Abstract

DEVELOPMENT OF BRACHYTHERAPY MEDIUM DOSERATE . Brachytherapy has proven to be an effective treatment for different types of cancers and it become a common treatment modality in most radiotherapy clinics. PRPN has had experience in development of Low Dose Rate Brachytherapy for cervic cancer treatment. However the treatment process using LDR device needs 5 hours which makes the patient feel uncomfort. Therefore PRPN develops Medium Dose Rate Brachytherapy with radiation activity not more than 5 Currie. By using this system the expsure time will be shorter. The project is divided into two stages. Purchasing of TPS software and TDS design are held in 2010, and the construction will be in 2011. PEREKAYASAAN BRACHYTHERAPY MEDIUM DOSERATE. Brachytherapy telah menjadi suatu pengobatan yang efektif dari berbagai jenis kanker dan merupakan suatu modalitas pengobatan yang umum pada kebanyakan kilinik-klinik radiotherapi. PRPN telah memiliki pengalaman dalam pengembangan brachytherapy tipe Low Dose Rate (LDR)untuk terapi kanker servik (leher rahim). Namum proses penyinaran menggunakan tipe LDR dibutuhkan waktu lebih dari 5 jam sehingga kurang nyaman bagi pasien. Oleh karena itu PRPN mengembangkan brachytherapy tipe Medium Dose rate (MDR) dengan aktivitas sumber tidak lebih dari 5 Currie. Dengan sistem ini, diharapkan waktu penyinaran menjadi lebih pendek. Kegiatan ini dibagi menjadi dua tahun. Tahun 2010 terdiri dari pengadaan perangkat lunak TPS dan desain Treatment Delivery System (TDS) dan konstruksi tahun 2011.

Abstract

DESIGN AND CONSTRUCTION OF STEPPER MOTOR CONTROLER FOR BRACHY-THERAPY EQUIPMENT. Based on a microcontroller, a stepper motor controller for brachy-theraphy equipment has been designed and prototyped. The embedded control program routine and its other associated routines enable the microcontroller to generate required pulses via external commands for stepper motor based position control. The controller receives ASCII text command via a serial port. The constructed algorithm implements the widely used method that allows motor to rotate in three phases, i.e: acceleration, constant speed, and deceleration.   RANCANG BANGUN PENGATUR GERAK STEPPER MOTOR UNTUK PERALATAN BRAKITERAPI. Telah dilakukan perekayasaan sistem pengatur gerak stepper motor untuk brakiterapi dengan menggunakan mikrokontroler. Kode program subrutin pengaturan gerak dan subrutin yang berkaitan ditanamkan agar mikrokontroler dapat membangkitkan pulsa yang diperlukan untuk melakukan kontrol posisi berbasis stepper motor dengan perintah eksternal. Perintah pengaturan berupa teks ASCII diberikan melalui saluran komunikasi serial. Algoritma umum dipakai dalam pengaturan gerak motor, yaitu terdiri dari 3 fase: gerak dengan percepatan, kecepatan konstan, dan perlambatan.

Abstract

THE DESIGN OF ENVIRONMENTAL RADIOACTIVITY MONITORING SYSTEM SOFTWARE FOR BATAN NUCLEAR INSTALLATIONS AREA. The software for the environmental radioactivity monitoring system for use in the BATAN area has been designed. This software was written in the assembly language for the MCS51. The software is designed to run on the atmospheric radioactivity monitor in the Serpong BATAN nuclear installation area. The hardware is based on the AT89S8253 microcontroller and communicates with a master computer using a wireless modem. The data received by the master computer is to be stored in a database to b processed and displayed in the monitoring system in the form of graphs and data. The database includes date, month, year, and dose rate. The system is controllerd through a provided control panel  RANCANGAN PERANGKAT LUNAK MONITORING RADIOAKTIVITAS LINGKUNGAN KAWASAN INSTALASI NUKLIR BATAN. Telah dirancang perangkat lunak sistem monitoring radioaktivitas lingkungan di kawasan Batan. Perangkat keras yang menggunakan perangkat lunak ini adalah pemantau radioaktivitas udara di kawasan instalasi nuklir BATAN Serpong. Program aplikasi ini bekerja pada perangkat keras berbasis mikrokontroler AT89S8253 yang berkomunikasi dengan suatu komputer master melalui modem nirkabel. Selanjutnya data yang diterima komputer akan disimpan dalam bentuk basis data, dan diolah untuk tampilan dalam sistem monitoring berupa grafik dan data. Basis data yang dihasilkan meliputi tanggal, bulan, tahun dan laju dosis. Pengontrolan sistem ini dilakukan dengan menekan tombol-tombol control panel yang telah disediakan.

Abstract

Family is the first and main place for the growth and development of children. If the condition in the family is good and happy so that the children will grow well. To develop SQ in the family, parents can develop by: duty, care, knowledge, personal change, brotherhood and dedicated leadership. The first place to grow spiritual quotient or spiritual intelligence is family. The children that are grown in high spiritual quotient family environment will be high spiritual quotient people also.

Abstract

Tafsir dakwah is an effort to understand the meaning of Qur?an verses by using dakwah thinking as analysis knife. The good methodology that good to be followed in discussing Tafsir dakwah is thematic method (Maudu?i). By this thematic method, hoped Mufasir will get comprehensive illustration from the Qur?an about dakwah problem that is proposed to him.

Abstract

SOFTWARE DESIGN AND MODELLING OF A MUL T/PURPOSE IRRADIA TOR SYSTEM. Software design and simulation model for a multi-purpose irradiator has been done. The studied irradiator consits of 19 carriers which move along a defined irradiation path where 9 stoppers are also located. These stoppers are used to control the movement of the carriers. Commands are sent from the stoppers in order to move a carrier along the irradiation path or to stop its movement. Mathematical model based on state machine method is applied for simulating the carriers movement along the irradiation path. Based on this mathematical model, an algorithm is made and its corresponding interactive computer program will be developed using the standard graphical interface  DESAIN PERANGKAT LUNAK DAN PEMODELAN SISTEM IRADIATOR SERBAGUNA Dilakukan desain perangkat lunak dan model simulasi sistem iradiator serbaguna. Sistem iradiator yang diteliti memiliki 19 carrier yang berjalan pada lintasan medan iradiasi di mana terdapat 9 stopper. Stopper ini berfungsi untuk mengendalikan gerakan seluruh carrier. Pada stopper terdapat mekamisme untuk memerintahkan carrier bergerak sepanjang segmen lintasan atau tetap diam. Metode state machine dipergunakan dalam pembuatan model matematis untuk menirukan mekanisme gerakan carrier pada lintasannya. Berdasarkan model ini maka akan dibangun algoritma dan kemudian perangkat lunak interaktif yang menggunakan antarmuka grafis
