This research aimed to obtain information on the abundance and natural regeneration population of Calamus zollingeri Beccari and identify dominant trees in the site. The study used the descriptive method with a survey technique. A transect of 520 m consisting of 13 plots of 20 × 20 m was established. The number of individuals, the lengths, and diameters of the stems for the seedlings, young, semi-mature, and mature cutting rattan were recorded along with the surrounding vegetation. Relative density, the frequency of rattan plants and trees were summed to obtain the important value index (IVI) of each growth rate. The results showed that the natural regeneration population was quite abundant, i.e. 738.46, 296.15, 132.69, and 25.00 stems ha-1 for seedlings, young, semi-mature, and mature rattan, respectively as a response to logging in which a number of the seedlings tended to increase after logging. The trees associated with C. zollingeri were Baccaurea rasemosa, Celtis philippensis, and Fagraea fragrans. The existence of seedling regeneration is a guarantee to the sustainability of C. zollingeri in the future. Therefore, forests with rattan need to be developed to improve the preservation, utilization, and conservation of its genetic resources, as well as enhancing the community awareness

The Nagoya Protocol on Access and Benefit-Sharing (ABS) was adopted in 2010, but Parties have been facing many challenges to implement the Protocol. The objective of this paper is to provide information on the current status of the ABS implementation in Indonesia, and to present some case studies for drawing the lessons learned. Information was collected through desk study and a Focal Group Discussion involving 25 resource persons from various stakeholders. There were many institutions related to ABS, but unfortunately some key functions for ABS were still not assigned to a specific institution(s). For law and regulations, there was no law and regulations specifically created for ABS (except Law no. 11/2013 on the Ratification of the Nagoya Protocol), but many existing laws and regulations can be used to address various issues related to ABS. From three case studies presented, it was clear that there were many constraints and challenges to implement the Protocol. The institutional arrangement as well as law and regulations are very crucial to ensure a fair and equitable sharing of the benefits derived from the use of genetic resources, under Nagoya Protocol.

Developing growth curve for forest and environmental management is a crucial activity in forestry planning. This paper describes a proposed technique for developing a growth curve based on the SPOT 6 satellite imageries. The most critical step in developing a model is on pre-processing the images, particularly during performing the radiometric correction such as reducing the thin cloud. The pre-processing includes geometric correction, radiometric correction with image regression, and index calculation, while the processing technique include training area selection, growth curve development, and selection. The study found that the image regression offered good correction to the haze-distorted digital number. The corrected digital number was successfully implemented to evaluate the most accurate growth-curve for predicting mangrove. Of the four growth curve models, i.e., Standard classical, Richards, Gompertz, and Weibull models, it was found that the Richards is the most accurate model in predicting the mean annual increment and current annual increment. The study concluded that the growth curve model developed using high-resolution satellite image provides comparable accuracy compared to the terrestrial method. The model derived using remote sensing has about 9.16% standard of error, better than those from terrestrial data with 15.45% standard of error.

Kawasan Konservasi Mangrove dan Bekantan (KKMB) is a protected area that is managed by Tarakan City Government for mangrove and proboscis monkey conservation. KKMB has a few stakeholders involved in the area. In order to create collaborative management, there must be conducted a stakeholder analysis and management. The research aimed to give stakeholder management recommendations for KKMB. Research data was collected through interviews and questionnaires. This research was also conducted to compare two methods in stakeholder analysis, Reed et al. method and Driscoll and Starik method. The result shows that Driscoll and Starik method is more objective to be used for measuring the stakeholder priority. PT Pertamina EP had to be the first priority in stakeholder management because it has great power, urgency, and legitimacy towards KKMB. In order to improve the relationship between stakeholders in KKMB there must be applied a practical strategy. This strategy strives for optimizing the area advantages for all stakeholders and also fulfill the stakeholders' needs for the area, which are facility maintenance, area sustainability improvement, and optimization of tourism activity.

The Indonesian Government accommodates the development of mining sector conducted in forest area based on Forestry Law Number 41/1999 by the scheme of Forest Leasehold License. Reclamation is required to remediate the degraded land caused by mining activity to restore forest structure and function. This study aimed to analyze the implementation of mining reclamation in East Kalimantan forest areas based on its institutional performance. This study is a descriptive qualitative study that implemented the institutional framework of Situation-Structure-Behavior-Performance. From the study, we found that there are 143,804.89 ha of forest area borrowed by 90 units of Forest Leasehold License for coal and mineral mining in East Kalimantan with reclamation progress reached 41.35% over the disturbed areas. Based on institutional performance analysis, it is identified that the challenges in mining reclamation in East Kalimantan forest areas related to regulation, low sanction enforcement, lack of budget, human resource and economic incentives, and the absence of low-cost technology for mining reclamation monitoring and evaluation. Therefore, development of proper regulations is urgently required to improve stakeholder behavior while enhancement of human resource, technology, and law enforcement are also urgent to improve institutional performance of mining reclamation.Keywords:

Effects of Indole Acetic Acid (IAA) and Indole Butyric Acid (IBA) to The Growth and Rooting of Ironwood (Eusideroxylon zwageri Teijsm. & Binn.) Air Layering Bambang Irawan; Rike Puspitasari Tamin; Rizky Ayu Hardiyanti

Due to over exploitation, the population of Eusideroxylon zwageri is decreasing drastically. One simple technique to conserve the last remaining genetic resources of E. zwageri is by air layering. The experiment was divided into two. The experiment was conducted from July 2018 to February 2019. The first experiment was conducted using branches that grew from coppices while the second experiment using twigs that grew from normal adult trees. Randomized Block Design was applied with three replicates. The treatments were consisted of nine concentration of auxin namely 0 ppm of auxin; 1, 000 ppm; 1,500 ppm; 2,000 ppm and 2,500 ppm of IAA and 1,000 ppm; 2,000 ppm; 3,000 ppm and 4,000 ppm of IBA. The result of experiment shows that the IBA growth regulator seems to be more effective in regulating growth and rooting of E. zwageri air layering compared to IAA. Results for air layering which was taken from coppices revealed that 1,000 ppm of IBA obtained the best results. Air layering of branches taken from coppice is possible even without any additional growth regulator. While, air layering of twigs which was taken from normal trees revealed that the best treatment is 3,000 ppm of IBA.

Changes in land use influence the social and economic characteristics as well as the environmental problems in a sub-watershed. To support the management of a sub-watershed, land use scenarios (biophysics) must be prepared and community involvement level must be improved. So far, the factors used for monitoring and evaluating sub-watershed performance have not been used thoroughly. This research is aimed at finding out the social and economic vulnerabilities tied to the monitoring and evaluation of sub-watershed performance across the sub-districts. This research uses quantitative methods employed to process primary data (biotic: vegetation and settlement, and abiotic: land, climate, geomorphology, and geology), secondary data (community data sourced from the data of BPS; Central Bureau of Statistics) of East Kalimantan Province; in September 2017), and socio-economic data (direct interviews using questionnaires). The primary data were obtained after processing map interpretation and from observation. The results show that high socio-economic vulnerability occurs in areas of high land use vulnerability. Sub-watershed management will be successful if it is done through a "collaborative management" involving all stakeholders. The scenario simulations of this research can be used as reference materials for regional governments in planning, compiling, and implementing the Regional Spatial Plan policies.

Publisher : Institut Pertanian Bogor (IPB University)

The utilization of private forests in Indonesia that is not managed properly based on the principle of sustainable yield will result in the depletion of private forests in the not too distant future. Therefore the sustainability of private forest is a necessity that cannot be delayed anymore. The general objective of this research is to find out whether the yield regulation method (Brandis Method) can be applied in private forests. The specific objectives of this study are: (a) to analyze the characteristics of pine private forests and their suitability for the Brandis Method practice, and (b) to know the sustainability of pine forest products in Tana Toraja using the Brandis Method and its institutions. The data collected in this study consist of primary and secondary data. The analytical method used was descriptive analysis and yield regulation method was analyzed based on Brandis Method. The result of this study shows that the yield regulation of the private pine forests in Tana Toraja can be done based on the number of trees using the Brandis Method. The regulation of private forest products based on the number of trees can be carried out if there is support from private forest institutions.

Ritual Capital for Rural Livelihood and Sustainable Tourism Development in Indonesia Yerik Afrianto Singgalen; Gatot Sasongko; Pamerdi Giri Wiloso
Jurnal Manajemen Hutan Tropika Vol. 25 No. 2 (2019)
Publisher : Institut Pertanian Bogor (IPB University)

Sustainable livelihood approach has been a strategic approach that can improve the economy of rural communities and create harmonization of socio-cultural, economic, environmental and political development through policies. However, it is holistic and contextual, enabling the existence of different capital characteristics formed based on the community's culture. The Indonesian context shows that customary rituals of the community in Kakara and Limau villages in North Halmahera Regency are forms of capital that mobilize claims and access to capital such as natural, human, physical, financial, and social capital. This article aims to describe the ritual capital in rural livelihood for sustainable tourism development. Key informants involved were leaders of community, traditions, religion and rural government and they were interviewed to obtain in-depth information about the ritual capital. The results indicate that the ritual capital was integrated with the rural tourism development, enhancing the capabilities of the customary community in the Kakara and Limau Village to access other capital. This finding supports the argument explaining that ritual capital is a livelihood asset in the context of tourism development in North Halmahera Regency, Indonesia.
