PEMETAAN DISTRIBUSI KANDUNGAN RADIOISOTOP DI DAERAH PERKEBUNAN UBI KAYU DI NUABOSI ENDE FLORES

Abstract

ABSTRAK Telah dilakukan penelitian di wilayah perkebunan ubi kayu Desa Ndetundora III Nuabosi Kecamatan Ende Kabupaten Ende mengenai pemetaan distribusi kandungan radioisotop. Tujuan penelitian ini menentukan interval cacah radiasi dan temperatur di daerah perkebunan, memetakan distribusi kandungan radiosotop di daerah perkebunan berdasarkan cacah radiasi dan temperatur serta mengestimasi luas daerah yang cacah radioisotopnya cukup tinggi. Metode penelitian yang digunakan terdiri dari observasi, mapping, analisis dan interpretasi data. Data yang diperoleh dalam penelitian di lapangan adalah nilai cacah radiasi permenit (Cpm), temperatur tanah, elevasi dan data lintang bujur, data-data ini yang kemudian digunakan untuk membuat peta. Hasil penelitian diperoleh bahwa distribusi kandungan radioisotop di lokasi berkisar dari 11 cpm - 22 cpm dan temperatur berkisar dari 22oC - 31oC. Keseluruhan area penelitian memiliki kadar radiasi yang rendah. Kontaminasi radioisotop pada lingkungan masih tergolong rendah dan secara umum cacah radiasi dan temperatur masih berada pada batas toleransi. ABSTRACT [Title: Distribution Mapping Of Radioisotop Content In Wooden Sweet Plant Areas In Nuabosi Ende Flores] Research has been carried out in the cassava plantation area of ​​Ndetundora III Nuabosi Village, Ende Sub-district, Ende Regency about the distribution mapping of radioisotope content. The purposes of this study are; first, to determine the interval of radiation counts and temperatures in the plantation area: Second, to map the distribution of radioisotope content in the plantation area based on radiation counts and temperature; Third, to estimate the area with a high radioisotope count. The research method that used in this study consists of observation, mapping, analysis and interpretation of data. Data obtained in the field of research are the value of radiation counts per minute (Cpm), soil temperature, elevation and latitude longitude data, these data are then used to make maps. The results showed that the distribution of radioisotope content in the research sites based on radiation counts, ranged from 11 cpm - 22 cpm and temperatures ranged from 22oC - 31oC. The entire research area has low radiation levels. Radioisotope contamination in the environment is still classified as low contamination and generally the radiation count and temperature are still at the tolerance limit.
