Judul: Social Capital, Collective Action, and Resilience of Small Trader Communities in Post Covid-19 Pandemic Tourist Areas
Abstrak: Pandemi Covid-19 telah melanda dunia yang membuat perubahan besar di berbagai sektor, tanpa terkecuali sektor pariwisata teritama pedagang kecil yang ada di dalamnya. Pada masa pascapandemi covid-19 seperti ini para pedagang kecil di daerah wisata perlu beradaptasi untuk dapat mempertahankan usahanya. Maka dari itu, tujuan penelitian ini dilakukan untuk melihat peranan modal sosial dan aksi kolektif dalam resiliensi komunitas pedagang kecil di daerah wisata pada masa pascapandemi covid-19. Penelitian ini dilakukan di Taman Wisata Alam Gunung Pancar dengan mengguunakan metode survey melalui kuesioner dan wawancara mendalam terhadap 40 responden secara sensus. Hasil penelitian menunjukkan modal sosial dan aksi kolektif cukup berperan dalam resiliensi komunitas pedagang kecil di daerah wisata. Dengan modal sosial yang pedagang kecil miliki, mereka dapat melakukan aksi kolektif meskipun masih terbatas pada aksi yang berkaitan dengan berdagang saja. Selain itu, saat ini mayoritas pedagang kecil belum dapat resilien dalam hal perekenomian karena keterbatasan modal yang mereka miliki dan sepi nya pengunjung yang datang ke lokasi wisata. Hal tersebut yang membuat mereka belum dapat menciptakan kegiatan ekonomi baru yang dapat meningkatkan perekonomian mereka., The Covid-19 pandemic has hit the world which has made major changes in various sectors, without exception the tourism sector, especially the small traders in it. In the post-Covid-19 pandemic period like this, small traders in tourist areas need to adapt to be able to maintain their business. Therefore, the purpose of this research was conducted to see the role of social capital and collective action in the resilience of small trader communities in tourist areas during the post-Covid-19 pandemic. This research was conducted in Gunung Pancar Nature Tourism Park using a survey method through questionnaires and in-depth interviews with 40 respondents by census. The results showed that social capital and collective action play a role in the resilience of the small trader community in tourist areas. With the social capital that small traders have, they can take collective action even though it is still limited to actions related to trading only. In addition, currently the majority of small traders have not been able to be resilient in terms of the economy due to the limited capital they have and the lack of visitors who come to tourist sites. This makes them unable to create new economic activities that can improve their economy.

Judul: Community Resilience Around Nature Tourism Situ Gunung in the Era of COVID-19 Pandemic
Abstrak: Pandemi COVID-19 telah menyebabkan kerugian pada sektor pariwisata dan masyarakat sekitarnya, termasuk masyarakat sekitar kawasan wisata alam Situ Gunung. Adaptasi diperlukan masyarakat untuk mencapai resiliensi. Penelitian ini bertujuan untuk menganalisis persepsi masyarakat terhadap dampak, strategi adaptasi dan strategi mitigasinya dalam situasi pandemi COVID-19. Metode yang digunakan adalah survei rumah tangga dengan menggunakan kuesioner dan wawancara berdasarkan metode penentuan sampel dengan tabel Isaac dan Michael pada tingkat kesalahan 10%. Hasil penelitian menunjukkan bahwa pandemi COVID-19 telah berdampak ekonomi pada kehidupan masyarakat namun tidak menimbulkan dampak sosial. Kapasitas adaptasi masyarakat masih rendah, strategi adaptasi dilakukan oleh masyarakat dengan kondisi perekonomian rentan berdasarkan karakteristik pekerjaannya. Strategi mitigasi sudah dimiliki masyarakat namun masih dalam inisiatif di tingkat rumah tangga, The COVID-19 pandemic has caused losses to the tourism sector and surrounding communities, including the communities around the Situ Gunung natural tourism area. Adaptation is necessary for society to achieve resilience. This study aims to analyze people's perception of the impact, adaptation strategy, and mitigation strategy in the situation of the COVID-19 pandemic. The method used is a household survey using questionnaires and interviews based on the determining samples method with Isaac and Michael tables at a 10% error rate. The results showed that the COVID-19 pandemic has had a negative economic impact on people's lives but has no negative social impact. The adaptation capacity of the community is still low, the adaptation strategy is carried out by people with vulnerable economic conditions based on the characteristics of their job. The community, particularly at a household level, already has mitigation strategies.

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.
