Mass propagation technology through somatic embryogenesis has become an alternative for producing sugarcane seedlings rapidly.Application of proper plant growth regulator and concentration contribute to support somatic embryogenesis development. This study applied the combination of liquid and solid culture during proliferation stage to promote cell dispersion of embryogenic callus, rapidÂ embryo somatic production, and improve regeneration potency of somatic embryo. Application of 2,4-D and coconut water during proliferation may expected as proper combination for accelerating somatic embryo development and regeneration.Development of somatic embryogenesis in sugarcane var. Bululawang during proliferation were described in this study. Embryogenic callusfrom induction media were transferred to proliferation media containing MS Basal + vitamin supplemented with sucrose different level of 2,4-D (1 mgl-1, 2 mgl-1, 3 mgl-1, 4 mgl-1 ) and coconut water (0% and 5%).Result showed that low concentration of 2,4-D induced optimum somatic embryogenesis development in proliferation and regeneration. Concentration of single 2,4-D 1 mgl-1 without coconut water Â induced rapid development of scutelar and coleoptilarduring proliferation and resulted in better shoot regeneration. In other way, 4 mgl-1 of 2,4-D concentrationÂ affected to inhibit scutelar and coloeptilar formed as the result of failure callus differentiation.

Sumatran Elephants (Elephas maximus sumatranus) is one of the endemic Sumatran fauna that is protected by Indonesia Law. The Remnant Forest of Acacia District Penyabungan in the landscape of Padang Sugihan is one of the elephantâ€™s habitats in South Sumatra. Habitat degradation and fragmentation, poaching and conflicts become the major threats for the elephant population. Genetic study is one of the efforts to establish a conservation policy. It is necessary to test the quantitative and qualitative of DNA, at the extractions stage from fecal samples, in order to get the standard results on DNA concentration which will be analyzed later. The method used is through direct observation as the initial survey to determine the sampling location. Fecal samples were preserved in absolute ethanol at -20Â°C.Â The extraction process was carried out using the Quick-DNATM Fecal/Soil Microbe Miniprep Kit. Samples were tested quantitatively using a Nanodrop Thermo Scientific, with the expectation that the concentration results were considered to be 1.6-1.8 and continued with the qualitative test of DNA through electrophoresis gel agarose and UV Transilluminator. Of the 20 samples, only 12 samples showed positive results (there were DNA bands). The results of this quantitative and qualitative test could be used to determine a viable sample to be used as a product in the genetic analysis stage of Sumatran Elephants in the Remnant Forest of Acacia South Sumatra.
