Using Story Circle to Improve Students' Ability in Writing Narrative Text

This study aims to discuss one way of solving the problems of students in writing narrative texts, namely by using Story Circle. In this activity, students were divided into several groups and then the teacher read one of the narrative texts in the form of fairy tales, fables or legends that they have never known before. They rewrote the text they had heard before in accordance with the generic structure and language features found in the narrative text, but with different versions according to their imagination. After they wrote the first few sentences of the story on the paper they had each, the students gave the paper to a colleague on their left. Then, their colleagues added the next sentence based on the idea of the story that had been written before. This activity continued until they completed the complication section of the story. When the paper returned to the real owner, the student wrote down the resolution. Activities Story Circle is expected to be one of the variations of learning to write in the class so that students are able to pour their ideas properly and precisely, especially in English. In addition, through this technique, students can creatively and freely develop story ideas

Development of nano-structured titanium oxide thin films using a gas carving technique

A method is developed for producing nano-structured titanium oxide thin films using H2 gas interaction with titanium thin film at a high temperature. These nano-structured thin films have been formed on a quartz crystal substrate. Titanium (Ti) thin films were deposited on the quartz crystal using a RF magnetron sputterer. The samples were placed in the oven at 500-800°C for 5 hours. The gas mixture of 1% H2 in N2 was introduced in the oven. The process of Ti annealing in the presence of H2 carves Ti films into nano-structure shapes. The process is a gas-solid interaction. Thin films were characterised using Scanning Electron Microscopes (SEM) and X-Ray Diffraction (XRD) technique. The nano structures formed have dimensions in a range of 25nm - 150nm obtained after gas carving

The method utilized in this study is descriptive. The subjects of this research were the teachers and students of social science. The results obtained were the ability of teachers to plan the first learning cycle 4.1, the second cycle 4.6 and the third cycle 4.8, with an increase 0.5 from the first cycle to the second cycle and 0.2 of the second cycle to the third cycle. The ability of teachers to implement the first learning cycle was 3.5, 4.2 at the second cycle and 4.4 in the third cycle, with 0.7 increase from the first cycle to the second cycle, and 0.2 from the second cycle to the third cycle. Students\u27 activity in the first cycle was 63.1%, 75.4% in the second cycle and 84.6% in the third cycle, with 12.3% increase from the first cycle to the second cycle, and 9.2% increase from the second cycle to the third cycle. Based on those facts, it is proven that the application of Think Pair Share increases the teachers\u27 ability in planning and implementing the lessons and students\u27 activity

Nonlinear electrokinetics at large voltages

The classical theory of electrokinetic phenomena assumes a dilute solution of point-like ions in chemical equilibrium with a surface whose double-layer voltage is of order the thermal voltage, kBT/e=25 mV. In nonlinear 'induced-charge' electrokinetic phenomena, such as ac electro-osmosis, several volts ≈100kBT/e are applied to the double layer, and the theory breaks down and cannot explain many observed features. We argue that, under such a large voltage, counterions 'condense' near the surface, even for dilute bulk solutions. Based on simple models, we predict that the double-layer capacitance decreases and the electro-osmotic mobility saturates at large voltages, due to steric repulsion and increased viscosity of the condensed layer, respectively. The former suffices to explain observed high-frequency flow reversal in ac electro-osmosis; the latter leads to a salt concentration dependence of induced-charge flows comparable to experiments, although a complete theory is still lacking.National Science Foundation (U.S.) (Grant No. DMS-0707641)United States.

Pembuatan Program Perataan Parameter Jaring Poligon Dengan Menggunakan Visual Basic for Application (VBA) Microsoft Excel

Least square method is one method most popular to problem-solving count flattening. The ordinal least quadrat in cases of the count of geodesy which simple, e.g. cutting measurement of angles, levelling and measurement of distances the base. A traverse do the count based on error angle of a polygon and distance results size reference to the terms of geometric polygons measured. Within adjustment required leveling high Count in the process of calculation. Therefore, the required computer technology in the process of doing the calculation so that the result is more precision. With the progress of the current process of computer calculations can be done quickly through programming. Program used as thesis harnesses Program macros with visual basic for application (VBA) programming language in microsoft Excel by using the polygon mesh data

Analisis Spasial Persebaran Toko Mebel Di Kabupaten Jepara Propinsi Jawa Tengah

Kabupaten Jepara merupakan kabupaten yang terkenal dengan sentra industri kerajinan ukir dan mebel kayu yang merupakan salah satu komoditi andalan Jawa Tengah. Adanya andalan industri mebel ini menyebabkan sebagian besar lahan di Kabupaten Jepara dimanfaatkan untuk pengembangan industri mebel kayu. Perkembangan industri mebel mempengaruhi pertumbuhan toko mebel kayu di setiap lokasi strategis di Kabupaten Jepara. Tujuan dari penelitian ini adalah untuk mengetahui pola persebaran toko mebel kayu di sepanjang jalan utama di Kabupaten Jepara menggunakan analisis spasial dengan buffering ArcGIS dan mengetahui besarnya pengaruh lokasi (place) terhadap status operasional (buka/tutup) toko mebel kayu menggunakan analisis regresi logistik biner dari SPSS dan OpenStat. Dalam penelitian ini, parameter lokasi yang ditetapkan adalah kedekatan dengan pusat kota dan persebaran pemukiman. Metode yang digunakan dalam penelitian ini adalah metode survei analitik dengan pendekatan cross sectional. Pengumpulan data dilakukan dengan cara pengukuran langsung menggunakan alat GPS Handheld di lapangan. Hasil analisis spasial menunjukkan bahwa jumlah toko mebel di sepanjang jalan utama Kabupaten Jepara pada tahun 2011 adalah sebanyak 377 buah toko dengan pola persebaran toko mebel yang mengumpul di kawasan dekat pusat kota. Nilai persentase toko mebel yang masih beroperasi (buka) adalah sebesar 88,59% dan toko mebel yang sudah tidak beroperasi (tutup) adalah sebesar 11,41 %. Sedangkan hasil analisis regresi logistik biner menunjukkan bahwa nilai persentase pengaruh bersama dari faktor kedekatan dengan pusat kota dan persebaran pemukiman terhadap status operasional toko mebel adalah sebesar 34,21 %. Dari uji statistik tersebut, didapatkan pula kesimpulan bahwa faktor kedekatan toko mebel dengan pusat kota memiliki pengaruh terhadap status operasional toko mebel. Sedangkan faktor kedekatan toko mebel dengan kawasan pemukiman tidak berpengaruh terhadap status operasional toko mebel
