Investigation on enzymatic activity of rubber seed as source of plant lipase / Noor Fatiha Ahmad Bahrin, Harumi Veny, and Siti Zainab Che Mat
No full textRubber seed is a non-edible seed that is abundantly available and considers agricultural wastes. A potential lipase from rubber seed was examined based on the enzymatic activity and its application in the hydrolysis reaction. The enzymatic activity characterization study was determined based on p-nitrophenol release in the hydrolysis reaction. The initial evaluation showed that temperature and pH significantly influence the reaction. The optimum condition based on enzymatic activity for rubber seed was found at 30 ℃ and pH 8. The rubber seed lipase extract was then used in enzymatic hydrolysis reactions of rubber seed oil, palm oil, and canola oil. The highest FFA percentage of 63% was found from the rubber seed oil. The results indicate that rubber seed extract has shown its potential enzymatic activity. However, further studies need to be done to apply this rubber seed in various lipase catalysed reactions
Arena Wati as a Ship Captain: A Textual Analysis of Memoir Arena Wati Enda Gulingku
No full textArena Wati (1925-2009), is well-known by the Award of Malaysian National Laureate, which he received in 1988 for his outstanding contributions to the development of Malay literature. However he was also the captain of a sailing ship. His familial origins as sailors of Makassar, South Sulawesi, Indonesia have greatly influenced his writings. This article is a scrutiny of a work by Arena Wati in his capacity as a ship captain in relation to two functions, namely "as a trader" and "as a navigator". The approach to the text is through a qualitative content analysis, that is, interpretation and evaluation of messages associated with the text under study, namely, Arena Wati's memoir entitled Memoir Arena Wati Enda Gulingku (1991). Based on his successful implementation of both the functions mentioned, the analysis reveals that Arena Wati is an accomplished navigator. His knowledge of the maritime trade and the navigation he practiced establishes that Arena Wati's greatness as a ship captain is equal to his greatness as a fiction writer.
