Urgensi Dakwah Bil Hikmah pada Generasi Millenial
Authors: Alhidayatillah Nur
Published: September 2020

Generasi millenial yang kerap menggunakan teknologi dan informasi dalam segala aktivitasnya menjadi pusat perhatian saat ini. Generasi millenial dianggap prontal oleh generasi terdahulu karena dianggap merombak tatanan-tananan kehidupan masyarakat yang sudah dianggap baik dan harmonis selama ini. Kemajuan teknologi informasi dan komunikasi yang teradopsi dari kemajuan ilmu pengetahuan dan teknologi mengakibatkan terjadinya pergeseran nilai, baik bersifat positif maupun negatif. Nilai-nilai positif bisa dilihat melalui perpaduan kebudayaan Islam dan kebudayaan Barat yang menjadikan Islam semakin kaya akan nilai-nilai kebudayaan melalui pembuktian sains dan teknologi. Sedangkan dampak negatif lebih kepada peniruan cara hidup yang dianggap tidak sesuai dengan budaya ketimuran. Melihat banyaknya fenomena generasi millenial yang mengkhawatirkan maka diperlukan adanya kontrol sosial. Salah satu control sosial yaitu melalui kegiatan dakwah dengan metode bil hikmah. Kurangnya figur yang bisa dijadikan teladan melatarbelakangi metode ini untuk bisa diterapkan. Pemanfaatan media-media informasi bisa digunakan sebagai sarana dakwah karena generasi millenial kerap menggunakannya.

Published: September 2020

Wind farms are power generation complexes with nonlinear characteristics. It is well-known that such facilities are potential sources of harmonic current injection upon the network. In this sense, in cases where limits established by the regulatory agencies are exceeded, filtering strategies must be provided. Under these circumstances, passive filters are a widely employed solution for bringing harmonic distortion levels to within standard limits. However, it is recognized that the connection of passive filters can influence the characteristics of the system, causing resonances and even the intensification of harmonic distortions at the connection point between the wind farm and the external network. Therefore, this paper aims at evaluating the impacts of tuned harmonic filters on grid resonance characteristics and harmonic distortion levels from a wind farm. In this way, based on measurements of currents from an existing Brazilian wind power plant, computational studies are performed in accordance with the guidelines given by Brazilian regulations.

Analysing renewable energy flow distribution and its influence on grid electricity prices
Authors: Vladislav O. Samoylenko  , Andrew V. Pazderin  , Sergei A. Bychkov
Published: September 2020

The paper presents an approach to the assessment of technical and economic efficiency for an electric energy (EE) transport in a distribution grid. It is focused on the extent of renewable energy sources (RES) integration efficiency according to energy prices in a grid. A two-step procedure for calculation is used in terms of the approach. The first one includes the obtaining of energy flows distribution in a grid. The next step provides the calculation of costs flows and nodal prices for electric energy. Both stages are performed using a developed branch flow model. Unlike power flow distribution describing the instant point of time, energy flow distribution developed for any operation duration deals with the integral values of the flows. This is of great importance for the deeply varying output profiles of the intermittent renewables. The model provides the direct utilization of electric energy meters data available in a grid. The approach presented is essential for locating the particular consumers of the renewable energy in terms of a grid’s deep state and circuit diversity as well as for analyzing the influence of a renewable energy for electricity prices, and estimating the necessary renewables’ levelised cost of energy (LCOE).

Published: September 2020

Usage of not conventional and renewable energy sources (NCRE), as photovoltaic plants, to generate electricity and self-consumption of residential areas, shops and industry, is known as distributed generation. The present research aims to design a photovoltaic solar plant of 1.5 MW to be ground mounted. It will be interconnected with the bar of the substation of the local distributer of electricity in medium tension. The project is explained from its beginning, including site description of the terrain chosen, solar irradiation data, distribution and inclination of solar panels, electrical connexion among the panels, and inter-connection with the local distributer. The calculated production of the planned solar plant would be near 2.5 million of kWh, having taken into account the technical loss of energy in about 3.5 % including all loss sources. Finally, economic study has been carried out to obtain a return period for the investment of only two years, with an estimated profit, in the 20 years of the solar plant life, of about 15 million USD. In conclusion, it is possible technical and economically to invest in this solar plant, but it would be also desirable for ecological and social reasons.
Enhancing Power Flow with Dynamic Line Rating Effect Using Model Predictive Control
Authors: Abdelrahman Sobhy  , Tamer F. Megahed  , Mohamed Abo-Zahhad
Published: September 2020

Due to the high penetration of renewable energy "solar and wind", the overhead transmission line (OHTL) overloading problem arises, consequently the uncertainty increases. This makes it difficult to operate the energy system without violating the OHTL ampacity rating. To solve this problem, new transmission lines are created, which are costly and require considerable time. In the power system operation, the OHTL ampacity rating is maintained constant for all year, to ensure the safety and security of operation. However, OHTL is not used efficiently most of the time. Therefore, the dynamic line rating (DLR) is presented to ensure better utilization of available assets and to postpone the need to build new infrastructure. This paper introduces the power flow by considering the DLR characteristics of OHTL based on changes in the line ampacity due to the high penetration of intermittent sources. This paper provides a predictive control model to combine the effect of the expected DLR with the energy flow. The artificial neural network (ANN) is introduced for forecasting the DLR as a function of the conductor temperature, ambient temperature, wind speed, and solar radiation. Model predictive control (MPC) is used to control energy flow and DRL is used as a constraint in the control technique. The main features of MPC are the ability to reduce the disturbance and simple controls.

