Judul: Analisis Hubungan Modal Sosial dengan Kesejahteraan Anggota Kelompok Pedagang di Kawasan Wisata Pantai Widuri (Kasus: Kelompok Pedagang Pantai Sirkuit Widuri Pemalang)
Abstrak: Pandemi Covid-19 berdampak pada sektor ekonomi, salah satunya penurunan pendapatan pedagang karena perubahan pada pola kegiatan nafkahnya yang dibatasi. Penelitian ini akan mengkaji terkait dampak pandemi Covid-19 terhadap kesejahteraan pedagang. Kesejahteraan tersebut dapat diwujudkan melalui dibentuknya suatu kelompok pedagang, bagaimana suatu kelompok dapat beradaptasi pada saat bencana yang ternyata didukung beberapa faktor salah satunya adalah modal sosial. Tujuan dari penelitian ini adalah untuk menganalisis hubungan modal sosial dengan kesejahteraan anggota Kelompok Pedagang Pantai Sirkuit Widuri. Metode yang digunakan dalam penelitian ini adalah metode survei dengan pendekatan kuantitatif yang didukung data kualitatif. Responden dalam penelitian ini berjumlah 55 orang yang merupakan anggota Kelompok Pedagang Pantai Sirkuit Widuri. Hasil penelitian menunjukkan terdapat hubungan yang cukup kuat antara modal sosial dengan kesejahteraan, terutama karena didasari oleh unsur modal sosial yang dominan yaitu kepercayaan.

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: Heterologous Expression Of Endo-Β-Xylanase From Bacillus Pumilus Strain Bcrs-01 In Escherichia Coli.
Abstrak: Xylanases are glycoside hydrolase family 11 which depolymerise xylan in the plant cell wall, the most excessive form of hemicellulose. Endo-β-xylanases (EC 3.2.1.8) are most important to breakdown β-1,4-glicoside bond of xylan to produce disaccaride xyloolygosaccaride (XOs) and xylose (monomer). Bovine rumen fluids have potential to obtain endo-β-xylanase produced of bacteria. The objectives of this study were to obtain xylanase producing bacteria and to express xynA gene encoding endo-β-xylanase from bacterium in Escherichia coli. Twenty nine isolate bacteria have been succesfully isolated from bovine rumen fluid in agar medium containing birchwood xylan. Isolate BCRS-01 bacterium was previously screened for the high production of xylanase. Based on 16S rRNA gene sequence analysis, BCRS-01 showed high similarity (99%) to Bacillus pumilus (accession number NR043241). The crude xylanase had optimal activity at 55oC, pH 7.0. Furthermore, the crude xylanase exhibited broad pH stability from 4.0 to 10.0 and remained more than 60% and 40% of its activity after incubation at pH 4.0 until 10.0, respectively for 60 min. It also showed a stability at temperature 25-50oC since it retained 80% and 50% of its activity when incubated at 50oC or 30 and 60 min, respectively. The xylanase activity was strongly inhibited by Ca2+ and Cu2+ at concentration 10 mM, and as little as 1 mM for Mn2+. Therefore, this xylanase has potentially used as additive feeds in animal feed industry. The DNA sequence xynA gene encoded endo-β-xylanase was amplified and cloned into the expression vector pET-15by under the control of T7 promoter. The recombinant protein had succesfully expressed in Escherichia coli BL21 (DE3) pLysS. A protein recombinant of approximately, 26.7 kDa was observed on the SDS-PAGE analysis. Crude extract of recombinant endo-β-xylanase demonstrated activity of enzyme at 56 U mL-1 using birchwood xylan as a substrate at 55oC for 10 min.
