Dimension-Dependence of the Critical Exponent in Spherically Symmetric Gravitational Collapse
We study the critical behaviour of spherically symmetric scalar field
collapse to black holes in spacetime dimensions other than four. We obtain
reliable values for the scaling exponent in the supercritical region for
dimensions in the range . The critical exponent increases
monotonically to an asymptotic value at large of . The
data is well fit by a simple exponential of the form: .Comment: 5 pages, including 7 figures New version contains more data points,

A People-state Negotiation in a Borderland a Case Study of the Indonesia–Malaysia Frontier in Sebatik Island
This paper aims to show the dynamics of the Indonesian – Malaysian border area in Sebatik Island, East Kalimantan, Indonesia. Take into account as a background is the territorial dispute between Indonesia and Malaysia over the Ligitan and Sipadan Islands which were awarded to Malaysia by the decision of the ICJ (International Court of Justice) in 2002, which was followed by the dispute over the Ambalat sea block in 2005. Sebatik Island is geographically very strategic since it faces the disputed areas. Therefore the concerns of the Indonesian state with regard to the island pertain to issues of nation-state sovereignty and territorial security, which she tries to safeguard through intensive campaigns. Research conducted in Sebatik in 2009 showed how people willingly reinforced the state by incorporating its programs, despite their ambiguous position as people in a border area, which support they used subsequently in negotiating with the state for their own local purpose
Black hole solutions in 2+1 dimensions
We give circularly symmetric solutions for null fluid collapse in
2+1-dimensional Einstein gravity with a cosmological constant. The fluid
pressure and energy density are related by . The
long time limit of the solutions are black holes whose horizon structures
depend on the value of . The solution is the
Banados-Teitelboim-Zanelli black hole metric in the long time static limit,
while the solutions give other, `hairy' black hole metrics in this limit.Comment: 8 pages, RevTeX (to appear in Phys. Rev. D) References to Mann and

Anti-deSitter gravitational collapse
We describe a formalism for studying spherically symmetric collapse of the
massless scalar field in any spacetime dimension, and for any value of the
cosmological constant . The formalism is used for numerical
simulations of gravitational collapse in four spacetime dimensions with
negative . We observe critical behaviour at the onset of black hole
formation, and find that the critical exponent is independent of .Comment: 4 pages, 2 figures, revtex4, version to appear in CQ
JAMALOKE: Bingkai Kecintaan pada Tanah Air dan Kesia-siaan
Novel Jamaloke, adalah sebuah novel yang ditulis oleh anak dari pelaku sejarah Revolusi Indonesia di Surabaya. Novel ini didasarkan pada buku harian ayahnya. Isi novel tidak seluruhnya tentang realitas sesungguhnya dari peristiwa saat revolusi yang terjadi di Surabaya. Dalam konteks ini, pembaca dihadapkan pada persoalan hubungan antara historiografi dan karya sastra (dalam bentuk novel). Historiografi dan karya sastra keduanya merupakan simbol verbal, tapi memiliki perbedaan yang tegas antara keduanya.
