Pengembangan Instrumen Telaah RPP Dan Supervisi Akademik Berbasis Keterampilan Abad 21 Guru Sekolah Binaan SPMI Kota Palangka Raya

Arranging lesson plans refers to the characteristics of students not in accordance with the demands of 21st century learning. This study aims to develop the Lesson Plan review instrument and supervision of 21st century skill-based learning using research and development (R&D). There are three design models for instrument development, namely: 1) a preliminary study, 2) the development stage, and 3) the evaluation stage. The results showed that (1) the factual model of the Lesson Plan review instrument and the supervision of learning in Central Kalimantan Province did not meet the suitability of the preliminary, core, and closing activities as well as the description in the Lesson Plan, so that it had not been used as a teacher's reference in perfecting the Lesson Plan; (2) instrument development begins with, (a) reviewing the literature so that 5 (five) components of the Lesson Plan are obtained and three stages of supervision are carried out, (b) validating the instruments according to the expert includes validity, level of importance, and usefulness on average. the average percentage reached 92.19. The evaluation phase is to test the practicality of the instrument showing (a) the observer makes it easy to study lesson plans and supervision of learning, (b) assist teachers in perfecting lesson plans according to the minimum substance in the lesson plans, (c) schools have measurement tools for lesson plans and learning supervision, and (d) Excel-based instruments that have been successfully developed refer to the skills of 21st century teachers and the industrial revolution 4.0.Menyusun RPP mengacu pada karakteristik peserta didik belum sesuai dengan tuntutan pembelajaran abad 21. Jalan pintas yang dilakukan adalah menggunakan RPP sekolah lain. Akibatnya indikator pencapaian kompetensi (IPK), model pembelajaran, dan penilaian tidak sesuai KD. Penelitian ini bertujuan mengembangkan instrumen telaah RPP dan supervisi pembelajaran berbasis keterampilan abad 21 menggunakan research and development (R & D). Desain model pengembangan instrumen ada tiga, yaitu: 1) studi pendahuluan melalui review instrumen telaah RPP dan supervisi pembelajaran, 2) tahap pengembangan yaitu telaah kesesuaian instrumen, validasi telaah instrumen menurut ahli, menyusun instrumen berdasarkan hasil validasi, dan 3) tahap evaluasi uji kepraktisan instrumen telaah RPP dan supervisi pembelajaran. Hasil penelitian menunjukkan bahwa (1) model faktual instrumen telaah RPP dan supervisi pembelajaran di Provinsi Kalimantan Tengah belum memenuhi  kesesuaian kegiatan pendahuluan, inti, dan penutup maupun deskripsi dalam RPP, sehingga belum digunakan sebagai acuan guru dalam menyempurnakan RPP; (2) pengembangan instrumen diawali dengan, (a) melakukan kajian literatur sehingga diperoleh 5 (lima) komponen RPP dan tiga tahapan pelaksanaan supervisi, (b) melakukan validasi instrumen menurut ahli meliputi sahih (akurasi), tingkat kepentingan, dan kebermanfaatan dengan rata-rata prosentase mencapai 92,19. Tahap evaluasi yaitu melakukan uji coba kepraktisan instrumen menunjukkan (a) observer menjadi mudah melakukan telaah RPP dan supervisi pembelajaran, (b) membantu guru dalam menyempurnakan RPP sesuai dengan substansi minimal dalam RPP, (c) sekolah memiliki alat ukur telaah RPP dan supervisi pembelajaran, dan (d) Instrumen berbasis excel yang berhasil dikembangkan mengacu keterampilan guru abad 21 dan revolusi industri 4.0

Lyapunov instability of fluids composed of rigid diatomic molecules

We study the Lyapunov instability of a two-dimensional fluid composed of rigid diatomic molecules, with two interaction sites each, and interacting with a WCA site-site potential. We compute full spectra of Lyapunov exponents for such a molecular system. These exponents characterize the rate at which neighboring trajectories diverge or converge exponentially in phase space. Quam. These exponents characterize the rate at which neighboring trajectories diverge or converge exponentially in phase space. Qualitative different degrees of freedom -- such as rotation and translation -- affect the Lyapunov spectrum differently. We study this phenomenon by systematically varying the molecular shape and the density. We define and evaluate ``rotation numbers'' measuring the time averaged modulus of the angular velocities for vectors connecting perturbed satellite trajectories with an unperturbed reference trajectory in phase space. For reasons of comparison, various time correlation functions for translation and rotation are computed. The relative dynamics of perturbed trajectories is also studied in certain subspaces of the phase space associated with center-of-mass and orientational molecular motion.Comment: RevTeX 14 pages, 7 PostScript figures.

