Mesin pengering kunyit ini menggunakan kompor sebagai media pemanas dengan tabung LPG 3 Kg sebagai bahan bakarnya. Mesin ini menggunakan penampang penahan berupa pelat stainless stell supaya panas yang dihasilkan dari kompor tidak langsung mengenai kunyit, dan untuk loyang di tata secara siksak agar udara panas bisa b…
Perubahan manajemenkimia air pada reaktor PWR (reaktor air bertekanan) telah terjadi, akhir-akhir ini. Manajemen kimia air pada airreaktor memainkan peran sangat penting untuk menjamin integritas bahan bakar, menurunkan degradasi materialdan menurunkan paparan radiasi. Terakhir ini, usaha untuk meningkatkan output day…
Dari sudut pandang sistem energi dan lingkungan, konsep Reaktor Garam Cair (Molten Salt Reactor /MSR) sebagai salah satu jenis reaktor nuklir generasi IV yang mempunyai kemampuan baik untuk alatpembangkit listrik. Dalam MSR, panas dari bahan bakar diserap helium melalui alat penukar kalor. Heliumdigunakan sebagai flui…
Optoelectronic switches based on VO2 thin films are analyzed as input-output devices (I/O) of multiple responses to stimuli of electric tension, temperature and energy of the incident electromagnetic radiation. The representations used are based on their transfer function (TF), in the space state (SS) and in the repre…
The paper proposes a new approach to improve the technological properties of polychloroprene adhesives by changing the mixing regime. This approach has contributed not only to improving the rheological and mechanical properties of the adhesives used, but also for a detailed theoretical explanation of the rheological b…
Paper-based microfluidic sensors are becoming very popular in applications requiring chemical analysis. This thesis deals with preliminary surface chemistry studies which form the foundation for development of cellulosic microfluidic devices. Nanocellulose was chosen as the substrate and alkylsilanes were used to modi…
In this Letter we investigate factors that influence the effective critical electric field for runaway-electron generation in plasmas. We present numerical solutions of the kinetic equation and discuss the implications for the threshold electric field. We show that the effective electric field necessary for significan…
Hidrogen yang akan diproduksi secara termokimia melalui dekomposisi HImenggunakan termal nuklir dari reaktor berpendingin gas temperatur tinggi(HTGR) sebagai pemasok panasnya.Hidrogen hasil produksi dekomposisi HI dipisahkan dari bejana proses dekomposisi dengan menggunakansilinder membran silika(SiO2). Ukuran membran…
This work was carried out of behavior of Al-Zn alloy systems in chloride solutions of different concentrations, with additional alloying indium, gallium and bismuth as micro alloying elements. In addition to these elements is done by the alloying with tin. Thus obtained aluminum alloy with additional corrosion and ele…
Significance: Liu and co-workers report the direct insertion of nitriles into zirconocene-1-aza-1,3-diene complexes for the synthesis of variously substituted N-H and N-substituted pyrroles in high yields.
