Abstract

Kebakaran hutan merupakan salah satu penyebab kerusakan hutan yang berdampak pada penurunan kualitas lingkungan. Untuk mengetahui dampak kualitas udara akibat kebakaran hutan, telah dilakukan karakterisasi dan evaluasi cuplikan partikulat udara yang dikumpulkan pada periode terjadinya kebakaran hutan di Pekanbaru. Karakterisasi cuplikan telah dilakukan dengan metode AAN yang memiliki beberapa kelebihan antara lain sensitivitas tinggi, multiunsur dan limit deteksi yang rendah. Validasi metode dilakukan pengujian terhadap cuplikan bahan acuan SRM NIST 1648a Urban Particulate Matter. Konsentrasi massa saat terjadi kebakaran hutan di Pekanbaru terdeteksi 5 hingga 7 kali lebih tinggi dari kondisi normal. Hasil karakterisasi cuplikan telah terkuantifikasi 15 unsur (Al, Ca, Ti, Cl, Mn, As, Br, Na, K, As, Fe, Zn, Cr, Co, Sb). Output dari kegiatan ini diharapkan dapat menggambarkan unsur utama yang menjadi indikator sumber pencemar yang selanjutnya dapat digunakan sebagai early warning dalam mengantisipasi bencana kebakaran hutan. Selain itu evaluasi unsur karsinogenik dan non-karsinogenik dapat menunjukkan resiko kesehatan masyarakat di sekitar lokasi kebakaran hutan yang secara tidak langsung dapat terpapar oleh emisi sumber partikulat udara.

Abstract

Rare earth elements (REE) are present in the lanthanide range and are widely used in high-tech and clean technology applications that are predicted to grow significantly in the coming decades. Therefore, there will be a high demand for REE in the future that will impact the needs for development of sensitive and selective methods for determination of REEs such as X-Ray Fluorescence (XRF). Reliability of REEs analysis results depend on analytical capability of XRF instrument’s performance. Analytical capability shows the ability of the instrument to perform sample analysis with high accuracy and precision and proven by validation so that the results obtained are reliable. The aim of this study is to assess the analytical capability of XRF for REEs analysis in samples particularly Lanthanum (La), Cerium (Ce), Neodymium (Nd), Samarium (Sm) and Yttrium (Y), by performing method validation of energy dispersive x-ray spectrometers (ED-XRF). Four measurement conditions that covered the selected elements were defined. Accuracy, precision and detection limits determination were performed by measuring the CRM In House Monazite Sand. The yield of the selected element corresponds to its certified value, with a %recovery between 95.99 to 103.1%. The %RSD values ranging from 0.59 to 5.19%. The detection limits (LLD) of ED-XRF ranged from 8.78 to 67.4 ppm. The results showed the good analytical capability of ED-XRF method for REEs analysis.

Abstract

Inter-comparison program is a good tool for improving quality and to enhance the accuracy and precision of theanalytical techniques. By participating in this program, laboratories could demonstrate their capability andensuring the quality of analysis results generated by analytical laboratories. The Neutron Activation Analysis(NAA) laboratory at National Nuclear Energy Agency of Indonesia (BATAN), Nuclear Technology Center forMaterials and Radiometry-PTNBR laboratory participated in inter-comparison tests organized by NAA workinggroup. Inter-comparison BATAN 2009 was the third inter-laboratory analysis test within that project. Theparticipating laboratories were asked to analyze for trace elements using neutron activation analysis as theprimary technique. Three materials were distributed to the participants representing foodstuff, and environmentalmaterial samples. Samples were irradiated in rabbit facility of G.A. Siwabessy reactor with neutron flux ~ 1013n.cm-2.s-1, and counted with HPGe detector of gamma spectrometry. Several trace elements in these sampleswere detected. The accuracy and precision evaluation based on International Atomic Energy Agency (IAEA)criteria was applied. In this paper the PTNBR NAA laboratory results is evaluated.Keywords: inter-comparison, neutron activation analysis, trace elements, foodstuff, environmental samples,NAA laboratory
