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.

Abstract

At present, plastic is a material that is needed by the community at large, where the impact is also very extraordinary after the plastic is used in everyday life which can cause serious problems if the management is not done properly. The problem of plastic waste does not only occur in the city of Semarang, but also in other cities, so that the Ministry of Environment and Forestry has implemented a paid plastic bag program in the short term. But this is only to deal with problems in the short term. In the long run, it will not solve the problem of "plastic waste", because the policy actually encourages people to buy plastic which, of course, will add a new burden for the community to buy it. Based on the above problems, it is necessary to utilize this plastic waste to be made into road pavement materials such as in the manufacture of Asphal Concrette Wearing Course, by making 5 mixed variations ranging from (2 to 10)% of the weight of the aggregate . This research was initiated through a survey process, material procurement, testing of stacking materials, making test specimens, testing specimens. The results of the research can show that the type of Thermosetting plastic waste has a significant influence on the Asphalt Concrete mixture AC-WC heat mixture, including: Density, Marshall Stability, Flow, VIM, VMA, MQ and the remaining Marshall Stability tend to show an increase, moderate VFA and VIMrefusal Density values tend to show a decrease. Thus the plastic waste from the Thermosetting type can be used as a partial replacement of the aggregate for the Asphalt Concrete mixture AC-WC heat mixture with a plastic waste content is limited to a maximum of 10% and at an optimum asphalt content of 5.55%. Thus this research is expected to be of benefit to the industry and the people of Semarang in relation to the use of plastic waste for road pavement.

Abstract

Value engineering (rekayasa nilai) menurut Chandra (1986) adalah suatu usaha yang terorganisir untuk menganalisis suatu permasalahan yang bertujuan untuk mencapai fungsi-fungsi yang dikehendaki dengan biaya total dan hasil akhir yang optimal. Value engineering dipengaruhi beberapa aspek, diantaranya dilihat dari segi bahan, cara pengerjaan, jumlah tenaga kerja, waktu pelaksanaan, dan lain-lain. Hal ini bertujuan untuk mengoptimalisasi dengan cara pengefisienan anggaran biaya kembali agar mendapatkan anggaran yang paling hemat. Sehingga dari hal tersebut penulis melaksanakan value engineering pada Proyek Rumah Sakit Onkologi Kotabaru Yogyakarta. Kondisi proyek sekerang ini pada pekerjaan struktur bawah, kondisi perencanaan sebelumnya gedung di rencakan 3 lantai tetapi pada pekerjaan konstruksinya hanya 2 lantai. Atas alasan kekurangan ruang pada perjalanan konstruksi pemilik meminta untuk konstruksi menjadi 3 lantai. Dari kondisi tersebut penulis melaksanakan value engineering untuk mengoptimalkan desain struktur agar mendapat alternatif paling hemat. Value engineering pada proyek ini menggunakan metode zero-one dengan 2 alternatif pilihan yaitu merubah desain kolom,balok dan tetap menggunakan desain plat eksisting sebagai alternatif 1 dan merubah desain kolom,balok dan merubah material menjadi alternatif 2. Dari itu di dapatkan Penghematan untuk alternatif 1 Rp. 131.675.000-, dan untuk alternatif 2 Rp. 267.053.000-,Pada perhitungan dengan metode zero-one alternatif terbaik yaitu alternatif 2 dengan bobot 55,55% dan bobot alternatif 1 adalah 44,45%.

Abstract

The Jenderal Sudirman area has a strategic function as a trade and service area that gives strong character in the Salatiga. The growth of trade and service activities has increased to become a regional trading area that is influenced by modern trade. With the existence of modern shopping centers, five-star hotels, banking services beside the existing traditional markets affect the increasement of activities. The high intensity of activities raises problems related to traffic congestion. The purpose of this research is to determine the performance of the road network in the Jenderal Sudirman area and formulate a traffic management strategy to deal with the current traffic problems. This research was conducted by analyzing the existing conditions. The method of calculating volume, degree of saturation, and speed used is MKJI 1997. This study uses the SATURN 10.4 program to determine overall network performance. The results showed that the existing condition of the Jenderal Sudirman area undergone problems in Jalan Jenderal Sudirman (2 directions) with 0.86 degree of saturation. The first scenario analysis shows the value of the degree of saturation in Jalan Jenderal Sudirman dropped to 0.55; The Second scenario analysis to 0.90; and the third scenario analysis becomes 0.98. As for the overall network performance, first scenario has advantages on 3 indicators, namely average speed, passenger car unit(pcu)-hour, pcu-rupiah. Based on the overall analysis, a concept of handling traffic problems can be arranged by applying the traffic management strategy first scenario and second scenario through the short-term and long-term stages.
