Studi Tentang Kandungan Nitrogen, Karbon (C) Organik dan C/N dari Kompos Tumbuhan Kembang Bulan (Tithonia diversifolia)

Abstract

Research about determining Nitrogen, Organic Carbon from Kembang Bulan plant before and after composting, has been done. Determination of Nitrogen has been done with Kjehldahl methode, organic carbon with Walkey Black methode. Based on the research result that Kembang Bulan plant before composting had the value with part of each Nitrogen and Organic carbon are 3,92 % and 43,49 %, whereas after composting 3-12 days with 3 days interval had part of each Nitrogen, Organic Carbon are 4,48 %, 4,48 %, 4,23 %, 4,13 % and 36,29 %, 31,83 %, 22,44 %, 20, 68 %. With the result that high content of nitrogen recomended that Kembang Bulan plant to use nitrogen source for manure process.
