Universitas Atma Jaya Yogyakarta is a university in Yogyakarta, Indonesia, which was affiliated with the Universitas Katolik Indonesia Atma Jaya in Jakarta. It was established on 27 September 1965 by the Yogyakarta branch of the Atma Jaya Catholic University Institute of Indonesia. The founders of the University were R.A. Soehardi, A.J. Liem Sioe Siet A., Sutijoso, Oey Liang Lee and Leo Sukoto. Originally an extension of the Universitas Atma Jaya in Jakarta, it became an independent University under the auspices of the Slamet Rijadi Foundation on 31 August 1973. The University originally borrowed classrooms from the IKIP Sanata Dharma, now the Universitas Sanata Dharma, until the University's own campus buildings, located at Mrican Baru Street, were finished in 1980.Growing student numbers led to the Faculty of Engineering and the Administration department being moved to a new building in Babarsari Road in 1990, in conjunction with the celebrations of the silver anniversary of the founding of the University. In 1995, the Economics Faculty and the Postgraduate Program moved into a new building beside the existing building in Babarsari Road. In 2005 a new building was built adjacent to the Faculty of Engineering and the Administration department to host the Faculty of Social and Political Science. The University also acquired the former BHS Bank building to host administrative department. A new integrated library 4 story building has been built next to the Faculty of Social and Political Science building. It will host library and Information Systems Center. The Library building is officially open in a mass led by Mgr. Ignatius Suharyo on October 2009.In late 2010, an additional project to build new building was started. It is planned as an additional to the existing Faculty of Social and Political Science Building. The new building is situated on the east of the current building.The motto of the University is "Servien in lumine veritatis" .The Rector for 2007-2011 period was Prof. Dr. Dibyo Prabowo, M.Sc with 3 vice rectors Dr. A. Koesmargono , Mr Luddy Indra Purnama , and Mr A. Siswanto as acting vice rector for Students, Alumni, and Cooperation. In early 2009, Mr. A. Siswanto was replaced by Mr Hestu Cipto Handoyo, the position vice rector for Students, Alumni, and Cooperation became permanent .On 19 August 2009 Prof. Dr. Dibyo Prabowo, M.Sc. died after a week in hospital due to a heart attack. Dr. A. Koesmargono was appointed as acting rector. Eventually, Dr. Koesmargono is elected as rector after defeating 2 other candidates in an election. Dr Koesmargono will serve as rector for the remainder of Prof. Dibyo Prabowo's term . Professor Yoyong Arfiadi is appointed vice rector to fill position left vacant by Dr. Koesmargono.In December 2010, Rector election is held. There are two candidates, Dr Koesmargono and Dr. R. Maryatmo, MA . The University's Senate will vote for 2011-2015 Rector on December 16, 2010.UAJY is one of the 50 most promising university and one of the best six universities in Indonesia in term of quality assurance according to Directorate of Higher Education, Department of National Education.

A nonlinear finite element analysis of R/C hybrid deep T-beam with web opening subjected to pure torsion is presented. Hexahedral 8-nodes and space truss element were used for modeling concrete and reinforcement. The reinforcement was assumed perfectly bonded to the corresponding nodes of the concrete element. The constitutive relations for concrete and reinforcement are based on the modified field theory and elastic perfectly plastic. The smear crack approach was adopted for modeling the crack. The torque-twist angle relationship curve based on the finite element analysis was compared to the experimental results. The comparison shows that the curve of torque-twist angle predicted by the nonlinear finite element analysis is linear before cracking and close to the experimental result. After cracking, the curve becomes nonlinear and stiffer compared to the experimental result. Copyright © 2013 Techno-Press, Ltd. Source

