Abstract

In this increasingly modern era, innovation in the main tool of the defense system (defense equipment) is the main support in the process of maintaining the sovereignty of the Unitary State of the Republic of Indonesia (NKRI). One of them is the innovation applied to TNI uniforms using electrochromic-based materials, namely PEDOT: PSS. PEDOT:PSS is known to be included in the classification of conductive polymers which have relatively good compatibility in terms of physical and chemical. The application of PEDOT:PSS as smart military textiles is carried out through a three-dimensional (3D) fabrication method, namely die-coating and ink-jet printing with a fabrication process speed of 20 meters per minute. Both of these methods are capable of producing high quality products, easy to design, and able to control the thickness of the substrate in the range of 80 to 750 nm

Abstract

The turbine exhaust system is a critical component in maintaining the structural integrity and airworthiness of turbofan-powered transport aircraft on CFM56-7B engines, the Federal Aviation Administration (FAA) issued Airworthiness Directive (AD) 2025-04-03, requiring the modification of the engine primary exhaust nozzle to prevent potential separation and structural damage to the fuselage. This study evaluates the implementation of the directive in the Sriwijaya Air fleet under the scope of Boeing Special Attention Requirements Bulletin 737-78-1106 RB Revision 1. The research method combines airworthiness compliance analysis, engineering inspection, and procedural verification using the Accomplishment Instructions defined in EO M-78-003. The modification involved the installation of TOP KIT 002A0123-1 for Off-Wing Rework Kit and 002A0123-2 for On-Wing Installation Kit, the replacement of affected part numbers 314A2610-1, -62, -68, and incorporation of Airworthiness Limitations (AWLs) Nos. 2, 3, and 4 into the operator’s maintenance program. The results confirm that the affected aircraft—registrations PK-CRI, PK-CRA, PK-CRE, and PK-CRH—belong to Group 1 configuration and require mandatory action within 90 days after the AD effective date April 8, 2025, and must be inspection completed before July 31, 2028.

Abstract

Kebutuhan akan material pelindung dengan rasio kekuatan terhadap berat yang tinggi semakin meningkat seiring dengan tuntutan mobilitas dan efisiensi sistem pertahanan modern. High Entropy Alloys (HEAs), sebagai kelas material logam multikomponen berbasis multi-principal elements, menawarkan pendekatan nonkonvensional dalam desain paduan yang berpotensi melampaui performa baja armor konvensional. Studi ini meninjau secara komprehensif perkembangan terbaru mengenai sifat mekanik, perilaku deformasi dinamis, dan ketahanan benturan balistik dari berbagai sistem HEAs. Melalui pendekatan systematic literature review, artikel ini mengidentifikasi empat efek inti HEAs seperti entropi tinggi, distorsi kisi, difusi lambat, dan efek koktail sebagai faktor fundamental yang menghasilkan kombinasi luar biasa antara kekuatan, keuletan, dan ketangguhan. Dibandingkan dengan lapis baja seperti Ramor 550 dan Armox 500T yang memiliki kekuatan spesifik (specific strength) 159–208 MPa·g/cm³, beberapa HEAs (misalnya AlCuFeMnMgTi) menunjukkan nilai hingga >500 MPa·g/cm³ dengan kekerasan mencapai 770 HV. Temuan ini menunjukkan bahwa HEAs mampu mencapai efisiensi struktural dan ketahanan deformasi lebih tinggi pada densitas yang lebih rendah, menjadikannya kandidat unggul untuk aplikasi armor ringan berperforma tinggi. Tantangan utama yang diidentifikasi meliputi optimasi komposisi, kontrol mikrostruktur selama pemrosesan, serta isu biaya dan skalabilitas manufaktur. Kajian ini menegaskan bahwa dengan integrasi antara desain berbasis komputasi, powder metallurgy, dan arsitektur material berlapis atau hibrida, HEAs berpotensi menjadi material strategis dalam pengembangan lapis baja generasi mendatang yang ringan, tangguh, dan adaptif terhadap ancaman balistik modern.

Abstract

Gamma radiation emitted by the Cobalt-60 (⁶⁰Co) isotope is a high-energy ionizing radiation source widely employed in various applications. The gamma photons produced, with energies ranging from 1.17 MeV to 1.33 MeV, possess a high penetrating capability; consequently, the selection of an appropriate shielding material is critical to ensuring radiation safety and protection. Previous experimental studies have largely focused on lead (Pb) as the primary shielding material, which is nevertheless limited by its toxicity and the relatively high cost of its handling and disposal, thereby motivating the search for safer and more economical alternatives. However, systematic comparisons of the shielding effectiveness of several candidate materials against ⁶⁰Co gamma radiation under controlled thickness and testing conditions remain limited. This study therefore aims to determine and compare the Linear Attenuation Coefficient (LAC) of several selected materials and to evaluate their effectiveness as gamma radiation shields. The method employed involves experimental measurement of radiation intensity using a calibrated detector after transmission through samples of varying material composition; the resulting data are subsequently analyzed using the Beer–Lambert law to calculate the attenuation coefficient of each material.
