Mices were randomly divide into four (4) groups of six (6) mices per group. The experimental groups ware treated as follows: Group I treated with no received treatment, Group II with 1,25 %, Group III with 2,5 %, and Group IV with 5 % black tea extract. The extract was orally administered 1 ml/100 g body weigh for 35 days. The epididymis weight, sperm count, motility, viability and normal sperm morphology changes  were determined. The epididymis weight, sperm count, motility, viability and normal sperm were decreased. Treatment with highest dose 5 % of the extract resulted in a significant decreased when compared to the control. Result showed that black tea extract has potential for use as antifertility for animal in future.</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: black tea extract, mice fertility</span>

These sequences are particulary useful in representation theory of algebras.</p><p>Key words:<strong> </strong>almost split morphisms, , irreducible morphisms, almost split sequences </p>

ANALISIS PERILAKU PEMILIH PADA SURVEY PRA PEMILU 2009 MENGGUNAKAN METODE CHAID

2016 · JOURNAL_SUBMISSION ·

<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>

KAJIAN SIFAT MAGNETIK SEDIMEN TELUK KATURAI PULAU SIBERUT KEPULAUAN MENTAWAI

2016 · JOURNAL_SUBMISSION ·

<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>

This article is about developing “resiliency”, a new paradigma of student development that offers schools a coherent. The foundation for the resiliency paradgma is a dramatic new perspective on how children and adolescence bounce back from stress, trauma, and risk in their lives that is emerging from the fields of psychiatry, psychology, and sociology. An understanding of resiliency, its importance, and the way schools can help students bounce back and evolve into more competent and successful learners is needed now more than ever. In this article, resiliency is defined and six-step plan of action for resiliency building is introduced.</em></p><strong>Kata Kunci:</strong><span class="Apple-converted-space"> </span>resiliensi remaja, mengatasi stress sekolah</div>

In embryology widely used terms that will clarify a process, and the state or the name of a body part, such as teratology, is part of a study of embryology and cause birth defects. Fetuses and embryos as another name for the developing fetus. Individual development process involves five kinds of processes, namely the growth, differentiation, cellular interactions, movement and metabolism. The fifth process will always be found in every stage of human development (day after day and week after week). Embryology process closely related to the presence and action of genes in the body. Advances in technology have shown that the lack of regulation in the body at the cellular level is called the molecular regulation and signaling.</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;"><strong> </strong></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 ; embryology, developmental of biology</span>
