Abstract

ABSTRAK Penelitian ini bertujuan untuk mengetahui pengaruh yang signifikan dari model pembelajaran kooperatif tipe teams games tournament terhadap aktivitas dan hasil belajar siswa pada materi pokok listrik dinamis. Jenis penelitian ini adalah quasi eksperimen. Populasi dalam penelitian  adalah seluruh siswa kelas X semester 2 SMA Negeri 10 Medan T.P 2013/2014.Melalui teknik cluster random sampling terpilih kelas X-1 dan X-2 sebagai kelas eksperimen dan kelas kontrol. Instrumen berupa tes pilihan berganda yang telah di uji dengan validitas konten dan lembar observasi aktivitas siswa. Data rata-rata nilai pretes kelas eksperimen dan kelas kontrol adalah 39,17 dan 34,47. Pada pengujian data pretes kedua kelas diperoleh bahwa data berdistribusi normal dan homogen. Selain itu data juga diuji dengan menggunakan uji beda dan diperoleh kesimpulan bahwa kemampuan kedua kelas sama. Kemudian diberikan perlakuan yaitu kelas eksperimen denganmodel pembelajaran Kooperatif tipe TGT dan kelas kontrol denganmodel pembelajaran konvensional. Data postes yang diperoleh pada kelas eksperimen dan kelas kontrol adalah 73,61 dan 61,71. Kemudian dilakukan uji hipotesis memberikan bahwa thitung > ttabel (4,179>1,667) untuk taraf signifikansi 0.05, sehingga dapat diambil kesimpulan bahwa hasil belajar kelas yang menggunakan model pembelajaran kooperatif tipe TGT lebih tinggi dari dari hasil belajar kelas yang menggunakan model pembelajaran konvensional.   Kata kunci:  Kooperatif Tipe TGT, quasi eksperimen, Hasil Belajar   ABSTRACT This study aims to determine the significant influence of cooperative learning model Teams Games Tournament on activity and learning outcomes of students in the subject matter of dynamic electric. This research is quasi-experimental. The population is the entire second semester of tenth grade students of SMA Negeri 10 Medan T.P 2013 / 2014. Trough the cluster random sampling technique was selected classes X-1 and X-2 as the experimental class and the control class. Instrument in the form of multiple-choice tests that have been tested with content validity and observation of student activity sheets. Average data values ​​pretest experimental class and control class was 39.17 and 34.47. In both classes of the test data obtained pretest that the data were normally distributed and homogeneous. In addition, data was also tested using different test and it is concluded that the ability of the same class. Then given treatment that is experimental class with TGT Cooperative learning model and grade control with conventional learning models. Posttest data were obtained in the experimental class and the control class is 73.61 and 61.71. Then test the hypothesis gives that tcount> t table (4.179> 1.667) for the 0.05 level, so it can be concluded that the results of classroom learning using cooperative learning model TGT higher than classroom learning outcomes using conventional learning models.

Abstract

The potential well is a simple example that generally used to present an understanding of quantum mechanics. In this article, we used infinite spherical well model to evaluate the thermodynamic processes in a quantum Carnot engine. The energy of the particles depended on the value of n and l lead to complex calculations. For simplicity we used the φ100 and φ200 quantum states to determine work and efficiency of a quantum Carnot machine. The results obtained show that efficiency depends on the value of  which is the ratio of RC and RB.

Abstract

One of the nuclear atomic models represented by Skyrmion was the Skyrme model. This model was a modified nonlinear sigma model with a Skyrme field where the classical solution use generalized sixth order terms and potential terms. The binding energy that will be studied in the Skyrme SU(2) model is to generalize the second order nonlinear sigma model terms with sixth order derivative terms. The Lagrangian will be obtained for these two terms to find the BPS (Bogomolny Prasad Sommerfield) solution for the profile function numerically. The result of numerical calculation will be used to calculate static energy and rotational energy, where the characteristic of the nucleus can be observed from these two energies. Furthermore, the value of the coupling constant in the Lagrangian Skyrmion will be calculated from the static energy and rotational energy obtained previously. These values are expected to help in the application of Skyrme model for many research physics field.

Abstract

ABSTRAK   Pada artikel ini, teleportasi kuantum satu qubit dengan empat keadaan Bell sebagai kanal kuantum telah dikaji secara eksplisit. Empat keadaan Bell yang digunakan dinyatakan dalam bentuk kompak. Hasil kajian menunjukkan bahwa teleportasi kuantum satu qubit dengan empat keadaan Bell dapat dilakukan untuk mengirim informasi kuantum dari pengirim (Alice) ke penerima (Bob) setelah hasil pengukuran oleh Alice dikirim melalui kanal klasik. Untuk hasil pengukuran ,  dan  dari setiap keadaan Bell , ,  pada persamaan 1, terdapat satu kemungkinan di mana Bob tidak perlu melakukan transformasi uniter untuk merekonstruksi qubitnya dan selebihnya Bob perlu melakukan transformasi uniter. Untuk keadaan Bell , Bob perlu melakukan transformasi uniter pada qubitnya dari setiap hasil pengukuran Alice.   Kata  kunci—Keadaan Bell, qubit, teleportasi kuantum.   ABSTRACT   In this article, one-qubit quantum teleportation with four Bell states as quantum channel has been studied explicitly. Four Bell states used are expressed in compact form. The result of study shown that one-qubit teleportation quantum with four Bell states can be carried out to send quantum information from the sender (Alice) to the receiver (Bob) after Alice’s measurement results are send via classical channel. For the measurement results are ,  dan  from each Bell state , ,  in equation 1, there is one possibilty where Bob does not need to perform a unitary transformation to reconstruct his qubit and the rest Bob needs to perform a unitary transformation. For Bell state , Bob needs to perform a unitary transformation on his qubit from each of Alice’s measurements.   Keywords—Bell state, qubit, quantum teleportation.

Abstract

This study aims to determine public opinion regarding Universitas Pertahanan Republik Indonesia (UNHAN RI). As a new university, responses regarding public opinion need to be carried out so that the university can provide better services and educational programs. To see the public response to UNHAN RI, a Machine Learning method is used, namely Naïve Bayes. This Naïve Bayes modeling can help to classify public sentiment analysis towards UNHAN RI. By Naïve Bayes modeling, an accuracy value of 60.78% was obtained with three classification results, namely positive, negative, and neutral. The largest classification results were obtained in the positive class of 60.8%, the neutral class of 33.3%, and the negative class of 5.9%..
