Abstract

Radionuklida merupakan unsur cemaran yang sangat penting untuk diketahui persebarannya. Radionuklida137Cs bersifat konservatif sehingga penyebarannya dalam laut sangat dipengaruhi oleh proses pencampuran dan difusi. Tujuan dari penelitian ini memodelkan distribusi radionuklida137Cs di Perairan Teluk Jakarta seandainya di Muara Sungai Cisadane terdapat limbah 137Cs dengan pendekatan model hidrodinamika menggunakan Software Surface Water Modelling System (SMS). Penelitian ini dibagi dalam dua tahap yaitu tahap survey lapangan dan tahap pemodelan hidrodinamika menggunakan Software Surface Water Modeling System (SMS) modul Resources Management Associates-2 (RMA2) untuk memodelkan arah dan kecepatan arus laut serta dilanjutkan modul Resources Management Associates-4 (RMA4) untuk memodelkan distribusi 137Cs. Metode penelitian ini menggunakan metode kuantitatif dan penetapan lokasi penelitian dipilih secara purposive sampling. Hasil penelitian menunjukan bahwa kondisi hidrodinamika perairan Teluk Jakarta menunjukkan bahwa kecepatan arus maksimum yaitu 0,036 m/s pada saat pasang. Distribusi Radionuklida 137Cs di perairan Teluk Jakarta selama 15 hari menunjukkan, bahwa 137Cs telah menyebar lebih dominan ke arah timur, namun nilai aktivitasnya masih lebih banyak terdapat didaerah awal mulanya lepasan. Hal ini menunjukan ternyata waktu simulasi selama 15 hari nilai aktivitas 137Cs belum mampu tersebar seluruhnya ke perairan laut, karena lemahnya arus.

Abstract

This research examines the representation of the age gap in the film ‘Sweet 20’ using a qualitative descriptive approach. The film focuses on the theme of ageism seen in the interaction between the older and younger generations ranging from family environment, peers, public places, to the desire to be young again. This research found that the film ‘Sweet 20’ displays significant ageism, especially in how the older generation is considered unproductive and does not have a significant role in the family. The results of this study show that the film ‘Sweet 20’ represents ageism as a common culture in society, where the older generation is considered to have no value and no significant role in family life. This study also found that the film ‘Sweet 20’ not only presents ageism as a culture, but also as part of a social structure that affects the behaviour of individuals in society. Thus, this research shows that the film ‘Sweet 20’ has significant power in understanding and critiquing ageism as a common culture in society.
