Ecosystem Restoration Policy in Production Forest and Its Implementation in Indonesia https://journal.ipb.ac.id/index.php/jmht/article/view/29051 <p><em>The issuance of the Ministry of Forestry Regulation </em>(<em>Number SK 159/Menhut-II/2004</em>)<em> on Ecosystem Restoration in Production Forest marked a paradigm shift in production forest management in Indonesia from timber to ecosystem-based. By 2019, the Ministry of Environment and Forestry </em>(<em>MoEF</em>)<em> has issued 16 ecosystem restoration concessions </em>(<em>ERC</em>)<em> in production forest totaling 622,826 ha, or only 21% out of the 3 million ha of MoEF's target. Although this policy was considered a breakthrough and it garnered significant attention, currently, there is no comprehensive assessment on the development of ERC policy and its impacts on achieving MoEF's target. Applied a combination of policy content, process, and implementation analysis, and rational policy analysis, this research examined the gaps in ER policy and implementation and identified policy space to pursue necessary policy improvement. The findings suggested that existing policy remains inadequate to support the implementation of ERC from the licensing process to performance evaluation. This study has identified the need to revise the applicability of regulations to facilitate the objectives of ERC&nbsp; as a management unit, and the objective of ecosystem restoration in the production forest. Revisions include ecological, social, and economic aspects using available policy space that supported by the coalition of actors within the Ecosystem Restoration Working Group.</em></p> Maria Helena Yeni Pareira Hariadi Kartodihardjo Bahruni Copyright (c) 2020 Jurnal Manajemen Hutan Tropika http://creativecommons.org/licenses/by/4.0 2020-12-12 2020-12-12 26 3 201 201 10.7226/jtfm.26.3.201 Potency and Conservation of Aren (Arenga pinnata (Wurmb) Merr.) in Meru Betiri National Park, East Java-Indonesia https://journal.ipb.ac.id/index.php/jmht/article/view/29178 <p><em>Aren </em>(<em>Arenga pinnata </em>(<em>Wurmb) Merr.</em>)<em> is a high ecological and economical value species of Indonesia. Aren grows spreading in Indonesia including at Meru Betiri National Park in the province of East Java, Indonesia. The community in Meru Betiri National Park uses aren fruit which is called kolang-kaling. Even though aren grows naturally in this area, the community has not maximized its utilization. This study aims to identify the actual and ideal conditions for aren conservation also to analyse the gap between them, and to formulate the conservation actions to realize a sustainable aren conservation in Meru Betiri National Park. The data wascollected by using vegetation analysis and in-depth interviews with all of the aren farmers. Aren regeneration in Meru Betiri National Park is categorized stable and seems to be decreased. The use of aren by the community is limited only from the fruit as kolang-kaling. There is a gap between current and ideal conditions for achieving aren sustainability. To achieve the ideal conditions, conservation actions are needed among aren farmers by utilizing agroforestry systems, increasing the value of aren, intensive coaching for aren farmers, and forming a group of aren farmer.</em></p> Ervizal A.

