Sodium titanates were synthesized by hydrothermal method using Ti(O2)O.2H2O as the starting material in 10 M NaOH at 150°C for 72 h. Hydrogen titanate nanoribbons were obtained by ion exchange of H+ for K+ in sodium titanates by 0.1 M HCl. TiO2 (B), anatase, and anatase-rutile mixture were obtained by the calcinations of hydrogen titanate nanoribbons for 2 h at 500, 700, and 900°c respectively. Hydrogen titanate nanoribbons were characterized by X-rays Diffraction (XRD), High Resolution Scanning Electron Microscopy (HRSEM) and High Resolution Transmition Electron Microscopy (HRTEM). Microstructure of pseudo-TiO2 (B), anatase, and rutile prepared by the calcinations of hydrogen titanates have been determinated in ab initio by the Two Stage Method from powder XRD data. Hydrogen titanates nanoribbons convert into pseudo-TiO2(B) then anatase and finaly rutile structures by heat treatment. Keywords: polymorphic transformation, microstructure characterization, titanium dioxide

Titanium dioksida (TiO2)merupakan semikonduktor yang memiliki fungsi sebagai fotokatalis, sel surya, anti bakteri, anti polutan, dan anti buram. Salah satu cara untuk meningkatkan aktifitas fungsional TiO2dengan menggeser daerah aktifitas atau energi celah pita (Eg) dari sinar ultra violet (UV) ke daerah sinar tampak melalui penambahan zat pensensitif TiO2.Pada penelitian ini, perak klorida (AgCl) digunakan sebagai zat pensensitif TiO2. Tujuan penelitian ini untuk mengetahui pengaruh variasi perbandingan mol awal [Ti8O12(H2O)24]8.Cl8.HCl.7H2O dengan AgNO3 terhadap sifat-sifat fisik TiO2 tersensitifkan AgCl (TiO2@AgCl) yang disintesis dengan metode pengendapan basah dalam suasana asam. Variasi perbandingan awal yang digunakan yaitu perbandingan mol [Ti8O12(H2O)24]8.Cl8.HCl.7H2O :mol AgNO3sebesar 1:9, 1:10, 1:11, 1:12, dan 1:13yang dilarutkan dalam pelarut etanol (total pelarut 37.5 mL). Sampel padat TiO2@AgCl dihasilkan dengan metode pengendapan basah dalam kondisi asam melalui pengontrolan asam HNO3 pada pH~1. Sampel dihasilkan dari penguapan filtrat yang bebas dari endapan AgCl, hingga volume yang didapat setengah dari volume awal. Sampel TiO2@AgCl dikarakterisasi dengan berbagai instrumen: Difraktometer Sinar-X (XRD),Scanning Electron Microscopy-Electron Dispersive X-Ray Analyzer (SEM-EDAX), dan Spektrofotometer UV-Vis Diffuse Reflectance. Hasil penelitian menunjukkan semua sampel TiO2@AgCl berisi 1 fasa nanopartikel (nanokristalit) TiO2 dan 3 fasa kristal yaitu rutil, anatas, dan AgCl.TiO2@AgCl memiliki bentuk morfologi berupa mikrosferik dengan ukuran berkisar 0.5-1 μm. Berdasarkan hasil analisisdengan spektrofotometer UV-Vis Diffuse Reflectance menunjukkan semua sampel TiO2@AgCl mengabsorbsi sinar ultra violet (UV) dengan Eg sebesar 2.87-3.89 eV, dan sinar tampak dengan Eg sebesar 1.60-2.40 eV. Titanium dioxide (TiO2) is a semiconductor that can be applied in the field of photocatalyst, solar cell, anti-bacterial, anti-pollutants, and anti-fogging. The functional activity of TiO2 can be increased by shifting the activity area from ultraviolet (UV) to visible through the addition of sensitizer. In this research, silver chloride (AgCl) was used as a sensitizer The objective of the research is to study the effect of the initial mole comparison of [Ti8O12(H2O)24]8.Cl8.HCl.7H2O and AgNO3on the physical properties of AgCl-sensitized TiO2(TiO2@AgCl). All TiO2@AgCl were synthesized using the wet chemical precipitation method under acidic conditions by the addition of a concentrated HNO3 with pH ~ 1. The initial comparison variation used was the mole ratio of [Ti8O12(H2O)24]8.Cl8.HCl.7H2O : AgNO3 of 1: 9, 1:10, 1:11, 1:12, and 1:13. Each of these materials was dissolved in ethanol to 37.5 ml. All samples were produced from evaporation of filtrate free from AgCl precipitate, until the volume obtained half of the initial volume. The solid samples were characterized using X-Ray Diffractometer (XRD), Scanning Electron Microscopy-Electron Dispersive X-Ray Analyzer (SEM-EDAX), and UV-Vis spectrophotometer Diffuse Reflectance.The results showed that all samples of TiO2@AgCl consisted of 1 phase of TiO2-nanoparticles and 3 phases of rutile, anatase and AgCl crystals. The morphology of TiO2@AgCl is microspheric with a size ranging from 0.5-1 μm. Based on the results of the analysis with the UV-Vis spectrophotometer Diffuse Reflectance showed that all samples of TiO2@AgCl absorb ultraviolet (UV) rays with bandgap (Eg) ranging from 2.87 to 3.89 eV, and the visible light with Eg ranges from 1.60 to 2.40 eV.

