Hingga saat ini radioisotop tehnesium-99m (99mTc) masih banyak digunakan di bidang kedokteran nuklir di seluruh dunia. Hal ini karena 99mTc memiliki waktu paro 6 jam dan memancarkan gamma murni pada energi 140 keV sehingga merupakan radioisotop yang ideal untuk diagnosis. 99mTc dapat dihasilkan salah satunya dari generator 99Mo/99mTc. Prototipe generator 99Mo/99mTc dibuat dengan menggunakan Molibdenum-98 (98Mo) alam hasil iradiasi neutron, yang dilengkapi dengan kolom berisi material berbasis zirkonium (MBZ) dan kolom alumina. Penentuan performa prototipe generator dilakukan dengan menentukan yield 99mTc, kualitas larutan natrium pertehnetat (Na99mTcO4) yang dihasilkan, dan laju dosis pada permukaan prototipe generator. Yield 99mTc dari prototipe generator yaitu 76,95 ± 7,7%. Prototipe generator menghasilkan radioisotop 99mTc (Na99mTcO4) dengan karakterisitik yang memenuhi persyaratan US Pharmacopoeia, yaitu larutan jernih, memiliki pH 6 ± 0,6, kemurnian radionuklida (lolosan 99Mo) sebesar 0,022 μCi/mCi 99mTc, kemurnian radiokimia 99mTcO4- sebesar 99,85 ± 0,05%, kemurnian kimia (lolosan alumina) < 5 μg/mL, dan laju dosis permukaan prototipe sebesar 1,18 mSv/jam. Dengan demikian prototipe generator 99Mo/99mTc ini sudah menunjukkan performa yang baik dalam menghasilkan radioisotop 99mTc untuk keperluan medis dan memiliki laju dosis yang aman, namun perlu ditingkatkan kembali yieldnya.

Technetium-99m (99mTc), a daughter radionuclide of molybdenum-99 (99Mo), is the most widely used radiodiagnostic agent due to its ideal characteristics. The separation of this radionuclide from 99Mo is commonly performed using alumina. However, a new production method of this radionuclide, which employs a low specific activity 99Mo, makes alumina no longer suitable as separation material. This study aims to develop novel alumina using a facile solid-state reaction for 99Mo/99mTc generator system. The SS-alumina was synthesized from aluminium nitrate nonahydrate and ammonium bicarbonate without solvent. The resulted SS-alumina was then analyzed by FTIR and BET method. 99Mo adsorption and 99mTc releasing study on a series of pH were also performed. FTIR study revealed that the resulting material was Al2O3 with a surface area of 237.65 m2/g. The adsorption capacity, 99mTc yield, 99Mo breakthrough, and alumina breakthrough were 76.06 mg Mo/g alumina, 80.31%, 56.5 µCi/mCi 99mTc, and less than 5 mg/mL, respectively. The elution profile shows a high activity of 99mTc in 2nd and 3rd fraction. It is concluded that the SS-alumina shows good performance as adsorbent material for separation of a 99Mo/99mTc and further work is now underway.

REPRESENTASI PESANTREN DAN KESALAHAN BERBAHASA DALAM NOVEL “CIUMAN TERAKHIR AYAH” KARYA: MAUFIQURRAHMAN SURAHMAN Kadarisman Kadarisman

Publisher : Elementary School Teacher Education (PGSD), STKIP PGRI Sumenep

The novel is one type of prose literary work in which there are building elements such as plot, character, setting, and of course language. As part of literature, novels also have their own genre. Indonesian literature continues to evolve in accordance with the demands and development of the times, and in accordance with the situation and conditions in the community of writers and readers. In the novel Ciuman Terakhir, the work of Maufiqurrahman Surahman will be found in a portrait of the world of pesantren which is very thick. This indicates that the sociology of the author is very influential in constructing a literary work. This can be seen in the way the author chooses diction, plot, builds character, and creates a certain atmosphere in the novel. On the other hand, there are still some language errors in the novel The Last Kiss of the Father. Therefore understanding of linguistic rules is very important, because literary works use language as a medium of liaison between authors and readers.
