Universitas Airlangga ku

Kita bertemu lagi,


Saya akan berbagi pengalaman menjadi mahasiswa UniversitasAirlangga. Pertama sih Awalnya menjadi mahasiswa rasanya tuh agak grogi, ya apa itu. Tapi lama kelamaan tapi percayalah menjadi mahasiswa universal yaitu tidak pernah mengecewakan. Apalagi yang sudah lulus pasti langsung diterima kerja deh. Sulit sih belajar 4 tahun untuk mendapatkan ijazah  dengan namamudan gelar yang disandingkan. Oleh sebab itu adalah Titi harapkan bisa menjadikan prioritas perkuliahan menjadi prioritas utama dalam menuntut ilmu di Universitas Airlangga ini kalau tidak ada ada dan bisa merasakan apa itu arti perkuliahan Apa arti ilmu sebenarnya dalam kehidupan sehari-hari kehidupan sehari-hari kita membentuk step by step untuk melakukan sebuah proses ataupun mendapatkan sebuah hasil yang maksimal. 

Universitas Airlangga sendiri banyak rujukan dosen-dosen yang terbaik untuk mendapatkan ilmu yang apa yang kita butuhkan di dunia perkuliahan namun beberapa hal yang dalam hal dunia perkuliahan kita bisa diharapkan menjadikan sebuah insan yang mulia beratap adil dan berkeadilan. Universitas Airlangga sendiri memiliki beberapa aspek yang dekat dengan perumahan warga sekitar dan menjadikan turut andil perekonomian di sektor kontrakan, warung, resto, cafe dan beberapa hal yang bisa menjadikan perkembangan ekonomi sekitar Perumahan warga. yah ceritaaku akan membingungkan sih tapi sih bisa turut andil untuk menjadikan sebuah bahan ataupun sebuah rujukan. 


Untuk adik-adik yang akan melanjutkan kuliah di Universitas Airlangga ini mungkin agak lucu sih kuliah itu, tapi setidaknya terasa lucu itu bisa memberikan kesan arti sebuah Arti Kehidupan adik-adik sekalian perkuliahan di Universitas Airlangga ini. Untuk menjadi dewasa itu membutuhkan proses, tapi proses itu membutuhkan sebuah langkah awal kecil untuk menjadikan langkah awal berikut dan berikut berikutnya yang diharapkan ada di sekalian bisa menuntaskan pendidikan atau merampungkan sih pendidikan strata satu Diploma S2 atau S3 di Universitas Airlangga ini. Bapak menteri mengatakan bahwa pendidikan merupakan salah satu untuk merubah kehidupan adalah sebagian penduduk di depan yang lebih baik daripada sebelumnya dikarenakan kehidupan sebelumnya itu tidak ada namanya pendidikan tinggi dan diharapkan ada Adik bisa menempuh pendidikan yang setinggi-tingginya. Mungkin itu cukup sih dari saya selaku penulis. Mungkin banyak salahnya ataupun tulisan saya banyak yang Ngaco assalamualaikum warohmatullohi wabarokatuh

Progress on ligands effects in porphyrin-based molecules in benzene solvent for photodynamic therapy applications
a  Department of Engineering Physics, Institut Teknologi Bandung, Bandung, Indonesia
b  Theoretical Physics Group, Department of Physics, Universitas Airlangga, Surabaya, Indonesia 

Abstract
Density Functional Theory (DFT) calculations are carried out to investigate the ligands effects on porphyrin-based molecule in benzene solvent environment. Benzene solvent is modeled by PCM Tomasi. We are motivated to study the alternation of electronic and geometric structure of porphyrin-based molecule in the presence of ligands for achieving theoretical explanation about ligand porphyrin-based behaviours. We aim to investigate the ligands effect on the groundstate electronic structure of porphyrin-based molecules. This investigation will lead us in better understanding on characteristic of porphyrin-based molecule as photosensitizer in benzene solvent environment. We perform the electronic structure calculation of ZnP, ZnTPP, ZnTBP, H2TPP and H2TBP in the ground state. The results show that ligands distortion induces the point group symmetry of ZnTBP, ZnTPP, H2TBP and H2TPP belong to the trivial point group (C1) in benzene environment. Tetrabenzo ligand distortions significantly change the Zn-N bond of ZnP. The energy difference between HOMO and HOMO-1 is increasing in the present of ligand. We also report that benzene solvent has only significant contribution to the alternation of EΔ of porphyrin-based molecules. © 2013 IEEE.

