Abstract


ROSMENDA GINTING:Mapping of Nitrogen and C-Orgnic status on Pineapple
(Ananas comosus L. Merr) plantations owned by people at the village of Panribuan Subdistrict of
Dolok Silau Simalungun District superinted by Ir. Razali, MP. And Prof.Ir. Zulkifli Nasution,
M. Sc.,Ph.D. This research purpose to make a mapping of Nitrogen and C-Orgnic status on
Pineapple plantations owned by people at the village of Panribuan Subdistrict of Dolok Silau
Simalungun District The research start to do on October 2012 until January 2013. Method of taking
sample uses the free method grid survey with detail scale and use correlation method to analysis
data, with interpretating in mapping Nitrogen and C-Organic. Parameter that analysis in laboratory
is Nitrogen and C-Orgnic status. The result of research showing that status Nitrogen devided by 1
status such as; medium (35,44 ha), C-Organic devided by 4 status such as ; Low (0,19 ha), Medium
(1,01 ha), high (12,89 ha), and highest (21,35 ha).C/N devided by 3 status such as ; Low (1,95 ha),
Medium (11,70 ha) and high (21,79 ha). From the analysis data using correlation method, known
that the no effect on the production are Nitrogen and C-Organic but that effect are C/N.
Key words: Mapping, Nitrogen, C-Organic and C/N
