Praktek E-government Dalam Administrasi Kependudukan Studi Pelaksanaan Perekaman E-ktp Di Kabupaten Pemalang

This study was conducted to describe the implementation of programe in the “electronik Kartu Tanda Penduduk/e-KTP” (electronic civil ID card) in Pemalang regency. The program is motivated by the development of information and communication technologies are adopted into the system of governance in the form of e-government. Implementation of e-KTP is intended to manifest valid demographic data base. So that it can be support the implementation of good governance.To explain the research implementation of e-KTP, then used descriptive qualitative research methods. Subject and object in this study is the Department of Population and Civil Registration Pemalang, Head of Population Registration, Technical Supervisor District, operator services, and society in general. The method of data collection was through interviews and observations with the selection of purposive informants.The study says that the implementation of e-KTP recording in Pemalang can be said is not maximized. Many constraints make the implementation of this program to be blocked, such as a less effective socialization, inadequate recording facility and bad mobilization planning.Recommendations for future research, is needed good socialization, communication, coordination and cooperation between the government and the public, in order to unify the views in the policy implementation process. In addition, the use value of the e-KTP itself should really be utilized for the distribution of welfare of the people and to improve public access to all public services provided by the government

Model Pemilihan Moda Antara Kendaraan Pribadi Dan Bus Kampus

Peningkatan mahasiswa yang menggunakan kendaraan pribadi dipengaruhi oleh kurangnya ketersediaan angkutan umum dan perbaikan fasilitas parkir kendaraan pribadi oleh kampus. Upaya mengurangi dampak peningkatan kendaraan priadi akibat aktivitas mahasiswa adalah dengan mengoperasikan Bus Kampus. Penelitian ini memiliki beberapa tujuan, yakni : (1) Mengetahui implementasi rute Bus Kampus yang paling potensial untuk diterapkan; (2) Mengetahui tingkat kepentingan dan tingkat kepuasan fasilitas parkir di kampus; (3) Mengetahui harapan pada fasilitas layanan Bus Kampus; dan (4) Mengetahui seberapa besar pengaruh besaran tarif parkir dan atau waktu yang dibutuhkan untuk mendapatkan petak parkir, terhadap kesediaan mahasiswa beralih menggunakan bus kampus. Pengumpulan data dalam penelitian ini menggunakan kuisioner yang dilakukan di beberapa perguruan tinggi negeri dan swasta di Kota Surabaya, dengan total reponden 250 orang. Data yang telah terkumpul selanjutnya diolah dengan menggunakan SPSS. Berdasarkan survei yang telah dilakukan dapat diketahui terdapat 2 rute yang dianggap paling potensial dari 5 rute yakni Surabaya Selatan dan Surabaya Timur. Berdasarkan IPA diketahui ketersedian lahan parkir dan kemudahan mencari petak parkir, merupakan hal yang dianggap penting namun belum mencapai kepuasan yang diharapkan. Kebersihan Bus Kampus merupakan hal penting yang menjadi harapan mahasiswa untuk direalisasikan. Kesedian mahasiswa untuk beralih menggunakan Bus Kampus lebih sensitif akibat Perubahan tarif parkir dibandingkan waktu mencari petak parkir

Measurement of inclusive J/ψ suppression in Au+Au collisions at sNN=200 GeV through the dimuon channel at STAR

J/ψ suppression has long been considered a sensitive signature of the formation of the Quark-Gluon Plasma (QGP) in relativistic heavy-ion collisions. In this letter, we present the first measurement of inclusive J/ψ production at mid-rapidity through the dimuon decay channel in Au+Au collisions at sNN=200 GeV with the STAR experiment. These measurements became possible after the installation of the Muon Telescope Detector was completed in 2014. The J/ψ yields are measured in a wide transverse momentum (pT) range of 0.15 GeV/c to 12 GeV/c from central to peripheral collisions. They extend the kinematic reach of previous measurements at RHIC with improved precision. In the 0-10% most central collisions, the J/ψ yield is suppressed by a factor of approximately 3 for pT>5 GeV/c relative to that in p+p collisions scaled by the number of binary nucleon-nucleon collisions. The J/ψ nuclear modification factor displays little dependence on pT in all centrality bins. Model calculations can qualitatively describe the data, providing further evidence for the color-screening effect experienced by J/ψ mesons in the QGP

Observation of Excess J/ψ Yield at Very Low Transverse Momenta in Au+Au Collisions at sqrt[s_{NN}]=200 GeV and U+U Collisions at sqrt[s_{NN}]=193 GeV.

