This research aims to determine the growth of Rhizophora apiculata mangroves based on height, number of leaves and stem diameter in mangrove nurseries in the Segara Ayu Group, Kedonganan, Bali. The research was conducted for six months, from March to August 2025, using quantitative descriptive methods. Observations were made on 40 plants spread across four demonstration plots, with data collected every two weeks. The environmental parameters measured include temperature and salinity. The results showed that the absolute growth in plant height ranged between 27–31 cm, with relative growth of 27.4–33.7%. The average number of leaves reaches 11 to 18 pieces, while the stem diameter ranges from 1.7–2.7 cm. Environmental conditions at the research location are classified as supporting optimal growth, with salinity of 24–28 ppt and temperature of 28–31°C, In general, Rhizophora apiculata plants show good growth during the nursery period, which indicates that the Segara Ayu location has ecological conditions that are suitable for mangrove rehabilitation activities.

Physical education in schools is still dominated by the introduction of popular sports, thus limiting students' sports literacy and opportunities for early childhood sports development and development. This condition results in less than optimal development of students' overall potential. This community service activity aims to encourage increased sports literacy, the formation of active lifestyle habits, and the emergence of the embryo of woodball athlete development at the school level. The method used is a library-based community service with data collection techniques through book reviews, scientific journals, research reports, and various relevant literature related to student development, sports development, and the introduction of woodball. The data obtained were analyzed using content analysis techniques to identify patterns, concepts, and relationships between variables. The results of the community service indicate that the introduction of woodball as an alternative sport has significant potential to increase sports literacy, support character development, develop motor skills, and encourage more inclusive and sustainable sports development in the school environment.

This empowerment program for senior citizens at Banjarnegara Polytechnic focuses on improving agricultural skills, particularly plant propagation techniques. Many senior citizens, despite their extensive farming experience, rely on outdated methods that yield suboptimal results, such as poor seedling quality and low germination rates. The program, held on October 3, 2024, at Banjarnegara Polytechnic, aimed to introduce modern agricultural techniques and enhance the participants' knowledge and skills in plant propagation. A total of 25 participants from the CoE BKL Istiqomah attended, with educational backgrounds ranging from elementary school to bachelor's degrees. The event utilized a combination of lectures, practical exercises, and discussions to provide both theoretical knowledge and hands-on experience. The lecture, conducted in Room C.1.2, introduced the basics of plant propagation, while the practical exercises took place at the nursery field of Banjarnegara Polytechnic. The participants gained valuable insights into modern techniques, which they applied directly at the site, ensuring a better understanding of the processes involved. The post-event questionnaire revealed that many participants still viewed farming as a valuable and promising profession, though concerns about the future of farming and its generational continuity were raised. Many participants expressed concerns about passing on farming traditions to the younger generation, indicating a gap between the older and younger generations in agricultural practices. Overall, the program successfully increased the participants' skills in plant propagation and revitalized their enthusiasm for agriculture. Through this activity, senior citizens have been empowered with modern farming knowledge, bridging the gap between traditional and contemporary agricultural practices. The program also opened opportunities for seniors to engage in the modern agricultural sector, fostering a sense of confidence and motivation to continue contributing to the community’s agricultural development.

Oil palm plants (Elaeis guineensis Jacq.) are one of Indonesia's leading commodities which have quite high productivity as a producer of vegetable oil, as well as being a source of foreign exchange for the country and employment for the community. The aim of the study was to determine the effect of urea, KCl and chicken manure on the growth of oil palm seedlings. The research location was conducted on Jalan Tapak Lebar I Rt.04, Sidorejo Village, Lubuklinggau Barat II District, Lubuklinggau City, South Sumatra, from September to December 2024. Treatment P1 = No treatment, P2 = Urea fertilizer 5 g/plant, P3 = KCl fertilizer 5 g/plant, P4 = Chicken manure 250 g/plant, P5 = Urea fertilizer 5 g + KCl 5 g/plant, P6 = Urea fertilizer 5 g + chicken manure 250 g/plant, and P7 = KCl fertilizer 5 g + chicken manure 250 g/plant. Each sample treatment consisted of 3 seedlings and was repeated 3 times. Using a non-factorial Completely Randomized Design (CRD), Duncans Multiple Range Test (DMRT). The administration of urea fertilizer at a dose of 5 g/plant and chicken manure at a dose of 250 g/plant gave the best effect on all observation variables, namely: increase in height, increase in the number of leaf stalks, stem diameter, number of leaflets, length of leaflets.  

This article explores a sustainable education program in mustard green cultivation implemented through collaboration between local residents and UNIWARA KKN (Community Service Program) students in Kelurahan Karanganyar. The program aims to enhance the knowledge and skills of local residents in sustainable mustard green cultivation techniques, including the use of appropriate growing media, efficient irrigation techniques, and the management of pests and plant diseases without harmful chemicals. The method used in this study is **Community-Based Participatory Research (CBPR)**: working together with local residents and engaging in hands-on field practice to apply proper cultivation techniques. The research shows that this educational program not only successfully improves local residents' knowledge and skills in mustard green cultivation but also strengthens the relationship between the community and academics. Active community participation in this program results in significant positive impacts, including a reduction in the use of synthetic chemicals, increased crop yields, and more environmentally friendly agriculture
