Abstract

DEVELOPMENT OF SOFTWARE PACKAGE OF NUCLEAR REACTOR SIMULATOR FOR NPP SOCIALIZATION. Development of software package of nuclear reactor simulator for socialization of nuclear power plant has been carried out. This work used RSG GA Siwabessy as a model reactor. The choice of RSG GAS to be simulated is based on consideration of its complete physical characteristic and operation data. To simulate processes occurring in the reactor, the simulator program simulates them as many as possible through a compact display. This simulator is developed using a programming software package LabVIEW to describe process computation in the reactor. Dynamic displays demonstrating any dynamic processes occuring in RSG GAS have been simulated. The result of this development is a software package that is able to simulate RSG GAS operational system. The development of this simulator including its neutronik and thermohidraulic aspects is outlined in this paper.  RANCANG BANGUN PERANGKAT LUNAK SIMULATOR REAKTOR NUKLIR UNTUK SOSIALISASI PLTN. Telah dilakukan rancang bangun perangkat lunak simulator reaktor nuklir untuk sosialisasi PLTN. Pada kegiatan ini, RSG GA Siwabessy digunakan sebagai suatu model. Pemilihan RSG GAS untuk disimulasikan berdasarkan pertimbangan kelengkapan data karakteristik fisis dan data operasi. Rancang bangun perangkat lunak ini dilakukan dalam bentuk visualisasi proses operasi yang ada di dalam RSG GA Sywabessy dan dibuat dengan menggunakan perangkat lunak Labview. Untuk menyimulasikan proses yang terjadi di dalam reaktor, simulator menampilkan sebanyak mungkin proses yang terjadi melalui tampilan yang kompak. Perangkat lunak simulator ini dirancang-bangun dengan memanfaatkan paket program LabVIEW untuk menyimulasikan perhitungan proses yang ada di dalam teras reaktor.

Abstract

Background. Congenital heart disease (CHD) is a significant cause of mortality in pediatric patients. Meanwhile, malnutrition remains a public health problem in Indonesia. Combined with infection, these condition will increase mortality rate of patients with CHD.Objectives. The objective of this study is to describe the cause of mortality among CHD patients who were hospitalized in pediatric ward, Doctor Soetomo General Hospital, Surabaya during period 2004-2006.Methods. This study is a descriptive evaluation base on Medical Record data.Results. Of patients hospitalized from 2004 to 2006, 189, 185, and 186 respectively grouped into neonatal, infant, and childhood age. Medical record data in 3 years was described into distributive frequency and cross table. Ventricular septal Defect (VSD), Tetralogy of Fallot (TOF), Atrial Septal Defect (ASD), and Patent Ductus Arteriosus (PDA) were the four major CHD. Hospital mortality rate was 11,64% (2004), 11,35% (2005), and 13,44% (2006), infant were the main portion 72,73% (2004), 76,19% (2005), 64% (2006). Respiratory and cardiac failure were two leading cause of death. Fifty percent of death case was underlied by pnemonia and bronchiolitis. VSD, ASD and TOF were the most common CHD associated with mortality. Death rate was significantly high in malnourished patients, from 2004 to 2006: 45,45% (10/22), 66,67% (14/21),  and 72% (18/25) respectively.Conclusions. High mortality rate in our patients with with CHD were associated with age (first year of life), respiratory infections (pnemonia, bronchiolitis), and malnutrition.

Abstract

PEMBUATAN PROTOTIPE SISTEM DETEKSI BATUBARA SECARA ON-LINE PADA BELT CONVEYOR DENGAN TEKNIK AKTIVASI NEUTRON. Pemanfaatan teknik aktivasi neutron secara on-line pada batubara diajukan sebagai alternatif atas teknik cuplikan. Dibandingkan dengan teknik konvensional tersebut, teknik aktivasi neutron secara on-line memiliki waktu analisis yang lebih singkat dan hasil analisis yang lebih akurat. On-line analyzer ini terdiri atas sistem deteksi, sistem akuisisi data, dan computer console. Pembuatan prototipe sistem deteksi on-line analyzer untuk batubara diuraikan dalam makalah ini. Sistem deteksi tersebut meliputi sejumlah modul, yaitu detektor NaI(Tl) yang dilengkapi dengan photomultiplier tube (PMT), pre-amplifier, single channel analyzer (SCA), dan processor penghitung pulsa dan transmitter sinyal analog. Proses pembuatan keempat modul ini melibatkan penentuan blok konfigurasi, pembuatan lay out, dan pemilihan komponen elektronik. Modul tersebut telah berhasil diintegrasikan dan diuji. Sistem deteksi ini diuji dengan menggunakan sampel unsur radioaktif Zn-65, energi 1115,5 Kev dan  aktifitas 1 µCi. Hasil pengujian menunjukkan bahwa prototipe sistem deteksi on-line analyzer telah berfungsi sesuai dengan rancangan.Kata kunci: Sistem deteksi, on-line analyzer, batubara, aktivasi neutron CONSTRUCTION OF PROTOTYPE OF ON-LINE ANALYZER DETECTION SYSTEM FOR COAL ON BELT CONVEYOR USING NEUTRON ACTIVATION TECHNIQUE. The use of on-line neutron activation technique for coal analysis is proposed as an alternative method for analysis based on sampling technique. Compared to this conventional technique, the on-line neutron activation technique has much shorter time of analysis and more accurate results. The construction of detection system prototype for the on-line analyzer is described in this paper. This on-line analyzer consists of detection system, data acquisition system, and computer console. This detection system comprises several modules, i.e. NaI(Tl) scintillation detector completed with a photomultiplier tube (PMT), pre-amplifier, single channel analyzer (SCA), and analog signal transmitter and pulse counter processor. The construction processes of these four modules include the development of configuration block, lay out, and selection of electronic components. The modules have been integrated and tested. This detection system was tested using radioactive element Zn-65 having energy of 1115.5 keV and activity of 1 µCi. The test results show that the prototype of the on-line analyzer detection system has functioned as expected.Keywords: Detection system, on-line analyzer, coal, neutron activation

Abstract

The background of this study is the effort of solving the inheritance problem faced by Malaysia in the case of Malay Palace dance which is currently in decline. This study is done by using best practice from the The Development and Inheritance of Yogyakarta Classical Dance (TKGY) done by the Ngayogyakarta Hadiningrat Palace and some formal and non-formal institutions in Yogyakarta, Indonesia. TKGY is chosen as it is viewed to have positive life in classical Palace dance and involve various actors and clear strategies. For three years, the researcher has done the research by observing the inheritance context (TKGY) to identify preservation phenomena done in Yogyakarta. This research is using a qualitative approach. The data are collected by doing in-depth interviews with some leaders of the main studios in Yogyakarta and Malay Palace dance choreographers in Malaysia. The result of the research shows that there are some similarities and differences between Malay palace dance in Malaysia and Yogyakarta classical dance. Some strategies have been used to describe how the Malaysian government adopts inheritance strategies (TKGY) used by actors in the inheritance discourse (TKGY).How to Cite: Saearani, M. F. T.