We report on the first measurements of J/ψ production at very low transverse momentum (p_{T}<0.2  GeV/c) in hadronic Au+Au collisions at sqrt[s_{NN}]=200  GeV and U+U collisions at sqrt[s_{NN}]=193  GeV. Remarkably, the inferred nuclear modification factor of J/ψ at midrapidity in Au+Au (U+U) collisions reaches about 24 (52) for p_{T}<0.05  GeV/c in the 60%-80% collision centrality class. This noteworthy enhancement cannot be explained by hadronic production accompanied by cold and hot medium effects. In addition, the dN/dt distribution of J/ψ for the very low p_{T} range is presented for the first time. The distribution is consistent with that expected from the Au nucleus and shows a hint of interference. Comparison of the measurements to theoretical calculations of coherent production shows that the excess yield can be described reasonably well and reveals a partial disruption of coherent production in semicentral collisions, perhaps due to the violent hadronic interactions. Incorporating theoretical calculations, the results strongly suggest that the dramatic enhancement of J/ψ yield observed at extremely low p_{T} originates from coherent photon-nucleus interactions. In particular, coherently produced J/ψ's in violent hadronic collisions may provide a novel probe of the quark-gluon plasma

Charge-dependent pair correlations relative to a third particle in p + Au and d + Au collisions at RHIC

Quark interactions with topological gluon configurations can induce chirality imbalance and local parity violation in quantum chromodynamics. This can lead to electric charge separation along the strong magnetic field in relativistic heavy-ion collisions – the chiral magnetic effect (CME). We report measurements by the STAR collaboration of a CME-sensitive observable in p+Au and d+Au collisions at 200 GeV, where the CME is not expected, using charge-dependent pair correlations relative to a third particle. We observe strong charge-dependent correlations similar to those measured in heavy-ion collisions. This bears important implications for the interpretation of the heavy-ion data

J/ψ\rm{J}/\psi production at low transverse momentum in p+p and d+Au collisions at sNN\sqrt{s_{NN}} = 200 GeV

We report on the measurement of $\rm{J}/\psi$ production in the dielectron channel at mid-rapidity (|y|<1) in p+p and d+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV from the STAR experiment at the Relativistic Heavy Ion Collider. The transverse momentum $p_{T}$ spectra in p+p for $p_{T}$ < 4 GeV/c and d+Au collisions for $p_{T}$ < 3 GeV/c are presented. These measurements extend the STAR coverage for $\rm{J}/\psi$ production in p+p collisions to low $p_{T}$. The $$ from the measured $\rm{J}/\psi$ invariant cross section in p+p and d+Au collisions are evaluated and compared to similar measurements at other collision energies. The nuclear modification factor for $\rm{J}/\psi$ is extracted as a function of $p_{T}$ and collision centrality in d+Au and compared to model calculations using the modified nuclear Parton Distribution Function and a final-state $\rm{J}/\psi$ nuclear absorption cross section

Observation of charge asymmetry dependence of pion elliptic flow and the possible chiral magnetic wave in heavy-ion collisions

We present measurements of $\pi^-$ and $\pi^+$ elliptic flow, $v_2$, at midrapidity in Au+Au collisions at $\sqrt{s_{_{\rm NN}}} =$ 200, 62.4, 39, 27, 19.6, 11.5 and 7.7 GeV, as a function of event-by-event charge asymmetry, $A_{ch}$, based on data from the STAR experiment at RHIC. We find that $\pi^-$ ($\pi^+$) elliptic flow linearly increases (decreases) with charge asymmetry for most centrality bins at $\sqrt{s_{_{\rm NN}}} = \text{27 GeV}$ and higher. At $\sqrt{s_{_{\rm NN}}} = \text{200 GeV}$, the slope of the difference of $v_2$ between $\pi^-$ and $\pi^+$ as a function of $A_{ch}$ exhibits a centrality dependence, which is qualitatively similar to calculations that incorporate a chiral magnetic wave effect. Similar centrality dependence is also observed at lower energies.Comment: 6 pages, 4 figure
