Jakarta's Christian governor Basuki Tjahaja Purnama (C), popularly known as Ahok, was jailed for two years on May 9 after being found guilty of committing blasphemy, capping a saga seen as a test of religious tolerance in the Muslim-majority nation (AFP Photo/BAY ISMOYO) Jakarta's Christian governor, who was jailed for blasphemy Tuesday, won much praise for his efforts to clean up the traffic-choked megacity but his popularity could not save him from Islamic hardliners angered by his comments about the Koran. With his outspoken, combative style and can-do attitude, Basuki Tjahaja Purnama cut an unusual figure among the political elite in Muslim-majority Indonesia, where politicians typically take a more gentle, persuasive approach. But the tall, bespectacled politician, who was the city's first non-Muslim governor for half a century and first ever ethnic Chinese leader, quickly overcame any doubts about his leadership as he took concrete steps to improve the city of 10 million. The 50-year-old -- known by his nickname Ahok -- regularly railed against corruption in one of the world's most graft-ridden countries and led sting operations to catch lazy bureaucrats, drawing praise from a public weary of the city's inefficiences. The former deputy governor inherited the top job in 2014 after his predecessor Joko Widodo won the presidency. On Purnama's watch, roads were repaired, pavements improved, more parks started appearing in the city and its notoriously filthy rivers were cleaned up. Some of his policies -- particularly a drive to evict poor, riverside communities -- caused anger, but many Jakartans said their lives had changed for the better since he took power. Until the blasphemy controversy, he was favourite to win last month's gubernatorial election in Jakarta. Aleksius Jemadu, a political expert at Pelita Harapan University near Jakarta, praised Purnama for his "courageous attitude". "Ahok is a rare figure, he's fearless. He appeared when the Indonesian people were thirsting for an honest leader," he told AFP. But it was never going to be easy for someone from a religious and ethnic minority to hang on to such a powerful position, particularly when he was not elected to it in the first place. His aggressive, outspoken style, an advantage when taking on bungling officials, turned out to be a double-edged sword that contributed to his downfall. In September last year, in a speech to a group of fisherman during early campaigning for the elections, he accused his opponents of using a Koranic verse to trick them into voting against him. The comments were filmed and went viral online -- providing ammunition for fringe hardline groups who had long railed against a non-Muslim leader ruling the capital and his political opponents who were keen to oust him from the job and embarrass his ally Widodo. Despite his apologies and insistence that he only intended to attack his rivals, not the Koran itself, hundreds of thousands of conservative Muslims took to the streets of Jakarta in mass rallies last year, organised by hardliners and encouraged by his rivals. Under intense public pressure, authorities put him on trial for blasphemy and his popularity slumped. He lost last month's election to a Muslim challenger and Tuesday was jailed for two years for blasphemy, a shock decision after prosecutors recommended only probation. Purnama was born into a well-off family on Belitung island in western Indonesia, and studied geology at university in Jakarta, before returning to his village and going into business. His father urged him to use his talents to help those less fortunate than himself, and he entered local politics in 2004. He was elected to the national parliament in 2009, where he met Widodo.

PT Anugrah Citra Boga is a food processing industry that produces meatballs as their main product. The distribution system of the products must be considered, because it needs to be more efficient in order to reduce the shipment cost. The purpose of this research is to optimize the distribution time by simulating the distribution channels with capacitated vehicle routing problem method. Firstly, the distribution route is observed in order to calculate the average speed, time capacity and shipping costs. Then build the model using AIMMS software. A few things that are required to simulate the model are customer locations, distances, and the process time. Finally, compare the total distribution cost obtained by the simulation and the historical data. It concludes that the company can reduce the shipping cost around 4.1% or Rp 529,800 per month. By using this model, the utilization rate can be more optimal. The current value for the first vehicle is 104.6% and after the simulation it becomes 88.6%. Meanwhile, the utilization rate of the second vehicle is increase from 59.8% to 74.1%. The simulation model is able to produce the optimal shipping route with time restriction, vehicle capacity, and amount of vehicle. © Published under licence by IOP Publishing Ltd.

This current paper will present a research proposal with regard to the effect of stress on virtual teams. The proposed research will specifically concentrate on the virtual teams’ stress as double constructs (positive stress as the challenge and negative stress as the hindrance), cohesion as social support to mitigate the stress, and how these three factors will affect the virtual teams’ knowledge sharing, satisfaction, and performances. A study which incorporates an experimental research methodology will be specifically proposed to test the aforementioned relationships. Related literature reviews on stress, hypotheses development, as well as experimental research design will be mentioned in the paper. © Springer International Publishing AG 2017.

