Abstract

In a cross-sectional design of reinforced concrete, is generally assumed to be only 30 to 50% higher cross section work withstand being hit withstand tensile rest. From these assumptions and with the use of the model diagram, meaning there are still opportunities to optimize the function of the concrete with the use of lower levels of the cement mixture. With this method the benefits expected to be obtained and optimally efficient use of cement as an adhesive in the construction of reinforced concrete. Experiments carried out by varying the mix proportion of concrete as high as 50% higher for the cross-sectional area that will receive the attractive force. Of the six variations resulting mixture is made that the flexural strength of concrete as indicated by the flexural strength test results obtained that the bending moment variation cement mix with lower levels do not affect the flexural strength of about 9.2 KNm.

Abstract

This research was conducted to analyse the alternative which might be done to givesolution for column structure reinforcement and bar in case of building room layoutchange. There were 4 methods which were presented for analysing column structurereinforcement and bar in this research. The dimensions of the removed column were25x40 cm with a length of 350 cm and the reinforced beams were 25x40 cm withspan length of 800 cm. This research also showed the price which was gotten fromvarious methods did as consideration of solution chosen. The analysis wasconducted by using SAP2000 application. This analysis was done by 2 columnremoval without reinforcement which in the fact the structure is not powerful if thereis not any reinforcement by the result of 2 column removal so that for safetyanticipation, it is better if reinforcement is implemented. The first method is themethod with the elimination of 2 columns but without the reinforced structure, afterSAP2000 analysis on the portal, obtained the maximum moment that happened was76,1 KN exceeding the permitted moments of 62 KN so that this will be dangerous tothe strength of the structure, therefore for security anticipation should be donereinforcement. The second method which is the first solution is the method ofJacketing Column & Beam obtained the result that the building was considered safeby enlarging the original beam dimensions 25x40 cm to 35x65 cm and the originalcolumns 25x30 cm to 40x40 cm. It is also supported by the value of the momentsshown not exceeding the maximum allowed moments. The third method is analternative to the second retrofit solution by providing additional structuralelements instead of the existing missing columns, but with this method it willinterfere with the aesthetic value of the building, since the new element beams arevery visible. The last method is the use of CFRP (Carbon Fiber ReinforcedPolymer), this method proved to be the most efficient way to overcome the structuralreinforcement problems at As-Shohabat mosque in terms of processing time, laborcost, and sufficient strength to replace the reinforcement that occurs due to thereduction of the column that supports the block.Kata kunci: strengthening column and beam, strengthening structure, CFRP

Abstract

Natural rivers are characterized by a meandering channel with multiple grain-size bed and unsteady flow. Among some of the properties of the sediment grains, the size of the sediment is one of nature's most important and widely used in sedimentation engineering. Grain size greatly affects the easy presence and extent of sediment transported. To study the characteristics of bed material on the sediment transport, various studies have been conducted. This paper examines statistical parameters of grain on the sediment transport from a natural river (River Krasak, Yogyakarta). Variables studied include the classification of grain size, mean (average), standard deviation (sorting), skewness, and kurtosis. Based on the statistical parameters of grain size, the results from three stations showed that bed materials of Krasak 1 are characterized by gravel mode, very poorly sorted, and distributed platikurtic negative skewness. Types of samples are polymodal. Bed materials of Krasak 2 are characterized by the mode of sand, and poorly sorted, and distributed platikurtic very positive skewness. Type of samples are bimodal. While the bed material of Krasak 3 are characterized by sand mode and poorly sorted, and distributed platikurtic very positive skewness. Types of samples are polymodal

Abstract

Land around building of Materials and Land Laboratory of Civil Engineering Department of Semarang State Polytechnic infrastructure such as roads (asphalt, concrete, paving blocks) and drains an area with impermeable pavement that can not absorb water. Impact when the rainy season occurs puddle on a large scale into the flood, instead of the drought in the dry season due to lack of availability of ground water. To overcome this, the seepage of rain made using the method Biopori Hole Infiltration (LRB). Infiltration pits Biopori a cylindrical hole about 10 cm in diameter is dug into the ground. Depth does not exceed the groundwater table, which is about 100 cm of the soil surface. The hole is filled to the brim organic waste closer to the ground. LRB can increase the ability of soil to absorb water. The water absorption wells that penetrate through the surface of the wall into the soil around the hole LRB. Thus, it will increase the water reserves in the soil. Biopori soil moisture content and moisture content of 85.342% 35.168% native soil. So the water content in the soil biopori greater than the water content in the original soil. Infiltration load will increase in line with increasing hole diameter Biopori infiltration. LRB diameter of 10 cm with a depth of 100 cm using only horizontal surface 79 cm2 produces vertical surface area of 0.314 m2 wall hole, then expand the soil surface can be 40 times the direct contact with the compost. The volume of incoming waste deposited in the pit will reach a maximum of 7.9 liters biodervitas ground through the wall hole, will cause maximum load 25 liter/m2 composting. Land use will affect the power of absorbing soil against rain water. On the ground that a lot of concrete and sealed in a rather dense residential, small power of absorbing soil. This is very different from the conditions in the yard or garden soil that has a power of absorbing up to 100%. Therefore, in the densely populated area needed more LRB to increase the power of absorbing soil.

