Abstract

Women are becoming more active in the defense industry. Since the morphology of the female body differs from that of the male during military activities, it is required to modify personal protection equipment to accommodate the female body shape. According to a literature review, a survey of a sample of female soldiers from different nations revealed that they felt the impacts of breast soreness when running, as well as a sense of "distorted breasts" and breathing difficulties. The woman's petite frame and the bulky, hefty bulletproof jacket both draw criticism for their respective dimensions. Using 3D design technology, a female mannequin with a 95B breast size was scanned in order to create a bullet-proof vest that is tailored to the contour of a woman's body. Changes in the breast's contour, which affect changes in the surface point parameters, result in adaptive breasts. Utilizing a combination of carbon fiber and 16% HGM epoxy, bullet-proof vests can be modified to provide lightweight dimensions and have the benefit of good ballistic resistance. This results in a material that is 20 mm for thick, 1,348 kg in weight, and capable of absorbing 348.27 Joules of energy from bullets. The results of this research are not optimal, so developments are needed in further research.

Abstract

According to the Central Statistics Agency of the DKI Jakarta Province, the number of motor vehicles in DKI Jakarta in 2021 reached 21,758,695 units, with motorcycles dominating at 16 million. With a land area of 64.5 km2, traffic congestion is inevitable. Because of this condition, this study proposes a mass transportation means that can pass through land and water, namely the Amphibious Bus. When in water, the most important part of a ship is the hull. Some requirements that must be met to design a ship's hull include being lightweight, corrosion-resistant, fire-resistant, and safe and comfortable for passengers. Several materials are considered as materials for amphibious buses, namely low carbon steel, alumunium, Fiberglass Reinforced Plastic, Stainless Steel. From the AHP comparison, low carbon steel and FRP have advantages in compressive strength, tensile strength, and bending strength compared to other materials. Meanwhile, aluminum has the advantage of corrosion resistance compared to other materials.

Abstract

The need to develop protective systems to protect against attacks from various sources is increasingly becoming a personal, social and national security issue. To develop innovative armor systems, it is necessary to monitor the developments made on the types, technology and performance of threats (weapons, projectiles, explosives, etc.) In particular, the use of helmets of a high level of protection on the battlefield is essential. Therefore, the development of evaluation methods that can predict injury and trauma is very important. However, the risk of injury or trauma that may result from induced acceleration is an additional consideration. To develop new materials and layouts for helmets, it is necessary to study the impacts caused by ballistic impacts on the human head in various scenarios. Composite materials in military applications have proven to be superior to metal materials, in increasing the mobility of Force personnel. The use of composite materials in military helmets is very important in relation to the speed of incoming bullets, one of which is made from thermoplastic and thermoset polymers. Particle composite material composed of Bisphenol A epoxy resin matrix and reinforcement in the form of Javanese jute fiber which is applied to bulletproof helmets. When using this composite, you can determine the number of sheets of Javanese jute fiber that is effective against the force of the bullet fired, this is to support the safety of its use.

Abstract

Currently, the development of science and technology is developing very quickly. One technology that is currently developing rapidly is unmanned aerial vehicles (UAV). This technology is believed to be a new breakthrough in the modern era because it minimizes human involvement in its operation. This increases effectiveness and reduces risk management in the operational field. Especially in the vast territory of the Unitary State of the Republic of Indonesia with diverse natural landscapes, UAV are considered very helpful as a means of defense and security equipment (alpahankam) in espionage. With these geographical conditions, to carry out its mission, a UAV requires a battery as the driving force. However, in general, the most widely used battery is the lithium-ion (Li-ion) type. It is known that there are several problems with Li-ion batteries, including not being able to withstand heat, being prone to exploding, and if the battery has a large capacity, the size of the battery must be large. Considering this situation, a study is needed to examine several alternative types of batteries, namely: lithium-air (Li-air) and lithium-sulfur (Li-S) batteries. This article aims to compare the performance of lithium-air batteries, and lithium-sulfur batteries which can later replace the use of lithium-ion batteries which are currently widely used in UAVs. The method used in writing this article is Systematic Literature Review (SLR) by searching, collecting and evaluating several sources related to the research object. From a comparison of the three batteries, Li-S batteries offer a large specific energy compared to Li-air and Li-ion batteries. Li-S batteries are currently receiving more attention so they are expected to move towards mass use more quickly. The results of this literature are that Li-S batteries have an energy density of 2,500Wh/kg and have exceeded the energy density of Li-ion batteries of 890Wh/kg and Li-air batteries of 250-1,200Wh/kg. Energy density determines how much energy can be accommodated in a cell of the same size. Thus, it is hoped that Li-S batteries will be a solution to problems with UAV batteries.

Abstract

This research examines the effectiveness of bulletproof vests made with composite materials, focusing on carbon fiber. The study finds that the thickness of the carbon fiber and the HGM plastic coating in the vest are crucial factors in enhancing protection against bullet penetration. In some instances, thicker composite materials offer better defense. Furthermore, the use of composites allows for lightweight vests, reducing the physical strain on the wearer. These findings have significant implications for the development of personal protective equipment in various sectors, such as the military, law enforcement, and industries like construction. Enhancing the efficacy of bulletproof vests through the integration of composite materials is a vital stride in enhancing the safety of individuals encountering potential bullet threats.
