Abstract

Sludge from waste water treatment of electroplating industry contains hazardous waste. Before sludge is dumped to landfill it's need treatment to reduce hazard matter. One of general treatment is sludge stabilization by adding cement and sand to get concrete block. From these research shows that sand is playing important role in binding heavy metal in cement. The mixing between sand, cement and sludge I: I: 2 as per standard for landfill (PP. no 85, 1999) can stabilized sludge but can not reuse as a building material because still contains heavy metal.

Abstract

The Function of stabilization is to decrease leachate or chemical reaction which is potential to produce pollutant from waste. Three kinds of stabilization such as addition of the cement, lime and organic sludge had been done before. The result showed that the sludge can bind heavy metal. Analysis result showed that the decrease 'in presentation of heavy metal are Zn (79%), Cu (83,5 %), Fe (99,97 %), Mn (JOO %) and Cr (98,2 %). This experiment is continued to find the optimum amount of cement added to the sludge. The result showed that by addition of 5 % cement in textile sludge can hold the heavy metal.

Abstract

Pupuk organik adalah pupuk yang dibuat dengan menggunakan aktivitas rnikroorqanisma.Penelitian ini bertujuan untuk mendapatkan pupuk organik dengan kandungan hara makro tinggi memanfaatkan batuan fosfat dan limbah industri pengolahan kelapa sawit. Metoda penelitian adalah proses pengomposan limbah peternakan berupa koran dan darah, limbah kelapa sawit berupa cangkang, batuan fosfat dengan bantuan bakteri Pseudomonas sp, Bacillus sp dan jamur micoriza.Hasil penelitian menunjukkan bahwa pupuk organik yang didapat mempunyai rasio C/N = 12 - 17°/ckandungan fosfor lebih besar dari 6 % dan kandungan kalium lebih tinggi dari 1 %. Pada pupuk organik ini mengandung hara mikro yaitu besi, seng dan mangan.

Abstract

Many methods for dewatering of sludge, such as natural evaporate by sun or by means of equipment. Three kind methods of electroplating sludge dewatering by using equipment hare been studied, i.e : centrifugal, filter press and vacuum filter. The result shows that centrifugal has the best performance in term of reduction speed of sludge weight, moisture content of dry cake, and also time. The use of coagulant, thickener and polymerin dewatering can increase flock formation , therefore can accelerate the process. Coagulant addition is necessary in dewatering by using centrifugal method.

Abstract

Disposal of ex-dry cell is one of some waste which is potential for environmental pollution, because dry cell containt heavy metal and other material which is characteristic toxic.This research show the impact disposal of this dry cell. Result from lechate test show that heavy metal which is contained in dry cell shall be leachate in water, moreover in acid condition.

Abstract

One of the solution of waste problem is converted them to become a product which can give benefit for human being. Banana peel is a raw material for producing pectin. From five kind 's banana peel which is used the use of ambon 's banana peel produced the higher content of low metoksil pectin, i. e 3 - 5 %, followed by raj a serai 's banana peel, i. e 1 %, low metoksil . The use of acid as an extraction agent will influence the result
