Abstract

Semarang is one of the cities that most of its territory is always inundated by tidal water, especially in areas near to the beach. Most of the houses in these areas often take in rob water, so the house becomes less healthy and less comfortable. Therefore we want to make a home stage floor can be raised with the increase in tidal water using a jacking system, which we call the stage house floor lifting method. The success of the house lifting depends on the model of the main beams and columns and its connection.Therefore we try to overcome the problem by doing research with the aims: (a) Planning main column model (b). Planning main beam model (c). Planning the main beam - column connection system. Methode research done by making several alternative column model, beam and joint and then tested in the laboratory, which is then compared with the real burden for small home (<30m2). Outcomes of this research are (a). The column used is made of reinforced concrete with a hole interval of 20 cm. (b). The beam used are profile IWF 15. (c). Connection beam and column using 4 bolts 12 mm.

Abstract

Public infrastructure that supports mobility is closely related to the issue of sustainability. Research on pedestrian facilities at the university is a description of the extent to which pedestrian is used in Indonesia. The purpose of this research is to identify the pedestrian facilities, compare the availability of pedestrian facilities and to know the perception of the academic community from the case study of Diponegoro University Campus and Semarang State University. The research method used is case study with qualitative approach based on assessment of nine criteria of sustainable pedestrian. The comfortable and safe pedestrian conditions in the Undip Campus are the most powerful aspects of the correlation among the nine aspects that are compared. While in Unnes Campus, the feasibility of pedestrian and its easy to reach correlation is very strong against the level of satisfaction of respondents to Pedestrian infrastructure that exist today. The connectivity of pedestrian in Undip Campus is higher than in Unnes Campus, and it turns out that in other technical aspects it tends to be so. The similarity of the two campus locations that still do not meet the requirements of satisfaction is the use of pedestrian by the difable (with special needs). Based on the assessment of sampling point (59 points) from the pedestrian on the Undip and Unnes campuses, in general the two research sites have not fully implemented 9 sustainable pedestrian criteria. The need for pedestrian data collection and arrangement as part of the sustainable Campus development becomes the need of campus managers in the futureKata kunci : Pedestrian, sustainable, campus

Abstract

The release of ceramics is an undesirable event, one of the causes is the presence of trapped air which causes the area attached to the wall to decrease. To reduce this, additional ingredients / smaller silica fume additives (<1μm) can be used to fill the hollow part. The purpose of this study was to measure and compare the properties of ceramic adhesives with and without the addition of silica fume to ceramic adhesives, and to determine the percentage of addition of silica fume to obtain the most optimal adhesive strength. The method used is an experimental method in the laboratory by conducting tests of ceramic adhesion based on ASTM C 482-02 and SNI 03-4877-1998. The level of addition of silica fume used is 5, 10, 15, and 20% of the weight of cement. The test results show that there is a "very strong" relationship between the addition of silica fume and ceramic adhesive properties in increasing the strength of the adhesive power as evidenced by correlation analysis with an R2 value of 0.9042. The strength of the adhesive power of ceramics without silica fume as a control variable is 1.4146 MPa, while the strength with a mixture of silica fume is 1.8051 MPa, 1.9606 MPa, 1.8811 MPa, and 1.5666 MPa, respectively. The regression analysis showed that the highest / optimum strength was achieved when the proportion of silica fume addition was 10.8% of the weight of cement with a sticky power strength value of 1.9637 MPa or an increase of 38.82% on the control variable which did not use the added silica fume material.Kata kunci: Sifat adhesif keramik, daya rekat keramik, silica fume.
