Abstract

Response of One Degree of Freedom System to Harmonic Loading on the structure idealized as single degree of freedom systems excited harmonically, that is structure subjected to force or displacement where the magnitude may be represented by a sine or cosine function of time. This type of excitation results one of the most important motions in the study of mechanical vibrations as well as in applications to structural dynamics. Structure is very often subjected to the dynamic action such cyclic load acting and resulting response due to the the unavoidable load eccentricity. The objective of the present study is to analyze the response of one-degree of freedom system to the portal 2D. The structure is modelled and analyzed using finite element method. The result obtained by FE method is joint displacement of the structure.

Abstract

The ultimate strength of the Very Large Crude Carrier (VLCC) is an important aspect that must be analyzed. The purpose of this study was to analyze the ultimate strength of the VLCC ship in terms of deformation under hogging and sagging conditions on the deck and bottom. Deformation is a change in the shape or size of a material due to a workforce that is applied to you. In this case, the deformation in question arises due to the working moment. This deformation analysis was carried out using the Non-Linear Finite Element Analysis (NLFEA) method. This analysis is carried out by presenting the support or Multi-Point Constraints (MPC) in the cross-section, as well as moments of 6.52 × 1012  for hogging conditions and -5.5 × 1012  for slack conditions.

Abstract

Indonesia is one of 193 countries committed to the sustainable development goals (SDGs). In this new paradigm of sustainable Indonesian development, the maritime sector is a priority for future development with the concept of blue economy, which is a sustainable ocean economy that produces economic and social benefits with the assurance of long-term environmental sustainability. The focus of the blue economy with this maritime economic strategy makes coastal communities the centre of blue economy growth. Makassar City has a coastal tourism area located in Tanjung Merdeka Village, Tamalate District Makassar, and is managed community-based by Non-Governmental Organizations (NGO) of Tanjung Merdeka. To maintain the sustainability process of coastal tourism area management, it is necessary to understand the concept of blue economy according to the maritime development strategy. Socialisation of the concept of blue economy in the development of coastal tourism areas in Makassar City has been carried out and achieved an increase in knowledge and understanding of participants by 50%. Understanding the concept of sustainable coastal and marine resource management, as well as how to participate in facing the challenges of environmental degradation and climate change, will complement the role of Tanjung Merdeka NGO as a tourism manager with the concept of blue economy. Assessment of the application of the concept of blue economy in coastal tourism areas has been carried out and fulfils the concept of blue economy according to Pauli's theory (2010).
