Abstract

Urban and regional development needs space and land which then replaces the existence of natural space. The loss of natural space does not give negative impacts as long as it does not exceed ecological carrying capacity.Unfortunately, urban and regional development in Indonesia is dominated by economy motivation than ecology consideration. As a result, several natural disasters occurred such as flood, ground water depletion, land slides etc. Our research objective is to analyze land cover change from natural space to human activity space and several factors which cause it at 4 different regions: Malang Municipal, Batam Municipal, Pemalang Regency and Muaro Jambi Regency. Research result could be used as basic information for local government to arrange planning, use and control spatial change in each area. This research was conducted by using two different time data images with interval 10 years to get land cover change on each region and social economy data from National Statistic Bureau. The model was formulated by using forward stepwise multiple regressions and the result showed that each region has different factors which increase land cover change of natural space such as: (1) Malang Municipal was dominantly influenced by urban sprawl phenomenon, (2) Batam Municipal wasdominantly influenced by government policy to develop industry, (3) Pemalang Regency was dominantly influenced by appearance of several new growth poles, and (4) Muaro Jambi Regency was dominantly influenced by land necessity for agriculture activities.

Abstract

Agarwood is an important forest product due to its high economic value. However, the natural population of agarwood species has been decreasing rapidly because of over exploitation, therefore the international trade of the most important agarwood species (i.e. Aquilaria malaccensis) is restricted to just a small quota. This research was conducted in an attempt to provide basic information for the conservation of Aquilaria spp. by identifying the species spatial distribution and habitat characteristics and developing a linkage model between their abundance and habitat characteristics. Data were collected through a field survey at Kutai National Park in August 2006 with Aquilaria spp. as the target species. Data on the species localities were used to determine the species densities and the value of Distance Index of Dispersion. The ordinance levels between the target species and the surrounding other species were identified using a correspondence analysis, while the linkage model between the species abundance and habitat characteristics was established using an ordinal multinomial logit model. The results showed that Aquilaria spp. had a low density (0.01/ha) and were spatially distributed in a clump pattern. The abundance of Aquilaria species had a close association with soil texture, humidity and acidity, land elevation, air temperature and humidity, and light intensity. The abundance decreased with increasing the proportion of sandy clay loam content, soil humidity and acidity, land elevation, and light intensity. In contrast, the abundance increased with increasing sandy loam content, air temperature and air humidity. The existence of A. malaccensis was likely to associate with the existence of Goniothalamus sp., Macaranga sp., Vordia splendidissima, Lygopodium sp., and Stachyphrynium borneensis.

Abstract

Plant growth distribution patterns are influenced by distribution of habitat characteristics, capacity of adaptation, and association with other plant species or animals. Global climate change has serious impact on the changing habitat which eventually threat plants. This study has objectives: (1) to measure plant growth dependence on their microhabitat; (2) to define microhabitat variables that influence growth significantly; and (3) to formulate suitable conservation efforts for certain species.  Gonystylus bancanus is one of major timber species that has been facing high exploitation in Indonesia. This species is usually found on specific “peat swamps” ecosystem. Data were collected through primary surveys in Riau Province.  Data analyses were peformed by clustering the adult base on variable of height and width of basalt area, and describing distribution pattern of the cluster. Then, Discriminant Function Analysis was used to overlay the cluster with the distribution of microhabitat characteristic consisting of altitude, slope, soil humidity, soil pH, peat depth and percentage of canopy cover. The result shows, distribution of microhabitat match with 67.4% of height distribution and 78.3% of width distribution of basalt area.  Altitude and canopy cover percentage have significant correlation with height distribution (α=0.05).  Meanwhile, altitude, canopy cover, and slope have significant correlation with width distribution of basalt area (α=0.1).  However, peat depth variable shows interesting pattern since shallower peat depth are followed by wider of basalt area. High correlation between plant growth and its microhabitat suggests that in-situ conservation is better strategy than ex-situ conservation and this is particularly true for Gonystylus bancanus conservation management