Islam dan Kosmopolitanisme Budaya
The Muslim ummah have been dragged into the global culture and have to accept the consequences that emerge thereof. To a certain degree, Muslims were deluded by this global culture and were?as a result?shackled into the seemingly irresolvable problems such as the problem of academic objectivity, the ulama-intellectual dichotomy, identity, terrorism, the so-called minor-major paradigm, and the problem of structural poverty. These problems are interdependent and require an all?embracing solution to resolve them. This paper argues that to speak of a solution on the one hand, and to set up the futuristic strategies to deal with those problems on the other, Muslims should first of all build a solid identity. Four steps are required to build this solid identity. (1) Adhering to the Qur?anic morality as the very foundation for Muslim?s way of life. (2) Appropriating to the maximum the human and natural resources available to the Muslims, which would certainly require them to produce the competent scientists, engineers and so on. (3) Applying the rules of syari?ah to all aspects of Muslim?s life by first of all gaining a proper understanding about the true teaching of Islam and the real spirit that underlies it. (4) Establishing and maintaining international relationships with foreign countries as well as with other cultures and civilizations. The implication of Islam being a religion of compassion is that it should be built upon understanding and tolerance. Islam advocates the principle of mutual interest and is willing to achieve a better future for all human being
General covariance, and supersymmetry without supersymmetry
An unusual four-dimensional generally covariant and supersymmetric SU(2)
gauge theory is described. The theory has propagating degrees of freedom, and
is invariant under a local (left-handed) chiral supersymmetry, which is half
the supersymmetry of supergravity. The Hamiltonian 3+1 decomposition of the
theory reveals the remarkable feature that the local supersymmetry is a
consequence of Yang-Mills symmetry, in a manner reminiscent of how general
coordinate invariance in Chern-Simons theory is a consequence of Yang-Mills
symmetry. It is possible to write down an infinite number of conserved
currents, which strongly suggests that the theory is classically integrable. A
possible scheme for non-perturbative quantization is outlined. This utilizes
ideas that have been developed and applied recently to the problem of
quantizing gravity.Comment: 17 pages, RevTeX, two minor errors correcte
Aplikasi Pendeteksi Dini Kanker Serviks Berbasis Android
Cervical cancer is the growth of a group of abnormal cells in the cervix (mouth of the womb). The lack of knowledge in diagnosing women against cervical cancer is around 60% - 77%. Lack of diagnostic knowledge about cervical cancer symptoms so that many women do not know the symptoms of cervical cancer and have two possibilities whether it is cervical cancer symptoms or symptoms of other diseases. The purpose of the study was to design an Android-based cervical cancer early detection application to monitor cervical cancer early in helping women diagnose independently. The R&D (Research and Development) research method functions to generate, develop and test the effectiveness of the product (an android-based cervical cancer early detection application) and the forward chaining method functions in making decisions based on the facts that are inputted so as to produce conclusions. home menu, diagnoses, diagnostic results and profiles, starting with the user clicking the diagnosis menu in selecting the symptoms he is experiencing, then the user clicking the diagnostic results menu to see the results of the symptoms that have been diagnosed and have 4 criteria, namely cervical cancer stage 1, cervical cancer stage 2, cervical cancer stage 3 and cervical cancer stage 4. The conclusion of the application where the functional input and output runs well in accordance with the basic concepts that have been made and can be implemented.Kanker serviks merupakan pertumbuhan dari suatu kelompok sel yang tidak normal pada serviks (mulut rahim). Minimnya pengetahuan mendiagnosa yang dimiliki wanita terhadap kanker serviks sekitar 60% - 77%. Kurangnya pengetahuan diagnosa tentang gejala kanker serviks sehingga banyak perempuan tidak mengetahui gejala kanker serviks dan memiliki dua kemungkinan apakah itu gejala kanker serviks atau gejala penyakit lainnya. Tujuan penelitian merancang aplikasi pendeteksi dini kanker serviks berbasis android guna memantau secara dini penyakit kanker serviks dalam membantu perempuan mendiagnosa secara mandiri. Metode penelitian R&D (Research and Development) berfungsi menghasilkan, mengembangkan serta menguji keefektifan produk (aplikasi pendeteksi dini kanker serviks berbasis android) dan metode forward chaining berfungsi dalam pengambilan keputusan berdasarkan fakta yang di input sehingga menghasilkan kesimpulan. Hasil pengujian aplikasi terdapat 4 menu utama yaitu menu home, diagnosa, hasil diagnosa serta profil, dimulai dengan pengguna mengklik menu diagnosa dalam memilih gejala yang dialaminya, kemudian pengguna mengklik menu hasil diagnosa untuk melihat hasil dari gejala yang telah diagnosanya dan memiliki 4 kriteria yaitu kanker serviks stadium 1, kanker serviks stadium 2, kanker serviks stadium 3 dan kanker serviks stadium 4. Kesimpulan aplikasi dimana fungsional input dan output berjalan dengan dengan baik sesuai dengan konsep dasar yang telah dibuat serta dapat diimplementasikan
