Nyamplung (Calophyllum inophyllum L.) is a plant with great potential as fuel source that can be developed in Indonesia. The oil content of nyamplung seeds 60-75%. This study aims to optimize the process extracting from using hexane solvent at various operating conditions and obtain optimum extraction conditions. In stage, will carried out several variations, namely temperature (35-45oC); time ...

Raw goat milk pricing is based on the milk quality especially on fat, solid not fat (SNF) and density. Therefore, there is a need of approach for composition quantization. This study applied radial basis function network (RBFN) to calibrate fat, SNF, and density with visible and near infrared spectra (400~2500 nm). To find the optimal parameters of goal error and spread used in RBFN, a response...

Mulberry is one of the most widely used traditional Chinese medicines. Anthocyanins are the main bioactive components of mulberry, and possess important biological activities, such as antimicrobial, anti-inflammatory and antioxidant activities. This study investigated the ultrasound-assisted extraction (UAE) of anthocyanins from mulberry by using response surface methodology (RSM). The extracti...

the aim of this work was to develop a new and simple coacervative extraction method for the preconcentration and spectrophotometric determination of cu(ii) in water samples. dithizone was used as the chelating agent while an anionic surfactant, namely sodium dodecyl sulfate (sds), was used as extracting agent at room temperature. central composite design (ccd) based on response surface methodol...

In this present study the dissolved air flotation (DAF) system was investigated for the treatment of Kermanshah Oil Refinery wastewater. The effect of three parameters on flotation efficiency including of flow rate (outflow from the flotation tank), saturation pressure and coagulant dosage on chemical oxygen demand (COD) removal was examined experimentally. All the experiments were done under a...
