Judul: Resiliensi Komunitas Miskin di Pedesaan Menghadapi Pandemi Covid-19
Abstrak: Pandemi Covid-19 yang terjadi sejak awal tahun 2020 sampai saat ini memberikan dampak buruk bagi kesehatan, sosial, dan ekonomi. Menghadapi gangguan akibat bencana ini komunitas harus mampu beradaptasi agar dapat bertahan hidup, terutama komunitas miskin yang merupakan kelompok rentan. Komunitas miskin merupakan komunitas yang tidak berdaya serta memiliki keterbatasan ekonomi. Ancaman besar akibat pandemi ini ialah akan meningkatkan kemiskinan akibat guncangan ekonomi dan pembatasan aktivitas. Tujuan penelitian ini akan mengkaji ketahanan komunitas miskin di pedesaan menghadapi pandemi yang ditinjau melalui kapasitas adaptasi dan tindakan kolektif komunitas. Metode yang digunakan adalah survei menggunakan instrumen kuesioner, observasi, dan wawancara mendalam. Pemilihan responden menggunakan teknik sample random sampling dan didapatkan sample sebanyak 40 responden. Hasil penelitian menunjukkan bahwa ketahanan komunitas miskin di pedesaan tidak terbangun karena komunitas tidak mampu beradaptasi dalam menghadapi pandemi dan tidak adanya upaya kolektif yang dilakukan untuk mengatasi permasalahan bersama selama pandemi. Komunitas cenderung mengandalkan bantuan dan dukungan eksternal dari pihak luar komunitas untuk bertahan menghadapi pandemi Covid-19., The Covid-19 pandemic that has occurred since the beginning of 2020 until now has had a negative impact on health, social and economy. Facing the disruption caused by this disaster, the community must be able to adapt in order to survive, especially the poor who are a vulnerable group. The poor community is a community that is powerless and has economic limitations. The big threat due to this pandemic is to increase poverty due to economic shocks and restrictions on activities. The purpose of this research is to examine the resilience of rural poor communities to face pandemics in terms of adaptive capacity and community collective action. The method used is a survey using a questionnaire instrument, observation, and indepth interviews. Selection of respondents using a random sampling technique and obtained a sample of 40 respondents. The results showed that the resilience of poor rural communities was not developed because the community was unable to adapt to the pandemic and there was no collective effort to overcome common problems during the pandemic. Communities tend to rely on external assistance and support from outside the community to survive the Covid-19 pandemic

Judul: Peran Pemimpin Lokal dan Aksi Kolektif dalam Resiliensi Komunitas Pedesaan Selama Pandemi COVID-19 (Kasus: Sebuah dusun di Kecamatan Belopa, Kabupaten Luwu, Sulawesi Selatan)
Abstrak: Pandemi COVID-19 yang telah menyebar hingga ke desa mengharuskan pemerintah dan warga komunitas memiliki kemampuan untuk mengurangi dampak kerugian dari pandemi COVID-19. Peran pemimpin dibutuhkan untuk menggerakkan aksi kolektif dalam membangun resiliensi komunitas selama pandemi COVID-19. Penelitian ini bertujuan untuk menganalisis peran pemimpin lokal dan aksi kolektif dalam resiliensi komunitas selama pandemi COVID-19. Penelitian ini menggunakan pendekatan kuantitatif dengan instrumen kuesioner yang dilengkapi oleh pendekatan kualitatif dengan wawancara mendalam dan observasi. Lokasi penelitian yakni di Dusun Kalobang, Desa Senga Selatan, Kabupaten Luwu, Sulawesi Selatan. Pemilihan responden menggunakan teknik simple random sampling dengan responden sebanyak 50 orang. Hasil penelitian menunjukkan tingginya tingkat peran pemimpin lokal memiliki hubungan yang kuat dengan tingkat aksi kolektif komunitas pedesaan selama pandemi COVID-19. Sedangkan tingkat aksi kolektif tidak memiliki hubungan dengan tingkat resiliensi komunitas pedesaan selama pandemi COVID-19. Namun, warga komunitas memersepsikan tingkat resiliensi komunitas berada pada kategori tinggi., The COVID-19 pandemic that has spread to villages requires the government and community members to have the ability to reduce the impact of losses from the COVID-19 pandemic. The role of leaders is needed to drive collective action in building community resilience during the COVID-19 pandemic. The purpose of this research to analyze the role of local leaders and collective action in community resilience during the COVID-19 pandemic. This research uses a quantitative approach with questionnaire instruments equipped with a qualitative approach with in-depth interviews and observations. The research location is in Dusun Kalobang, South Senga Village, Luwu Regency, South Sulawesi. The selection of respondents used a simple random sampling technique with 50 respondents. The results showed that the high level of role local leaders has a strong relationship with the level of collective action rural communities during the COVID-19 pandemic. Meanwhile, the level of collective action has not relation to the level of resilience rural communities during the COVID-19 pandemic. However, community perceive the level of community resilience as being in the high category.

Judul: Separation of Neodymium from U3Si2/Al Fuel Plate for Burn-Up Determination
Abstrak: Neodymium is a common fission product produced in nuclear fission reactions. Neodymium in this study was chosen as a burn-up indicator for U3Si2/Al fuel element plates because the neodymium isotope is a stable fission product with a fairly high yield. Some procedures were carried out to separate neodymium, starting with the separation of cesium isotopes (137Cs, 134Cs) through the precipitation method, then separation of uranium isotopes (235U, 238U) and plutonium isotopes (239Pu, 238Pu) with Dowex 1x8 ion exchange resin, and separation of neodymium (Nd), samarium (Sm), as well as cerium (Ce) with Dowex 1x4 ion exchange resin. The Cs recovery reached 99.95%. The U and Pu isotopes resulting from the separation are subjected to an electrodeposition process and the weight of each isotope can be measured with an alpha spectrometer. The separation results of Nd from Sm and Ce have been proven using an XRF spectrometer. The neodymium isotopes separation was corrected using the standard addition method, and an average total Nd content of 2.4 ppm was obtained in the PEB U3Si2/Al bottom solution. It is hoped that this separation method can be applied in determining burn-up of nuclear fuel.
