Abstract

Robotic technology has become a critical component in modern military operations due to its ability to enhance operational effectiveness, improve battlefield awareness, and reduce risks to human personnel. The rapid advancement of artificial intelligence, autonomous systems, sensor technologies, and communication networks has significantly expanded the capabilities of military robots across land, air, surface, and underwater domains. This study examines the role of robotic technology in supporting combat operations, focusing on its applications in intelligence, surveillance, reconnaissance (ISR), force protection, logistics support, target acquisition, urban warfare, and electronic warfare. Military robotic systems, including Unmanned Ground Vehicles (UGVs), Unmanned Aerial Vehicles (UAVs), Unmanned Surface Vehicles (USVs), and Unmanned Underwater Vehicles (UUVs), provide enhanced operational flexibility and enable missions in hazardous environments where human deployment would be highly risky. Furthermore, the integration of artificial intelligence enables autonomous navigation, target recognition, sensor fusion, and real-time decision support, thereby improving mission efficiency and accuracy. The study also discusses key advantages of military robotics, including casualty reduction, increased mission endurance, and force multiplication capabilities. However, several challenges remain, such as cybersecurity vulnerabilities, communication disruptions, limited autonomy, energy constraints, and ethical concerns regarding autonomous weapon systems. Future developments are expected to focus on swarm robotics, human-robot teaming, AI-driven autonomy, multi-domain operations, and advanced energy systems. The findings indicate that robotic technology will continue to play an increasingly significant role in shaping future warfare by enhancing military capabilities while minimizing operational risks and human casualties.

Abstract

This study investigated the catalytic pyrolysis of polypropylene (PP) and low-density polyethylene (LDPE) using 10 wt.% red mud and 10 wt.% limestone catalysts in a batch reactor. The process was conducted at an operating temperature of 350°C with retention times of 30, 60, and 90 minutes. The effects of adding red mud and limestone catalysts on the yields of liquid, solid, and gas pyrolysis products were analyzed. The pyrolytic oil was further evaluated using droplet evaporation measurements, equipped with a K-type thermocouple and a CCD camera to monitor droplet evolution within an atmospheric chamber. The addition of catalysts enhanced the liquid product yield while reducing the solid yield. The catalytic pyrolysis successfully facilitated the isomerization of plastic polymers, breaking the carbon chains of PP with 10 wt.% red mud. Olefin content increased by up to 7.3% for both 10 wt.% red mud and 10 wt.% limestone. Furthermore, the evaporation rate constant of the catalytic pyrolysis oils improved by up to 8.3%. This study aims to provide new insights into utilizing local waste materials to enhance the quality of pyrolytic plastic products.

Abstract

The consumption of petroleum fuel in Indonesia is increasing, makes the globe climate change a lot. Thus, requiring a renewable energy alternative source such as biodiesel. This study analyzed the single droplet combustion characteristics of soybean oil-based biodiesel produced via transesterification using two heterogeneous catalysts: papaya leaf (PL) and papaya leaf combined with animal bone (PLAB). For comparison, petroleum diesel fuel also tested. Results show that catalyst origin significantly influences combustion behavior. PL exhibited the longest droplet lifetime 7,135 mm/s2 and the highest peak temperature (546 °C), while PLAB showed shorter droplet lifetime 5,001 s/mm2and a lower peak temperature (467 °C), closer to petroleum diesel (4,081 s/mm2 and 254 °C), respectively). In terms of ignition delay, petroleum diesel ignited fastest (3,528 s/mm2), followed by PLAB (4,837 s/mm2) and PL (0,612 s/mm2). The combustion behavior of PLAB is correlated with its higher FAME purity (98%) and methyl linoleate content (43.69%), as reflected by the reduced droplet lifetime. This suggests that the catalyst primarily improves biodiesel quality via enhanced transesterification efficiency, which in turn affects combustion characteristics.