b  Departement of Physics, Airlangga University, Surabaya, Indonesia 

Abstract
This paper describe a visual feedback control experiment for manipulator robot with camera on its hand using 2.5-D visual servoing control scheme. This scheme does not need estimate full 3D model of target object. Design of image jacobian matrix is separated between translation motion that using image based scheme and rotation motion that using position based scheme. The task of robot was approaching an object with specific desired position and orientation. A 6DOFAdept Viper s850 robot and Logitech C920 web camera are used in this experiment. An experiment architecture adapted to facilities in our lab. © 2013 IEEE.

Preparation optimization and utilization of PVDF membranes for separation of indigo textile dyes

a  Departement of Chemistry, Surabaya State University, Surabaya, Indonesia
b  Departement of Chemistry, Airlangga University, Surabaya, Indonesia 

Abstract
In this study, has been conducted polyvinylidene fluoride (PVDF) membrane preparation process using a phase inversion method with immersion-precipitation technique and its use in the separation of the indigo textile dye. To be able to produce the highest quality PVDF membrane, conducted research on the effect of casting solution and non-solvent composition on the morphology, mechanical strength (young's modulus) , flux and rejection coefficient of PVDF membrane. The results obtained show that, in the composition of the casting solution 16%PVDF/84%NMP/0%NH4Cl and nonsolvent 50%H2O - 100%H2O, has been formed a PVDF membrane with asymmetry structure (a combination of sponge and finger pore) and pore size of 206.1 - 263.9 nm. Meanwhile, the variations in the composition of casting solution (14% PVDF/84%NMP/2%NH4Cl - 16%PVDF/84%NMP/0%NH4Cl) and non-solvent composition (100%H2O/0%C2H5OH - 0%H2O/100%C2H5OH) , produced the PVDF membrane with mechanical strength and flux, respectively in the range of 1237.62 - 5583.44 N/m2 and 1421,868 - 2214,367 L/m2.jam. Furthermore, to determine the selectivity of the PVDF membrane in separation indigo dye, indigo dye (50 ppm) filtration process is carried out on pressure 1 atm and the result is a rejection coefficient values obtained in the range of 82.12 - 95.77%. It shows that the selectivity level of the filtration process is carried out, has been obtained permeate concentrations were in the range 8.94 - 2.12 ppm. Data analysis using Analysis of Variance (ANOVA) showed a significant effect of casting solution and non-solvent composition to mechanical strength, flux and rejection coefficient of PVDF membrane. © Research India Publications.

Ab initio simulation of crystallization of amorphous Ge-Te-In system

b  Departments of Physics, Faculty of Science and Technology, Airlangga University, Surabaya 60115, Indonesia 

Abstract
Phase change materials are promising candidates for memory materials because their ability to change between amorphous to crystalline state or vice versa with the application of specific profile of heat. Due to fast transition between crystalline and amorphous form, chalcogenide based on Ge-Te has been regarded as potential candidate of phase change materials. Our investigation of amorphous structures of GeTe4 with indium dopant have shown that amorphous Ge-Te-In has a significant number of fourfold rings which are responsible for the rapid crystal growth in crystal-amorphous transition. In the present study, ab initio molecular dynamics were used to study crystallization process of GeTe4 with indium dopant (5, 10, 15 and 20 at%). The structural changes in transition process were analyzed by evaluation of ring statistics. Results from ab initio simulations show that crystallization of samples with 80-100 atoms occur in hundreds of picoseconds. © 2013 Bulgarian Academy of Sciences, Union of Chemists in Bulgaria.
