It is found that the pelletizer method by using mixer without blade is one possibility to manufacture artificial aggregates. The optimum mixture composition of artificial aggregate is found to be 3 BA : 1FA : 0,5 C , by weight, and immersed once in cement slurry. The water content in ssd condition is 27% with the compressive strength of the aggregate 2.4 MPa on the seventh day. Concrete produced with mixture compositition of 1 cement : 1.5 sand by weight, resulted in water content of 14.63% in ssd condition and compresive strength of 14.20 MPa at 28th day.","PeriodicalId":187066,"journal":{"name":"Dimensi Utama Teknik Sipil","volume":"436 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133377039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Room acoustic performance can be achieved if some room acoustic objective parameters are taken into account, such as background noise level, reverberation time, and sound coverage. In order to meet these parameters, it can be done by using materials with appropriate coefficient absorbstion on floor, wall, ceiling and room geometry. Room acoustic objective parameters should be considered in design phase for optimum benefit. Room acoustic simulation on the design of multipurpose hall P1 and P2 Petra Christian University will be done by computer simulation.

Performance of the organization requires trust that each individual, team, or group can act achieve the desired goal. The level of trust in an organization is influenced by the organizational culture. This study aims to determine the organizational culture and the level of confidence in large and medium-sized construction company in Surabaya, as well as the relationship between the level of trust and organizational culture.Based on the research that has been done, large and medium-sized contraction company in Surabaya tend to Clan culture type than other type of culture (Adhocracy, Market, and Hierarchy), which is concerned with loyalty and tradition; with high degree of organization trust in contractor company. Organizational culture is positively correlated with the level of trust, making any type of organizational culture as an important asset for the company to increase trust in the contractor organization, and the Hierarchy culture that can be used as the primary reference organization in increasing trust.","PeriodicalId":187066,"journal":{"name":"Dimensi Utama Teknik Sipil","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115170737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Green Building Council Indonesia (GBCI) is the institution that organizes the green building certification in Indonesia. The view from construction parties is needed to understand the level of interest and level of implementation of green building parameters and the impact of green building parameters on project life cycle time. This research carried out by distributing questionnaires to construction parties in Jakarta and Surabaya. Descriptive analysis and Structural Equation Modelling is used to understand the respondent views of the green building parameters and the impact of green building parameters on project life cycle time.The results showed that the level of interest of green building parameters is high. The comparison between level of importance and level of implementation shows that the implementation rate is lower than the importance rate. Water conservation is a significant aspect affecting the project life cycle time specifically the design stage, while the other aspects haven’t been significantly affecting project life cycle time.