A status report with preliminary results for the IndoBioSys project is presented and the impact of the project results for our knowledge of the Indonesian fauna is discussed. Using the REST API available on the Barcode of Life Data System we recover 21,153 public records (3,390 BINs) from Indonesia and compare against the 21,813 records (3,580 BINs) generated by the IndoBioSys project. From all IndoBioSys BINs, 3,366 (94%) are new to Indonesia. IndoBioSys is responsible for a BIN increase of 36.5% in Lepidoptera, 62.6% in Trichoptera, 986% in Coleoptera, and 1,086% in Hymenoptera. After two years of the IndoBioSys project, the Museum Zoologicum Bogoriense became the depository institution of 51.9% of Lepidoptera records, 95.8% of Coleoptera records, 97.6% of Hymenoptera records and 59.4% of Trichoptera records for Indonesia available on Barcode of Life Data System (BOLD). Now, with 55% of all Indonesian records available on BOLD, it is the most important depository for records of Indonesian genetic biodiversity, housing more than 23,000 new voucher specimens in their collections. Before IndoBioSys, the Museum Zoologicum Bogoriense was responsible for only 9% of all records available in the Barcode of Life Data System for Indonesia, showing the importance of those pipelines in empowering the local institutions in becoming the reference depository of the local fauna.

Kajian awal ngengat berukuran besar telah dilakukan di desa Kwerba, Kaki Pegunungan Foja, Membramo Raya tanggal 1 sd. 29 November 2008 (10 malam). Tujuan dari kajian ini adalah untuk mengumpulkan informasi tentang keragaman ngengat dan juga untuk mengetahui komposisi jenis ngengat di kawasan ini. Hasil penelitian menunjukan bahwa dalam waktu yang singkat hanya diperoleh sekitar 83% dari total yang ada atau sekitar 178 dari total perkiraan 214 jenis. Indeks diversitas Fisher’s ? relatif rendah yaitu 83,17. Demikian juga jumlah famili yang ditemukan di kawasan ini juga rendah hanya 19 famili atau sekitar 1/3 dari total famili yang ada di Indo-Malaya. Secara umum, Pyralidae, Geometridae, dan Noctuidae mendominasi kawasan tersebut. Rendahnya diversitas di kawasan ini berhubungan dengan jenis tanaman yang ada. Pembukaan lahan dan pembalakan liar telah menyebabkan turunnya jumlah jenis pohon tetapi di sisi yang lain kerapatan tumbuhan muda dan jumlah tumbuhhan merambat meningkat. Hanya terdapat sekitar 300 species tumbuhan dikawasan ini. Tentu saja kalau menuju ketinggian yang lebih tinggi dari kawasan kaki gunung ini kemungkinan jenisnya tumbuhan akan lebih banyak karena lebih jauh dari jangkauan penduduk. Sehingga diversitas ngengat di kawasan ini belum dapat digunakan untuk menyimpulkan keragaman ngengat di Pegunungan Foja. Kajian yang lebih intensif yang meliputi seluruh lokasi pegunungan dari dataran rendah sampai puncak masih perlu dilakukan.

Mesoporous pure TiO2 (M-TiO2) and mesoporous-vanadium-doped TiO2 (M-V-doped TiO2) were successfully synthesized via a facile and simple reflux technique. The purpose of this research was to study the effect of vanadium dopant on the physicochemical properties of all materials obtained. Characterization of the prepared materials was carried out using X-ray diffraction (XRD), scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDS) and N2-adsorption-desorption analysis. The presence of Ti and O elements in M-TiO2 and of Ti, V and O elements in M-V doped TiO2 could be detected by SEM-EDS, while the patterns of X-ray diffraction of all the prepared samples had a well-crystalline surface of anatase type. All mesoporous vanadium-doped TiO2 (M-V-doped TiO2) materials performed in a highly transparent mode in the visible region at 554 nm (Eg = 2.24 eV) and 588 nm (Eg = 2.12 eV) for 3.3 and 4.9 wt% V doped TiO2, respectively. The Rietveld refinement method was applied to extract the structural parameters of the M-TiO2 and M-V-doped TiO2 using the Fullprof program in the WinPlotr package. The prepared materials were refined in the crystal system and space group of anatase (tetragonal, I41/amd (141)). The vanadium ion was successfully doped into TiO2. The isotherm type of M-TiO2 and 2.3 wt% V doped TiO2 were of type IV, with a profile of type H2 hysteresis loops, while the 3.3 and 4.9 wt% vanadium-doped TiO2 reflected isotherm type III. The Brunauer-Emmett-Teller (BET) results showed a significant reduction in surface area due to increased concentrations of vanadium. The highest values of BET-specific surface area, pore volume and average pore size of M-TiO2 were 46 m2/g, 18.45 nm and 0.2572 cm3/g respectively.

