PERMASALAHAN-PERMASALAHAN TERKAIT DENGAN PROFESI GURU SD
Authors: Slameto Slameto
Published: March 2017

Profesionalisme guru sering dikaitkan dengan tiga faktor yang cukup penting, yaitu kompetensi, sertifikasi, dan tunjangan profesi. Ketiga faktor tersebut diprediksi mempengaruhi kualitas pendidikan. Mengingat hasil-hasil penelitian belum mendukung kerangka berpikir seperti itu, maka lahirlah 3 isu terkait dengan sertifikasi guru yaitu: peningkatan hasil belajar siswa yang diajar oleh guru pasca sertifikasi, rendahnya kualitas proises pembelajaran yang diampu oleh guru pasca sertifikasi dan perilaku guru yang kurang profesional. Oleh karena itu perlu pembinaan guru pasca sertifikasi yang harus dilaksanakan secara berkelanjutan, dikarenakan prinsip mendasar bahwa guru harus merupakan manusia pembelajar (a learning person). Sebagai guru profesional dan telah menyandang sertifikat pendidik, guru berkewajiban untuk terus mempertahankan profesionalismenya sebagai guru. Pengembangan kompetensi dan profesionalisme guru dapat dilakukan melalui upaya pembinaan dan pemberdayaan guru. Dengan demikian perlu upaya peninjauan lebih mendalam terhadap program sertifikasi guru dalam jabatan, khususnya tujuan dan makna sertifikasi, perlu ada upaya pembenahan mind set guru dan perlu ada program perawatan dan pengembangan profesionalisme bagi guru-guru yang telah lulus program sertifikasi, khususnya dalam upaya peningkatan mutu layanan pembelajaran. Pengembangan profesionalisme guru pasca sertifikasi perlu kompetensi manajemen, strategi pember­dayaan, supervisi pengembangan, dan pe-nelitian tindakan kelas.
PEMBERLAKUAN KURIKULUM SD/MI TAHUN 2013 DAN IMPLIKASINYA TERHADAP UPAYA MEMPERBAIKI PROSES PEMBELAJARAN MELALUI PTK
Authors: Mawardi Mawardi
Published: March 2017

Konsekuensi utama pemberlakuan kurikulum 2013 untuk jenjang SD/MI diantaranya pada cara mensinergikan pendekatan, model dan standar proses pembelajaran, serta cara menyusun dan melakukan penilaian. Dua komponen utama sistem pembelajaran ini merupakan komponen yang sangat erat kaitannya dengan peningkatan mutu pembelajaran. Pendekatan, model dan standar proses pembelajaran berkaitan dengan jaminan mutu prosesnya, sedangkan komponen penilaian berkaitan dengan akurasi dan validitas pengukuran mutu pembelajaran tersebut.  Pendekatan saintifik (5M) yang meliputi keterampilan proses mengamati, menanya, mengumpulkan informasi, mengasosiasi dan mengkomunikasikan  perlu disinergikan dengan standar proses eksplorasi, elaborasi, dan konfirmasi (EEK). Kedua keterampilan (5M dan EK) inilah yang menjadi pemandu bagi guru untuk memilih model (dan metode) pembelajaran serta alat penilaian otentik yang sesuai. Dalam rangka membantu para guru untuk mengimplemantasikan kurikulum 2013, Kementerian Pendidikan dan Kebudayaan menyiapkan buku guru dan buku siswa. Namun demikian para guru dapat memodifikasi dan mengembangkan sendiri. Pengembangan instrumen pembelajaran  disesuaikan dengan karakteristik para siswa dan lingkungan belajar-nya, sehingga mutu proses dan hasil pembelajaran dapat ditingkatkan. Pengem-bangan mutu pembelajaran seperti ini sekaligus menjadi sarana bagi para guru untuk  mengembangkan profesinya secara berkelanjutan. Permasalahannya adalah pemberlakuan kurikulum 2013 berimplikasi pada proses pengembangan keprofesian guru, misalnya bagaimana proses pelaksanaan penelitian tindakan kelas (PTK) yang selama ini telah dilakukan. Rambu-rambu pendekatan, model, sistem penilaian, buku guru dan buku siswa dalam kurikukum 2013 mestinya tidak membatasi ruang gerak guru dalam berinovasi.

