PENGARUH PENAMBAHAN POLY ALUMINIUM CHLORIDE (PAC) TERHADAP TINGKAT KEKERUHAN, WARNA, DAN TOTAL SUSPENDED SOLID (TSS) PADA LEACHATE (AIR LINDI) DI TPAS PUTRI CEMPO MOJOSONGO SURAKARTA
MetadataShow full item record
The goals of this research is to know influence of additional Poly Aluminium Chloride to reduce of turbidity, colour and total suspended solid. This research is true experiment with pretest and posttest control group design. The sample in this research is leachate and every treatment of each 1 litre and the control not given the PAC, and the treatment given PAC, and obtained a optimum dose with the criterion of result of clear water meagrely sediment and do not there are effervescence that is at dose 6 gram/litre,and then from the dose made base in conducting experiment to know the storey;level kekeruhan, colour and TSS. Pursuant to hypothesis result with the t testt with the level significant 5%(α : 0,05) obtained p value p of each variable turbidity is 0,026, colour is 0,001, and TSS is 0,001, so that p value < α. Conclusion which can be taken that there is influence of addition PAC to reduced turbidity, colour and TSS from leachate.
