Rancangan Jaringan Sistem Mobile Pulsa Listrik Prabayar

Sistem meteran digital listrik pra bayar yang ada saat ini mempunyai kelemahan dari sisi kontrol maupun perilaku. Pengisian harus dilakukan pada meteran, sehingga bila rumah sedang ditinggal penghuninya dalam waktu lama maka listrik akan padam sampai dengan penghuni rumah datang dan mengisi ulang. Sistem meteran juga tidak dilengkapi dengan catatan penggunaan sehingga belum bisa menjadi alat analisis bagi pengguna untuk melakukan penghematan. Diperlukan sebuah sistem agar pelanggan listrik prabayar mampu mengontrol pulsa listrik (token) dimanapun mereka berada. Sistem ini dibangun menggunakan aristektur GSM yang sudah tersedia dengan memanfaatkan fitur SMS. Langkah pengembangan sistem dimulai dengan perancangan mikrokontroler untuk membaca data meteran, instalasi modul program di mikrokontroler untuk dapat menghitung penggunaan daya dan pengiriman data via sms. Pembuatan sistem berbasis mobile untuk mengolah data di handphone pelanggan sehingga jadilah sebuah sistem yang interaktif dimana pelanggan dapat setiap waktu terhubung dan mengupdate informasi dari meteran digital listrik prabayar

Monitoring Low-Cycle Fatigue Material-Degradation by Ultrasonic Methods

Any system consisting of structural material often undergoes fatigue, which is caused by dynamic load cycle. As a structural system, nuclear power plant is very likely to have low-cycle fatigue at many of its components. Taking into account the importance of monitoring low-cycle fatigue on structural components to prevent them from getting failure, the authors have conducted a work to monitor material degradation caused by low-cycle fatigue by using ultrasonic method. An alloy of Cu-40Zn was used as a test specimen. Ultrasonic water immersion procedure was employed in this ultrasonic test. The probe used is a focusing type and has frequency as high as 15 MHz. The specimen area tested is in the middle part divided into 14 points × 23 points. The results, which were frequency spectrums, were analyzed using two parameters: frequency spectrum peak intensity and attenuation function gradient. The analysis indicates that peak intensity increases at the beginning of load cycle and then decreases. Meanwhile, gradient of attenuation function is lower at the beginning of fatigue process, and then consistently gets higher. It concludes that low-fatigue material degradation can be monitored by using ultrasonic method.Received: 20 November 2009; Revised: 31 August 2010; Accepted: 31 August 201

Pembuatan Video Klip “Terbang” Oleh “Flourescent Band” Dengan Menggunakan Teknik Stop Motion

Development of music in Indonesia has experienced arguably the most significant advances, people are now getting to know a wide range of musical genres, and one of the most popular genres of music in Indonesia at the moment is kind of alternative pop music. Indonesian pop music in mushrooming as the presence of bands that carry these streams, as well as by "flourescent band", a band from the city of Yogyakarta, which stands on the basis of friendship and common hobby in the field of music, making the band think to try to create an homage to pop music arranger alternative with a slightly different color, as well as a design of a video clip with a different concept of course.The title track will be used in the design of a video clip entitled "Terbang" by Flourescent band. The design is intended as a video clip of implementation especially video-making skills using stop motion animation techniques, and also will serve as a media promotion of the band "Flourescent" itself.In the design of this video will be using the merger between videography techniques, stop motion and motion graphics techniques to the results generated from the design of the video clip will be more unique and interesting

Penerapan Change Management untuk Peningkatan Proses Bisnis dalam Meraih Keunggulan Kompetitif Organisasi

Lingkungan bisnis merupakan faktor yang sangat berpengaruh pada proses bisnis sebuah organisasi, Perubahan yang terjadi pada lingkungan bisnis harus dapat direspon secara positif oleh organisasi, supaya organisasi tersebut dapat bertahan hidup dan meraih keunggulan kompetitif. Change management merupakan serangkaian proses yang digunakan untuk memastikan bahwa Perubahan yang signifikan dapat dilakukan secara terkontrol dan sistematis, untuk mengatasi resistensi terhadap Perubahan dalam rangka meningkatkan keterlibatan dan pencapaian tujuan organisasi untuk melakukan transformasi yang efektif. Pada makalah ini akan dibahas penerapan change management dengan pendekatan manajemen proyek Perubahan yang mengadopsi dari model yang dikemukakan John P. Kotter dan William Bridges, kajian ini akan memberikan pemahaman tentang pengetahuan secara teori dan menggabungkannya antara practical tool dan metodologi manajemen proyek dalam mengelola proses Perubahan yang kompleks. Untuk melengkapi kajian dari penelitian, pada makalah ini dilengkapi dengan pembahasan sebuah studi kasus

Perencanaan Struktur Gedung Kuliah Lima Lantai Di Kota Semarang (Dengan Menggunakan Metode Srpmk

The structural of college building planned in Semarang, which the structure of the building is designed by using the Special Moment Resisting Frame System (SMRFS) based on ”Indonesian Concrete Code (SNI 03-2847-2002)”, while the analysis of earthquake load uses response spectrum method based on “Indonesian Seismic Code (SNI 03-1726-2010)”. The design structural of these college building using“Capacity Design” concept. As for using this concept has purpose what if strong earthquake happens, that cause forms plastic hinge on structural elements which is desired appeared on the beams. To guarantee plastic hinge happens on the beams, so the coloumns must be designed stronger than the beams (Strong Column Weak Beam Concept). The analysis of the structure is using SAP2000 computer program version 14. As the result of calculations showed that structural element of building is safe based on analyze

Perencanaan Struktur Gedung Rumah Sakit Islam Gigi dan Mulut Rsi Sultan Agung Semarang

Perencanaan Struktur Gedung Rumah Sakit Islam Gigi dan Mulut Sultan Agung Semarang ini dilakukan untuk mengetahui dimensi struktur utama apabila pembangunan gedung dilakukan dengan menggunakan metode konvensional. Gedung Rumah Sakit Islam Gigi dan Mulut Sultan Agung Semarang direncanakan dapat menjadi struktur tahan gempa. Pada perencanaan struktur tahan gempa diperlukan analisis beban gempa, pada gedung RSI ini diggunakan metode respon spektrum yang merupakan analisis dinamik. Berdasarkan Kriteria Desain Seismik (KDS) gedung RSI ini menggunakan Sistem Rangka Pemikul Momen Khusus (SRPMK) karena mempunyai tipe D.

Perencanaan Struktur Rumah Sakit Islam Sultan Agung Semarang

Structure design of Sultan Agung Islamic Hospital designed by SNI 03‒2847‒2002 and SNI 1726‒2012, where analysis of earthquake load structure the building made by Spectrum Analysis Method of Dynamic Response. The analysis dynamic response spectrum of building structure is included in Seismic Design Criteria of type D with high seismicity level of risk, so that the planning system is the method used by the building frame structure configuration bearers Special Moment Frame System(Sway‒special). Sway‒special system is designed to be the building does not collapse during an earthquake in excess of the earthquake that has been designed, therefore Sway‒special the model is designed to qualify the strong column weak beam, where the columns are designed to withstand the beam when the beam undergo plastic hinge. Additionally joint should also be designed to prevent well collapse when the beam experiencing first plastic hinge. The structure design of Sultan Agung Islamic Hospital has asymmetrical shape configuration , so when an earthquake the building will undergo rotational stiffness caused by the center of mass and the center of rigidity is not located in a single point, so that should be dilated so that the center of mass and center of stiffness becomes coincide
