Abstract

Innovation in sustainable agriculture is key to improving the productivity and quality of agricultural products, especially in areas with low soil fertility challenges. This service activity explored the impact of the application of Biochar and Bioactivator (BnB) technology on the growth medium of banana Kepok Tanjung seedlings in Sijunjung Regency. Biochar, which is produced from the pyrolysis of rice husks, serves to improve water retention and nutrient availability, while bioactivators accelerate the decomposition of organic matter and increase soil microbial activity. Through the method of socialization and structured demonstrations, the initial hypothesis of the activity provides an overview that the use of BnB technology significantly improves the growth parameters of seedlings, including an increase in stem diameter by 15.6% and an increase in the number of leaves by 26.2%. Statistical analysis showed a consistent Z-score and a very significant p-value (<0.001), from this hypothesis it confirms the effectiveness of this technology in improving the quality of the growth media of banana Tanjung Kepok seedlings. These findings not only provide an overview of the potential of BnB technology in banana cultivation but also offer sustainable solutions to increase agricultural productivity in areas facing similar challenges. Recommendations for follow-up service activities include optimizing application doses and evaluating long-term impacts on the sustainability of soil ecosystems.
Pengaruh Aplikasi Fly Ash Terhadap Sifat Kimia Tanah, Kadar Hara Makro, Silika, Logam Berat Dalam Jaringan Tanaman, Pertumbuhan dan Hasil Padi Sawah Lenin, Ismon; Hermansah, Hermansah; Agustian, Agustian; Syarif, Auzar; Dariah, Ai

Abstract

Fly ash berpotensi digunakan sebagai pembenah tanah dan  sumber hara tanaman, karena bersifat basa (pH 8-12), kadar hara silika tinggi, mengandung hara makro dan mikro yang dibutuhkan tanam. Penelitian bertujuan untuk mengetahui pengaruh aplikasi fly ash terhadap  kadar hara makro, silika dan logam berat pada tanah, tanaman, dan gabah serta hasil padi sawah.  Penelitian dilaksanakan dari bulan Juni-Desember 2024. Penelitian disusun dalam Rancangan Acak Kelompok  9 ulangan dan  3 perlakuan (Tanpa fly ash, 5 ton fly ash+1 ton pupuk kandang/ha, dan 5 ton fly ash/ha). Variabel yang diamati yaitu: 1) sifat kimia tanah dan kandungan logam berat sebelum dan sesudah perlakuan, 2) kadar hara makro, silika dan logam berat  dalam jaringan tanaman dan gabah, 3) pertumbuhan tanaman, komponen hasil, dan hasil/ha. Hasil penelitian menunjukkan bahwa tingkat kesuburan tanah tergolong rendah. Pemberian fly ash meningkatkan   C-organik,  P-total,  P-tersedia, Si-tersedia dan dan menurunkan kadar logam berat. Aplikasi fly ash meningkatkan kadar Si tanaman dan menurunkan kadar logam berat dalam jaringan tanaman dan gabah, meningkatkan anakan produktif dan hasil. Hasil tertinggi (8 t GKP/ha) didapatkan pada perlakuan 5 ton fly ash + 1 ton pupuk kandang/ha.

Abstract

Oil palm productivity is closely linked to the nutrient status of its leaves, which serve as a reliable indicator of plant health and fertilizer requirements. Comparing leaf nutrient levels at different ages, such as 6 and 8 years, provides valuable insights into the dynamics of nutrient uptake and the optimization of fertilization strategies for sustainable yield. This study was conducted to assessing the macronutrient adequacy status of oil palm leaves based on diagnostic standards, and knowing the differences in these nutrients at ages 6 and 8 years. Leaf samples were taken from Kampar District, Riau Province by systematic random sampling of 14 oil palm trees to represent 20 ha of each age class. Leaf samples are leaves located on the 17th leaf sheath in the oil palm leaf phyllotaxis system. Analysis of plant nutrient levels using the X-ray fluorescence (XRF) series PAnalitycal Epsilon 3 method except for N-total with Kjeldhal (% dry weight). Results revealed that 6-year-old oil palms had optimal amounts of N, K, Ca, and Mg, along with elevated P and S. Conversely, 8-year-old palms showed deficiencies in N, K, Mg, and S, but optimal level of Ca and high P levels. T-test analysis (P value < 0.05) indicated significant differences in N, K, and S between the two age groups, while P, Ca, and Mg did not differ significantly.
