Pineapple plants are usually propagated vegetatively by utilizing the base of the fruit (ratoone), stem buds (sucker), fruit buds (slip) and crown (crown). Propagation of plants by utilizing parts of the plant is less effective in meeting the needs because the planting material produced is small and requires a long time. An alternative to the propagation of pineapple to increase the amount of planting material is by tissue culture techniques. This study aims to obtain the best types of complex organic compounds and the right concentration for the growth of pineapple shoots in vitro. The research was conducted in June 2017 until October 2017 at the Laboratory of Agronomy at the Faculty of Agriculture, University of Bengkulu. Complete randomized design with 3 replications was used to allocate 9 treatments of complex organic compounds. The basic media used are the composition of Murashige and Skoog (MS). Treatment consists of 1) Coconut water 100 ml / l, 2) Coconut water 150 ml / l, 3) Coconut water 200 ml / l, 4) Banana porridge 100 gl / l, 5) Banana pulp 150 g / l, 6) Banana slurry 200 g / l, 7) Bean sprout extract 100 g / l, 8) Bean sprout extract 150 g / l, 9) Bean sprout extract 200 g / l. The results showed that at 16 weeks after MS media planting the addition of 100 g / l banana pulp was able to produce the highest plant height with an average of 3.45 cm. MS media with the addition of 200 ml coconut water resulted in the highest shoot height of 1.5 cm and followed by MS with the addition of 100 g / l media of banana pulp with an average of 0.9 cm. MS media with the addition of 100 ml / l of coconut water is suitable for the growth of pineapple roots with the average value of the number of roots and the highest length of roots. MS media with the addition of bean sprout extract with various concentrations is not able to stimulate shoot growth and has a growth response that tends to be slow.

The protected areas in the concession of PT Pulp Toba Lestari (TPL) is allocated mainly for maintaining the high-value conservation areas. Since the areas areadjacent to the local community which has long time accessed and utilized non-timber forest products (NTFPs), it is necessary to take forest management efforts to ensure a sustainable protection function while the needs of the community around the forest are fulfilled wisely. One of the critical parts of forest management is to define the distribution of NTFPs clearly to allow effective governance of natural forest area. A stratified systematic sampling survey was applied to find the type of NTFP and its location within the protected areas for each estate. GIS technology was used to map the distribution of NTFPs.26.67% ofincense was most widely distributed by in the Germ-Plasm Protection area of Aek Nauli Estate, and 20.00% was in the Riparian zone area of Habinsaran Estate. At the pole growth stage, 20,00% of incense was often found in the Green Belt area of AekNauli Estate, and 28.00% was in the Buffer Zone area . Rattan is widespread in the all the type of protected areas in Tele Estate. It was mostly found in Germ-Plasm area (100.00%) followed by the Riparian Zone area (95.00%) and Biodiversity area (92.26%). Aek Nauli Estate was the second best place to find rattan in the Green Belt area (82.86%) and the Riparian zone area (76,00%). Sugar palm and bamboo were not distributed well and 17.14% of them were mostlyfound in the Green Belt area of Aek Nauli Estate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