The main objective of this research was to find key indicators or variables for evaluating the level success of reclamation results in the post-mining of oil and gas area. In this study, 44 environmental variables of the physical, biological, soil, water and air indicators were analyzed from 70 field plots of 6 reclamation and 2 natural forest sites. The analysis methods included </em>(<em>1</em>)<em> cluster analysis using the Agglomerative Hierarchical Clustering method with the Ward's method, and </em>(<em>2</em>)<em> quadratic discriminant analysis. The results of the clustering analysis showed that there were some clusters due to variation of biomass, water, soil and air conditions. The three clusters developed based on water and/or air variables provided high cophenetic correlation </em>(<em>0.80</em>)<em> with low within-cluster </em>(<em>14.5%</em>)<em> and high between-cluster variations </em>(<em>85.5%</em>)<em>. Based on the multicollinearity analysis, average vector difference test, variance matrix variance test, unidimensional test of each variable and quadratic discriminant function, this study found that there were 3 key indicators determining variations of the quality of the reclamation plantations within the study sites, namely, biological indicator of biomass volume </em>(<em>Bio_B</em>)<em>; soil indicator of P content in the soil </em>(<em>Tnh_P</em>)<em>, saturation base of soil </em>(<em>Tnh_Kb</em>)<em>, Manganese </em>(<em>Mn</em>)<em> content in the soil </em>(<em>Tnh_Mn</em>)<em>, Sulfur content in the soil </em>(<em>Tnh_S</em>)<em>, percentage of ash in the soil </em>(<em>Tnh_Ab</em>)<em>, percentage of clay in the soil </em>(<em>Tnh_Li</em>)<em>, and water indicator of chloride content in the surface water </em>(<em>Air_Cl</em>)<em>. The examination on four classes of the reclamation quality showed that the classes were successfully classified having excellent cross-validation error matrix with overall accuracy more than 90%.</em></p> Tirta Negara I Nengah Surati Jaya Cecep Kusmana Irdika Mansur Nitya Ade Santi Copyright (c) 2020 Jurnal Manajemen Hutan Tropika http://creativecommons.org/licenses/by/4.0 2020-12-12 2020-12-12 26 3 222 222 10.7226/jtfm.26.3.222 Tree Risk Assessment with Sonic Tomograph Method at Bali Botanical Garden https://journal.ipb.ac.id/index.php/jmht/article/view/30255 <p><em>Safety perception is the most important part of people's choice in determining tourist sites. Standing trees that are prone to falling are very dangerous for both visitors and employees. Standing tree with decay wood inside is often the cause of tree failure. Therefore, there is a need for research examining the risk of collection and non-collection trees in Bali Botanical Garden. Tree risk checks were carried out using the Tree Risk Assessment method from the International Society of Arboriculture (ISA), which has been modified. The result of this research gives valuable information for the manager to determine tree handling to minimize tree risk.</em></p> Siti Fatimah Hanum I Dewa Putu Dharma Muhammad Bima Atmaja Gebby Agnessya Esa Oktavia Copyright (c) 2020 Jurnal Manajemen Hutan Tropika http://creativecommons.org/licenses/by/4.0 2020-12-12 2020-12-12 26 3 233 233 10.7226/jtfm.26.3.233 Another Law in Indonesia: Customary Land Tenure System Coexisting with State Order in Mutis Forest https://journal.ipb.ac.id/index.php/jmht/article/view/31447 <p><em>Local wisdom has been coexisting with the state system in several places in Indonesia. The Mountain Mutis Nature Reserve in East Nusa Tenggara province is the strict nature reserves, but a customary land tenure system, called suf, exists so far in the nature reserve. The objectives of this study are (1) to organize the historical territorialization process, (2) to clarify the customary land tenure system and activities for livelihoods by local people, and (3) to discuss the challenges of its land tenure system to manage forests sustainably as well as policy methods to harmonize legal pluralism in Mutis Area. Field observation and in-depth interviews with key informants were employed for data collection, and the collected data were analyzed by a qualitative descriptive method. The findings showed the traditional reward and punishment systems regarding extracting non-timber forest products, grazing livestock, and preventing forest fires were working well for sustainable forest management. However, increased pressure on forests due to future population growth appears to have an impact on the traditional system. It also showed the government officers and local people started some discussions to recognize the suf in the formal legal order. However, there were institutional problems to introduce current state systems. Therefore, it is required to flexibly operate or revise the state laws according to the actual situation to harmonize society between state and people.</em></p> Imam Budiman Takahiro Fujiwara Noriko Sato Dani Pamungkas Copyright (c) 2020 Jurnal Manajemen Hutan Tropika http://creativecommons.org/licenses/by/4.0 2020-12-12 2020-12-12 26 3 244 244 10.7226/jtfm.26.3.244 Mapping Multi Stakeholder Roles on Fire Management in Conservation Areas of Kuningan Regency https://journal.ipb.ac.id/index.php/jmht/article/view/30218 <p><em>Forest fire </em><em>was</em><em> a persistent concern management in conservation </em><em>areas of </em><em>Mount Ciremai National Park</em> (<em>MCNP</em>)<em> and</em><em> Kuningan Botanic</em><em>al</em><em> Garden</em> (<em>KBG</em>)<em>. </em><em>Many</em> <em>of the forest fire was sparked by anthropogenic ignitions like </em><em>careless fire use for extracting forest honey</em><em>.

