PEMBUATAN ARANG AKTIF DARI SISA TONGKOL JAGUNG DENGAN AKTIVATOR AIR REBUSAN TANAMAN ANTING-ANTING (Acalypha indica) UNTUK MENINGKATKAN KESUBURAN TANAH

Dry corn cobs contain carbon derived from cellulose, hemicellulose and lignin so that it has the potential to be used as activated charcoal to mix soil media to enrich soil organic matter thereby increasing soil aggregation, soil cation exchange capacity, thereby increasing the absorption of N, P, K, by plants and increasing metabolism. growth of micro and macro fauna in the soil. This research was conducted to introduce a simple method for making activated charcoal to the public. This research applies the koniki method in the making of charcoal and soaking to activate the charcoal. Soil samples mixed with charcoal and soil without a mixture of activated charcoal were compared between their chemical and biological properties and the comparison of their functional value to the growth of Pakcoy mustard using a randomized block design analyzed by F test (ANOVA) and LSD further test. The results of research on making activated charcoal from corn cobs are effective because the raw material is cheap and easy to obtain, besides that, the results of charcoal dry corn cobs have a texture that is easily crushed and mixed in the soil. The comparison of the use of mixed activated charcoal and soil without a mixture of activated charcoal has a significant difference, and the application of activated charcoal is considered to have a significant effect on the results of soil chemistry laboratory tests, exploration tests for soil microorganisms and its function as a planting medium in increasing soil fertility
