Abstract

Karbon organik terlarut (DOC) dalam tanah memainkan peran penting dalam distribusi nutrisi dan konsentrasinya dapat dipengaruhi oleh keberadaan partikel mineral tanah. Kandungan karbon tanah awal dapat mengurangi kapasitas tanah untuk menyerap DOC karena adanya tolakan muatan negatif. Penelitian ini mengkaji pengaruh kandungan karbon dan logam tanah awal terhadapa dsorpsi DOC yang  ditambahkan pada tanah hutan tropis melalui percobaan batch. Kandungan logam berat tanah (Al dan Fe), total karbon organik dan kandungan DOC tanah ditentukan. Untuk menentukan apakah dan bagaimana variasi kandungan karbon tanah mempengaruhi adsorpsi DOC, maka dua tanah dengan kandungan logam dan karbon yang berbeda (tanah permukaan dan bawah permukaan) dari dua sistem transformasi (hutan tropis sekunder dataran rendah dan perkebunan sawit masyarakat digunakan. Karbon organik terlarut diekstraksi dari permukaan tanah yang kaya organik dengan air dan dipekatkan ketingkat yang diperlukan dan digunakan dalam percobaan batch. Karbon organik terlarut berkorelasi negatif dengan kandungan logam tanah terutama pada sub permukaan tanah. Dengan kandungan organik karbon tinggi korelasinya tidak signifikan. Ini mungkin menjelaskan adanya tolakan DOC yang membawa perubahan negatif oleh partikel tanah kaya organik.http://dx.doi.org/10.23960/aec.v6.i1.2021.p12-21

Abstract

Land and forest fire management including aspect; prevention, countermeasures, and handling post forest and land fire. All stakeholders have respective roles in each aspect and expected can contribute and collaborate so that efforts to control fire forests and land in the Batang Hari District can be done effectively and efficiently. There are 31 (thirty-one) stakeholders involved in the land and forest fire management in the Batang Hari District, such as the Technical Implementation Unit of the Ministry of Environment and Forestry, Government of Jambi Province, Government district of Batang Hari, Communities, Plantation and Forestry Entrepreneurs, Social Community Institutions, and Universities. Out of 31 (thirty-one) stakeholders, there are 14 (fourteen) stakeholders enter the category Keyplayer, there are 7 (seven) stakeholders have a role as Subject, 3 (three) stakeholders have a role as Context Setter, and 7 (seven) stakeholders play a role as Crowd.
