Abstract

Indonesia is a country that has a high seismic risk, so that the high-level buildings need to be designed to resist earthquake loads. Modeling of buildings generally use three-dimensional program. The designers usually model beams and columns as elements of the line and the rest, which were slab, shear wall and stairs modeled as two-dimensional elements or shell elements. Modelling stairs using shell elements can rigidify building. When structural elements in buildings are designed based on these conditions, it will be more vulnerable under seismic load. In this paper, it will be examined on effect of stair in buildings under earthquake load. The parameters that will be studied are building’s natural period, displacement between floors, and seismic forces that occur in the building. From this research, it is known that modeling without stairs will create a larger building’s natural period and displacement between floor so that modeling without stairs will make more conservative design structures against earthquake loads.

Abstract

Dalam suatu pembangunan proyek konstruksi hampir selalu dipastikan terdapat permasalahan yang dapat menimbulkan keterlambatan dan pemborosan waktu. Baik dari proses perencanaan, pengadaan hingga proses instalasi akan dihadapkan pada berbagai permasalahan teknis dan nonteknis yang harus dapat diminimalisir dengan sebaik-baiknya oleh semua pihak dalam proyek konstruksi. Pekerja pada proyek konstruksi seperti Kontraktor Utama dan Kontraktor SUB merupakan pekerja yang sering menghadapi masalah langsung dalam proyek konstruksi. Begitu pula pada proyek pembangunan Turbine Hall di PLTU Tambak Lorok Blok 3 Semarang ditemukan beberapa kendala yang menjadi faktor keterlambatan dan pemborosan waktu. Penelitian ini dilakukan untuk mengetahui faktor-faktor penyebab keterlambatan dan pemborosan waktu menurut beberapa elemen pekerja kontraktor utama dan sub kontraktor yang mengerjakan proyek dengan cara penyebaran kuisioner. Hasil yang diperoleh dari kedua elemen pekerja tersebut kemudian dianalisis menggunakan analisis deskriptif dengan SPSS untuk penyebab keterlambatan dan analisis dengan metode Borda untuk faktor penyebab waste time. Dari faktor-faktor penyebab keterlambatan dan pemborosan waktu yang didapat dari beberapa elemen pekerja, akan dilakukan analisis perangkingan dan diketahui faktor-faktor utama.In a construction project development is almost always sure to always have problems that can cause delay and waste time. Both of the planning process, procurement even until the installation process will be faced with various technical and nontechnical problems that must be able to be minimized as well as possible by all sides of the construction project. Workers in construction projects such as Main contractors and SUB contractors are workers who often face problems directly in the construction project. Similarly, the Turbine Hall construction project at PLTU Tambak Lorok Block 3 Semarang was found in the project a few obstacles which became a factor of delay and waste time. This research was conducted to determine the factors of the cause of delays and waste time according to some elements of the workers ' main contractors and sub-contractors working on the project by the dissemination of the questionnaire. The results obtained from all two elements of the worker are then analyzed using the descriptive analysis with SPSS for the cause of delays and analysis by Borda method to cause waste time factors. From the factors that cause delays and waste time gained from some elements of the worker, there will be a ranking analysis and known major factors.

Abstract

Sistem struktur dalam dunia konstruksi bangunan gedung bertingkat memiliki banyak metode dan system struktur oleh karena itu perencana harus memilih sistem struktur yang sesuai dengan kebutuhannya. Pada proyek Jogja Apartment digunakan sistem flat slab-drop panel, sistem pelat tersebut masih jarang digunakan dalam perancanaan gedung. Penelitian ini dilakukan untuk membandingkan antara sistem flat slab-drop panel dan sistem pelat-balok yang ditinjau dari segi biaya pelaksanaan, waktu pelaksanaan, dan desain strukturnya. Penelitian dilakukan dengan cara mendesain ulang satu denah pelat gedung Jogja Apartment dengan menggunakan sistem flat slab-drop panel dan sistem pelat-balok dengan metode dan pembebanan yang sama. Metode yang digunakan dalam mendesain kedua sistem pelat tersebut adalah metode desain langsung dengan peraturan SNI 03-2847-2013 sebagai dasar perhitungannya. Dari hasil penelitian didapat bahwa sistem flat slab-drop panel memiliki biaya sebesar Rp3.552.429.292 lebih murah 24,52% dibandingkan menggunakan sistem pelat-balok sebesar Rp4.706.334.233. Untuk waktu pelaksanaan sistem flat slab-drop panel memiliki waktu lebih cepat 2 hari dibandingkan dengan sistem pelat-balok. Sistem flat slab-drop panel memiliki tinggi ruang bebas yang lebih tinggi dibandingkan dengan sistem pelat-balokMany types of structural systems in the construction world of a multi-storey building make planners choose a structural system that suits their needs. Jogja Apartment project used a flat slab-drop panel system. It is rarely used in building planning so this study conducted to compare the flat slab-drop panel system and the plate-beam system in terms of implementation costs, implementation time, and structural design. The study was conducted by redesigning one plate layout of the Jogja Apartment building by using the flat slab-drop panel system and the plate-beam system using the same method and loading. The method used in designing the two plate systems is a direct design method based on SNI 03-2847-2013. This study found that the flat slab-drop panel system has a cost of Rp 3.552.429.292, it is 24,52% cheaper than using a plate-beam system (Rp 4.706.334.233). The flat slab-drop panel has a faster time of 2 days to build compared to the plate-beam system in the implementation time. The flat slab-drop panel system has a higher free space compared to the plate-beam system in structural design.
