Handling of Mathematical Expression on Latin-to-Balinese Script Transliteration Method on Mobile Computing

Abstract

This study is aimed at analyzing the handling of mathematical expression on the Latin-to-Balinese Script transliteration method since there has not been studied yet. It is one of the ways to preserve the endangered local culture knowledge through the collaboration between Computer Science and Language discipline. Moreover, this study was conducted on mobile computing that supports ubiquitous learning. There are three aspects related, i.e.; 1) Balinese Language uses verbal mathematical expression rather than mathematical expression using the notation in its Balinese writing; 2) In transliteration case, the Latin text of mathematical expression using notation should be preserved to avoid complexity related to various verbal mathematical expressions (which they have the same meaning); and 3) The second aspect was limitedly handled by the supporting computer font, which in this case is Bali Simbar Dwijendra (SD) font, and special algorithm needed to be applied on them. This research added a certain perspective and strengthened the transliteration knowledge, as part of Balinese Language ubiquitous learning that supports Balinese Language education, which is a mandatory local subject from basic to high school in Bali Province. This analysis was conducted on pioneering Aksara Bali SD mobile application that receives Latin text input and outputs Balinese Script based on Bali SD font. Through the experiment, it's handling of mathematical expression gave good transliteration results since a special rule-based algorithm was applied.
