PENGARUH PERKEMBANGAN PEMBANGUNAN INFRASTRUKTUR JALAN TERHADAP PERTUMBUHAN PEMANFAATAN LAHAN KOTA
Full text linkThe road infrastructure has a significant influence on the development facilities of the city as acenter of a new generation. Bandar Lampung as the capital of Lampung province was not im -mune to these problems. Development of a very dynamic with a diverse urban population, trig-gered over the land due to the complexity of the construction of roads that will lead to many nega-tive issues in the future. Problem caused by the increasing development of road infrastructure inand on the outskirts of the city, will increase the rate of population growth to the high impact ofurban land usage that is not in line with the regional spatial plan. To suppress the effect of infra-structure development on land conversion, required policy analysis tool. The making of policysimulation modeling of land usage on the development of road infrastructure using dynamic sys-tem modeling. The models created using causality approach (causal loop), starting from the basicmodeling that is a mapping of the real system of urban land usage which is then converted into 4model. Model of transportation, demography, population and land usage activities, which are as-sociated with a causal relationship. The models will be aided by the GIS as spatial data analysisinput, the models simulate some policy scenarios. The most optimal scenario results to reducingthe rate of population growth, reduce the level of unemployment, increased GDP, and control thepattern of land usage. By performing simulations using these scenarios, all the desired purposecan be met and brought a good impact on the growth of Bandar Lampung city
POTENSI BAHAYA GEMPA DAN ANALISIS REGANGAN DI SELAT SUNDA BERBASIS GPS (GLOBAL POSITIONING SYSTEM)
No full textThe Sunda Strait is the meeting of two tectonic plates, the Eurasian plate and Indo-Australianplate. Sunda Strait has a fairly high seismic activity. This is shown by several earthquakes thathave occurred in the Sunda Strait. The high seismic activity was caused by the presence of activefaults and subduction zones in the Sunda Strait. Based on the fairly high seismic activity in theSunda Strait is necessary to do research on the strain rate that occurred in the Sunda Strait.In thisstudy CGPS observations contained in the Sunda Strait and parts of Java Barat. Based on theresults of GPS data processing, the observation point in the western part of the Sunda Strait hasvelocity in the direction of the North West with a value ranging from 2.21 to 3.16 shift in cm / yearand the eastern part of the Sunda Strait between 2.09 to 3.24 shift cm / year to the Northeast.Based on the pattern of strain, the West tends to have an extension of the Sunda Strait, as well asfor the eastern Sunda Strait. While the northern part of the Sunda Strait compressed. This showsthe activity and the Sumatran Subduction Fault in the area

Full text linkImplementation of air traffic safety is shown from good operation and free from activity which against the law. This statement has declared on Government Regulation about Air Traffic Safety in Indonesia. Analysis of Pavement Classification Number (PCN) value is the one of air traffic safety requirement. Due to that statement, this research try to evaluation and analysis about performance of runway based on analytical method and theoritical method using data from HWD (Heavy Weight Deflectometer) test. The result of performance runway will shown on PCN value.HWD tests are routinely conducted at the FAA to evaluate performance of pavemnet. HWD tests are conducted in two phases.In the first phase, HWD geophone sensors record vertical deflections at seven points on thepavement surface. The collected data are used for pavement evaluation and environment related thickness response analysis. In the second phase, the insitu pavement sensors record the pavement response while the HWD geophones record the defections on the pavement surface. These tests are conducted by placing the HWD load plate directly over the in situ deflection and strain sensors. One of the objectives of the HWD tests is to develop relationships between the applied load and measured deflections.The result of this research has shown that PCN value from analytical method is 9/F/A/X/T and theoritical method is 38/F/D/X/T. Code letter A or D on PCN value is describe about class of bearing capacity of subgrade. That difference of code letter bearing capacity due to HWD test directly collecting data of subgrade reaction under the pavement but the other method has taken data of subgrade from sample outside of runway . Increasing of bearing capacity of subgrade cause process of compaction on subgrade under the pavement has perfectly done
