Abstract

Land evaluation of a tract of land, for its suitability to be planted with a particular plantation species is an importantstep for species choice in plantation forest. A weight factor matching (WFM) approach of this study, was used to identifysuitable land for jati (Tectona grandis L.f) in PT. Melapi Timber, East Kalimantan. Land suitability is affected by climate,soil and topograph. According to WFM, the results indicated that important variables which limit T. grandis in theresearch area were pH, cation exchange capacity (CEC), potassium (P) and soil depth condition. The study results showthat 4 of 5 land units are marginally suitable (S3) for T. grandis cultivation in PT. Melapi Timber.Key words: Land evaluation, suitability, Tectona grandis L.f., weight factor matching (WFM)

Abstract

Open mining  causes some environmental impacts such as declining levels of soil fertility, lowering soil pH, and increasing toxic acid mine waste such as Al, Fe, Cu, and Zn. Soil quality can be improved by the addition of soil ameliorant and MycoSilvi, an inoculum of arbuscular mycorrhizae enriched by mycorrhizal helper bacteria. The aim of this study is to analyze the growth response of Anthocephalus cadamba seedlings affected by the addition of soil ameliorant and Mycosilvi grown in soil media from silika sand post mining. The experimental design used in this study is completely randomized design with split pot design that consist of two treatment factors (Mycosilvi and soil ameliorant) with five replications. The main plot is Mycosilvi that consists of two levels (without Mycosilvi and with Mycosilvi). The subplot is soil ameliorant that consist of six levels (compost 0 g, lime 0 g; compost 0 g, lime 5.79 g; compost 0 g, lime 10.58 g; compost 35 g, lime 0 g; compost 35 g, lime 5.79 g; compost 35 g, lime 10.58 g). The interaction of Mycosilvi and soil ameliorant significantly increased height, diameter, biomass, and mycorhhizal colonization of A. cadamba. The Mycosilvi and soil ameliorant (35 g of compost and 10.58 g of lime) was the best treatment to increased height, diameter, biomass, and root shoot ratio of A. cadamba.

Abstract

Harapan rainforest situated in South Sumatera is a restoration area of PT REKI company that highly susceptible to land conversion. The problem faced in the effort of restoration is the restorated area that is too large and has not been tested any silvicultural techniques. The condition of land cover is the basic information that could be used as a reference in the preparation of restoration strategy. The study aimed to determine the level of damage, the condition of the ecosystem, appropriate silvicultural techniques, and plant species restoration priorities. The used methods were analysis of vegetation in 4 typologies (secondary forest, old shrub, young shurb, former akasia plantations), and the analysis of Normalized Difference Vegetation Index (NDVI). The results showed that the correlation between density value (y) and NDVI (x) was: y = -136.35+425.46x, R2 (0.89). The order of  area with the level of damage from the lowest to the highest were: the typology of secondary forest, old shurb, young shrub, and former akasia plantation, respectively. The typology of secondary forests had the highest value of diversity, richness, and evenness  (H’>3, Dmg>5, and E>0.6). Relationship between former akasia plantations typology and another tipologies was not germane (euclidean distance> 3.31), and the relationship between seedling and trees in all typologies (with the exception of former akasia plantations) was  very high  (r> 0.9). Silvicultural techniques that could be done include eradicating A. mangium in the former akasia plantation and planting in the all typologies with the exception of secondary forest. The plants that could be used for restoration are Macaranga sp., K.malaccensis,  Nephelium sp., P.gutta, H.mengarawan, S.leprosula.

Abstract

Failure in degraded forest rehabilitation was caused by using chosen species without pay attantion on site characterictics. Species selection by looking at site limiting factor, will increase success in degraded forest rehabilitation. This research aims to study the influence of physical and chemical soil properties on growth of Shorea leprosula Miq, Shorea palembanica Miq, dan Shorea mecisopteryx. Data was analyzed using multiple linear regression analysis with mean annual increment (MAI) of height and diameter as dependent variable and soil properties as independent variable. The results showed that growth increment of S.palembanica was the most species that influnced by soil perperties with R2 adjusted value for MAI-diameter and MAI-height repectively, 0.946 and 0.674 whereas others two Shorea have R2 adjusted value < 0.5. The research also showed that available P content was the limiting factor of the three species. There was a difference of each species in respond to the available P content. MAI-height on S. mecisopteryx and MAI-diameter and MAI-height on S. pelambanica will increase in line with decreasing available P content while S. leprosula required P available increasing in order to increase of MAI-diameter. This indicates that each species have specific response on certain soil properties content.

Abstract

Natural regeneration of Dipterocarpaceae depends on the availability of the mother trees, flowering cycle, and favorable site conditions. Potential seed of Shorea leprosula in Haurbentes Forest Research, Jasinga District, Bogor, should be supported with sufficient regeneration ability. This research aims to identify the condition of regeneration of Shorea leprosula, environmental conditions and soil conditions that support for the sustainability of the S. leprosula regeneration in Haurbentes Forest Research, Jasinga, Bogor district. The results of the vegetation analysis showed that condition of the forest regeneration S. leprosula in KHDTK Haurbentes quite sufficient for seedling which are found quite a lot and dominating on every block of observations. However, seedlings are experiencing obstacles in resuming its growth to the level of sapling and poles. This can be seen by the existence of another species that dominates at the level of the sapling and the least amount of poles found. The existence of competition with other species and lack of space grows to regeneration due to the dominance of mature trees suspected that caused the regeneration S. leprosula on blocks of thisplant disturbed. Environmental conditions and soil conditions sufficiently support growth of S. leprosula. However, the lack of light intensity that goes into the stands is suspected to be one of the barriers to regeneration of S. leprosula.

Abstract

Shorea leprosula Miq is a Dipterocarps forest plantation that has the prospect of being developed because it is a fast-growing species with high economic value. Given its commercial importance, this study was conducted to analyze the effect of slope class and slope direction on growth. Data were collected using the census method on S.leprosula stands with a spacing of 2m x 2m and 4m x 8m. The direction of the slope is determined based on the configuration of the slope according to the cardinal directions, while the slope of the land is determined based on the classification of the slope class of the land. The results showed that the slope class, slope direction, and the interaction between factors had a significant effect on the growth of S.leprosula. The interaction between the slope class and the direction of the slope produces the highest average annual increment of diameter in the flat slope class with the direction of the slope facing north, which is 1.79 m / year while the highest annual increment of the total average height is in the very steep slope class with to the slope facing to the north at 0.82 m / year.
