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.

The contribution to the increase in CO2 emissions can come from all the activities of construction workers who use energy such as the procurement of building materials, the use of transportation fuels, the activity of using electricity, and the activity of using LPG. The carbon footprint is a measure of the total amount of carbon dioxide (CO2) emissions originating from activities or the accumulation of daily activities. carbon footprint calculation using the IPCC 2006 method. The carbon footprint calculation results obtained from the development activities of the Miftahun Najah Islamic boarding school building in the procurement of building materials resulted in a carbon footprint of 2.8417 tons. CO2-eq, trucking activities, construction workers produced 550.7 tons. CO2-eq, the activity of using electricity produces a carbon footprint of 39.403 ton.CO2-eq/kWh, and the activity of using LPG produces a carbon footprint of 0.11 ton.CO2-eq. The purpose of measuring the quality of Carbon Dioxide (CO2) is to determine the concentration of CO2 during the development of buildings at the Miftahun Najah Islamic Boarding School.
