Background: Frozen shoulder is a joint disorder that causes limited motion of the shoulder joint in all directions of movement, causing both physical and functional problems. This activity aims to see the benefits of manual therapy and pendular codman exercises in increasing the activity of frozen patients at Grandmed Lubuk Pakam Hospital in 2019. Manual therapy methods and codman pendular exercises were given to 24 patients at the Physiotherapy Clinic of Grandmed Lubuk Pakam Hospital. The measuring instrument used to measure the functional activity ability of the shoulder is the index of shoulder pain and disability with the 0% -60% category being improving and 61% -100% being worse. Based on the results obtained during manual therapy and codman pendular exercise, it shows that the ability of the patient's shoulder functional activity has increased. where manual therapy and pendular codman exercise from 16 samples, the ability of shoulder functional activity with a SPADI value of 100% decreased and after manual therapy and pendular codman exercises for 3 times decreased to 12.5% â€‹â€‹decreased and 87.5% improved. Based on these data it can be neglected that there is an effect of offering manual therapy exercises and pendular codman in increasing the patient's shoulder functional activity by 87.5%

Osteoarthritis is a chronic degenerative disorder that primarily affects the articular cartilage of the synovial joint, and ultimately bone and remodeling (spurs) at the joint boundary occur. Synovial thickening and capsule progression and joint effusion also occur. Disorders due to Osteoarthritis cause limited activity and limited ability in activities. Because, damage to the cartilage (cartilage) of the joint, so that the thickness of the subcondral bone increases, sclerosis of the bone plate, the growth of osteophytes in the joints, can stretch the joint capsule, resulting in inflammation, and weakening of the muscles connecting the joints. This study aimed to determine the effect of Manual Traction and Isometric Exercise in patients with Knee Osteoarthritis at Grandmed Lubuk Pakam Hospital. Using quasi experiments with one group pretest posttest with a sample of 19 respondents. Measurement of Functional Activity with Jette Scale, using paired sample t-test analysis. There is a significant influence on functional activities before and after. hypothesis test by paired sample t-test obtained with the results of p-value < Î± (0.001 <0.05). There is the Effect of Manual Traction and Isometric Exercise on Functional Activity Enhancement in Patients with Knee Osteoarthritis at Grandmed Lubuk Pakam Hospital. Researchers suggest that the next researcher add a number of samples and a longer time so that the results obtained are more maximal.

The urgency of funding student creativity programs within the Triple Helix framework to encourage the independence of the defense industry is a step forward in making economic progress, especially the defense industry. The SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis method is used as a research framework to evaluate the internal and external factors that influence the success of the program. This research reveals that funding for student creativity programs has a significant urgency in strengthening the defense industry. Through collaboration between students, industry and the government, this program is able to generate innovation, research and development of new technologies that can increase the competitiveness of the defense industry. The SWOT analysis shows that the strengths of the student creativity program in Triple Helix include access to fresh and innovative student intellectual resources, the ability to combine academic knowledge with the needs of the defense industry, and the encouragement of collaboration and knowledge exchange between all parties involved. Weaknesses identified include a lack of adequate funding, challenges in integrating student activities into a complex industrial environment, and a lack of understanding of the long-term benefits of the program. However, the SWOT analysis also identified significant opportunities, such as the increasing need for innovation and new technologies in the defense industry, government support for collaborative programs involving students, and the potential to develop long-term partnerships between the defense industry and universities. The threats faced include intense global competition, the need for constant updating of defense technology, and the potential for gaps between academic knowledge and industry needs if there is not adequate collaboration. In order to realize the independence of the defense industry, this research recommends adequate funding for student creativity programs, provision of supporting infrastructure, increased collaboration between universities, industry and government, as well as the development of a long-term strategy to ensure the sustainability of this program.

Composite propellants are the primary fuel in rocket propulsion systems, consisting of a binder, fuel, and oxidizer. Ammonium perchlorate (AP) has long been used as an oxidizer in composite propellants due to its high performance and optimal combustion characteristics. However, the use of AP has negative environmental impacts due to hydrogen chloride (HCl) emissions, which contribute to air pollution and the potential for acid rain. Therefore, environmentally friendly alternative oxidizers are needed to support the defense industry. This study employs a qualitative method based on a literature review to analyze alternative oxidizers such as ammonium nitrate (AN), ammonium dinitramide (ADN), hydrazinium nitroformate (HNF), and hexaazaisowurtzitane (HNIW). The findings indicate that ADN is the most promising alternative to AP due to its good oxygen balance, high specific impulse (Isp), and more environmentally friendly combustion products. Meanwhile, HNF and HNIW exhibit high performance but are less stable and more sensitive to shocks. AN is a more economical and readily available oxidizer; however, it has limitations in terms of thermal stability and burn rate. These alternative oxidizers have the potential to replace AP in reducing environmental impact while supporting the self-sufficiency of the defense industry, considering aspects of safety, energy efficiency, and environmental impact. Further research is needed to enhance the stability of ADN and develop more efficient and sustainable production strategies for alternative oxidizers.

Natural fiber-based composite boards have gained increasing attention as a sustainable and eco-friendly alternative to conventional construction materials. While these materials offer notable mechanical performance and material efficiency, one of the primary challenges lies in improving their resistance to fire. This review presents a comprehensive analysis of existing literature on the fire performance of natural fiber composites, focusing on the role of fiber type, resin formulation, flame retardant additives, and production techniques. Based on a synthesis of ten experimental studies, it was found that composites combining kenaf fibers with phenolic resin and ammonium polyphosphate (APP) demonstrated the highest fire resistance—indicated by a Limiting Oxygen Index (LOI) exceeding 30%, longer ignition times, and slower burn rates. Additionally, fabrication methods such as hot pressing and surface coating proved effective in enhancing thermal resistance. Despite their promise, the adoption of these composites in broader industrial applications is hindered by challenges including energy efficiency, additive costs, and long-term stability. This review suggests that future development should integrate innovative material science with sustainable manufacturing strategies to produce fire-safe, cost-effective, and environmentally responsible composite panels.
