Abstract
Sustainable farming systems are agricultural system that are environmentally friendly. Biodiesel is one type of alternative fuel for renewable energy that is environmentally friendly with low CO2 and sulfur gas emissions. Rambutan (Nephelium lappaceum L.) may be used as biodiesel fuel substitute for fuel oil because it contains high fatty acids. Rambutan seed fat can be used in high premium specialty fats. It is necessary to breed rambutan plants through in vitro culture to overcome the availability of raw materials and the quality of seed production. The success of increasing crop productivity followed by environmental sustainability is the application of an environmentally friendly sustainable agricultural system. The main aim of this research is to find out the best growing regulatory substances and varieties in the growth of rambutan plants in vitro. It was carried out using a completely Randomized Design with two treatment factors. The first factor was varieties consisting of rapiah, binjai, ace and the second factor was the growth regulator type consists of four levels: 0 ppm, NAA 0.5 ppm, BAP 4 ppm, NAA 0.5 ppm + BAP 4 ppm. The results showed that the combination treatment of NAA 0.5 ppm + BAP 4 ppm was able to produce an average when the fastest shoots appeared (13.33 DAP), the average when the fastest leaves appeared (20.67 DAP), the average number of leaves (4 leaves), the average number of the fastest roots (21 DAP), the average number of roots (3 roots) and the longest average root is 3.67 cm in the binjai variety.
