Abstract

The leak of LPG system can not be avoided in its uses as domestic fuel which considering it is one of the result from difussion fl ow. The leak because of difusion fl ow in 3 kg LPG tube is mostly caused by Laminar difussion fl ow known by comparing compressive stress with gasket seating stress which value less than 1 with characteristic in exponensial equations. Augmentation of compresive stress is proved in minimizing diffussion fl ow which cause subtraction in leak until 33.18% for NBR seal and 36.43% for vulcanized seal. Minimizing leak caused by increasing compressive stress is very affected by seal material composed representated by AL and nL. Numerical analysis founded that von mises stress received by seal is still under yield strength from rubber material with Factor of Safety (FOS) achieve at 7.08, this condition affi rms that defl ectation happened in Seal in its elastic area with maximum value about 1.326 mm. Beside that, numerical analysis show that difussion fl ow is occurred in seal creating gradation concetration based on the imminent of diffusion contact.

Abstract

The existence of counselors in Special Capital Region of Jakarta is following the regulation of the Ministry of Religion in carrying out guidance following their duties and functions. The development of globalization is moving very fast both in technology and science. This acceleration is related to the digital era and the state of culture. However, the implementation of guidance carried out by the counselors in Jakarta is still experiencing dynamics, especially in the factor of the dynamics of the counselors. This study uses a phenomenological approach and an interpretive paradigm including the types of data, data sources, primary data sources, and secondary data sources. In this study, the data was analyzed through data reduction, data presentation, and data verification. This study implemented the theory of public spaces. The results of this study indicate that the first factor of the dynamics of religious instructors is internal factors; extension education, understanding of Hinduism, tasks, and challenges of life. Secondly, the external factors; dialectics of communication and the development of information technology, adjustment, and ethical tolerance of extension workers. This is as a self-help extension in life to guide a form of applying devotional values ​​to Hyang Widhi Wasa.
