Abstract

Tugas utama dari proyek ini adalah untuk mendesain “kepala” dari breakwater (pe- mecah gelombang) sebelah utara bersama-sama dengan bagian “belalai” breakwater. Tujuan dari perencanaan ini adalah untuk mendapatkan breakwater yang dapat ber-tahan pada kondisi gelombang harian dan ekstrim (badai). Sedangkan tujuan lainnya adalah untuk menyediakan alur masuk pelayaran yang tenang ke kolam pelabuhan. Tetapi untuk kondisi tertentu, kapal-kapal tidak dapat berlabuh di pelabuhan karena kriteria dari akhir perencanaan adalah struktur yang dapat/menerima limpasan (over-topping) yang cukup besar. Kondisi ini didefinisikan sebagai maksimum gelombang transmisi adalah kurang dari 1 m dalam periode ulang kejadian 50 tahunan.

Abstract

This research aimed to investigate effect of using nano materials rice husk ash and superplasticizer admixture to concrete compressive strength. Nano rice husk ash used as subtitute of pozzolan portland cement. Production of nano rice husk ash use Planetary Ball Milling with  duration of  milling  for 1 hour. To determine effect of using nano materials rice husk ash dan superplasticizer admixture used variation percentage of materials nano rice husk ash such ash 5%, 10%, and 15% with or without superplasticizer admixture. Tests were conducted  at 28 days with uniaxial loading (one-way). Result of this research indicate normal concrete without substitution of nano rice husk ash and without superplasticizer have highest of concrete compressive strength. Concrete with rice husk ash decreased in compressive strength because of rice husk ash absorb much water and increase the length of  hydration process of cement in concrete mix. Although there is a decrease through this research is expected, nano techonology in civil engineering can more developed.

Abstract

Design of highrise building includes design of structure elements such as floor slabs, stairs, beam-column frames and foundations to withstand all working loads. Therefore, an engineer should select the most appropriate structural system such as fully elastic, partially ductile or fully ductile. The structure of Horison Hotel Pekalongan is designed to apply Special Moment Resisting Frame System (SRPMK) based on Indonesia building codes and standard. The structure analysis was conducted using ETABS v.9.7.1 software. The seismic analysis using the response spectrum dynamic analysis obtained the value of maximum vibration period of 1.74 seconds and design seismic force (V) = 344.18 ton. The internal forces calculated from ETABS v.9.7.1 were used to determine the amount of reinforcement required by the structure. Results obtained from the design show that Special Moment Resisting Frame System (SRPMK) used in Horison Hotel Pekalongan is capable of supporting all working loads considered in the analysis.

Abstract

Box girder bridge in Indonesia, including new. The intent and purpose of this thesis is to plan the bridge box girder structure. Where bridges with spans plan along 310 m with 2 pillars and different pillar heights. Because there are differences in the height of this bridge inspected by stiffnes balance method to locate deviation and shakes the same time so strong pillar and not collapse. Planning earthquake loads based on the latest regulations (SNI 03-2833-2008 Earthquake Resistance Evaluation Standards for Bridge). Analysis of bridge structures using SAP program. The bottom structure which includes abutment and foundation broom method to determine the shear boundary. The conclusion that can be drawn is necessary to balance stiffnes to know the exact dimensions of the pillars of that bridge is on it can stand firmly. Plastic hinge to determine the maximum acceptable shear pillar and foundation to determine the shear foundation failure not to occur, which can lead to the destruction of the structure.
