Abstract

In addition to the construction of an alternative form of water reservoirs, to tackle the problem at the Weirs Karangtalun can also be by way of construction of the barrage. The reason for the need for the construction of the dam movement emerged based on the survey results, which show that Karangtalun weir downstream conditions are now damaged due deggredasi riverbed downstream. Weir crest had already suffered some damage due to collision damage to the stone. It is feared that one day the dam will collapse.Barrage to capture the motion of the water to drain Progo river can be more time in the count because of the barrage that comes w ith taking the doors and door rinse. raw water needs in the catchemet area Progo 2 of irrigation kalibawang and mataram, flood discharge plan is designed with 100-year return period of 1157 m3/sec.Barrage height of 10 m. Weir is equipped with radial main door, stilling basin using the threshold type width of 35 m. Construction of barrage to cost about 222 billion and a plan of implementation 40 weeks.

Abstract

Highway pavement in Indonesia generally use a mix asphalt concrete as a surface layer consisting of a mixture of constituent materials coarse aggregate, fine aggregate, filler and bitumen. HRS is a mixture suitable for use in tropical areas like Indonesia because it has high elasticity and resistance to fatigue plastic (Rantetoding, 1984). HRS mixture consists of coarse aggregate, fine and asphalt. Fine aggregate form filler, which is necessary to fill voids between the aggregate particles so as to increase the density of the mixture. In general filler used is stone ash, stone ash filler but is relatively expensive, so it is necessary to find other alternatives to the use of cheaper materials for filler substitutes standard. One of the waste materials that can be used is the waste from sugar mills bagasse. Refiners produce waste in the form of bagasse, the percentage content of chemical compounds (Silica) on bagasse ash was 70.94% which is expected to improve the quality of asphalt mix. The purpose of this research is to determine the performance of asphalt concrete type of HRS-WC when using bagasse ash filler compared with stone ash filler, with the goal of getting an alternative filler in the form of bagasse ash. Test characteristics of aggregate, filler and bitumen done before making Marshall specimens to determine whether the materialis qualified or not as asphalt mix material. This study refers to the Spesifikasi Umum Bina Marga 2010, of the Directorate General of Highways. The results showed the test aggregate, filler and bitumen, as well as all the HRS-WC mixed with bagasse ash filler and stones ash filler qualify. The use of bagasse ash filler mixed with HRS-WC increasing bitumen content is 6.95%, resulting in values, VIM: 5.96%, VMA: 21:36% and VFB: 72.12%, is higher than the HRS-WC mixture using stones ash filler that is 6.75%, with a value of VIM: 5.95%, VMA: 20.64% and VFB: 71.68%. In addition to the value of bagasse ash filler Stability: 1231.07 Kg, Marshall Quotient: 260.58 Kg / mm and flow: 4.72 mm being lower than the value of Stability: 1280.98 Kg, Marshall Quotient: 268.97 Kg / mm and flow: 4.76 mm in stone ash filler. This suggests that the HRS-WC mixture using bagasse ash filler bitumen requires more than the HRS-WC mixture using stone ash filler. From the results of this analysis indicate that the use of bagasse ash filler mixed with HRS-WC to qualify as an alternative filler materials stone ash, so that the bagasse ash can be used for asphalt concrete mix HRS-WC, in which the results are not much different from mixed HRS-WC using stone ash filler.

