Judul: The Changes in the Livelihood Structures and the Living Standards of Women-Headed Households during the Covid-19 Pandemic
Abstrak: Wabah Covid-19 telah ditetapkan menjadi pandemi dan persoalan kompleks global. Dalam merespon keadaan ini, pemerintah telah mengeluarkan berbagai kebijakan. Namun, kebijakan ini memberikan dampak terhadap kehidupan rumah tangga yang dikepalai perempuan. Dengan memfokuskan pada daerah yang memiliki sejumlah besar segmen populasi ini, penelitian bertujuan menganalisis perubahan struktur nafkah, perubahan taraf hidup, dan hubungan antara perubahan struktur nafkah dan perubahan taraf hidup. Kami secara sengaja memilih Desa Sukanagalih, Kecamatan Pacet, Kabupaten Cianjur karena terdapat banyak perubahan kondisi kehidupan rumah tangga yang dikepalai perempuan pada masa pandemi Covid-19. Metode yang digunakan adalah metode campuran dengan mengkombinasikan pendekatan kuantitatif dan kualitatif. Pemilihan responden menggunakan teknik proportional sampling dengan jumlah responden sebanyak 45 orang. Penelitian ini didukung dengan wawancara mendalam kepada informan yang dipilih secara sengaja. Hasil penelitian menunjukkan bahwa terjadi perubahan yang signifikan pada struktur nafkah dan taraf hidup serta terdapat hubungan yang lemah antara perubahan struktur nafkah dan perubahan taraf hidup rumah tangga yang dikepalai perempuan pada masa pandemi Covid-19., The Covid-19 virus outbreak has been declared a pandemic and is becoming a complex global issue. In response to this, the Indonesian government has issued many policies. But, these policies severely impacted marginalized women-headed households life. Zooming into an area of a significant number of this segment of population, we analyzed changes in livelihood structure, changes in living standards, and the relationship between the changes in the livelihood structure and living standards. We purposively choose Sukanagalih Village, Pacet Sub-district of Cianjur Regency because there are so many changes of women-headed households’ lives during the Covid-19 pandemic. This study used mix methods: a combination of quantitative and qualitative approaches. We selected 45 respondents following the proportional sampling technic. The structured interview was complemented with in-depth interview with purposively selected informants. This study indicates that there are significant changes in the livelihood structure and living standards. We also found a weak relationship between the changes in livelihood structure and changes in women-headed household living standards during the Covid-19 pandemic.

Judul: Gender and Household Livelihood Strategies Affected by the COVID-19 Pandemic (Case: Household of Industrial Workers Affected by Layoffs, Temporarily Laid off and salary cuts in Tangerang City).
Abstrak: Pandemi COVID-19 yang muncul di Indonesia memiliki dampak luas bagi bidang ketenagakerjaan yaitu adanya penerapan kebijakan oleh perusahaan terutama pada sektor industri. Pekerja buruh industri merupakan salah satu kelompok yang rentan sebelum adanya pandemi dan diperburuk dengan adanya pandemi yaitu kehilangan sumber nafkah utama akibat adanya pemutusan hubungan kerja, dirumahkan sementara, dan pemotongan gaji. Tujuan dari penelitian ini adalah menganalisis karakteristik, perubahan modal nafkah, serta gender dan strategi nafkah rumah tangga. Penelitian ini menggunakan pendekatan kuantitatif yang didukung dengan pendekatan kualitatif. Teknik pengumpulan data yang digunakan adalah teknik kuesioner dan wawancara mendalam. Hasil penelitian menunjukan bahwa terjadi perubahan modal nafkah pada rumah tangga pekerja buruh industri, baik perubahan yang menurun maupun meningkat.

Rumah tangga yang mengalami penurunan modal nafkah bergegas melakukan beragam strategi nafkah demi memenuhi kebutuhan rumah tangganya., The COVID-19 pandemic that emerged in Indonesia has a broad impact on the field of employment, namely the implementation of policies by companies, especially in the industrial sector. Industrial workers were one of the vulnerable groups before the pandemic and was exacerbated by the pandemic, namely the loss of their main source of income due to policies from the company in the form of termination of employment, temporary layoffs, and salary cuts. The purpose of this study was to analyze the characteristics, changes in living capital, gender and household livelihood strategies.

Judul: Elektrode Komposit Zeolit sebagai Biosensor Berbasis Tirosinase
Abstrak: Tyrosinase is a copper-containing oxidase, which catalyzes the first 2 steps in mammalian melanogenesis and responsible for enzymatic browning reactions. This study aims to develop and characterize tyrosinase biosensor of zeolite composite and its stability. The enzyme should be properly attached to the transducer for maintaining enzyme activity. Tyrosinase activity was monitored by L-DOPA as a substrate. The optimum conditions of tyrosinase activity obtained by respon optimizer were tyrosinase 50 U/mL and zeolite 150 mg/mL. Using of ferrocene as mediator and zeolite as the immobilization matrix on electrode increased the activity of tyrosinase. KMapp and Imaks app values of tyrosinase were determined by Lineweaver-Burk method, giving 6.04 mM and 6.42 mM, respectively. The electrode of zeolite as immobilizing matrix was relatively stable until 2 hours, the remaining tyrosinase activity was 87.45%
