Evaluasi Kinerja Angkutan Massal Bus Rapid Transit Pada Koridor Rajabasa - Sukaraja
Get PDFThe growing population and the increasing economic growth in the city of Bandar Lampung haveled to expanding geographic mobility within the city. The provision of a mass transit system,therefore, is vastly indispensable for anticipating high traffic densities. This study was trying toexamine whether the operational performance of trans-Bandar Lampung buses, or called “BusRapid Transit” (BRT), has conformed to the existing standards. The results are expected to betaken for consideration by the municipal government when adopting policies to improve BRT’soperational performance and to scale back traffic jams.The study focused only on one corridor, the Rajabasa-Sukaraja corridor, and used the World Bank(1986) standards as the reference. Observations were then made in three days: Monday andThursday to represent workdays, and Sunday to represent days off, with each observation dayspanning from 6.00 a.m. to 6.00 p.m.The results reveal that time headway, 6.29 minutes (on the Rajabasa-Sukaraja corridor), and tripspeed, 25.45 km/h, have met the World Bank’s standards. However, traveled distance, 112.36 kmper vehicle, and load factor, 20.53%, are below the given standards. This low load factor has led tosmall revenue per vehicle, i.e. only Rp346,503.56. Dividing the amount by the operating cost(operating ratio) per vehicle gives us a value of 0.7 (less than 1). In other words, the BRT systemhas been operating at a loss.In the final analysis, it is vital that the municipal government take strategic policies to reduce thenumber of minibuses, or angkot, that operates on the same corridor as the BRT buses’, so thatmore passengers will shift to these BRT buses. The government should also grant subsidiesimmediately to make up for the loss currently being suffered by this BRT.Keyword : BRT, trans-Bandar Lampung bus, Rajabasa, Sukaraja, time headway, load factor

Korelasi Kuat Tekan dengan Kuat Geser pada Tanah Lempung yang Didistribusi dengan Variasi Campuran Pasir
Get PDFThis research aims to determine the compressive strength and shear strength on clay which issubstituted with a mixture of sand variations. Soil tested in this study is derived from clay ofBelimbing Sari Village, Jabung District, East Lampung. This is done because if you set up astructure on top of the clay will cause some problems, among others, the small value ofcompressive strength and shear strength of the soil.To determine the effect of mixing clay with sand on the compressive strength and shear strength, itis done by varying the mixing of sand by 10%, 20%, 30%, 40%. From the test results it is obtainedthat the increase in shear strength to a maximum of 0.7534 kg / cm2 and a decrease in cohesionvalue of 0.10 kg / cm2 at mixing the sand as much as 40%. In the compressive strength reaches amaximum value at 30% of the mixing done 4 variation is equal to 0.4996 kg / cm3. The greater thelevel of sand were added then the lesser the value of the soil cohesion, friction angle and thecompressive strength will increase although the maximum compressive strength value in mixing30% sand.Keywords : Clay, Sand, Soil Compressive Strength, Soil Strength Pres
