Conflict Resolution of Teluk Cenderawasih National Park Management in Teluk Wondama Regency
Get PDFConflicts of interest have occurred in the management of the area and natural resources of Teluk Cenderawasih National Park (TNTC) in Teluk Wondama Regency, West Papua Province. The implications of the park zoning system resulted in pro-and-contra situations that might create conflicts. With this context, the research aimed to formulate-resolution concepts that were considered suitable to resolve the conflicts for managing the park. The research showed that most stakeholders can be mapped out as key players and subject of conflict, just one as crowd and ones as context setter. The research also revelaed that the zoning system has accomodated the needs and aspirations of all stakeholder. Based on the finding it can be said that the existing conflict models were categorized as no conflict among most stakeholders, latent conflict (between BBTNTC with WWF, BBTNTC with Dinpar, DKP with Waprak, and DKP with Yende), and emerging conflict (between DKP with BBTNTC). The research concluded that the conflict of the park management can be resolved through collaborative management approach that can be developed with shared control by other stakeholders. Collaborative management should be implemented as “step by step process”: (1) strengthening the capacity of BBTNTC, (2) consolidation of BBTNTC with NGO (WWF) and local government (DKP and Dinpar), and (3) establishment collaboration with local community and the other stakeholders
Quick Tecniques in Indentifying Open Area by the Use of Multi Spatial and Multidate Imageries
Get PDFThis study describes the use of multitemporal principal component analysis (MPCA) and vegetation index differencing (VIDN) techniques in identifying open area on post-coal mining sites using multi spatial and multidate of Landsat TM and SPOT 4 XS imageries. The study revealed that the synthetic images derived from stable brightness, stable greenness,s and delta brightness of MPCA summarize information on post-coal-mining opened areas provided overall accuracy of 76.47% for the new ex mining area and 32.69% for old ex mining area. The VIDN method provided relatively lower accuracy than those from MPCA i.e. 58.87% for new ex mining and 13.25% for old ex-mining areas. The study also concluded that identifying open area on post-coal-mining sites using imageries was more efficient than using only ground survey, providing cost efficiency of 29%. Thisindicates that the cost required using satellite image is only 29% of the cost required for ground survey. The study concluded that MPCA is better than VIDN for identifying open area on post-coal-mining sites
Purchase of Development Rights (PDR) Mechanism Application on Cost-Benefit Sharing Principles
Get PDFAlthough North Bandung Area was considered as protected area and watershed area uspstream, but it has characteristic as cultivation and downstream area. An effort to improve protection function is needed to prevent changes in land use. One of them through the purchase of development rights (PDR) mechanism. The appropriateness of the PDR application on the benefit of hydrology only effective when it was carried out in zone rural area and the rural fringe. This condition was caused by land prices which exceeded from landexpetation value, therefore the owner of the land experienced impermanence syndrome. The application of Cost-Benefit Sharing Principles would helped Government of the Bandung City in the aspect of the purchace of development right for the agricultural land in KBU that entered Kabupaten Bandung Barat and Kabupaten Bandung. Whereas, for the Cimahi City it helped the purchase of development right for agricultural land in KBU that entered Kabupaten Bandung Barat
Model Pengembangan Kelembagaan Pembentukan Wilayah Kesatuan Pengelolaan Hutan di Provinsi Papua
Get PDFThe implementation of forestry policy in Papua Province has not been significantly optimal as indicated by the high poverty rate around and within the region and the increasing rate of forest degradation. To overcome the problems of the forestry sector, a policy is introduced in the form of Kesatuan Pengelolaan Hutan (KPH) or Forest Management Units. This policy is an enabling condition for the realization of sustainable forest resources and community welfare. The success of KPH is largely determined by the capacity of local stakeholders that includes understanding, coordination and cooperation, and readiness of the organizations that manage KPH. Therefore, this research was conducted to design an institutional model of establishing the region of KPH and formulate organizational structure of KPH. The study was conducted in Jayapura of Papua Province and Regency of Yapen Islands by the use of purposive sampling method for data/information collecting and decision-making tool of Analytical Hierarchy Process (AHP) for data analyzing, which was then analyzed descriptively. The results showed that the performance in establishing the KPH regions in Papua Province was at the medium level of achievement or approximately 29.50% of the criteria and indicators for the formation of KPH regions. This condition was considered low as result of the poor understanding and ineffective cooperative relationships and coordination among stakeholders. Thus, the formulation of the institutional model should be directed to increase the role, capacity, and effectiveness of stakeholder relations. Regarding to the findings, a state owned enterprise is viewed as highly feasible to manage KPH in Papua Province
