Magnet contribute greatly to health. As a result, a variety of products using a mag-net as a healing tool. The use of magnets for health is presumably because in the human body there are also magnetic. The purpose of this study is to examine the magnetic analysis in the human body. This research uses descriptive qualitative method. The data collected by the technique of writing literature. The results obtained by the analysis that the human body contains a metallic element that is iron. Basic properties of the mag-netic material is located on the magnetic properties of the core elements of the human body shaper is hydrogen, H2O molecules and iron. In the human body Fe contained in the grains of red blood (hemoglobin). Other substances that have magnetic properties but is not as strong as the Fe in hemoglobin is the molecule H2O.Key words: magnets, the human body

This study aimed to see whether there are differences in the profile line image and the linear attenuation coefficient in the urine baby boys and baby girls who drink only breast milk alone and additional milk with computed radiography, and relation to differences in impurity law. 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.Key words: baby boy urine, urine baby girl, computed radiography, law unclean in Islam

Formalin is a toxic chemical that is commonly used as a preservative for biological samples and in various industries. But in practice many abused formaldehyde as a preservative foods such as tofu, meatballs, anchovies, etc. wet fish. When food is consumed can cause interference with the metabolism of the body's organs and systems. A research on the investigation of formaldehyde, especially in out circulating in the market Batusanggkar. 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.Key word: formalin, tahu, KMNO4, Dragon Fruit skin

This study aims to determine the design specifications set tool-making experiments to determine the kinetic coefficients and a coefficient of restitution of the collision of two objects using laser diode and sensor based LDR arduino uno. Results of the study is the design tool set of experiments could measure the kinetic coefficient between the glass material with glass with a relative error of 2.5%, wood with wood with a relative error of 1%, and steel materials with wood with a relative error of 0.5%. The coefficient of restitution is obtained for glass with glass material is 0.062, wood with wood is 0:49, and steel materials with wood is 0:22.Key words: kinestetic cooficient, restitution, sensor, laser dioda, LDR, arduino uno
