Abstract

This integrated analysis explores real-world case examples and related data findings to gain a deeper understanding of the challenges and protection strategies needed to face these types of threats. The selected cases include the terrorist attack in Tokyo in 1995, the murder of Alexander Litvinenko in London in 2006, as well as the cyanide poisoning case in Jakarta in 2004. The data findings highlight the importance of developing rapid cyanide detection technology, personal protection equipment, coordinated emergency response, and effective law enforcement in protecting the public from cyanide exposure. Recommendations include investment in research and development of innovative protection technologies, development of standardized emergency response guidelines, and public outreach campaigns. With a holistic approach and cross-sector collaboration, it is hoped that we can increase preparedness and protect the community from the threat of chemical attacks involving cyanide.

Abstract

Stealth technology (teknologi siluman) merupakan salah satu teknologi yang sedang dikembangkan untuk menghilangkan jejak RADAR dari musuh. Spektrum yang digunakan dalam teknologi ini yaitu pada rentang gelombang mikro (8 – 12 GHz). RAM (Radar Absorbing Material) merupakan salah satu rekayasa yang dapat digunakan dalam perancangan teknologi siluman. Salah satu bahan yang berpotensi untuk dijadikan RAM adalah arang aktif sebagai bahan dielektrik. Dalam tulisan ini dilakukan studi komparatif terkait arang aktif dari beragam limbah biomassa, seperti jerami gandum, sekam padi, sekam, loofah, ampas tebu, kulit jeruk bali, kulit nangka, batok kelapa, dan semangka. Tiap arang aktif dari bahan baku berbeda akan mendapatkan nilai frekuensi dan daya serap yang berbeda. Sekam padi dan loofah merupakan limbah biomassa yang berpotensi untuk dijadikan sebagai RAM karena memiliki daya serap yang baik dan frekuensi yang sesuai dengan teknologi siluman ini.

Abstract

This study explores the use of porous carbon derived from palm kernel shells to adsorb lead ions (Pb2+) from water. Porous carbon was produced by carbonizing palm kernel shells at different temperatures (400, 600, and 800 °C) and was evaluated for its effectiveness in a lead chloride (PbCl2) solution. The best adsorption rate, reducing Pb2+ concentration by 27.5%, was observed by carbonized material at 800 °C with a 3 h contact time. Kinetic analysis suggested that the process followed a pseudo-second-order model, indicating that chemical adsorption was the dominant mechanism. The adsorption data were best described by the Freundlich isotherm, implying multilayer adsorption on an uneven surface. These findings highlight the efficient and low-cost potential of palm kernel shell-based porous carbon for removing heavy metals from wastewater. Palm kernel shell-derived porous carbon has proven to be a sustainable, cost-effective, and practical solution for mitigating Pb2+ contamination, positioning it as a promising candidate for environmentally friendly water treatment applications.

Abstract

This paper examines the application of nanofibers produced via electrospinning in the development of smart textiles for military clothing. Smart textiles represent a significant advancement, integrating functionality with comfort to enhance traditional military garments. This study explores the potential of smart textile technology to improve the efficiency and effectiveness of military operations through capabilities such as monitoring soldiers' physiological conditions, facilitating enhanced communication, and providing protection against environmental threats. A literature review methodology was employed to analyze existing research on smart textiles in the context of military applications. This review covers technological components, benefits, challenges, and the potential of nanofibers in military clothing. The results highlight the capacity of electrospun nanofibers to improve the protective, communicative, and adaptive properties of military wear, with a focus on materials like carbon nanotubes and graphene and their applications in enhancing tensile strength, conductivity, and UV protection. This paper contributes to a deeper understanding of smart textile technology and its potential to advance the defense industry and improve the quality of protective equipment for soldiers.