Abstract

Fly ash and bottom ash are solid waste generated by coal combustion in steam power plants or other industrial processes. This solid waste is present in a relatively large amount, requiring serious management to avoid causing environmental pollution problems, such as air pollution, waters and other ecosystem degradation. The phenomenon that occurs, the handling of this waste is not maximal, it is proven that there are still companies dumping coal ash in the Southern Ring Road of Salatiga city (Suara Merdeka, 2012), coal waste feeding victims at Kayen Pati (Sura Merdeka, 2012), events like this show That the solid waste management from industry is not well managed. While research in the field of Materials Engineering has been done by researchers as an effort to solve problems and utilize this industrial waste to be produced into other industries such as building materials. The results showed that the quality of Concrete with model / type B10 s.d. B17.5 there is an increase in average compressive strength. Hightst increase in fly ash and bottom ash 12.5% with average compressive strength reaching 36.09 N / mm² age of 3 days, while decrease occurred in addition of fly ash and bottom ash to 20% with decrease of compressive strength of lowest average 28.03 N / mm² at 28 day test age. The regression equation obtained Y = - 0,181 X² - 2,367 X + 24,50 with correlation value R² = 0,886, it means with addition of fly ash and bottom ash have very strong influence to compressive strength of concrete. So we get an illustration that by adding fly ash and bottom ash on the manufa ture of concrete and the quality of concrete to be better.Kata Kunci: fly ash and bottom ash, pollution, concrete

Abstract

The porous asphalt mixture is a new generation of flexible pavement that is able to pass water in the upper layer (wearing course) both vertically and horizontally. The porous asphalt layer effectively provides more safety, especially when it rains to avoid aquaplaning which causes roughness of the surface to be more rough. Therefore, at this time there are many studies on the use of alternative materials to replace the limited natural materials with materials that can be utilized. The results showed that porous asphalt mixture with used tire crumb as a fine aggregate mixture had an increase in flow value of 6.32% with a decrease in stability value by 27.52% and a decrease Marshall Quotient value at 31.82%. The testing of roughness is increased by 17.71% and Mu-Meter 24.14%. This research is effective in overcoming environmental problems which include processing tire waste of 3.03 tons for 1 km of road pavement construction work.

Abstract

Retaining wall is one of the reinforcing techniques used to control soil movement. Reinforcement with retaining walls is relatively expensive so an efficient design is needed. Unfortunately, the guidelines for planning a retaining wall are limited. Analysis of design criteria was carried out on silt clay soil taken in the area of the Karang Joang Kalimantan Institute of Technology (ITK) area based on the dimension guide given by Hardiyatmo (2010) and Nakazawa, et al (1980) for safe slope height based on the type of retaining wall. The minimum criteria for cantilever type retaining walls with a slope height of 2-3 meters is the width of the TOE (A) = B / 3 meters, the base width retaining wall (B) = minimum of 0.7 H meters, the width of the upper wall (C) = 0.2 meters and wall thickness (D) = H / 10-H / 12 meters, while for slopes with a height of 4- 5 meters the safe dimension range is TOE (A) width = A / 3, slope width (B) is designed to be a minimum of 0.9 H meters, width of the wall (C) = minimum 0.2 meters and wall thickness (D) = H / 10-H / 12 meters. Gravity retaining wall has design criteria for slopes as high as 2-3 meters of A = D / 2-D meters, B is taken to a minimum of 0.7 H meters, a minimum C value of 0.3 m and D of H / 8 - H / 6 meters for slopes with a height of 2-3 meters, meanwhile for slopes with a height of 4-5 meters, B to a minimum of 0.9 H meters, with a value of A = D / 2-D meters, the C value is designed to be a minimum of 0.3 meters and D = H / 8 - H / 6 meters.

Abstract

The foundation layers of road construction in general have many problems of land subsidence. Land subsidence does not occur only on the ground or the original soil. Decrease of soil may also occur on pile or soil. Less than optimal density of the soil or the choice of unsuitable heap material may be the cause of the land subsidence in the embankment. Land subsidence also occurred in the National Road Development Project Segment Giriwoyo-Duwet, Wonogiri, Central Java, Indonesia, causing a decrease in road elevation from planned elevations. Decreasing this elevation can cause the standards of the cleverness and comfort of the road not being met. This study explains the results of the analysis of the large decrease in soil that occurred. The analysis is done by two methods. The method is done by theoretical calculation and by analysis using plaxis software. The results of the analysis show that the characteristics of soil used as soil pile material is silt soil with high and soft plasticity characteristics. The analysis also illustrates the factors of land degradation due to poor soil characteristics, carrying capacity and soil density less than standard and weather factors. The magnitude of the decline that occurred showed a decrease of 3-7 cm from the observation on the location, 1,1 cm from the results of plaxis software analysis and 1,7 cm from theoretical calculations.
