Published: October 2019

Abstract
Higher education in Indonesia, particularly Yogyakarta as City of Education, is continuously growing. Babarsari is one of higher education area with rapid growth and development in Yogyakarta. This area is surrounded by several universities which then form the agglomeration of higher education area. The influence of new activities as a growth pole like this educational activity has led to rapid change on land use and people’s activity. This encourages the potential for high daily movement, especially the movement of students who are the dominant actors in this area. The majority of students are live near the university. However, this not lead to higher use of sustainable modes in this area. This paper tried to reveal the connection between accessibility and travel behaviour in university area. By using samples from three universities in this area (Atma Jaya University, STTNAS Yogyakarta, and UPN Veteran Yogyakarta), result shows that living in university surrounded area did not ensure students to have sustainable travel behaviour, particularly for their campus travel. The lack of non-motorized transport facilities is indicated as the main barrier for students to travel in more sustainable way.

Abstract
The construction of the Ambarawa (Willem I) - Kedungjati railway line by the Nederlandsch Indische Spoorweg Maatschappij (NISM) is for military purposes and the transportation of the plantations of the Dutch colonial government so that it was significant to study. The successful placement of the train station is supported by the structural quality of the station building that was built as well as the city/regional focal point. Then in the development of the regional spatial structure allows a shift in the role of the land route where the railway station building is located.This study aims to examine the placement of Railway Stations in the City Spatial Plan on the Ambarawa-Kedungjati Line because at present the Ambarawa train station still has a strong role because it is the starting point for the development of the city which produces a variety of morphological spatial expressions in the form of a compact form of square shape and Urban sprawl in the form of linear development. The results of the study can be taken into consideration in the planning of the area where the railway station building is placed in line with the development of the city and or district layout.

Authors: Dewi N L P H , Herwangi Y 
Published: October 2019

Abstract
Shopping is one of the important activities that is carried out by the residents to meet their daily needs. It also has some relationship with the built environment condition around the resident’s houses. If the residential area cannot provide the needs of the residents, then the residents will travel out of the residential area, especially using private vehicle. Yogyakarta is one of the city in Indonesia which has a type of settlement that can support sustainable development by increasing pedestrian trips. On the other hand, the number of private vehicles in Yogyakarta always increase year by year. Therefore, the aim of this study is to identify the travel behavior for shopping activity at two kinds of urban settlement which have some differences in their built environment condition. This study is conducted by quantitative method with data collection using questionnaires and it is assisted by field observation. The result of this analysis using Mann Withney U-test shows that there are some differences of shopping travel behavior between urban kampong residents and formal housing residents. However, the chi-square test shows some weak relationships between travel behavior and built environment. In the other words, built environment does not significantly affects the shopping travels in Yogyakarta city, as well as many developed theories.
Analysis on calculation of Vehicle Operating Cost (VOC) at Gejayan intersection before and after fly over ring road operation in Yogyakarta
Authors: Wibisono R E , Cahyono M S D , Muhtadi A 
Published: October 2019

Abstract
Gejayan intersection is located in Sleman Regency of Yogyakarta. Fly Over will be constructed at the intersection in the ring road of Yogyakarta. The nearest intersection to the east is Gejayan Intersection with a distance of 1573.11 meters. Gejayan intersection performance in 2018 has reached saturation by having Level of Service E. The more severe conditions will occur in the next 10-20 years. If it is planned using Fly Over on the ring road in Yogyakarta connecting Gejayan intersection, the vehicles flow must have other alternative by road widening. The most important step is to predict the Vehicle Operating Costs (VOC). After the Fly Over operation, VOC can be calculated to determine the cost saving. The scenario to predict VOC was 80% of vehicle volume would pass the Fly Over, and the 20% would still use the existing road. The results showed that the cost saving of Vehicle Operating Costs (VOC) of the existing road compared to the fly over use in 2019 was IDR 37,941,324,952. In 2039 the saving would be IDR 240,232,694,488. If the road was only widened, the cost saving of VOC in 2019 would be IDR 9,084,204923 and in 2039 would be IDR 72,107,188,198.

