The construction sector still has a low achievement in safety issues. Fatal accident rate in construction is higher than average rate in other industries. Because of it, need some attention to minimize the rate of accident in construction. This research examined the key factors of safety planning in the pre-construction stage, and it was based on the theories of accidents causation having the upstream approach. Some theories were: Constraint-Response Theory (CR); Construction Design Management (CDM), and the Process Protocol (Pp). This research broke down the three theories above (CR; CDM; Pp) into the concept of the key factors of safety planning in pre-construction. Then, the concept was verified by construction practitioners and academician, using Delphi method three rotations. During the verification, from the first to the third round, there were reduction and the addition concept and language appropriateness. The findings of this research were assessment models of maturity safety planning in the pre construction stages. There were two models, the model of "radar chart" or MISAP 1 and the model of "worksheet" or MISAP 2.

The development of anti-earthquake structure planning concept starts from planning structure based on force concept (forced based design), based on performance (performance based design) and develops the theory, which introduces and studies the anti-earthquake structure planning concept, which is based on movement (displacement - based), however, all of these element will return to the benefit principle of the building planning itself that is; instead giving safety value, the building construction also giving the safety for the users as well (user). This research is wished could giving either information about the column safety as a result of earthquake toward the planning structure based on force concept (forced based design), based on performance (performance based design) or introducing the planning structure based on displacement (displacement based design). The column safety as a result of earthquake is observed by the rule of SK. SNI T-15-1991-03 and the MJN Priestlyâ€™s suggestion. The result of this research is analyzing the rule, which is conducted in Indonesia that is SK.SNI.T-15-1991-03 and the MJN Priestlyâ€™s suggestion, which is concluded as follows: (A) the development of anti-earthquake structure planning concept (vibration), need special care especially in Indonesia by notice the politic security and globalization situation, (B) by noticing the rule of SNI, ACIâ€™99 and the MJN Priestlyâ€™s suggestion, there are 4 safety principles toward the column. The principles are as follows: (1) the tips of columns along the (lo) must be confined; (2) the column must be strong toward the friction failure (Vic) and stronger from elastic; (3) the column must be safe toward lateral bending (Sh); and (4) guaranteed structure by the philosophy â€œStrong column weak beamâ€, and (C) supporting the suggestion of Prof.Ir.Priyo Suprobo,MS.Ph.D and Ir.

Genetic algorithms have been used to solve various optimization problems. One of the advantages of genetic algorithms is that they have the ability to solve complex optimization problems in a simple way. By using genetic algorithms, the near global optimum can be achieved easily. Although in the early development, binary coded genetic algorithms are more popular, recently real coded genetic algorithms are widely used to solve engineering problemâ€™s optimization. The advantage of using real coded genetic algorithms is the ability of the crossover operator to explore a larger domain of interest. As a result the use of crossover in real coded genetic algorithms may have a detrimental effect, as it can explore the domain that is very far from the expected domain. In the civil engineering area, most variables are positive. Therefore, it is needed to develop a crossover operator that can produce positive-only offspring. In this paper an asymmetric crossover is proposed to solve this problem. It is shown in the experiments that this crossover has a good performance in achieving optimum results.

This analysis studies about the dynamic response of isotropic slab with the semi rigid type of edge conditions which is solved by the Modified Bolotin Method. The dynamic response mostly depends on the characteristics of the slab and the velocity of the transverse load acting on the slab. This analysis uses 10 km/h, 20 km/h, and 30 km/h as the velocity of the transverse load, and 110 km/h as the comparing velocity. Results show that maximum dynamic responses for each velocity does not always occur on the center of the slab, so the characteristics of the slab may be vary. The dynamic response is closest to maximum when the velocity of the load is 110 km/h because it is closer to the critical velocity of the system which is 112 km/h. This analysis assumed the slab is used for the busâ€™ parking ramp. Thus with the 10 km/h until 30 km/h velocity assumption for parking ramp is still quite safe because the velocity is far below the critical velocity of the system. Also the dynamic response of the system is far lower than the maximum response of slab.

Surge tank in hydro-power generation plant is placed on the transition between conveyance pipe channel and chute pipe. The dimension of surge tank is designed based on water mass oscillation result in minimum hydrodynamic pressure, such that it can determine form, type, and configuration of the tank. The sudden increase in hydrodynamic pressure (positive water hammer) is caused by abrupt decrease in water discharge to the turbine to reduce load to the generator. This positive water hammer is dependent on the discharge and time of closure of the valve. Mathematical equation that describes mass oscillation in the reservoir-pipe channel-surge tank is dynamic and solution can be easily using numerical techniques. This paper demonstrates the water hammer oscillation in a surge tank. The result shares that, 1) when the ratio between surge tank area (As) to the pipe area (AT), As/AT below 5, the maximum increase in water pressure is significant, ii) when the ratio As/AT greater than 5, the increase in water pressure is not significant and tends to have slight differences. Key Words : surge-tank, mass oscillationsPermalink: http://ejournal.undip.ac.id/index.php/mkts/article/view/3916[How to cite: Sangkawati, S., 2005, OsilasiÂ Dalam Tangki Pendatar (Surge - Tank) Akibat Penutupan Turbin Secara Mendadak, Jurnal Media Komunikasi Teknik Sipil, Volume 13, Nomor 2, pp. 122-129]
