It provides a change in students' learning style to make educators change online-based learning using various platforms, one of which is the Physics Virtual Lab (PVL). This application is in a simulation designed explicitly physics practicum, accessed using a mobile phone. This study aims to determine how effective the use of PVL in fulfilling practicum activities is in terms of perceptions and competencies of students' attitudes. The research method is descriptive research to obtain an overview of PVL applications in physics practicum using domestic used materials. The subjects in this study were students of the first-semester science education study program who took the Basic Physics course-collecting data using perception questionnaires and attitude assessment sheets. The average student perception score is 4.22. Then, the students' attitude competence results obtained an average score of 80.88 integrity; independence 74.89; confidence 75.17 and responsibility 84.89. It shows that the implementation of PVL builds students' integrity and responsibility.

The primary data were collected in July 2018 through a comprehensive survey that sampled respondents representing the whole Indonesian population. The questionnaire was developed by extracting the 4 (four) main issues regarding which the potential users of the IoT technology may have concerns, i.e., willingness to use the IoT services, concerns related to rejection and worries about the IoT, the characteristics of the IoT hardware, and perceptions about the role of the IoT within the existing system. The results of the survey were analyzed to capture the profile of the prospective IoT market, and the strategic implications of the findings were considered. Several interesting results were found, ranging from answering the common question of what kinds of the IoT services are most anticipated to answering the delicate question of how the Indonesian people perceive the disruptive force that the IoT technology may exert. The contribution of this research is that it can be used as an initial guide or reference for regulators, the government and the IoT firms that will begin to deploy services in Indonesia. INDEX TERMS IoT, Internet of Things, Indonesia, developing country, market, technology.

The isolates were placed into vegetative compatibility group (VCG) based on pairing of complementary mutants. From complementation tests, all F. solani isolates did not form heterokaryons and was therefore heterokaryon self-incompatible. For both F.oxysporum and F. proliferatum isolates, four VCG were identified. The results suggest that variation exist among the F. oxysporum and F. proliferatum isolates from root and stem rot of orchid.

(1) The description of students attitudes toward social norm for SMP 07 Satu Atap Pujud. Largely have shown a positive attitude towards social norms and there is a small part that is negative to the social norms. Examples being negative is often grumble to parents when in advise, laughings, as a daughter not dating until late at night, as the girls do not wear tight clothes, for example pencil pants and short shirts.

The level of parental education is the dominant elementary / junior declared the value of the character of social norms whereas, higher education levels maintain coorperation, job dominant parents are farmers de...
