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

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

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

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

Based on FSVA 2015, Muna District is classified as a food insecure area with a priority level of vulnerability 3 which means it tends to be high as well as being ranked 190 according to the distribution of food insecure areas in Indonesia. This study aims to (1) Compile food insecurity index for each village in Muna District, (2) Classify villages based on regional characteristics in Muna District. Data were analyzed using principal component analysis and cluster analysis. The results of the calculation of the food insecurity index showed there were 4 villages (2.6%) included in the food insecurity category (priority 1), 33 villages (21.7%) were classified as quite vulnerable (priority 2), 94 villages (61.8%) were included the category is quite resistant (priority 3), and 21 villages (13.8%) fall into the food security category (priority 4). Villages with food insecure status (priority 1) and moderately vulnerable (priority 2) mostly have low population welfare characteristics, a high ratio of non-working population, a high ratio of residents without clean water access, and a ratio of households with no waste facilities high bowel water. As a whole, Muna District tends to be food security, as seen from the number of villages in priority 3 and 4, which are greater than 50%.
