RANCANGAN APLIKASI INTEROPERABILITAS SISTEM INFORMASI INTER DEPARTEMEN
No full textRancangan aplikasi layanan untuk interoperabilitas sistem informasi instansi pemerintah ini direncanakan dapat menghubungkan beberapa sistem informasi pemerintahan yang berbeda platform (baik dari sisi Sistem Operasi, Bahasa Pemrograman maupun Databasenya), sehingga antar sistem informasi tersebut bisa saling tukar data satu dengan yang lainnya melalui layanan berbasis web/internet menggunakan konsep web service. Rancangan aplikasi interoperabilitas yang dibuat dipergunakan untuk menghubungkan beberapa instansi yaitu : Kependudukan (Depdagri), Kesehatan (Depkses), Bappenas dan BPS (Badan Pusat Statistik) agar bisa saling menukar data dan informasi. Masing-masing instansi dapat menggunakan aplikasi ini untuk mengirim data mereka sesuai dengan format standar yang telah ditentukan yaitu format xml dan dikirimkan ke sebuah server repositori nasional. Dari server inilah instansi yang lain dapat saling melihat data dari instansi lain dan menggunakannya sesuai kebutuhan. Dalam penelitian kali ini diajukan rancangan aplikasi interoperabilitas serta diujicobakan menggunakan data yang berasal dari empat instansi diatas. Aplikasi yang dihasilkan terdiri dari tiga macam aplikasi yaitu : aplikasi xmlCreator, aplikasi xmlReader dan Sistem Informasi yang berbentuk web. Dalam sistem informasi selain disajikan menu informasi data dari masing-masing instansi juga disajikan daftar file xml dan web service
Penyelesaian Jalur Terpendek dengan menggunakan Algoritma Flood Fill pada Line Maze
No full textFlood fill adalah metode yang umum digunakan untuk menyelesaikan maze dalam bentuk dinding . dan sangat jarang digunakan untuk menyelesaikan maze dalam bentuk garis. Pada paper ini diimplementasikan algoritma flood fill pada line follower robot untuk melakukan pencarian jalur dari tempat awal menuju tempat tujuan dalam suatu lingkungan terkontrol berupa maze dalam bentuk garis. Algoritma ini bekerja dengan mengisi sebuah area dengan penanda tertentu. Pada tahap awal algoritma ini akan membagi suatu area, menjadi sub-sub area yang lebih kecil, yang dapat didefinisikan sebagai suatu matrik. Kemudian mengisi sub-sub area tersebut dengan sebuah nilai awal, dimana nilai ini merupakan perhitungan awal untuk jarak dari masing-masing area tersebut dari titik tujuan. Nilai ini akan di-update sesuai dengan kondisi line maze yang dihadapi, sehingga nilai dari tiap area ini akan sesuai dengan kondisi lapangan (maze) yang dihadapi. Pada praktek di line follower robot secara langsung algoritma ini telah dapat berjalan dengan tingkat keberhasilan 80%. Manfaat dari penelitian kali ini adalah pengembangan kecerdasan buatan dalam bidang robotika, khususnya dalam hal maze maping dan path finding pada line follower robot. Kata kunci—line follower robot, maze maping, flood fill, update, path findin

No full textMonitoring of electrical energy parameter, such as voltage, current, active power, reactive power, power factor, and frequency, shall be done to guarantee quality of services for electric energy users. Energy management must be done to support decision making concerning to energy efficiency and cost, particularly for commercial building. Such effort is often called as demand side management. This research is aimed at developing a real-time measurement system which is capable of monitoring electrical energy parameter for commercial buildings. Real-time monitoring system developed in this study employs an ADC hardware named Multifunction NI DAQ 6008 (maximum 8 analog input, 12 bits, 10 kS/s) and LabVIEW 8.2 software. Both hardware and software manufactured by National Instruments are used to carry out data accuisition at the remote terminal unit (RTU). Aqcuired data is sent to the database server by LogSender application program. Here, JRealTimeChartView application developed in Java programming language is embedded into HTML tags to make the real-time presentation of the acquired data in graph format on the web page.Data saved in the database server is then processed to make daily, monthly, and yearly reports. The reports are presented on the web using an application named GrafikBebanBesaran which is also embedded into HTML tags. Data acquisition of voltage at RTU is done by reducing voltage from AC 220 volt to AC 3 volt used step down transformer and hereinafter is put into analog input at NI DAQ 6008, while for data acquisition of electric current is used by Current Transformer 50/5A. Induction current yielded by CT is put into analog input at NI DAQ 6008. Obtained data, calibrated to become data like the original data using software LabVIEW. This research yields measurement data of electrical energy parameters saved at a server database. This database contains data of electrical energy parameters sent from RTU.

Micro Traffic Simulation with Unpredictable Disturbance Based on Monte Carlo Simulation: Effectiveness of the proposed agent cars for minimizing evacuation time in the case of Sidoarjo hot mudflow disaster
Get PDFMonte Carlo simulation of micro traffic with unpredictable disturbance is conducted for the realistic situation of evacuation from Sidoarjo hot mudflow disaster. We concern to the main artery road very close to high dike for prevention of spillover the hot mudflow. This road is major traffic connection with surrounding districts and disaster areas and has a heavy traffic. The mud volcano remains with a high flow rates. The important matter when the mud containment walls broken and the mud flows on the road is how does the vehicle can be evacuated from the disaster occurred areas through suffered roads. This study presents evacuation simulation of vehicles in surrounding affected road using an agent-based model. We estimated the time required for evacuation and the number of victim toward the traffic condition (probability of vehicle density) and the driving behavior (probability of lane changing). Both of them are evaluated and compared between with/without agent cars

RANCANG BANGUN SISTEM PENGUKURAN ARUS BERBASIS MIKROKONTROLLER ATmega 8535
No full textIn general, the measurement of current in a circuit using amperemeter. However, current measurements with amperemeter weakness was not able to display the form of a measurable current signal. In this project created a tool that can measure the flow and display of the measured current signal into a PC-based Microcontroller ATmega 8535. This design uses Hall effect sensors UGN3503 as current sensors, Hall effect sensor UGN3503 can measure the magnetic field generated from the teraliri wire electric currents. Sensor output voltage is equal to the electric current flowing in the wire. The working principle of the flow measuring device based on PC (Personal Computer) is the current detection circuit that is the Hall effect sensor UGN3503 used to measure the current flowing in a circuit then the current magnitude is converted into digital quantities by using 10-bit ADC which is owned by the microcontroller ATMega8535. Scale digital output from ADC is sent to a PC via the serial port and the PC data is converted into a form of signal. The existence of such forms results measurable current signal can then be easier in view of current changes occur in the series and can instantly save the data flow changes into the computer
