Tree Community Composition and Structure of Cacao (Theobroma cacao L.) Based Agroforestry in West Sumatera, Indonesia

Abstract

The aim of this study is to obtain basic descriptive account of structure and floristic composition of cacao based pada umumnya adalah dengan cara pengikatan ion & Yuwono, 2017). agroforestry in conserving tree species diversity in West Sumatera. An analysis of the composition and structure of three types tembaga pada membran, penyerapan ke dalam sel, of cacao based agroforestry system (AFS) [cacao - rubber (CR), cacao – coconut (CC) and cacao multistrata (CM)] was Data pencemaran logam berat menunjukkan dan dilanjutkan dengan pengikatan ion tembaga bahwa kadar Cu pada ikan dan kerang dari pantai conducted in April to June 2017. Data collection was done by using quadrat method of 20 x 20 meter plots with a total of 6 oleh protein metallothionein (MT) (Ashish, Neeti, sekitar muara yang berasal dari Rungkut, yaitu plots on each types of AFS. Herbarium specimens were collected and identified. Among all types of these AFS, CC was the most diverse floristically (H’ = 1.02) with the highest total of species (10 species), followed by CM (9 species) and CR (7 species). & Himanshu, 2013). Eksplorasi khamir resisten pantai di kelurahan Sukolilo mengandung 2.290,20 CM has the highest tree density of 1108 trees per ha and the highest total of basal area (30.53 m2 tembaga yang dapat mengakumulasi tembaga perlu ). We also did a comparison ppb dan 5.920,20 ppb. Pencemaran di Rungkut of the floristic composition of cacao based AFS with the nearest natural forest from previous study. There was a large decrease dilakukan untuk mendukung program bioremediasi telah melebihi ambang batas yang ditentukan oleh in the number of non-cocoa tree species from natural forest to AFS, from 139 to 6-9 species. The only native tree species found limbah tembaga di Indonesia demi terciptanya World Health Organization (WHO) yaitu 1.200 both in the forest and AFS is Pterospermum javanicum Jungh. It is concluded that three types of cocoa based AFS in West lingkungan yang terbebas dari kontaminasi logam ppb sehingga dapat membahayakan kesehata