Published: September 2020

The electrical distribution system is facing undesirable power quality disturbances due to different types of linear/nonlinear loads on the supply system. The objective of the project is to reduce the distortion level in voltage or current input to the load and at the output of the filter. To design a simple but highly viable hybrid active power buffer that is capable of feeding less distorted voltage to the nonlinear load model. To present an optimal controlling of these buffers so as to minimize the voltage distortion by designing a different algorithm for the same. Comparing the THD levels of the output voltage waveform with the standard controlling method with the proposed control design to further enhance the proposed design such that it is practically feasible to be implemented in grid system having renewable energy resources. In this work, a power filter has been designed using different algorithms with an objective to reduce the Total Harmonic Distortion in the voltage output waveforms. The total harmonic distortion in the voltage output waveform being fed to the load using only the PQ_RLS algorithm is found to be 2.18 %. In the case of the output voltage from the power buffer using PQ_RLS algorithm, the THD level is 0.17 %. The distortion level in the output voltage waveforms in both the cases being fed to the load when compared, it is found that RLS algorithm in combination with PQ algorithm is more effective in reducing the distortion as compared to standard RLS method or PQ method.

AbstrakKarya seni mural berkemungkinan dapat mendorong meningkatkan kepariwisataan, hingga sejalan dengan meningkatnya perekonomian suatu masyarakat atau perihal lainnya. Namun, persoalannya ialah karya seni mural bertentangan dengan suatu ketentuan, khususnya sebagaimana yang terdapat dalam syariat Islam. Secara jelas dinyatakan dalam syariat Islam, dilarang membuat gambar yang menyerupai makhluk yang bernyawa atau memiliki ruh, seperti gambar manusia dan hewan. Akan tetapi, gambar tersebut dapat ditemui di pagar dan dinding-dinding rumah warga di bantaran Krueng Dho dan Krueng Daroy, Kota Banda Aceh. Faktanya, Aceh merupakan satu-satunya provinsi di Indonesia yang menjadikan syariat Islam sebagai landasan hukum Peraturan Daerah. Tujuan penelitian ini tidak bermaksud ‘memperuncing’ kontradiktif tersebut, melainkan ingin mengetahui pandangan masyarakat terhadap karya seni mural dari perspektif Islami dan berbagai kemungkinan dampak lainnya. Guna mencapai tujuan tersebut, penelitian dilaksanakan dengan metode deskriptif kualitatif. Data dikumpulkan dengan cara observasi, melakukan wawancara – terencana maupun tidak terencana – kepada masyarakat yang dianggap relevan, serta studi pustaka. Kemudian hasil penelitian dibangun berdasarkan analisis terhadap data, paparan bagaimana resepsi masyarakat terhadap karya seni mural dari sudut pandang syariat Islam.Kata Kunci: syariat Islam, mural, kontradiktif, resepsi.AbstractMural art is most likely to be able to encourage increased tourism, so that it is in line with plans to increase people's income or other matters. However, the question is the mural art which is opposed to the provisions, especially those relating to Islamic law. Clearly stated in Islamic Shari'a, released images are released that have life or spirit, such as pictures of humans and animals. However, the picture can be found on the fence and walls of the houses of the residents on the banks of Krueng Dho and Krueng Daroy, Banda Aceh City. In fact, Aceh is the only province in Indonesia that makes Islamic Sharia a legal basis for Regional Regulations. The purpose of this study is not to discuss 'trusting' these contradictions, discussing the public about mural works from an Islamic perspective and various other perspective changes. In order to achieve this goal, the study was conducted using descriptive qualitative methods. Data is collected by observation, conducting interviews - unplanned - for the community considered relevant, as well as literature study.

Institutional Features of the Activity of Chinese People’s Political Consultative Conference
Authors:   Kazan (Volga Region) Federal University, Yan Liu
Published: September 2020

The present study examines the institutional frame-work for functioning of the Chinese People’s Politi-cal Consultative Conference (CPPCC) as an organi-zational form of deliberative mechanisms for making political and administrative decisions. The aim of the author is to determine the role of this social and political association in the state system of the Peo-ple's Republic of China (PRC), to establish con-sistency of such an institutional criterion as the le-gitimizing nature of the CPPCC activities. The author used a historical method (for analyzing the evolu-tion of the CPPCC functions), as well as institutional and comparative approaches (comparing the CPPCC with a similar institution of the Russian Federation). As a result, the author states that the considered socio-political association should not only unite different political forces on its basis, but also devel-op sentiments of patriotism in democratic parties, as well as among non-party leaders, determined by the Constitution of the PRC.
