Abstract

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.

Abstract

Environmental education aims to create people who have good environmental literacy. This study tries to explain previous studies related to how the level of students’ literacy and stakeholders’ literacy in green open space affects students' environmental literacy. This is descriptive research conducted in SMPN 2 Suayan. The purposes of this study are 1) to identify the environmental literacy of the students and the school community in the green open space 2) to identify the difference between students’ environmental literacy and school community in green open space. The sample consists of 70 students and 40 people from the school community. Measurement of environmental literacy is discussed in 3 domains, namely the domain of knowledge, attitudes towards the environment, and behavior towards the environment. The total number of instruments is 45 items. The reliability value of instruments for knowledge, attitude, and behavior domains are 0.874, 0.927, and 0.965, respectively, and are the high category. Collected data of students and school community were analyzed by using Microsoft Excel and SPSS. The difference in environmental literacy of students and school community in green open space was analyzed by using Mann-Whitney U Test. The environmental literacy value of students and school community are respectively 77.1% and 79.7% and are high category. The analysis on the achievement of environmental literacy scores shows that there are no significant differences in both groups. This concludes that the school community that has good environmental literacy will give a good influence on students’ environmental literacy and knowledge. The last, by knowing the roles of the school community and availability of green open space on achieving environmental literacy of students, all related stakeholders are suggested to upgrade the environmental literacy of the school community and support the availability of green open space in the school area.
