Abstract

Uranium waste generated from the utilization of nuclear technology on radioisotope production, nuclear fuel production, calibration of fuel post-irradiation, and the purification of uranium from yellow cake. Uranium is a long-lived radionuclides and hazardous if it was entered in human body, thus requiring appropriate treatment with high safety. The processing conducted by separated the uranium which was contained on waste with ions exchange process. Uranium has been separated, later then immobilized with the polymer. The study of simulation uranium waste processing using an Alumina Silica Phosphate (ASP) has been conducted. Simulation uranium waste with the concentration of 0,05 g/l was contacted to ASP with contact timer and pH as a parameters. The Alumina Silica Phosphate which saturated with uranium, later then immobilized with epoxy resin polymer by total of waste contents as a parameter. The immobilization was conducted by mixing ASP which saturated with uranium and epoxy resin. The study showed that the best composition of ASP was obtained at the ratio of 1:1, contact time of 15 minute, and pH of 7 with absorption of uranium about 93,5%. The characteristic of polymer and the immobilization waste showed that optimum of waste content is 20% of weight with the density of 1,0538 g/cm3; compressive strength of 19,96 kN/cm2 and there was not detected the leaching of uranium which out from the polymer-waste. Therefore, ASP can be used on processing of uranium waste and could be suggested to be applied on Radioactive Waste Management Installation.

Abstract

Menurut Undang-Undang No 14 tahun 2005 tentang guru dan dosen kompetensi profesional merupakan salah satu kompetensi inti yang harus dimiliki guru. Prodi PGMI membekali kompetensi profesional para mahasiswa melalui beberapa mata kuliah bidang keahlian agar mereka dapat menjadi guru kelas yang profesional antara lain: IPA, Matematika, Bahasa Indonesia, PPKN, dan IPS. Agar memiliki penguasaan konsep IPA dengan baik prodi menyiapkan beberapa matakuliah IPA antara lain IPA MI-I dan IPA MI-II, pembelajaran IPA MI. Dengan beberapa mata kuliah ini diharapkan mahasiswa sudah memiliki kemampuan dalam melakukan proses pembelajaran IPA, Bahasa Indonesia dan matematika dengan menguasai ketiga konsep IPA dengan luas dan mendalam. Berdasarkan penelitian pendahuluan diperoleh data bahwa penguasaan konsep IPA mahasiswa PGMI masih berada pada kategori rendah. Selain itu, merekan juga mengalami beberapa kesulitan dalam mempelajari konsep-konsep tersebut. Berdasarkan Latar Belakang masalah tersebut maka permasalahan yang ingin dijawab dalam penelitian ini adalah Bagaimanakah kemampuan tingkat penguasaan konsep IPA mahasiswa PGMI dan Kesulitan-kesulitan apakah yang dihadapi mahasiswa PGMI dalam menguasai konsep IPA. Meode yang dgunakan merupkakan metode deskriptif dengan instrumen tes untuk mengetahuai penguasaan konsep IPA dan wawancara untuk emnemukan kesulitan mahasiswa dalam mempelajarai materi. Hasil peneltian menunjukkan bahwa penguasaan konsep IPA mahasiswa PGMI masih sangat bervariasi. Akan tetapi hampir semua mahasiswa yang menjadi subyek penelitian memiliki kemampuan penguasaan konsep yang berada pada kategori baik dan cukup tidak ada satu mahasiswapun yang memiliki kemampuan penguasaan konsep yang berada pada kaegori sangat baik. Sedangkan kesulitan mahasiswa mempelajari IPA karena konsep IPA SD/MI sangat banyak dan tidak semua materi IPA SD/MI masuk dalam materi ajar perkuliahan IPA. Selain itu mahasiswa juga mengalami kesulitan mempelajari IPA karena ada sebagian materi iPA yang disajikan tidak diiringi dengan kegiatan praktek atau pengamatan langsung.

