SNI 1726:2012 states that surface spectral accelerations SMS (0.2 second) and SM1 (1 second) can be calculated by multiplying site factors Fa (0.2 second) and Fv (1 second) with spectral accelerations SS (0.2 second) dan S1 (1 second). All site factors used by SNI 1726:2012 are adopted from ASCE/SEI 7-10.Â In 2013 Stewart and Seyhan proposed new and different site factors compared to ASCE/SEI 7-10. These site factors are then used for developing ASCE/SEI 7-16 with minor improvement for site class SE (soft soil). ASCE/SEI 7-16 states that the site factors for site class SE with SS greater than 1g or S1 greater than 0.2g, shall be calculated using Site Specific Analysis (SSA). The SSA method used for calculating site factor is difficult for ASCE/SEI 7-16 to be implemented in Indonesia. This paper describes the result of SMS and SM1 study at five cities (Jakarta, Bandung, Semarang, Yogyakarta and Surabaya) for site class SC, SD and SE using site factors proposed by Stewart and Seyhan and site factor SNI 1726:2012. The SMS and SM1 at five cities calculated using site factors proposed by Stewart and Seyhan are Â±15% differences compared to SMS and SM1 calculated usingSNI 1726:2012 site factors.

Beberapa tipe dinding penahan tanah seperti tipe kantilever, leaning, gravity ataupun dinding tanah perkuatan telah banyak dibuat orang, khususnya untuk menstabilkan suatu tanah pada badan-badan jalan baru. Pemilihan tipe dinding penahan tanah yang cocok untuk suatu daerah bukanlah suatu hal yang mudah, karena banyak faktor yang harus dipertimbangkan misalnya beban gempa.Â Keruntuhan yang dramatis dari dinding-dinding penahan akibat gempa Kobe 1995 di Jepang telah disampaikan oleh para ahli. Pengalaman ini menunjukan bahwa dinding tipe tanah perkuatan memperlihatkan prilaku lebih baik dibandingkan dengan dinding tipe lainnya. Padahal kesemua dinding telah direncanakan atau didisain dengan peraturan yang sama. Pengujian di laboratorium maupun di lapangan memperlihatkan tendensi hasil serupa.Kata kunci : Dinding penahan tanah, stabilitas, beban gempaPermalink: http://www.ejournal.undip.ac.id/index.php/mkts/article/view/3887[How to cite: Munaf, Y., 2004, Pengujian Tilting dan Shaking Table untuk MengkajiÂ Stabilitas Dinding Penahan Tanah Akibat Beban Gempa, Jurnal Media Komunikasi Teknik Sipil, Volume 12, Nomor 3, pp. 38-48]

Studi ini menyajikan karakteristik dasar tanah lunak kohesif yang terdepositkan pada jalan akses ke Bandar Udara Saga, Jepang. Serangkaian seri pengujian telah dilakukan guna mengakses parameter dasar deposit dalam kaitan tipikal perilaku tanah tersebut; sensitivitas tinggi, kompressibilitas tinggi, dan daya dukung tanah rendah. Perilaku dasar deposit memiliki karakteristik menyerupai profil geologisnya yaitu deposisi endapan lunak dengan variasi ketebalan 20-25 m. Beberapa lapisan pasir tipis secara random terdepositkan dengan fungsional sebagai lapisan drainase. Lapisan atas pada kisaran tebal 6 m merupakan tanah lanau, dibawah lapisan tersebut adalah deposisi lanau - lempung lunak. Kadar air natural deposit lebih tinggi dibandingkan nilai batas cairnya, permeabilitas lapisan lanau kelempungan diaproksimasikan 3 â€“ 5 kali nilai permeabilitas lempung Ariake pada umumnya. Struktur geoteknis yang dibangun diatas deposisi tersebut dilaporkan sarat dengan permasalahan penurunan dan keruntuhan pondasi akibat rumitnya perilaku deposisi tanah lunak tersebut. Tipikal kecendrungan kegiatan reklamasi dikawasan pantai telah meningkat secara signifikasi akibat keterbatasan lahan pengembangan infrastruktur, permintaan lahan rekrutan dilaut dangkal, dan lahan buatan tepi pantai. Besarnya penurunan pada badan jalan raya dan kerusakan berat bangunan lepas atau dekat pantai akibat aksi gempa, beban lalu lintas, dan gelombang badai adalah merupakan tipikal permasalahan geoteknis yang menjadi perhatian serius bagi birokrat, peneliti, dan praktisi di kawasan tersebut.

