A Pulse generator based on an Arduino platform for ultrasonic applications Author : Pedro Acevedoa, Mónica Vázqueza, Joel Durána, Rodolfo Petrearcea Source : Physics Procedia 70 ( 2015) 1096 – 1099 Summary of Reported Research : Pulsed methods allow to determine the speed, by measuring the time requiring the pulse to travel through the medium and back. The pulse generator is one of the critical components in an ultrasonic system. Because it is the device that produces the electrical pulses that are applied to the emitter transducer. The most important parameters are frequency, amplitude and power of these electrical pulses, which determine the energy delivered to the ultrasonic transducer. Ultrasonic non-destructive testing applications are often based on pulsed electrical excitation of the piezoelectric transducers (e.g.: PZTs) by means of a single-phase pulse (shock excited) or by means of two-phase waves (burst excited); using to produce these pulses, generators (puls...

Flowchart program "Selamat Datang"              Pada postingan kali ini, saya akan coba membuat sebuah flowchart tentang program sederhana "Selamat Datang" yang sebelumnya sudah dibuat dengan program Delphi 7.              Flowchart dimulai dengan memilih program yang sudah dibuat dengan format .exe. Lalu pilihlah program tersebut. ketika sudah masuk, maka terdapat tulisan "Selamat Datang" dan beberapa tombol diantaranya "Merah", "Putih", dan "Tutup". Ketika tombol "Merah" ditekan, maka tulisan "Selamat Datang" akan berwarna merah. Ketika tombol "Putih" ditekan, maka tulisan "Selamat Datang" akan berubah warna menjadi putih. program akan menutup ketika kita menekan tombol "Tutup" Berikut adalah flowchartnya : 
Fabrication of Hybrid Polymer Solar Cells By Inverted Structure Based on P3HT:PCBMActive Layer Author : Shobih a, *, Rizky Abdillah b, Erlyta Septa Rosa a Source : Jurnal Elektronika dan Telekomunikasi (JET) , Vol. 17, No. 1, Agustus 2017, pp. 13-18 Summary of Reported Research : The making of Fabrication of Hybrid Polymer Solar Cells especially by Inverted Structure Based on P3HT:PCBMActive Layer was different model than the common model now. The common model usually has structure of ITO/PEDOT:PSS/Active Layer will absorb water and hence can easily etch the ITO. Therefore it’s necessary to use another method to avoid these deficiency and obtain more stable polymer solar cells. Based on the measurement results on electrical characteristics of inverted polymer solar cells under 500 W/m2 illumination and AM 1.5 direct filter at room temperature, cell with annealing process of active layer at 110 °C for 10 minutes results in higher cell performance than without annealing, wit...

Flowchart F lowchart atau  Bagan alir  adalah bagan  ( chart ) yang menunjukkan alir  ( flow ) di dalam program atau prosedur sistem secara logika. Bagan alir (flowchart) digunakan terutama untuk alat bantu komunikasi dan untuk dokumentasi.  Pedoman Membuat Flowchart Bila seorang analis dan programmer akan membuat flowchart , ada beberapa petunjuk yang harus diperhatikan, seperti:  Flowchart digambarkan dari halaman atas ke bawah dan dari kiri kekanan. Aktivitas yang digambarkan harus didefinisikan secara hati-hati dan definisi ini harus dapat dimengerti oleh pembacanya. Kapan aktivitas dimulai dan berakhir harus ditentukan secara jelas. Setiap langkah dari aktivitas harus diuraikan dengan menggunakan deskripsi kata kerja Setiap langkah dari aktivitas harus berada pada urutan yang benar. Lingkup dan range dari aktifitas yang sedang digambarkan harus ditelusuri dengan hati-hati. Percabangan-percabangan yang memotong aktivitas yang sedang...
FREQUENCY RESPONSE SERVICES DESIGNED FOR ENERGY STORAGE Author : D.M. Greenwood a , ⇑ , K.Y. Lim b , C. Patsios a , P.F. Lyons a , Y.S. Lim b , P.C. Taylor Source : www.elsevier.com/locate/apenergy Summary of Reported Research : Energy Storage Systems (ESS) are expected to play a significant role in regulating the frequency of future electric power systems. Increased penetration of renewable generation, and reduction in the inertia provided by large synchronous generators, are likely to increase the severity and regularity of frequency events in synchronous AC power systems. By supplying or absorbing power in response to deviations from the nominal frequency and imbalances between supply and demand, the rapid response of ESS will provide a form of stability which cannot be matched by conventional network assets. However, the increased complexity of ESS operational requirements and design specifications introduces challenges when it comes to the realisation of their full po...

TUGAS Pemrograman Bahasa Komputer

ALGORITMA Pendahuluan. Algoritma adalah Sistim kerja komputer memiliki brainware, hardware, dan software. Tanpa salah satu dari ketiga sistim tersebut, komputer tidak akan berguna. Kita akan lebih fokus pada softwarekomputer. Software terbangun atas susunan program (silahkan baca mengenai pengertian program) dan syntax (cara penulisan/pembuatan program). Untuk menyusun program atau  syntax, diperlukannya langkah-langkah yang sistematis dan logis untuk dapat menyelesaikan masalah atau tujuan dalam proses pembuatan suatu software. Maka,Algoritma berperan penting dalam penyusunan program atau syntax  tersebut. Pengertian Algoritma adalah susunan yang logis dan sistematis untuk memecahkan suatu masalah atau untuk mencapai tujuan tertentu. Dalam dunia komputer, Algoritma sangat berperan penting dalam pembangunan suatu software. Dalam dunia sehari-hari, mungkin tanpa kita s...