This condition which if not addressed immediately will encourage the community around the TNKS to enter and encroach the forest to meet their household needs. This is getting worse along with the finding that the community around TNKS also does not have many alternative sources of income. For this reason, designing strategies for optimizing household economic to lessen population pressures are noteworthy. Focus group discussion </em>(<em>FGD</em>)<em> and analysis hierarchy process </em>(<em>AHP</em>)<em> was applied to design and to determine development strategy for household economic empowerment and twenty-five key informants including fifteen farmer households were interviewed. The AHP results conclude that the production aspect is the most important that needs to be given priority in the development of plantation production. This conclusion is based on its highest relative priorities (weights), i.e., 0.298. Of the three programs identified and using weight result of AHP, community seed assistance is the most important program in the development of plantation production </em>(<em>weight of 0.494</em>)<em>. The seed assistance program is the most important compared to providing soft loans </em>(<em>weight of 0.29</em>)<em> and expanding to production inputs accessibility </em>(<em>weight of 0.216</em>)<em>. Meanwhile, human resource development aspects are the most attractive strategy for food crop production development, especially rice, with a weight of 0.325. Aspects of human resource development are more focused on improving farmer knowledge in cultivation than marketing and post-harvest handling aspects. Optimization of pekarangan resources is directed to the development of the chicken farm </em>(<em>weight = 0.274</em>)<em> focused on improving the production aspect </em>(<em>weight = 0.328</em>)<em>. Among three priority programs, day-old chicken assistance </em>(<em>weight = 0.512</em>)<em> is more needed than access to soft loans </em>(<em>weight = 0.242</em>)<em> and feed programs </em>(<em>weight = 0.246</em>)<em>.</em></p> Ketut Sukiyono Septri Widiono Copyright (c) 2020 Jurnal Manajemen Hutan Tropika http://creativecommons.org/licenses/by/4.0 2020-12-12 2020-12-12 26 3 268 268 10.7226/jtfm.26.3.268 Application of Arbuscular Mycorrhizal Fungi and Soil Ameliorant on the Growth of Leucaena leucocephala in Limestone Post-mining Soil Media https://journal.ipb.ac.id/index.php/jmht/article/view/31352 <p><em>Limestone mining has the potential into environmental damage that involve modify an ecosystem. The attempt that contrived to reduce the disturbances are rehabilitation. This research was conducted to examine the growth response of Leucaena leucocephala inoculated with AMF and soil ameliorant in a limestone post-mining soil. The design used was a split-plot design in a completely randomized design with 3 factors. The first factor was AMF inoculum (Daemonorops draco AMF and MycoSilvi), the second factor was organic fertilizer of compost, and the third factor was inorganic fertilizer. The variables used in this study expressed by height, diameter, biomass, root colonization, and nutrient absorption of the plant. The analysis showed that the combination of MycoSilvi and compost 7.5% gave best result of height, diameter, and biomass, with significantly increased by 962.67%, 899.41% and 1440.67% to control plant. It also gave best result of nutrient uptake N, P, and K, with significantly increased up to 17.64 g plant-1, 2.42 g plant<sup>-1</sup>, and 18.05 g plant<sup>-1</sup>. In general, AMF showed a good percentage of root colonization with an average 36.67-86.67%.