Abstract

Dalam produksi radioisotop 99Mo akan ditimbulkan limbah radioaktif yang mengandung campuran uranium dan hasil belah. Pengolahan dilakukan untuk memisahkan uranium dari hasil belah menggunakan resin penukar anion. Resin penukar anion akan selektif mengikat uranium dalam bentuk uranium kompleks. Telah dilakukan penelitian pengolahan limbah simulasi dengan konsentrasi uranium 0,05g/L menggunakan resin penukar anion amberlit IRA-400(Cl) dengan cara mengkomplekkan uranium dengan Na2CO3. Variable yang dipelajari adalah jumlah Na2CO3 dan waktu kontak. Penjerapan uranium yang optimal diperoleh pada penambahan Na2CO3. 0,75 gram (U / Na2CO3 ? 0,067), waktu kontak 60 menit dengan penjerapan uranium 88,6 % berat. Resin IRA-400 (Cl) yang jenuh uranium disolidifikasi dengan polimer resin epoksi. Karakterisasi polimer-limbah hasil solidifikasi dilakukan dengan pengukuran densitas, kuat tekan dan laju pelindihan. Densitas ditentukan dengan mengukur berat dan volume polimer-limbah, kuat tekan ditentukan dengan alat uji tekan Paul Weber dan laju pelindihan ditentukan dengan alat sokhlet. Hasil pengukuran menunjukkan bahwa kandungan limbah yang optimal adalah 20 % berat dengan densitas 1,036 g/cm3, kuat tekan 12,153 kN/ cm2dan tidak terdeteksi adanya pelindihan uranium keluar dari polimer-limbah.

STUDI PENGELOLAAN BAHAN BAKAR NUKLIR BEKAS PLTN JENIS PWR DAN BWR. Telah dilakukan studi tentang pengelolaan bahan bakar nuklir bekas sebagai upaya antisipasi bagi program pengoperasian PLTN di Indonesia. Dalam makalah ini diperkirakan kuantitas bahan bakar nuklir bekas (B2NB) yang ditimbulkan berdasarkan skenario pemenuhan kebutuhan energi listrik nasional, tingkat daya dan tipe PLTN kemudian dibahas alternatif pengelolaanya terkait dengan strategi daur bahan bakar nuklir yang akan dikembangkan. Data untuk perkiraan digunakan PLTN jenis Pressure Water Reactor (PWR) untuk tingkat daya 1.000 MWe. Dengan melakukan komparasi pengalaman negara-negara yang sudah mengoperasikan PLTN, ada empat strategi daur bahan bakar nuklir yang dapat dilakukan yaitu : direct disposal, reprocessing, DUPIC (Direct Use of Spent PWR Fuel In Candu) dan wait and see. Terkait dengan B2NB yang ditimbulkan ada empat alternatif pengelolaanya yaitu : penyimpanan sementara di lokasi reaktor (at the reactor/AR), disediakan fasilitas tersentralisasi jauh dari reaktor (away from reactor/AFR) tipe basah, disediakan AFR tipe kering atau mempersiapkan fasilitas reprocessing. Untuk kasus di Indonesia, metode pengelolaan B2NB secara AFR tipe basah adalah pilihan yang paling tepat jika yang akan dioperasikan adalah PLTN jenis PWR atau BWR. Kata kunci : pembangkit listrik tenaga nuklir, bahan bakar nuklir bekas THE STUDY OF MANAGEMENT SPENT FUEL FROM NPP’S PWR AND BWR TYPE. Management of spent nuclear fuel from Nuclear Power Plant (NPP) reactor had been studied to anticipate for program of NPP operation in Indonesia. In this paper the quantity of spent nuclear fuel (SNF) predicted. Data for the estimate used NPP type Pressure Water Reactor (PWR) 1.000 MWe and the SNF management overview base on the experiences of some countries that have NPP. There are four strategy nuclear fuel cycle which can be developed i.e : direct disposal, reprocessing, DUPIC (Direct Use of Spent PWR Fuel In Candu) and wait and see. And four alternative for SNF management that are : store in the reactor building (AR), make wet centralized storage AFR, make dry centralized storage AFR and prepare for reprocessing facility.
