Physical fitness is a fundamental requirement for Marine Corps Cadets, both during their education at the Naval Academy and in their future military service. The role of a Platoon Commander requires excellent physical condition, adequate muscular strength, high endurance, and strong mental readiness. This study aims to describe and analyze the optimization of weight training as a physical conditioning method to improve the physical capabilities of Marine Corps Cadets. The research employed a descriptive qualitative approach using questionnaires, interviews, and documentation as data collection techniques. The subjects consisted of Marine Corps Cadets who participated in weight training programs at the Naval Academy, involving 11 questionnaire respondents and key informants from the Physical Training Department. The results indicate that well-planned, structured, and supervised weight training programs significantly enhance muscular strength, physical endurance, agility, coordination, and self-confidence. Furthermore, weight training contributes to improved physical fitness test scores and the development of a more proportional body posture. Therefore, the optimization of weight training can be considered an essential component of physical training programs to prepare Marine Corps Cadets to become professional and mission-ready Platoon Commanders.

Leadership character development is a fundamental foundation in preparing Indonesian Naval Academy Marine Cadets as prospective Platoon Commanders (Platoon Leaders) in operational units. The complexity of the operational environment, the dynamics of the strategic setting, and the demands of military professionalism require a platoon commander to excel not only in technical and tactical competencies, but also to possess strong, integrity-based, and adaptive leadership character. This article aims to comprehensively analyze leadership character development materials for prospective Marine Platoon Commanders at the Indonesian Naval Academy (AAL) using the Character Cultivation approach and the Military Leadership and Character Development theory proposed by Dr. Charles C. Wong. This study employs a qualitative research method with data collected through expert interviews, document analysis, and SWOT analysis. The findings indicate that the most appropriate strategy for leadership character development is the Strength–Opportunities (SO) strategy, which emphasizes leveraging internal strengths of military education to capitalize on external opportunities, particularly global trends in character-based leadership and the utilization of educational technology. This article, structured equivalently to a minimum of 30 A4 pages, is expected to serve as an academic reference and a policy input for strengthening leadership education for Marine Cadets.

Organic waste management at Yogyakarta International Airport (YIA) is still not optimal, even though organic waste production averages 1,264 kg per month. This community service activity aims to develop technological innovations through the utilization of eggshell waste and Black Soldier Fly (BSF) maggots into economically valuable pellet feed products. The activity was carried out from October 8 to 15, 2025, involving three workers from the Temporary Processing Site (TPS) of PT Angkasa Pura Indonesia YIA. The implementation methods included an initial survey, education, demonstration of pellet production, and evaluation of participants' skills and product quality. The production process involved drying, grinding the ingredients, mixing the ingredients, molding, and drying the pellets. The results showed that the workers were able to independently carry out the production process and produce pellets with good physical quality. Cost analysis showed that the cost of production was IDR 47,989/kg, with a potential profit margin of 30% and an estimated return on investment within ±7 months. This innovation has proven effective in reducing waste volume, increasing the added value of organic waste, and supporting the principles of zero waste and circular economy in the airport area. This program has the potential to be further developed as a model for sustainable organic waste management.

One of the problems of cultivating Betta fish (Betta sp.) which can hamper this cultivation effort is the slow weight growth of the fish. The aim of this research is to determine the effect of providing different types of feed on the growth in weight and color of Betta fish (Betta sp.) size 1- 1.5 in the maintenance tank. The research containers used 27 used gallons with a capacity of 15 liters and each research container was filled with fresh water with a volume of 10 liters. The test animals used were Betta fish seeds measuring 1–1.5 cm. This research used an experimental method using an experimental design in the form of a Completely Randomized Design (CRD) with 3 treatments and 9 repetitions to obtain 27 trials. Other parameters that are also studied include water quality including water temperature ranged from 26,1 – 29 ̊C and pH (degree of acidity) ranged from 7 - 8.
