Abstract

The aim of this research to investigate citizen’s behaviour in e-Government adoption. The final purpose is to understanding of the public intention at the local government level, the of important things to make e-government service become successful is public acceptance and willingness to use egovernment services. Therefore this study used a model of UTAUT base on the unique problems which consists of six main variables that affect behavioral intention and use behavior, these variables are privacy, trust, performance expectancy, effort expectancy, social influence, and facilitating condition. At the practical level, the research aim to guide e-Government policy decision makers to better plan, design and implemet policies and strategies.

Abstract

A dynamic two-phase imbalance mechanism model of pressurizer in pressurized water reactor (PWR) nuclear power plant was built based on some reasonable simplifications and basic assumptions. The equations of energy and mass conservation are used in obtaining a mathematical model for pressurizer operation. The pressurizer is divided into two regions, steam region and liquid region but not necessary in equilibrium with each other. Considering the influence of the spray flow, surge flow, safety valve and heater, the model of pressurizer pressure control system is established by MATLAB/Simulink in this paper. For the large overshoot, response delay and poor stability exist in the pressurizer pressure control system, an advanced model based on PID control algorithm is proposed. The simulation results were compared between two different data obtained by foreign PWR nuclear power plant simulator. All the compared data are quite similar in simulation result, hence it proves the simulation result quite accurate and yet the mathematical model obtained has proved its working principles successfully.

Abstract

Dalam era teknologi informasi seperti saat ini, hampir seluruh kegiatan transaksi dapat dikerjakan secara otomatis dan elektronik. Perkembangan teknologi menuntut agar sebuah usaha untuk memiliki akses data dan transaksi yang cepat dan tepat agar dapat bersaing. Dengan  pengalaman  lebih  dari  12  tahun  dibidang usaha  Digital  Printing,  CV. Trimatra Unggul Sadaya telah  mampu melayani  berbagai  macam pekerjaan di bidang percetakan, namun dengan pasar yang terus tumbuh juga dengan banyaknya pesaing di lini yang sama, CV. Trimatra Unggul Sadaya harus mampu mempertahankan eksistensinya di bisnis percetakan. Salah satu caranya adalah dengan melakukan inovasi yaitu dengan menambahkan layanan online printing dan mulai berpindah dari bisnis konvensional menjadi e-Business. Pada perancangan e-Business ini penulis menggunakan kuesioner untuk mengetahui keinginan konsumen dan metode QFD untuk mengetahui rincian fitur apa saja yang diinginkan konsumen di dalam web online printing. Untuk mengolah data kuesioner dan uji validitas digunakan software Microsoft Excel. Dalam menentukan parameter pada QFD digunakan dimensi e-Service Quality yang sebelumnya telah di dapat dari kuesioner. Berdasarkan hasil analisis, didapatkan hasil bahwa karakteristik teknis yang menjadi prioritas utama dari konsumen untuk fitur web online printing adalah “kesesuaian informasi”.

Abstract

This paper presents a wireless fire alarm system inpower plant. In the wireless fire alarm system had two sensorslike smoke sensor and temperature sensor. The smoke sensor isdetected the smoke when during the fire disaster happens. Thefire disaster happens the temperature will increase to above 650Call the wire will burnt and will getting smoke around the room.When the smoke sensor and the temperature sensor had signalwill pass through to microcontroller PIC18F4550 and send thedata to computer with using X-bee Pro device. The X-bee Prowill receive signal to computer and show in the Visual Basicabout the status of the room and the temperature at the room.

Abstract

Currently, cloud service providers have used a variety of operational mechanisms to support the company's business processes. Therefore, the services are stored on the company's server, which presents in the form of infrastructure, platform, software, and function. There are several vulnerabilities that have been faced in the implementation such as system failure, natural disasters, human errors, or attacks from unauthorized parties. In addition, the time of unavailability of services can be minimized by doing an LM, in which many servers have been used the containers to behave like a service provider. Actually, its existence replaces the virtual machine that requires more resources although the process only can be done through docker with checkpoint and restore in userspace (CRIU). In this research, LM processes are done to the docker container using CRIU by analyzing the quality of service (QoS), memory, and CPU usage. Thus, the simulation is carried out by establishing the LM using 2 (two) different platforms through scenarios with one and three containers respectively. The performance analysis results aim to examine several indicators in comparison with the achievable result to reduce problems that occurred in the cloud service.
