Abstract

The degression of road performance was caused by several factors, particularly by road side activities. Tuanku Tambusai Road, the front side of Mall SKA is an economic region with large volume of traffic. This condition could be assumed in case the traffic volume gets higher, it will decrease the performance of road side, especially on busy hours due to the movement of vehicles to SKA Mall, the stopping public transportations, street vendors, and the parking motorcycles at road side. This research aims to evaluate the performance of Tuanku Tambusai Road, at the front of SKA Mall and find some solutions to overcome theproblems. The road performance analysis was based on Manual Kapasitas Jalan Indonesia (MKJI) 1997. The traffic data was collected from 3 days long, i.e. Saturday (3/2/2018), Sunday (4/2/2018) and Monday (5/2/2018). The results showed that busy hour was happened on Sunday at 12.45-13.45 WIB with Q = 2579,6 smp/hour, C = 3234 smp/hour dan DS = 0,80. Due to DS was higher than MKJI standard, which is DS < 0,75 some planning needs to be done in order to increase the performance of road. In order to reach the maximum standard, a specific lane was planned for vehicles which made their way into SKA Mall. The results showed that DS was able to meet MKJI standard, i.e. DS = 0,59.Keywords : Road Performance, MKJI 1997, Side Activities.

Abstract

This paper investigated how much the public's willingness to pay (WTP) for the cost of public water supply services (PDAM) in Pekanbaru City. This research also projected how much urban water demand of this city for period of 2014-2032. This study divided samples into two categories, namely (i) middle and high income society, and (ii) low income one. These categories were based on the type of house ownership, and the percentage of low income family in this city This research obtained two main factors affected to the WTP for public water services (Y), such as; (i) the number of family members (X1), and (ii) the amount of family income (X2). The equation formula of Y = -677.816 + 12934.502 X1 + 0.012 X2. The average public’s willingness to connect to PDAM for the middle and high income society was 62.13% and for the lower class was 44.44%.There was a trend that the middle and high incomes society’s water demand was relatively higher than that the lower one.  The amount of water tariffs for middle and high income class society was at the average of Rp.6.615 / m3, and Rp.4.971/m3 for the lower income one. This tariff was higher than the average tariff in 2014 (Rp. 3,300 / m3). The water supply capacity in 2014 was estimated to 620 l/sec, and it was projected that water demand in 2032 will increase to 3,946 l/sec (three folds). Tulisan ini meneliti berapa besar keinginan masyarakat untuk membayar biaya pelayanan pengadaan air bersih (PDAM) di Kota Pekanbaru dan membuat proyeksi kebutuhan air bersih Kota Pekanbaru 2014-2032. Sampel calon pelanggan air bersih dalam penelitian ini dibagi atas dua kategori, yaitu (i) masyarakat kelas menengah keatas, dan (ii) kelas menengah kebawah. Penelitian ini mengidentifikasi dua faktor utama yang mepengaruhi keinginan masyarakat menengah ke atas membayar pelayanan air bersih PDAM (Y), yaitu; (i) jumlah anggota keluarga (X1), dan (ii) besarnya pendapatan keluarga (X2), dengan formula Y= -677,816 + 12934,502 X1 + 0,012 X2. Keinginan untuk menyambung pada masyarakat menengah keatas sebesar 62,13% dan di kelas menengah kebawah adalah 44,44%. Besarnya tarif air bersih yang diinginkan masyarakat menengah keatas Rp.6.615/m3 dan Rp.4.971/m3 untuk kelas menengah kebawah.Tarif ini lebih tinggi dari rata-rata tarif PDAM pada tahun 2014 yaitu Rp. 3.300/m3.Kapasitas pasokan PDAM air pada tahun 2014 adalah 620 l/detik, namun diproyeksikan kebutuhan air bersih meningkat menjadi 3.946 ll / detik untuk tahun 2032.

Abstract

There are methods that can be used to evaluate pavement conditions, such as Bina Marga and PCI (Pavement Condition Index) methods. In the Bina Marga method, the determination of road condition values are done by summing numbers and values of damage conditions, while PCI method is based on type, rate and area of distresses. This study attempts to compare the two methods in determining a road segment pavement condition (i.e. segment of Simpang Lago to Simpang Buatan, Riau). The road segment was divided into 6 sub segments. Primary data obtained from field surveys and secondary data were used. The priority of pavement maintenance actions was ranked from 0 to 7 for Bina Marga method, and from 0 to 100 for PCI method. The comparative analysis showed different results between the two methods in terms of pavement condition values and maintenance actions. Based on each method’s pavement condition rank, the condition values of the sub segments were 9, 10, 10, 10, 9, 10 for Bina Marga method which all needed for routine maintenance. The PCI method gave larger range of condition values, i.e. 82, 79, 57, 28, 28,and 27.keywords :pavement condition,bina marga, PCI

