Abstract

Waste of the distillation of pogestemon cablin still havet high nutrient content and potentialas a good raw material of organic fertilizer . Rapid composting technology and efficient organicfertilizer will produce high quality compost. This study aim to determine the best conditions in termsof fermentation time 6,10,14,18,22 day and volume of bacteria (EM4): 2,4,8,10% EM4/solution wereadded to the N, P, K most in the process of making liquid fertilizer to use waste leaves the distillationof pogestemon cablin of N, P and K respectively 10.6% weight, 1.19% and 3.08% heavy weight andthe volume EM4 8% and the fermentation time of 14 days.Key words : pogestemon cablin, fermentation, ,liquid organic fertilizer, nitrogen,kalium, phospor

Abstract

Photokimia have used as by many alternative processing of water. Photokimia reaction is reaction of chemistry which is induction by light either trough indirect and also direct. Conversion ofr Energy light become chemical energy or electrics represent elementary principle of photokimia. To quicken reaction of conversion needed by the existence of catalis reffered as catalis system. Catalis will be active if obtaining light energy. In course of fotokimia will be formed by radical hydroxyl to degrade compound of organic underwater of waste like surfactant. The research dergradation of concentration surfactant used Titanium Dioxide catalis with light source the used is lamp of UV which variation of 15 watt, 30 watt and 36 watt. The objective of research to determine abilitry degradation of concentration of surfactant in waste of detergent. Result of research indicate that ability of degradation of be concentration use TiO2 counted 2,2 gr with result 96,5 %, time of radiating 2,5 hour and lamp energy 36 watt. Key words :Photokimia, Photokatalitik, Surfactan
