Judul: Penggunaan Internet Sebagai Media Komunikasi Dalam Menciptakan Hubungan Akrab
Abstrak: This research is about relationships that occur in communication conducted via the Internet. The study used a descriptive approach with a survey method. The respondents were users of Internet services in internet cafes. This study focused on the relationship between individual factors (ethnicity, language, origin of birth, last education, occupation, income, and gender), communication via the internet, and intimate relationships. Based on the results obtained, the last education, occupation, gender appear to be associated with communications over the Internet. It is seen from the intensity of use of e-mail that is high by the majority of Internet users has been characterized by graduating college, and has worked, and female gender are a bit more is high in frequency of use of social networking. Meanwhile, although based on research results of internet users feel the trust and openness that is low, but Internet users feel the concern and compassion that is high. It is known to quite fit with the so-called false intimacy by Henline (2006).

Abstrak: The big role of Information and Communication Technology (ICT) caused the usage of ICT, especially mobile phone and internet, become a part in human daily life. Thus, it is needed to know about the description of the internet user’s behavior from observation and evaluation. This behaviour described so that the policy and infrastructure for internet access can be arranged based on the user’s condition. Ministry of Communication and Information Technology held a survey to get the data about access and ICT usage in household and personal, and analyzed descriptively using contingency table, chi-square test, and correspondence analysis to obtain the behavior of internet user. The analysis results show that 88% of respondence using the internet and user’s behaviors are different due to the demography. In average, frequency of internet usage is once in a week. This frequency does not different between male and female. The highest frequency comes from the users in DKI region. The results also show that older the users are, the frequency of internet usage will be higher too. Location preference in accessing internet from every region is house, except in Maluku & Papua region. Main location that Maluku & Papua’s users choose is internet cafe. Users in this region are using the internet rarely, so it is more efficient to go to internet cafe. Users in the rural use their phone to access internet, when using the internet they do study and searching about the government organization. Correspondence analysis shows that the most common activity the users do is opening social media sites, especially by the teenagers. Meanwhile the activities that kids do are studying and playing game. Based on the job, users are accessing the internet to do various things that can help them fulfill their needs in their daily life.

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.