Abstract

Soil stabilization for the runway sub-grade in Tampuling Airport, Tembilahan, Riau province is required as the existing soil is in the grouped of peat or soft soil. The compressibility rate of this soil is very height, with the depth of the soft soil of more than 30 meters from its surface. Based on “the worst case scenario” without any soil stabilization treatment, it was estimated that the soil consolidation rate would be 1.7 metre within 20 years period of settlement. In order to speed up consolidation process, the vertical drain method was applied. Design of pre loading technique as well as the calculation of distance between vertical drains is then demonstrated in this paper. It was estimated that the depth of vertical drain would be 18 metres, with the distance between vertical drains is 1.2 metres each; height of pre loading is 4.5 metres. With these design parameters, it was expected that the settlement process would be accelerated by 40 folds (235 months to become 6 months period). Keywords: Vertical Drain, Pre-Loading, Settlement, Consolidation, Sub-Grade. ABSTRAK Perbaikan sub-grade untuk menopang perkerasan lentur runway bandara Tampuling di Tembilahan, Propinsi Riau perlu dilakukan karena sub-grade nya terdiri atas lapisan tanah gambut dan tanah lunak. Tanah ini mempunyai kriteria sebagai tanah dengan tingkat kompresibilitas tinggi mencapai kedalaman 30 m. Berdasarkan skenario terburuk, setelmen konsolidasi tanpa ada perbaikan tanah (sub-grade) akan terjadi sebesar 1,7 meter dalam 20 tahun (235 bulan). Upaya untuk mempercepat konsolidasi dilakukan dengan memasang drainase vertikal (vertical drain). Perencanaan tinggi pre-loading, dan spasi drainase vertikal berikut kedalamannya mempengaruhi proses kecepatan konsolidasi dianalisa. Hasil perencanaan yang diusulkan adalah sebagai berikut; (i) kedalaman drainase vertikal = 18 m;(ii) spasi antar drainase = 1,2 m; dan (iii) tinggi preloading = 4,5 m. Setelmen yang direncanakan dapat dipercepat sebesar 40 kali dari semula 235 bulan menjadi sekitar 6 bulan.Kata Kunci : Drainase Vertikal, Preloading,  Setelmen, Konsolidasi, Tanah Dasar/Sub-gradePermalink: http://ejournal.undip.ac.id/index.php/mkts/article/view/3697[How to cite: Sandhyavitri, A., Wibisono, G., Juniati, S. dan Rioputra, M.D. (2008), Analisa Perbaikan Sub-Grade Runway Lapangan Terbang dengan Metode Vertical Drain (Studi Kasus Bandara Tempuling  di Tembilahan, Propinsi Riau), Jurnal Media Komunikasi Teknik Sipil, Tahun 16, Nomor 3, pp. 231-242]

Abstract

Time delay in the project execution phase causes cost escalation. This paper demonstrated the magnitude of severness of time delay affected to an increase of the project cost during the construction of bridge in Indragiri Hulu District. It wa evaluated that the project construction program was planned for 120 days but it was delayed up to 255 days. The time delay of 135 days within the project affected an increase of the constractor’s additional expenses about Rp. 703 million. By simulating various parameters of risks, it was found that; (i) based on the “what it is” scenario, 80 % probability the project was predicted to delay up to 118 days (cost of Rp 686 million); and (ii) by the implementation of risk management procedure encompassing 6 (six) risk mitigation elements it was estimated that 80% probablility of project delay may reach 46 days (cost Rp 361 million). The reduction of time delay and cost overruns may reach 50%.  Hence, it demonstrates that the implementation of risk management procedure may control project risks systematically.

Abstract

The development of air transportation in Minangkabau International Airport-Padang Pariaman had indicated that the existing capacity of terminal building was overcapacity with average 2,9 million number of passengers per year was no longer able to accommodate the volume of passengers. It also can be identified through the escalation amount of passenger that reach 3,1 million passengers in 2015. The expansion plan was done by forming equation of multiple linier regression between the volume of passenger as dependent variable with total population, PDRB (Product Domestic Regional Bruto), income per capita and tourist as independent variable. The prediction number in certain year was generated with 328377+0.062Pkt equation and tourist variable with -36623+0,097Wtb equation. The result of terminal building expansion plan area in 2035 should not be less than 65.233m2 with 7.402.896 number of passengers capacity and also able to accommodate 3782 passengers during a peak hour.Keywords : Terminal Building, Forecast
