Abstract

Earthquakes from 2004 to 2009 in Indonesia has resulted in many deaths and the collapse of the building. The American Society of Civil Engineers (ASCE) with the Federal Emergency Management Agency (FEMA) has published FEMA 310 as a handbook for seismic evaluation of buildings. FEMA 310 evaluation includes evaluation of phase one, two and three. Evaluation of phase one (tier 1) using a checklist of structural, non-structural, region of low sismicity and also geologic site hazard and foundation. Evaluation of the second phase (tier 2) is a linear analysis for structures such as static equivalence analysis and dynamic. Evaluation of the third stage (tier 3) is non- linear analysis of such a pushover. If the evaluation phase of the assessment does not meet the criteria, then it should proceed to the second phase, as well as for further evaluation. The building is located in the city of Pekanbaru that is reviewed and evaluated up to the second phase. Calculation of seismic shear force have used seismic hazard map of Indonesia has been published in 2010. This is one step to improve the performance of structures to resist earthquakes, it is expected that this will reduce structural damage and avoid loss of life. The results of the evaluation phase one (tier 1) that has been conducted shows that the buildings that were reviewed non- compliant for weak story and soft story. Evaluation of the second phase (tier 2) shows that all the columns in buildings were able to bear the load, while some beam were over strength, however both of building can be declared the buildings are safe against earthquakes (compliant).Keywords : Earthquake, FEMA 310, quick assessment, seismic evaluation

Abstract

The increasing number of population and the development of Bengkalis Island area that happens every year, give effect to the improvement of water requirement. It causes problem of imbalance between the availability and requirement of water. Therefore, water balance analysis in Bengkalis Island become an interesting thing to be studied. The water availability can be calculated using the Mock method or Nreca method. Water availability is calculated under several conditions, such as: dry (Q80%), normal (Qaverage) and wet (Q20%). While the water requirement is calculated based on domestic water requirement and non-domestic requirement. The water balance analysis calculated based on dry conditions (Q80%) can be concluded with a water surplus, only at the time of August period 2 which experienced deficit of 1,481 m3/sec . As for wet conditions (Q20%) and normal conditions (Qaverage) will be surplus for the next 20 years. Keywords: water availability, water requirement, water balance, Mock method, Nreca method

Abstract

Gempa adalah pergeseran tiba-tiba dari lapisan tanah di bawah permukaan bumi. Ketikapergeseran ini terjadi, timbul getaran yang disebut gelombang seismik. Ketika terjadi gempa,struktur akan mengalami perpindahan secara vertikal dan horizontal. Gaya gempa arah vertikaljarang mengakibatkan keruntuhan struktur, namun gaya gempa arah horizontal akanmenyebabkan keruntuhan karena gaya ini bekerja pada titik–titik lemah struktur.Rapid Visual Screening (RVS) adalah metode identifikasi suatu bangunan secara cepat tanpaharus menganalisa bangunan dengan menggunakan software. Untuk mengidentifikasi tingkatrisiko suatu bangunan terhadap ancaman gempa bumi, bisa dilakukan dengan RVS pada tahappermulaannya. Kemudian hasil dari RVS bisa menentukan apakah gedung yang di evaluasitersebut berisiko atau tidak, kalau berersiko maka akan dilanjutkan ke evaluasi FEMAberikutnya.Gedung yang mempunyai tidak mempunyai resiko yaitu gedung Rusunawa dan RektoratUniversitas Riau (UR), sedangkan gedung yang harus dilanjutkan untuk dievaluasi denganFEMA lanjutan adalah gedung Faklutas Pertanian (FAPERTA) UR. Gedung FAPERTA URdikatagorikan beresiko karena gedung FAPERTA UR memiliki komponen FEMA 154 yangmenjadi faktor pengurang dari nilai basic score, seperti vertical irregularity, plan irregularitydan tipe tanah.Kata kunci: FEMA 154, Gempa, Rapid Visual Screening

Abstract

Least square is a method of tidal harmonic analysis that ignores meteorological factors in analyzing and predicting tidal elevations. This study analyzes the accuracy of tidal elevation predictions based on the initial date of the simulation. The analysis used 15 days tidal data from Pelindo Port C, Dumai. Furthermore, the results of the study were compared with the results of the most recent study, namely predictions of tide admiralty 15 days in the same location. The results of this study indicate that the results of the 15 days least square method prediction are more accurate than the admiralty method. The RMSE value from the least square method calculation gives the smallest Root Mean Square (RMSE) value of 34,56 cm, while the admiralty method is 71,38 cm. The most appropriate time to take primary data in the field for the purposes of tidal predictions is at the beginning of the third week of each month in the hijri calender or when the half moon phase.Keywords : least square method, tidal prediction, RMSE
