THE INFLUENCE OF FAMILY, PEERS, TEACHING METHODS OF TEACHER, AND THE USE OF INTERNET ON STUDENT’S INTEREST IN LEARNING ELECTRONIC FOR AUDIO VIDEO STUDENTS AT SMK N 3 YOGYAKARTA

This study aim to know about 1) the influence of family, peers, teaching methods of teacher, and the use of Internet on student’s interest in learning electronic for audio video students at SMK N 3 Yogyakarta, 2) from family, peers, teaching methods of teacher, and the use of internet, which is the most influential factor on student's interest in learning electronics for audio video students at SMK N 3 Yogyakarta. The subjects are 99 students of competency skills audio video at SMK N 3 Yogyakarta. The variables are the family environment (X1), the peer environment (X2), the teaching method of teachers (X3), the use of internet (X4), and student’s interest in learning electronics (Y).The Techniques of data collection use questionnaire and the analysis method use 4 Predictors of Multiple Regression. The results show that the family, peers, teaching methods of teacher, and the use of internet have a positive and significant impact on students' interest in learning electronics for audio video students at SMK N 3 Yogyakarta, it can be seen from Rhitung (0.616) > Rtabel (0.195). The relative contribution of each variable is the use of Internet at 66.3%, family environment at 12.27%, teaching methods of teachers at 11%, and 10.5% of peer environment. Thus, the factors that most influential on the student's interest in learning electronics for audio video students at SMK N 3 Yogyakarta is the use of Internet. Keywords: family, peers, teaching methods, internet, interests in learning electronics

Working group written presentation: Trapped radiation effects

The results of the Trapped Radiation Effects Panel for the Space Environmental Effects on Materials Workshop are presented. The needs of the space community for new data regarding effects of the space environment on materials, including electronics are listed. A series of questions asked of each of the panels at the workshop are addressed. Areas of research which should be pursued to satisfy the requirements for better knowledge of the environment and better understanding of the effects of the energetic charged particle environment on new materials and advanced electronics technology are suggested

Plasma charging testing of communication satellites

A discussion is given of ESD as a radiated electromagnetic environment and compares the ESD environment to a standard EMI test environment. An arc generator used to assess the sensitivity of typical spacecraft electronics is described. The results of radiated susceptibility tests conducted on breadboard circuits and a satellite electrical model of a communication satellite are discussed

Parylene C for hermetic and flexible encapsulation of interconnects and electronic components

Flexible electronics are of a great interest for wearable and implantable medical devices due to their conformality with the body, compared to electronics made on rigid carriers. Packaging of such electronics needs to offer sufficient flexibility and in addition, has to provide good protection for the electronics inside, also in humid and harsh environments, to prevent device failure due to corrosion. Parylene C is a popular polymer due to its interesting diffusion barrier properties. Parylene C coatings are also extremely conformal, hence it offers the possibility to be used as flexibleprotecting encapsulation for electronic components and interconnects. In order to provide sufficient mechanical support for the electronic circuit, a second encapsulation in PDMS will be performed. In our work, we study the barrier properties of Parylene for long time exposure to moisture and biofluids. Since adhesion is a very important parameter to prevent corrosion, this property is studied in detail. Various substrates and various adhesion promotion treatments are evaluated. Furthermore, copper interconnects coated with parylene C are immersed in biofluids at 37 C to study corrosion. Accelerated testing is also performed at 70 C to mimic long time exposure in a harsh, humid environment. Since the Parylene barrier layers are typically 5-15 micron thick, they are highly flexible, and hence they are interesting barriers to be used in flexible/stretchable electronics. Therefore, special attention is given to the evaluation of barrier properties when Parylene is bended and stretched

Radiation effects in spacecraft electronics

Effects on the internal spacecraft electronics due to exposure to the natural and enhanced space radiation environment will be reviewed. The emphasis will be placed on the description of the nature of both the exposure environment and failure mechanisms in semiconductors. Understanding both the system environment and device effects is critical in the use of laboratory simulation environments to obtain the data necessary to design and qualify components for successful application
