Telah dibuat perangkat lunak untuk mendukung sistem akuisisi data (Data Acquisition System, DAS) pengukur kanal temperatur dengan menggunakan antarmuka kartu multifungsi 12 Bit. Perangkat lunak tersebut dipasangkan pada komputer personal dengan operasi yang dijalankan melalui program Delphi. Program diatur melalui pemilihan menu yang bervariasi seperti " DAC Type and Parameters", "Amp-Mux Type and Parameters" dan "Graph Mode". Dari hasil uji coba dapat ditunjukan bahwa aplikasi yang dikembangkan dapat digunakan sebagai Sistem Akuisisi Data pengukur kanal temperatur di fasilitas Termohidrolik Reaktor.

Soil contamination may occur in the upcoming decommissioning activities of the TRIGA2000 Reactor. Measurement of contaminant radioactivity, which can be performed using single-channel spectroscopy, is required in soil decontamination processes. This research develops a timer/counter system for single-channel spectroscopy using a microcontroller. The performance of the ATMega328P microcontroller Timer/Counter on Arduino has been tested for single-channel spectroscopy. Microcontroller's Timer/Counter 1 is used as a counter while Timer/Counter 2 is used as a timer. Tests include the linearity test, comparative test, and chi-square test. The test results show that the ATMega328P microcontroller Timer/Counter works well and can be used as the end of a single-channel spectroscopic system.

In this study, as a part of the development of the radiation mapping technology, we are planning to develop the gamma-ray imager based on a passive detector such as a dosimeter. For this purpose, we demonstrated the use of nanoDot OSLD as a passive detector being irradiated inside a soft x-ray machine then combined the irradiation position (qualitatively) with radiation dose (quantitatively) for visualization purpose. The experimental results showed that the NanoDots exhibit good linearity and reproducibility when subjected to soft X-rays machine, Hence, the nanoDots showed a promising potential for visualization of dose distribution.

We developed a gamma ray detector with an LuAG:Pr scintillator and an avalanche photodiode as a detector for a positron emission tomography (PET) system. Studies have been performed on the influences of gamma irradiation on application-specific integrated circuit (ASIC) preamp boards used as a detector module. As a device used in nuclear environments for substantial durations, the ASIC has to have a lifetime long enough to ensure that there will be a negligible failure rate during this period. These front-end systems must meet the requirements for standard positron emission tomography (PET) systems. Therefore, an equivalent noise charge (ENC) experiment is needed to measure the front-end system's characteristics. This study showed that minimum ENC conditions can be achieved if a shorter shaping time could be applied.

Telah dilakukan kajian tentang sistem pengukur daya reaktor pada kanal daya tinggi serta telah dicoba perancangan alat ukur daya reaktor untuk tiga dekade teratas atau dalam rentang 1%-100% pengukuran daya. Sistem pengukur daya reaktor pada kanal daya tinggi dibentuk sebagai pengukur arus luaran detektor nuklir yang ditempatkan dalam tangki reaktor, proporsional terhadap besarnya fluks neutron yang terdeteksi dan seterusnya adalah proporsional dengan daya thermal reaktor. Sistem dibentuk sebagai pengukur arus yang berkisar dari 1 mikroampere-1 miliampere dalam tiga skala ukur yang dikontrol secara otomatis dengan memanfaatkan sistem mikrokontroler. Dari hasil pengujian di laboratorium dengan menggunakan sumber arus yang presisi dapat disimpulkan bahwa sistem pengukur daya reaktor yang dirancang dapat digunakan dan dapat dikembangkan lebih lanjut menjadi pengukur daya reaktor untuk kanal daya menengah.
