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.</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: magnets, the human body</span>

<p>This research studied about the the respondents characteristic at the legislative general pre-election in 2009. The researcher used statistic analysis to see the association and structural connection between variables as the characteristic of voters’ behavior. The data used in this study is gotten from the result of a survey on voters’ behavior in the form of counting and category data, that’s why the statistic methods used was CHAID. Analysis of CHAID showed that the variables having the strongest association with the party choice is age. CHAID method at the analysis of respondent characteristics of voters in the election resulted in five segments of the party choice of respondents. In each segment, the old party is still the party that is trusted by respondents to represent their voice in parliament.</p><p>Key words: voting behavior, interaction, chi-square, CHAID method</p>

<p>This study aimed to examine the magnetic properties of sediments from Teluk Katurai Siberut island Mentawai islands. The study on sediment samples from Teluk Katurai had been carried out by using three methods, i.e., measurements of AMS (Anisotropy of Magnetic Susceptibility) to determine the anisotropy shape of magnetic susceptibility, IRM (Isothermal Remanent Magnetization) to identify the their magnetic minerals contains based on the saturation curve, and AAS (Anisotropy of Anhysteretic Susceptibility) that produce anhisteritik susceptibility. From the stereonet plot and other anisotropy parameters were obtained that ellipsoid susceptibility form is oblate. It was also obtained that the type of magnetic mineral is magnetite based on magnetic saturation curves. Meanwhile the identification of grain size distribution was obtained by plotting the value of AMS versus AAS. The plots showed the magnetic grains of sediment was approximately 0.2 µm to 0.1µm.</p><span>Key words: magnetic susceptibility, anisotropy, anhisteritic susceptibility</span>

The respondents of this research were 339 students from Math, Physic and Biology Departmen who registered in 2008 - 2010 academic year. The logistic regression analysis showed that there were 3 factors that influence the students’ learning outcome significantly; their village, UN mean score and major in high school. The data analysis indicated that the students graduated from Islamic High School had a bigger chance to succes than students from Vocational School. UN mean score also can reflect the academic ability of the student significantly and the approriate major in high school (Science Studies) gave contribution to the students’ comprehension.

<p>The research study about the screening of the resistance of red chilli (<em>Capsicum annuum</em> L.) resulted from mutation induced by Ethyl Methane Sulphonate (EMS) on the second generation (M<sub>2</sub>) to antrachnose diseases has been done by using descriptive method to intensity diseases of Colletotrichum capsici from mutant fruit of second generation. The result showed that the intensity of antrachnose on red chilli generation ranged from 23.69% to 54.82% with tolerance criteria susceptible and very susceptible.</p><p>Key words: mutation induced, ethyl methane sulphonate, antraknosa red chille, antrachnose</p>
