PERANCANGAN DAN PEMBUATAN LAMPU DARURAT UNTUK DAERAH RAWAN BENCANA ALAM
Full text linkPembuatan lampu darurat sangat diperlukan karena kita harus mengantisipasi keadaandarurat misalnya padamnya lampu listrik. Kebutuhan penerangan yang dibutuhkan adalahpenerangan sekitar 40 watt lampu tabung, namun pembuatan lampu darurat ini bisa memenuhipenerangan yang sama tetapi daya yang digunakan bisa sepertiganya. Selain dayanya bisaberkurang menjadi sepertiganya keuntungan lainnya adalah bentuknya kecil sangat ringan dijinjingdan dari segi charge dayanya bisa dengan cara diputar secara manual sehingga tidak tergantungdari daya PLN yang tidak bisa kita andalkan saat terjadi bencana
AUTOMATIC TRANSFER SWITCH PANEL IN PLN ELECTRICITY AND POWER INVERTER 2000 WATT
Full text linkIn line with the development of science and technology today, especially in the field of electricity brought many changes in the use of electricity. Electricity is currently needed both industrial and non-industrial. Electricity needs are currently provided by PLN as the main power source. The flow of electricity from the electricity grid is not always continuous in its distribution, one day there must be a blackout that may be caused by interference with the transmission system or distribution system. To anticipate this outage, it is necessary to design an automatic control called an automatic transfer switch and to prepare a backup source, a 2000-watt power inverter. Automatic transfer switch is electrical equipment that functions as a controller of the process of switching the PLN electricity supply to the inverter power supply or vice versa automatically. In the operation of this automatic transfer switch can be operated manually and automatically. Where is in automatic mode, if there is a power outage on PLN this tool is useful for turning on and connecting the power inverter to the load automatically. When PLN revives, this tool will transfer the power source to the load from the power inverter to the PLN electricity. At this time technological advances are developing very rapidly, technology is an inspiration so that life in the world becomes lighter, easier and practical
SISTEM MONITORING KWH METER BERBASIS PC DILENGKAPI DENGAN PROGRAM PENGHITUNG BIAYA LISTRIK
Full text linkEnergi listrik merupakan energi yang sangat vital dalam operasional perusahaan maupunrumah tangga. Hampir semua peralatan dan sumber penerangan yang digunakan berasal darienergi listrik. Namun dalam pemakaiannya banyak dikeluhkan adanya ketidak-efisiensian energilistrik ini. Hal ini terbukti dari membengkaknya tagihan listrik yang harus dibayarkan perbulannya.Terlebih apabila ini terjadi dilingkungan kantor atau perusahaan maka akan mengakibatkananggaran biaya yang cukup besar. Untuk mengefisiensikan pemakaian listrik, maka perludilakukan manajemen pemakaian listrik untuk penghematan energi. Ada tiga rumusan masalah dalam penelitian ini yaitu, bagaimana merancang prototypesystem monitoring kWh meter berbasis PC, bagaimana program dapat menghitung biaya listrikuntuk mengetahui berapa rupiah yang di keluarkan perhari, bagaimana membuat bentuk desainsystem monitoring kWh meter berbasis PC yang aplikatif bagi masyarakat. Tujuan dari penelitianini adalah membuat program untuk memperoleh hasil perancangan dari Sistem monitoring kWhmeter berbasis PC dilengkapi dengan program penghitung biaya listrik. Penulis menggunakan metode analisis statistik diskriptif yaitu statistik yang digunakanuntuk menganalisis data dengan cara mendeskripsikan atau menggambarkan data yang telahterkumpul sebagaimana adanya atau mendiskripsikan data-data yang diproses dari hasilpengamatan, percobaan dan pengukuran kejadian yang di teliti, selain itu yang termasuk dalamstatistik deskriptif antara lain yaitu penyajian data melalui tabel. Setelah melakukan analisis datapenulis menyimpulkan bahwa telah berhasil dirancang sebuah alat Monitoring kWh meter berbasisPC di lengkapi dengan biaya penghitung biaya listrik yang memudahkan kita memanagementlistrik di suatu lokasi
SAFEGUARDING MOTORIZED VEHICLES WITH ARM VIBRATORS USING ULTRASONIC SENSORS AND BLUETOOTH
Full text linkSafeguarding motorized vehicleswith arm vibrators using ultrasonic sensorsand Bluetooth is an innovation in safetysystems on motorized vehicles (Motorbikes).This tool uses a proximity sensor and armvibrator, which this tool will work if themotor vehicle (motorcycle) is too close to theobject in front of it. When the sensor hasdetected an object, the vibrator willautomatically vibrate the arm. When thevibrator vibrates, that will be a sign that thedriver is too close to the vehicle in front ofhim, so the driver will maintain a safedistance from other vehicles in front. Theobjectives of this research activity includeknowing the concept of developing a safetysystem on motorized vehicles that can preventaccidents, when motorists are negligent incontrolling the speed of their vehicles on thehighway

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
