Judul: Bantuan Sosial, Persepsi terhadap Bantuan, dan Konflik Sosial di Masa Pandemi Covid-19 (Studi Kasus Bantuan Sosial COVID-19 di Desa Klampok Kecamatan Wanasari Kabupaten Brebes Provinsi Jawa Tengah)
Abstrak: Bantuan Sosial, Persepsi terhadap Bantuan, dan Konflik Sosial di Masa Pandemi Covid-19 (Studi Kasus Bantuan Sosial COVID-19 di Desa Klampok Kecamatan Wanasari Kabupaten Brebes Provinsi Jawa Tengah). Dibimbing oleh Rilus A. Kinseng. Pandemi COVID-19 telah mengubah berbagai aspek kehidupan, termasuk aspek ekonomi. Krisis ekonomi akibat pandemi COVID-19 membuat pemerintah pusat dan pemerintah daerah mengeluarkan sejumlah bantuan sosial untuk diberikan kepada masyarakat yang terdampak COVID-19. Namun bantuan sosial COVID-19 melahirkan masalah sosial. Tujuan penelitian ini adalah menganalisis bantuan sosial yang diberikan selama pandemi COVID-19, respon masyarakat terhadap bantuan sosial COVID-19, hubungan karakteristik individu dengan persepsi terhadap bantuan sosial COVID-19, dan konflik sosial terkait bantuan sosial tersebut. Metode penelitian yang digunakan yaitu pendekatan kuantitatif (survei) dan pendekatan kualitatif (wawancara mendalam). Jumlah responden penelitian adalah 30 orang yang didapat melalui tenik sampel acak sederhana. Jumlah informan 3 orang yang diambil melalui teknik purposive. Hasil penelitian ini mengungkapkan bahwa bantuan sosial COVID-19 dinilai telah membantu masyarakat karena kebermanfaatan, kesesuaian, serta kemudahannya. Konflik sosial yang terjadi di Desa Klampok ialah perseteruan antara seorang warga dengan pemimpin tingkat RT, di mana warga tersebut menilai bantuan sosial COVID-19 tidak tepat sasaran. Konflik tersebut disebabkan oleh kecemburuan sosial, jumlah kuota bantuan sosial yang terbatas, dan data penerima bantuan yang tidak valid. Penelitian ini juga menunjukkan tidak ada korelasi antara karakteristik individu dengan persepsi masyarakat terhadap bantuan sosial COVID-19. Kata kunci: bantuan sosial COVID-19, karakteristik individu, konflik, persepsi., Social Assistance, Perceptions of Social Assistance, and SocialConflicts during the Covid-19 Pandemic (Case Study of COVID-19 Social Assistance inKlampok Village, Wanasari District, Brebes Regency, Central Java Province). Supervised by Rilus A. Kinseng. The COVID-19 pandemic has changed various aspects of life, including the economic aspect. The economic crisis due to the COVID-19 pandemic has forced the central government from the regional government to issue a number of social assistance to be given to people who provide COVID-19. However, the COVID-19 social assistance gave rise to social problems. The purpose of this study was to analyze the social assistance provided during the COVID-19 pandemic, the community’s response to the COVID-19 social assistance, the correlation between individual characteristics and perceptions of the COVID-19 social assistance, and social conflicts related to the social assistance. The research method used is a quantitative approach (survey) and a qualitative approach (in-depth interviews). The number of research respondents is 30 people obtained through a simple random sample technique. The number of informants is 3 people which is done through a purposive technique. The results of this study reveal that COVID-19 social assistance has helped people who are considered useful, appropriate, and easy. The social conflict that occurred in Klampok Village was a feud between a resident and the leader of the neighborhood unit level, in which the residents assessed that the COVID-19 social assistance was not right on target. The social assistance conflict that occurred in Klampok Village was caused by social jealousy, the limited number of social assistance quotas, invalid data from beneficiaries. This study also shows that there is no correlation between individual characteristics and community perceptions of COVID-19 social assistance.

Judul: Kohesi sosial dan aksi kolektif komunitas miskin perkotaan selama pandemi COVID-19
Abstrak: Salah satu elemen kunci keberhasilan dalam menghadapi pandemi COVID-19 di Indonesia adalah dengan membangun kerjasama. Kerjasama antara anggota komunitas adalah bentuk dari adanya kohesi sosial. Resiliensi komunitas dihasilkan dari kohesi sosial yang mendorong aksi bersama antar warga untuk mengurangi dampak bencana. Penelitian ini bertujuan menganalisis hubungan kohesi sosial dan aksi kolektif pada komunitas miskin perkotaan selama pandemi COVID-19 dengan menggunakan pendekatan kuantitatif melalui kuesioner dan didukung data kualitatif menggunakan wawancara mendalam. Lokasi penelitian ini adalah sebuah RW di Kecamatan Bogor Barat, Kota Bogor yang melibatkan 60 responden melalui metode proportional simple random sampling. Hasil penelitian menunjukkan bahwa walaupun komunitas miskin memiliki kohesi sosial yang sedang, namun mereka mampu memiliki aksi kolektif yang tinggi selama pandemi COVID-19, meskipun lebih rendah dibandingkan dengan aksi kolektif sebelum pandemi. Kohesi sosial dan aksi kolektif komunitas miskin perkotaan memiliki hubungan yang lemah. Kepemimpinan merupakan salah satu faktor yang berperan dalam tingginya aksi kolektif komunitas miskin perkotaan selama pandemi COVID-19., One of the key elements of success in dealing with the COVID-19 pandemic in Indonesia is to build cooperation. Cooperation between community members is a form of social cohesion. Community resilience results from social cohesion that encourages joint action among residents to reduce the impact of disasters. This study aims to analyze the relationship of social cohesion and collective action in urban poor communities during the COVID-19 pandemic using a quantitative approach through questionnaires and supported by qualitative data using in-depth interviews. The location of this research is an RW in West Bogor District, Bogor City which involves 60 respondents through the proportional simple random sampling method. The results show that although poor communities have moderate social cohesion, they are able to have high collective action during the COVID-19 pandemic, although lower than collective action before the pandemic. Social cohesion and collective action of urban poor communities have a weak relationship. Leadership is one of the factors that play a role in the high collective action of the urban poor community during the COVID-19 pandemic.

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.