Published: March 2017

Penelitian ini bertujuan untuk mengetahui ada tidaknya perbedaan hasil belajar matematika yang signifikan dalam penerapan model pembelajaran kooperatif tipe Numbered Head Together (NHT) dan model pembelajaran kooperatif tipe Student Teams Achivement Division (STAD) pada siswa kelas 5 SD Gugus Singoprono 1 dan 3 Simo. Subjek penelitian ini adalah siswa kelas 5B SDIT Al Falaah (SD swasta) dan SDN 02 Simo (SD Imbas) sebagai kelompok eksperimen 1, dan 5A SDIT Al Falaah (SD Swasta) dan SDN Putri (SD Imbas) sebagai kelompok eksperimen 2. Variabel dalam penelitian ini terdiri atas model NHT dan STAD sebagai variabel bebas, hasil belajar sebagai variabel terikat, dan pretest sebagai variabel kovariat. Pengumpulan data dilakukan dengan menggunakan instrumen soal tes dan lembar observasi. Teknik analisis data hasil penelitian ini menggunakan teknik deskriptif dan teknik statistik ANCOVA. Berdasarkan uji ANCOVA yang telah dilakukan terhadap skor posttest kelompok eksperimen 1 dan kelompok eksperimen 2 diperoleh hasil F hitung sebesar 10,303, pada taraf signifikansi/probabilitas 0,002; oleh karena nilai probabilitas tersebut < 0,05, maka H0 ditolak dan Ha diterima. Artinya terdapat perbedaan hasil belajar matematika yang signifikan pada siswa kelas 5 SD Gugus Singoprono 1 dan 3 dalam pembelajaran menggunakan model pembelajaran NHT dan STAD. Perbedaan hasil belajar Matematika yang signifikan tersebut didukung oleh perbedaan rerata dua sampel penelitian, dimana rerata hasil belajar pada penerapan model pembelajaran NHT sebesar 81, sedangkan rerata hasil belajar pada penerapan model pembelajaran STAD sebesar 74. Maknanya adalah bahwa perlakuan pembelajaran dengan model NHT memberikan dampak pada hasil belajar yang berbeda dan lebih tinggi daripada model pembelajaran STAD. Saran yang penulis ajukan berkenaan dengan hasil penelitian ini adalah guru dapat memilih model pembelajaran kooperatif tipe NHT dalam pembelajaran Matematika sebagai alternatif untuk meningkatkan hasil belajar siswa.

Erasmus rejected the scholastics’ theological method, i.e. the deriving of cogent conclusions from metaphysical principles by syllogistic, dialectical reasoning. In his own “theology” Erasmus reverts to the literary hermeneutics of Classical and patristic “rhetoric”. Hoffmann examines how Erasmus thus constructs a distinct theological framework and a distinct “rhetorical theology”. The present article discusses Hoffmann’s questions about such a theology, especially whether it is theology at all, and if so, at what level of the “systematic”. The article argues that Erasmus ignores an intrinsic and essential element in ancient rhetoric: the systematic intellectual armature of Classical and patristic metaphysics, of which dialectic is the organon or method.
Thomas More’s Reputation in Nineteenth-Century England
Authors: Wyland Russell M.
Published: March 2017

Thomas More inspired over 230 works of scholarship and biography in the nineteenth century, and from a sampling emerges the development of More’s image. From the political debate over the “Catholic Question” early in the century came oversimplifications of More’s life and times. During the middle years of the century, however, a corrective occurred as historians rethought More in light of archival materials. As More’s beatification neared. treatments of his life and thought shifted to an emphasis on his attempts at social reform and tolerance. This paper traces More’s fortuna through the nineteenth century, revealing the birth of what would today be called “Thomas More Studies. ”
A Review of Flywheel Energy Storage System Technologies and Their Applications
Authors: Amiryar Mustafa , Pullen Keith
Published: March 2017

