MENINGKATKAN KEMAMPUAN MOTORIK KASAR ANAK MELALUI PEMBELAJARAN TARI KREASI BALI
Penelitian ini dilakukan berdasarkan permasalahan kemampuan motorik kasar anak kelompok B-1 PAUD Kasih Sayang Bunda yang belum optimal. Kemampuan motorik kasar anak berkembang dengan optimal melalui stimulasi diluar tingkat yang dicapai hanya melalui kematangan. Tujuan dari penelitian ini yaitu untuk mengetahui apakah pembelajaran tari kreasi Bali dapat meningkatkan kemampuan motorik kasar anak kelompok B-1 PAUD Kasih Sayang Bunda. Metode yang digunakan adalah Penelitian Tindakan Kelas (PTK). Partisipan penelitian ini adalah anak-anak kelompok B-1 PAUD Kasih Sayang Bunda berusia 5-6 tahun yang berjumlah 15 anak. Hasil penelitian menunjukan peningkatan di setiap siklus setelah diterapkannya pembelajaran tari kreasi Bali. Terlihat dari pra siklus tidak ada anak yang berada pada kategori Berkembang Sesuai Harapan (BSH), pada akhir siklus I mengalami sedikit peningkatan dan diakhir siklus II tidak ada anak yang berada pada kategori Belum Berkembang (BB). Sehingga dapat disimpulkan bahwa pembelajaran tari kreasi Bali dapat meningkatkan kemampuan motorik kasar anak di Kelompok B-1 PAUD Kasih Sayang Bunda. Hal ini terlihat dari anak dapat menggerakan lengan, kaki, leher dalam melakukan gerakan yang berpindah tempat, keseimbangan dan menggunkan alat, dari gerakan yang sederhana ke gerakan yang kompleks dengan iringan tari kreasi Bali. Dengan adanya hasil dari penelitian tersebut, maka pembelajaran tari kreasi Bali dapat direkomendasikan untuk guru dalam kegiatan pembelajaran di Taman Kanak-kanak.;---This research is made based on problem of children’s rough motor ability of group B-1 PAUD Kasih Sayang Bunda that is not optimal yet. The ability of children’s rough motor develops optimally through stimulation out of the achieved level is only through maturity. The aim of this research is to find the objective’s condition, application of Bali creation dance learning, and improvement of children’s rough motor ability of group B-1 PAUD Kasih Sayang Bunda. The method used is Classroom Action Research (CAR). The participant of this research is fifteen children aged 5-6 years of group B-1 PAUD Kasih Sayang Bunda. The result of this research shows improvement in every cycle after the application of Bali creation dance learning. It can be seen from pre-cycle that there is no children in category Developed as Expected (DAE), and there is some improvement at the end of cycle I and no children in category Undeveloped (U) at the end of cycle II. Therefore, it can be concluded that Bali creation dance learning able to improve children’s rough motor ability of group B-1 PAUD Kasih Sayang Bunda. This can be seen from children that are able to move their hands, feet, and necks in performing movement, balance, and using tools from simple movement to complex movement with Bali creation dance offbeat. With the result of this research, it can be recommended for teachers in learning activity in preschool
Improving the entanglement transfer from continuous variable systems to localized qubits using non Gaussian states
We investigate the entanglement transfer from a bipartite continuous-variable
(CV) system to a pair of localized qubits assuming that each CV mode couples to
one qubit via the off-resonance Jaynes-Cummings interaction with different
interaction times for the two subsystems. First, we consider the case of the CV
system prepared in a Bell-like superposition and investigate the conditions for
maximum entanglement transfer. Then we analyze the general case of two-mode CV
states that can be represented by a Schmidt decomposition in the Fock number
basis. This class includes both Gaussian and non Gaussian CV states, as for
example twin-beam (TWB) and pair-coherent (TMC, also known as two-mode-coher
ent) states respectively. Under resonance conditions, equal interaction times
for both qubits and different initial preparations, we find that the
entanglement transfer is more efficient for TMC than for TWB states. In the
perspective of applications such as in cavity QED or with superconducting
qubits, we analyze in details the effects of off-resonance interactions
(detuning) and different interaction times for the two qubits, and discuss
conditions to preserve the entanglement transfer.Comment: revised version, 11 pages, 7 figures (few of them low-res
Further work at Kilise Tepe, 2007-11: refining the Bronze to Iron Age transition
The excavations at Kilise Tepe in the 1990s inevitably left a range of research questions unanswered, and our second spell of work at the site from 2007 to 2011 sought to address some of these, relating to the later second and early first millennia. This article gathers the architectural and stratigraphie results of the renewed excavations, presenting the fresh information about the layout and character of the Late Bronze Age North-West Building and the initial phases of the Stele Building which succeeded it, including probable symbolic practices, and describing the complex stratigraphic sequence in the Central Strip sounding which covers the lapse of time from the 12th down to the seventh century. There follow short reports on the analyses of the botanical and faunal materials recovered, a summary of the results from the relevant radiocarbon dating samples and separate studies addressing issues resulting from the continuing study of the ceramics from the different contexts. Taken together, a complex picture emerges of changes in settlement layout, archi¬tectural traditions, use of external space, artefact production and subsistence strategies during the centuries which separate the Level III Late Bronze Age settlement from the latest Iron Age occupation around 700 BC
Simulations and Experiments on Polarisation Squeezing in Optical Fibre
We investigate polarisation squeezing of ultrashort pulses in optical fibre,
over a wide range of input energies and fibre lengths. Comparisons are made
between experimental data and quantum dynamical simulations, to find good
quantitative agreement. The numerical calculations, performed using both
truncated Wigner and exact phase-space methods, include nonlinear and
stochastic Raman effects, through coupling to phonons variables. The
simulations reveal that excess phase noise, such as from depolarising GAWBS,
affects squeezing at low input energies, while Raman effects cause a marked
deterioration of squeezing at higher energies and longer fibre lengths. The
optimum fibre length for maximum squeezing is also calculated.Comment: 19 pages, lots of figure
Atomic Quantum State Teleportation and Swapping
A set of protocols for atomic quantum state teleportation and swapping
utilizing Einstein-Podolsky-Rosen light is proposed. The protocols are suitable
for collective spin states of a macroscopic sample of atoms, i.e. for
continuous atomic variables. Feasibility of experimental realization for
teleportation of a gas sample of atoms is analyzed.Comment: 4 pages, 1 figur
Spin-spin interaction and spin-squeezing in an optical lattice
We show that by displacing two optical lattices with respect to each other,
we may produce interactions similar to the ones describing ferro-magnetism in
condensed matter physics. We also show that particularly simple choices of the
interaction lead to spin-squeezing, which may be used to improve the
sensitivity of atomic clocks. Spin-squeezing is generated even with partially,
and randomly, filled lattices, and our proposal may be implemented with current
technology.Comment: 4 pages, including 4 figure
Polarization squeezing with cold atoms
We study the interaction of a nearly resonant linearly polarized laser beam
with a cloud of cold cesium atoms in a high finesse optical cavity. We show
theoretically and experimentally that the cross-Kerr effect due to the
saturation of the optical transition produces quadrature squeezing on both the
mean field and the orthogonally polarized vacuum mode. An interpretation of
this vacuum squeezing as polarization squeezing is given and a method for
measuring quantum Stokes parameters for weak beams via a local oscillator is
developed