Labor wages have a large portion (approximately 30%) of construction contract value. Therefore, company should pay attention to labor wages. Unfortunately, existing data about construction labor wages in Indonesian are only showed as daily wages (for labor) and monthly wages (for employee/permanent staff), while thereâ€™s no information about their labor burden. Therefore, objectives of this study are to identify the component and structure of construction labor burden and wages in Indonesia and also to identify all factors related. Research method used int this study are empirical and inductive methods. After all data has been collected from field survey, description of the construction labor burden and wages model was compiled into its components. Moreover, comparison analysis used to identify factors related to construction labor burden and wages. Results of data processing and analysis shows that: 1) Construction labor burden in Indonesia for both employee/permanent staff and labor commonly consist of direct and indirect payment, and conditional and lumpsum payment, but there are different distributions between each kind of labor. 2) Construction labor burden and wages in Indonesia commonly depend on company profile, project profile, and labor profile.

The construction industry has a significant role to the contribution of the development both in developed and developing countries.Â The importance of the industry is not only in its product but also in the scale of the industry, its share in the national economy and how it affects society. Moreover, construction products, such as roads, bridges, railways, irrigation, schools, hospitals, dwellings, offices and factories are an important element in the economy and in improving living standards. An important issu of the construction industri in developing countries is to improve the quality of the industry due regard to social, envronment and sustainability aspect.Â One of the alternative solution is to develop a Construction Industry Development Board (CIDB).Â However, the detailed way in which all of aspects in the CIDB interact is not well understood.Â This paper presents a possible system of CIDB model by using a prototype model from National Accreditation Body of Higher Education System.Keywords: construction industry development, government, CIDBPermalink: http://www.ejournal.undip.ac.id/index.php/mkts/article/view/3953[How to cite: Wibowo, M.A. dan Hadihardaja, J., 2006, Badan Akreditasi Nasional Industri Konstruksi Suatu Kebutuhan, Jurnal Media Komunikasi Teknik Sipil, Volume 14, Nomor 3, pp. 277-286]

The concept of earthquake resistant houses is basically that all building components must be well tied each other. In addition, quality of materials and workmanship must also be good so as to produce a strong building when receiving shocks. This study aims to determine whether houses in Perumahan Graha Arradea (Tahap 3 in Ciherang Village, Dramaga Subdistrict, Bogor District - West Java are built following the design principles of earthquakeÂ resistant houses. The research is conducted by observing the construction process at the location. Every stage of the construction process is recorded using a digital camera (Sony Cyber-shot DSC-W730). Interviews are also conducted on related parties to obtain accurate informations. The results conclude that the houses that are built have not met minimum requirements for design of earthquake resistant masonry houses with reinforced concrete frame. In addition to quality of some materials that have not met minimum requirements, the quality of workmanship of building component is also still low. The ties of all building components have not been properly connected.

Seismic performance of reinforced concrete frame Buildings which have been designed as Special Moment Resisting Frames in accordance to three Indonesian codes (SNI 1727-2013, SNI 1726-2012 and SNI 2847-2013) can be evaluated using nonlinear dynamic analysis. Criteria related to strength such as component plastic rotation capacity, lateral displacement as well as criteria related to damage of elements in the structures were used to evaluate the seismic performance of the buildings. Assessment to the moment and curvature capacities of the cross sections of beams and columns were done using XTRACT. The global seismic performance of the structures depends on the seismic performance of components in the structures. In nonlinear model of the structures, the degrading strength of the components were modeled to take into account the gradual reduction of the contributed components to the resistance of the structures. PERFORM-3D is one of the software that can be used to generate nonlinear model of structures. Seismic performance level of structures can be obtained from the results of the nonlinear dynamic analysis using PERFORM-3D. The Seismic performance level can be utilized for: (1) detecting any weaker part in the structures, and (2) evaluating the improved design of the structures for enhancing the seismic performance of structures.

Analisa Perbaikan Sub-Grade Runway Lapangan Terbang dengan Metode Vertical Drain (Studi Kasus Bandara Tempuling di Tembilahan, Propinsi Riau) Sandhyavitri, Ari; Wibisono, Gunawan; Juniati, Sri; Rioputra, M. Dian

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]
