Modified Fault Tree Method for Vulnerability Analysis of Nuclear Medicine Facility Security System Case study: Radiotherapy Facility, Sardjito General Hospital

Assessing the vulnerability of physical protection systems (PPS) in nuclear medicine facilities is needed to prevent a security incident that could lead to the malicious use of nuclear material. Theft and sabotage of nuclear materials is becoming globally recognized. The current methods of assessing vulnerability tend to be oriented toward complex nuclear security; consequently, it is excessive to use such methods in simple facilities (i.e., radiotherapy facilities in hospitals). The fault tree analysis is a method to assess vulnerability for a simple nuclear facility. The method’s primary events (i.e., basic events and undeveloped events) are able to accommodate fault causes that result from threats. The implementation of this new evaluation method for a radiotherapy facility using Cobalt-60 (Co-60) in Sardjito Hospital shows that its PPS are vulnerable; the threat of interrupting the electrical supply lines make the detection functions fail

OPTIMALISASI INSTALASI PENGOLAHAN AIR LIMBAH (IPAL) MENGGUNAKAN GPS-X

IPAL Cimanggis berlokasi di Jakarta Timur yang bertujuan untuk meningkatkan layanan sanitasi masyarakat dan mengurangi pencemaran lingkungan yang disebabkan oleh air limbah perkotaan yang dibuang secara langsung ke badan air atau ke tanah. Tujuan utama dalam penelitian ini yaitu untuk mengevaluasi efisiensi pengolahan IPAL Cimanggis, selanjutnya dilakukan optimalisasi berdasarkan tiga model yang berbeda untuk meningkatkan efisiensi kinerja IPAL. Analisis laboratorium dan data historis digunakan sebagai data utama untuk memeriksa perilaku instalasi pengolahan. Hasil yang diperoleh dari penelitian ini yaitu bahwa instalasi sudah bekerja dengan baik dalam pengurangan senyawa BOD5, Ammonia, TKN, TN dan Total Alkalinitas. Sedangkan dalam penguraian senyawa TSS, COD dan TP sangat buruk dikarenakan hasil output masih melebihi batas standar baku mutu yang ditetapkan. Software GPS-X digunakan sebagai alat untuk mengoptimalisasi IPAL. Hasil yang diperoleh setelah optimalisasi dilakukan dengan tiga model skenario yaitu, skenario pertama dengan penambahan unit saringan pada awal pengolahan dapat mengurai senyawa TSS sebesar 83,27%, BOD5 6,27%, COD 40,33%, TN 8,90% dan 5,58%. skenario kedua dengann penambahan unit tangki anoxic bahwa persentase penguraian senyawa TSS sebesar 82,37%, BOD5 61,38%, COD 57,14%, Ammonia 0,19%, TKN 24,39%, TN 16,37% dan TP 23,34%. Skenario ketiga dengan menambahkan unit MBR menghasilkan output yang signifikan dalam mengurangi senyawa TSS sebesar 98,18%, BOD5 85,02%, COD 71,37%, Ammonia 82,45%, TKN 68,28%, TN 76,97% dan TP 42,32%

Neutronic Analysis of the RSG-GAS Fuel Using Burnable Poison

Control and safety of nuclear reactors are significantly influenced by the determination of safety parameters. The three most crucial safety factors for assessing reactor status are the infinite multiplication factor, reactivity coefficients, and power peaking factor. The objective of the present study is to examine how the RSG-GAS fuel safety parameters behave in a typical reactor operation state. A lattice cell fuel model of the fuel lattice of the RSG-GAS reactor core was modeled using WIMSD-5Bwith cross-section library data based on ENDF/B-VIII.0. The value of the infinite multiplication factor with various burnable poison concentrations, as well as the moderator and fuel temperatures, were the variables that were examined. The reactivity coefficient parameters were similarly analyzed. By comparing the WIMSD-5B code results with information from the SAR document, the WIMS model for RSG-GAS fuel was verified, and it was inferred that the parameters are in good agreement. Safe behavior uses the predicted reactivity coefficient values as an example

Developing Nuclear Security Capacity of Indonesia’s Police and Security Officer: Lessons from Universitas Gadjah Mada’s Pilot Training

Due to an increase in global nuclear security issues, there need to be improvements in human resources and security measures. The Republic of Indonesia is an archipelago country, which makes surveilling for nuclear security threats complicated. Recent radioactive material smuggling incidents proved that Indonesian police and security officers’ knowledge in nuclear security has been challenged and must be improved. In response, Universitas Gadjah Mada’s Nuclear Engineering Program composed a three-day pilot training program for local police and UGM\u27s security officers in 2018. The objective of the training was to improve their capabilities in dealing with nuclear security issues around where they work and serve. Training materials were designed to introduce nuclear technology and provide the basic skills of handling nuclear security matters. The training was divided into 12 sessions, based on the needs stated by the Special Region of Yogyakarta\u27s police chief. Lessons were delivered through traditional teaching, table-top exercises, exercises, and discussion. Fifteen-question pre-tests and post-tests were conducted to assess the officers’ knowledge of the training materials and the benefits of being trained. Based on the tests, we concluded that the participants’ understanding of nuclear security had improved. This increase in understanding was because the training materials fit their job needs, presented in various methods, and the participants’ awareness grew. It led to an increase in their awareness for securing the facilities utilizing radioactive sources in the Yogyakarta area. They said that the number of trainees in this event still does not meet the number of facilities that have to be secured. Therefore, the training should be carried out again and can be improved based on the participants\u27 feedback. Furthermore, this training could be expanded and applied to the whole country

Proceedings of the 3rd International Conference on Community Engagement and Education for Sustainable Development

This proceeding contains articles on the various ideas of the academic community presented at The 3rd International Conference on Community Engagement and Education for Sustainable Development (ICCEESD 2022) organized by the Universitas Gadjah Mada, Indonesia on 7th-8th December 2022.  ICCEESD is a biannual forum for sharing, benchmarking, and discussing HEI’s activities in developing Education for Sustainable Development towards community engagement. Education for Sustainability as a teaching strategy for resolving community challenges through formal, informal, or non-formal education is expected to benefit from various community service best practices by academics, researchers, and students. The 3rd ICCEESD has “Strengthening Education for Sustainability Towards Better Community Engagement” as its theme this year. It is expected that the 3rd ICCEESD will provide a forum for the presenters and participants to exchange best practices, policies, and conceptual implementation of Education for Sustainability towards better community engagement and explore ideas to address community needs.  Conference Title: 3rd International Conference on Community Engagement and Education for Sustainable DevelopmentConference Theme: Strengthening Education for Sustainability Towards Better Community EngagementConference Acronyms: ICCEESD 2022Conference Date: 7th-8th December 2022Conference Location: Grand Rohan Jogja Yogyakarta, IndonesiaConference Organizer: Universitas Gadjah Mada, Indonesi
