An environmental radiation monitoring system that continuously measures gamma dose rate around nuclear facilities is an important tool to present dose rate information to the public or authorities for radiological protection during both normal operation and radiological accidents. We have developed such a system that consists of six GM-based device for monitoring the environmental dose rate around Serpong Nuclear Complex. It has operated since 2010. In this study, a description of the system and analysis of measured data are presented. Analysis of the data for the last five years shows that the average dose rate levels were between 84-99 nSv/h which are still lower than terrestrial gamma radiation levels at several other locations in Indonesia. Time series analysis of the monitoring data demonstrates a good agreement between an increase in environmental gamma dose rate and the presence of iodine and argon in the air by in situ measurement. This result indicates that system is also effective for an early warning system in the case of radiological emergency.

G.A. Siwabessy Multipurpose Reactor (RSG-GAS) is a research reactor with thermal power of 30 MW located in the Serpong Nuclear Area (KNS), South Tangerang, Banten, Indonesia. Nuclear emergency preparedness of RSG-GAS needs to be improved by developing a decision support system for emergency response. This system covers three important aspects: accident source terms estimation, radioactive materials dispersion model into the atmosphere and radiological impact visualization. In this paper, radioactive materials dispersion during design basis accident (DBA) is modeled using HotSpot, by utilizing site-specific meteorological data. Based on the modelling, maximum effective dose and thyroid equivalent dose of 1.030 mSv and 26 mSv for the first 7 days of exposure are reached at distance of 1 km from the release point. These values are below IAEA generic criteria related to risk reduction of stochastic effects. The results of radioactive dispersion modeling and radiation dose calculations are integrated with Google Earth Pro to visualize radiological impact caused by a nuclear accident. Digital maps of demographic and land use data are overlayed on Google Earth Pro for more accurate impact estimation to take optimal emergency responses.Keywords: G.A.

Lulusan suatu lembaga persekolahan baik formal maupun nonformal sangat dipengaruhi oleh Mutu suatu Pendidikan. Dalam peningkatan mutu Pendidikan dibutuhkan adanya strategi yang baik dan harus direncanakan dengan manajemen yang baik pula. Manajemen strategi yang baik akan memberikan keputusan organisani untuk meningkatkan mutu atau keunggulan organisasni tersebut, dan itu diperlukan adanya perencanaan, implementasi dan evaluasi yang terkoneksi dengan baik. Untuk mengetahui apasaja yang menjadi faktor pendukung dan penghambat yang di hadapi Lembaga Penyelenggara Program Pendidikan kesetaraan Paket C di Kecamatan Campurdarat, Kabupaten Tulungagung dalam peningkatan mutu pendidikan Program Paket C; Untuk mengetahui bagaimana upaya menghadapi kendala dalam meningkatkan mutu pendidikan kesetaraan Paket C di Kecamatan Campurdarat, Kabupaten Tulungagung; Untuk menegetahui bagaimana strategi peningkatkan mutu pendidikan kesetaraan Paket C di Kecamatan Campurdarat, Kabupaten Tulungagung. Penelitian ini menggunakan metode deskriptif kualitatif dan tehnik pengumpulan data adalah wawancara, observasi dan dukumentasi. Dari hasil penelitian ditemukan bahwa dalam penentuan strategi peningkatan mutu Pendidikan kesetaraan paket C di kecamatan Campuradat, telah menerapkan Manajemen Strategi yang meliputi aspek fungsi perencanaan, Inplementasi serta evaluasi, secara umum telah sesuai harapan serta berjalan secara terstruktur dan perlu pembenahan dalam implementasinya supaya dapat mencapai tujuan seperti yang diharapkan, yaitu adanya peningkatan mutu Pendidikan Program kesetaraan Paket C setara SMA.

DESIGN, IMPLEMENTATION AND VERIFICATION OF SOFTWARE CODE FOR RADIATION DOSE ASSESSMENT BASED ON SIMPLE GENERIC ENVIRONMENTAL MODEL.Radiation dose assessment to determine the potential of radiological impacts of various installations within nuclear facility complex is necessary to ensure evironmental and public safety. A simple generic model-based method for calculating radiation doses caused by the release of radioactive substances into the environment has been published by the International Atomic Energy Agency (IAEA) as the Safety Report Series . In order to assist the application of the assessment method and a basis for the development of more complex assessment methods, an open-source based software code has been designed and implemented. The software comes with maps and is very easy to be used because assessment scenarios can be done through diagrams. Software verification was performed by comparing its result to SRS-19 and CROM software calculation results. Dose estimated by SRS-19 are higher compared to the result of developed software. However, these are still acceptable since dose estimation in SRS-19 is based on conservative approach. On the other hand, compared to CROM software, the same results for three scenarios and a non-significant difference of 2.25% in another scenario were obtained. These results indicate the correctness of our implementation and implies that the developed software is ready for use in real scenario. In the future, the addition of various features and development of new model need to be done to improve the capability of software that has been developed.Keywords: Radiation dose assessment, software code, radioactive discharge, environment, IAEA SRS-19.
