Pengukuran Tingkat Kesiapan Kantor Pemerintahan Desa Dalam Penerapan Masterplan Teknologi Informasi Dan Komunikasi (Tik) Perkantoran Desa Menggunakan Kerangka Kerja Cobit 4.1
Desa sebagai bagian terkecil dari sistem pemerintahan administratif di Indonesia,dituntut untuk dapat mengikuti perkembangan teknologi dan terus meningkatkan kemampuannya didalam mengelola data administrasi kependudukan desa sebagaimana yang terkandung dalam amanat Inpres No. 3 tahun 2003. Saat ini desa-desa yang berada di Kalimantan selatan, didalam sistem pelayanan administrasi kependudukan desa masih banyak yang bersifat konvensional. Hal tersebut berimbas kepada perangkat desa maupun penduduk desa, dimana sering terjadi human error, serta pemborosan waktu dan biaya. Oleh karena itu dibutuhkan suatu sistem yang mengarah ke e-Government untuk mengatasi permasalahan-permasalahan yang ada. Dalam menerapkan e-Government dan tata kelola TIK di pedesaan diperlukan suatu perencanaan yang matang dan menyeluruh sehingga penerapan TIK bisa berjalan sesuai dengan fungsinya dan dapat membantu menyelesaikan permasalahan yang muncul pada saat telah diimplementasikan. Penyusunan Master Plan TIK untuk kantor pemerintahan desa diharapkan dapat menjadi pedoman atau acuan pemerintah kota dalam menentukan kebijakan, rencana strategis, program kerja TIK, pengembangan unit pengelola TIK, manajemen pengguna, pengembangan infrastruktur jaringan, Infrastruktur TIK, Panduan pengelolaan Sistem informasi, sehingga kantor pemerintahan desa dapat memberikan layanan public yang cepat, tepat sasaran dan melaksanakan visi pemerintahUntuk mengetahui kondisi terkini kesiapan desa dalam penerapan Master Plan TIK pada kantor pemerintahan desa maka perlu dilakukan pengambilan data dengan metode wawancara, analisis data, observasi dan kuisioner yang disusun berdasarkan kerangka kerja COBIT 4.1 domain proses TI PO1 (pendefinisian rencana strategis TI), PO2 (menentukan arsitektur informasi) dan PO4 (pendefinisian proses TI, organisasi TI dan hubungannya)Hasil perhitungan berdasarkan acuan domain PO 1 kerangka kerja COBIT tentang pendefinisian rencana strategis TI berada pada nilai/level kematangan 0.88, domain PO 2 tentang menentukan arsitektur informasi berada pada nilai/ level kematangan 0.66, dan domain PO4 tentang proses TI, organisasi TI dan hubungannya berada pada nilai/ level kematangan 0,85. Dari ketiga domain proses TI tersebut tingkat kesiapan dari kantor pemerintahan desa bisa dikatagorikan pada level 1 (initial/Ad Hoc
Influence of erbium oxide on structural, physical, elastic and luminescence properties of rice husk biosilicate zinc borotellurite glasses for laser application
Nowadays, active search for more efficient and improved glass material to be employed as laser host has been
take place in order to have laser with enhanced performance. In this research, erbium oxide doped rice husk
biosilicate zinc borotellurite glasses have been fabricated successfully via conventional melt quenching technique. XRD pattern reveals that the prepared glasses are amorphous in nature while FTIR spectra records the
presence of Si-O-Si, TeO3, BO4 as well as BO3 vibrational groups in the fabricated glasses. Increasing density from
3.3505 g/cm3 to 4.1852 g/cm3 along with the rigidity of the glass as hinted in the values for elastic moduli from
55.0 GPa to 250.0 GPa is caused by the incorporation of erbium oxide that reduce the amount of non-bridging
oxygen in the glass matrix. Three bands that are recorded in PL spectra correspond to the violet, blue and green
emission
Comprehensive study on the nonlinear optical properties of lanthanum nanoparticles and lanthanum oxide doped zinc borotellurite glasses
Recently, the rapid growth in photonic field has increased the demand for nonlinear materials with higher
performance and greater efficiency. Hence, a thorough investigation on the nonlinear optical properties of
materials are essential and need to be done for possible future application of the material in photonic field as
optical limiting or optical switching devices. Thus, through this research, the crucial parameters in nonlinear
optical properties of zinc borotellurite glasses doped with lanthanum oxide and lanthanum nanoparticles were
studied and investigated extensively. The two series of glasses were successfully fabricated via conventional
melt-quenching technique. The fabricated samples were characterized by using Fourier Transform Infra-Red
(FTIR) spectroscopy as well as Z-scan technique in order to study the structural and nonlinear optical properties
of the glass systems. The existence of various amount of TeO4, TeO3, BO4 and BO3 in all the prepared glasses are
proven through the observable absorption bands in the FTIR spectra. Inconsistent trends recorded for both
nonlinear absorption coefficient and nonlinear refractive index might be associated with the simultaneous
creation of bridging as well as nonbridging oxygen which eventually affect the values for both parameters. The
figure of merit of the prepared glasses with values ranging from 0.055 to 0.267 which are smaller than one hints
that the glass materials possess potential to be employed as all optical devices. 0.03 M fraction of lanthanum
nanoparticles doped zinc borotellurite with FOM value larger than 1 has proven the ability of the respective glass
to be employed as efficient all optical switching devices. The determined nonlinear optical parameters of the
glasses should be able to provide sufficient and useful information on the fabricated glass samples for future
application in photonic field
Structural and optical properties of samarium doped silica borotellurite glasses for optical switching application
The quaternary 56TeO2-24B2O3-(20-x)SiO2-xSm2O3 (x = 0.01, 0.02, 0.03, 0.04 and 0.05 M fraction) glasses were
fabricated by using melt quenching method. XRD analysis reveals the amorphous nature of the prepared glass
samples. FTIR and deconvolution studies show that Sm2O3 influences the modification of the glass network in the
silica borotellurite glass system. The optical band gap and Urbach energy increases and decreases respectively
with the addition of Sm2O3 beyond 0.02 M fraction. The overall refractive index of the glass system decreases
along with the decrement in polarizability and optical basicity. The synthesized glass samples possess metallization criterion values of 0.30399 to 0.31068 which indicates that the glasses can be used for non-linear applications. The nonlinear behaviour of the fabricated samples which include the nonlinear absorption coefficient,
nonlinear refractive index, and third order susceptibility attributed to changes in the glass structure. Silica
borotellurite glass doped with 0.05 M fraction of samarium ox
Physical, structural and optical properties of bio-silica borotellurite glass system doped with samarium oxide nanoparticles
Glasses with chemical composition {[(TeO₂)0.7 (B₂O₃)0.3]0.8 [SiO₂]0.2}1-x {Sm₂O₃ NPs}x where x = 0.01 to 0.05
molar fraction have been fabricated using conventional melt-quenching method. Fourier transform infrared
(FTIR) spectra reveal the presence of TeO3, SiO2 and BO3 structural units in the glass network. The existence of
samarium oxide nanoparticles was recorded through high resolution transmission electron microscopy (HRTEM) with particle size of 71.74 nm. Meanwhile, the optical properties of fabricated samples were determined by
UV–vis analysis. The variation in the optical band gap identifies the modification in the glass network to the
formation of bridging oxygen (BO) and non-bridging oxygen (NBO). Other optical parameter including refractive
index, Urbach energy, electronic polarizability, oxide ion polarizability and optical basicity were determined.
The metallization criterion values obtained is in the range of 0.403 to 0.409, which suggest that the glass
material has a huge potential applications, in non-linear optics fields