Energy storage systems (ESS) provide a means for improving the efficiency of electrical systems when there are imbalances between supply and demand. Additionally, they are a key element for improving the stability and quality of electrical networks. They add flexibility into the electrical system by mitigating the supply intermittency, recently made worse by an increased penetration of renewable generation. One energy storage technology now arousing great interest is the flywheel energy storage systems (FESS), since this technology can offer many advantages as an energy storage solution over the alternatives. Flywheels have attributes of a high cycle life, long operational life, high round-trip efficiency, high power density, low environmental impact, and can store megajoule (MJ) levels of energy with no upper limit when configured in banks. This paper presents a critical review of FESS in regards to its main components and applications, an approach not captured in earlier reviews. Additionally, earlier reviews do not include the most recent literature in this fast-moving field. A description of the flywheel structure and its main components is provided, and different types of electric machines, power electronics converter topologies, and bearing systems for use in flywheel storage systems are discussed. The main applications of FESS are explained and commercially available flywheel prototypes for each application are described. The paper concludes with recommendations for future research.

A target tissue can be thermally coagulated in high-intensity focused ultrasound (HIFU) treatment noninvasively. HIFU thermal treatments have been clinically applied to various solid tumors. One of the problems in HIFU treatments is a long treatment time. Acoustically driven microbubbles can accelerate the ultrasonic heating, resulting in the significant reduction of the treatment time. In this paper, a method named “trigger HIFU exposure” which employs cavitation microbubbles is introduced and its results are reviewed. A trigger HIFU sequence consists of high-intensity short pulses followed by moderate-intensity long bursts. Cavitation bubbles induced in a multiple focal regions by rapidly scanning the focus of high-intensity pulses enhanced the temperature increase significantly and produced a large coagulation region with high efficiency.

The improved Johnson inclusion core model of indentation by conical and pyramidal indenters in which indenter is elastically deformed and a specimen is elastoplastically deformed under von Mises yield condition, was used for determination of mechanical properties of materials with different types of interatomic bond and different crystalline structures. This model enables us to determine approximately the Tabor parameter С = НМ/YS (where НМ is the Meyer hardness and YS is the yield stress of the specimen), size of the elastoplastic zone in the specimen, effective apex angle of the indenter under load, and effective angle of the indent after unloading. It was shown that the Tabor parameter and the size of elastoplastic deformation zone increase monotonically with the increase of the plasticity characteristic indentation test results significantly more informative.
Limitations and Constraints of Eddy-Current Loss Models for Interior Permanent-Magnet Motors with Fractional-Slot Concentrated Windings
Authors: Zhang Hui , Wallmark Oskar
Published: March 2017

This paper analyzes and compares models for predicting average magnet losses in interior permanent-magnet motors with fractional-slot concentrated windings due to harmonics in the armature reaction (assuming sinusoidal phase currents). Particularly, loss models adopting different formulations and solutions to the Helmholtz equation to solve for the eddy currents are compared to a simpler model relying on an assumed eddy-current distribution. Boundaries in terms of magnet dimensions and angular frequency are identified (numerically and using an identified approximate analytical expression) to aid the machine designer whether the more simple loss model is applicable or not. The assumption of a uniform flux-density variation (used in the loss models) is also investigated for the case of V-shaped and straight interior permanent magnets. Finally, predicted volumetric loss densities are exemplified for combinations of slot and pole numbers common in automotive applications.

The regional effects of climate change on forest ecosystems in the temperate climate zone of Europe can be modelled as shifts of forest vegetation zones in the landscape, northward and to higher elevations. This study applies a biogeographical model of climate conditions in the forest vegetation zones of the Central European landscape, in order to predict the impact of future climate change on the most widespread tree species in European deciduous forests—the European beech (Fagus sylvatica L.). The biogeographical model is supported by a suite of software applications in the GIS environment. The model outputs are defined as a set of conditions - climate scenario A1B by the Special Report on Emission Scenarios (SRES) for a forecast period, for a specified geographical area and with ecological conditions appropriate for the European beech, which provide regional scenarios for predicted future climatic conditions in the context of the European beech’s environmental requirements. These predicted changes can be graphically visualized. The results of the model scenarios for regional climate change show that in the Czech Republic from 2070 onwards, optimal growing conditions for the European beech will only exist in some parts of those areas where it currently occurs naturally. Based on these results, it is highly recommended that the national strategy for sustainable forest management in the Czech Republic be partly re-evaluated. Thus, the presented biogeographical model of climate conditions in forest vegetation zones can be applied, not only to generate regional scenarios of climate change in the landscape, but also as a support tool for the development of a sustainable forest management strategy.
Hydrogen Production by a Chlamydomonas reinhardtii Strain with Inducible Expression of Photosystem II
Authors: Batyrova Khorcheska , Hallenbeck Patrick C.
Published: March 2017

