Abstract

Growing of Eichhornia crassipes (Mart), Solms) depend on environmental factors e.g. material organics, sun lighting, water depth, salinity, and pH . However this plant have ability to absorb organic element, organic compound, and other chemical element that can be able to use as biological absorber in waste water treatment.The research is to know the effect of contact time and age of  Eichhornia crassipes (Mart), Solms) toward of ammonia concentration in hospital waste water.The method of this research is Experimental design with One Group Pre Test Post Test Design. The outcome of the research have shown that average ammonia concentration decrease with young plants is 62,17 % at 2 days contact time, 87,1 % at 4 days contact time, and 94,3 % at 6 days contact time. With old plant  ammonia concentration decrease 79,35 % at 2 days contac time, 97,61 at 4 days contact ime, and 98,4 % at 6 days contact time. From the result can be conclude that plant of Eichhornia crassipes (Mart), Solms) had significant ablility to descrease of ammonia concentration in waste water.

Abstract

In  general,  waste  management  in  most  of  City  in  Indonesia  still  boundary  on collecting, transporting  and  dumping.  Solid  waste  are    collected,  transported  and  pulled  up  in landfill without any treatment. Needed a new paradigm that landfill is not a final estuary of city waste but place management of city waste. One of the problem faced is amount arise of organics city waste. Starting from this situation hence needed handling to arising organic waste. Composting represent  one  of  the  alternative  in  the  effort    to  reduce  the  amount  of  organics city  waste through  the  make  up  of  value  utilize  waste  become  worthwhile  compost  as fertilizer.  Natural composting of organics waste took a time to process. Effective microorganism (EM4) applicated in  organics  waste  composting  in  landfill  is  used  to  speed  up  compost  decomposition and improve the compost quality. Composting use all kinds of city waste that enter to the landfill, like residue of vegetables, fruits, leaves and sawmill waste. Composting city waste wrap up addition material that  is sawdust and  cow  manure. At this research, compost  variation  include natural control variation, organic waste and EM4, organic waste : sawdust and EM4 with comparation 7:3; 1:2; 5:7; 5:4 and 7:6. Organic waste:  cow manure and EM4 with comparition 1:2; 2:5; 6:5 and 7:6. Result of this research indicate that the overall compost variation has fulfilled standard of  quality  matured  compost  according to  SNI  19-7030-2004t.  Compost  with  EM4  has relative good  quality  than  natural  compost.  Besides,  overall  of  compost  variation  have  fulfilled hara standard of crop requirements, low cost of producing and yield high level of city waste reducing. Compost  variation of 7 organic city waste : 3 sawdust represent  most applicable composition compost  at  Boyolali  landfill  with  C-organic  24,52  %,  N-total  1,72  %,  Ratio  C/N 14,25,  P-total 1,20 %, K-total 1,66 %, Temperature 27,70 0C and pH 7,30 also compost level reduction 61,6 %.

Abstract

Every industry has a potential to pruduce waste from its production processes. Waste defined as  unused material  coming  from  the  production  activity.  Type  of  industrial  waste  may  vary depend on production activity, such as raw material, type  of processes, including type of raw material used, machinary, which will influence the characteristic of waste itself. Pharmaceutical industry, within their production activity will produce waste which may be potential for harming the environment. The waste may in form of toxic or non toxic chemical substances in both solid or liquid waste. Most of the waste characterize as hazardous waste and need further treatment due to avoid environmental hazard. Hazardous waste from pharmaceutical industry are in form of sludge from waste water treatment plant (WWTP), rejected material and also used container.
