    Moslems all over the world should be able to make maximum use of united Islamic calendar as the follow up of the International Hijri Calendar Unity Congress in Istanbul on May 2016 in order to unite time management system of the Muslims. Rigid attitudes which reject hisab and only approved rukyatul hilal have made Muslims keep using Gregorian calendar for 1200 years as the basis of their business accounting. Consequently, Muslims seem to be trapped in zakat debts that keep getting more and more reaching US$ 10 bn. This will immediately become civilization debt and burden of the upcoming Muslim generation if it is not immediately solved

    Pemberian Whole Cell Vaccine dan Lipopolisakarida untuk Meningkatkan Titer Antibodi Dan Tingkat Kelangsungan Hidup Ikan Kerapu Macan (Epinephelus fuscoguttatus) Terhadap Vibrio alginolyticus

    Hean kerapu macan (Epinephelus fascogultaJus) merupakan salah satu jenis ikan taut yang memiliki nilai ekonomis yang tinggi. Kendala yang sering dihadapi pada usaha budidaya ikan kerapu macan adalah munculnya penyakit. Penyakit yang sering menyerang ikan kerapu macan adalah penyakit vibriosis yang disebabkan oleh bakteri Vibrio olginolyticus. Penyakit yang disebabkan Vibrio olginolyticus dapat meningkatkan mortalitas ikan kerapu macan mencapai 80 - 90 %. Penanggulangan penyakit vibriosis dapat dilakukan dengan cara vaksinasi. V aksinasi merupakan cara yang tepat untuk merangsang pembentukan antibodi. Whole cell vaccine (WCV) dan lipopolisakarida (LPS) diharapkan mampu merangsang pembentukan antibodi sehingga tingkat kelangsungan hidup atau survival rate (SR) ikan kerapu macan meningkat. Penelitian ini dilakukan untuk menjawab permasalahan (I) Apakah pemberian WCV dapat meningkatkan titer antibodi dan tingkat kelangsungan hidup ikan kerapu macan yang diinfeksi Vibrio olginolyticus. (2) Apakah pemberian LPS dapat meningkatkan titer antibodi dan tingkat kelangsungan hidup ikan kerapu macan yang diinfeksi Vibrio olginolyticus. Penelitian ini bertujuan untuk mengetahui titer antibodi dan tingkat kelangsungan hidup ikan kerapu macan setelah divaksin dengan WCV dan LPS terhadap infeksi Vibrio alginolyticus. Penelitian ini merupakan penelitian deskriptif. Parameter yang diamati adalah titer antibodi dan SR ikan kerapu macan terhadap Vibrio alginolyticus. Hasil penelitian menunjukkan titer antibodi dan SR ikan kerapu macan yang divaksin mengalami peningkatan dibandingkan dengan kontrol. Perlakuan dengan WCV titer antibodinya meningkat dari 32 menjadi 512. Perlakuan dengan LPS titer antibodinya meningkat dari 32 menjadi 256. SR ikan kerapu macan meningkat setelah diuji tantang dengan Vibrio olginolyticus. Perlakuan denga

    This study aims to determine the level of production, business activities and development efforts knowing that management system Hariah mothers, to increase production of shrimp crackers in the district rebon Hariah Rasau jaya stronghold district highway. The method used in this study is a qualitative approach. Qualitative research is descriptive research studies and tend to use inductive analysis approach. Samples were Hariah mother. Results of data analysis showed that the potential for industrial development in the prawn crackers Rasau jaya big enough because the raw materials are generally not hard to come by, the market opportunity is still very open Technically industrial prawn crackers are produced rebon hariah mothers still prefer the simple and human labor and industry is not generate hazardous waste

    Coherent Acoustic Perturbation of Second-Harmonic-Generation in NiO

    We investigate the structural and magnetic origins of the unusual ultrafast second-harmonicgeneration (SHG) response of femtosecond-laser-excited nickel oxide (NiO) previously attributed to oscillatory reorientation dynamics of the magnetic structure induced by d-d excitations. Using time-resolved x-ray diffraction from the (3/2 3/2 3/2) magnetic planes, we show that changes in the magnitude of the magnetic structure factor following ultrafast optical excitation are limited to Δ/\Delta/ = 1.5% in the first 30 ps. An extended investigation of the ultrafast SHG response reveals a strong dependence on wavelength as well as characteristic echoes, both of which give evidence for an acoustic origin of the dynamics. We therefore propose an alternative mechanism for the SHG response based on perturbations of the nonlinear susceptibility via optically induced strain in a spatially confined medium. In this model, the two observed oscillation periods can be understood as the times required for an acoustic strain wave to traverse one coherence length of the SHG process in either the collinear or anti-collinear geometries.Comment: 26 pages, 7 figure

    A prototype of homemade furnace was built and the highest temperature it can reach during the trial process is approximately 400OC. Beside liquid metal, the furnace also produced exhaust gas as a side product. The exhaust gas is still hot. Hot gas can be used to improve the furnace's temperature based on blast furnace method. To apply this method, the furnace should be companied with cowper. In designing cowper, several parameters should be notice. The parameters are hot gas temperature, air flow direction, and its movement ability with the furnace. Hot gas temperature will determine the number of heat absorber layers. The direction of the air flow will determine the cowper construction. Movement ability is associated with space. The design is made based on VDI 2221. The cowper design concept is cowper to store hot gas made of ramming refectories with its outer diameter similar to oil tank and the movement mechanism only applied for migration