Lattice Boltzmann Simulations of Liquid Crystal Hydrodynamics

We describe a lattice Boltzmann algorithm to simulate liquid crystal hydrodynamics. The equations of motion are written in terms of a tensor order parameter. This allows both the isotropic and the nematic phases to be considered. Backflow effects and the hydrodynamics of topological defects are naturally included in the simulations, as are viscoelastic properties such as shear-thinning and shear-banding.Comment: 14 pages, 5 figures, Revte

Dynamical ensembles in stationary states

We propose as a generalization of an idea of Ruelle to describe turbulent fluid flow a chaotic hypothesis for reversible dissipative many particle systems in nonequilibrium stationary states in general. This implies an extension of the zeroth law of thermodynamics to non equilibrium states and it leads to the identification of a unique distribution \m describing the asymptotic properties of the time evolution of the system for initial data randomly chosen with respect to a uniform distribution on phase space. For conservative systems in thermal equilibrium the chaotic hypothesis implies the ergodic hypothesis. We outline a procedure to obtain the distribution \m: it leads to a new unifying point of view for the phase space behavior of dissipative and conservative systems. The chaotic hypothesis is confirmed in a non trivial, parameter--free, way by a recent computer experiment on the entropy production fluctuations in a shearing fluid far from equilibrium. Similar applications to other models are proposed, in particular to a model for the Kolmogorov--Obuchov theory for turbulent flow.Comment: 31 pages, 3 figures, compile with dvips (otherwise no pictures

Master equation approach to the conjugate pairing rule of Lyapunov spectra for many-particle thermostatted systems

The master equation approach to Lyapunov spectra for many-particle systems is applied to non-equilibrium thermostatted systems to discuss the conjugate pairing rule. We consider iso-kinetic thermostatted systems with a shear flow sustained by an external restriction, in which particle interactions are expressed as a Gaussian white randomness. Positive Lyapunov exponents are calculated by using the Fokker-Planck equation to describe the tangent vector dynamics. We introduce another Fokker-Planck equation to describe the time-reversed tangent vector dynamics, which allows us to calculate the negative Lyapunov exponents. Using the Lyapunov exponents provided by these two Fokker-Planck equations we show the conjugate pairing rule is satisfied for thermostatted systems with a shear flow in the thermodynamic limit. We also give an explicit form to connect the Lyapunov exponents with the time-correlation of the interaction matrix in a thermostatted system with a color field.Comment: 10 page

REWARMING PRETERM INFANTS ON A HEATED, WATER FILLED MATTRESS

Sixty low birthweight infants (1000-2000 g) admitted to a neonatal care unit in Turkey were studied. Those not requiring intensive care were randomly assigned for treatment either in a cot on a heated, water filled mattress kept at 37 degrees C (n = 28) or in air heated incubators with a mean air temperature of 35 degrees C (n = 32). On admission 53 (88.3%) of the infants had body temperatures between 30 degrees and 36 degrees C. There was good correlation between axillary and rectal temperatures in the infants while they were hypothermic. Normal temperatures were achieved within the first day and remained within this range during the subsequent days after admission in all the infants treated on the heated, water filled mattress, whereas they were not achieved until three days later in the incubator group. The neonatal mortality among those treated on the heated, water filled mattress was 21%, and among those treated in the incubator 34%. The heated, water filled mattress provides a good alternative to skin to skin contact with the mother, and to the use of a complex and expensive incubator for rapidly attaining and maintaining normal temperatures in the low birthweight newborn
