Perancangan smart connector helm dan automatic GPS bertujuan untuk membantu komunikasi antar pengemudi dan sebagai penunjuk arah yang berbasis internet. Alat bantu komunikasi ini terpasang di helm dan terkoneksi dengan smartphone. User dapat berkomunikasi antar Helm dengan Helm yang lain melalui jaringan wireless sinyal radio dari HT. Helm juga terhubung pada smartphone menggunakan bluetooth. Smartphone berfungsi sebagai penunjuk arah dengan adanya GPS dan aplikasi pendukung yang dibuat. Selain itu, pengemudi juga dapat menerima telfon dan mendengarkan musik dengan helm tanpa harus memegang smartphone. Metode perancangan menggunakan pendekatan water fall. Hasil rancangan diperoleh: (a) kerangka Helm yang digabungkan dengan headset, bluetooth, HT; (2) Rancangan aplikasi dari smartphoneyang terhubung dengan helm.

This study aims to build Android-based Markerless Augmented Reality as a learning media in the Construction field, specifically Bridge material for vocational students. This study applies the Extreme programming method, which consists of the Planning, Design, Coding, and Testing stages. The developers and potential users performed the tests. The Functional Usability test results using Black-Box testing reveal that all features in the application can operate successfully. In terms of compatibility, the application is declared very suitable for use. The application has proven successful in running on several kinds of Android smartphones with different versions and screen resolutions. Meanwhile, in terms of Usability, the application acquires an eligibility percentage of 84.2%. Users find it easy to operate the application since they can immediately run 3D objects wherever they are, without being limited by the presence of markers. They consider being freer to run AR applications. However, the Markerless application that has been built can only be operated on Android smartphones version 7.0 and above.

The objectives of this research were: (1) producing Android-based AR products in the form of a Wood Field Laboratory Work module in Department of Civil and Planning Engineering Education, Faculty of Engineering UNY to facilitate students’ visualization abilities; (2) knowing the quality of Augmented Reality products for the Wood Field Laboratory Work module so that it is suitable for use by students and teaching staff; and (3) addressing the learning problems that have so far been present in the Wood Field Laboratory Work. The method used was the Software Development Life Cycle software development model which was described by the v-model waterfall. The v-model included: (1) the stage of specification of user requirements; (2) system architecture design; (3) designing components; (4) writing program codes; and (5) testing. The test results using ISO 25010 indicated that the application of learning media was stated to be very feasible in functional suitability, compability, and usability aspects. While from the performance efficiency aspect, the application was considered feasible because there was no memory leak on the device that run it, and CPU usage by five different devices reaches 10%, which is still below the safe limit (15%).

Rangkaian penyearah gelombang penuh adalah penyearah yang mengonversikan kedua siklus positif dan negative dari sinyal AC menjadi sinyal DC yang berdenyut. Rangkaian penyearah gelombang penuh juga bisa dibuat dengan memakai trafo centre tapped.

The purpose of this study is to describe the dynamics of the career development on each stage, starting from growth, exploration and establishment in Batik makers of Giriloyo. This study employs case study qualitative research methods, and involves three women who worked as batik maker. Data analysis was performed by data reduction, data presentation, and conclusion drawing. From this research it is revealed that participants did not fulfill the developmental tasks at all three stages as a whole and they went through stages of career development sequences and period that is differed from the established theory of career development. It is also revealed that the participants experienced dissatisfaction with the wages. However, in the other hand they felt proud to be able to take part on their community and wishes to continue to make batik as long as they are physically able. The results of the study led researchers to recommend early career recognition by families, schools and communities.
