Adhesion Effect

A brand new self-compensated capacitive fuel level sensor has been proposed in this paper. Through mathematics manipulation and theoretical analysis, we design the self-compensated structure of capacitive level sensor. The multiple segmentation structure makes compensation for temperature and medium possible. Furthermore, the effect caused by adhesion on the sensor electrodes if the adhesion fails to return initial position when the plane’s attitude is changing has been analyzed. Additionally, based on RF admittance theory, the transducer which can eliminate the adhesion effect has been designed and implemented using phase-locked sampling technique. Through level experiment and data analysis, the fuel level sensor proved to achieve all the destinations, including compensation for temperature and medium and elimination of adhesion effect. Hence, the accuracy of level measurement has been improved.

The Impact

Based on the observation of the writer it can be indicated that low level of ability of football player base of SSB SKB MuaraBungo. There are some factors caused this, such as exercise methods, physical conditions, nutritional status and infrastructure facilities. This study  aims to explain the influence of the self-inspection style and the convergent style of the dribbling ability of football. The population in this study is SSB players SKB MuaraBungo (U.13-U.15) which amounted to 75 people. The sampling technique was purposive sampling with 30 samples.Moreover, the data of dribbling soccer capability is taken by the coach and the research team. The test instrument is dribbling test. Data analysis technique using t test. The result of data analysis shows that: 1) there is impact of self-check force toward dribbling ability of player SSB SKB MuaraBungo with t test 7,132>ttable 2,145; 2) the impact of convergent style on dribbling ability of SSB players SKB MuaraBungo with t test 7,613>ttable 2,145,3 ) self-check style is more effective than convergent style to increase dribbling ability of SSB SKB player with tcount of 7,132>ttable 2,145 for self check style and ttest result 7,613>ttable 2,145 for convergent style, which means there is difference between the two styles.

A cross-capacitance liquid level sensor is based on the principle of cross capacitance. This study designed a new single-tube cross-capacitance fuel-level sensor. The fuel-level measurement model is established for a single-tube cross-capacitive sensor, and the relationship between the measured liquid level and sensor output capacitance is derived. The characteristics of the sensor were tested experimentally. The experimental results demonstrate that the linearity error of the liquid-level sensor of the single-tube calculation for the spacecraft is ±0.48%, the repeatability error is ±0.47%, and the hysteresis error is ±0.68%. The cross-capacitive fuel-level sensor developed in this study can be used in the fuel tank of spacecrafts owing to its low weight and high precision.

AbstrakSelf-efficacy calon guru matematika masih kurang. Oleh karena itu, perlu dilakukan analisis mengenai self-efficacy calon guru matematika sehingga dapat diketahui aspek self-efficacy yang perlu ditingkatkan. Tujuan penelitian ini yaitu untuk menganalisis self-efficacy calon guru matematika dalam mengajar matematika. Metode penelitian yang digunakan yaitu kualitatif dengan menggunakan teknik purposive sampling. Sampel yang diambil sebanyak tiga orang calon guru matematika jurusan pendidikan matematika di Institut Pendidikan Indonesia. Analisis data dilakukan secara kualitatif. Hasil penelitian menunjukkan bahwa calon guru matematika memiliki keyakinan dalam penguasaan pengetahuan matematika, namun merasa kurang yakin bahwa dirinya mampu untuk menyampaikan materi matematika kepada siswa. Kurangnya keyakinan ini berakibat pada kemampuan pedagogis calon guru matematika.  Self-Efficacy of Mathematics Prospective TeachersAbstractThe self-efficacy of prospective mathematics teachers is still lacking. Therefore, it is necessary to analyze the self-efficacy of prospective mathematics teachers so that it can be seen which aspects of self-efficacy need to be improved. The purpose of this study was to analyze the self-efficacy of prospective mathematics teachers in teaching mathematics. The research method used is qualitative by using a purposive sampling technique. The sample taken was three prospective mathematics teachers majoring in mathematics education at the Indonesian Institute of Education. The data analysis was done qualitatively. The results showed that the prospective mathematics teacher had confidence in the mastery of mathematical knowledge, but felt less confident that he was able to convey mathematics material to students. This lack of confidence results in the pedagogical abilities of prospective mathematics teachers.

ABSTRACT             The aims of this research are for knowing the relation between self-image and “selfies” attitude to students of Sarjanawiyata Tamansiswa University in Faculty of Psychology and for knowing how big the self-image role towards “selfies” attitude.            The subjects of this research were 18-23 years old female of Psychology Faculty from academic year 2009 until 2014. The sampling taking technique is used by Purposive Sampling technique. The data analysis method used in this research was Product Moment Correlation.            The results from data analysis of self-image variable towards “selfies” attitude showed that the value r 0,322 with p = 0,001 (p < 0,05). Based on those results of correlations, it stated that were significant positive relations between self-image and “selfies” attitude to students of Sarjanawiyata Tamansiswa University in Faculty of Psychology. It means that, the effectives impact of self-image towards “selfies” attitude were 10,4%. This was also showed that 89,6% “selfies” attitude determined by the others influencing factors. Keywords: Self-image, Attitude, Selfie
