SUSTAINABLE CONCEPT FOR BORDER SETTLEMENT AT KAMPUNG ROMO KALISARI SURABAYA

The development of a city tend only to pay attention to the downtown area than in the border area. It can also be seen in the city of Surabaya, particularly in Sub-district Romo Kalisari which is a border kampung between Surabaya and Gresik. Border area is the main access from out of Surabaya to go to other cities and shows the identity of towns, especially to give a first impression on the city. But in Kampung Romo Kalisari, it has not been seen any effort to improve the quality of people.According to the theory used in this study, one of the things that are important in the development of the sustainable city is the economic improvement, particularly on the city's infrastructure. Border area also needs a management that supports the development of sustainable cities. Therefore, this study will provide concrete solutions on improving the city's infrastructure, such as transport and education facilities as well as the trade, which can be applied in the development of border kampungs in the Kampung Romo Kalisari, Surabaya

Pengaruh Pemupukan Nitrogen Dan Sistem Olah Tanah Jangka Panjang Terhadap Pertumbuhan Dan Produksi Padi Gogo (Oryza Sativa L.) Tahun Ke-27 Di Lahan Politeknik Negeri Lampung

Padi gogo merupakan salah satu tanaman pangan yang berpotensi untuk dikembangkan. Pada tahun-tahun mendatang peranan padi gogo dalam penyediaan beras nasional menjadi semakin penting. Hal ini disebabkan karena semakin berkurangnya areal persawahan, sedangkan tingkat pertumbuhan penduduk cukup tinggi. Salah satu upaya dalam meningkatkan pertumbuhan dan produksi padi gogo adalah dengan sistem olah tanah dan pemupukan nitrogen. Tujuan penelitian adalah untuk mengetahui pengaruh pemupukan nitrogen jangka panjang dengan berbagai dosis terhadap pertumbuhan dan produksi padi gogo, mengetahui pengaruh sistem olah tanah jangka panjang terhadap pertumbuhan dan produksi padi gogo, dan mengetahui pengaruh interaksi antara sistem olah tanah dan pemupukan nitrogen jangka panjang dengan berbagai dosis terhadap pertumbuhan dan produksi padi gogo. Penelitian dilakukan di lahan Politeknik Negeri Lampung. Analisis tanaman dilakukan di Laboratorium Ilmu Tanaman Jurusan Agroteknologi Fakultas Pertanian Universitas Lampung. Penelitian dilaksanakan pada bulan Oktober 2014 sampai dengan Maret 2015. Penelitian dilakukan menggunakan Rancangan Acak Kelompok (RAK) yang disusun secara faktorial dengan 4 ulangan. Hasil penelitian menunjukkan bahwa pemupukan nitrogen dengan dosis 100 kg N ha -1 meningkatkan pertumbuhan dibandingkan tanpa pemupukan nitrogen tetapi tidak berbeda dengan pemupukan 50 kg N ha -1 . Pemupukan nitrogen dengan dosis 100 kg N ha -1 meningkatkan produksi padi gogo lebih tinggi dibandingkan tanpa pemupukan nitrogen tetapi tidak berbeda dengan pemupukan 50 kg N ha -1 . Sistem Olah Tanah Intensif mampu meningkatkan tinggi tanaman, dan bobot kering berangkasan lebih tinggi dibandingkan dengan Olah Tanah Konservasi, sedangkan sistem olah tidak memberikan pengaruh terhadap komponen hasil. Interaksi antara pemupukkan nitrogen dan sistem olah tanah terjadi pada variabel pengamatan tinggi tanaman, sedangkan terhadap komponen hasil tidak berpengaruh

Hong-Ou-Mandel interference between independent III-V on silicon waveguide integrated lasers

