THE RHETORICAL STRUCTURE AND COMMUNICATIVE STRATEGIES OF THESTUDENTS’ REQUESTS IN THE WEB DISCUSSION FORUM

This paper is to describe the rhetorical structure and the communicative strategies that students use in the web discussion forum of Ma Chung University. This web discussion forum allows the participants, especially students, to share their ideas, opinions about the current issues in the campus in the form of written texts. Among 11 students who get involved in discussing two issues, the campus bell and hair coloring, they are most likely to attend to directive based rhetorical structure when they have the same opinions. By contrast, representative based rhetorical structure becomes more obviously apparent when they have diverse opinions among themselves. In order to strengthen the perlocutionary force of the utterance, the students are also most likely to use some communicative strategies such as a colloquial and native language, abbreviation, capitalized letters and emoticon

On Multiscale Methods in Petrov-Galerkin formulation

In this work we investigate the advantages of multiscale methods in Petrov-Galerkin (PG) formulation in a general framework. The framework is based on a localized orthogonal decomposition of a high dimensional solution space into a low dimensional multiscale space with good approximation properties and a high dimensional remainder space{, which only contains negligible fine scale information}. The multiscale space can then be used to obtain accurate Galerkin approximations. As a model problem we consider the Poisson equation. We prove that a Petrov-Galerkin formulation does not suffer from a significant loss of accuracy, and still preserve the convergence order of the original multiscale method. We also prove inf-sup stability of a PG Continuous and a Discontinuous Galerkin Finite Element multiscale method. Furthermore, we demonstrate that the Petrov-Galerkin method can decrease the computational complexity significantly, allowing for more efficient solution algorithms. As another application of the framework, we show how the Petrov-Galerkin framework can be used to construct a locally mass conservative solver for two-phase flow simulation that employs the Buckley-Leverett equation. To achieve this, we couple a PG Discontinuous Galerkin Finite Element method with an upwind scheme for a hyperbolic conservation law

Policy Standardization Implementation Guarantying at the Private University in Semarang City

The purpose of this research is designed to describe and analyze the implementation of the quality assurance policy at a private college in the city of Semarang and the identification of those aspects that support and hinder the implementation of a quality assurance policy at a private University in the city of Semarang. As for specific targets to be achieved in the research is to formulate quality assurance policy implementation model for effective education (proposed model) and corresponding needs in supporting improved quality of education at Private Colleges in the city of Semarang. The study was designed with a qualitative research approach and use descriptive analysis. The analysis of the data collected is done after through interviews and observations directly in the field. Because it uses a qualitative approach then the data analysis processes in inductive data collection method in dept Interview, observation, documentation, and test the validity of library studies with data using two methods, namely the technique of triangulation and peer debriefing. The activity of this data analysis consists of, i.e., data reduction, data display, and conclusion drawing/verification. To test the design quality assurance policy implementation model at a private college in the city of Semarang using consultation with experts guarantee quality (peer debriefing) for evaluation and improvement be alternative models. The next stage of the evaluation with Focus Group Discussion (FGD) by presenting a quality assurance team of experts from several universities to discuss alternative models these models are proposed so that/later can be implemented at private colleges. The location of the research done at Private Colleges include: Dian Nuswantoro University Semarang (UDINUS), Republic Indonesia Semarang Teachers Union University (UPGRIS), a high school computer (STEKOM), Indonesia Cruise Academy (AKPELNI), the maritime high school (STIMART) and site Quality Assurance Agency on research at the private University

Perbandingan Kriptografi RSA dengan Base64

Kriptografi mempelajari teknik-teknik matematika yang berhubungan dengan aspek keamanan informasi, seperti kerahasiaan data, keabsahan data, integritas data, serta autentikasi data. Algoritma kriptografi merupakan langkah-langkah logis bagaimana menyembunyikan pesan dari orang-orang yang tidak berhak atas pesan tersebut. Sampai saat ini belum ada penyerangan terhadap RSA yang efektif. Namun apabila pemilihan parameter dan implementasi yang tidak tepat terhadap RSA dapat merupakan titik lemah sistem RSA sehingga rentan untuk diserang. Kriptografi transformasi Base64 banyak digunakan didunia internet sehingga media data format untuk mengirimkan data, ini dikarenakan hasil dari Base64 berupa plainteks maka data ini akan jauh lebih mudah dikirim, dibandingkan dengan format data yang berupa bineri. Sistem yang akan dibangun peneliti dalam pengamanan teks menggunakan algoritma RSA dan Base64, dimana kedua algoritma tersebut akan dibandingkan ukran dan waktu prosesnya untuk mencari yang mana algotitma terbaik. Kata kunci : Kriptografi, RSA, Base6

KONTRIBUSI IBU RUMAH TANGGA PEDAGANG SIRIH DALAM MEMBANTU PENDAPATAN KELUARGA DI KECAMATAN LAUBALENG KABUPATEN KARO

ABSTRAKNurlela,Ginting.2016. Kontribusi Ibu Rumah Tangga Pedagang Sirih Dalam Membantu Pendapatan Keluarga di Kecamatan Laubaleng Kabupaten Karo. Skripsi, jurusan pendidikan ekonomi, fakultas keguruan dan ilmu pendidikan, universitas syiah kuala. Pembimbing:Dr T.M. Jamil M.Si (2) Nana Suraiya, S.Pd, M.Pd.Kata Kunci : Kontribusi, pendapatan keluarga, pedagangPenelitian ini mengangkat masalah 1) berapa besar kontribusi pendapatan yang diberikan kepada keluarga? 2) berapa modal yang diperlukan untuk berdagang sirih? 3) faktor-faktor apa saja yang menyebabkan ibu rumah tangga berdagang sirih? Penelitian ini bertujuan untuk mengetahui besar kontribusi pendapatan yang diberikan kepada keluarga, untuk mengetahui jumlah modal yang diperlukan ibu rumah tangga pedagang sirih dalam menambah pendapatan keluarga, untuk mengetahui faktor-faktor yang menyebabkan ibu rumah tangga berdagang sirih. Pendekatan yang digunakan dalam penelitian ini adalah pendekatan kualitatif dengan metode deskriftif. Subjek penelitian ini adalah ibu rumah tangga pedagang sirih di Kecamatan Laubaleng Kabupaten Karo sebanyak 20 orang, objek penelitian ini adalah pendapatan ibu rumah tangga pedagang sirih. Pengumpulan data dilakukan dengan teknik penelitian pustaka, observasi dan wawancara. data penelitian diolah dengan menggunakan rumus rata-rata (x ?) dan rumus persentase (%). Hasil penelitian menunjukkan bahwa kontribusi yang diberikan oleh ibu rumah tangga pedagang sirih kepada keluarganya adalah 81,9%. Faktor yang menyebabkan ibu rumah tangga berdagang sirih karena pendapatan suami yang minim, ingin menggantikan suami mencari nafkah, ingin punya penghasilan sendiri. Modal yang dibutuhkan responden paling tinggi adalah Rp 1.000.000 , dan yang terendah adalah Rp 200.000 perharinya