The reserve is surrounded by human habituation which provide opportunity to study the impact of forest lost on biodversity. In addition, data on Nantu mostly focused on big mammals, as there is no previous herpetofauna survey at the area. Sampling of amphibian and reptile was conducted in June 2013 and in May–June 2014 using Visual Encounter Survey method, glue traps and transect sampling in seven different sites at the eastern part of Nantu. We categorized four habitat types based on human disturbances: high disturbed habitat </em>(<em>HDH</em>)<em>, moderate disturbed habitat </em>(<em>MDH</em>)<em>, low disturbed habitat </em>(<em>LDH</em>)<em> and pristine habitat </em>(<em>PH</em>)<em>. A total of 680 individual amphibians </em>(<em>4 families; 17 species</em>)<em> and 119 individual reptiles </em>(<em>9 families; 29 species</em>)<em> were recorded. Species richness and species composition for amphibians and reptiles differs according to the level of human disturbances. Low level disturbances habitat demonstrated the highest diversity of amphibians and reptiles, whereas as expected, high distubed habitat showed the lowest diversity. Anthropogenic pressures in forest will decrease species richness of amphibian and reptiles. Although most amphibian and reptiles will be able to persist in low disturbances habitat, forest-dependent species will be lost when pristine forests are disturbed.</em></p> Mirza Dikari Kusrini Luna Raftika Khairunnisa Aria Nusantara Agus Priyono Kartono Lilik Budi Prasetyo Novi Tri Ayuningrum Fata Habiburrahman Faz Copyright (c) 2020 Jurnal Manajemen Hutan Tropika http://creativecommons.org/licenses/by/4.0 2020-12-12 2020-12-12 26 3 291 291 10.7226/jtfm.26.3.291 Government Ecology and the Indigenous Religion of the Suku Anak Dalam: Intersubjective Relations in Forest Conservation in Jambi, Indonesia https://journal.ipb.ac.id/index.php/jmht/article/view/31475 <p style="text-align: justify;">Integrating customary-religious values of an indigenous tribe "Suku Anak Dalam” (SAD) and state zoning system in Bukit Duabelas National Park (TNBD), Jambi, Indonesia is a configuration of an intersubjective relationship between government ecology and the religion of indigenous SAD in forest conservation that has not been studied by previous researchers. Hence, this article discusses that intersubjective relationship practice in preserving, maintaining, and protecting sustainable forest by assimilating the SAD's customary-religious values and the state zoning system. Moreover, this article also complements the shortcomings of previous researchers who believe that SAD's cosmology is animistic and proves that the TNBD zoning system's implementation as a cause of the SAD conflict. After conducting the interviews and the observations supported by relevant literature sources, this article shows that the SAD believes that the cosmos is not only inhabited by humans, but there are nonhuman beings such as animals and Badewo who are perceived as a human in which they are believed as social actors in forest conservation. SAD and nonhuman beings live together and contribute to each other and have a mutual relationship to life sustainability in the forest or so-called indigenous religion. Besides, the article also found that the TNBD zoning system is not the primary cause of the SAD conflict, rather the dynamics process in integrating state zoning and indigenous custom-religious spaces between the TNBD offices and the SAD.</p> Khairun Najib Copyright (c) 2020 Jurnal Manajemen Hutan Tropika http://creativecommons.org/licenses/by/4.0 2020-12-12 2020-12-12 26 3 303 303 10.7226/10.7226/jtfm.26.3.303 Conservation of Damar Mata Kucing (Shorea javanica): a Review on Institutional Aspect of Trade System https://journal.ipb.ac.id/index.php/jmht/article/view/29977 <p><em>Damar mata kucing (Shorea javanica) is one of the NTFPs that has been widely managed and utilized by local people around the Pesisir Barat Lampung Province. The Majority of damar repong has been cut down, especially during the last 15 years. One of the reasons for the decreasing of community interest in managing repong damar is due to the decreasing damar prices. The purpose of this research is to analyze market system institution performance for damar cultivation in Pesisir Barat, Lampung Province. IAD framework is used to analyze the institutional approaches&nbsp; For further analysis, marketing margin and price analysis are also used to analyze the price differentiation from the producers level to consumers level. Results of the analysis show that damar market in Pesisir Barat Lampung Province is characterized as oligopsony. Natural characteristics of damar and attributes of community found in the damar trading system influence the behavior, patterns of relationships between farmers and middlemen/traders, and market structure in the trading system. Livelihood, limitation on capital, lack of information and networking, knowledge and abilities to tree management and harvested damar, knowledge of another uses of damar resin, and the ability to use technology directly affecting the damar marketing institution.</em></p> Hanifah Nur'aini Ervizal A.
