UJI PENGGUNAAN SLUDGE LIMBAH KELAPA SAWIT TERHADAP PERTUMBUHAN BIBIT KAKAO (Theobroma cacao L.) PADA MEDIUM SUBSOIL DYSTRUDEPTS
Abstract: This research aims
to determine the effect of sludge palm oil waste on the growth of cocoa
seedling (Theobroma cacao L.) on medium subsoil Dystrudepts and get the best
dose. This research was conducted in October 2014 until January 2015 in the experimental
station on the Faculty of Agriculture, University of Riau, Bina Widya Campus Km
12.5 Simpang Baru Village, Tampan District, Pekanbaru. This research was
conducted by using a completely randomized design (CRD) with 6 treatments and 3
replications. The treatments sludge palm oil waste are: S0 = 0 g/polybag, S1 =
50 g/polybag, S2 = 100 g/polybag, S3 = 150 g/polybag, S4 = 200 g/polybag and S5
= 250 g/polybag. Parameters measured were seedling height, stum circle, number
of leaves, leaf area widest, root volume, the shoot root ratio and seedling dry
weight. The results of research that using of sludge palm oil waste dose of 200
g/polybag to 250 g/polybag on medium subsoil Dystrudepts showed growth of cocoa
seedling is best that indicated of increase the seedling height, stum circle,
number of leaves, leaf area widest, root volume, the shoot root ratio and
seedling dry weight.
