ROSMAWATYAbstract This study was conducted to investigates suitability of restaurant and housing wastewater to be reused as fertilizer for food crops. High concentration of wastewater applied to soil resulted into decreasing plant growth, however in low concentration (suitable) could increase the biomass of plants. Wastewater of restaurants in Pekanbaru contained the macro and micro essential nutrient (N, P,K, Ca, Mg and Ca). It is proven that there was only small significant difference in the performance of plant growth between restaurant, housing wastewater and commercial control (pure water). It can be seen that general restaurants and housing wastewater were able to perform as well as organic fertilizer. This result could be used as an alternative for substitution of organic fertilizer. |
