Indonesian-to-Javanese Machine Translation

Javanese is a multi-level language; it comprises four speech levels used to convey local politeness. However, the negative tendency is detected regarding the use of Javanese speech levels among teenagers. They prefer to use the Indonesian national language (bahasa Indonesia, BI) because of the Javanese speech level complexity. A combination of statistical and memory-based machine translation is designed by the authors to help Javanese youths in translating between both languages. The evaluation shows that translating speech levels of Javanese to Indonesian is more accurate than translating in the opposite direction, as revealed by the average accuracy (A) of 0.83 for Javanese-Indonesian translation and 0.68 for the other direction. Index Terms—Indonesian, Javanese speech levels, machine translation.

MACHINE TRANSLATION WITH JAVANESE SPEECH LEVELS’ CLASSIFICATION

A hybrid corpus-based machine processing has been developed to produce a proper Javanese speech level translation. The developed statistical memory-based machine translation shows significantly accurate results. Integration of an automatic text classifier and an expert system is proposed to help Javanese in classifying the speech levels used for a specific interlocutor. Javanese rule-based expert system is designed while naive Bayes classifier is selected after outperforming simple logic probability approach. As a result, the average of translation accuracy (72.3%) indicates that the integrated intelligent interfaces could effectively solve the Javanese language pragmatic translation problems.

Stand-Alone Data Logger for Solar Panel Energy System with RTC and SD Card

In this research stand-alone data logger device that can be used for measuring solar panel power characteristics is introduced. With RTC and SD Card installed on the device, the energy produced by solar panel is measured, then data are stored in CSV format that is compatible with MS Excel. Stand-alone feature makes it suitable for monitoring solar panel systems installed on remote area. Research result exhibits that all device sub systems are working perfectly. Voltage sensor convert the output voltage range of solar panel 0-24V to suitable voltage for microcontroller 0-5V. Real Time Clock (RTC) is able to show real time hours, minute and seconds of every measurements. Current sensor could measure the current with similar result compared to standard lab instruments. Despite data stored to SD Card, a 16&2 LCD display real time measurement results. Overall, the device works very well as if standard data logger instrument, but featuring real time monitoring and computer compatibility data.

Design of Web-based Lightweight Interactive Multimedia for Distance Learning

Electronic learning based on Information and Communication Technology is one of the backbone behind the success of distance learning because it is actually able to save cost, time, and resources. To optimize the quality of this learning, more variety and interactive content with the support of multimedia elements (such as text, images, animations, sounds and video) is required. This research proposes a design of web-based lightweight interactive multimedia application combined with a game approach to support distance learning. This design employs web technologies based on pure HTML5, CSS3, and AJAX scripting that offer rich interactivity and lightweight performance. This research produces an interesting and fun learning application design that able to motivate students to self-learning.

The Linkage between Vocational High School Cooperation with Industries in field of Information Technology in Malang

Developing potential human resources is every nation’s dream through quality education for empowering them for global competition. Skills and knowledge are recognized engines of economic growth and social development in any nation. TVET holds the master key for achieving this growth because it is driven by wheels of training skilled and entrepreneurial workforce needed in workplace with changing technologies as it is concerned with the acquisition of knowledge and skills ready for work. The purpose of this study is to find out the relationship between vocational high schools (SMK) cooperation with industries in the field of I.T in Malang City. This study was conducted in (4) public vocational high schools selected with simple random sampling method with 32 participants. Mixed method was used in data collection with school management and I.T teachers as subject. The results indicated that cooperation between vocational high schools with industries has great impact on the quality of vocational education as seen in the strong positive relationship of this research variables. The common cooperation type that existed were: Internship placement, job recruitment, on-job training.