Abstract
The station development through transit oriented development principles in favor to transit patronage has emphasized the important of design, diversity and density. However, studies were lacking in identification of the level of combination of all these ingredients toward increasing ridership. Using the node-place balance perspective, the design, diversity and density are re-evaluated. Four transit terminals or stations are used as case study in the City of Surabaya. Each of the transit area is divided into several zones/subzones to evaluate the level of density, diversity and design into the value of node and place index. Each transit points would be regarded as having one among the five categories of node-place index. The level of the daily trip demand is identified as the target variable. Qualitative comparative analysis then is used to mapping the position of each station, suggested the level of combination of design, diversity and density in each node-place category, to explore which combinations that are found to be statistically significant to support the increases of trip demand. The research showed that employment density may has more impact than housing density, while node aspect maybe of more important compare to place aspect that explain high or low trip demand.

Abstract
This paper presents a study to measure the implementation of smart city initiatives in Indonesia that has been applied by the city government in various city scales. Various benefits are believed to be gained by applying a smart city concept that emphasizes on the use of information and communication technology. However it depends on the readiness of the city government and its citizens in implementing the smart city concept. Importance Performance Analysis is used to measure the differences between public perception and the real conditions of the smart city implementation. Surabaya city, which was granted as one of the five winners of smart city awards in Indonesia for big city category, is used as a case study. The implementation of smart city’s attributes is compared with the expectation of the citizens. The result of the research shows that the concept of smart city,which is used and implemented by the city government in providing services for its society is not always understood similarly to the societies’ point of view. Involving the community in determining the priority of which attributes and dimensions of smartness in the provision of public services is very important to improve the level of implementation of smart city.

Authors: Walke G A , Rivankar S N , Verlekar S P 
Published: October 2019

Abstract
Material handling system is the vital pillar of manufacturing industries like food, textile, automobile, wood, and other batch type manufacturing system. Research carried out in past shows that material handling accounts for 36% of production cost. A novel material handling system is developed to cut the cost of material transfer and risk of injury. The proposed system consists a mechanism which can self-propel itself and effect the transfer of raw material from one place to another on a shop floor. Since the system is self-propelled, it eliminates external power source in contrast to other material handling systems. The newly developed material handling system utilizes gravitational potential energy of the material loaded on the system to get self-propelled along a straight line. The system returns to original position by retracing the path after unloading the material at the destination. The system not only reduces the energy consumption for material handling but also reduces risk of injury by reducing human interference. It can be used in small and medium size enterprise (SME) to cause improvement in productivity of plant which has limitation on utilization of resources like labour, energy, land and capital.

Abstract
A lead screw is a mechanical transmission device which transforms rotary motion into translational movement. The main elements are screw and nut which establishes connection among them by the means of threads on respective element. It plays a major role in transferring the load between screw and nut during the travel stroke. This paper investigates the behavior of the lead screw, inside the withdrawal part of the circuit breaker of switchgear, by analyzing the mechanical response of the lead screw system. The various thread parameters such as thread pitch, nominal diameter etc. play an important role in force transmission as well as in overall efficiency of the mechanical system. This study is done by creating models of various thread profile such a square thread, acme thread, trapezoidal thread and simulating the results in the finite element analysis software ANSYS Workbench. This paper focuses on the effect of the thread pitch, nominal diameter, helix angle, screw length on the stress state and deformation within the screw. Also, the influence of screw pitch, screw length and screw nominal diameter on the withdrawal part of the circuit breaker’s natural frequency along its whole stroke is carried out using modal analysis.

Published: October 2019

Abstract
Functionally graded materials (FGM) belong to the class of advanced materials whose properties vary along one or more coordinate. In the present study, an attempt has been made to manufacture FGM beams using a powder metallurgy process. The Al and Al2O3 in powder form are mixed to different volume fraction according to the rule of mixture. These samples are ball milled to form a proper blended mixture and to reduce the particle size for 1 hour at 250 rpm with tungsten carbide balls. A cold compacted die made of AISI D2 steel is used for preparing the sample. Different composition of Al and Al2O3 with Al2O3 varying from 0 to 10% is laid in the die using ethanol as the binder. This sample is compressed using hydraulic press with a load varying from 50-70 ton. The compressed sample is removed using a compression moulding machine, then it is sintered to a temperature of 650°C using a muffle furnace to form a smooth graded Al-Al2O3 FGM beam. Various defects such as surface cracks and bending were experienced during the preparation of samples; these defects were overcome by varying the parameters such as loading and sintering temperature.

