    The project chosen by the author is a terminal facility which is located at Pinang Baris Terminal. The Pinang Baris Terminal serves public transport vehicles with a route west to the Nanggroe Aceh Darussalam (NAD) Region. The problems found were unified vehicle circulation, less strategic departure and arrival areas, and a lack of a number of standard facilities not found at the Pinang Baris Bus Terminal, such as the absence of a health post, bus maintenance and washing areas and the absence of barriers between vehicle traffic and passengers. Other facilities required by the regulations are available, although not all of them function properly, many of the facilities are damaged or unused, such as waiting rooms which are rarely used by passengers while waiting for the bus. On this project which is the scope of the design consists of designing the terminal in accordance with the regulations, laws and provisions of the Government, redesigning the Pinang Baris Terminal according to the predetermined land area, and expanding the terminal. In designing this project, the authors apply and follow the laws and regulations regarding terminals in design, so that the Pinang Baris Integrated Terminal can become a terminal that complies with terminal standards. With this application to the project, it is hoped that the author will be able to produce design solutions that can provide comfort for users and make the Pinang Baris Integrated Terminal a standard-compliant terminal108 HalamanSkripsi Sarjan

    Analysis of fluidization behavior in the loop-seal of a circulating fluidized bed gasifier using particle-in-cell method

    The loop-seal (LS) of a circulating fluidized bed (CFB) reactor is the heart of the system and is still under consideration due to complexities in both two-phase flow and the geometry. The LS controls the solid circulation rate (SCR) of particles that is crucial for the stable operation of a CFB system. In this study, the effect of the aeration rate on the circulation rate of two-chamber LS for a 10 MWth CFB gasification system is examined. The influence of aeration rate supplied to the recycle and the supply chambers of the LS is investigated in detail with 44 different cases using computational particle fluid dynamics (CPFD) method. Barracuda VR software is used to model the whole CFB system with non-reacting isothermal flow assumption. The solid circulation rates are investigated for various aeration rates corresponding to different operating regimes. The stable and unstable operating conditions are identified according to monitored pressure fluctuations. Moreover, three regimes are revealed based on the analysis of differential pressure between two chambers of LS. It is found that the region for the stable operation, corresponding to higher SCR and lower pressure fluctuations, exists for a certain range of aeration rates and the aeration ratio between two chambers of LS

    This study was conducted to determine how the condition Pinang Baris Terminal currently associated with the characteristics of parking. This study uses a field survey by direct observation in Terminal Pinang Baris by spreading surveyor at certain points in order to facilitate the recording of data in order to obtain a valid observation. Direct observation is done by manually recording the arrival time data and exit the bus, license plate number, and the name of the bus company. Research analysis using Microsoft Exel. Results of identification and field research has been on the analysis shows a maximum level of parking characteristics in Pinang Baris Terminal and it is known that there are three issues that must be resolved. First, the buildup of bus parking AKDP manifold small and MPU bus that we can see on the pictures and the documentation of the calculation in the Parking Index. Secondly, the vehicle bus parking AKDP which do not in place and this can be seen in the image documentation. Third, when the AKAP bus will maneuver to get into the parking lot AKAP bus, it takes quite a long time and could hinder other transport to pass. In this thesis, the author has provided solutions to three problems are found, because it must be found a solution that does not affect the operational performance in the future Pinang Baris Terminal

    Combination of Luque instrumentation with polyaxial screws in the treatment of myelomeningocele kyphosis

    Rigid congenital kyphosis in myelomeningocele is associated with an important morbidity with skin breakdown, recurrent infection, and decreased function. Kyphectomy is the classic treatment to restore spinal alignment; however, surgery is associated with morbidity and long-term complications. The purpose of this retrospective study was to examine the authors' experience using combination of Luque instrumentation with posterolaterally placed polyaxial screws in. the treatment of myelomeningocele kyphosis. From June 1999 to June 2003, 7 patients were treated and followed up for an average of 68.6 months. The average age at the time of the operation was 7 year and I month. All patients underwent vertebral excision from just above the apex of vertebral deformity to realign the sagittal deformity. Posterolaterally placed polyaxial screws were used in combination with segmental Luque instrumentation. Kyphotic deformity averaged 104 degrees before surgery, 15.2 degrees after surgery, and 18.5 degrees at the latest follow-up. The average loss of correction was 3.3 degrees. The average blood loss was 611 mL. Complications occurred in 2 of 7 patients were superficial wound breakdown and deep wound infection that required rotational flap closure. Kyphectomy with posterior instrumentation by using Luque technique in the combination with polyaxial screws is reliable method for correcting rigid kyphotic deformity in patients with myelomeningocele. Rigidity of the construct, greater correction capacity, and low profile instrumentation by the help of posterolateral insertion of the polyaxial screws and wiring were the distinct advantages of this technique
