Peran sentral tanah dalam menyokong pekerjaan konstruksi dan pendukung pondasi bangunan serta sebagai dasar pendukung seluruh beban di atasnya baik itu beban konstruksi maupun beban lalu lintas menjadikan analisis kekuatan tanah dasar sebagai tahapan penting dalam perencanaan konstruksi. Tanah timbunan untuk subgrade sangat dipengaruhi oleh daya dukung tanah. Beberapa parameter pengujian bisa menjadi gambaran untuk mengetahui daya dukung tanah, diantaranya California bearing ratio (CBR). Penelitian ini bertujuan untuk mengetahui sifat fisik dan mekanis pada tanah yang mempengaruhi daya dukung tanah untuk subgrade dan mengetahui laju perubahan nilai California bearing ratio (CBR) terhadap tingkat kepadatan pada tanah berbutir kasar. Penelitian ini menggunakan dua jenis sampel yaitu 70% butiran kasar (sand): 30% butiran halus dan 70% butiran kasar (5% gravel, 65% sand) : 30% butiran halus. Dimana pada masing-masing sampel tersebut menggunakan 5 benda uji dengan kadar air bervariasi yaitu 5%, 10%, 15%, 20% dan 25%. Adanya perbedaan kadar air yang pada masing-masing benda uji, menyebabkan nilai CBR yang diperoleh juga berbeda-beda. Pada sampel 1 diperoleh nilai CBR tertinggi dengan kadar air 15% yaitu 23,640% sedangkan pada sampel 2 diperoleh nilai CBR tertinggi dengan kadar air 15% yaitu 27,598%. Dengan demikian material ini dapat digunakan sebagai timbunan untuk subgrade karena nilai CBR yang diperoleh memenuhi syarat.

The grid-less Vortex Method has been developed as the tool for the analysis of two-dimensional (2D) and three-dimensional (3D) complex flows in various engineering applications. In the present study, unsteady flows around a slightly complex geometry (bare hull of an airship and body of an airship) at angles incidence α= 10°, 20°, and 30° were investigated by using the vortex method for a high Reynolds number, Re = 3.9105. The flow-pattern, velocity field, coefficient of pressure distribution on the bare hull and the surface of the airship body, and the aerodynamic coefficient were obtained from numerical calculations. A comparison of the numerical results with the experimental observations showed a good agreement.

If someone says "sorry" that means the person is doing "speech act of apologize". Speechact of apologize are needed in everyday life in order to facilitate communication andharmony in life. Apologizing in Japanese are divided into some part, we called as strategycommunication. They are the beginning of conversation, explaining the reason, apologizingand closing of conversation. We need use the strategy communication when apologizing toavoid the mistake and misunderstanding between speaker and partner. I hope that peoplewho are studying Japanese can use strategy of speech act of apologize in Japanese properly.

This research was aimed to investigate EFL students’ Self-Regulated Learning in writing. Self-Regulated Learning itself means the method that students take control in understanding of knowledge from the lecturer by conducting their own way in learning. The design of this study was quantitative with survey design to measure students’ academic self-regulation and self-regulation in writing class context. The population of this study were third semester students of English Department of University of Widya Gama Mahakam Samarinda, Indonesia, which consist of two classes with totally 37 students, who have studied English writing. Questionnaire were applied to measured two aspects; students’ academic self-regulation (77 items) and self-regulation concerning English writing subject (14 items), using Likert Scales. The result showed that 70% of students were able to motivate themselves to learn writing, do some efforts to engage the class, willingly to rehearse, elaborate and organize the lesson material by themselves, meanwhile 19% students have better self-regulation that make them conducted better effort to learn writing and accomplished better as well and 11% of them still struggle to survive in writing class. It proved by the mean of three indicator; Learning Activeness (3.18), Willingness to respond lecturer's suggestion (3.12), and Willingness to broaden writing skill (3.27). To sum up, it can be considered that students had good enough self-regulation in writing.

This research is aimed to investigate students development in terms of their English speaking proficiency, vocabulary and pronunciation aspects in context of English as Foreign Language. Furthermore, six EFL students who become subject of this research are Indonesian students who are originally stil studying at University of Widya Gama Mahakam Samarinda, Indonesia. In this case, those students had an experience of participating an international program what so called by Sea-Teacher, one of priority programs under Southeast Asian Ministers of Education (SEAMEO) which its homebase is in Bangkok, Thailand. Moreover, in dept interview was applied to those six students in order to find out what sort of effects they acquire after participating the Sea-Teacher program. As a result, all of exchange students experience development in terms of their oral proficiency, vocabulary as well as pronunciation.
