Abstract

During this time the handling of waste water in dairy industry (ALIS) in Indonesia is done by dumping into the river. This activity causes damage to rice fields which are located around the river flow. The yield losses due to ALIS is up to 50%. The friendly method is needed for handling ALIS. Since ALIS is known to contain beneficial macro nutrients for plants growing so potents as an organic fertilizer. This study aimed to optimize the ALIS concentrations (0, 20, 40, 60, 80 and 100% v / v) for the growth and yield of onion (Allium cepa L.) var. Buto Ijo. The results showed, treatment ALIS 60% (v / v) increasedheight ofonion leaves until 24.45 cm. Whereas ALIS treatment on various concentrations had no effect on the number of onion shoots. The yields showed, the highest of fresh weight of biomass, number of bulbs, fresh weight and dry weight of bulbs per clump approximatly 13.03 g g; 12,33 bulbs, 7.79 g and 5.38 g was achieved by treatment of ALIS 80% (v/v). Based on the result ofgrowth and crop yields, ALIS 80% (v/v) was selected as the optimum concentration for onion crop. The ALIS was given100 mL and three times during the growing season.

Abstract

The sente variegata plant (Alocasia macrorrhiza variegata) is a species of ornamental taro. The unique leaf color of sente variegata, which is a combination of white and green, attracts ornamental plant lovers for hunting or collecting. There has been no cultivation effort from the ornamental plant suppliers and traders for multiplication purposes until now. Sente variegata is obtained directly from the forest. This activity can cause extinction. Micropropagation efforts using plant tissue culture techniques are needed for commercial and sustainability issues. This study aimed to determine the effect of 6-Benzyl Amino Purine (BAP) and kinetin on the root formation and growth as one step in the shoot multiplication of sente variegata bulb explants. Variations in BAP and kinetin concentrations used separately in this study were 0, 2, 5, and 10 mg. L-1. The results showed that the application of BAP and Kinetin significantly affected the root growth of sente Variegata. Finally, kinetin 10 mg L-1 is the concentration and type of cytokinins recommended for the formation and root growth of sente variegate.
