Toward Mobile-Assisted Language Learning (MALL): Reaping Mobile Phone Benefits in Classroom Activities

Mobile phone has been studied by researchers in its connection with education-related activies. This study was aimed at investigating two research questions: 1) what are students' perception toward mobile phone to support classroom activities; 2) How do students experience mobile phone use to support classoom activities? This study employed qualitative method. To collect data, there were some technique used: questionnaire and observation. Students participated in this study were 70 students. Findings showed that student had positive perception and attitude toward mobile phone to support classroom activities. In classroom they used mobile phone to support classroom activitis. Reading E-Book that support subject, playing Audio and Video File, operating offline dictionary were activities supported by mobile phone use

Ab initio density functional investigation of B_24 cluster: Rings, Tubes, Planes, and Cages

We investigate the equilibrium geometries and the systematics of bonding in various isomers of a 24-atom boron cluster using Born-Oppenheimer molecular dynamics within the framework of density functional theory. The isomers studied are the rings, the convex and the quasiplanar structures, the tubes and, the closed structures. A staggered double-ring is found to be the most stable structure amongst the isomers studied. Our calculations reveal that a 24-atom boron cluster does form closed 3-d structures. All isomers show staggered arrangement of nearest neighbor atoms. Such a staggering facilitates $sp^2$ hybridization in boron cluster. A polarization of bonds between the peripheral atoms in the ring and the planar isomers is also seen. Finally, we discuss the fusion of two boron icosahedra. We find that the fusion occurs when the distance between the two icosahedra is less than a critical distance of about 6.5a.u.Comment: 8 pages, 9 figures in jpeg format Editorially approved for publication in Phys.

Evaluasi Area Kawasan Keselamatan Operasi Penerbangan (KKOP) Akibat Perubahan Panjang Runway (Studi Kasus : Bandar Udara Internasional Sultan Syarif Kasim II Pekanbaru)

The objective of the study was to evaluate and to calculate the required the existing 2016 and ultimate 2035 KKOP of Sultan Syarif Kasim II International Airport Pekanbaru. The KKOP area was drawn using ArcGIS Software package, the calculation was carried by using ICAO Manual Standard Annex 14 2013, Ministry Decree Number 60 2004 and Number 3 2016. It is identified that Approach and Take Off Surface in 2016 = 155 meters AES and in 2035 = 152 meters AES, the elevation for inner horizontal surface in 2016 = 50 meters AES and in 2035 = 47 meters AES , the discreapancy for both approach surface elevation of 1,97% to 6,38% for inner horizontal surface. It is also identified that runway length in 2016 = 2.600 meters will be extended to 3.000 meters in 2035, than area of inner horizontal in 2016 = 34.783.800 m2 became in 2035 = 50.300.000 m2, it's not necessary the change of runway length from 2016 to 2035 affected to unincreased in KKOP elevation usualless KKOP distance length

Analisis Perancangan Pompa Guna Pemenuhan Kebutuhan Air Bersih Pdam Kota Amuntai

Air merupakan unsur terpenting bagi kelangsungan hidup di muka bumi. Sebab tanpa air kehidupan di muka bumi ini tidak akan ada. Semua mahluk hidup selalu memerlukan air untuk bisa tumbuh dan berkembang secara wajar. Seiring meningkatnya penduduk kota Amuntai yang mengakibatkan kebutuhan air bersih meningkat pula, sementara sarana air bersih dari PDAM masih terbatas. Berdasarkan alasan-alasan di atas, maka diperlukan suatu analisis perancangan pompa guna pemenuhan pemakaian air bersih yang dapat digunakan untuk menilai kelayakan suatu sistem distribusi untuk penyaluran air bersih. Pompa air yang sesuai untuk masalah ini ialah dengan menggunakan pompa sentrifugal. Pompa sentrifugal ialah jenis pompa dimana headnya dibentuk oleh gaya sentrifugal maupun lift yang ditimbulkan oleh sudu-sudu yang berputar. Dalam penelitian ini, difokuskan pada penelitian tentang pompa sentrifugal yang sesuai kapasitas air yang dibutuhkan untuk sebuah pompa dimana berdasarkan hasil perhitungan untuk setiap kapasitas air yg dipompa yaitu sebesar 422 m3/jam dan bentuk impeller yaitu : diameter dalam (d1 = 0,214 m), diameter luar (d2 = 0,362 m), (β1 = 17o), (α1 = 62o), (β2 = 25o), (α2 = 20o), (ρ = 172,7 mm), (z = 11) dengan spesifikasi pompa yang digunakan sebagai masukan yaitu kecepatan motor penggerak = 1500 (rpm), tebal sudu impeller = 5 (mm) dan tegangan torsi aman bahan shaft (S45C ) = 58 (Kg/mm3). Dari hasil perhitungan dapat disimpulkan bahwa kebutuhan air bersih yang semakin meningkat maka akan dibutuhkan pompa dengan spesifikasi yang lebih tepat pula dan dimensi impeller akan berubah sesuai dengan spesifikasi pompa yang dirancang sehingga kerja pompa lebih optimal untuk memenuhi kebutuhan air bersih pada tahun 2022
