Numerical integration of coupled Korteweg-de Vries System

We introduce a numerical method for general coupled Korteweg-de Vries systems. The scheme is valid for solving Cauchy problems for arbitrary number of equations with arbitrary constant coefficients. The numerical scheme takes its legality by proving its stability and convergence which gives the conditions and the appropriate choice of the grid sizes. The method is applied to Hirota-Satsuma (HS) system and compared with its known explicit solution investigating the influence of initial conditions and grid sizes on accuracy. We also illustrate the method to show the effects of constants with a transition to non-integrable cases.Comment: 11 pages, 13 figure

Hasil penelitianmenunjukan bahwa terdapat hubungan antara pengetahuan, sikap dan tindakan dengan perilaku pemanfaatanalat kontrasepsi pria pada tenaga pendidik dan kependidikan di Universitas Halu Oleo Kota Kendari tahun 2016dengan pengetahuan nilai ρvalue(0,026)< (0,05.), sikap nilai ρvalue(0,014)< (0,05.), dan tindakan nilai ρvalue(0,039)< (0,05.)

Effects of choice feeding a completed feed and corn on the performance of broilers

Poultry feeding systems are likely to change for increased efficiency of production. An experiment was conducted to compare the response of broilers to choice feeding of corn with a standard broiler ration. The treatments consisted of providing broiler feed as the only feed (SINGLE FEED) and access to corn as a choice to a complete broiler feed (CHOICE FEEDING). Weights and feed consumption were obtained at weekly intervals. Samples at the conclusion of the experiment were taken to determine the weight of abdominal fat. Results showed that there was no significant difference in term of liveweight between the two feeding regimes. However, birds given a choice of the broiler feed and corn had better feed efficiency which is reflected by the lower total feed intake. Corn intake was 23.1% of total feed intake in the choice fed birds. In term of carcass colour, birds fed corn as a choice was observed to have a deeper yellow skin colour than the birds fed with broiler feed only

Superconducting YBCO and BSCCO thin films prepared by pulsed laser deposition and post annealing / Jannah A. N. and Halim S. A.

The YBCO and BSCCO superconducting thin films have been grown on MgO (100) by pulsed laser deposition from a sintered YBa2Cu3Oy and Bi1.6Pb0.4Sr2Ca2Cu3Oy target. Post annealing after deposition at 850OC in 30 minutes resulted in BSCCO superconducting films with zero resistance at 52 K. YBCO film annealed for 2 hours is non-superconducting but it is improved by increasing the time to 4 hours and 5 hours at 920OC . X-Ray diffraction pattern shows a predominance of 001 peaks for BSCCO film and no improvement of crystallinity after annealed for YBCO film

Sistem Informasi Pengelolaan Uang Komite Menggunakan Borland Delphi 7 pada SMA Negeri 5 Kota Ternate

Salah satu upaya untuk meningkatkan akuntabilitas, pengendalian internal dan keamanan pengelolaan uang komite dengan mengurangi subyektifitas personal yang melaksanakan pencatatan dan membatasi kesalaan pencatatan. Untuk dapat mengurangi subyektifitas personal dalam pencatatan dan membatasi kesalahan pencatatan dapat dilakukan dengan sistem pencatatan yang terkomputerisasi, SMA Negeri 5 Kota Ternate merupakan salah satu Sekolah Menengah Atas (SMA) yang ada di Maluku Utara khususnya di Kota Ternate, dalam proses pengelolaan uang komite masih manual dan belum terkomputerisasi dimana proses pencatatan pengelolaan uang komite yang dicatat pada buku, buku merupakan media yang mudah rusak sehingga data yang ditulis pada buku tersebut bisa hilang dan terhapus, sehingga di anggap kurang efektif. Penelitian ini dilakukan pada SMA Negeri 5 Kota Ternate, Sistem ini diharapkan dapat mempermudah pegawai untuk melakukan pengelolaan uang komite siswa secara terkomputerisasi serta meningkatkan kualitas pelayanan pada Siswa di SMA Negeri 5 Kota Ternat
