Application of groundwaters and its effect on environment: a case river in Iran
There are some water basins in Iran. The Persian Gulf and the Caspian Sea are the best examples. Also there are some rivers in Iran that are originated from them, for example: The Karoon river and Kore river. The The Karoon river is the biggest one in Iran. It passes from Khuzestan state cities. In Shushtaras an aincient city in Khuzestan, this river has a meander through itself and so a setting dam was built in its route. The setting dam named "Bande Mizzan" divides the The Karoon water flowing to another artificial crevasee named "Gar-Gar". The shape and area of the windows on the dam for controlling water currents follow hydraulic and civil engineering concepts. By this, it would be possible to prevent destruction of the coastal zone in Shushtarand coastal erosion has been decreased notably. In fact there are 9 gates as controlling windows on the face of the The Band-e-Mizzan with a scientific engineering view. The hydraulic pattern used in building the dam is followed for other setting dams in Iran. It has been useful to protect coastal zone in cities near rivers and use river water in life and agricultural well. Deby of water flowing through the gates in the dam is calculated and sedimentation has a very small value. Following civil engineering regulations would be useful in building coastal cities and ports like Shushtar In this paper, we model dominant current deby in the meander in rout of the The Karoon river, Shushtar domain

Efektivitas Penggunaan Jenis Pelarut dan Asam dalam Proses Ekstraksi Pigmen Antosianin Kelopak Bunga Rosella (Hibiscus sabdariffa L)
Anthocyanin is pigments are red, purple and blue that commonly found in plants and can be used as a natural dye. One kind of plant that can be extracted as a source of natural dyes and contain anthocyanin is rosella petals flower. The use of solvents and acids are the factors that determine the quality and quantity of anthocyanin that extracted from rosella petals flower. Therefore in this study will be assessed the influence of the use of appropriate solvents and acids in the process of extraction of anthocyanin from rosella petals flower. Types used are varieties rosella sabdariffa. This research was conducted using Randomized Block Design Factorial consisting of 2 factors that is the type of solvent (J) consisting of ethanol and methanol, as well as the second factor which is the type of acid (P) consisting of tartaric acid, citric acid, and acid acetate. Based on the analysis it was found that the anthocyanin pigment (in red) in rosella petals flower is more stable in the acidic conditions (low pH). Type of acid (P) gives a very significant influence (P ≤ 0.01) toward pH values and significant influence (P ≤ 0.05) toward the intensity of the color. Type of solvent (J) that used gives a very significant influence (P ≤ 0.01) toward the intensity of the color, as well as a significant influence (P ≤ 0.05) on yield and levels of anthocyanin

Utilization of hemp (Cannabis sativa L.) as an alternative raw material for the production of three-layered particleboard
As the availability of high quality trees decreased and the price increased the wood base panel industry is looking to replace the common used wood by agricultural residues or fast growing trees and plants as well as agricultural plants like hemp (Cannabis sativa L.). Hemp offers characteristics that are similar to wood properties. In line with this research, three-layered particleboards under utilization of hemp material were developed. The hemp was used in combination with industrial produced particles to find out which amount of wood can be substituted by hemp and further to investigate which decreased densities can be realized by the use of hemp. Hemp can be used for the production of lightweight particleboards due to its lower bulk density compared to wood. All developed hemp/wood based particleboards were produced under industrial parameters in laboratory and pilot scale using conventional urea formaldehyde-resin, hardeners, and hydrophobic substances. The mechanical technological properties of all produced innovative particleboards and reference particleboards were determined according to current DIN/EN standards. In detail density profile, bending strength, internal bond strength, surface strength, and thickness swelling were determined. Compared to the produced reference particleboards, consisting only of wood particles, the developed hemp/wood particleboards possessed better mechanical-technological properties. Furthermore it was realized to produce particleboards with densities of 550 kg/m³ by using hemp due to its low bulk density which fulfills the given DIN/EN requirements. As an overall result we found out that hemp is a real alternative to nowadays used wood for the production of particleboards in general and for the production of lightweight particleboards in particular.

Effect of moisture content and amount of Hexane on in-situ transesterification of jatropha seeds for biodiesel production
The aim of this research is to study in-situ transesterification technique of jatropha seeds for biodiesel production. This research was conducted using a randomized factorial block design consisting of two factors that is moisture content of jatropha seeds (2% and 3%) and amount of hexane that used as a co-solvent (0 ml, 75 ml, 95 ml, 115 ml and 135 ml). The experimental result shows that the highest yieldbiodiesel of 78.72 % obtained at process condition of jatropha seeds moisture content of 2% and amount of hexane of 115 mL. The physico-chemical analysis of biodiesel procured the acid number of 0.35 mg KOH/g, density of 0.89 g/mL and viscosity of 3.04 mm2/ s that meet requirement of Indonesian Nasional StandardNo. 04-7182-2006.
