Pengaruh Pintu Keluar Mall Bumi Kedaton dan U Turn Sebelum Lintas Jalan Rel di Jalan Sulta Agung (Studi Kasus Simpang Jl. Teuku Umar – Jl. ZA. Pagar Alam – Jl. Sultan Agung)

This research used primary data and secondary data. The primary data is obtained from the directsurvey result in the form of geometry data, environmental condition data, traffic flow, signaltiming, and long queues. Secondary data consists of the population in Bandar Lampungat 2012that is get from BPS Lampung Province. Data analysis is used the Indonesian Manual HighwayCapacity in 1997 for Signalized Intersections. Based on calculations, it can found that theintersection level of service at aftrenoon peak hour was F with a delay amount 61,50sec/pcu, levelof service at evening peak hour was F with a delay amount 88, 20sec/pcu, and level of service atnight peak hour was F with a delay amount 60, 29sec/pcu. Similarly, with the U Turn result canobtained the intersection level of service at afternoon peak hour was B, level of service at eveningpeak hour was B, and level of service at night peak hour was A.It indicates that the performance ofintersectionis not optimal. To increase the performance of the intersection, need make a changesin the pattern of setting time control become the pattern of not setting time control based on thepeak condition by changing the cycle time, green time, and inter green time. And therecommendation needed for the handling of openings U Turn on Jl. Sultan Agung.Keywords : signalized intersection, delay, performance, U Tur

Pengaruh Kuat Tekan dan Kuat Geser pada Sampel Dry Side of Optimum (Optimum Kering) dan Wet Side of Optimum (Optimum Basah) Tanah Organik

Organic soils causing many problems for the construction to be built on it, is generally caused bythe physical properties of organic soils that have a very high water content and low carryingcapacity, so that organic soils have less favorable properties for the construction of civil buildings.In this case, there should be a study of compressive strength and shear strength.This research wasconducted in the laboratory by making a sample of the results of a standard compaction, then thesample is done in Optimum condition Dry side of optimum and Wet side of optimum. On the DrySide Of Optimum process, sample was given a reduction of 10% of the optimum water content,while the Wet Side Of Optimum given the addition of 10% of the optimum water content, then thesample is done soaking for 4 days after compaction testing standards.The test results ofcompressive strength and shear strength shows a sample of soil behavior in an Optimumconditions better than the sample in Dry Side Of Optimum conditions and Wet Side Of Optimum.This is due to the pores of the soil Optimum conditions experienced stability and development ofthe soil is very minimum to occurs. Compressive strength and shear strength test is to measurehow strong soil receiving compressive strength and shear strength given to the soil separated fromthe grains.Keywords: Organic Soil, Dry Side Of Optimum, Wet Side Of Optimum, Optimum, CompressiveStrength and Shear Strengt

Studi Pemodelan Curah hujan sintetik dari beberapa stasiun di wilayah Pringsewu

This research conducted to study the characteristics of daily rainfall and model making ofsynthetic daily rainfall in Pringsewu regency using periodic model, stochastic model and periodicstochastic models. This research conducted using daily rainfall data with length of 1984-2013from three rainfall stations, Pringsewu, Wonokriyo and Banyuwangi rainfall stations.These models performed by using 512 days annual data. Using rainfall frequency obtained andapplying the spectral method and the least squares method, it can be generated the daily rainfallperiodic models. Rainfall stochastic model assumed as the difference between rainfall data withperiodic rainfall models. Based on data from the series of stochastic, the component wascalculated using the approach of autoregressive models. Stochastic model was presented by usingthe autoregressive model of order three. Periodic stochastic model obtained by merging periodicmodel and stochastic model. Model validation and data obtained by calculating the correlationcoefficient. Based on the results of this research, it can be concluded that daily rainfall time seriescan be very significantly approximately recorded rainfall data. With the the average value ofcoefficient correlation of periodic model is 0.98019, coefficient correlation of stochastic model is0.99808, and coefficient correlation stochastic of periodic model is 0.99993keywords: daily rainfall, autoregresif models, stochastic component

Studi Pemodelan Stokastik Curah Hujan Harian di Stasiun Kota Metro

The purpose of this research is to study the daily rainfall data series The data used daily rainfall data with data length in 1986-2013 at 3 stations namely Metro station R-206, R-107 Raman Dam, and Argoguruh R-106 are located in Metro City and the surrounding areas.The modeling is done using the data length of 512 days. By using the frequency of rainfall data obtained then apply the Fourier equation and the method of least squares is then generated model of periodic daily rainfall. Rainfall stochastic model of rainfall data is assumed as the difference between precipitation data with periodic rainfall models using the 253 components. Based on data from a series of stochastic, stochastic component is computed using autoregressive models approach. Stochastic model presented by using the autoregressive model of order three. Validation stochastic series, between the data and the model is done by calculating the correlation coefficient.Based on these results we can conclude synthetic daily rainfall data time series obtained very significant approach measurable rainfall. With the value of the average correlation coefficient stochastic model is 0.9981.keywords: daily rainfall, autoregresif models, stochastic component

Model Emisi Gas Buangan Kendaraan Bermotor Akibat Aktivitas Transportasi (Studi Kasus: Terminal Pasar Bawah Ramayana Koita Bandar

Ramayana Underground Terminal of Bandar Lampung City is one of the largest contributorsexhaust emission levels, where the freight car transport activity is very high. Transportation is oneof the activities that contribute as a producer of motor vehicle exhaust emissions both gasolineand diesel.The aim of this study is to make model the relationship between vehicle exhaust emissions withtransport activity, to determine the factors that affect emissions, calculate emissions, and calculatethe emission losses in rupiah per year in Ramayana Underground Terminal of Bandar LampungCity.Relationship models obtained from the linear regression equation using SPSS 16 for dieselpassenger cars is Y = -19,401 + 0,684 X1 + 11,497 X2 +0,031 X3 and for gasoline passengercars is Y = 20,060 + 0,143 X1 + 0,421 X2 + 0,028 X3 and for motorcycles is Y = 9,049 + 0,082X1 + 0,921 X2 + 0,051 X3.

Perilaku Penurunan Tanah Terhadap Dry Side of Optimum dan Wet Side of Optimum pada Kepadatan Tanah Organik

The decline in soil organic matter due to the burden of its own soil and building construction thereon are not able to with stand the load that lasts. Of these conditions need to know the factors thataffect soil instability, through soil behavior can be observed with the organic content of the soilwater content. The compaction is the beginning of the formation process for testing the strength ofthe soil, so that the pattern of behavior can be identified by soil Dry and Wet Side of Optimum Sideof Optimum.Soil test results Decrease Behavior Against Dry and Wet Side of Optimum Optimum At the Side ofOrganic Soil density, Dry Side of Optimum sample / sample with 5% dry compaction over the bestsample for the fastest processing speed and magnitude of soil degradation as well as the smallestdecrease in the reduction process quickly said to be good for the soil more quickly reach the soillayer in a stable condition and the magnitude of the smallest drop is quite good because thecompression process a smaller type of soil, thereby reducing the risk of damage to the constructionthereon that the Cv value obtained by 0,168cm 2 / sec, Cc for 2.33, and AV 0.28 cm 2 / sec.Keywords: Organic Soil, Compaction, Dry Side of Optimum, Wet Side of Optimum, and SoilDeclinel