Chlamydomonas reinhardtii cy6Nac2.49 is a genetically modified algal strain that activates photosynthesis in a cyclical manner, so that photosynthesis is not active constitutively in the presence of oxygen, but is turned on only in response to a metabolic trigger (anaerobiosis). Here, we further investigated hydrogen production by this strain comparing it with the parental wild-type strain under photoheterotrophic conditions in regular tris-acetate-phosphate (TAP) medium with a 10-h:14-h light/dark regime. Unlike the wild-type, whose level of H2 production remained low during illumination, H2 production in the mutant strain increased gradually with each subsequent light period, and by the final light period was significantly higher than the wild-type. The relatively low Photosystem II (PSII) activity of the mutant culture was shown by low fluorescence yield both in the dark (Fv/Fm) and in the light (δF/Fm’) periods. Measurement of oxygen evolution confirmed the low photosynthetic activity of the mutant cells, which gradually accumulated O2 to a lesser extent than the wild-type, thus allowing the mutant strain to maintain hydrogenase activity over a longer time period and to gradually accumulate H2 during periods of illumination. Therefore, controllable expression of PSII can be used to increase hydrogen production under nutrient replete conditions, thus avoiding many of the limitations associated with nutrient deprivation approaches sometimes used to promote hydrogen production.
The Role of Geometrically Necessary Dislocations in Cantilever Beam Bending Experiments of Single Crystals
Authors: Husser Edgar , Bargmann Swantje
Published: March 2017

The mechanical behavior of single crystalline, micro-sized copper is investigated in the context of cantilever beam bending experiments. Particular focus is on the role of geometrically necessary dislocations (GNDs) during bending-dominated load conditions and their impact on the characteristic bending size effect. Three different sample sizes are considered in this work with main variation in thickness. A gradient extended crystal plasticity model is presented and applied in a three-dimensional finite-element (FE) framework considering slip system-based edge and screw components of the dislocation density vector. The underlying mathematical model contains non-standard evolution equations for GNDs, crystal-specific interaction relations, and higher-order boundary conditions. Moreover, two element formulations are examined and compared with respect to size-independent as well as size-dependent bending behavior. The first formulation is based on a linear interpolation of the displacement and the GND density field together with a full integration scheme whereas the second is based on a mixed interpolation scheme. While the GND density fields are treated equivalently, the displacement field is interpolated quadratically in combination with a reduced integration scheme. Computational results indicate that GND storage in small cantilever beams strongly influences the evolution of statistically stored dislocations (SSDs) and, hence, the distribution of the total dislocation density. As a particular example, the mechanical bending behavior in the case of a physically motivated limitation of GND storage is studied. The resulting impact on the mechanical bending response as well as on the predicted size effect is analyzed. Obtained results are discussed and related to experimental findings from the literature.
Improvement of Fracture Toughness in Epoxy Nanocomposites through Chemical Hybridization of Carbon Nanotubes and Alumina

Published: March 2017

The current study investigated the effect of adding a carbon nanotube–alumina (CNT–Al2O3) hybrid on the fracture toughness of epoxy nanocomposites. The CNT–Al2O3 hybrid was synthesised by growing CNTs on Al2O3 particles via the chemical vapour deposition method. The CNTs were strongly attached onto the Al2O3 particles, which served to transport and disperse the CNTs homogenously, and to prevent agglomeration in the CNTs. The experimental results demonstrated that the CNT–Al2O3 hybrid-filled epoxy nanocomposites showed improvement in terms of the fracture toughness, as indicated by an increase of up to 26% in the critical stress intensity factor, K1C, compared to neat epoxy.
