"Para nelayan di Indonesia menghadapi tantangan utama dalam hal keselamatan ketika mereka pergi melaut. Untuk mengurangi risiko kecelakaan kapal, langkah yang dapat diambil adalah mendesain dan memperhitungkan stabilitas kapal dengan baik. Pada desain kapal ikan semi trimaran 5 GT, diperlukan kajian stabilitas untuk memastikan kestabilannya. Pengujian stabilitas dilakukan untuk mengevaluasi stabilitas kapal ikan semi trimaran 5 GT. Pada penelitian ini, fokusnya akan pada kajian stabilitas statis dari desain kapal ikan semi trimaran 5 GT. Dengan mengacu standar IMO MSC.267(85) IS Code 2008, semua kondisi pemuatan kapal ikan semi trimaran 5 GT model A telah lolos dan mematuhi semua kriteria IMO untuk stabilitas statis. Hasil uji ini menunjukkan kapal ikan semi trimaran 5 GT memiliki stabilitas yang baik dan dapat dilanjutkan untuk pengujian stabilitas lainnya.

Fishermen in Indonesia face significant safety challenges during their fishing expeditions, emphasizing the need to prioritize vessel stability to mitigate the risk of ship accidents. This scientific study focuses on the stability analysis of the semi trimaran 5 GT fishing vessel design. The objective is to assess the vessel's static stability through experimental and simulation methods. By adhering to the standards set by the International Maritime Organization (IMO) MSC.267(85) IS Code 2008, the intact stability criteria were used as a benchmark to evaluate the compliance of the semi trimaran 5 GT fishing vessel model A under various loading conditions. The findings of this study demonstrate that the vessel successfully meets all the IMO stability criteria, indicating its overall good stability. Consequently, the vessel can proceed with further stability testing to ensure safe and reliable operations."

"Emas merupakan komoditas logam yang dibutuhkan berbagai sektor industri, sehingga permintaan produksinya kian meningkat. Salah satu faktor yang perlu diperhatikan dalam pelaksanaan produksi emas di pertambangan terbuka adalah faktor keselamatan. Faktor keselamatan erat kaitannya dengan masalah kestabilan lereng, di mana keadaan lereng yang tidak stabil berpotensi mengakibatkan keruntuhan. Tujuan penelitian ini adalah untuk menganalisis kualitas massa batuan, tipe keruntuhan, dan kondisi kestabilan lereng pada setiap lereng tunggal di lokasi penelitian. Penelitian ini dimulai dengan pengambilan data yang meliputi orientasi bidang diskontinuitas, geometri lereng, sampel batuan, pengujian kuat tekan batuan, dan data sekunder lainnya. Data tersebut kemudian diintegrasikan dan diolah untuk mengetahui nilai kualitas massa batuan, analisis kinematika, dan analisis kestabilan lereng. Pengolahan data kestabilan lereng mengacu pada kerentanan lereng terhadap keruntuhan non-circular dilakukan melalui simulasi perangkat lunak Swedge, dan RocPlane. Hasil analisis menunjukkan bahwa kualitas massa batuan di daerah penelitian termasuk ke dalam kelas II (good rock). Tipe keruntuhan non-circular yang didapatkan melalui analisis kinematika menunjukkan bahwa keruntuhan baji berpotensi terjadi pada setiap lereng tunggal di lokasi penelitian. Potensi keruntuhan planar juga ditemukan pada lereng tunggal 2. Kestabilan lereng daerah penelitian menunjukkan kondisi stabil dan aman, dimana nilai faktor keamanan yang didapatkan bernilai lebih dari 1,3 (FK>1,3).

Gold is a metal commodity that is needed by various industrial sectors, so demand for its production is increasing. One factor that needs to be considered when implementing gold production in open-pit mining is the safety factor. The safety factor is closely related to the problem of slope stability, where an unstable slope has the potential to cause collapse. The aim of this research is to determine the quality of the rock mass, type of failure, and slope stability conditions on each single slope at the research location. This research began with data collection which included discontinuity plane orientation, slope geometry, rock samples, rock compressive strength testing, and other secondary data. The data is then integrated and processed to determine rock mass quality values, kinematic analysis and slope stability analysis. Processing of slope stability data which refers to the vulnerability of slopes to non-circular failure is carried out through Swedge and RocPlane software simulations. The analysis results show that the quality of the rock mass in the research area is included in class II (good rock). The non-circular failure type obtained through kinematic analysis shows that wedge failure has the potential to occur on every single slope at the research location. The potential for planar collapse was also found on single slope 2. The stability of the slope in the research area showed a stable and safe condition, where the safety factor value obtained was more than 1.3 (FK>1.3)."

"This book offers an essential introduction to the latest advances in delayed genetic regulatory networks (GRNs) and presents cutting-edge work on the analysis and design of delayed GRNs in which the system parameters are subject to uncertain, stochastic and/or parameter-varying changes. Specifically, the types examined include delayed switching GRNs, delayed stochastic GRNs, delayed reaction-diffusion GRNs, delayed discrete-time GRNs, etc. In addition, the solvability of stability analysis, control and estimation problems involving delayed GRNs are addressed in terms of linear matrix inequality or M-matrix tests."

"This book focuses on the applications of Equivalent-Small-Parameter Method (ESPM) in solving the steady-state periodic solutions, as well as stability analysis, of kinds of open-loop or closed-loop operated DC/DC converters, such as PWM, quasi-resonant and resonant ones. The analytical expressions of DC components and harmonics of state variables (inductor current and capacitor voltage) with DC/DC converters can be obtained by ESPM, which can be helpful to understand the nonlinear operating mechanism of switched-mode converters. It can also be useful for stability analysis and design for practical converters. Modeling and analysis on all kinds of DC/DC converters are introduced in detail in this book, along with a large amount of simulation or experimental waveforms to verify the correctness of the theoretical analysis based on ESPM."

"This book trains engineers and students in the practical application of machining dynamics, with a particular focus on milling. The book walks readers through the steps required to improve machining productivity through chatter avoidance and reduced surface location error, and covers in detail topics such as modal analysis (including experimental methods) to obtain the tool point frequency response function, descriptions of turning and milling, force modeling, time domain simulation, stability lobe diagram algorithms, surface location error calculation for milling, beam theory, and more. This new edition includes updates throughout the entire text, new exercises and examples, and a new chapter on machining tribology. It is a valuable resource for practicing manufacturing engineers and graduate students interested in learning how to improve machining productivity through consideration of the process dynamics."
