Abstract

Antioxidant is an essential compound to keep man’s health due to its function as radical scavenging. Curcumin analog  compounds can function as antioxidant (Sardjiman, 2000). The aim of the experiment was to find out the antioxidant activity of 2,.6-bis-(2’-furilidin)-cyclohexanone, 2,.5-bis-(2’furilidin)-cyclopentanone, and 1,.5-difuril-1.4-pentadien-3-one compounds, and the antioxidant activity of each compound against DPPH  radical with IC50 parameter as well as the correlation of compounds structure’s activities against antioxidant.  The antioxidant activity of curcumin analog compounds wereas tested against DPPH free  radical. The test was conducted in 5 series of concentrations by adding 4.0  ml test solutions with 1.0 ml DPPH. The antioxidant activity against free radical was measured usingwith spectrophotometer at 517 nm wavelength and determined for the IC50 value. The experiment employed rutin as positive control. The result of the experiment showed that curcumin analog compounds have antioxidant  activity with IC50 of rutin, 2,.6-bis-(2’-furilidin)-cyclohexanone, 2,.5-bis-(2’furilidin)-cyclopentanone, and 1,.5-difuril-1.4-pentadien-3-one as follows: 4.93 ppm, 22.73 ppm, 20.67 ppm, and 18.80 ppm  respectively. The highest antioxidant activity belonged to  1,.5-difuril-1.4-pentadien-3-one compound which is 18.80 ppm . Correlation of activity structure of the 3 compounds can be seen from the log p parameter and energy space of HOMO-LUMO.

Abstract

This study aims to explain the main character in the short story Lamb to the Slaughter by Roald Dahl. The attitude and characteristics of the main character Mrs. Mary Maloney and how the main character's personality is described in the story. The research uses several theories, such as character and characterization theory. personality theory. Character is a habit of the process of action that is carried out by individuals repeatedly, and characterization refers to the description of the author and the development of the character (Griffith, 1982: 29). There are three categories of characters according to William Kenney (1966:27), based on their function: characters are divided into several types, namely: main characters, secondary characters, and supporting characters. Characterization is the way a writer displays the personality of a character. Both direct and indirect characterizations are used to express characteristics. There are two types of characterization methods: direct and indirect which refer to research results. Keywords: Characteristics; Main Figures; Short Story.
