Swarm Intelligence Based Multi-phase OPF For Peak Power Loss Reduction In A Smart Grid
Recently there has been increasing interest in improving smart grids
efficiency using computational intelligence. A key challenge in future smart
grid is designing Optimal Power Flow tool to solve important planning problems
including optimal DG capacities. Although, a number of OPF tools exists for
balanced networks there is a lack of research for unbalanced multi-phase
distribution networks. In this paper, a new OPF technique has been proposed for
the DG capacity planning of a smart grid. During the formulation of the
proposed algorithm, multi-phase power distribution system is considered which
has unbalanced loadings, voltage control and reactive power compensation
devices. The proposed algorithm is built upon a co-simulation framework that
optimizes the objective by adapting a constriction factor Particle Swarm
optimization. The proposed multi-phase OPF technique is validated using IEEE
8500-node benchmark distribution system.Comment: IEEE PES GM 2014, Washington DC, US
Synthesis, Characterization, and Properties of Mononuclear and Dinuclear Ruthenium(II) Complexes Containing Phenanthroline and Chlorophenanthroline
The study of photophysical and photochemical properties of ruthenium complexes is of great interest for fundamental practical reasons. Ruthenium complexes have been investigated for use in artificial photosynthesis. This paper deals with the synthesis and spectroscopic investigation of custom-designed ruthenium complexes containing phenanthroline and chloro-phenanthroline ligands. These complexes maybe useful for biological electron-transfer studies. The heteroleptic ruthenium monomer complex Ru(phen)2(Cl-phen) (where phen = 1,10-phenanthroline and Cl-phen=5-chloro-1,10-phenanthroline) was prepared in a two-step procedure previously developed in our laboratory. This monomer complex was used to prepare the ruthenium homometallic dimer complex, (phen)2Ru(phen-phen)Ru(phen)2, by utilizing the Ni-catalyzed coupling reaction. Both complexes were purified by extensive column chromatography. The identity and the integrity of the monomer complex were confirmed by elemental analysis. The calculated and the experimental values for the elemental analysis were in good agreement for the monomer complex. UV/Vis absorption spectroscopy, emission spectroscopy, and cyclic voltammetry were used to investigate the properties of both the complexes
Model Fisik Bangunan Pengaman Pilar Jembatan Akibat Aliran Debris
Debris flow generally occurs in rivers in mountainous areas. This flows is a very dangerous and
destructive. This happens because the debris flow has a high speed and carry a mixture of
sediment and other materials. Of infrastructure is built on rivers area flow pattern makes the need
for special handling to maintain the protected structure with a substantial investment. This study
focuses on the modeling and observation influence debris flow on bridge piers with three (3)
conditions: unprotected bridge piers, using gabion protection, and bored pile protection on the
model.
By using a discharge of 1.54 liters/sec on a scale model of the maximum scours depth is obtained
that occurred on bridge piers unprotected condition, that is equal to 1.7 cm and the minimum
scours occurs in conditions of safety piers the bored pile is equal to 1.48 cm. The maximum scours
volume occurs in the downstream bridge using gabion protected, amounting to 400 cm 2 , while the
minimum volume of sediment scours occurs by using a safety bored pile 257.5 cm 3 . By the using
protected piers bored pile more effective to resist scours due to debris flows. This is due to the
construction of bored pile does not impede the flows that occurs so that the effect scours will
reach a point of equilibrium
Implikasi Pemilihan Kepala Daerah Langsung Terhadap Mekanisme Hubungan Kerja Baru Kepala Daerah Dan Dprd
This study is intended to understand and analyze the implications of the direct local head election on the work relation between the new local head and the local parliament in establishing local regulations and local budget, and the monitoring on the local government in general and, especially the mayor of Malang made by the local parliament. Therefore, the approach employed was a normative approach which was supported by sociological approach. Based pm the results and analyses made, it is known that the relation between the local parliament and the local head merely gives grammatical implication in establishing local regulations, and in making the local budget, the role of the local head is more dominant, while in terms of monitoring made by the local parliament, it is not as strong as before or when the local head was elected through the mechanism of local parliament in accordance with the law no. 22. in the year of 1999

Kontribusi Keluarga terhadap Pembentukan Karakter Anak (Studi Perspektif Modal Sosial di Kota Parepare)
This article analyzed empirically about education character that was applied and developed by success family toward children education, the education that concern on social modal development. Family has function to lay the strong basics about social modal values that are needed by the children. When all of the elements of characters are absorbed by the children, then it becomes integral part in personality reconstruction, basically is the interaction result from system and behavior patterns that practiced by the parents. Family education basic determined the child succeed, depended on behavior patterns and interaction that developed by the parents. Family which has strong behavior patterns created the religious climate is the family that can make a role in an optimal fashion in developing the education of social modal oriented. While the family which is developed liberal behavior patterns, authoritative and ignored the religious climate, showed the low indication of role and function towards social modal development
Problematika Mewujudkan Keadilan Substantif Dalam Penegakkan Hukum Di Indonesia
Theoretically, the problems deal with the attitude of the law enforcers, especially the judges, to take sides in considering the procedural or substantive justices. The 1945 Constitution or the legislation on the justice power and on Constitutional Court of Law actually oblige the judges to realize the substantial justice in law enforcement. The judges are not the sounders of the laws, since human beings are never able to make perfect legislation. It is the judges who should interpret the legislations in order to realize the substantial justice
Analisis Karakter dan Kearifan Lokal dalam Pembelajaran Sosiologi di Kota Banda Aceh
This study aims to discuss the problems in the integration of character and wisdom in sociology learning. The study was conducted in the city of Banda Aceh. The results show that many teachers do not understand and have not mastered the way to make a lesson plan that is loaded with local values. Learning is not yet based upon lokal wisdom, even some teachers argued that the material of lokal values is not necessary for various reasons. Teacher empowerment is still minimum. Therefore, the mandate of Qanun ( regulation ) No. 5 of 2000 , Qanun No. 6 in 2000 and UUPA No. 11 2006 on Regional Government of Aceh for adoption of lokal wisdom has not been achieved. © 2013 Universitas Negeri Semaran
Learning Materials in Character Education
Since in 1976, sociology officially became one of the subjects taught in senior high school programs throughout Indonesia. There are still several major problems in teaching it in particular the lack of locally relevant teaching materials and the lack of teachers with a background in sociology. The aim of this study is to find better ways for the teaching of sociology and for students to learn the principles of sociology and to find the best of teaching materials available for constructing a better paradigm for character education and also to identify the various barriers and difficulties inhibiting the provision of highly successful character education through the study of sociology. Most of the results showed that in teaching sociology in Banda Aceh the implementation of teaching character based on local wisdom has major problems and obstacles. In particular the standardized national education program ending with standardized national final examinations emphasizes rote learning unrelated to the real life of the students. This raises contradictions because the centrally prepared material makes it difficult to introduce local indigenous values, culture and traditions
