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

A dynamic two-phase imbalance mechanism model ofpressurizer in pressurized water reactor (PWR) nuclear powerplant was built based on some reasonable simplifications andbasic assumptions. The equations of energy and massconservation are used in obtaining a mathematical model forpressurizer operation. The pressurizer is divided into tworegions, steam region and liquid region but not necessary inequilibrium with each other. Considering the influence of thespray flow, surge flow, safety valve and heater, the model ofpressurizer pressure control system is established byMATLAB/Simulink in this paper. For the large overshoot,response delay and poor stability exist in the pressurizer pressurecontrol system, an advanced model based on PID controlalgorithm is proposed. The simulation results were comparedbetween two different data obtained by foreign PWR nuclearpower plant simulator. All the compared data are quite similar insimulation result, hence it proves the simulation result quiteaccurate and yet the mathematical model obtained has proved itsworking principles successfully.

Abstract

Abstrak PT. Karya kita adalah sebuah perusahaan yang bergerak dibidang percetakan. Tingginya akan pemesanan buku, mendorong perusahaan untuk melakukan inovasi dalam proses pembuatan buku. Dilihat dari alur produksinya bahwa terdapat proses yang masih menggunakan cara manual, yaitu pada proses pengukuran buku dengan menggunakan penggaris. Berdasarkan permasalahan diatas, penulis merancang alat bantu pada proses pengukuran buku untuk mengurangi waktu proses pengukuran buku dengan menggunakan Framework Mechanical Design dan Tools-nya mengadopsi dari Ulrich-Eppinger.Hasil yang didapat dari tahapan Framework Mechanical Desgin berupa spesifikasi dari rancangan alat bantu yang akan dibuat, yaitu dimensi dari alat bantu disesuaikan dengan ukuran SNI dan batas toleransi yang telah ditetapkan, alat bantu di desain menumpuk dari mulai ukuran terkecil (A5) hingga ukuran (A4), alat bantu dapat ditempatkan di atas meja, dan mekanisme alat bantu ini rotating yang artinya dapat diputar. Kata Kunci: Framework Mechanical Design, Spesifikasi teknis, Ulrich-Eppinger
