Several methods for evaluating the effect of site specific condition of soil layers against earthquakes are presently available. Site Specific Analysis (SSA) and Horizontal-to-Vertical Spectral Ratio (HVSR) are two methods commonly used for estimating the amplification factor of soil layers above bedrock. SSA can be performed using subsurface shear wave velocities and dynamic soil properties (density, shear modulus and damping). The HVSR is a simple method for estimating the site amplification factor. Based on the time and budget requirement HVSR is more efficient and effective compare to SSA method.This paper presents result of SSA and HVSR methodscomparison for estimating the amplification factor of soil layers. Two boring locations and six single station seismometer tests were perform within Tembalang District Area.

One main problem characterizes linear programming is to seek the maximum or minimum of a linearexpression when the variables of the problem are subject to restrictions in the form of certain linearequalities or inequalities. Problems of this kind are encountered when we have to exploit limitedresources in an optimal way. Project Cost Evaluation which play an important role in project are ofspecial significance in this respect. The real problem of Project Cost Evaluation analysis are tomanipulate cash flow problems of project into linear programming model or mathematical model.This method should be selected technically according the actual condition of the project. In designingand selecting the mathematical models, it is necessary to take into consideration the relationshipbetween the limited resources (money) and the optimal solution.

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. 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 ±15% differences compared to SMS and SM1 calculated usingSNI 1726:2012 site factors.

The Horizontal-to-Vertical Spectral Ratio (HVSR) is a simple method for estimating the resonance frequency of sedimentary layers. This method can also be used for estimating the site amplification factor. By using the resonance frequency and the amplification factor HVSR method can also be used for predicting the depth of the bed rock or the thickness of sediment layer (Nakamura, 1989). This paper presents results of HVSR method applied to ambient vibrations for estimating the amplification factor of sedimentary layer. A total of 16 ambient vibration measurements were performed in the City of Semarang to predict the amplification factor for the shallow sedimentary layers.

SNI 1726- 2012 has been implemented and used as basic guidance for earthquake-resistant building design. This regulation replaced RSNI 1726- 2002 which is not suitable for Indonesia’s area that always undergoes earthquake. Siloam Hospitals Medan Building was designed by RSNI 1726- 2002. This journal describes the result of Siloam Hospitals Medan Building’s calculation by SNI 1726- 2012. Structural analysis of Siloam Hospitals Medan Building is calculated by SAP2000 software. The outputs are internal forces which are used to calculate the dimension of structure and bar which is needed. This structure uses the method of Special Moment Resisting Frame which is expected that it has a high ductility due to its location where is in soft soil earthquake risk area.

Tanah merupakan dasar dari suatu struktur atau konstruksi, baik itu konstruksi bangunan maupun konstruksi jalan, yang sering menimbulkan masalah bila memiliki sifat-sifat yang buruk. Sifat-sifat tanah yang buruk dan kurang menguntungkan bila digunakan sebagai dasar suatu bangunan atau kontruksi, antara lain plastisitas yang tinggi, kekuatan geser yang rendah, kemampatan atau perubahan volume yang besar dan potensi kembang susut yang besar. Berbagai cara digunakan untuk memperbaiki kekuatan dari tanah lempung ekspansif, diantaranya dengan penambahan bahan kimia (stabilisasi secara kimiawi). Untuk mengatasi permasalahan yang ada pada tanah lempung eksapnsif maka diadakan penelitian dengan menggunakan soda api (NaOH) sebagai bahan stabilisasinya. Sampel tanah lempung ekspnasif diambil dari daerah Godong – Purwodadi Km ± 49,Jawa Tengah. Komposisi campuran soda api (NaOH) sebesar 7,5 %.Hasil penelitian menunjukkan bahan stabilisasi soda api (NaOH) belum dapat memperbaiki sifat fisik dan mekanik tanah lempung ekspansif. Pada sifat fisik : berat volume, kadar air, berat jenis, dan batas-batas Atterberg mengalami kenaikan setelah distabilisasi.

Site soil classification provides vital information for predicting the soil amplification or the site factor. The site factor is important for calculating the surface spectral acceleration in the seismic design of buildings. Based on the Indonesian seismic code, site soil classification can be conducted by calculating the average standard penetration (N-SPT) resistance, the average shear wave velocity (VS) and the average undrained soil strength (Su) of the upper 30 m of a subsoil layer. Different results may be obtained at the same location when the site soil classification is predicted using N-SPT than when using VS data. The restriction of N-SPT values until a maximum of 60 compared to a VS maximum of 750 m/sec can produce different soil classes and will directly impact the calculation of the surface spectral acceleration. This paper describes the different results of site soil classification prediction calculated using the average N-SPT and the average VS, conducted at Semarang City, Indonesia. Site soil classification maps developed based on both datasets are also presented, to evaluate the different site soil classification distributions. Only soil classes SD and SE were observed using N-SPT maximum 60, whereas soil classes SC, SD and SE were observed using N-SPT maximum 120.

Disaster mitigation due to seismic load (earthquake) needs to be considered. This is especially for dam structure used as a reservoir and water resource. Because of the main function, and building dimension is too large, thus if the dam collapse it will cause a significant catastrophe for the surrounding community and environment. One of the seismic damages to the dam is deformation. This paper presents the effect of seismic load on deformation of dam model simulation. This study took place on the Sermo Dam, Yogyakarta which is located close to Opak Fault –as the suspicious cause of the earthquake in Yogyakarta. Seismic loads used in this study in terms of acceleration time histories. Therefore model can be carried out using PLAXIS simulation. This selected seismic load variations are on the range 5.0-7.0 Mw and epicentrum distance is also restricted in 15-31 Km based on the nearest epicentrum distance between Sermo Dam and Opak Fault. Keywords: seismic load, deformation, dam, modeling

ABSTRAKIndonesia merupakan salah satu negara yang dilalui oleh cincin api sehingga negara ini sering dilanda gempa. Indonesia juga diapit oleh 3 lempeng yaitu lempeng benua Eurasia, Indo-Australia dan lempeng Pasifik. Gempa yang terjadi dapat berupa gempa tektonik maupun gempa vulkanik. Guncangan dari gempa tersebut dapat merusak struktur bangunan. Maka, perlu diadakan penyelidikan mengenai ketahanan suatu bangunan dalam menerima guncangan gempa. Ketahanan suatu bangunan dapat dilihat dari struktur kolom dan pondasi karena jika struktur tersebut hancur maka struktur bangunan akan roboh. Ketahanan struktur bangunan terhadap gempa bumi disebut uji sensitifitas bangunan. Studi ini dilakukan untuk mengukur ketahanan bangunan terhadap gempa dengan jarak dan kekuatan gempa tertentu dengan menggunakan gempa riwayat waktu. Pada studi ini telah dilakukan pengujian tiga bangunan di kota Semarang. Bangunan tersebut adalah Semarang Medical Center mewakili tanah lunak, Training Center II undip mewakili tanah sedang dan City One Hotel mewakili tanah keras. Gempa riwayat waktu yang digunakan berkuatan 6 – 7 Magnitude momen (Mw) dengan jarak yang bervariasi. Berdasarkan hasil studi ini maka dapat diketahui ketahanan suatu bangunan terhadap guncangan gempa dengan kekuatan 6 – 7 Mw dan jarak tertentu.
