Communication gap because of linguistic difference and unavailability of specific learning materials become a problem of foreign workers working in Indonesia. A specific research that develops IFL learning materials to overcome these problems is needed. This study aims to develop and improve the quality of available IFL materials. Methodology used here is Research and Development, combining quantitative-qualitative approaches. The result of this study is: 1) M E D I A as a new framework learning materials with humanistic approach that presents multicultural domestic foreign workers’ characters bound by a shared narrative on linguistic problems within business communication realm; and 2) M E D I A as mnemonic technique to embody those multicultural characters and values into teaching materials’ books namely BIPA Business Communication.

The problem of Indonesian language errors among students is of particular observation. This problem becomes an important concern for students majoring in journalism because one day the graduates will become journalists. A language error filtering application has been developed that can be used quickly and accurately in journalists’ work. This application, which involves statistical analysis, computational language, and artificial intelligence, is named U-Tapis. This study was aimed at finding out the feasibility and effectiveness measures of the U-Tapis model by focusing on the language of students’ journalistic works such as opinions, news items, and news articles. The study involved 30 students majoring in Journalism, a private university in Jakarta, Indonesia. It was found that the students’ error rate decreased after the use of the model. It can be concluded that, in addition to eligibility which reaches 92.31%, the U-Tapis application can help effectively increase students’ proficiency in the use of the Indonesian language.
