Abstract

Road development in Indonesia in average needs 1,2 million ton of asphalt. 600 thousand ton fromthat amount supplied by Pertamina and the rest has been imported from various countries. The volume of imported asphalt which nearby 50% of national need, of course, give a negative impact to Indonesia. Because of that, a continuity optimalization effort for using asbuton has been kept. Since asbuton invented, the technology of using asbuton keep evolutes from conventional asbuton. fine asbuton, micro asbuton, asbuton mastic. granulated asbuton and pure asbuton. The use of granulated asbuton have conducted on project scale in five provinces in Indonesia and concluded that technically asphaltic asbuton mixture could be produced and applicated in field and the mixture shown better performance compared to conventional asphaltic mixture. Not only the choice of asphaltic mixtures type is not depend solely on technical reason, but also economic reason. The aim of this study is to know the economy feasibility of using granulated asbuton in asphaltic mixture in Middle Borneo. This study concluded that the use of granulated asbuton as a pavement materials gave a positive effect on economic aspect, as it reduced the use of refinery asphalt and aggregate. In its optimum dozes, the price of AC-WC contained asbuton in type of B5/20 and B15/20 is economically feasible compared to AC-WC without asbuton with the same thickness when maximum ratio of asbuton price is 0.2 of refinery asphalt. And for Bl5/25 and B20/25 asbuton types, the maximum ratio is 0.25. For the same service life, asbuton type of B5/20 is economically feasible when its maximum price ratio to refinery asphalt is 0.5. And for Bl5/20, Bl5/25 and B20/25 type of asbuton its maximum ratio are 0.4.

Abstract

Landslides is estimated to increase in the future as the impact of climate change, especially in changing of precipitation patterns, both of intensity and duration. Landslides are influenced by the rainfall duration that has a long duration and in infiltration capacity. The effect of infiltration of ground water causes volumetric water content increases and groundwater table recharge, which converts unsaturated soils become saturated soil. The longer infiltration causes soil cohesion decrease which is an indication of soil strenght decrease. It can be described by the relationship between the IDF(Intensity-Duration Frequency) curve, Hydraulic Conductivity curve, Soil Water Characteristic curve of slope stability analysis. This research will model the slope stability conditions at baseline (condition 30 years back) and when the projection (condition 30 years future) using the program SLOPE/w.

Abstract

Ground improvement techniques are commonly performed on peat soil is improved physically using geosynthetic materials. The often used is geotextile. In this study the use of geotextile replaced with the use of a tarpaulin and bamboo grid. They are used as reinforcement materials that is expected to be an alternative to increase the bearing capacity of peat soil which is used as the based of shallow foundation. The aim of this study is to determine the increase in the bearing capacity of variation in depth of reinforcement to the base foundation (0,25B; 0,5B; 1B) and variation in width of reinforcement (2B, 3B, 4B) to the value of bearing capacity withouth reinforcement. The research methodologies used is laboratory-testing. The data obtained from these tests were analyzed by comparing the value of bearing capacity between unreinforced soils and reinfoces soils reffered as Bearing Capacity Ratio (BCR). The results showed that the variation in the depth of the tarpaulin and bamboo on the basic foundation of the grid did not always show a rise greater carrying capacity , however, wide variations in accretion reinforcement always indicates an increase in the carrying capacity of the land. In the distance variation of reinforcement to the foundation, the maximum increase is shown at a depth of 0,5 B with a width of reinforcement for the 4B qu at 20,44 kPa. The largest value of BCR is variation in depth of reinforcement to the base foundation 0,5 B and variation in width of reinforcement 4B with a value of 3,78 and a percent increase of 277,8 %.

Abstract

The city of Semarang can generally be divided into two regions. The first is the upper region with hilly soil condition, solid and the height almost reaches 350 meters from the sea level.The second is the lower region which is softly grained alluvial plains. The position of the lower land of Semarang has same height with the sea level, so that is too risky when the water overflows onto mainland. The issues that arise, are the soil becomes land subsidence because additional load onto it, consolidation and the excessive groundwater so when tides has come through mainland and flood some territory of the lower land of Semarang. The purpose of this research is to create a map of puddle, because of land subsidence that has made “rob” (Java Slang) and extensive changes puddle from time to time. That results will make stakeholders to adjust the existing condition. The methodology of research is done by drilling machine on 5 points until 30 meters depth to get soils sample that spreads in the at whole of the lower land of Semarang. The sample has been obtained and also tested by using the mechanical properties and soil properties at UNISSULA’s soil mechanical laboratory. Based on the test lab,it is analyzed to get the result how deep the soil settlement caused due to consolidation. Finally it holds analyzing extensive changes puddle cause of land subsidence by using GIS. The result of this research is puddles map in Semarang city and it changes from time to time. Besides that the analysis is further to the north (seaward) down more, but the time also give the biggest impact of land subsidence.

Abstract

Analisis keseimbangan air dilakukan pada embung Universitas Sriwijaya untuk mengetahui keseimbangan air ketika dilengkapi dengan spillway pada saluran outflow. Analisis yang dilakukan meliputi analisis debit air yang masuk ke dalam embung, analisis pengisian embung, analisis debit banjir rencana, dan analisis tinggi muka air di atas spillway. Untuk debit air yang keluar dari saluran outflow, jika elevasi tinggi muka air melebihi spillway maka terjadi debit outflow. Debit air yang masuk ke dalam embung hanya bersumber dari saluran inflow yang terdapat pada embung, sedangkan debit air masuk dari Sungai Kelekar tidak diperhitungkan. Perhitungan volume untuk kebutuhan air tidak termasuk dalam variabel yang mempengaruhi keseimbangan air pada embung. Sedangkan debit banjir rencana yang digunakan adalah periode ulang 50 tahun. Data yang digunakan meliputi data profil embung, catchment area embung, data curah hujan, data klimatologi, dan data infiltrasi. Berdasarkan hasil analisis pengisian embung didapatkan nilai debit air rata-rata yang mengisi embung yaitu 343.859,14 m3/bulan. Nilai ΔS terbesar terjadi pada Bulan Desember dengan nilai 686.610 m3/bulan, sedangkan Nilai ΔS terendah terjadi pada Bulan Juli dengan nilai 2.829,6 m3/bulan. Berdasarkan analisis Debit banjir dengan periode ulang 50 tahun, didapatkan total debit banjir periode ulang 50 tahun dari saluran inflow yang masuk ke dalam embung Universitas Sriwijaya adalah sebesar 44,11 m3/det. Berdasarkan hasil analisis ketinggian muka air di atas spillway saat terjadi banjir periode ulang 50 tahun didapatkan ketinggian muka air di atas spillway sebesar 1,71 meter, Sehingga ketinggian dari dasar spillway hingga muka air adalah sebesar 3,71 meter < 5,5 meter. Maka tidak terjadi luapan atau banjir dari dalam embung Universitas Sriwijaya. Berdasarkan hasil analisis keseimbangan air pada embung Universitas Sriwijaya didapatkan kesimpulan bahwa jika embung tersebut dilengkapi dengan bangunan pelimpah (spillway) maka tidak akan terjadi kekeringan pada embung, hal ini dapat diketahui dari hasil analisis pengisian embung yang menunjukan bahwa tidak terjadi nilai 0 atau minus pada nilai debit air yang tersedia pada embung (ΔS).
