Published: January 2019

Abstract
Chromium (Cr) is a very important element examined for last decades on many expert fields. Its toxicity, mobility and bio-availability are strongly dependent on its oxidation state, Cr(III) and Cr(VI). Hexavalent form Cr(VI) is a known carcinogen with many harmful effects on living organisms, on the other hand trivalent Cr(III) form is an important micronutrient necessary for lipid metabolism. Contamination of the environment by Cr may come from anthropogenic industrial pollution or from naturally enriched sites, especially ultramafic rocks and their derived soils. Environmental conditions of soils and water represent a very complex system, which makes reliable assessment of its fate and potential toxicity and transport a really difficult task. A number of studies have been performed to describe Cr behaviour in these systems, as well as to optimize its determination, especially speciation methods. The main objective of this contribution is to summarize and present the today’s knowledge about the occurrence, speciation, and behaviour of Cr in soil environment, with a specific emphasis to description of differences between naturally enriched and anthropogenically contaminated soils.

Published: January 2019

This paper proposed Canny edge detection to detected saliency map on traffic sign. The edge detection functions by identifying the bounds from an object on an image. The edge of an image is an area that has a strong intensity of light.The pixel intensity of an image changes from low to high values or otherwise. Detecting the edge of an image significantly will decrease the amount of data and filters insignificant information by not deleting necessary structure from the image. The image used for this paper is a digital capture of a traffic sign with a background. The result of this study shows that Canny edge detection creates saliency map from the traffic sign and separates the road sign from the background. The image result tested by calculating the saliency distance between a tested image and trained image using normalized Euclidean distance. The value ofnormalized Euclidean distance is set between 0 to 2. The testing process is done by calculating the nearest distance between the tested vector features and trained vector features. From the examination as a whole, it can be concluded that road sign detection using saliency map model can be built by Canny edge detection. From the whole system examination, it resulted a accuracy value of 0,65. This value shows that the data was correctly classified by 65%. The precision value has an outcome of 0,64, shows that the exact result of the classification is 64%. The recall value has an outcome of 0,94. This value shows that the success rate of recognizing a data from the whole data is 94%.

Published: January 2019

The amount of refinery water discharged to the environment from oil industry has increased vigorously in current times. Recent research has been focusing on the use of membrane technology for the refinery processed water treatment. Membrane Distillation (MD) is an emerging technology that has been highly marked by its low-energy requirement and high desalination efficiency. However, conventional MD membranes (i.e. PVDF) are not feasible for oil-water separation processes. That is due to the oleo-philic property of the membrane and thus, causes membrane fouling and halts the production of mass flux. An anti-oil-fouling membrane is essential for a successful oil-water separation by MD. Underwater-oleophobic as well as omniphobic are two different approaches in fabricating such membranes. The former approach is based on the asymmetric surface wettability, whereas the latter is attributed to the surface structure that is characterized by having a very large contact angle for all liquids. However, such composite membranes are characterized by their lower porosity, smaller pore size, but with unique surface slippage, in comparable with the conventional PVDF membranes. As such, in this work, high fidelity numerical simulation of DCMD is performed using non-isothermal Computational Fluid Dynamics (CFD) validated model in order to assess the role of the anti-oil-fouling membrane properties on the performance of the DCMD. Results are presented in terms of temperature polarization coefficient, mass flux, latent heat flux, and thermal efficiency. Results show the compromising effect of membrane porosity to 45% reduces the mass flux and thermal efficiency respectively by 68% and 40%, and reduction of pore size to the half (i.e. 50 nm) can cause a reduction by 50.6% in mass flux and 24.18% in thermal efficiency compared to the baseline (i.e. 100 nm). On the other hand, the omniphobic slippage effect leads to a noticeable gain of 16% in DCMD mass flux with slight gain in thermal efficiency. This can maximize mass flux and thermal efficiency to be as much as 50.3 kg/m2 h and 69%, respectively.

Blewah (C. melo var. Cantalupensis) is one specific type of melon with fresh and fragrance arome when the fruit is ripe. Mostly the plant is grown in Java island of Indonesia. There is no research-based information about technique of cultivationof this plant, so this experiment was done to study population density to determine the optimal spacing for growth and yield of blewah. The experiment has been implemented from February 2016 until May 2016 in the experimental field of the University of Bengkulu. This study used a complete Randomized Complete Block Design with different population density treatments i.e.: plant density of 4 plants per plot of 10 m2 (plant spacing 100 cm x 250 cm); plant density of 6 plants per plot, (plant spacing 100 cm x 166 cm); plant density of 8 crops per plot (spacing of 100 cm x 120 cm); plant density of 10 plants per plot (plant spacing 100cm x 100 cm); plant density of 12 plants per plot (plant spacing 100 cm x 83 cm); plant density of 14 plants per plot (plant spacing 100 cm x 72 cm); and plant density of 16 plants per plot (plant spacing 100cm x 62 cm). Each treatment was repeated 3 times. The experiment showed that the optimal spacing for growing blewah was at population density 12 plants/10 m2 or 12,000 plant/ha, plant spacing 100 cm x 83 cm. This arrangement of plant yielded the length of plant, the number of branches, the diameter of the fruit, the plant dry weight, the weight of the fruit per plot, and fruit thickness of 224.47 cm, 3.67, 9.61 cm, 22.15 g, 7044.80 g, and 2.21 cm respectively.Keywords: blewah, Cucumis melo var.

Success in a breeding program is primarily determined by the availability of information about the genetic diversity of the genetic material used and the expected heritability of the character to be improved. The objective of this study was to determine genetic diversity and heritability of growth and yield components of 10 curly chili genotypes. This research was conducted in September 2015 - February 2016 in the Medan Baru field experiment of Faculty of Agriculture at Kandang Limun Village, Muara Bangkahulu Subdistrict, Bengkulu City. The experiment was arranged in Completely Randomized Design (CRD) with ten genotypes and six replications. The genotypes used were Local Payakumbuh, Ferosa, Laris, Kopay, Romario, Keriting Hitam, Local Curup, Bogota, Sempurna and Mario. The results showed that genetic diversity of the ten varieties was narrow based on plant height variables, dichotomous height, stem diameter, flowering age, harvest age, fruit length, fruit diameter, weight per fruit and number of fruits. Stem diameter, fruit length, fruit diameter and weight per fruit had moderate heritability estimates; meanwhile, anthesis and number of fruits showed low heritability.
