Keywords: embryo rescue; seed dormancy; scarification; Globba seed
Abstract
Young Globba winitii seeds at 20 days after pollination were collected and trimmed at different parts of their seed coat, then cultured on MS medium supplemented with 10 mg/l BA, 1.0 mg/l NAA, 10 mg/l GA3 and 30 g/l sucrose. The results showed that the trimming method could break dormancy, and young embryos germinated in the first week. Seeds trimmed down to a naked embryo had the highest germination rate, germination index and speed of emergence, which were 98%, 22% and 100%, respectively.

Keywords:Highlighting; Colour Contrast; Adobe Photoshop; Brightness/Contrast application; Contours Deformation; and Shapes Distortion
Abstract
Interior designers are quite cognizant of the colour significance as a basic element of design, in order to achieve aesthetic and functional demands. This paper aims to present an empirical model for interpreting the relationship between the colour’ contrast and highlighting the foreground objects, by measuring the values of the deformation via using Adobe Photoshop software. The experiment contained practical steps of calculation and analysing the amount of the chromatic deformation of the foreground objects, which is represented by 6 samples model. These samples of coloured spots are tested within two phases; with coloured background based on Itten colour wheel, and with a neutral background “greyscale wheel”; and comparing the results by calculating the amount of distortion, through measuring angle's values. The findings showed that using of contrast application is useful as an empirical method for scaling the chromatic interaction between the foreground and the background. By using T-Test analysis the findings emphasized that the colour contrast had a significant impact on highlighting or distorting the foreground shapes.

Keywords:Highlighting; Terraced House; Facade; Shading Area; Sunlight Penetration; Malaysia.
Abstract
The aim of this study is to evaluate shading performance and the extent of sunlight penetration on the front house facade of the earliest terraced houses in Malaysia built in 1950s. Two house facades are selected for the case study located in Petaling Jaya Old Town, the first Garden City’s new town in Malaysia. The survey applies sunlight simulation technique using the SunTool programme. The simulation calculates at hourly interval from 7.00am to 6.00pm. The study finds that terraced house facades built in 1950s do not sufficiently design to tackle the house facade exposed to direct sunlight. The emphasis of façade design built in 1950s is more on the architectural style rather than designing efficient shading devices to tackle direct sunlight penetrating to the façade wall and windows. Roof overhang and recessed wall with balcony are the horizontal shading elements commonly used in the house façade design. No vertical shading device was applied to the façade design during 1950s.

Abstract
An in vitro propagation system was developed for comparison of six varieties of young globba embryos cultured on MS medium supplemented with various concentrations of BA. The result showed non significance Duncan’s multiple range tests. The G-75, G-52, G-08 and commercial white varieties, cultured on MS medium supplemented with 5 mg/l BA, gave the highest average number of new shoots.

Keywords: Bridge Design; Bridge Failure; Bridge Structure; Bridge Model; Structural Contest, LRFD, THAILAND
Abstract
This work presents the processes, scoring system, and observation of the Thailand’s College Steel Bridge Truss Models 2011 Contest. For Thammasat University (TU) Bridge Design team model, we applied the load and resistance factor design (LRFD) of bridges [1], [2]. Prior, the AASHTO LRFD Bridge Code was reviewed which included investigation into the design code’s background documentation [3]. For this contest, the bridge models must be the steel bridge truss structures with span lengths 5 meters. All structural members must be the rolled-steel shape members. The scoring system for the contest is comprised of four categories: 1) Construction Speed Score, 2) Economy Score which is consisted with two parts that are the labor and material costs, 3) Structural Stiffness Score, and 4) Structural Efficiency. Types of truss failures have been observed.

Keywords: Religious Building; Cultural Heritage; Conservation; Socio-cultural effect
Abstract
The issue of heritage buildings is an important part in the development of a city. Historic buildings have high value tourism, if managed properly. Unfortunately, the government is less concerned about the presence of historic buildings. Urban development is more focused on commercial activities and generates high revenue for the region. Many historic buildings in the city of Jakarta is not properly maintained. Several historic buildings that have religious values often lead to conflict. The buildings are supposed to have an atmosphere of worship and sacred environment, even more immersed in line with the development of the city. This study is to identify the problems of the religious cultural heritage buildings in Jakarta that will be processed based on the Physical Components and Socio-Cultural Components. The result of the study is the mapping of potential problems and give solution about a model of cultural heritage buildings in the area, especially religious building. This model hopefully can solve the problem of disharmony between the religious value of cultural heritage buildings and its environment surrounding.

Using Adobe Photoshop to Scale the Rate of the Shape’s Deformation By Colour Contrast Application
