Peran Teknologi Informasi Dalam Komunikasi Antar Budaya Dan Agama

; Perkembangan teknologi informasi telah menunjukkan kemajauan sangat cepat. Kemajuan itu telah menyebabkan manusia lebih mudah untuk berhubungan satu sama lain. Informasi dan peristiwa yang terjadi berbagai belahan dunia dengan cepat dapat diketahui oleh manusia di benua lain. Dalam wacana keagamaan kontemporer menjelaskan bahwa agama mernpunyai banyak dimensi dan tidak lagi seperti dahulu memahami bahwa hanya masalah ketuhanan. kepercayaan, iman, dan sebagainya, tetapi lebih dari itu semua. Dimulai pada isu-isu ekonomi, politik, ilmu pengetahuan dan teknologi, lingkungan hidup, sejarah, perdamaian dan sebagainya. Gejala umum yang dapat dirasakan atau dilihat hari ini, terutama dalam kaitannya dengan kehidupan beragama adalah jumlah ilmuwan yang tinggal di kota-kota besar sangat menyadari bahwa ilmu pengetahuan dan teknologi tidak dapat menyelesaikan semua masalah kehidupan manusia. Karena ilmu pengetahuan dan teknologi tidak dapat memberikan ketenangan pikiran bagi mereka merasa ada sesuatu yang "kurang pas" atau "hilang" dari diri mereka sendiri. Mereka mencoba untuk menemukan "hilang" dalam beberapa cara, antara lain dengan melihat ajaran spiritual agama. Splendor kehidupan beragama di kota-kota besar setelah memudar sebelumnya dihuni oleh lapisan atas dari segi ekonomi dan pengetahuan merupakan salah satu indikator bagaimana besarnya kehilangan kesadaran. Suatu informasi atau pesan yang disampaikan komunikator kepada komunikan akan komunikatif apabila terjadi proses psikologis yang sama antara insan-insan yang terlibat dalam proses tersebut. Dengan perkataan lain, informasi yang disampaikan komunikator kepada komunikan adalah situasi komunikatif seperti itu akan terjadi bila terdapat etos pada diri komunikator. Kata Kunci: Peran, Teknologi Informasi, Budaya The development of information technology has shown very rapid progress. It has led to human progress is easier to relate to one another. Information and events happening around the world quickly it can be seen by humans on other continents. In contemporary religious discourse to explain that religion mernpunyai many dimensions and no longer as it used to understand that the only theological matters. trust, faith, and so on, but most of all. Beginning on economic issues, politics, science and technology, environment, history, peace and so on. Common symptoms that can be felt or seen today, especially in relation to religious life is the number of scientists who live in big cities are well aware that science and technology can not solve all the problems of human life. Because science and technology can not give peace of mind to those felt something was "not fit" or "missing" from themselves. They try to find "lost" in some way, such as by seeing the spiritual teachings of religion. Splendor of religious life in large cities after fading previously inhabited by the upper layers of the economic and knowledge is one indicator of how the magnitude of loss of consciousness. An information or message conveyed communicator to the communicant to be communicative event of the same psychological process between beings who are involved in the process. In other words, the information conveyed communicator to the communicant is a communicative situation like that would happen if there is a communicator yourself ethos.

Degenerate Fermi Gas of 87^{87}Sr

We report quantum degeneracy in a gas of ultra-cold fermionic $^{87}$Sr atoms. By evaporatively cooling a mixture of spin states in an optical dipole trap for 10.5\,s, we obtain samples well into the degenerate regime with $T/T_F=0.26^{+.05}_{-.06}$. The main signature of degeneracy is a change in the momentum distribution as measured by time-of-flight imaging, and we also observe a decrease in evaporation efficiency below $T/T_F \sim 0.5$.Comment: 4 pages, 3 figure

Inelastic and elastic collision rates for triplet states of ultracold strontium

We report measurement of the inelastic and elastic collision rates for ^{88}Sr atoms in the (5s5p)^3P_0 state in a crossed-beam optical dipole trap. This is the first measurement of ultracold collision properties of a ^3P_0 level in an alkaline-earth atom or atom with similar electronic structure. Since the (5s5p)^3P_0 state is the lowest level of the triplet manifold, large loss rates indicate the importance of principle-quantum-number-changing collisions at short range. We also provide an estimate of the collisional loss rates for the (5s5p){^3P_2} state.Comment: 4 pages 5 figure

