Zinc oxide, ZnO, has been attracting much attention because of its potential applications in photonic and optoelectronic devices. The notable properties of ZnO include direct band energy gap (Eg=3.37 eV at RT), large exciton binding energy of 60 meV, and strong cohesive energy of 1.89 eV. Recent reports on the lasing mechanism of ZnO have shown that ZnO is a promising photonic material for exciton devices in the wavelength ranging from blue to ultraviolet. It is well known that high quality materials are required for optoelectronic devices. At the current stage the problems in extending...

Providing a reliable and sustainable power supply
with appropriate environmental considerations to
remote areas, especially in developing countries, is
the main aim of this research. There have been many
natural disasters in Indonesia, primarily the Aceh
Tsunami on Boxing Day 2004, and followed by many
others, such as the earthquake in Yogyakarta in
2006, the Padang earthquake in 2007, and earthquake
in Manokwari, Papua, in early 2009. Some other
disasters in other regions include: the Maldives, a
country formed by a group of natural atolls located
to the southwest of India, which...

This work holds the proceedings of the 4th UPI International Conference on TVET, held on November 15-16, 2016 in Bandung, Indonesia. Regionalization and harmonization in TVET examines research and practices in both national and international contexts. The chapters discuss standardization in TVET regionalization and harmonization, skill and personal development, social and cultural issues, teaching innovations in TVET, and innovations in engineering and education.
