Studi Perencanaan Kebutuhan Instalasi Listrik di Rumah Sakit Umum Daerah dr. Rubini Mempawah

Rumah Sakit Umum Daerah dr. Rubini Mempawah sedang merencanakan pembangunan gedung baru. Bangunan Rumah Sakit Umum Daerah dr. Rubini Mempawah ini akan direncanakan berjumlah 6 gedung. Untuk membangun Rumah Sakit Umum Daerah dr. Rubini Mempawah ini diperlukan perencanaan instalasi listrik yang merupakan bagian pada tahap awal pekerjaan. Dengan adanya perencanaan ini dapat membuat sistem instalasi listrik agar beroperasi dengan baik dan pengadaan sarana serta prasarana fisik dan non-fisik juga dapat tertata dengan baik. Dalam merencanakan instalasi ini menggunakan metode studi literatur, observasi, diskriftif analitik dan metode lumen. Pada tahap perencanaannya dilakukan beberapa perhitungan yaitu menghitung kebutuhan iluminasi penerangan, kapasitas tata udara, luas penampang penghantar, rating arus pengaman serta membuat line diagram dan menghitung rincian anggaran biaya. Perencanaan instalasi listrik ini direncanakan sesuai dengan  Standar Nasional Indonesia, yang mengacu pada Peraturan Menteri Kesehatan Republik Indonesia Nomor 24 Tahun 2016 dan Peraturan Umum Instalasi Listrik 2011. Berdasarkan hasil perhitungan  dan analisa diperoleh besar daya untuk memenuhi seluruh kebutuhan beban listrik yaitu sebesar 1547025 Watt dan biaya total seluruh pekerjaan yaitu sebesar Rp11.052.230.086

Pengaruh Metode Pembelajaran Inquiry Berbasis Visualisasi Materi Larutan Elektrolit dan Nonelektrolit di Kelas X IPA SMA Negeri 1 Kawangkoan

The purpose of this study is to examine the effect of visualization-based inquiry learning methods on student learning outcomes in electrolyte and non-electrolyte solution material. This research was conducted in Kawangkoan 1 Public High School, in the even semester X IPA students, 2018/2019 academic year. Class X IPA students 1 (n = 31) as the experimental class and class X IPA 2 (n = 32) as the control class. The test used in this study statistical t test with significance level α = 0.05 with the testing criteriat> ttable then H0 is rejected and H1 accepted. The results obtained in this test obtained tcount 5.25> ttable 1.670. This test is done not to improve student learning outcomes beyond the minimum standard of completeness criteria in school but this testing is only to see the effect of visualization based inquiry learning methods on student learning outcomes. Based on the results obtained it can be concluded that there are differences in student learning outcomes applied with conventional learning models (control class) and visualization based inquiry learning methods (experimental class

Phase Transition and Symmetry Breaking in the Minority Game

We show that the Minority Game, a model of interacting heterogeneous agents, can be described as a spin systems and it displays a phase transition between a symmetric phase and a symmetry broken phase where the games outcome is predicable. As a result a ``spontaneous magnetization'' arises in the spin formalism.Comment: 4 pages, 2 figures, submitted to PRE/Rapid Communications Major revision of the tex

Effects of impulsive noise on marine mammals : investigating range-dependent risk

This work was funded as part of the Department of Energy and Climate Change's Offshore Energy Strategic Environmental Assessment programme, with additional resources from the National Capability funding from the Natural Environment Research Council to the Sea Mammal Research Unit (grant no. SMRU1001). Recordings of piling and seismic noise from the Moray Firth were collected with the support of the Department of Energy and Climate Change, Scottish Government, Oil and Gas UK Ltd., COWRIE, EU DOWNVInD project, Talisman Energy (UK) Ltd. and Scottish & Southern Energy. Thanks also to Helen Bailey and Keith Needham for making field recordings, Francesca Marubini for comments and suggestions on drafts of the manuscript, and to Stephen Robinson at the National Physics Laboratory and Douglas Gillespie at the Sea Mammal Research Unit for discussions and guidance about acoustic analyses.Peer reviewedPublisher PD

Acoustic Probing of the Jamming Transition in an Unconsolidated Granular Medium

Experiments with acoustic waves guided along the mechanically free surface of an unconsolidated granular packed structure provide information on the elasticity of granular media at very low pressures that are naturally controlled by the gravitational acceleration and the depth beneath the surface. Comparison of the determined dispersion relations for guided surface acoustic modes with a theoretical model reveals the dependencies of the elastic moduli of the granular medium on pressure. The experiments confirm recent theoretical predictions that relaxation of the disordered granular packing through non-affine motion leads to a peculiar scaling of shear rigidity with pressure near the jamming transition corresponding to zero pressure. Unexpectedly, and in disagreement with the most of the available theories, the bulk modulus depends on pressure in a very similar way to the shear modulus

Collaborative development of diffraction-limited beamline optical systems at US DOE light sources

An ongoing collaboration among four US Department of Energy (DOE) National Laboratories has demonstrated key technology prototypes and software modeling tools required for new high-coherent flux beamline optical systems. New free electron laser (FEL) and diffraction-limited storage ring (DLSR) light sources demand wavefront preservation from source to sample to achieve and maintain optimal performance. Fine wavefront control was achieved using a novel, roomtemperature cooled mirror system called REAL (resistive element adjustable length) that combines cooling with applied, spatially variable auxiliary heating. Single-grating shearing interferometry (also called Talbot interferometry) and Hartmann wavefront sensors were developed and used for optical characterization and alignment on several beamlines, across a range of photon energies. Demonstrations of non-invasive hard x-ray wavefront sensing were performed using a thin diamond single-crystal as a beamsplitter

Infantile spasms (West syndrome): update and resources for pediatricians and providers to share with parents

Background Infantile spasms (IS; West syndrome) is a severe form of encephalopathy that typically affects infants younger than 2 years old. Pediatricians, pediatric neurologists, and other pediatric health care providers are all potentially key early contacts for families who have an infant with IS. The objective of this article is to assist pediatric health care providers in the detection of the disease and in the counseling and guidance of families who have an infant with IS. Methods Treatment guidelines, consensus reports, and original research studies are reviewed to provide an update regarding the diagnosis and treatment of infants with IS. Web sites were searched for educational and supportive resource content relevant to providers and families of patients with IS. Results Early detection of IS and pediatrician referral to a pediatric neurologist for further evaluation and initiation of treatment may improve prognosis. Family education and the establishment of a multidisciplinary continuum of care are important components of care for the majority of patients with IS. The focus of the continuum of care varies across diagnosis, initiation of treatment, and short- and long-term needs. Several on-line educational and supportive resources for families and caregivers of patients with IS were identified. Conclusions Given the possibility of poor developmental outcomes in IS, including the emergence of other seizure disorders and cognitive and developmental problems, early recognition, referral, and treatment of IS are important for optimal patient outcomes. Dissemination of and access to educational and supportive resources for families and caregivers across the lifespan of the child with IS is an urgent need. Pediatric health care providers are well positioned to address these needs