Abstract

Road maintenance and rehabilitation program is a program to improve functional condition of a road pavement. EVERSERIES 5.0 is a group of programs having an ability to do a complex analysis especially in determining pavement respond and modulus, and also designing pavement overlay, i.e. EVERSTRESS, EVERCALC and EVERPAVE, respectively.The objective of this research was to evaluate Bina Marga Pd T-05-2005-B Guideline in designing overlay thickness by comparing the guideline with EVERSERIES program. The location of the study was TMII – Cibubur segment of Jagorawi toll road. For the purpose of the research, two-way (direction A and B) deflection data along the segment together with 5-year traffic volume data were collected. In determining overlay thickness, EVERSERIES program firstly evaluated the existing deflection and pavement temperature data and used them in backcalculation process to produce elastic moduli. The moduli, together with traffic volume data, then were used to calculate the overlay thickness.On the other hand, Bina Marga Guideline calculated manually the overlay thickness based on the category of deflections. The results showed that Bina Marga Guidelines always produced less thickness than EVERSERIES program, i.e. 7.2 and 7.12 cm for direction A and B, respectively, compared with thicknesses produced by EVERSERIES, that is, 11.9 and 10.29 cm for direction A and B, respectively. This is because there is a difference in overview of pavement-layer distress between the two methods.

Abstract

Drainage system with retention pond and pumping station is the most effective and efficient system to manage flood in drainage area. Semarang River catchment area has became one of important area in Semarang, because it ends near Tanjung Mas Port, that is basically one of central business district in Semarang, so that the flood which inundate that area become major problem for local government. Retention pond and pumping station drainage system are designed using 10 year return period flood discharge. From the result of 10 year recurrence interval rainfall data processing by using Nakyasu method, thus can be obtained Q design = 63,983 m3/sec, that  will be used to design drainage channel. By comparing existing drainage channel and designed drainage channel, it’s obtained that drainage channel in M.H. Thamrin Street and Gajah Mada Street need to be replaced, because they can’t intercept and retain flood discharge. By using flood routing method with 10 year recurrence interval Q, it can be obtained the area of retention pond  is 68.000m2 and 88.400m3 with  8  pumps in total with 5 m3/sec capacity for each pump.

Abstract

Semarang roads - Kendal, which is part of the North Coast, an arterial road linking central basis of national economic activity. With the increased traffic on North Coast Road, and included on this road, especially with the presence of a growing number of trucks that are overweight  overloaded on this road, so for the next few years is expected to be down this path of service, either in terms of traffic performance and the performance of the pavement. Given these problems, this study is conducted to evaluate the performance of road traffic Semarang - Kendal and estimate the need for the added layer of the existing pavement as a result of overloading (overloading) is. For purposes of analysis, the method used in this research capacity (MKJI) to analyze traffic performance, and methods of Highways 2002 to analyze the needs of additional layers as a result of overloading. From the results of the analysis, found that the value of the performance of the traffic for the roads to be reviewed on line Semarang - Kendal, the value of DS = 0.74 in 2019, while in the opposite lane (Kendal - Semarang) DS values obtained larger is equal to 0.79; thus advisable to increase the geometric path (such as road widening) or by shifting part of the burden to the rail mode as a solution to improve traffic performance in the coming years. As for the analysis of the existing pavement, this study used two types of load, which is ideal load (with reference to the amount of the allowable load or JBI) and actual load (of the survey). The analysis showed that in the year 2019 plan, the road Semarang - Kendal takes a thick layer added by 6 cm (for ideal weight) and 10 cm (for actual expenses). If the residual life analysis, then by applying the actual load on the existing pavement was found that the existing pavement structure can only support the weight overload for 4 years and 2 months of age 10-year plan.

Abstract

This research aimed at investigating the effect of glass thickness on the strength of annealed glass panels. The research was conducted using both experimental tests and numerical simulations. The experimental tests were conducted using the double ring method, while the numerical simulations were carried out using Finite Element Method (FEM). Numerical simulations were conducted first to determine efficient meshing, dimension of the specimen, and the equipment capacity. The number of specimens were 400 with the same width and length of 200 mm x 200 mm. The thickness of which were varied from 3 mm up to 10 mm. The test results were maximum load and fracture origin. Both of these results were used to calculate the strength of the glass that was expressed as failure stress at the location of fracture origin. The failure stress scattered in a wide range, hence statistical analysis was required to analyze the glass strength. From the analysis, it can be seen that the strength of glass was affected by its thickness. Some graphs have been created to show the allowable pressure that can be resisted by certain dimension of glass panels.
