Abstract

Plants in Karst Area have different characteristics and distinctive when compared with plants of other forest ecosystem. The purpose of research is to assessing the composition and stand structure and root system of plants in karst areas in Bantimurung-Bulusaraung National Park, Resort Pattunuang-Karaenta. This observation plots determined by purposive sampling based on the representation of the stand. Three sample plots lines with the size of 20 x 100 m each were constructed in the research site. The research was spread out on four habitats that are on hill base, slopes, summit with considerable soil cover, and summit with very little soil cover. The number of species on the research area is amounted 108 species of seedlings and understorey plants, 108 species saplings, 63 species poles and 78 species trees. Horizontal structure inverted J-shaped and vertical structure of the stand consist of four strata (B, C, D, and E strata). Overall, the spatial distribution patterns have a clumped distribution pattern. Uniform distribution pattern is only found in Palaquium obovatum species of pole on slopes and Dracontomelon dao species of tree on base. Pterospermum celebicum has the highest value of shoot-root ratio on the hill base, index root binding highest value with category of moderate (1.5-3.5) on hill base and index root anchoring highest value with the high category (>1.0) on summits with considerable soil cover.Key words: stand composition, root system, stand structure

Abstract

Mangrove rehabilitation activities that are being undertaken in Muara village include seedling and planting activities for various species of mangroves, especially Rhizophora stylosa Griff. (bakau kurap). The villagers have problem to see the differences of ripe and mature fruit according to the activities. They often pick the ripe fruits that still have pieces of fruit although ripe fruits need preface treatment that take long time to be a seed. This study was conducted to obtain information about the development of bakau kurap growth in order to obtain a better cultivation technique based on propagules type at nursery, and the growth in the field based on planting treatments. Those are seedling in polybag, seedling non polybag, and direct seed from propagules. The result showed that during 4 months observation, direct seed from propagules treatment gave effect the highest of height growth about 3.19 cm/month. It suggested that rehabilitation activities should used direct seed from propagules at shallow area.Keywords: mangrove rehabilitation, Muara village, propagules, Rhizophora stylosa Griff.

Abstract

One of the primary sectors that contribute on national greenhouse gas emissions are land use changes. Land use change contributes approximately 50% of national emissions. In the context of climate change, land use change can contribute as the source and sink of carbon. Bogor Regency is one of the districts close to the capital city of Indonesia and industrial areas so that the intensity of land use changes are very dynamic. The aim of this study was to determine the dynamics of land use change and CO2-eq emissions from year 2000 to 2014 in Bogor Regency. Approach to estimate carbon stock change in this study was conducted with stock difference method, the method of calculation of carbon which assesses the carbon deposits at two time points. Most of land use change occurred in mixed garden, wetland, open land, and shrubs that converted into settlement that amounted to 33 283 ha or approximately 11.12% of the Bogor Regency, while the rate of total annual emissions of the greatest historical, namely in the period 2005-2009 amounted to 681 006.94 tones of CO2-eq / year. Increase of emissions occurred in the conversion into other land uses that have a lower carbon stock.Key words: land use change, greenhouse gas emissions, carbon stock

Abstract

This research was conducted in the undisturbed land, underground mining area and illegal mine (PETI) land of Mount Pongkor. This research is aimed to analyze the difference of structure and composition of vegetation, and to predict carbon reserves above soil surface in undisturbed land, underground and PETI, so then adaptive type of vegetation can be identified. This study was conducted by using simple random sampling method with 40 plots. Estimation of carbon stocks using non- destructive method according ISO 7742 2011. The results show that structure and composition between underground is same as undisturbed land with complete stratification which consists of bushes, seedling, pole, trees, liana and epifit, while PETI land has no complete stratification. In PETI land, it’s only found one type of vegetation on pole level that is Vernonea arborea while trees is not found. The species Syzygium lineatum, Lithocarpus sp, Maesopsis eminii, Altingia excelsa, and Ziziphus mauritiana are the species with highest Important Value Index (IVI) in undisturbed land. The Species M eminii, Lithocarpus sp, Altingia excelsa, Vernonea arborea, and Castanopsis argentea are the highest in underground area, so that they are the most dominant species in that location. Species Diversity Index (H’) in undisturbed land is between 1.28-2.62 (medium), while in underground are is between 1.93-2.88 (medium), and in PETI land is between 0-2.45 (very low to medium). Index of Species Richness (R) in undisturbed land and underground on every level of vegetatation is between 1.74-5.9, while in PETI land is lower than 3.5 (very low). Similarity Index (E) in research sites on every level of vegetation is between 0.58-0.98 (relatively uniform), except in PETI land for pole level and trees, the value of E is zero. The potency of carbon stock in undisturbed land was about 288.94 tons C/ha and 192.74 ton C/ha for underground area, whereas was about 0.06 tons C/ha was found in PETI location.Key words: llegal mining, underground mining, suspected carbon stocks, vegetation

