Polyethylene terephthalate (PET) is a polyester which is widely used as a container or packaging material, especially mineral water and soft drinks. Recycling is necessary to overcome the post-consumer PET waste PET difficult because degraded naturally. Chemical recycling is an appropriate method for depolymerisation. Glycolysis is the method that is often used as the process was easy. Optimization parameters of glycolysis on the rate of reaction in the efforts to improve the products of glycolysis has been done as the use of catalysts. Metal acetate catalysts such as zinc acetate is a catalyst which shows good activity in the reactions of glycolysis, but the catalyst is non-biodegradable and toxic. The metal oxide catalysts are also many well developed but these catalysts are toxic, corrosive and can cause severe pollution. More environmentally friendly catalysts such as sodium salt today began much developed to minimize the impact to the environment. Keywords: depolimeritation, glycolysis, polyethylene terephthalate (PET), catalyst, bis (hydroxyethylene) terephthalate (BHET)

Seawater intrusion causes groundwater in coastal areas to be brackish, so it requires special processing to remove salt levels in raw water so that the water becomestasteless. In addition to salinity, the presence of bacteria in water can cause disease if consumed without proper processing. Brackish water treatment called desalination can be done by ion exchange using an activated carbon filter. The purpose of this study was to determine the efficiency of the performance of brackish water processing filters in setting aside water quality parameters in the form of: coli bacteria and total bacteria expressed in the Total Plate Count (TPC). The filtration reactor is made using filter media in the form of activated charcoal (20 cm), silica sand (15 cm), zeolite (15 cm), and gravel (10 cm). laying the reactor upright and tilted 45 degrees. The results showed that the reactor filter was effective in reducing Coliform bacteria and total bacteria in raw water up to 100% and 97%, respectively, although it did not meet drinking water quality standards PERMENKES No.492/Menkes/Per/IV/2010. Both reactor variations have performance effectiveness that is not significantly different in processing raw water, but overall reactors with upright variations have better performance. Keywords: Active Carbon Filtration, Coliform, Total Plate Count.
