Published: April 2020

The problem of fault line selection for the distribution network of neutral point via arc suppression coil grounding has not been solved for a long time. Based on this, a single-phase ground fault line selection method based on dynamic time bending distance similarity is proposed. Firstly, the single-phase ground fault feature analysis of the distribution network of the zero-mode network is used to determine the electrical characteristic quantity of the single-phase ground fault line selection. Then, the faulty electrical feature quantity is improved by the dynamic time bending distance algorithm to form the distance matrix. The similarity data processing is performed on the matrix to obtain a line selection vector, and then the fault line is selected. Finally, the single-phase ground fault system model of 10kV distribution network is constructed by Matlab/Simulink. The correctness and feasibility of single-phase ground fault line selection method based on the dynamic time bending distance similarity is verified by simulation under different fault conditions.

Published: April 2020

Based on the survey data of Jiaozhou Bay in May, August and October 1992, the migration and variation of PHC content in offshore oil spill in Jiaozhou Bay were studied. In August, Station 2106 at the eastern central Point of Jiaozhou Bay was taken as the source of offshore oil spill, and its PHC content was 0.056 mg/L. A series of concentric circles with different gradients formed around there, and there was a descended distribution trend from the center to the periphery along the gradient. The content of PHC decreased from 0.056 mg/L at the center to 0.024 mg/L in the central water, 0.027 mg/L in the northwest water, 0.041 mg/L in the northeast water and 0.048 mg/L in the southeast water. According to the horizontal absolute loss velocity model of material content, it was calculated that the horizontal absolute loss velocity of PHC content in the surface waters from the eastern central water to the central water of eastern Jiaozhou Bay in August was 0.45 Yang Dongfang absolute number, and it decreased to 0.42 in the northwest water, 0.36 in the northeast water, and 0.29 in the southeast water. According to the horizontal relative loss velocity model of material content, it was calculated that the horizontal relative loss velocity of PHC content in the surface waters from the eastern central water to the central water of eastern Jiaozhou Bay in August was 8.03 Yang Dongfang absolute number, and it decreased to 7.50 in the northwest water, 6.42 in the northeast water, and 5.17 in the southeast water. Therefore, with Station 2106 in the eastern central Point of Jiaozhou Bay as the source of offshore oil spill, there was a descended PHC content distribution trend from the center to the periphery with the horizontal absolute loss velocity of 0.29-0.45 Yang Dongfang absolute number and the horizontal relative loss velocity of 5.17-8.03 Yang Dongfang relative number. The rising PHC content distribution was consistent with that of the horizontal absolute (relative) loss velocity of PHC content: that of the central water < that of the northwest water < that of the northeast water <that of the southeast water. PHC content indicates the variation amount from the source to certain water, namely terminal value. The horizontal absolute (relative) loss velocity of PHC content indicates the variation process from the source to certain water, namely process value. This reveals that both the terminal value and the process value of PHC content present the migration process of PHC content in waterbody. According to the horizontal velocity model of Yang Dongfang material content, the decreasing and migration process of PHC content toward the periphery along the gradient can be calculated and quantified.

Authors: Anwar Ali
Published: April 2020

This study discusses kyai’s roles in responding to the social, economic, and political changes in Kediri, East Java, in the post new-order era. Since the collapse of Soeharto’s power in 1998, Indonesia was viewed as a model of the unity of Islam and democration. Islam played important roles in the orientation of the political form in Indonesian. The stronger contribution of the Muslims after the new order can not be separated from the roles of kyai. To date, kyai has a role of selecting outside cultures that enter the society. Unfortunately, the capability of kyai to selesct outside cultures is often not comparable to the swift flow of culture that reduce the role of kyai. This study concludes that the ownership of all symbolic, social, economic, and cultural capitals, has not been able to lead kyai to be successful in all arenas of their struggle.This is because efforts to strengthen economic and social capitals, especially political capital, turned out to weaken symbolic capital. The further impact is that their followers do not provide adequate support when kyai develop their wings in economic and political affairs.

Environmental issues have become global issues that must be addressed by all levels of society in a responsive and focused manner. Since the 1970s, the world community began to pay great attention to the problems of nature and the environment. The discourse on environmentally sound economic development is of particular concern in order to maintain the sustainability of life throughout the world, including the regions in Indonesia. To achieve environmentally sound development is not enough to only enhance economic development and forget about the sustainability of the ecosystem and social environment of the community, both must be mutually integrated until finally a strong national economic development is achieved in order to save the nation's future. This study aims to find out how the implementation of regional economic development in Indonesia has applied the principles of environmental economic development that is environmentally sound as an effort to build and save the future of the nation or just become a slogan on its journey. The type of research used in this study is descriptive using literature studies. The result is known that Indonesia has not been able to carry out the improvement of regional economic development with an environmental perspective. The development carried out in Indonesia since the 1970s still tends to focus on economic development, even on economic growth which tends to be shortterm orientation so that the problem of sustainability development has not become a top priority. For this reason, in the context of aspirational environmentally sound development, the implementation of development must rely on the principle of benefits and sustainability, community, justice, togetherness, openness, and integration.
