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 â€œthe worst case scenarioâ€ 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,Â 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 TempulingÂ di Tembilahan, Propinsi Riau), Jurnal Media Komunikasi Teknik Sipil, Tahun 16, Nomor 3, pp. 231-242]

A peatland is an area with naturally accumulated decayed organic materials (peat) at the surface. Riau Province has the largest peatlands in Sumatra i.e. 56.1% from the total peatlands in Sumatra. Peat fires have been many times occurred in Indonesia. Stabilization proven to preverent peat fire in Malaysia. Most common available stabilization materials are cement and lime. Research conducted by Zamzam (2017) showed that peat mixed with 5% lime and 15% cement at 100% moisture content, could increase its strength and became less combustible. This research attempts to correlate the mechanical properties of peat that stabilized with cement and lime at various water contents, and its burning resistance. Several water contents applied were 51.52%, 76.77%, 81.82%, 102.02%, 107.07%, and 112.12%. The burning tests were not conducted on sample of 51,52 % water content. The result showed that the optimum strength of stabilized peat mixtures achieved at water content of 76,77%, which had UCS and soaked CBR value of 97.35 kPa and 16,23%, respectively. The burning test showed that the higher the water content, the delay combustible the peat sample,however the mechanical test and burning tests showed the opposite results.Keywords: peat fire, cement, lime, CBR, and UCS.

Plastics have been used for many consumer goods. Polyethylene Terephthalate (PET) is commonly used as non-reusable water bottles. Although the plastic can be recycled and has economic values, the unhandled waste still threatens the environment. PET based waste products have been used as pavement materials in limited applications. This research attempts to investigate the effect of PET waste addition on binder course asphalt concrete (AC-BC) mixtures. The proportion of PET waste added into bitumen was 0, 2, 4, and 6% of bitumen content. Bina Marga 2010 Specification was used to obtain optimum asphalt content and to measure all Marshall characteristic of all samples tested. The results show that the addition of PET waste increased the stability and flow values of mixtures. The optimum PET waste content that still meets the specification was 4% of bitumen content.Keywords : plastic waste, marshall characteristic, AC-BC.

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

Fires in peat land in Riau Province commonly happened in the dry season and the water level of peat land was low. To reduce the risk of fires in peat soil can be implemented with the solidification and stabilization. Stabilization of peat soil by used additive ingredients such as chalk (CaCo3) and fly ash was one method of soil stabilization. The Additive ingridients could improve the technical properties and filled the voids in the peat soil was reduced. This research was aimed to determine the optimal composition content of chalk and fly ash to the stabilization of burning peat soil. The optimum water content for compaction was range between 100% and 160%, Hadijah (2006) in Ilyas (2008). Based on literature, this research using 100% water content for compaction. The pure peat soil was burned at the optimum water content and temperature obtained burning point at 72 °C within 4 minutes. After peat stabilization with fly ash 15% and 5% CaCO3, burning point was much longer to 94 °C within 34 minutes. Higest point of ash happened on peat soil with fly ash 15% and CaCo3 5% with a temperature of 206 °C and within 59 minutes. Meanwhile, ingredient content such as peat soil+ 5% CaCo3 + 10% fly ash, peat soil + 5% caco3 + 5% fly ash, and on pure peat soil has a short time. It was because the fly ash and chalk can be reduced the burning process time.Keywords: Peat Soils, Fly Ash, Chalk, Burning Point, Ash Point
