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

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

The main problem of reclamation activities in the postmining land was marginal land that could not support the growth of plants, due to pH and the low level of nutrient. So that, the selection of local species which adaptable and the appropriate silviculture treatment was needed. Jabon (A. cadamba) is one of local tree species that had high prospect, because jabon classified into fast growing species, able to adapted various site conditions, and the silviculture treatment was relatively easy. Dolomit and gypsum were materials that contained of Ca (Calcium), which able being applied to increase the soil pH. This objectives research was to determine the effect of dolomit, crude gypsum and manure fertilizer on the growth of Jabon in postmining land at PT. Tunas Inti Abadi. The fertilizers treatment consisted of three treatments. There were 2 kg of manure fertilizer (N), 2 kg of manure fertilizer + 200 g of dolomit (KN), and 2 kg of manure fertilizer + gipsum 200 g (GN). The parameters that be measured were diameter, height, number of leaves, crown diameter and percentage of living. The combination of dolomit and manure fertilizear had significant effect on the 95% confidence interval the diameter of Jabon.Keywords: calcification, fertilizer, jabon, reclamation
