Judul: Faktor-faktor Komunikasi yang Berhubungan dengan Motivasi untuk Meningkatkan Kinerja Organisasi (Studi Kasus di Pusdiklat Pegawai Departemen Komunikasi dan Informatika Jakarta Barat)
Abstrak: This research attempts to answer the questions of communication factors such as characteristics of personality, human relations, communication organizational have correlation with officials motivation to improvement organization activity. This research was done using survey research method and analyzed of software SPSS version 12.00, statistical method namely Chi-Square and Spearman-Rank test to see correlation among variables. The number of the respondent is 85 officials in Pusdiklat Kominfo. Reliability of instrument has realiable with value Rcount 0,774 (human relations), 0,710 (communication organizational) dan 0,895 (motivation) more high than Rcritical 0,247. The result of this research are (1) There is positive significant correlation between characteristics of personality (education, functionary) with motivation (self actualization, expectation) and negative significant correlation between level of position and physiological needs (2)There is significant correlation between human relations with officials motivation (3) There is significant correlation between organization communication and officials motivation.

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