We report a theoretical study on the characteristics of a commercial photonic crystal fiber claimed to be endlessly single mode, i.e. the LMA-15 fiber. The study was carried out using a finite element leaky mode solver. By using a loss discrimination between the fundamental and higher order leaky modes as a multi/single-mode criterion, we obtained that the fiber is obviously multimode in short wavelengths, even for long length beyond the practically usable length of the fiber. © 2010 Elsevier B.V.

This paper shows that our novel method, Virtual Detection Zone (VDZ) system with CCTV snap shots can provide the empirical data needed to construct Fundamental Diagrams and to calibrate a chosen model. VDZ system is better than the traditional system which uses loop detectors, as it is able to show zero speeds at totally jammed density, which is an essential parameter for macroscopic traffic model. Real data set have been obtained by using only seven VDZ agents who have carried GPS enabled smart phones, together with snapshots from fifteen existing CCTV, on Tangerang to Jakarta highway (a distance of 21 km). The test, carried out without the use of any intrusive sensors, has produced data which is in agreement with previous traditional method. By adopting and modifying Cell Transmission Model or CTM, a variant Macro model, it is shown that simulated speeds for AM cluster generated by CTM can be calibrated to follow real traffic data. Its Mean Absolute Percentage Error or MAPE can be improved from 93.8 to 48.8% and improved further by 5.1% using type test method. © 2015 IEEE.

We investigate a dynamical system having a special structure namely a codimension-one invariant manifold that is preserved under the variation of parameters. We derive conditions such that bifurcations of codimension-one and of codimension-two occur in the system. The normal forms of these bifurcations are derived explicitly. Both local and global bifurcations are analyzed and yield the transcritical bifurcation as the codimension-one bifurcation while the saddle-node-transcritical interaction and the Hopf-transcritical interactions as the codimension-two bifurcations. The unfolding of this degeneracy is also analyzed and reveal global bifurcations such as homoclinic and heteroclinic bifurcations. We apply our results to a modified Lotka-Volterra model and to an infection model in HIV diseases. © 2015 World Scientific Publishing Company.

Product Line Architecture is the key success of Software Product Line Engineering. Product Line Architecture prepares the design of architectures for members of product line. Architecture design is the most essential activities of a Product Line Architecture development. It prepares the corner stone of variability decision. The architecture design need to produce specific architecture from product members' assets in a Software Product Line. Representing variability explicitly is the most challenging one. Moreover, the architecture must cope to the diversity of products, and take the behaviour into account. This paper introduces some approaches to address the architecture design problems. Features' grouping with specific concern is the starting point. Then, models the component and interaction element composition, based on its capability. This paper also introduces logics that link the interaction element and component. Using layers, the product line architecture can be established. © 2011 IEEE.

Strut-and-Tie models are well-known worldwide as valuable tool in designing D-Regions of Reinforced Concrete members. It has been adopted in many Concrete Structural Codes in many countries. Recently strut-and-tie-models have been included in Indonesia Concrete Structural Code (SNI-03-2847-2012). In this paper, it will be shown how a Strut-and-Tie Model can be developed for various structural concrete deep beams using Evolutionary Structural Optimization. As a tool for this study the author used Bi-Directional Evolutionary Structural Optimization (BESO2D) computer programs, developed by X. Huang and Y.M. Xie . Three tested concrete beams with small, medium, and large opening  will be taken as the case study. It will be shown the optimal topology of a plane stress of continuum structures produced from BESO2D can be taken as the basic strutand- tie-model. For design process the best strut-and-tie-model can be delivered from the optimal topology structure only with the deep knowledge of the basic load transfer from loading to support point. © 2015 The Authors.

Background: Spinal cord injury (SCI) is a devastating condition, which beleaguers its victims with long-term health issues. Nerve transfer is a feasible option for restoration of critical limb function in patients with SCI that potentially improves independence and quality of life. Methods: This article delineates the general principles of nerve transfer and its specific application pertinent to SCI. The available nerve transfer strategies are described based on the targeted limb function, mostly involving critical upper extremity function. The role of nerve transfer for paraplegia, diaphragm reanimation, and bladder reinnervation is also discussed. Results: Nerve transfer offers several advantages over the traditionally used tendon transfer. Conclusions: Nerve transfer does not require prolonged immobilization and provides greater functional gain for a given transfer. Reconstruction of several facets of upper limb function potentially can be performed in a single stage. The merits of nerve transfer deserve further study to evaluate its value for spinal cord injury in humans. © 2013 Elsevier Inc. All rights reserved.
