The influences of climate change have also covered Stung Chrey Bak Catchment,with increasing the significant issues over water demands for irrigation schemes. Thus, the aim of this research is to predict water demands of each irrigation schemes through climate change scenarios, using Water Evaluation and Planning model (WEAP). Stung Chrey Bak catchment consists of seven irrigation schemes. Two demand management scenarios were developed for this s
Asian white radish is a popular root vegetable in asia. It can be consummed as fresh, dried, salted and pickle products. Japanese pickle vegetable (nukazuke) fermented in rice bran bed. There is no research related to this fermentation in Cambodia. Therefore, the ojective of this study is to optimize the white radish fermentation wtith rice bran. In this study, the physicochemical composition in white radish and rice bran were analyzed such as pH
Biodiesel is a renewable green fuel obtained through the transformation of animal and vegetable fats, as well as used oil. This biodiesel can replace fossil diesel. The production of biodiesel from recycled oils is comparable in quality to that virgin vegetable oil biodiesel with an added attractive advantage of being lower in price. The current research was therefore to study the production of biodiesel from used frying oil for fried banana in P
The presence of high arsenic content in groundwaters in Kandal, Cambodia has threatened about 1 million people and several people have already been exposed to arsenic. This study aims to investigate the removal of arsenic from Kandal groundwater by utilizing naturally available laterite from Kampong Cham in order to obtain safe drinking water for the people. The laterites were characterized with XRD, XRF, zeta potential analyzer, and surface area
Concentration of arsenic in groundwater was investigated at three villages (Chong Prek, Prek Tameng and Prek Thom) in the Kandal Province of Cambodia, which ranged from 80.9 μg/L (in Prek Tameng village) to 1420 μg/L (in Prek Thom village), with average and median concentrations of 463.16 and 217 μg/L, respectively. Iron concentration was also determined. Nearly all the twenty-five samples contained arsenic and iron concentrations exceeding the W
Due to human activities such as batik home industries, abattoirs, and tanneries, the existence of heavy metals in dug-well water has been known as the cause of groundwater pollution in Yogyakarta City. To treat this dug-well water, a batch adsorption experiment by utilizing the activated zeolite and bentonite was carried out. Prior to the treatment, the zeolite and bentonite were characterized by means of XRD, SEM, XRF, and various ICP and modifi
The Sidomulyo zeolitic and Kedungbedah bentonitic tuffs are respectively located in the Gunungkidul and the Boyolali regencies, Indonesia. The study of their mineralogical characteristics was primarily done. The petrographical analysis indicates that the Sidomulyo zeolitic or Kedungbedah bentonitic tuffs is composed of volcanic glass, quartz, plagioclase, and altered minerals. The XRD investigation reveals that the zeolite tuff contains clinoptil
Groundwater quality in Yogyakarta city has become the major concern due to the presence of heavy metals originated from batik home industries, slaughterhouses, and leather factories, especially in shallow groundwater. In response to the above problems, the naturally abundant zeolite and bentonite in Sidomulyo and Bandung areas were respectively sampled along with the metal-containing groundwater in Yogyakarta urban area for batch adsorption exper
The water requirement for the Chulsar Rice Crop is becoming a more and more common practice in Cambodia research, as it secures productivity and ensures constant the amount of water use. Effective water planning and management require accurate determination of crop water requirement so it plays an important role for irrigation practice. Consumptive water requirement is the amount of water potentially required meeting the evapotranspiration needs
Field experiment with the dimension of 47.7m × 55.5m were performed at Cambodian Agricultural Research and Development Institute (CARDI), Cambodia, from July 2013 to May 2014 to calculate the reference and crop evapotranspiration, and collected requirements input data for the CROPWAT model to estimate the rice water requirements of two seasons. Two types of rice crop was taken in this study. Phka Rumdoul rice, 120 days growing period, was observe