Pathogenicity of Rhizoctonia solani
Get PDFPathogenicity of Rhizoctonia solani was studied by evaluating the ability of the pathogen to attack several ages of Pinus merkusii and Acacia mangium seedlings. Results showed that R. solani attacked P. merkusii from seed stage up to seven week-old seedlings, while eight week-old ones were free from the pathogen’s attack. On A. mangium, 16 day-old seedlings were uninfected by R. solani, while 12 day-old ones were still attacked by the pathogen. Pathogenesis of R. solani was also studied by evaluating the activities of cellulolytic and pectolytic enzymes produced by the fungi and compared them with the activities of the same enzymes produced by Fusarium oxysporum. Result showed that R. solani’s cellulolytic enzymes activity, reflected by the activity of C1-cellulase, was lower compared with that of F. oxysporum. On the other hand, R. solani was more intensive degrading pectin medium than F. oxysporum, such phenomenon reflected higher activity of pectolytic enzymes activity of R. solani compared with that of F. oxysporum
Pembakaran Terkendali Sebagai Metoda Alternatif dalam Pencegahan Kebakaran Hutan di Hutan Tanaman Acacia mangium
Get PDFPrescribed burning was well done in Acacia mangium plantation without any trees damaged or dead and no natural regeneration found in the forest floor after fire. Fuel load 3 ton/ha and fuel bed depth 8 cm can be used as a standard for it. Flame temperature reached from 149 °C and 170 °C, and flame length 0.74-0.93 m can safe the plantation for any damage. Three months after burning there was an accumulation of fuel load in the forest floor, therefore 3 months interval is a good solution in preventing the forest from fire invasion
Pengkajian Penerapan Teknik Budidaya Rhizophora mucronata dengan Stek Hipokotil
Get PDFResearch on the vegetative propagation of Rhizophora mucronata using hypocotyl cutting sistem was carried out at Faculty of Forestry, Bogor Agricultural University. Histological analysis of adventitous shoot was done at Biotechnology and Tree Breeding Laboratory, SEAMEO-BIOTROP. Three types of hypocotyl cutting (complete hypocotyl, top part of cut-hypocotyl and bottom part of cut-hypocotyl) were induced using 6-BAP hormones at 0 and 500 ppm. Adventitous shoot of bottom part of cut-hypocotyl appeared 140 days after planting. Shoot from complete hypocotyl and top part of cut-hypocotyl grew earlier than adventitous shoot from bottom part of cut-hypocotyl. Hystologycal analysis of adventitous shoot showed the existance of primary meristem, stipule and leaf primordia. The growth of complete hipocotyl was higher than both of top part of cut-hypocotyl and bottom part of cut-hypocotyl. There was no effect of hormone induction on the shoot growth of them
Study on Impact of Agroforestry Model to the Growth of Teak (Tectona grandis L.F) Plants

The research was conducted for 1 year in teak forest stand (1 years old) with site quality index (bonita) was 3.5. Experimental design with 10 observations per block.Blocks in this research were agroforestry pattern 1 (intercropping during the whole cycle of the main crop) and agroforestry pattern 2 (temporary intercropping). There were 2 treatments: (1) litters of corn crops were put on rows of teak crops and no fertilizers were added,(2) fertilizers were added, but litters of corn crops were taken away, and (3) fertilizers were added, and litters of corn crops were put on rows of teak crops. Area size of each observation plat was 0.05 ha. Analysis of variance on the average increament of total height of teak crop and production of dry kernel (corn seeds which had been detached from corn cob) that showed significant results were further analyzed by the use of Duncan Least Significant Difference Test. Conclusions of this research were: (1) agroforestry pattern 1 had greater effect as compared to agroforestry pattern 2 on the growth of total height of teak crop, (2) agroforestry pattern 1 had greater effect as compared to agroforestry pattern 2 on the production increase of dry corn kernels.Keywords: agroforestry, intercropping, analysis of variance, total height, productio
Prospek Pengendalian Terpadu Penyakit Lodoh pada Persemaian Tanaman Kehutanan
Get PDFDamping-off is one of the diseases that decreases the seedling quantity of most forest trees. Up till now, control of damping-off by using fungicides is widely applied. However, excessive usage of fungicides is harmful for human beings, animals, as well as environment. Integrated management is expected to be applied in managing damping-off on forest-tree seedlings. This prospect is shown by several choices of techniques to handle the disease other than chemical handling by using fungicides, as mentioned in this paper. However, efforts to make the prospect to be achieved are still needed. Focused and well-planned research must be done to combine compatible techniques to support integrated management of damping-off on forest-tree seedlings.
