Abstract

The use of conventional plastic in the manufacture of Indonesian National Army (TNI) ration packaging has become an unavoidable standard because it provides strength, resilience and durability which is very important for protecting food and other materials. However, the use of conventional plastic in making ration packaging has become an increasingly pressing problem, especially regarding environmental sustainability. To overcome this problem, conventional plastic must be replaced with environmentally friendly plastic (biodegradable plastic). The method used is a literature review by comparing the Indonesian National Standards with literature from various journals. The results of literature research show that there is no biodegradable plastic that meets SNI 7818:2014. The mechanical properties and biodegradability of biodegradable plastics are influenced by the concentration of additives such as plasticizers and fillers, such as glycerol and chitosan.

Abstract

The Single Photon Detector is employed in quantum computing, sensing, and communication technologies. NbRe, a superconductor, exhibits lower noise, energy gap, and minimum energy compared to silicon, resulting in higher sensitivity. NbRe can be found in the form of microstrips and nanostrips. Based on the data, NbRe with a microstrip cross-sectional area will have higher sensitivity and efficiency than NbRe with a nanostrip cross-sectional area. This is because the critical temperature (Tc), minimum energy (Emin), and thickness of NbRe microstrip are smaller than those of nanostrip, while its critical current density is larger. Based on literature review and calculations, it is determined that NbRe microstrip has Tc = 3.08 - 5.23K, Jc = 15.5x10^9 A/m², Emin = 0.017 eV, and a thickness of only 4 nm. In contrast, NbRe nanostrip has Tc = 6.77 K, Jc = 5x10^9 A/m², Emin = 0.28 eV, and a thickness of approximately 14.4 nm.

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

ABSTRACT  Radar systems detect objects using electronic signals. Radar Absorbing Material (RAM), especially graphene, increases radar wave absorption. Using coconut waste to make Graphene Oxide (GO) supports sustainability. It advances more efficient and sustainable radar wave absorption technology. This research is based on literary analysis. The method used in this research is a literature review and in this study will compare the reflection loss material graphene oxide as a radar absorber with other materials.  This research shows that GO synthesized with the Hummer method at 400°C has the best performance in radar wave absorption, competing with other materials such as CoTi1-xCexO3 and silicone rubber variations. This makes GO an attractive choice for radar wave absorption applications, especially on microwave frequencies.Keywords:Absorber Radar, Graphene Oxide, Coconut Waste, Hummer Method

Abstract

This research discusses the use of oil palm fiber as a base material for composites intended for sound insulation purposes. Sound insulation materials play a key role in reducing noise levels in various environments. Oil palm fiber is identified as a promising material for the effective and sustainable production of sound insulation materials. Test results indicate that the composite of oil palm husk demonstrates the highest sound absorption coefficient (α) at both standard and high frequencies. Consequently, the fiber from oil palm empty fruit bunches (EFB) can be utilized as a viable material for sound insulation composites, and further research can be conducted on the fiber materials from oil palm empty fruit bunches (EFB).

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

Radar is a crucial tool in military applications for detecting enemy objects in its vicinity, but its presence can pose a risk of being detected by adversaries. Therefore, this research focuses on the development of Radar Absorbing Material (RAM) using activated carbon obtained from cassava peel and Barium M-Hexaferrite. The research results indicate that this combination can be used as a protective layer on military drones made of composite hemp fibers, enhancing the drone's ability to absorb radar waves, thus reducing the risk of detection by adversaries. This improves the effectiveness of military operations and contributes to environmental preservation through the use of eco-friendly materials.