Ultracold Neutral Plasmas

Ultracold neutral plasmas are formed by photoionizing laser-cooled atoms near the ionization threshold. Through the application of atomic physics techniques and diagnostics, these experiments stretch the boundaries of traditional neutral plasma physics. The electron temperature in these plasmas ranges from 1-1000 K and the ion temperature is around 1 K. The density can approach $10^{11}$ cm$^{-3}$. Fundamental interest stems from the possibility of creating strongly-coupled plasmas, but recombination, collective modes, and thermalization in these systems have also been studied. Optical absorption images of a strontium plasma, using the Sr$^+$ ${^2S\_{1/2}} -> {^2P\_{1/2}}$ transition at 422 nm, depict the density profile of the plasma, and probe kinetics on a 50 ns time-scale. The Doppler-broadened ion absorption spectrum measures the ion velocity distribution, which gives an accurate measure of the ion dynamics in the first microsecond after photoionization.Comment: 12th International Congress on Plasma Physics, 25-29 October 2004, Nice (France

Demonstrating Universal Scaling in Quench Dynamics of a Yukawa One-Component Plasma

The Yukawa one-component plasma (OCP) is a paradigm model for describing plasmas that contain one component of interest and one or more other components that can be treated as a neutralizing, screening background. In appropriately scaled units, interactions are characterized entirely by a screening parameter, $\kappa$. As a result, systems of similar $\kappa$ show the same dynamics, regardless of the underlying parameters (e.g., density and temperature). We demonstrate this behavior using ultracold neutral plasmas (UNP) created by photoionizing a cold ($T\le10$ mK) gas. The ions in UNP systems are well described by the Yukawa model, with the electrons providing the screening. Creation of the plasma through photoionization can be thought of as a rapid quench from $\kappa_{0}=\infty$ to a final $\kappa$ value set by the electron density and temperature. We demonstrate experimentally that the post-quench dynamics are universal in $\kappa$ over a factor of 30 in density and an order of magnitude in temperature. Results are compared with molecular dynamics simulations. We also demonstrate that features of the post-quench kinetic energy evolution, such as disorder-induced heating and kinetic-energy oscillations, can be used to determine the plasma density and the electron temperature.Comment: 10 pages, 12 figures, to be submitted to Physical Review

Photoassociative spectroscopy at long range in ultracold strontium

We report photoassociative spectroscopy of $^{88}$Sr$_2$ in a magneto-optical trap operating on the ${^1S_0}\to{^3P_1}$ intercombination line at 689 nm. Photoassociative transitions are driven with a laser red-detuned by 600-2400 MHz from the ${^1S_0}\to{^1P_1}$ atomic resonance at 461 nm. Photoassociation takes place at extremely large internuclear separation, and the photoassociative spectrum is strongly affected by relativistic retardation. A fit of the transition frequencies determines the ${^1P_1}$ atomic lifetime ($\tau=5.22 \pm 0.03$ ns) and resolves a discrepancy between experiment and recent theoretical calculations.Comment: 4 pages, 4 figures, submitte

Runaway evaporation for optically dressed atoms

Forced evaporative cooling in a far-off-resonance optical dipole trap is proved to be an efficient method to produce fermionic- or bosonic-degenerated gases. However in most of the experiences, the reduction of the potential height occurs with a diminution of the collision elastic rate. Taking advantage of a long-living excited state, like in two-electron atoms, I propose a new scheme, based on an optical knife, where the forced evaporation can be driven independently of the trap confinement. In this context, the runaway regime might be achieved leading to a substantial improvement of the cooling efficiency. The comparison with the different methods for forced evaporation is discussed in the presence or not of three-body recombination losses

Using Absorption Imaging to Study Ion Dynamics in an Ultracold Neutral Plasma

We report optical absorption imaging of ultracold neutral plasmas.Images are used to measure the ion absorption spectrum, which is Doppler-broadened. Through the spectral width, we monitor ion equilibration in the first 250ns after plasma formation. The equilibration leaves ions on the border between the weakly coupled gaseous and strongly coupled liquid states. On a longer timescale of microseconds, we observe radial acceleration of ions resulting from pressure exerted by the trapped electron gas.Comment: 4 pages, 4 figure

Spectroscopic determination of the s-wave scattering lengths of 86Sr and 88Sr

We report the use of photoassociative spectroscopy to determine the ground state s-wave scattering lengths for the main bosonic isotopes of strontium, 86Sr and 88Sr. Photoassociative transitions are driven with a laser red-detuned by up to 1400 GHz from the 1S0-1P1 atomic resonance at 461 nm. A minimum in the transition amplitude for 86Sr at -494+/-5 GHz allows us to determine the scattering lengths 610a0 < a86 < 2300a0 for 86Sr and a much smaller value of -1a0 < a88 < 13a0 for 88Sr.Comment: 4 pages, 3 figures, submitted to Physical Review Letter