The current paper aims to understand the experience of NGOs in Indonesia to develop participatory democracy by the use of Internet. The research focuses on cases study of three NGOs in Indonesia: WWF-Indonesia, WALHI, and Combine Resource Institution (CRI). The results show that the main strategic uses of Internet of the NGOs are varied. There are similarities regarding the main characteristics of Internet internal use within the NGOs. Internet is mainly used for communication and collaboration, workplace participatory democracy; and consumption and production. Information is the main characteristic of Internet use by NGOs. Mutual relationships between internal and external use of the Internet exist, as found at WWF-Indonesia and CRI. However, the use of Internet for workplace participatory democracy (internal) does not correlate to the development of public participatory democracy (external). The paper concludes that Internet is a potential medium for participatory democracy because it contributes to the main characteristics of participatory democracy. NGOs in Indonesia develop participatory democracy by creating websites, mailing list or forum. However, different strategic uses of the Internet exist, so the implementation and achievement in respect to stimulating participatory democracy are varied. Citizen journalism or community-based journalism is effective medium to develop participatory democracy. Source

Theoretical and Empirical Researches in Urban Management | Year: 2010

This study has been focusing on the vulnerability of street vendors in Java since the time when Java was hit severely by the economic crisis in 1997/1998, which also had reversed the trend of economic formalization in Indonesia. For this aim, a survey was conducted during the month of February 2007 in Yogyakarta and Sleman districts in Yogyakarta Special Province. The survey covered 122 street vendors in several streets in both areas. These samples consist of three groups of street vendors: food seller, non-food seller, and services providers. Based on this survey, vulnerability index of street vendors is measured. The study found that most of street vendors in Yogyakarta experience vulnerability at the medium level. In general, vulnerability of food seller vendors is higher than other vendors. Vulnerability also varies across the locations of vending. Source

This paper discusses a class of group-based particle swarm optimization (GBPSO) used for figuring out admissible velocities on the three-degree Bezier-based path. Constraints of maximum allowable radial and tangential accelerations and tangential velocities are considered. The proposed method is designed for performing minimum-time collision-free trajectories in a multiple-vehicle system. The problem of minimizing the reaching time of the slowest vehicle is addressed. Additionally, the problem of generating the velocities of individual paths based on parameter and time (i.e., radial and tangential velocities) is presented as well. A particle group represents a set of particles containing the path's two control points of each vehicle. The searching process executed by the GBPSO can be described as searching the suitable control points that perform minimum time trajectories. The first and last two control points are used as the state vector of a single particle. The proposed method has advantages in shortening velocity profile generation time and thus enhances the searching time. The results of a simulation demonstrating the performance of the proposed GBPSO also are presented. © 2015 Institute of Control, Robotics and Systems - ICROS. Source

Structural optimizations have received great attention from structural engineers. Several optimization methods have been proposed including evolutionary strategies and genetic algorithms. This paper considers hybrid genetic algorithms for roof truss optimizations. Practically, roof truss optimizations are unique. In this case, the pitch angles are usually governed by roof covering types. In the optimization process, the pitch angle is set to constant, while the coordinates of the joints are determined by genetic algorithms. The optimization process utilizes hybrid genetic algorithms, i.e., a combination of binary and real coded genetic algorithms. Genetic algorithms are optimization methods that have been used successfully for various problems. For the sizing, shape and topology optimizations considered in this paper, the area of cross section and the number of members connected to every node are optimized using binary coded genetic algorithms, while the coordinates of the nodes are determined using real coded genetic algorithms. The optimization process for binary and real coded algorithms is done subsequently. The use of real coding for joint coordinates of structures gives the program the flexibility to obtain the final position of the joints. The arithmetic crossover is used to tackle this matter. In every generation, a portion of new individuals is inserted randomly replacing the old individuals. This can be considered to increase the variability of the population. In addition, the fittest individual is always transferred into the next generation. The penalty to the individuals that are violating the constraint is set to a minimum fitness in this paper. It can be shown that the proposed procedure is able to obtain the optimum design of roof truss structures. © 2014 The Authors. Published by Elsevier Ltd. Source
