Abstract

This study aimed to develop biodegradable Mg-6Zn hydroxyapatite (Mg-6Zn HAp) biocomposites for potential use in bone replacement applications. The hydroxyapatite (HAp) powders, sourced from cow bone, were synthesized through an eco-friendly and cost-effective process, leveraging bioresources for material sustainability. The Mg-6Zn and HAp powders were mechanically mixed through ball milling for six hours to ensure homogeneity. The resultant powder mixture was then subjected to isostatic pressing at a high pressure of 570 MPa, forming a dense coin-shaped composite with a 1.5 cm diameter. This coin was consolidated in a capsule furnace at elevated temperatures for one hour to enhance material integrity. The Mg-6Zn HAp alloy was thoroughly characterized using X-ray diffraction (XRD) to assess phase formation and crystallographic structure, and Scanning Electron Microscopy coupled with Energy Dispersive X-ray Spectroscopy (SEM-EDX) to examine microstructural features and elemental composition. For composite preparation, varying amounts of HAp (5%, 8%, and 12%) were incorporated into the Mg-6Zn matrix. SEM analyses revealed a uniform distribution of HAp particles along the boundaries of matrix particles, enhancing composite structure and stability. Results demonstrated that with an increase in HAp content, there was a corresponding improvement in the relative density and hardness of the composites. The corrosion rate decreased with higher HAp content, indicating improved biocompatibility and stability in physiological environments. This suggests that the Mg-6Zn HAp biocomposites, with their tailored microstructure and enhanced mechanical properties, hold promise for use in biodegradable bone replacement applications.

Abstract

Determining the optimal crystal structure is essential in the development of defense materials, as its crystal structure influences the physical and mechanical properties of a material. This study employs a mathematical approach to analyze crystal structures through three primary methods: Fourier Transformation, Direct Methods, and the Rietveld method. Fourier Transformation enables the analysis of diffraction data generated by the interaction of X-rays with atoms in a crystal, converting it into electron distribution to identify atomic positions. The Direct Method utilizes probabilistic phase relationships to accurately estimate atomic positions, even when diffraction data is incomplete. The Rietveld method, based on optimization, refines the crystal structure model by comparing experimental diffraction data with simulated results, minimizing differences between them. The analysis results show that the combination of these three methods effectively determines the optimal crystal structure. The implementation of these techniques is expected to support the selection of superior materials for defense applications

Abstract

This article analyses the nuclear energy policy model relevant to such countries as the United States of America, Russia, France and Japan. Moreover, this article also considers the international organizations, for example the International Atomic Energy Agency, as the supervising body in the field of nuclear energy programs and their security. The process of developing nuclear energy program must be well planned and must incorporate security, safety and environmental factors. Consequently, this nuclear energy policy must address all factors technical, economic, social-political and environmental factors underlying nuclear energy production.In this case, the IAEA and other international organizations contributing to stable and secure nuclear power usage are quite significant to the fulfillment of this requirement.great potential as an energy source that can reduce dependence on the use of fossil energy sources that are increasingly scarce and are often claimed to cause environmental damage. However, the use of nuclear energy also has risks that must be managed properly, such as nuclear accidents and the risk of terrorism. Several countries have developed their nuclear programs with the aim of meeting domestic energy needs and also as a national defense strategy. However, the development of this nuclear energy program also poses challenges in terms of security and safety. This article discusses the nuclear energy policy model that has been implemented in countries such as the United States, Russia, France, and Japan.

Abstract

This research was made to determine the effect of defense management on national interests using the mixed methods approach. Qualitative data are analyzed using NVivo 12, while quantitative data uses SEM-PLS 4 software to obtain robust and reliable findings. The results showed that defense management reengineering had a significant effect on the realization of national interests in overcoming separatists in Papua. Cronbach’s alpha and composite reliability values ​​that show high internal consistency. Average Variance Extracted (AVE) of more than 0.50, confirming the convergence of good indicators. The evaluation of the structural model shows a significant relationship between the engineering management of defense and national interests (the path coefficient = 0.661, p-value = 0.000), with an R-square value of 0.437, which shows moderate influence. NVivo 12 analysis reveals a major factor in strengthening national interests, including logistical readiness, interoperability between units, and local communities in handling separatism. However, there are limitations such as budget constraints, multidimensional threat complexity, and lack of cross-sector coordination that hamper optimal implementation. Importance-Performance Map Analysis (IPMA) shows that although engineering management of defense has a significant effect on national interests, its performance still needs to be improved. This study contributes originality by integrating SEM-PLS and NVivo to provide a holistic perspective and emphasize the need for more adaptive defense reengineering management to increase the effectiveness of defense strategies in dealing with separatist threats.

Abstract

Pada penelitian ini, dilakukan analisis untuk menemukan solusi atas masalah keterbatasan pasokan bahan bakar yang menghambat optimalisasi operasional kapal laut. Dalam konteks ini, energi nuklir dianggap sebagai alternatif yang menarik dan berkelanjutan, khususnya untuk sistem propulsi kapal laut TNI AL. Dengan mempertimbangkan berbagai klasifikasi dan pemilihan reaktor nuklir yang tersedia, penelitian ini menitikberatkan pada konsep teknologi reaktor nuklir yang cocok untuk kapal laut. Setelah melakukan studi literatur sehingga dapat di lihat bahwa dipilihlah reaktor nuklir tipe MSR (Molten Salt Reactor) sebagai solusi yang paling sesuai. Reaktor ini adalah jenis reaktor daya cepat pembiak modular kecil, menggunakan bahan bakar Thorium-Uranium233, dan berpendingin garam cair, sehingga dapat beroperasi pada tekanan rendah dan suhu sangat tinggi, minimal 33 MWth. Pilihan ini diharapkan mampu memberikan keamanan energi yang lebih baik, mengurangi ketergantungan pada pasokan bahan bakar fosil, serta memberikan keleluasaan dalam operasional kapal laut di masa depan. Meskipun demikian, pengembangan teknologi ini memerlukan pendekatan yang hati-hati dalam mengelola risiko terkait pengelolaan limbah radioaktif dan keamanan operasional.
