    Tujuan yang ingin dicapai dalam penulisan ini adalah untuk mengetahui masalah-masalah yang terdapat pada sistem yang sedang berjalan kemudian penulis memberikan usul rancangan sistem yang baru untuk mengatasi masalah-masalah yang di temukan. Rancangan sistem yang baru ini berguna untuk memperlancar dan mempermudah kegiatan-kegiatan di perusahaan baik di masa sekarang maupun masa yang akan datang. Metode yang digunakan dalam pembuatan skripsi ini adalah metode FAST (Framework for the Applications of Sistems Technique). Metode ini merupakan gabungan dari fase demi fase yang ditemui dalam banyak metodologi referensi dan komersil. Dengan kata lain FAST adalah kerangka cerdas yang cukup fleksibel untuk menyediakan tipe-tipe berbeda proyek dan strategi. Sistem Informasi Produksi ini akan mempermudah pencapaian target produksi dan perhitungan penyusutan bahan baku yang ada pada PT. Pinago Utama Palembang

    Is Wave Mechanics consistent with Classical Logic?

    Contrary to a wide-spread commonplace, an exact, ray-based treatment holding for any kind of monochromatic wave-like features (such as diffraction and interference) is provided by the structure itself of the Helmholtz equation. This observation allows to dispel - in apparent violation of the Uncertainty Principle - another commonplace, forbidding an exact, trajectory-based approach to Wave Mechanics.Comment: 13 pages, 4 figure

    HOMES: Holographic Method for Exoplanet Spectroscopy

    The search for habitable exoplanets in the "neighborhood," that is within 10 parsecs (pc),invites new observational techniques, because telescopes available today have significant limitations. For example, gravitational micro-lensing is a deep field method that has little or no utility within 10 pc. Photometry of transits reduces the availability of exoplanets to a probability of approximately a 1%, and fewer than 1 out of 100 earth twins would ever be seen. For the 1% of exoplanets seen in transit, spectra of albedos cannot be taken.Even more limiting, Doppler shift studies are indirect and cannot characterize exoplanets other than by their orbits and masses through stellar radial velocity (RV). Moreover, RV by Doppler shift cannot detect planets in orbits on a plane perpendicular to our line of sight. Astrometry can be used to measure stellar orbital wobble for those exoplanetary systems in the plane perpendicular to our line of sight, as was contemplated for the cancelled NASA SIM mission 1 and rests now with ESA's GAIA2. In either case, the exoplanets detected by stellar RV or astrometry would not be directly observed, so the assumption that the three phases of water could exist does not answer a key question of habitability. Is there water on the exoplanet? Moreover, the discovery of water on an exoplanet in the habitable zone, exciting though it would be, is insufficient to determine just how habitable the exoplanet might possibly be. Like Goldilocks' porridge - there are many other ingredients beyond water alone in a life-sustaining soup.We propose a new species of optical telescope that has as one of its capabilities the high resolution spectrographic characterization of exoplanets on stars within 10 pc of the observatory. To achieve this performance specification, we propose to break with convention by taking advantage of an optical technology unknown until relatively recent times: the hologram. In this Report we show how holograms used in primary and secondary can extract spectrograms from exoplanets at distances reaching 33 light years from our solar system. We describe a notional space telescope using these novel optics that could make its observations in a space deployment scenario

    From Classical to Wave-Mechanical Dynamics

    The time-independent Schroedinger and Klein-Gordon equations - as well as any other Helmholtz-like equation - were recently shown to be associated with exact sets of ray-trajectories (coupled by a "Wave Potential" function encoded in their structure itself) describing any kind of wave-like features, such as diffraction and interference. This property suggests to view Wave Mechanics as a direct, causal and realistic, extension of Classical Mechanics, based on exact trajectories and motion laws of point-like particles "piloted" by de Broglie's matter waves and avoiding the probabilistic content and the wave-packets both of the standard Copenhagen interpretation and of Bohm's theory.Comment: 15 pages, 1 figure.