Effect Of Non-metal Elements (C, N, S) As Anionic Dopants On Electronic Structure Of Tio2-Anatase By Density-Functional Theory Approach Hari Sutrisno
Molekul Vol 11, No 1 (2016)
Publisher : Universitas Jenderal Soedirman

This article is a theoritical approach to calculate the electronic structure of undoped- and non-metal anions doped-TiO2-anatase. The objective of the research is to calculate abinitio the band structure and the density of states (DOS) of undoped-, C-, N-, and S-doped TiO2-anatase. Kohn-Sham equations are performed with the density functional theory (DFT) using the local density approximation (LDA) for exchange-correlation functional. The first-principle calculations were done using supercell (2x2x1) methods as implemented within Amsterdam Density Functional (ADF)-BAND version 2014.10. The ab-initio calculation of the band structures show that all samples are direct- and indirect-gap type semiconductor. The band gap of TiO2-anatase with DFT using LDA is 2.43 eV. The addition of C atom at 0.943% in 48 atoms produces width intermediate band about 0.76 eV, which is 0.38 eV above the valence band (VB) and 1.38 eV below the conduction band (CB). The addition of N atom at 1.103% and S atom at 2.478% in the lattice structure of TiO2-anatase resulted in the addition of the VB width to 0.47 eV and 0.11 eV, while the resulting gap between the VB and the CB to 1.97 eV and 2.33 eV, respectively.

Energi celah pita dan density of state (DOS) dari NaY(1-x)LaxTiO4 (x = 0; 0,25; 0,50 dan 0,75) dapat diprediksi secara teoritis menggunakan pendekatan density functional theory (DFT). Perhitungan awal berdasarkan atas pendekatan local density approximation (LDA) dan generalized gradient approximation dari Perdew-Burke-Ernzerhof (GGA+PBE) sebagai fungsional tukar-korelasi. Perhitungan awal energi celah pita dan DOS dilakukan pada unit sel konvensional (1×1×1) untuk NaYTiO4 dan supersel (2×2×1) untuk NaY(1-x)LaxTiO4 (x = 0,25; 0,50 dan 0,75) dengan program CASTEP Materials Studio. Hasil perhitungan menunjukkan energi celah pita (Eg) sebesar 3,447; 3,384; 3,356 dan 3,560 eV untuk x = 0; 0,25; 0,50 dan 0,75 dengan metode LDA. Di sisi lain, metode GGA+PBE menunjukkan Eg sebesar 3,039; 2,963 dan 2,930 eV untuk x = 0; 0,25; 0,50 dan 0,75. Hasil perhitungan karakter DOS menunjukkan bahwa seluruh material menunjukkan transisi Eg tersebut dikontribusi oleh transisi elektron antara pita valensi O 2p dan konduksi Ti 3d. Susbtitusi atom La pada posisi atom Y tidak menghasilkan pita di tengah Eg (intermediate band) melainkan hanya memperlebar atau mempersempit celah pita pada NaY(1-x)LaxTiO4 akibat distorsi panjang ikatan Ti‒O. Penelitian ini menunjukkan peran signifikan dari La terhadap sifat elektronik material NaY(1-x)LaxTiO4 untuk aplikasi pada sel surya di masa depan. Modification of Electronic Properties of NaYTiO4 Perovskite Material by Variation of Lanthanum Dopants Concentration using Density Functional Theory Method. Bandgap energy and density of state (DOS) of NaY(1-x)LaxTiO4 (x = 0; 0.25; 0.50 and 0.75) can be predicted theoretically using density functional theory (DFT) approach. The initial calculation is based on the local density approximation (LDA) and generalized gradient approximation of Perdew-Burke-Ernzerhof (GGA+PBE) as exchange-correlation functional. Initial calculations of bandgap energy and DOS were performed on conventional unit cells (1×1×1) for NaYTiO4 and supercells (2×2×1) for NaY(1-x)LaxTiO4 (x = 0.25; 0.50 and 0.75) with the CASTEP Materials Studio program. The calculation results show the bandgap energy (Eg) of 3.447; 3.384; 3.356 and 3.560 eV for x = 0; 0.25; 0.50 and 0.75 with the LDA method. On the other hand, the GGA+PBE method shows an Eg of 3.039; 2.963 and 2.930 eV for x = 0; 0.25; 0.50 and 0.75. DOS character calculation results show that all materials exhibit the Eg transition, which is contributed by the electron transition between the O 2p valence band and Ti 3d conduction band. The substitution of La atoms at the Y atomic position does not produce a band in the middle of Eg (intermediate band) but only widens or narrows the bandgap in NaY(1-x)LaxTiO4 due to distortion of the Ti‒O bond length. This study demonstrates the significant role of La on the electronic properties of NaY(1-x)LaxTiO4 materials for future solar cell applications.