Abstract
Handling characteristics of any vehicle refer to its directional control and stability for given steering input. The vehicle parameters such as mass, mass moment of inertia and location of C.G. play a vital role and decide handling response of vehicle under different scenarios. Safe drive is ensured by vehicle’s responses such as yaw rate, roll rate and vehicle lateral acceleration. This paper presents steady state and transient state simulation of XUV 500 model in accordance with ISO 4138 and ISO 3888 test standards using CarSim-Simulink Co-simulation. Influence of changes in above mentioned parameters on Vehicle response during both tests is investigated. Further, control of power train output using torque vectoring is implemented in both tests and its effect on vehicle response is evaluated. The results show that understeer tendency of the vehicle is reduced in steady state test (Constant radius test: ISO 4138). Critical vehicle responses of yaw rate, roll rate, lateral acceleration and path tracking showed improvement during the DLC manoeuvre (ISO 3888) hence, improving stability at higher lateral accelerations.
Gear loss factor using the load distribution model for varying contact ratio in spur gear drive for improved bending strength
Authors: Ravivarman R , Palaniradja K , Prabhu Sekar R 
Published: October 2019

Abstract
Gear loss factor is one of the imperative parameter in estimating the power loss in a meshing gear pair. This paper demonstrates the prediction of gear loss factor parameter in spur gear drive using the load distribution technique. The aptness of two distinct contact ratios is studied and compared in this paper: Normal Contact Ratio (NCR) and High Contact Ratio (HCR). The described model is studied for gearing strength which is improved through profile modification technique. The ultimate focus is to enhance the gearing strength of the pinion in a spur gear drive by discovering the optimal modification point in the tooth profile with at most balanced stresses in the gear pair considered for the study. Using contact analysis, the stresses developed over the contracting surfaces are predicted through finite element method and it is balanced between the gear and pinion. A gear loss factor is predicted along the path of contact for a complete meshing cycle for this balanced drive. It is uncovered that the methodology utilized encourages significant decrease in the gear loss factor of the HCR pair which is confined with the literature models. The values predicted using the load distribution model shows that the high contact ratio gear drive with increased addendum height has the gear loss factor minimum compared with a normal contact ratio gear drive.

Published: October 2019

Abstract
This project aims in the development of Multispeed Gearbox to exhibit low noise behavior during its operation under various load and speed conditions, by optimizing the design parameters with tooth micro-geometry profiles -using Loaded Tooth Contact Analysis (LTCA). Low-noise design is the most important criteria defined by the German customer, for their new 9 -speed gearbox fitted in the high precision tool room CNC Lathes. In loaded condition, gearbox develops noise and vibrations due to the tooth deformations, shaft deflection, internally generated gear tooth loads from non-conjugate meshing action of the gear mesh. Hence selecting the best values during micro-geometry optimization for a multi-speed gearbox becomes complex and needs a unique combination of FEM and analytical tools. LTCA is a very useful optimization tool to study the gear tooth strength evaluations and gear meshing contact characteristics under light and significant loads.
Investigation on Influence of Circumferential Velocity and Lubrication Oil Grades on Scuffing and Thermal Efficiency of Gearbox
Authors: Vaidhyanathan D , Pushparaj A , Mahendran K , Ragunathan V 
Published: October 2019

Abstract
Lubrication oil grades plays major role in reducing the friction to prevent scuffing in gears. Gears transmit power through rolling/sliding contacts between teeth, which must operate reliably for designed life with reduced friction so that there will be minimum wear. Lubrication of tooth contacts, both as a means of minimizing scuffing and as a means of reducing friction due to sliding, is therefore of crucial importance. The circumferential velocity of high speed gearboxes and oil grades plays major role in thermal efficiency of gearboxes. In gearboxes with oil sumps, churning losses contribute for significant portion of the total power loss. Present empirical approaches for examining the churning losses are often limited to certain constraints and operating conditions. Furthermore, they do not provide any information about the oil distribution in the gearbox. In order to overcome these shortcomings, we investigated a steel mill gearbox failure with analytical tools and simulations with the help of renowned software packages and predicted the thermal behavior of the gearbox as function of oil grade and circumferential velocity, also validated later at application.
