CO can turn into CO2 in the air. Overrated CO2 in the environment can cause greenhouse gas effects and global warming. CO2 can be absorbed by plants for their use in the photosynthesis process. The absorption of CO2 for each vegetation is different starting from very high to low. This research is a quantitative study to determine the total absorption capacity of vegetation in the area of Bundaran BNI 46 Simpang Jam on CO2 emissions which was done on April 2020. Calculating vehicle emissions and vegetation absorption using manual counts method at peak hours and calculations based on literature. From the research, it is known that the total number of vehicles passing through the area is 3250 motorized vehicles/hour with total emissions of 7,343,017,347 Kg/year. The total absorption capacity of 351 vegetation in that area is 614,410.30 kg/year. Accordingly, the area's vegetation is unable to absorb CO2 emissions optimally. To optimize CO2 absorption, vegetation replacement must be carried out. The tree combinations that can be selected to absorb all of the area's CO2 emissions are 320 Trembesi, 326 Kasia, 340 Glondokan, 305 Kenanga and 215 Beringin.

Noise pollution is a major concern in companies. The utilization of machines to support a production activity in factories or indutries can cause unwanted noise. PLTD Rema is one of diesel power plant companies in Gayo Lues regency which has been running for 18 years. Diesel engines at PLTD Rema will certainly cause noise that disrupt the workers’ hearing. The aims of this study are to identify the noise level, map noise, and examine workers' insights of noise in the area of PLTD Rema. This study shows that the highest noise level of 91.3 dBA lies at sampling point 1. Meanwhile, the lowest value of noise level of 68 dBA lies at sampling point 12. If all of the results of the noise level evaluation at 12 sampling points are evaluated with the Regulation of the Minister of Manpower and Transmigration No. 13 of 2011, the noise levels acquired are unthreatening for all PLTD Rema’s empolyees, except for the area of diesel engines. Moreover, the mapping of noise levels using urfer 13 software consists of 5 different colours (green, blue, red, yellow, and orange). The last one, the workers' perception towards noise has been accepted or H0. Therefore, the noise produced at PLTD Rema has no impact to thier workers’ performance.
