Abstract

This study examines the representation of social awareness in Pramoedya Ananta Toer’s novel This Earth of Mankind, using Sheldon’s framework. Through qualitative descriptive analysis, the study identifies three dimensions of social awareness—cognition, social environment, and goals and motives—reflected in the characters of Minke, Nyai Ontosoroh, and Tuan de la Croix. The findings highlight Pramoedya’s critique of colonial social hierarchies and the awakening of native consciousness. Twelve data were collected to support the statement about social awareness and its aspects found in the novel. The results of this study are that there are three aspects of social awareness found in the novel This Earth of Humanity, namely cognition, social environment, and goals and motives. The cognition can be seen through Minke’s character, which is displayed through his disbelief in Astrology and superstition, his good process of absorbing information, and his way of thinking critically about the problems of the indigenous people. The social environment can be seen through social awareness of the backwardness of natives’ behavior and social awareness of native status towards Europeans. Goals and motives can be seen through the goals of Minke and Tuan de la Croix, who wanted to make the natives more advanced and developed, and Nyai Ontosoroh's goals for Annelies.

Abstract

Enzim α-amilase adalah enzim yang mengkatalisis hidrolisis ikatan α-1,4 glikosidik polisakarida menghasilkan dekstrin, oligosakarida, maltosa, dan D-glukosa. Penelitian ini bertujuan meningkatkan kestabilan enzim α-amilase hasil pemurnian dari Aspergillus fumigatus dengan penambahan gliserol. Aktivitas enzim ditentukan dengan metode Fuwa dan Mandels, sedangkan kadar protein ditentukan dengan metode Lowry. Hasil penelitian menunjukkan enzim hasil pemurnian memiliki aktivitas spesifik sebesar 1,377 U/mg meningkat sebanyak 8,1 kali dibandingkan dengan ekstrak kasar enzim yang memiliki aktivitas spesifik sebesar 0,170 U/mg. Enzim hasil pemurnian memiliki pH optimum 5,5; suhu optimum 55 °C; waktu paruh 133,26 menit. Enzim setelah penambahan gliserol 0,5; 1 dan 1,5 M memiliki pH optimum dan suhu optimum yang sama, yaitu pH 5,5 dan suhu 55 °C. Enzim setelah penambahan gliserol:  0,5 M memiliki waktu paruh 157,5 menit: 1 M memiliki waktu paruh 182,36 menit, dan 1,5 M memiliki waktu paruh 223,54 menit. Penambahan gliserol pada enzim α-amilase hasil pemurnian dari A. fumigatus dapat meningkatkan kestabilan enzim sebanyak 1,2-1,7 kali dibandingkan dengan enzim hasil pemurnian yang ditunjukkan dengan  peningkatan waktu paruh.https://jurnal.fmipa.unila.ac.id/analit/article/view/2684/1868
