The method used is the method of Branch And Bound together with the simplex method with a solution in the form of binary integer program .. By this method it was found that all the variables that represent each project is worth the cost of the current minimum, so that the entire project could be done with minimum total cost is Rp 17,789,289,600.00. This is in accordance with the reality on the ground that all projects can be realized by the Department of Road Infrastructure West Sumatra province.</p><p style="margin: 1em 0px; color: #111111; font-family: Arial, Verdana, Helvetica, sans-serif; font-size: 11.2px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: #fafafa;">Key words: branch and bound method, simpleks method, integer biner</p>

Examination carried out by using potassium permanganate (KMnO4) and dragon fruit skin by observing the color changes. Examination of formalin in 5 samples showed similar results to know that the 5 samples contain formaldehyde are all positive.</p><em style="color: #111111; font-family: Arial, Verdana, Helvetica, sans-serif; font-size: 11.2px; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: #fafafa;">Key word: formalin, tahu, KMNO<sub>4</sub>, Dragon Fruit skin</em>

The experiment was used t-test to compare halal slaugtering and bacteria contamination. The results showed that the place expedience was not significantly different between slaughtering place in market. The halal slaugtering practice was not significantly different for those ten places of slaughtering.

The purpose of this research is to study the effect of bismuth films in the determination of arsenic. In this study, the addition of bismuth ions with a concentration of 200 ppb. Voltammograms can be seen from quite a significant difference between the peak current generated by As (III) films coated with a non-bismuth bismuth films. Visible peak current of As (III) is higher if the addition of bismuth films. This proves the statement Nagaosa, et al who stated that there are mixed effects of bismuth in the determination of As (III) although the mechanism remains unclear.</p><p style="margin: 1em 0px; color: #111111; font-family: Arial, Verdana, Helvetica, sans-serif; font-size: 11.2px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: #fafafa;">Keyword: film bismuth, arcenic, differential pulse, anodic, stripping voltammetry</p>

The study was conducted in the x-ray radiology Hospital National Stroke Bukittinggi. The study sample consisted of urine male and female babies who drink only breast milk and urine only baby girls and boys who drank ation and additional milk. CR image retrieval is performed three days (22, 25 and 26 September 2014) with a voltage variation of 50 and 60 kV and 100 mA using a strong current and exposure time of 5 ms. The image was analyzed visually, and physical image quality. The results showed that visual image acquisition of the third day and with two different voltage variations indicate that there are differences in the brightness, contrast and sharpness of the image. Analysis of image quality (based grafi line profile image) shows the pattern of the same line profile image on the third day of taking images at a voltage of 60 kV. Physical Analysis of the image showed that the urine samples tested had a pattern of linear attenuation coefficient value equal to the voltage of 60 kV on three different days. Linear attenuation coefficient values greatest U1 and U3 linear attenuation coefficient on the third day of the smallest image retrieval. The big difference in the value of the significant linear attenuation coefficient between U1 and U3 sample is related to differences in the urine purification unclean baby boys and baby girls.</p><span style="color: #111111; font-family: Arial, Verdana, Helvetica, sans-serif; font-size: 11.2px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: #fafafa; display: inline !important; float: none;">Key words: baby boy urine, urine baby girl, computed radiography, law unclean in Islam</span>
