The law of construction service (UUJK) No.18 Year 1999 has required that the manpower of construction has to have the Certificate of Expertise (SKA) and Working Skill (SKTK). The purpose is in order that the business of construction service in Indonesia becomes firm, reliable, has high competiveness and produces a high quality construction work. But there is still lot of manpower of construction that has not has it. This research has purpose to find out the factors that influence the manpower of construction on contractor in Badung Regency to have SKA/SKTK. Sample to be researched is the manpower of construction at the contractor of project manager of Badung Regency Government with qualification grade 2, 3, 4, 5 and 6. Data is obtained by spreading out questionnaire and interview. The data analysis and processing is using the factor analysis. Research result is that there are three factors that are identified to have influenced the manpower of construction to have the SKA/SKTK. These three factors are factor I, II and III. These three factors are formed by fifteen variables. The most dominant factor is the factor I. This factor is formed by seven variables those are it still be able to have job without having the SKA/SKTK, the SKA/SKTK is not fully required on the government’s project, the SKA/SKTK is not yet required on non-government’s project, to already have the SKA/SKTK cannot guarantee that the wage/salary will be increased, to already have the SKA/SKTK cannot guarantee the increasing of career level, to already have the SKA/SKTK cannot guarantee the increasing of expertise/work skill.

The research is motivated by the more selective consumers in choosing a house which impact on changes in market conditions ongoing. Developers should anticipate factors that influence changes in market conditions, such as attitudes and behaviors of consumers in choosing a house. One excample of this condition is development of Sunset Garden area located at Jalan Pura Mertasari Sunset Road, Denpasar, Bali which is this properties are able to attract consumers to buy houses in this area although this price of the house is quite expensive. Therefore, the research was conducted to determine factors that are considered in the selection of residential, consumer attitudes and behavior on the selection of a house and the relationship of consumer characteristics and attributes of products offered in this area. This study used research instruments such as questionnaires to obtain information on the characteristics of respondents and the four components of the attitudes and behavior of the level of confidence, the level of evaluation, the level of normative beliefs and motivation levels. The data analysis technique used is a factor analysis to identify the factors considered in choosing a house, attitudes and behavior analysis with Fishbein method and contingency coefficient analysis to determine the magnitude of the relationship variable product attributes and consumer characteristics. The results of this study indicate the factors that affect the house is 5 (five) factors, they are the location and the legality factors, supporting facilities factors, physical factors, factor values, and environmental factors. Attitudes and behavior are shown in choosing a house on Sunset Garden Zone fall into this category good enough. The results showed that there is a relationship between consumer characteristics and attributes of the product which the consumer's income level has the strongest ties to the variable price of the product.

Research on reinforced concrete structure with and without infill wall has been done by modeling the same structure as open frame (OF) and infilled frame (RDP) to compare in their stiffness, force distribution and dimensional changes. In RDP model, the wall is modeled as equivalent diagonal struts with one, two and three struts. Seven-storey building structure is taken as a reference and structures of 4 and 10 floors are used as comparison. To observe the effect of wall discontinuity at ground level additional 4 models were made for the 7 storey building by removing one, four, six, and all nine walls at ground level (RDP7S3SS1, RDP7S3SS2, RDP7S3SS3, and RDP7S3SS4). For seven-storey model, RDP structures with one, two, and three struts have a comparable lateral stiffness but it tends to increase for model with many struts. Compared to OF, RDP structure with one, two, and three struts have smaller lateral deformation with ratio 0,655; 0,636, and 0,612, respectively. Bending moment, shear and axial in the frame of RDP are also smaller than those of OF with ratio 0,223 and 0,916. RDP model with 3 struts gives better force distribution on the frame compared to the model with single strut. Removing all walls at ground level produce inter storey drift ratio of 4, which is a soft storey phenomenon. On the 4, 7, and 10 storey variation the lateral deformation ratio for RDP and OF are 0,547; 0,612, and 0,581, respectively. The cross sectional area of frame for RDP is as low as 40% compared to that of OF.
