Abstract

Indonesia has abundant natural resources, but if they are not optimized, they will end up as waste. Natural fibers come from plants, animals or minerals, standing out with certain advantages that differentiate them from artificial fibers. These advantages include the ability to decompose naturally (biodegradable), good strength and durability, and sustainable income through farming or capturing natural resources that produce fiber. The impact strength of composite materials combining natural fibers and synthetic fibers in ballistic material applications has grown rapidly. However, the use of synthetic fibers as reinforcement in composite materials has had a negative impact on the environment because they are difficult to decompose naturally and can cause long-term environmental disturbances. Therefore, utilizing natural fibers as reinforcement in composite materials is considered a good step. This update in research compares the characteristics of natural fibers in the use of ballistic materials. The natural fibers used are palm fiber, snake fruit midrib fiber, corn husk fiber, pineapple leaf fiber, water hyacinth fiber, hemp fiber. Ballistic material made from natural fibers

Abstract

Microstrip antennas play a crucial role in modern communication technology, with their performance dependent on shape and size. This study explores the impact of adding slots to hexagonal microstrip antenna radiation areas. The hexagonal shape was chosen due to its underexplored potential for slot additions. Slots act as elements influencing antenna radiation performance and altering characteristics. The research investigates the effects of various slot shapes and sizes (each with an area of 4 ) on hexagonal microstrip antennas at the initial frequency of 2.4 GHz. The importance of this study lies in the selected initial frequency, aligning with the micro-wave spectrum commonly used in wireless communication, radar, and telecommunications equipment. The hexagonal microstrip antenna, popular for its compact and efficient design, is relevant to modern communication devices.

Abstract

RAM or Radar Absorbent Material, is a substance designed to absorb radar or radio waves to prevent their reflection back toward the radar or enemy radar (Ishi et al. 2017). Extensive research has been conducted on RAM and its composition, particularly in the form of nanocomposites. To assess the effectiveness of a RAM's primary material, a key test is conducted to determine its electromagnetic wave absorption capability, known as the reflection loss test. This test quantifies a material's absorption ability, where a more negative reflection loss value indicates superior electromagnetic wave absorption. This literature review explores various nanocomposite materials and conductive polymers that can serve as the foundation for RAM. Notably, the PAni/Fe3O4 Nanocomposite emerges as the most efficient RAM material, boasting the lowest reflection loss at -53.7 dB.

Abstract

The optical glass used in LiDAR applications requires specific characteristics, including high strength and low porosity, to achieve optimal performance. One promising approach is the incorporation of alumina fibers as a reinforcement in the optical glass matrix. This research investigates the potential of alumina fibers in enhancing strength and reducing porosity in optical glass used in LiDAR applications. Alumina fibers are introduced into the optical glass matrix through a precise manufacturing process. The results of mechanical testing indicate that the addition of alumina fibers significantly increases the strength of the optical glass, making it more resistant to mechanical pressure that may occur during the use of LiDAR in challenging environments.

Abstract

The addition of titanium to steel materials has been a significant research focus in the metallurgical industry. This research aims to investigate the effect of titanium addition on the mechanical and structural properties of steel. Titanium is an interesting element in this context because it has properties that can improve the performance of steel, such as strength, corrosion resistance, and resistance to high temperatures. The addition of titanium to various types of steel has been shown to increase their strength and mechanical properties, primarily by forming titanium carbide or sulfide deposits that reduce grain growth and increase toughness and high temperature resistance. This could open up opportunities to develop high-strength steel with the addition of titanium for applications that require superior mechanical properties, such as for shielding defense equipment.

Abstract

Defense technology known as stealth technology aims to reduce the response of electromagnetic waves emitted by radar so that the position or location of an object is not detected. Barium Hexaferite has properties as a Radar Absorbing Material (RAM). Research on radar absorbing matrial from barium hexaferite already exists, but those using cu doping do not yet exist. In order to increase the effectiveness of its absorption, Barium Hexaferite is doped with Cu metal synthesized by coprecipitation method. Aniline polymerization was carried out with BaM to form BaM/PAni composite. Characterization of composite synthesis samples and coating results were carried out by SEM, FTIR, LCR-meter, and VNA to identify chemical bonds, electrical conductivity properties, microstructure, and reflection loss properties of RAM composite samples. Based on the results of previous research, the optimal absorption of multilayer coatings on steel with a reflection loss of -49.028 dB was obtained with an absorption frequency of 8.2 GHz. The addition of Cu doping is expected to improve the material's ability to absorb radar waves and reduce object reflections.

Abstract

Developments in the 21st century require the development of technology, one of which is construction material technology. The construction material generally used is conventional concrete on the market. However, in its use, conventional concrete is not environmentally friendly. Therefore, biomaterials were developed from the use of white oyster mushrooms with various media. This study of biomaterials develops mycelium using three types of media, namely rice husk waste, corn stalk waste and wood dust waste. The aim of this research is to obtain optimal media for the growth of white oyster mushrooms. The cellulose content of corn stalks, rice husks, and sawdust were 33%, 38%, and 41%, respectively. The research results showed that sawdust waste media was the best medium as a fungal growth medium. Wood dust waste with a cellulose content of 41% can produce the growth of mold as high as 8.62 cm. In rice husk waste media with a cellulose content of 38%, 5.62 cm was obtained. Then, on corn stalk waste media with a cellulose content of 33%, fungal growth was obtained as high as 0.632 cm
