Abstract

Gasoline is an important item and becomes a basic need for the community. Subsidized gasoline in Bandar Lampung experienced sales restrictions according to the specified quota. The price of subsidized gasoline which is cheaper than non-subsidized gasoline makes people willing to wait to get subsidized gasoline. This study aims to determine the factors that influence the selection of gasoline types and determine the preferences of each private vehicle user in choosing gasoline, both subsidized gasoline and non-subsidized types. This research uses AHP (Analytical Hierarchy Process) methodBased on the results of the analysis conducted on the group of civil servants, non-civil servants and students, it was found that the group of non-civil servants chose Premium which was the most priority with a weighting value of 0.3745, then for Pertalite of 0.3156 and Pertamax 0.3108. Then for the group of civil servants, the greatest or priority results were Premium with a value of 0.3457, then Pertamax with a value of 0.3350 and Pertalite with a value of 0.3205. Then, for the Student group the most priority results are Premium of 0.3479, then Pertalite of 0.3288 and Pertamax with a difference not too far at 0.3263.

Abstract

One of the causes of construction failure on asphalt pavement is segregation. Which  is the separation of small and large aggregate grains within a mixture, so that in a part of the coating of the pavement will be concentrated aggregate coarse and in other part will be concentrated fine aggregate. One of the factors causing segregation is the hauling distance from Asphalt Mixing Plant to the slap location. To understand this, task a study on the impact of the transport process on segregation on hot asphalt mixture from Asphalt Mixing Plant to the location of the spread. The mixture used is the Asphalt Concrete-Wearing Course type or the laston coated wear of Asphalt Mixing Plant PT. Gigging Polah Raya for work location which is 28.9 km on Jalan Sultan Agung, Bandar Lampung, Lampung and PT. Rindang Tigasatu Pratama for work location located 53.3 km on Jalan Teuku Cik Ditiro, Bandar Lampung, Lampung. Examination of sample is done trough extraction test and sieve analysis test. From the result of the research, it’s found that there is being segregation during the transport of asphalt mix mixture from Asphalt Mixing Plant to the slap location. For sample PT. Manggung Polah Raya, gradation aggregate is still within the upper and lower limits of the general specification Bina Marga 2010. As for the sample of PT. Rindang Tigasatu Pratama, the aggregate gradation is out of the upper and lower limits of the general specification of Bina Marga 2010. Factors affecting segregation are haulage distances and aggregate density. Keywords: Road Pavement, Asphalt Concrete, Segregation.

Abstract

The increasing number of motorcycle vehicles, causing traffic congestion at the signal intersection in Bandar Lampung City. As an effort in reducing congestion, the government of Bandar Lampung city made Special Stopping Space (RHK) for motorcycles. The RHK is a space dedicated to arrange motorcycle queue place when stop at the signalized intersection during traffic light period. This study aims to examine the effectiveness of RHK at the signalized intersection, and it’s impact on saturation current increase and approach capacity compared to approach without RHK. The effectiveness and impact of RHK, was conducted by surveying traffic flow in the morning during peak hours using camera video in each selected approaches. The survey data obtained were analyzed using MKJI and compared with previous research. RHK increases saturation flow 7,3% - 17,5% and approach capacity 37,67% - 52,09%. In conclusion RHK is effective to be provided in signal intersection. Value of RHK filling level at Jl. P. Diponegoro - Jl. P. Diponegoro and Jl. Jend. Sudirman - Jl. Gajah Mada - Jl. Jend. Sudirman is less than 50% that indicates bad while at Jl. Jend. Sudirman - Jl. Jend. Sudirman and Jl. Dr. Susilo - Jl. P. Diponegoro is 50% - 80% that indicates moderate.  Keyword : RHK (SSSM : Special Stopping Space for Motorcycle), signal intersection, effectiveness of RHK, saturation current, capacity of the approach

Abstract

Produk beton tiang pancang (TP) memiliki variasi ukuran dan panjang yang berbeda yaitu 6 sampai 20 meter, pada setiap panjang yang berbeda mesin pemotong precast concrete (PC) bar yang berfungsi untuk memotong tulangan TP dilengkapi dengan stopper berupa besi pelat di ujung pelurus dan sensor magnetik. pneumatik sebagai alat yang mendeteksi panjang PC Bar dan memberikan perintah Programmable Logic Control (PLC) untuk memulai pemotongan PC Bar, kelemahan dari sistem ini adalah anda harus memindahkan letak plat stoper secara manual untuk setiap panjang yang berbeda. Pemotongan PC Bar akan memakan waktu yang cukup lama, jika tipe panjang potong berbeda beda. Untuk meningkatkan otomatisasi dan efisiensi waktu setting perubahan panjang potong dan efisiensi waktu pemotongan PC Bar, sistem stoper berupa plat dan sensor magnet pneumatik dapat diubah dengan menggunakan rem kopling sebagai sistem pengereman untuk putaran roda rol feeder yang digunakan saat menarik dan mengukur panjang PC. Sensor bar dan enkoder untuk mendeteksi jumlah putaran enkoder roller yang diubah menjadi panjang PC Bar yang akan dipotong, kemudian keluaran dari sensor enkoder dihubungkan ke counter meter sebagai tampilan jumlah putaran dan menjadi masukan PLC untuk mulai memotong PC Bar.

Abstract

As the capital city of Lampung Province, traffic density in Bandar Lampung City cannot be avoided. Due to the density of existing traffic flow, transportation facilities need to be improved. Transportation facilities improve can be done with many examples of traffic engineering, like make an intersections, roundabout, underpasses, flyovers, etc.  In the Pramuka traffic area, the government took the decision to make a fly over. The construction of fly over Pramuka – Indra Bangsawan impressed not pay attention to the applicable geometric standard of urban roads, so it needs to be evaluated to find out the safe speed to cross on it. The research method is by first searching for the ideal radius length after that searching for the ideal arch length which will be compared with the existing arch length.  The result, a safe passing speed when crossing the fly over is 18 km / h (full circle) and 16 km / h (spiral-spiral), and at the cross over fly over is 12 km / h (full circle) and 8 km / h (spiral-spiral). Speed requirements for urban road plans are 30 - 50 km / h, so it can be concluded that the construction of fly-over pramuka - indra bangsawan has not met the applicable urban road planning standards.

Abstract

Choosing the right mode of transportation is something that passengers want, but with the advantages and disadvantages of existing transportation modes can affect the number of users of these modes of transportation. The purpose of this study was to determine the factors and probability of choosing the mode of passenger transportation between trains and buses with the Bandar Lampung - Palembang route. The method used in this research is the Discrete Choice Model method, with the analysis used is linear regression analysis of the two models used, namely the difference binary logit model and the binary logit ratio. Based on the research results, the probability value from the bus mode selection analysis is known if the value (∆C) = 0, the probability value with the binary logit model is the difference = 35%, and if the value (∆C) = 100000 then the probability value increases to 41%. Meanwhile, if (C1 / C2) = 0.1, then the probability value with the binary logit model ratio = 58%, and if the value (C1 / C2) = 1 then the probability value increases to 35%. From the results of the analysis carried out, the dominant factors influence the choice of mode of transportation by route Bandar Lampung - Palembang is the cost of transportation cheap, and comfort level of service.Keywords : modal choice, binary logit, discrete choice model, probability
