"Indonesia merupakan negara kepulauan terbesar di dunia. Peranan transportasi laut dan penyeberangan sangat dominan dalam memperlancar arus barang dan manusia. Akan tetapi, sejak dulu pemerintah Indonesia tetap menghadapi masalah transportasi yang sama, yaitu kemacetan kendaraan di area pelabuhan, terutama pada kondisi peak. Penelitian ini mencoba untuk mengidentifikasi perilaku sistem penyeberangan di pelabuhan Merak dengan merancang sebuah simulasi diskrit mengenai model antrian pelabuhan Merak saat ini pada berbagai skenario kondisi. Dari simulasi tersebut diketahui bahwa rata-rata waktu tunggu truk pada kondisi libur panjang mencapai 551 menit dan rata-rata waktu tunggu kendaraan pribadi pada kondisi lebaran mencapai 615 menit. Kemudian, dilakukanlah eksperimen-eksperimen terhadap model untuk menemukan solusi yang dapat meminimasir waktu tunggu penumpang tersebut. Hasil penelitian ini menyimpulkan bahwa dengan menambah satu buah dermaga, mengurangi headway kapal menjadi 12 menit, dan mengoperasikan 29 unit kapal roro, dapat mengurangi rata-rata waktu tunggu truk pada kondisi libur panjang menjadi 99 menit dan rata-rata waktu tunggu kendaraan pribadi pada kondisi lebaran menjadi 116 menit. Sehingga pembangunan Jembatan Selat Sunda (JSS) tidak perlu dilakukan.

Indonesia is the biggest archipelago country in the world. The role of sea transportation and ferries are really dominant in transporting goods and peoples around the country. But somehow, for decades, our government is still facing the same transportation problem, congestion, especially on peak season.

This research tries to identify the behavior of the ferry system at Port of Merak by designing a discrete-event simulation about the current queue model on several different scenarios.

Based on the simulation output, the average-time-in-system for trucks that go to the port on holiday is 551 minutes and the average-time-insystem for private vehicles that go to the port on Lebaran is 615 minutes. Then, several experiments are conducted on the simulation model in order to find a solution that could minimize those average-time-in-systems.

This research concludes that by building one more berth, decreasing the ship's headway to 12 minutes, and functioning 29 ships, it can reduce the truck's average-time-in-system to 99 minutes and the private vehicle's average-time-insystem to 116 minutes. So the Jembatan Selat Sunda (JSS) mega project is not necessary."

"This book reports on a comprehensive study addressing the dynamic responses of hydropower plants under diverse conditions and disturbances, and analyzes their stability and oscillations. Multiple models based on eight existing hydropower plants in Sweden and China were developed and used for simulations and theoretical analysis with various degrees of complexity and for different purposes, and compared with on-site measurements for validations. The book offers important insights into the understanding of the hydraulic, mechanical and electrical coupling mechanisms, up to market conditions and incentives. It recommends control strategies for a more stable and efficient operation of hydropower plants."

"This book presents a new approach for the analysis of chaotic behavior in non-linear dynamical systems, in which output can be represented in quaternion parametrization. It offers a new family of methods for the analysis of chaos in the quaternion domain along with extensive numerical experiments performed on human motion data and artificial data. All methods and algorithms are designed to allow detection of deterministic chaos behavior in quaternion data representing the rotation of a body in 3D space. This book is an excellent reference for engineers, researchers, and postgraduate students conducting research on human gait analysis, healthcare informatics, dynamical systems with deterministic chaos or time series analysis."

"IFToMM conferences have a history of success due to the various advances achieved in the field of rotor dynamics over the past three decades. These meetings have since become a leading global event, bringing together specialists from industry and academia to promote the exchange of knowledge, ideas, and information on the latest developments in the dynamics of rotating machinery. The scope of the conference is broad, including e.g. active components and vibration control, balancing, bearings, condition monitoring, dynamic analysis and stability, wind turbines and generators, electromechanical interactions in rotor dynamics and turbochargers. The proceedings are divided into four volumes. This second volume covers the following main topics: condition monitoring, fault diagnostics and prognostics; modal testing and identification; parametric and self-excitation in rotor dynamics; uncertainties, reliability and life predictions of rotating machinery; and torsional vibrations and geared systems dynamics.

"This book describes a systematic approach to risk assessment for complex socio-technical systems like industrial processes, especially innovative ones. It provides an overview of applications of system dynamics theory and methodologies on industrial systems in order to demonstrate the relevance of such an approach in helping to assess risks in such complex systems.An important feature of this approach is that it takes into account the dynamic of the interactions of the components (technical, human and organizational ones) in order to study and simulate the behavior of the system. This methodology helps to define the failures and/or accident scenarios and to implement and test the prevention and protection barriers."
