The Magic of Howl’s Moving Castle: An Analysis of Character Development in a Fantasy Novel

The present study aims to examine the influence of magical events on the development of the major character in the novel Howl’s Moving Castle by Diana Wynne Jones. The present study uses qualitative approach, particularly descriptive qualitative method. The data were collected by critically selecting the words, phrases, and sentences that reflect events with magical happenings. In analyzing the data, this study employs Nikolajeva’s (1988) magic laws and Tolkien’s (1966) functions of fantasy. The analysis reveals that the magical events influence the development of the main character through the magic laws, which portray certain functions of fantasy. The magic law that dominantly appears in the novel is consistency (i.e., the idea that the secondary world has rules that must be obeyed). Meanwhile, in terms of functions of fantasy, recovery (i.e., recapture the fundamental vision of things) becomes the dominant function primarily shown. The findings of the present study also indicate that, in the fantasy genre, the development of the character is triggered by the elements of surprise and the element of wonder presented in the novel.

The Legitimation Construction in Regent of Garut’s Statements on His Unregistered Marriage: A Critical Discourse Analysis

Legitimation is one form ofthe social actionswhichis often done eventhough it isprobably less recognized. The present study examines the legitimation construction by the Regent of Garut and also the ideologies underlying the legitimation. It uses van Leeuwen’s (2008) framework regarding discursive construction of legitimation under the theory of Critical Discourse Analysis. This study is largely qualitative, but some quantification is employed to support the description. The collected data are in the form of statements delivered by Regent of Garut related to his unregistered marriage to a young girl. The data are analyzed in the unit of clause to reveal the legitimation construction in the texts. This study finds that from four major types of legitimation asserted by van Leeuwen (2008),only three types of legitimation are evidenced in the texts, i.e. rationalization (44.44%), authorization (44.44%), and moral evaluation (11.11%). Hence, the Regent of Garut’s actions in the texts are strongly legitimized through the logical explanation to support the unregistered marriage, supported by referring to high status as the basis of the actions, and the reference to moral value of humanity to avoid adultery. The ideologies underlying the legitimation are feudalism and masculinism.Keywords: Critical Discourse Analysis, Legitimation, Regent Of Garut, Unregistered Marriage, Ideology

FEASIBILITY OF CARPOOLING SCHEME DEVELOPMENT IN BANDUNG CITY FROM THE PERSPECTIVE OF TRAVELER PREFERENCES

The imbalance between supply and demand in Bandung City transport system has been the cause of the declining of this city transport performance. Supply approach by increasing road network capacity is considered as no longer effective due to limited developable road space. Demand approach seems to be a prospective solution to the problem. Among others, carpooling is considered as a promising scheme to reduce traffic volume by increasing average vehicle occupancy rate. The scheme is developed by attracting some travelers whose trip destination are in one corridor to join the same vehicle. This research figures out the feasibility of the implementation of carpooling scheme from the traveler preferences point of view. Based on Arcamanik Residential Area, Bandung City, the result of the research shows that this scheme is potential to be implemented with the percentage of respondent willingness to change mode in the beginning is 93%. However, after ride matching was introduced, respondents willing to join this scheme decline to 71% on leaving and 79% on the way back home. This research furthermore identifies some constraints in fulfilling traveler preference on carpooling scheme. The constraints are on the point to point pick-up system and walking distance preference that cannot totally be fulfilled
