Abstract

The Damang Saiyo farmer group operates in food crop and vegetable farming. Community service activities in the Damang Saiyo farmer group are conducted using training and application of organic fertilizer from mycorrhizal fungi and photosynthetic bacteria to overcome farmers' problems regarding fertilizer scarcity so that fertilizer is available for plants. One of the technologies applied is mycorrhizal fungi and photosynthetic bacteria. (PSB). Mycorrhizal fungi are a type of biological fertilizer with a mutualistic symbiotic relationship with plant roots, which is beneficial for plants so that plant growth is good. At the same time, photosynthetic bacteria (PSB) are autotrophic bacteria that can photosynthesize and have pigments called bacteriophages a or b. can produce red, green, and purple pigments to capture solar energy as fuel for photosynthesis. The objectives of this community service activity are as follows: (1). Providing information on how to apply Organic fertilizers/biological mycorrhizal fungi and photosynthetic bacteria to vegetable plants, (2). Increase farmers' insight into using biofertilizers for mycorrhizal fungi and photosynthetic bacteria to increase farmers' income. This community service activity occurred at Jorong Balai Kenagarian Batu Balang, Harau District, from June to October 2023. The results of the actions show that the community has been able to make organic/biological fertilizer for mycorrhizal fungi and photosynthetic bacteria and has been able to apply it generously to vegetable plants.

Abstract

Sawah yang baru dibuka memiliki sifat fisik yang buruk dan status hara rendah, disamping gangguan Fe2+ terlarut yang tinggi pada zona perakaran apabila tergenang, sehingga dalam kurun waktu 5-10 tahun belum dapat normal dan hasil selalu rendah yaitu 1,0-2,5 t/ha dan menyebabkan kebutuhan pupuk lebih besar. Pupuk Organo-Kompleks (OK) dapat menjawab kondisi tersebut dan tidak memerlukan waktu 5-10 tahun. Karakteristik pupuk OK diuji dalam dosis dan umur simpan terhadap pertumbuhan dan produksi padi metode SRI. Penelitian dilaksanakan bulan Juni 2019 sampai bulan November 2019 di rumah plastik. Pengujian secara faktorial, faktor pertama dosis OK (A1 = 10 t/ha dan A2 = 20 t/ha) dan faktor kedua umur simpan OK, B1= maksimum 1 bulan; B2= 6 bulan dan B3= 12 bulan dengan kombinasi A1B1; A1B2; A1B3; A2B1; A2B2; dan A2B3 (4 ulangan), data pengamatan dianalisis dengan pengolah data Statistic-8 dan dengan uji lanjut BNT 5%. Peningkatan dosis OK 2x lipat (20 t/ha) dapat meningkatkan pertumbuhan (tinggi tanaman dan bobot jerami), komponen hasil (jumlah malai/rumpun, jumlah biji/malai, bobot 1000 biji, dan persentase gabah bernas) dan hasil gabah. Penyimpanan pupuk OK mampu bertahan hingga 6 bulan dan seterusnya berdampak terhadap penurunan potensinya pada tanaman. Peningkatan dosis OK tidak menaikkan hasil pada lama simpan di atas 6 bulan.

Abstract

Pakcoy (Brassica rapa L.) is a short-lived leafy vegetable with high nutrient requirements and is highly responsive to environmental conditions, making it well-suited for cultivation using hydroponic systems. Additionally, the limited availability of agricultural land in urban areas due to land conversion necessitates efficient cultivation methods that do not rely on soil. Hydroponic systems offer more precise control over nutrient management and the growing environment compared to conventional soil-based cultivation, potentially increasing production efficiency on limited land. The success of hydroponic pakcoy production is significantly influenced by the type of growing medium, which supports root development, maintains water availability, and facilitates aeration and nutrient absorption. Therefore, research on various growing media is essential to identify the most effective medium for enhancing pakcoy plant growth and yield. This study aims to: 1) determine the effect of various growing media on the growth and production of pakcoy plants in hydroponic systems (Brassica rapa L.); and 2) identify the best alternative growing medium for optimizing the growth and production of pakcoy in hydroponic cultivation. The research was conducted from May to July 2025 in the greenhouse of the Payakumbuh State Agricultural Polytechnic, Harau District, Lima Puluh Kota Regency, West Sumatra. This study employed a completely randomized design (CRD) with a non-factorial approach. The factor studied was the growing media, consisting of seven treatments: rockwool, bamboo humus, coconut fiber, chopped fern, rockwool + bamboo humus, rockwool + coconut fiber, and rockwool + chopped fern. The parameters observed included plant height, number of leaves, leaf width, leaf length, root length, and fresh plant weight. The results indicated that variations in growing media significantly affected the growth and production of Pakcoy plants in the hydroponic system. The combination of rockwool and coconut fiber as planting media yielded the best results for Pakcoy plant growth and production. Therefore, the optimal alternative planting media for Pakcoy growth and production in the hydroponic system was rockwool combined with coconut fiber.
