Abstract

Tembesu (Fragraea fragans Roxb) is important tree species for furniture due to its decorative structure, but its propagation facing to the problems on seed availability. Determining explant sterilization technique of tembesu (Fagraea fragrans Roxb.) in in vitro condition is needed to produce aseptic explants for shoot induction in micropropagation techniques. Shoot induction of explants depends on plant growth regulator and growth medium compositions. This study was aimed (1)to analyzing the effect of sodium hypochlorite 10% in sterilization process to obtain aseptic explants, (2) to find out plant growth regulator and growth medium composition on shoot induction of tembesu (F. fragrans Roxb.) in in vitro condition. This study was conducted at Tissue Culture Laboratory, Rumpin Seed Source and Nursery Center, The Ministry of Forestry, Bogor on February ? June 2014. Explants were sterilized using sodium hypochlorite (NaOCl 5.25%) at 10% of concentrations in various durations (5, 10, 15, and 20 minutes). Shoot induction was done using MS medium, MS modified medium, and MS added with 15% coconut water that combined with 1.5 ppm of BAP. The result showed that explants soaked in sodium hypochlorite 10% within 20 minutes was recommended for explants steriliziton technique of tembesu. Combination treatment between BAP 1.5 ppm and MS modified medium was the most favorable culture medium for shoot induction of tembesu.Keyword: Benzylaminopurine, Fagraea fragrans, micropropagation, Murashige-Skoog modified, sodium hypochlorite

Abstract

The degradation of heath forest that caused by tin mining activity effected some environmental problems such as erotion, sedimentation and lose biodiversity. Restoration is become a way to recocover the ecosystem functions. Information about soil physical and chemical properties is needed for land restoration. Soil samples were collected by cluster sampling method in heath forest and two ages succession of ex-tin mineland (less than a hundred years and more than a hundred years). Study results showed that the soils generally were low Cation Exchange Capacity (CEC), organic matter, total nitrogen, available P, macro nutrient and clay content in soil texture. However in ex-tin mineland more than a hundred years, there is a trend of increasing of clay content also some soil parameters. Natural succession supported soil development even it take a very long of time. Restoration on these soil conditions should augmented the organic matter to repare the texture and make up the CEC by applying Legume Cover Crop (LCC) and Seed Soil Augmentation (SSA) technique.Keywords : heath forest, restoration, soil properties, SSA, tin mining.

Abstract

Dieback on jabon seedling caused by fungi Botryodiplodia sp. decreased seedlings? quality and nurseries economic benefits. Less studies on the control of dieback pathogen on jabon seedling used biofungicide from plant extract have been reported nowadays. Mahogany is one of the promising medicinal plants in Indonesia and has potential as an biofungicide. This research aimed to estimate the growth of Botryodiplodia sp. isolate on some culture medium and inhibitation by mahogany seed extract. The poisoned food technique was used to test the efficacy of mahogany seed extract on the isolate growth. The result showed that potatoes sucrose and potatoes dextrose medium most suitable for mycelium growth of the Botryodiplodia sp. isolate. The mahogany seed hot water extract inhibited the growth of Botryodiplodia sp. isolate with the highest growth inhibition was 41.85-59.90% at 50% extract. Microscopical examinaton showed the inhibition of mycelium growth was caused by the changes on hyphae morphology and growth direction which were shrinking and curling due to the cell wall degradation.Keywords : Botryodiplodia sp., inhibitation, mahogany seed extract, medium.

Abstract

Reclamation is an effort to recover ex-mined land to its original function. Revegetation that can be conducted during reclamation is by planting acacia and cajuput. One of the reclamation results is carbon being absorbed and saved in biomass form. Therefore the amount of saved carbon can be estimated from potential biomass. Factors that can affect amount of biomass are age of standing tree, history of vegetation development, climate, and composition and structure of stand. The research shows that biomass potency in Block B (16,70 ton/ha) is larger than that of Block A (14,24 ton/ha). Estimation results of saved carbon potency show that it is directly related with biomass potency. Carbon saved in Block A is 4,14 ton/ha and that of Block B is 5,56ton/ha. This research shows that the ability of mixed stand of acacia and cajuput in saving carbon has not been optimum yet.Keywords: acacia, cajuput, reclamataion, carbon storage.
