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.

Judul: Pelabelan Super Vertex Magic
Abstrak: Super vertex magic labeling is labeling on graph with is a set of edges mapped into and is a set of vertices mapped into . It has a vertex magic labeling in which and represents the size and order of the graph respectively. This manuscript proves that paths, cyclics, and disjoint union of cyclics have a super vertex magic labeling. There are four theorems to be discussed. The first theorem proves that path is super vertex magic if and only if is odd and . The second theorem proves that cyclic is super vertex magic if and only if is odd. The third theorem proves that bijection function from an edge set onto of graph can be extended to a super vertex magic labeling if and only if the set amount of edge label that incidents with a vertex in the graph, consists of sequential integers as many as vertices in the graph. The fourth theorem proves that disjoint union of the cyclics consists of cyclics with each cyclic has vertices is super vertex magic if and only if and are odd.