Abstract

Research measurements of carbon stocks Avicennia marina has been done by Dharmawan and Siregar (2008) with a DBH 5 cm. Calculation of carbon stocks Avicennia marina with DBH less than 5 cm hadn’t been done. Currently, approaches to measuring biomass and carbon mass mangrove species is being developed through allometric equation. Allometric equation to estimate carbon stocks are still limited, especially for mangrove with DBH less than 5 cm. Therefore, this research carried out calculations to obtain allometric equations for estimating biomass and carbon mass Avicennia marina with DBH less than 5 cm. The results of research can complement allometric equations that have been published previously. Allometric equations constructed using two equations, namely linear and logarithmic with two variables such as total height (x1) and diameter at breast height / DBH (x2). Allometric equation to estimated total biomass, root, stem, branch and leaves are Log YTotal = -7.92 + 2.02 Log (Tt), Log YRoot = -8.37 + 1.94 Log (Tt), Log YStem = -8.83 + 1.99 Log (Tt) + 0.419 Log (DBH), Log YBranch = -8.63 + 2.01 Log (Tt), dan Log YLeaves = -7.73 + 1.63 Log (Tt). Allometric equation to estimated total carbon root, stem, branch and leaves are Log YTotal = -8.82 + 2.21 Log (Tt), Log YRoot = -9.11 + 2.04 Log (Tt), Log YStem = -8.89 +2.06 Log (Tt) + 0.467 Log (DBH), Log YBranch = -9.41 + 2.13 Log (Tt), dan Log YLeaves = -8.46 + 1.64 Log (Tt).Key words: Seedling, stake, total height, diameter at breast height

Abstract

The resiliency of the ex-burnt forest area will following the forest succession stages and resulted to secondary forest. This study was conducted to identified: (1) type and cause of forest fire on September 2012 at Hutan Pendidikan Gunung Walat (HPGW), (2) differences of the vegetation composition of stands, (3) undergrowth succession, as well as (4) differences of soil chemical properties in the ex-burnt and unburnt stands. Fire in HPGW was mainly due to the careless use of fire by local communities when they used fire to burn thatch on their land. Highest index of similarity is found on tree stage at all plots, while the most significant differences found on undergrowth stage. This may related to the vulnerability of the undergrowth to evey changes that occur, one of which is the change on soil chemical properties. Generally, the soil chemical properties at 11th month after fire is better than 6th month after fire.Key word: composition of vegetation, forest fire, soil chemical properties, succession, undergrowth

Abstract

Until now, the supply of the seed sources still rely on seeds or germs. Meanwhie, the certain wood species, the production of seeds are insufficient and the handling is quite difficult. Consequently, when seedling, their germination capacities and growth percentages are very low. Providing seed source through shoot cuttings which if it is planted in advantegous condition for regeneration, it will grow and develop into fast growing species as well as good quality species. Supplying of plant growth regulator is expectedly able to affect the plant growth when given according to the plant needs. This research aimed to determine the concetration level of growth reglator IBA (Indole Butyric Acid) for the growth of shoot cuttings of agarwood Gyrinops verstegii. The method used in this research is experiment with completely-randomized design (CRD). Results showed that the concentration level of IBA affected the growth of callus, roots and shoots. IBA treatment at the concentration of 300 ppm showed the best response to the cutting life, growed earlier, the number and the length of shoot are greater. However, in the root zone, the treatment without IBA hormone provided better response which is showed by the number and the length of root.Key words: Gyrinops verstegii, Indole Butyric Acid, growth response
