Abstract: because Java-Bali system is weak. The power system stability needs to be increasing the 500 kV transmission lines. The construction of the south transmission line, planned since 1996, has been hampered by land acquisition problems. Locals in Depok in West Java and in Klaten and Bantul, Central Java, have refused to make way for the power line. A simulation by using Etap Power Station shows phenomena occurred during the blackout on August 18th 2005 the northern transmission line capacity extremely high (EHV) 500 KV transmission line Saguling-Cibinong (middle transmission line) is the only interconnected transmission line to invert electrical power from power station in East Java to West Java and Jakarta. The interconnection network along the Saguling-Cibinong transmission line cannot handle additional load since it almost reach its capacity limit. Moreover it is not flexible enough to supply power to Jakarta. By adding the north transmission line Muaratawar-Cawang and Muaratawar-Cibinon

Author(s): RACHMAWATI APRIANI
Abstract: Acid mine drainage is an environmental pollutant waste arising from mining activities . Acid mine drainage ( AAT ) sulphida formed when certain minerals that exist in rocks exposed to conditions where there is water and oxygen ( as the main factor ) which causes the oxidation processes and produces water with acidic conditions . The purpose of this study is to apply the use of ceramic membranes in acid mine water treatment unit and improve the quality of the acid mine water to be safely discharged into the environment . In this study , acid mine water through the process of coagulation , filtration using a filter size of 5 lm , activated carbon and ceramic membrane . Varied parameters are operating pressure differential is 10.3 ; 15.3 ; 18.3 psi with operation time is 15 , 30 , 45 and 60 minutes . The results showed that the ceramic membrane made from clay , rice bran and iron powder with a composition of 87.5 % clay , 10 % rice bran and 2.5 % iron powder and clay composition of 77.5 %
