The simulation of Bay of Bengal (included Andaman Sea) has been done. This investigation used equation of motion (Navier-Stokes equation). The equation of motion was solved by means of Hamburg Shelf Ocean Model (HAMSOM). The analysis is done for the…
Simulasi penguraian pati di dalam daun tembakau dilakukan dengan mengembangkan model matematika penguraian pati (di dalam daun) sebagai fungsi dari kondisi pengeringan seperti temperatur, kadar air, waktu, dan konsentrasi awal pati. Model penguraian…
This paper presents the results obtained from the application of computational fluid dynamics (CFD) to modelling the crosswind and steam addition effect on a turbulent non-premixed flame. A pre-processor software GAMBIT was employed to set up the…
Raindrop motion is affected by several factors; one of which is wind speed during the rain. This study is aimed to investigate that impact by using mathematical simulation with Fortran and Matlab. Raindrops arrive on the Earth’s surface at their…
Penelitian ini dilakukan untuk mengamati sinkronisasi estrus dan menentukan diagnosis kebuntingan dini pada domba garut (n=3) menggunakan ultrasonografi transrektal. Domba disinkronisasi dengan menggunakan PGF pada fase luteal. Onset dan durasi…
Peningkatan sifat mekanik karet alam dengan penambahan tanah liat nanokomposit pada kosentrasi berbeda yaitu 1, 3 dan 5 % berat sudah berhasil diteliti. Pada percobaan ini pengujian dilakukan dengan X-Ray Difraction (X-RD) untuk analisa morphologi…
Asymmetric ultrafiltration (UF) membranes were prepared from three kinds of polymer namely polyacrilonitryle (PAN), polysufone (PS), and cellulose acetate (CA) by phase inversion method. Water was used as non-solvent. These membranes were…
Polyurethane (PU) membranes was prepared by reacting the free fatty acids and fatty acids that have been oxidazed from castor oil with a 2,4-toluen di-isocyanate (TDI). He effect of of monomer composition, temperature, and polymerization time was…
This research studied the synthesis of Polyurethane (PU) Membrane from Carrageenan and 2,4 toylulene diisocyanante (TDI). The PU membrane made from the Gracilaria sp of red seaweed has rendement of 60.5% from the total weight of the dried sea grass.…
Palm fly ash is biomass/waste in the palm oil industry. Palm fly ash has high content of amorphous silica. ZSM-5 is one of synthetic zeolite which is widely used as catalyst in industries. ZSM-5 has high activity and selectivity to several…
