Abstract

Local food security is a key element in creating sustainable food self-sufficiency at the community level. Pasigaran Village, Tanjungsari District, Sumedang Regency has agricultural potential that can be optimized through organic cultivation of kailan (Brassica oleracea var. alboglabra). This Community Service activity aims to improve farmers' knowledge in implementing organic farming systems to support healthy food diversification and reduce dependence on synthetic chemical inputs. The methods used include socialization, organic cultivation training, technical assistance, and evaluation of program effectiveness. The results of the activities show that the implementation of organic cultivation techniques on kailan can improve soil fertility, reduce the negative impact of using chemical fertilizers and pesticides, and produce healthier products with high economic value. Pre-test and post-test evaluations showed significant improvements in farmers' understanding and skills regarding organic farming. Thus, the program contributes to strengthening local food security, improving farmers' welfare, and developing a more sustainable agricultural system in Pasigaran Village.

Abstract

Tea productivity is strongly influenced by agronomic management practices, particularly fertilization and pruning, which play critical roles in regulating plant growth, physiological performance, and shoot regeneration. This review aims to synthesize current scientific evidence on how integrated fertilization and pruning management can sustainably enhance tea productivity. A narrative review approach was employed by collecting and analyzing peer-reviewed articles published between 2015 and 2025 from reputable databases, including Google Scholar and major international journals. The review highlights that balanced fertilization strategies, combining inorganic, organic, and biofertilizers, significantly improve nutrient availability, photosynthetic efficiency, and shoot yield. Pruning, when properly timed and executed, stimulates vegetative growth, maintains canopy structure, and optimizes the distribution of assimilates. Several studies demonstrated that microbial-based biofertilizers enabled a 25% reduction in inorganic fertilizer inputs without compromising tea shoot yield, while optimum pruning cycles of four to five years-maintained productivity and canopy renewal. In addition, the proportion of pecco shoots was reported to decline from approximately 70% in the first year after pruning to 19% in the fourth year, emphasizing the importance of proper pruning management.  Importantly, the integration of fertilization and pruning practices produces synergistic effects, resulting in enhanced shoot density, improved yield stability, and long-term sustainability of the plantation. This review emphasizes that integrated nutrient and canopy management is essential to address productivity decline and environmental challenges in tea plantations, providing a scientific basis for developing climate-resilient and resource-efficient tea cultivation systems.

Abstract

Tanaman obat merupakan sumber metabolit sekunder yang bernilai penting dalam bidang farmasi, pangan fungsional, kosmetik, dan industri bahan alam. Namun, produksi senyawa tersebut sering tidak stabil karena dipengaruhi oleh faktor genetik, lingkungan, jenis organ, dan kondisi pertumbuhan. Artikel review ini bertujuan mengkaji peran elisitasi stres abiotik in vitro pada kultur jaringan tanaman obat dalam meningkatkan produksi metabolit sekunder melalui tinjauan respons fisiologis, biokimia, dan metabolik. Penyusunan artikel dilakukan melalui penelusuran literatur dari berbagai basis data ilmiah dengan fokus pada kultur jaringan, stres abiotik, elisitasi, dan metabolit sekunder tanaman obat. Hasil kajian menunjukkan bahwa stres abiotik seperti salinitas, stres osmotik, suhu, radiasi ultraviolet, logam berat, dan nanopartikel dapat memicu perubahan status air, turgor, biomassa, klorofil, dan viabilitas kultur. Respons tersebut berkaitan dengan pembentukan spesies oksigen reaktif, aktivasi enzim antioksidan, akumulasi prolin dan osmoprotektan, serta regulasi fitohormon dan jalur biosintesis metabolit sekunder. Dengan demikian, elisitasi stres abiotik in vitro berpotensi menjadi strategi bioteknologi untuk meningkatkan produksi metabolit sekunder tanaman obat secara lebih terkontrol dan aplikatif
