Abstract

Research on projections of greenhouse gas emissions has been carried out in the sector of transportation energy for official vehicles in Mulawarman University. The study used secondary data of fuel use of the official vehicles from 2015 until 2019 to determine the greenhouse gas emissions dominated by CO2 , CH 4 dan N2 O. The trend of the obtained greenhous gas emissions was used to predict the greenhouse gas emissions in the range of 2020 and 2030. The projections of CO 2 emissions, CH 4 emissions, and N2 O emissions, in the years, respectively, are 427,281 tons of CO2 -eq, 5,697 tons of CO2 -eq, and 5,228 tons of CO2 -eq. The calculation revealed that in the next eleven years the projection of the greenhous gas emissions due to the use of official vehicle fuel in Mulawarman University will reduce continuously.

Abstract

Heavy metal pollution is still a serious problem today. One method that can be used to remove heavy metal content from water is the adsorption method. In the adsorption method, the choice of adsorbent is very important to optimize the adsorption process. One of the materials that can be used as an adsorbent is tea waste. Tea waste contains cellulose, which can be used to bind heavy metal ions. This research was conducted to synthesize adsorbents using tea waste and then test their ability to adsorb lead ions. The adsorbent synthesis process is divided into several stages, namely washing, drying, refining, soaking in HCl solution, and drying again. The results of the adsorption tests conducted found that the tea waste adsorbent could remove 99% of the lead metal ion content in the water. The conclusion from these results is that the synthesis process has succeeded in making tea waste adsorbent that can adsorb lead ions in water.
