Abstract

Rocket flight tests invariably serve a purpose, one of which involves area monitoring or aerial photography. Consequently, the rocket necessitates the installation of a camera that remains consistently oriented toward the Earth's surface throughout its trajectory. Thus, ensuring the rocket's stability and preventing any rotation becomes imperative. To achieve this, the Onboard Attitude Determination Control System (OADCS) was researched and developed, fully controlled by NI myRIO with Labview as the programming language, ensures the rocket's attitude control and maintains a rolling angle of 0 degrees during flight. The MyRIO oversees the retrieval of attitude and position data from the X-Plane flight simulator, offering feedback through actuator control. The development of the OADCS proceeded incrementally through stages utilizing the Software in the Loop Simulation (SILS) and Hardware in the Loop Simulation (HILS) techniques, to ensure the verification of the system's functionality before its application to the rocket for real flight testing. In the OADCS control scheme, Model Predictive Control (MPC) is chosen, and it is compared with a PID controller to serve as a benchmark for processing speed. Because the rocket's flight time is short and its speeds of up to Mach 4. The simulation results indicate that MPC can halt the rocket's rotation 12 times more rapidly than PID control. Additionally, the MPC's ability to maintain a zero-degree rotation can persist throughout the rocket's flight time. Employing SILS and HILS enhances the OADCS rocket development process by incorporating MPC, which holds promise for application in real rockets.

Abstract

The leader is the center of the activity. There are many leadership styles, one of which is self-leadership. This leadership style will be applied in supporting Indonesia's national defence policy regarding its participation in mission activities to maintain world peace under the umbrella of the United Nations. Indonesia, which is one of the countries that contribute to the world peacekeeping force, will follow the dynamics and developments of the world, the ups and downs of policies at the United Nations make the State of Indonesia also have to follow the rhythm, the decrease in the number of peacekeepers or the completion of a mission will affect Indonesia's progress, so it takes a good leadership style and can be in line with world developments in the field of maintaining world peace, the difference in the need for troops according to the standards at the United Nations with the professional ability in preparing Indonesian troops is a separate discussion, for that we need a leader who can make decisions carefully and appropriate so that the ultimate goal of Indonesia's participation in world problems will be resolved if there is a leader who has a self-leadership leadership style, using the leadership theory.

Abstract

Modeling a high-speed flying vehicle is imperative to ensure the success of vehicle development missions. Moreover, adherence to research protocols mandates a stepwise approach to testing the vehicle model, encompassing simulation trials using software-in-the-loop simulation (SILS), hardware-in-the-loop simulation (HILS), as well as diverse ground and environmental tests prior to flight testing. This study entailed a collaborative effort between MATLAB/Simulink and LabVIEW to seamlessly integrate the model developed in MATLAB/Simulink into LabVIEW for the implementation of model predictive control (MPC) strategy, aimed at trajectory correction (TC) missions for the vehicle. This MPC strategy was directly applied to the onboard flight control system (OBFCS) of the vehicle. Simulation results indicate the successful control of roll and pitch conditions by OBFCS in both SILS and HILS, ensuring the maintenance of flight conditions in accordance with predicted trajectories despite the presence of simulated disturbances. Notably, the simulation demonstrates the independence or absence of interference between each simultaneous MPC control for roll and pitch adjustments.

Abstract

Background: Defense budgeting plays a critical role in shaping a nation's strategic and military capabilities, reflecting its global positioning and priorities. It is influenced by a complex intersection of global politics, security concerns, and economic factors. Understanding these dynamics is crucial for guiding national policies and strategies.Purpose: This study aims to analyze the intricate factors shaping military expenditures globally, with a focus on understanding the role of Gross Domestic Product (GDP) growth, geopolitical tensions, and international political dynamics.Design/methodology/approach: The research employs a systematic literature review (SLR) guided by the PRISMA protocol to synthesize insights from existing studies. Utilizes Scopus-indexed journals to ensure the quality and reliability of the literature.Findings/Results: The findings highlight GDP growth as a central determinant of military expenditure, influenced by geopolitical interdependencies and regional dynamics. Theoretical frameworks, such as "Realist Theory" and "Neoclassical Theory," frequently appear in the literature, emphasizing the interplay between economic and defense paradigms. Conclusion: Defense budgeting is shaped by multidimensional factors, requiring further research with broader data sources and regional focus.Originality/value (State of the art): This study provides a systematic synthesis of defense expenditure dynamics, bridging gaps in economic and geopolitical perspectives. Keywords: defense budget, military expenditure, Gross Domestic Product (GDP), defense economics, Systematic Literature Review (SLR)
