PENALARAN ILMIAH SISWA SMA PADA SEKOLAH YANG MENGGUNAKAN KTSP DENGAN KURIKULUM 2013

Penelitian deskriptif ini bertujuan untuk mengungkap kemampuan penelaran ilmiah siswa SMA pada materi biologi. Sebanyak 169 siswa kelas X, XI, dan XII dari sekolah yang menggunakan KTSP dan sekolah yang menggunakan urikulum 2013 mengikuti tes penalaran ilmiah dan wawancara. Angket siswa, hasil wawancara guru, dan observasi kegiatan pembelajaran dikumpulkan dan dianalisis. Penalaran ilmiah siswa dalam penelitian diidentifikasi melalui argumen siswa menggunakan Pola Argumen Toulmin (TAP) yang membagi komponen argumen menjadi claim, data, warrant, backing, qualifier, dan rebuttal. Analisis argumen siswa meliputi dua aspek, yaitu kelengkapan komponen argumen siswa dan koherensi argumen siswa. Hasil penelitian menunjukan bahwa pada aspek kelengkapan komponen, antara sekolah yang menggunakan KTSP dengan yang menggunakan kurikulum 2013 sama yaitu mencapai pada level 2 dengan perbedaan 1%, sekolah yang menggunakan KTSP (80%) dan sekolah yang menggunakan kurikulum 2013 (81%). Sementara pada aspek koherensi argumen, sebagian besar argumen siswa pada sekolah yang menggunakan KTSP (47%) dan sekolah yang menggunakan kurikulum 2013 (39%) merupakan argumen yang kurang koheren, yang berarti komponen data, warrant, dan backing tidak valid secara konsep ilmiah dan tidak relevan terhadap claim. Adapun faktor yang mempengaruhi dalam penalaran ilmiah siswa yaitu karena kurangnya pemahaman guru dalam melatih siswa untuk mempunyai kemampuan penalaran ilmiah.----------The scientific reasoning in the current research identified as the student arguments based on the Toulmin Argument Pattern (TAP).

Description de la compréhension du CECR Niveau A1 pour les enseignants de français dans les écoles secondaires à Bandar Lampung

The purpose of this study is to describe the competencies contained in the CECR A1 French language teaching standards in secondary schools in Bandar Lampung, and the 2013 curriculum objectives applied in schools. The method used to answer the problems is the descriptive-analytical method. According to the results of the questionnaires and the interviews conducted in five high schools, most French teachers already had already the knowledge of the CEFL, but limited to its relation with the DELF, not as a guide for the teaching standardized French at the international level. It also shows that teaching does not always follow the lesson plans. Because of this difference, teachers need training related to CEFL learning practices. It was therefore decided to provide training for teachers, leading to a convention of agreement governing the training of teachers in French learning practices according to level A1 of the CECR

A Highly Efficient White Luminescent Zinc (II) Based Metallopolymer by RGB Approach

Three aryl-hydrazone O,N,O tridentate ligands with a different electron-withdrawing substituent were prepared. The introduction of a flexible charged chain in the ligands guaranteed solubility in many organic solvents and in water. The increasing withdrawing aptitude of the substituents red-shifted the emission in the correspondent metallopolymers. The metallated polymers were obtained by grafting ligand-zinc (II) coordination fragments onto commercial poly-(4-vinylpyridine). Metallopolymers thin films exhibited red, green and blue emission colors defined by Commission Internationale d'Eclairage (CIE) coordinates and medium to excellent photoluminescence (PL) quantum yields (PLQYs) comparable with other highly-performing active materials for Light-Emitting Diodes (LEDs). By grafting a suitable mix of the three different coordination pendants, an efficient single-component white emissive metallopolymer with CIE (0.30, 0.31) was prepared. Thanks to the charged moiety, the polymers resulted miscible with an ionic liquid. The addition produced homogeneous polymeric layers with unaltered PL performances, potentially employable in Light-emitting Electrochemical Cells (LECs)

The effect of pH on equilibrium distribution of ammonia in air and river water

Ammonia is an important component in chemical industries. Very often, the water effluent of chemical plants contains ammonia, which may cause environmental problems. The equilibrium distribution of ammonia in air and water is hence of importance, especially in predicting the fate of this component in the environment, as well as in the design of equipment needed for the treatment of this effluent. In that system, two equilibria are involved, which are ionic and phase equilibria. In water phase, ammonia is present in two forms, free ammonia and ammonium ion. The two forms are in ionic equilibrium, in which the ionic equilibrium is affected by pH. Meanwhile, free ammonia in water is also in equilibrium with the ammonia in air (phase equilibrium). As a result, the equilibrium between ammonia in air and total ammonia in water is influenced by pH. Since effluent and natural water have a wide range of pH values, the effect of pH on that equilibrium needs to be studied Experimental and theoretical studies have been conducted and the results, which are represented in the form of mathematical model, can be applied to quantitatively predict the equilibrium distribution of ammonia at various value of pH, for the natural water studie

Effect of the Active Layer Thickness on the Device Performance of Polymer Solar Cells Having [60]PCBM and [70]PCBM as Electron Acceptor

Abstract Recently it has been shown that the use of [70]PCBM as electron acceptor in polymer solar cells can improve the current output of such devices because C70 derivatives have a stronger and broader absorption compared to C60 ones. In this work we studied the influence of the fullerene on the optical behaviour of the photoactive blend film of a polymer solar cell. We simulated the optical absorption of the active layer inside the device structure and we calculated the maximum achievable short circuit current density with the aim to correlate the variation of the optical constants to the output current of the device. Afterward, we realized several polymer solar cells and we proved the theoretical findings
