Julia Safriani, Yadi Jufri, Darusman Darusman

Abstract


Abstrak. Biochar atau arang aktif merupakan bentuk karbon stabil yang dihasilkan dari proses pirolisis bahan-bahan organik. Sifat fisik biochar yang memiliki banyak ruang pori, kapasitas air tersedianya tergolong tinggi mampu memperbaiki sifat fisika tanah dan meningkatkan pertumbuhan tanaman. Dalam aplikasi biochar, perbedaan bahan baku dan ukuran partikel memberikan pengaruh yang berbeda pada tanah. Perbedaan bahan baku mengakibatkan perbedaan karakteristik dari biochar yang dihasilkan sehingga kualitas biochar juga bergantung pada jenis bahan dan karakteristik bahan yang digunakan. Tujuan Penelitian ini adalah untuk mengetahui apakah ada pengaruh ukuran partikel biochar terhadap serapan hara. Penelitian ini dilaksanakan dengan metode Rancangan Acak Kelompok (RAK) non faktorial yang terdiri dari perlakuan P0 (kontrol), P1 (2,00-5,00 mm), P2 (1,00-2,00 mm), dan P3 (<0,5 mm). Percobaan dilakukan dengan 4 perlakuan dan 3 kali ulangan, sehingga menghasilkan 12 plot satuan percobaan dengan dosis biochar 15 ton ha-1. Adapun parameter yang diamati adalah serapan hara N, P, dan K. Hasil penelitian bahwa perlakuan ukuran partikel biochar berpengaruh nyata terhadap serapan hara N dan K tanaman jagung. Ukuran yang memberikan pengaruh terbaik adalah (2,00-5,00 mm).

Corn Nutrient uptake affected by various biochar particle sizes

Abstract. Biochar or activated charcoal is a form of stable carbon produced from the pyrolysis of organic materials. The physical properties of biochar, which has a lot of pore space, have a relatively high water capacity able to improve soil physical properties and increase plant growth. In biochar applications, differences in raw materials and particle size have different effects on the soil. The difference in raw materials resulting in differences in the characteristics of the biochar produced so that the quality of the biochar also depends on the type of material and the characteristics of the materials used. The purpose of this study is to find out whether there is an effect of biochar particle size on nutrient uptake. This research was conducted with the design method Non-factorial randomized group (RBD) consisting of treatment P0 (control), P1 (2,00-5,00 mm), P2 (1,00-2,00 mm), P3(<0,5 mm). The experiment was carried out with 4 treatments and 3 replications, resulting in 12 experimental unit plots with a dose of 15 tonnes of biochar ha-1. The parameters observed were nutrient uptake N, P, and K. The results showed that the treatment of biochar particle size had a significant effect on N and nutrient K maize plants. The size gave the best effect was (2.00-5.00 mm).
