Published: January 2022

AbstractAccording to the World Giving Index, a study done by the Charities Aid Foundation that provides insights into the global trends of generosity, Indonesia has taken the top position of the chart and was named 2020’s most charitable country in the world. The notion of communality, consensus and collectivity, also known in Javanese as gotong royong or mutual assistance, a prominent characteristic associated with the traditional village life, appeared to also transpire within the global village. As we are universally connected through the digital world and are collectively experiencing a global pandemic where all art activities came to a halt, it is important to look further into how art adapted to these sudden changes and limitations of circumstances. Using a cultural studies approach and virtual ethnography data collecting, this paper will seek to examine how several online art initiatives try to embody the spirit of collectivity, using artworks as a tool of activism to help others survive the pandemic and at the same time reimagining the notion of gotong royong that can persist in the digital village that functions as a form of collective belonging to the concept of a nation. Aktivitas Seni sebagai Medium Gotong Royong di Era PandemiAbstrakMenurut World Giving Index, sebuah studi yang dilakukan oleh the Charities Aid Foundation yang memberikan wawasan tentang tren global kedermawanan, Indonesia menempati posisi teratas dan dinobatkan sebagai negara paling dermawan tahun 2020 di dunia. Gagasan komunalitas, konsensus dan kolektivitas, yang juga dikenal dalam bahasa Jawa sebagai gotong royong, karakteristik yang diasosiasikan dengan tradisi dan kehidupan wilayah desa, tampak juga terjadi di dalam desa virtual. Karena kita terhubung secara universal melalui dunia digital dan secara kolektif sedang mengalami pandemi global di mana semua kegiatan seni terhenti, penting untuk melihat lebih jauh bagaimana seni beradaptasi dengan perubahan dan keterbatasan keadaan yang terjadi. Dengan menggunakan pendekatan kajian budaya dan pengumpulan data etnografi virtual, makalah ini akan mencoba mengkaji bagaimana beberapa inisiatif seni daring mencoba untuk mewujudkan semangat kolektivitas, menggunakan karya seni sebagai alat aktivisme yang dapat membantu orang lain dalam kondisi pandemi, dan di saat yang sama kembali membayangkan gagasan gotong royong di desa digital sebagai usaha untuk menjadi bagian dari konsep sebuah bangsa.

Some FASSIP-01 experiments have done before, but those experiments show that the fluid flow in FASSIP-01 is not in optimal conditions because there are some errors happened and causes some losses. The second modification of FASSIP-01 rectangular loop has purpose to minimize losses happened in previous modification of FASSIP-01. The purpose of this research is to know the characteristics of flow and the trend of the data from the flow in FASSIP-01 mod.2 rectangular loop before do experiments. Simulations is done by using 2-dimensional images and varying the heating temperature at 353,15 K and 363,15 K and the cooler at temperatures of 278.15 K, 283.15 K, 288.15 K and 293.15 K. Based on the simulation results it is known that the velocity flow rate will increase if the temperature in the heating tank is increased, but will decrease if the temperature in the cooling tank is increased. The results of the calculation of the Reynold Number and Nusselt Number based on the velocity flow rate are 2973,668 the lowest and 5775,356 the highest and for the Nusselt number  obtained 17,36 and the highest is 28,091.
Kwota wolna od opodatkowania jako narzędzie polityki finansowej państwa - kierunki projektowanych zmian
Authors: Kopańska Anna , Dorosz Judyta
Published: January 2022

Kwota wolna od opodatkowania stanowi specyficzną preferencję podmiotową w podatku dochodowym od osób fizycznych. Z założenia minimum wolne od podatku pozwala odstąpić od opodatkowania osób fizycznych uzyskujących minimalne dochody. Powyższe jest równoznaczne z wprowadzeniem zerowej stawki opodatkowania dla podatnika, którego dochód nie przekroczy minimum wolnego od podatku w danym roku podatkowym.

Wysokość kwoty wolnej od podatku wpływa na wysokość wpływów z tytułu podatku dochodowego od osób fizycznych do budżetu państwa i jednostek samorządu terytorialnego. Jednocześnie wysokość minimum wolnego od opodatkowania ma bezpośredni wpływ na poziom dochodów osób o niskich dochodach, a dokładniej na wysokość zarobków oraz motywację do utrzymania czy też podjęcia pracy. Odpowiednia zmiana wysokości kwoty wolnej od opodatkowania ma wpływ na strukturę dochodów budżetowych w kierunku podatków pośrednich. Nie ulega wątpliwości, iż wzrost kwoty wolnej od podatku zwiększa siłę nabywczą ludności przez co pobudza popyt konsumpcyjny.

W przyjaznym dla obywateli systemie podatkowym kwota wolna od opodatkowania powinna być narzędziem długookresowej polityki fiskalnej oraz powinna stanowić narzędzie sprawiedliwości opodatkowania osób fizycznych, równocześnie nie powinna zagrażać stabilności systemu finansowego państwa i jednostek administracji samorządowej oraz możliwości wykonywania zadań w sferze publicznej.

Matthew 1:1–17: Cultural Subjugation of Women in Shona Communities in Zimbabwe: A Hermeneutical Study
Authors: Chabata Lovejoy
Published: January 2022

The space accorded women in the genealogy of Jesus Christ glowingly typifies the subordination of women in African communities generally. Appositionally, 42 men against five women are mentioned in the family tree of Jesus in Matthew 1:1–17. The domination of males in the lineage of Christ rebuts the theology of Jesus as “the seed of the woman” (Compton 2018, 1; Hamilton 2006, 30; Luther 1958, 192). The relegation of women to a silhouetted horizon in the ancestral lineage of Jesus typifies the manner in which Shona traditions in Zimbabwe peripheralise women in issues of property and inheritance (Kambarami 2006, 7; Ncube 1996, 9; Riphenburg 1997, 33). In this article, I interrogate the status of women in the Matthean lineage of Jesus in light of patriarchal suppression of women in inheritance and property rights in Zimbabwe.
