HUBUNGAN SIKAP PERCAYA DIRI TERHADAP KETERAMPILAN DRIBBLING DALAM PERMAINAN SEPAKBOLA

Tujuan dari penelitian ini adalah untuk mengetahui hubungan sikap percaya diri terhadap keterampilan dribbling dalam permainan sepakbola di ekstrakulikuler MAN 2 Bandung. Metode yang digunakan dalam penelitian ini adalah deskriptif dengan sampel penelitian yang diambil berjumlah 20 siswa. Desain penelitian ini mengunakan korelasional ditujukan untuk mencari hubungan antara dua variabel yaitu percaya diri dan keterampilan dribbling. Dengan instrumen yang digunakan adalah observasi GPAI (game performance assessment instrumen), dan pemberian angket (kuesioner) dan dokumentasi penelitian. Berdasarkan hasil analisis koefisien korelasi (pearson product moment) bahwa siswa yang mengikuti ekstrakulikuler sepakbola menunjukkan adanya hubungan yang sangat rendah antara sikap percaya diri terhadap keterampilan dribbling sebesar 0,011 dan dari penemuan penelitian sikap percaya diri memiliki persentase 82,76% dan untuk persentase keterampilan dribbling 82,44%. Maka dapat disimpulkan hasil ini menunjukkan terdapat hubungan sikap percaya diri terhadap keterampilan dribbling dalam permainan sepakbola siswa ekstrakulikuler di MAN 2 Bandung. Rekomendasi untuk peneliti selanjutnya bukan saja meneliti dan meningkatkan rasa percaya diri tetapi juga meningkatkan keterampilan dribbling dalam permainan sepakbola untuk dapat menciptakan siswa yang mampu mengendalikan diri pada saat bermain.;---The purpose of this study was to determine the relationship of confident attitude towards skills dribbling in the game football in extracurricular MAN 2 Bandung. The method used in this study is descriptive the sample taken is students which follow extracurricular which amounts to 20 students. Design this research use research correlational addressed to seek the relationship between two variables without any attempt to affect these variables. The instrument is observation GPAI (game performance assessment instrumen), and give of Questionnaire and research documentation. Based on the results of these research show that students who take extracurricular to their very low correlation between a confident attitude towards dribbling skills amounted to 0,011 and from research finding a confident attitude has percentage of 82,76 % and 82,44 % percentage of dribbling skills. It can be concluded this result show there is a relation of confidence attitude towards dribbling skills on the game of football extracurricular in MAN 2 Bandung. The recommendation for next research not only research and increase confident but too increase of dribbling skills in the game football to for sould create student that competent control self in the game

Phytochemical content and antioxidant properties of Bornean wild durian from Sabah

Borneo is the centre of diversity of the genus Durio (family: Malvaceae; local name: durian). Durian fruit is known to contain high amounts of the major bioactive compounds (as antioxidants) such as anthocyanins, carotenoids, polyphenols and flavonoids. Two types of wild durian species, namely Durio kinabaluensis Kosterm. & Soegeng (durian tupoloh) and Durio oxleyanus Griff. (durian sukang) were studied. The 80% methanolic extracts of flesh, seed and peel (mesocarp and exocarp) were analysed for antioxidant activities, total phenolic and total flavonoid content. The antioxidant activities were determined using three parameters; 2,2-diphenyl-1-picrylhydrazyl radical assay (DPPH), 2,2'-Azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) radical cation assay, and Ferric reducing antioxidant power assay (FRAP). Durio kinabaluensis mesocarp extract displayed the highest antioxidant properties and total phenolic content. The non-edible parts of both durians (seed and peel) exhibited higher phytochemical contents and antioxidant properties compared to the flesh parts. This data may contribute to the pharmaceutical applications, health benefit information of wild durians and helps in popularising the potential of these fruits in international markets and ultimately protects them from extinction

Design of high performance copyright protection watermarking based on lifting wavelet transform and bi empirical mode decomposition

This paper developed new and efficient image watermarking scheme for copyright protection based on Lifting wavelet transform (LWT) and Bi- dimensional Empirical Mode Decomposition (BEMD). A LWT has been selected because it is fast, less computational cost and maintains the integrity of the recovered watermark. The BEMD transform can separate the image from the most robust to the least sensitive or fragile frequency bands. This advantage is utilised in this study for the purpose of embedding the watermark in the robust part of BEMD, i.e. the residue (r). In addition, the embedding process has been performed in the low sub-band of LWT decomposed image as the low sub-band is more robust to image processing such as JPEG compression. The robust watermark which is grey scale image is decomposed using DWT to enhance the security and select only high sub-band as it has less impact on the quality of the watermarked image. As a result, the original image’s visual quality can be preserved and the concealed watermark could be successfully retrieved even if the watermarked images have undergone severe attacks like JPEG, rotation, Gamma correction, filtering, additive noise, translation, shearing, and scaling. Furthermore, the improved scheme offers greater robustness against many image processing operations, in comparison to the current schemes about copyright protection

Economic Geography and Human Rights

This is a working paper.This paper investigates the geo-political and international economic aspects of human rights performance using a pooled cross-section time-series data set. We start with simple descriptive accounts of the recent geographic history of human rights performance. We then test for basic economic effects of income and then apply tools from the spatial economics literature to examine the degree to which clusters of relative human rights performance exist. Using spatial weighting models we analyse the spatial impact of proximity and human rights performance of neghbours on overall levels of human rights performance. Unlike previous studies, our approach treats this spatial impact as partly endogenous: one country’s human rights performance may affect its neighbours through a variety of potential geographical spillover mechanisms. The spatial weighting models take into account size and distance of neighbours in order to compare each country’s human rights performance with what would be predicted by regression on a weighted average of its neighbours’ performance. The findings sugest that there are (a) geographical clusters of human rights performance and (b) size and proximity effects for human rights performance, both of which have significant implications for the promotion and protection of human rights
