Abstract

Mangrove soils in Muara Angke Jakarta were suspected to be polluted with heavy metals. This study describes the analysis to the heavy metal content in those polluted soils. The fungus on those soils was isolated and identified. Results show that heavy metal content of soils of Muara Angke was high, i.e., 1.53 ppm for Pb, 4.59 ppm for Cu and 22.55 ppb for Hg. The fungi that were isolated included Penicilium sp., Eupenicillium sp., Talaromyces sp., Aspergillus sp., Trichoderma sp., and sterile fungi, i.e., fungi that did not produce conidia on PDA medium.

Abstract

The study describes a method for predicting urban forest area in Padang City based upon oxygen needs. The result shows that the needs of urban forest in Padang City increase continously, mainly due to the increase of industries. Since the year 2002, the spatial analysis also found that the significant increase of the urban forest need occurred in Lubuk Kilangan disctrict, i.e., approximately 368,88 hectares per year. In the year 2020, the estimate needs of urban forest in all Padang City are 14,894.61 hectares. This need is approximately 53% of the area. Furthermore, the extent of urban forest is still sufficient for supplying oxigen up to the year 2020. However, it is also the spatial analysis shows that urban forest (vegetated area) are not evenly distributed in the centers of economic activities (e.g. settlement, industries, shopping centre, etc).

Abstract

Increasing forest degradation and community poverty are painful. Meanwhile, the behaviors of forest resources and their stakeholders are poorly understood. Systems dynamics is an approach, which is able to capture the complexity, dynamics and uncertainty of the management of forest resources and to develop future scenarios. This approach is not sufficient, however, if it is not placed in the multi-stakeholder context, where each stakeholder plays an important role. This paper discusses the use of systems dynamic as a tool to facilitate multi-stakeholder process and social learning towards sustainable and equitable forest management. A case study was conducted at Darmaga Experimental Forest, Bogor using software ‘The Bridge’. ‘The Bridge’ facilitated the Darmaga Forest stakeholders to articulate their future vision, strategy and its indicators. Then, they were converted into a systems dynamic model where the future scenarios could be drawn and learned.

Abstract

The study departs from the fact that the most difficult activity in constructing tree volume table is measurement of diameter and length of section of standing sample trees. Besides, the number of sample trees to represent the population is also another problem. This study examines the construction of the volume equation through taper function by reducing the quantity of sample trees. Validation was also conducted for testing the accuracy of such volume equation. The study found that the best taper function was the third order polynomial model i.e., d/D=f{(h/H),(h/H)2,(h/H)3. The volume equation, constructed using only three sample trees by such taper function (V=0.3573337D2H), has almost the same good performance to equivalent the best model (V=6.14 10-5D1.8249H1.0342), that was constructed using 30 sample tree.Key words: taper function, tree volume equation, validation, accuracy, precision

Abstract

This study’s emphasis was on Dayak Merap and Punan people’s perception of the importance of forest. A participatory approach using scoring exercises was completed with seven forest-dwelling communities in the tropical landscape of Malinau, East Kalimantan. The findings suggest that unlogged forest was the most important land category for Dayak people. It provides for their livelihoods and well-being both directly and indirectly. ‘Forest’ has the heritage values and contains an abundance of valued and significant plants and animal. For the future, ‘forest’ is predicted to remain important for local people mainly for timber. Forests are exceptional in comparison with other land types in providing a wide range of highly valued goods and services, in most cases to a greater degree than other land types. In addition, the value of forests decreases less with apparent distances. However, logged forest is related as much less important, allowing us to consider improvements in forest management that might better protect local values.
