Palm fronds contain high cellulose, so it can be used as an alternative raw material for making pulp. The purpose of this study is to look at the potential of palm fronds as raw material for making pulp. The process of making pulp used in this study is the organosolv process, which is releasing palm frond fibers with a solution of acetic acid with hydrothermal pretreatment. This study observed the effect of cooking time and cooking solution volume on percent yield. The range of variables used in this study was cooking time of 125,150 and 175 minutes with concentrations of acetic acid cooking solution of 10 percent and 15 percent. The results of pulp quality were analyzed by comparing the results of the cold soda process to obtain physical properties. The best pulp was obtained at 30 minutes cooking time and 175 °C with a tensile value of 0.63 kN / m, tear 228.49 mN and brigthness 13.18.
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 % , 20 % rice bran and 2.5 % iron powder resulted in a decrease permeate flux and decrease the metal content such as Fe , Mn and Al .
