Abstract

Ilmu pengetahuan tentang prilaku suatu struktur bangunan sangat penting untuk memprediksi prilaku struktur tersebut sebelum dibangun. Hal ini untuk memastikan bahwa struktur tersebut aman digunakan. Teknologi modern sekarang ini mampu untuk memprediksikan prilaku suatu struktur dengan membuat simulasi computer sebagai pengganti hasil uji laboratorium. Meskipun demikian, hasil uji laboratorium perlu dilakukan untuk membenarkan model komputer yang disimulasikan. Tesis ini memperlihatkan perkiraan prilaku struktur komposit baja lempengan profil papan kering PSSDB (Profiled Steel Sheeting Dry Board) yang dibangun dari lempengan baja berprofil BONDEK II dan Papan Kering CEMBOARD, yang dihubungkan menggunakan baut ulir seft drill POWER DRIVE DX14. Struktur lantai ini menahan beban merata dan diteliti kelakuannya bagi berbagai ukuran lubang (lubang) ditengah panel, menggunakan perangkat lunak elemen hingga LUSAS-FE. Plat lantai bentang satu arah telah dianalisis pada penelitian ini. Hasil dari penelitian ini didapati bahwa lendutan pada arah longitudinal meningkat sebagai pengaruh dari keberedaan lubang daripada lendutan pada arah tranversal. Persentase rata-rata dari peningkatan lendutan dari plat dengan bentangan satu arah sebagai akibat dari lubang 20%, 40% dan 60% dari lebat plat tersebut adalah masing-masing 36%, 107% dan 185% dibandingkan dengan lendutan dari plat tanpa lubang. Dapat disimpulkan bahwa semakin besar ukuran lubang maka lendutan juga semakin meningkat.

Abstract

Generally, laboratory testing to determine the value of soil shear strength and stress path is triaxial test, especially for clay soil. In this research, the clay used for digital triaxial testing on axial compression (AC) stress path is Karawang clay soil, West Java, which have high plasticity (CH) in USCS classification. On pre-saturation process, a combination of vaccum and back pressure is used to speed up the saturation of the sample and to provide a high degree of saturation. Furthermore, the obtained soil parameters are used as inputs on finite element modeling which Mohr Coloumb and Hardening Soil model were used as the soil constitutive models. The results show that parameter optimization using hardening soil modeling has a behavior that is closer to the shape of the stress strain curve from laboratory tests.

Abstract

ABSTRACT Riau Province is one of the provinces that has several coastal areas, both in the mainland and the islands. The handling of many coastal locations in Riau Province is a problem for relevant agencies in making decisions about which coastal locations will be prioritized for handling. This study analyzes the level of coastal vulnerability and decision-making systems in terms of determining the priority of coastal areas to be handled using the Analytical Hierarchy Process (AHP) method. The results showed that Tanjung Motong beach, Kepulauan Meranti Regency and Coastal Pambang Beach in Bengkalis Regency were the highest vulnerability beaches with a value of 244.95. The criteria for strategic issues with sub-criteria for national strategic areas have the highest level of influence for determining the priority of coastal handling areas, which is 73%. Coastal Pambang Beach in Bengkalis Regency is a coastal area that is located in a national strategic area that gets priority handling.

Abstract

In construction concrete is the most widely used building material in the world, both in construction. Concrete is a composite building material made from a combination of aggregate and cement binder. The most common form of concrete is portland cement concrete, which consists of mineral aggregates (gravel, and sand), cement and water. Indonesia is the country with the 2nd largest plastic waste producer in the world on June 7, 2017, with data on the amount of plastic in the high seas of Indonesia reaching 0.48-1.29 million tons annually. Therefore, one way to cope with plastic waste, on this occasion the author tries to conduct an experiment about the Effect of Utilization of Bottled Plastic Waste as an Additional Material on Concrete Flexural Strength. This research was carried out by making concrete with the addition of alternative polymeric materials, namely plastic bottle waste (PET). The variation of the percentage of the addition of plastic bottle waste in this study is 0%, 2%, 3%, 5% of the mass of cement and concrete material used materials originating from Kampar Regency and Padang cement with the type of PCC (Portland Composite Cement). The results of the flexural strength test, obtained the quality of concrete has decreased, which in the mix of 3% decreased concrete quality is quite low from the mixture (0%, 2%, 3% & 5%), from 53.93 kg / cm2 in the mixture of 0% to 45.09 kg / cm2 in a mixture of 3%.
