"Over the past 40 years the field of molecular simulations has evolved from picosecond studies of isolated macromolecules in vacuum to studies of complex, chemically heterogeneous biological systems consisting of millions of atoms, with the simulation time scales spanning up to milliseconds. In Biomolecular Simulations: Methods and Protocols, expert researchers illustrate many of the methods commonly used in molecular modelling of biological systems, including methods for electronic structure calculations, classical molecular dynamics simulations and coarse-grained techniques. A selection of advanced techniques and recent methodological developments, which rarely find coverage in traditional textbooks, is also introduced. Written in the highly successful Methods in Molecular Biology series format, chapters include general introductions to well-established computational methodologies, applications to real-world biological systems, as well as practical tips and general protocols on carrying out biomolecular simulations. Special emphasis is placed on simulations of proteins, lipids, nucleic acids, and carbohydrates. Authoritative and practical, Biomolecular Simulations: Methods and Protocols seeks to aid scientists in further simulation studies of biological systems."

"Energi tidak terbarukan di Indonesia seperti batu bara masih sangat banyak digunakan untuk menghasilkan listrik. Energi tidak terbarukan ini dapat digantikan oleh sumber energi terbarukan. Indonesia sebagai negara kepulauan mempunyai banyak potensi energi terbarukan di laut seperti energi arus pasang surut. Energi ini dapat diubah dari bentuk energi kinetik menjadi energi listrik menggunakan turbin arus. Salah satu daerah yang mempunyai potensi cukup besar untuk pemanfaatan arus laut ini adalah Selat Alas yang memisahkan Pulau Lombok dengan Pulau Sumbawa. Pemilihan Selat Alas ini dikarenakan letaknya yang berada diantara dua pulau yang cukup kecil sehingga dapat bermanfaat bagi kedua pulau tersebut. Studi ini bertujuan untuk mengetahui besaran efisiensi dari turbin arus yang disimulasikan secara numerik menggunakan keadaan yang ada pada Selat Alas. Dalam studi ini dilakukan variasi diameter 18, 20, dan 22 meter. Berdasarkan hasil studi, dapat disimpulkan bahwa diameter turbin terbaik yang diperoleh secara numerikal adalah diameter turbin 22 meter dengan memperoleh efisiensi sebesar 42,58%.

Non renewable energy in Indonesia like coal still very widely used to generate electricity. This non renewable energy can be replaced by renewable energy sources. Indonesia as an archipelagic country  has a lot renewable enrgy sources potential in the sea such as tidal power. This energy can converted from kinetic energy to electrical energy using tidal turbine. One of the area with the biggest potential is Alas Strait. Alas Strait separate Lombok Island and Sumbawa Island. The selection of this area is based on because this strait separate two small islands so the electricity that generated by this turbine can be useful for the people of this two islands. This study aims to analize the efficiency of tidal turbine simulated with the condition of the Alas Strait using numerical simulation. In this study, variatios in diameters of the turbines are 18, 20, and 22 meters. Based on all the results of the tidal turbine efficiency study, it can be concluded that the best diameter of the turbine is 22 meters, with the efficiency generated is 42,58%."
