PENGARUH PERBEDAAN DOSIS LIMBAH CAIR BIOETANOL (Vinasse) TERFERMENTASI TERHADAP PERTUMBUHAN BIBIT TANAMAN KAKAO (Theobroma cacao L.)
Abstract: Bioethanol’s liquid
waste (vinasse) is one of organic matter that pottentialy as organic
fertilizer. The objective of this research was to observe the effect of vinasse
and get the best dose on seedling growth of the cocoa plant. This research used
completely randomized design non factorial consists of 5 treatments, they are
without bioethanol’s liquid waste, 300 ml/polybag, 600 ml/polybag, 900
ml/polybag, 1200 ml/polybag. Each unit of treatment was repeated 4 times to
obtain 20 units of experiment and the experimental unit comprises 4 plants,
which is two of the plants used as plant samples. Parameters observed were
plant height, number of leaves, steam diameter, leaf area, root volume, the
ratio of crown roots and the dry weight. The results showed that significantly
affect the bioethanol’s liquid waste increase in all parameters and the best
treatment can be obtained by providing a dose of bioethanol’s liquid waste 600
ml/polybag.
