“…Menurut Dion et al (2020), fission yield isotop 90 Sr dalam produk hasil fisi bahan bakar 235 U, yaitu sekitar 5,8%[2], sehingga kandungan 90 Sr dalam bahan bakar bekas cukup banyak. Hal ini menyebabkan Isotop 90 Sr sangat ekonomis untuk dipisahkan dan dapat dimanfaatkan untuk keperluan lain, seperti bahan pembuatan baterai [3]. Pemisahan isotop 90 Sr dapat mengurangi limbah radioaktif radiasi tinggi (LiRaRT) yang tersimpan di ruang penyimpanan sementara limbah radioaktif (R.013) sebelum dikirim ke Instalasi Pengelolaan Limbah Radioaktif (IPLR).…”

Bahan bakar nuklir setelah digunakan di reaktor menghasilkan beberapa hasil fisi, dimana salah satunya adalah strontium (90Sr). Isotop strontium dapat dimanfaatkan menjadi bahan baku pembuatan baterai, tetapi strontium tersebut masih tercampur dengan hasil fisi atau isotop lainnya sehingga diperlukan proses pemisahan. Salah satu metode pemisahan strontium adalah dengan adsorpsi. Dalam penelitian ini, campuran TiO2-zeolit Lampung dievaluasi kinerjanya sebagai adsorben sehingga dapat digunakan untuk adsorpsi strontium. Zeolit Lampung awal diaktivasi menggunakan asam sulfat pekat untuk membersihkan pori-pori yang masih mengandung pengotor. Kemudian zeolit dicampurkan dengan TiO2 menggunakan metode stir casting. Adsorben TiO2-zeolit Lampung yang diperoleh kemudian dikarakterisasi menggunakan Fourier Transform Infrared (FTIR), X-Ray Diffraction Spectrometer (XRD), dan Scanning Electron Microscope (SEM). Setelah itu dilakukan uji adsorpsi dengan model isoterm, termodinamika, dan kinetika. Terbentuknya TiO2-zeolit yang dicirikan menggunakan spektroskopi FTIR ditunjukkan dengan adanya puncak serapan Ti-O-Si pada zeolit Lampung setelah ditambahkan TiO2. Hasil analisis menggunakan XRD memperlihatkan zeolit Lampung berjenis klinoptilolit dan mordenit, serta TiO2 yang digunakan memiliki fase anatase. Hasil analisis menggunakan SEM mengindikasikan TiO2 tersebar pada permukaan zeolit Lampung. Model isoterm adsorpsi untuk adsorben TiO2-zeolit memenuhi model isoterm Langmuir. Kajian termodinamika menunjukkan proses adsorpsi bersifat endoterm dan tidak spontan, dan kinetika adsorpsi strontium mengikuti orde kedua semu.Kata kunci: Isoterm, adsorpsi, strontium, TiO2, zeolit.

“…However, the lifetime of MEMS is severely limited by the duration of their internal power sources. Only nuclear microbatteries offer some hope of long independent MEMS powering, which are reviewed in the papers of Blanchard 3 and Jahangiri et al., 4 but other issues, even patients’ fear or misunderstanding of this approach must be considered. As an alternative to pre‐charged batteries, Wireless Power Transfer (WPT) systems allow to continuously power or to recharge periodically the internal MEMS battery using an external WPT system.…”

Electromagnetic Interference and Compatibility (EMI–EMC) are a serious problem in Microelectromechanical Systems (MEMS), and specially in powered by wireless energy transfer MEMS. Most MEMS have dimensions in the order of 1 mm or less, thus, most of the suitable electromagnetic radiation sources have wavelengths larger than this, making isolation of electromagnetic effects very difficult. Model‐Based Systems Engineering (MBSE) can be an excellent tool to deal with EMI—EMC in MEMS during early design phases. In this work, we present a problem‐solving procedure and integration of EMI—EMC in MEMS from a Model‐Based Systems Engineering perspective. This approach is described in detail by a real example using a procedure based on nine steps fully integrated with the proposed systems engineering methodology. For example, the use of context diagrams (IBDs) and N SQUARE charts to describe EMC interactions is explained in detail. The system is formed by a Wireless Power Transfer (WPT) subsystem working near 2.45 or 4.5 GHz coupled to an electromagnetic micromotor. This micromotor contains copper microcoils which can receive electromagnetic radiation directly at the same time that the WPT subsystem. The greatest difficulty is, then, to power the WPT while isolating the micromotor, and optimizing the coupling interface. A summary of the most important EMC concepts and tools are reviewed from the systems engineer perspective and possible problems during the design and testing phases are discussed in detail using the example.
