PENGGUNAAN SABUT KELAPA SEBAGAI PENAHAN AIR UNTUK MENDUKUNG PERTUMBUHAN TANAMAN SUKUN (ARTOCARPUS COMMUNIS FORST) PADA DTA DANAU TOBA
ABSTRACT: The forest area in
the DTA Lake Toba reduced to thousands of hectares, resulting in a lot of open
land, the land's ability to absorb water is reduced and so the land becomes dry
land productivity declined DTA Lake Toba. Breadfruit plants can increase the
productivity of land and can be used as a plant reforestation to prevent
erosion. Coconut Fiber is one of the media that has the physical properties of
water can hold 6 to 8 times the weight of the dry, and can improve soil
structure and texture, increase soil absorption of water, increase the activity
of soil microorganisms and as a source of nutrients for plants. The purpose of
this study was to determine the effect of various sizes of coco to the growth
of breadfruit. Coconut coir is used ranging in size from 100 grams to 1000
grams. This research was conducted in June-October 2015 in the DTA Lake Toba,
District Silahisabungan, Dairi. Parameters measured were high seeds, seedlings
diameter, canopy area, number of leaves and leaf water content. The results
showed that administration of coco significant effect on the growth of high-
fiber treatment kelpa 600 g ( K6 ) with an average value of 5.88 cm compared to
the control treatment ( K0 ) with an average value of 4.13 cm . no real effect
on the parameters of observation diameter , wide canopy , leaf number , and
leaf water content on the growth of seedlings