The versatility of silicon photonic integrated circuits has led to a widespread usage of this platform for quantum information based applications, including Quantum Key Distribution (QKD). However, the integration of simple high repetition rate photon sources is yet to be achieved. The use of weak-coherent pulses (WCPs) could represent a viable solution. For example, Measurement Device Independent QKD (MDI-QKD) envisions the use of WCPs to distill a secret key immune to detector side channel attacks at large distances. Thus, the integration of III-V lasers on silicon waveguides is an interesting prospect for quantum photonics. Here, we report the experimental observation of Hong-Ou-Mandel interference with 46\pm 2% visibility between WCPs generated by two independent III-V on silicon waveguide integrated lasers. This quantum interference effect is at the heart of many applications, including MDI-QKD. Our work represents a substantial first step towards an implementation of MDI-QKD fully integrated in silicon, and could be beneficial for other applications such as standard QKD and novel quantum communication protocols.Comment: 5 pages, 3 figure

Asymptotical photon distributions in the dissipative Dynamical Casimir Effect

Asymptotical formulas for the photon distribution function of a quantum oscillator with time-dependent frequency and damping coefficients, interacting with a thermal reservoir, are derived in the case of a large mean number of quanta. Different regimes of excitation of an initial thermal state with an arbitrary temperature are considered. New formulas are used to predict the statistical properties of the electromagnetic field created in the experiments on the Dynamical Casimir Effect which are now under preparation.Comment: 11 pages, accepted contribution to CEWQO 2009 proceedings (to appear in Physica Scripta

Photon creation from vacuum and interactions engineering in nonstationary circuit QED

We study theoretically the nonstationary circuit QED system in which the artificial atom transition frequency, or the atom-cavity coupling, have a small periodic time modulation, prescribed externally. The system formed by the atom coupled to a single cavity mode is described by the Rabi Hamiltonian. We show that, in the dispersive regime, when the modulation periodicity is tuned to the `resonances', the system dynamics presents the dynamical Casimir effect, resonant Jaynes-Cummings or resonant Anti-Jaynes-Cummings behaviors, and it can be described by the corresponding effective Hamiltonians. In the resonant atom-cavity regime and under the resonant modulation, the dynamics is similar to the one occurring for a stationary two-level atom in a vibrating cavity, and an entangled state with two photons can be created from vacuum. Moreover, we consider the situation in which the atom-cavity coupling, the atomic frequency, or both have a small nonperiodic time modulation, and show that photons can be created from vacuum in the dispersive regime. Therefore, an analog of the dynamical Casimir effect can be simulated in circuit QED, and several photons, as well as entangled states, can be generated from vacuum due to the anti-rotating term in the Rabi Hamiltonian.Comment: 14 pages, 6 figures.

Eye-Safe Solid-State Quasi-CW Raman Laser with Millisecond Pulse Duration

We demonstrate the first quasi-CW (ms-long pulses, pump duty cycle of 10%) end-diode pumped solid state laser generating eye-safe radiation via intracavity Raman conversion. The output power at the first Stokes wavelength (1524 nm) was 250 mW. A theoretical model was applied to analyze the laser system and provide routes for optimization. The possibility of true CW operation was discussed.Comment: Preprint accepted for publication in Optics Communications on Feb 6, 201

Action of the gravitational field on the dynamical Casimir effect

In this paper we analyze the action of the gravitational field on the dynamical Casimir effect. We consider a massless scalar field confined in a cuboid cavity placed in a gravitational field described by a static and diagonal metric. With one of the plane mirrors of the cavity allowed to move, we compute the average number of particles created inside the cavity by means of the Bogoliubov coefficients computed through perturbative expansions. We apply our result to the case of an oscillatory motion of the mirror, assuming a weak gravitational field described by the Schwarzschild metric. The regime of parametric amplification is analyzed in detail, demonstrating that our computed result for the mean number of particles created agrees with specific associated cases in the literature. Our results, obtained in the framework of the perturbation theory, are restricted, under resonant conditions, to a short-time limit.Comment: 2 Figures, comments are welcom
