Analisa Efisiensi Tebal Perkerasan Jalan Lingkar Kampus Itera Menggunakan Metode Perancangan Manual Disain Perkerasan (MDP) dan Metode Analisa Komponen
Full text linkRoad instalation is one of crucial sector which become connection zones of campus ITERA. Optimum
planning of design pavement is very necessery. Variable that affected the planning process of
pavement design on the road zone of ITERA is, CBR Subgrade value, Traffic loads factor, road
classification, and pavement types. Pavement design of ringroad inside campus ITERA planned
with 2 methods, the pavement thickness analysis method using Bina Marga 1987 and Pavement
Design Manual using Bina Marga 2013. Based of survey and analysis obtained CBR subgrade
with 6%-10%, traffic loads for 20Years reach 1.210.994, and region condition categorized as
tropical climate with rainfall around 1900-2500mm/year. Pavement design with the pavement
thickness analysis method using Bina Marga 1987 and Pavement Design Manual using Bina
Marga 2013 resulted variation thickness, MDP2013 with flexible pavemet HRS WC, HRS Base,
LPA class A and LPA class B resulted total thickness at 44cm while MAK1987 resulted at 35cm.
Significant differences is in LPA class A and LPA class B. By the studies, total thickness with the
pavement design manual 2013 is more thick than using the pavement thickness analysis using
Bina Marga 1987, this caused by some standard in the pavement design manual 2013

for clean water in the City of Bandar Lampung include: respondent characteristics, number of
family members, education status, type of work, number of vehicle ownership, and ease of obtaining
water. The cost of clean water needs issued by the people of Bandar Lampung City every
month ranges from Rp. 127,267.00 up to Rp. 187,449, 0. (4) The results that obtained in this study
are far different from the results of Kindler and Russel's (1984), which stated that the average water
use for households is 295 liters / person / day. But the results obtained in this study approached
the Planning Criteria Set by the Directorate General of Human Settlements, Public
Works Agency in 1996, which stated that the Big City, which is a city with a population of 500,000
- 1,000,000 people, has domestic water needs about 120 ltr/person/day until 150 ltr/person/day
Pengaruh Aksesibilitas dan Karakteristik Sosial Ekonomi Terhadap Mobilitas Masyarakat (Studi Kasus di Kecamatan Tanjung Karang Pusat Kota Bandar Lampung)
Full text linkThe purpose of this study is analyze the correlation of accessibility to the level of mobility and the
correlation of mobility to socio-economic in Tanjung Karang Pusat sub-district. The sample targets
are the people in Tanjung Karang Pusat sub-district as well as from the competent parties in
their field, using the random sampling technique. Data collection is done through questioner with
descriptive analysis method and PSPP analysis.
Based on the calculation of IRI (index of road infrastructure) value in Tanjung Karang Pusat sub
district, which is 5.74, the value almost meets the national minimum value requirement, which is
6. For accessibility index is 22,289 larger than MSS (>5,0) while for mobility index has a value of
1.355 smaller than MSS (minimum service standard) requirements that have been set which is >
2.0. The level of mobility is strongly influenced by the regional income itself. One way to increase
the IRI value is by adding a road network. The writer took Durian Payung urban village which
has a lot of vacant land area, which is increase 3.91 km and able to raise IRI to become 6,01 and
exceed national minimum value. In correlating the mobility with the socioeconomic obtained the
equation f(x) = 2,71+0,25X1+0,04X2+0,12X3+0,14X4 based on T-test the influential value is income.
Correlation of accesability with mobility obtained the equation f(x) =
1,64+0,004X1+0,37X2+0,0002X3 based on T-test the influential value is travel destination . Correlation
of accesability and socioeconomic with mobility obtained the equation f(x) =
2,12+0,11X1+0,03X2 based on T-test the influential value is accesability.