Abstract

Enviromental carrying capacity was measured in three methods,i.e land capability, land carrying capacity and water carrying capacity. Garut Regency which is located at the upstream Cimanuk Watershed has an important role in the sustainability of capacity for downstream area. The aims of this study are: (1) to identify land use in Garut Regency in 2009, (2) to identify land capability in Garut Regency, (3) to assess the suitability of land use with land capability and space pattern in Garut Regency, (4) to identify the status of environmental carrying capacity in Garut Regency, and (5) to set a space pattern based on environmental carrying capacity. Based on the interpretation of Landsat Satellite Imagery in 2009, dryland agriculture has dominated the coverage about 45.4% and forest cover about 23.8%. This study also shows that most area in Garut Regency is belong to Class IV land capability (36.4% of the regency area) without Class I of land capability. Suitabilty evaluation between land cover and land capabilty describe that 48,45% area is suitable, 50.4% area is not suitable and 1.18% area is conditionally suitable depending on limitation factors that affect land capability. Another evaluation between space patern and land capability shown that 59.0% area is suitable, 32.1% area is not suitable, and 8.84% area is conditionally suitable. Both status of land carrying capacity and water carrying capacity are deficit. According to spatial pattern based on land capability and existing forest, space that can be use as the preservation area is about 58.5% of the area, and space that can be use as the cultivation area is about 41.5% of the area of Garut Regency.Keywords : Land capability, land cover/use, spatial pattern, water carrying capacity

Abstract

Treating gaharu (Aquilaria microcarpa) seedlings with inorganic fertilizers is essential to obtain vigorous seeds with high adaptability for establishment on the field. The aims of this research were to find out the effect of fertilization on the survival and growth rate of Aquilaria microcarpa seedlings and to identify appropriate dosage of fertilizer that could increase the growth optimally. Complete Random Design was employed with two treatments i.e. using root fertilizer (Urea, TSP, KCL) with 5 dosage levels and using leaf fertilizer (Gandasil D and Bayfolan) with 7 dosage levels. Data was analyzed by using statistic descriptive and analysis of variance (ANOVA) method. The parameters used were seedling survival rate, height increase and number of leaves. The result showed that the two fertilizers could increase survival rate of the seedling. However, higher dosage of root fertilizer was followed by lower survival rate. The treatment using root fertilizer had a significant effect on the number of leaves, whereas treatment using leaf fertilizer had a significant effect on the increase of the seedling height. Adding leaf fertilizer is considered more useful in terms of survival and growth rate.

Abstract

Cibotium barometz (L.) J.Sm. (Cibotiaceae) is an important export commodity for both traditional and mod-ern medicine. Populations of this species in several countries have decreased rapidly due to the uncontrolled collection of the rhizome parts for medicinal purposes. Since 1976, this species has been included in Appendix II of the Convention on International Trade in Endangered Species (CITES). This means that no export is allowed without a prior permit issued by the CITES committee.  In order to utilize an endangered species sustainably, the global NDF (Non-Detriments Finding) system is applied for determining annual quotas. Therefore, monitoring and updating the inventory of C. barometz in its natural habitat should be carried out annually. A population study of C. barometz carried out in 2011 in Riau Province, Sumatra, is reported here. The aims of the study were: 1) to inventory C. barometz and determine its variation in Riau Province, Suma-tra, 2) to study the distribution and ecology of C. barometz, and 3) to assess the population size of this spe-cies by using random search methodology incorporating belt line transects. Two variants of C. barometz are recognized; they are the golden yellow and golden brown variants. C. barometz is distributed in eight loca-tions of Kampar District of Riau Province, in the secondary forest and rubber agroforest between 80 m and 600 m above sea level (asl). This species grows well in open to partially opened areas of secondary forest and rubber plantation in hills with a range of slope between 30° and 90°, with a relatively high humidity, 60 – 90%, in acid to nearly neutral soil, with a range of soil fertility from very poor to very humus rich soil.  The average population density determined in our study was 20 plants per 100 square meter. The highest popula-tion size was in the secondary forest of Bukit Kuda Beban at 590 – 600 m asl., viz. 9405 plants with a popula-tion density  of 47 plants per 100 square meter.
