Abstract: Contaminated nutrients in wastewater is critical problem of worldwide. The aim of this study was nitrogen and phosphorus treatment from dormitory wastewater of Srinakharinwirot University Ongkaruk by Acrostichumaureum L. and Eucalyptus globulus Labill. The plants were cultured in the pot and treated wastewater for 4 cycles. The differed plant weight was compared the efficiency in nitrogen and phosphorus treatment. The result found that Eucalyptus globulus Labill which is perennial plant had better efficiency in nitrogen and phosphorus treatment than Acrostichumaureum L. which is aquatic plant. The plant could grow well in wastewater and removed nutrients until passed standard criteria for short time. Moreover, plant biomass increased after nitrogen and phosphorus treatment for one month. These results showed the sustainable system in nutrients treatment from wastewater. Eucalyptus globulus Labill is new selected plant to remove nutrients and suit to apply for nitrogen and phosphorus tr

Abstract: Pithecellobium Jiringan (Jack) Prain (P.Jiringan) is one of the medicinal plant sources that consist of antioxidant compounds. The aim of this study was to investigate the effects of supercritical carbon dioxide (SC-CO2) extraction parameters on solubility and to determine the equilibrium constant of P.Jiringan oil in SC-CO2 and correlated the data with Chrastil and del Valle & Aguilera models. The experimental were conducted at temperatures ranging from 40 oC to 70 oC and pressure from 27.58 MPa to 44.82 MPa. The extraction duration was 60 minutes. The result shows the solubility of oil increased as the density of CO2 increased at constant temperature. The solubility experimental data correlated with both model was good agreement with more that 95% similarity where the Chrastil model was the best model correlated with the experimental data since the AARD% of Chrastil model (0.206%) is lowest compared to AARD% of del Valle and Aguilera model (0.5818). In addition, SC-CO2 give the highe
