Abstract

Avocado is one of the important commodities as food and as a source of nutrition worldwide. Previous research shows that avocado has antioxidants that benefit for health, such as vitamins A, C, and E, potassium, and unsaturated fat. So, avocados have various health activities such as preventing stroke, reducing cholesterol levels, skin moisturizers, and functional foods for babies. Therefore, a lot of people want to farm avocados by themselves. One of the groups of farmers with experience comes from Desa Iwul, Bogor. The avocado farm is one of their primary incomes. However, the activity is interrupted due to the planning of land construction. Groups of farmers from Desa Iwul, Bogor might face loss of their sources of income. To overcome this problem, groups of community development from Bioprocess Engineering, Faculty of Engineering Universitas Indonesia tried to transfer knowledge about avocado cultivation techniques using grafting methods. The activities were done for 2 months as a form of training for trainers of selected avocado farmers and training from trained avocado farmers to other avocado farmers and society. The results show that the grafting method has successfully been done not only by trained avocado farmers but to untrained avocado farmers and society. By this activity, the success rate of the grafting method has been increased.Avocado is one of the important commodities as food and as a source of nutrition worldwide.

Abstract

Bioactive materials, particularly phosphate-based glasses (PBG), hold great promise in bone repair due to their controllable degradation rates and bioactivity. This study evaluated PBG porous microspheres (P30) loaded with extracellular vesicles (EVs) for bone tissue engineering, focusing on osteogenesis, EV uptake, and cell invasion. P30 concentrations (5P30, 10P30, 50P30, 100P30, 500P30) were tested for their effects on calcification, EV uptake, and cell migration. Results showed that 100P30 exhibited optimal conditions for osteogenesis and EV delivery, with the highest calcification areas at both Day 7 and Day 14 and the most efficient EV internalization. Meanwhile, 500P30 demonstrated the highest cell migration, supporting pre-osteoblastic migration at this concentration. These findings indicate that 100P30 is ideal for mineralization and EV uptake, while 500P30 enhances cell invasion. This study highlights P30's versatility as a biomaterial for bone regeneration, with specific concentrations tailored to different regenerative goals. These results underscore the potential of P30 microspheres loaded with EVs as an effective strategy for promoting bone repair and regeneration.
