Indonesia’s Shifting Focus of Energy Security Amidst COVID-19

AbstrakBerbagai dimensi dari konsep ketahanan energi menjadikannya topik diskusi besar di saat pandemi. Pergeseran dinamis dari ketahanan energi dapat dilihat baik dalam skala internasional maupun domestik. Makalah ini akan berfokus pada perubahan dinamis ketahanan energi di Indonesia dengan menganalisis kebijakan dan inisiatif energi di masa lalu dan saat ini sesuai dengan konsep yang dielaborasi oleh Melly Caballero. Perbandingan fokus Indonesia pada ketahanan energi sebelum dan selama wabah COVID-19 akan memberikan gambaran yang jelas tentang bagaimana Indonesia mengamankan energi. Argumen utamanya tetap bahwa Indonesia sekarang berfokus pada keamanan sebagai keterjangkauan, bukan ketersediaan dan keberlanjutan. Ini karena, peningkatan tagihan listrik rumah tangga yang dicatat PLN, berbeda dengan aktivitas industri yang menurun membuat permintaan energi nasional melonjak. Kebijakan energi yang disebutkan dalam makalah ini mengacu pada peraturan dan inisiatif pemerintah dari Perusahaan Listrik Negara (PLN). Makalah ini juga akan mengenali masalah yang sedang berlangsung tentang distribusi energi yang tidak merata di luar jaringan Jawa dan melihat bagaimana masalah ini dipengaruhi oleh pandemi.

The dynamic shift of energy security can be seen both in the international and domestic scale. This paper will focus on the dynamic shift of energy security in Indonesia by analyzing past and current energy policies and initiatives according to the concepts elaborated by Melly Caballero. A comparison of Indonesia’s focus on energy security before and during the COVID-19 outbreak will give a clear picture in how Indonesia is securing energy. The main argument remains that Indonesia is now focusing on security as affordability instead of availability and sustainability. This is because of the increased household electric bill recorded by PLN in contrast to the decreasing industrial activities. The energy policies mentioned in this paper refers government regulations and initiatives from the state-owned electric company (PLN). This paper will also recognize the ongoing issue of unequal distribution of energy outside the Java grid and see how this issue is impacted by the pandemic.

UNATTACHED 212PB FRACTION IN THE WORKER’S BREATHING ZONE AT HIGH THORON CONCENTRATIONS

Classical aerosol physics predicts that it is impossible to observe noticeable values of the unattached fraction of decay products of thoron at typical concentrations of aerosol particles. The experimental data have shown that the unattached fraction of the thoron decay products in a monazite storage facility is in the range 0.3–0.6. This effect is caused by local increase in air exchange near the inlet of the sampling device at high 220Rn concentrations. It was found that a dynamic shift between the unattached and attached thoron decay products is also observed in the worker’s breathing zone at a high concentration of thoron. The 212Pb unattached fraction in worker’s breathing zone was ~0.4. It demonstrates that when evaluating inhalation exposure to the products of the decay of thoron, it is necessary to take into account the increase of the 212Pb unattached fraction in the worker’s breathing zone.
