There has been conducted Physics research on a material, that is, monitoring electric characteristic of a material using four-point probe method. This research measures current and voltage. The result is used to determine resistivity of a material. The research uses 2 samples, that is, chalk and charcoal. The result shows the resistivity of the sample in the form of bulk (t>s) for chalk has high resistivity on voltage of 6.6 Volt. Meanwhile, resistivity on thick sheet (t<s) has high resistivity on voltage of 7 Volt. On the charcoal material, large resistivity (t>s) is in 6 Volt, and on large resistivity (t<s) is in 6.6 Volt.
The era of globalization requires someone to have intelligence in facing all difficulties and challenges, not closing the possibility of physical education learning. In this study, an increase in emotional intelligence was developed using learning models. The research model used was quasi-experiment with the design of the pretest post-test two treatment design. Emotional intelligence plays a role in realizing educational goals, this is expected to increase conducive learning. In learning emotional intelligence is not very popular but is a basis for assessing students 'abilities and for understanding students' feelings. Emotional intelligence is expected to be a determining factor in the bridge to achieve learning outcomes. It is expected that teachers of Physical Education in using Emotional intelligence can use Inquiry learning models.
Mangrove forests have an important function in human life that cannot be replaced by other functions. The existence of mangrove forests has six main functions, namely biological, ecological, physical, social, economic and chemical functions. This article discusses the description of mangrove forest management in meeting the needs of the economic and social functions of the fishing communities on the coast of Merauke Regency, Papua Province, which were reviewed descriptively using relevant literature studies. In terms of economic function, mangrove forests provide economic value for fishing communities because mangrove forests become habitat for crabs, fish and other marine biota that are captured and sold as the main source of family income. In addition, the use of mangrove forests by fishermen on the coast is used as firewood and building materials. The high utilization of mangrove forests by coastal communities that ignores ecological sustainability causes damage to mangrove forests that threatens the sustainability of ecological functions. Damage to mangrove forests in Merauke in the period 2000-2005 was recorded as wide as 2,416 ha while in the 2005-2010 period damage reached 2,233 ha of the total area of the Merauke mangrove forest which reached 216,001.95 Ha or 6.98% of the Merauke forest area. Based on this, the management of mangrove forest utilization needs to get more attention from various parties so that the ecological function of mangrove forests as a condition of sustainable development, especially for fishing communities on the coast, can be realized in Merauke Regency.
The problems of this study: whether there is a relationship between speeds with dribbling skills on the students of physical education department, Universitas Musamus in playing football. The purpose of this study was to determine the relationship between speed and dribbling skills on the students of physical education department. This study was used 102 students as population with a sample of 25 students. This study is a survey method which utilizes test and measurement techniques. Correlation analysis results obtained are r count 0.975>r table 0.396. This research shows that there is a very significant relationship between speed and dribbling skills on the students of physical education department, Universitas Musamus in playing football.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
