Agricultural activities cannot be separated from the use of pesticides to control plant-disturbing organisms. The mercury (Hg) content in pesticides cannot be naturally degraded on agricultural land, so it will be carried off by run-off into the waters. Pesticide’s run-off from agricultural activity along the Sumur Beremas River has an effect in increasing mercury concentrations in the river. This study aims to analyze the effect of pesticide use on mercury concentrations in the Sumur Beremas River and to analyze the capacity of river pollution loads. The effect of pesticide on mercury concentrations was analyzed using Pearson correlation. The capacity of Sumur Beremas River's pollution loads against mercury was analyzed using mass balance method. The results showed that the use of pesticides had a significant effect on the increase in mercury concentrations in river water. The greatest correlation value occurs in downstream of irrigation, namely 0.977, which indicates the high run-off that occurs from agricultural area to the irrigation flow. The concentration of mercury based on the analysis of river pollution loads is 0.00242 ppm, exceeding the standard PP no. 82 of 2001 Class II, 0.002 ppm, which indicates that Sumur Beremas River is no longer able to accommodate the load of mercury pollution.

The planning of sewerage system in Telanaipura subdistrict is an urgent program. This is because there are many puddles of water on the area that can interfere the the community. Therefore we need a domestic sewerage system that carried by by pipeline form the tank to the building septic processing (small bore sewer). For domestic wastewater treatment used sump wells equipped with pumps, initial sedimentation pond, stabilization pond, and collector pond. It is expected that delivery system and treatment of domestic waste water in the Telanaipura can reduce sanitation problems and the can realize a healthy region, comfortable and livable.Keyword : Telanaipura, small bore sewer, sewerage

Tofu factory in the district Dendang factory on an industrial scale is generally managed the household. In one day this factory uses raw materials such as soybeans (Grylin Spp) of 50 kg and the results obtained only marketed around the District Dendang. The volume of waste generated over 2.25 to 5 m³ / day. Mr. Ahmad Yamin’s tofu factory is one of the largest factories in the district Dendang, Tanjung Jabung Timur has characteristics of pH wastewater, TSS, NH3-N, BOD, COD, NO3, NO2, sequence 5, 34, 329 mg / l, 03:49 mg / l, 581 mg / l, 1228 mg / l, 1.3629 mg / l, 1.3771 mg / l. Some wastewater parameters have been tested exceed the quality standards appropriate to KEPMENLH NO 51, 1995. Generally, the wastewater can pollute the environment out either physically, chemically and biologically. It is necessary to develop wastewater treatment technologies that are simple, low cost, easy operation and has a high processing efficiency of pollutants. One alternative biofilter wastewater using anaerobic aerobic reactor is developed with the principles of microbial growth and attached to the filter media and form a layer biofilm. Data collection methods used are field surveys, documentation, literature review and alaisis laboratory to determine the characteristics of water limbah.Hasil waste discharge planning calculation for 25 (twenty five) years is 38.18 m3 / dayKey word : Liquid Waste Know, anaerobic-aerobic biofilter.

This research aims to determine the magnitude of the CO concentration in the ambient air at the Y T-junction Simpang Rimbo, Jambi City using a CO meter. Observations were carried out for 3 days (Sunday, Monday and Tuesday). Sundays and Mondays are held at 2 different times, namely the afternoon and evening. 1 day observation on Tuesday with 4 different times, namely Morning, Afternoon, Afternoon and Night. Each observation time at 1 point is carried out for 60 minutes. The results of the 3 day study showed that the highest CO concentration occurred on Tuesday during the day, namely 279,424.4 ??/??3, the lowest CO concentration occurred on Sunday at night, amounting to 63,426.27 ??/??3. Meanwhile, observations for 1 day on Tuesday showed that the highest CO concentration occurred in the afternoon at 9.0056 ??/??3. The CO concentration was higher when measuring for 3 days, this was due to the influence of time and the reduction in vehicles passing the observation point on Tuesday 6 February 2024.

The aim of this research was to determine the removal of Total Suspended Solids and fatty oils using the grease trap and filtration methods. Based on the results of experiments that have been carried out, the removal efficiency of Total Suspended Solid at various residence times reached 99.09% (12 hours), 97.89% (24 hours), 98.65% (36 hours), 98.89% (48 hours), 99.18% (60 hours), and 99.3% (72 hours). Fatty oil removal over a period of 12 to 72 hours reached 99.99%. The use of grease traps and filters with biochar rubber and sand media shows that this treatment has proven effective in reducing levels of Total Suspended Solids and fatty oils to meet domestic wastewater quality standards.
