Lead (Pb), Zinc (Zn), Chromium (Cr), and Nickel (Ni) were used to establish the Mangrove Sediment Quality Index (MSQi), which assesses and monitors the quality of mangrove sediment. This study was conducted at Matang Mangrove Forest Reserve (MFFR) in Perak, Malaysia to examine changes in MSQi features across seasons, mangrove zones, and sediment depths at three separate MMFR locations. Sediment samples were taken using auger in two different seasons (dry and wet seasons). After the silt was removed using aqua regia techniques, heavy metals were examined using an Atomic Absorption Spectrophotometer. According to MSQi criteria in various seasons at three different locations, the highest concentration of heavy metals (HMs) was detected in the dry season in the least disturbed region at three different locations. During dry seasons, only Cr and Ni levels are higher in moderately and highly disturbed areas. Pb and Zn levels in moderately and highly disturbed areas are higher than in least disturbed areas during the rainy season. MSQi parameters in different mangrove zones at three locations showed that most HMs content is highest in the landward zone and it can be concluded that HMs sources are anthropogenic. Furthermore, MSQi measurements at three locations revealed that heavy metals content is highest at 015 cm and lowest at other depths.</em></p> Ahmad Mustapha Muhammad Pazi; Waseem Razzaq Khan; Noraini Rosli, Ainuddin Ahmad Nuruddin; Seca Gandaseca Copyright (c) 2022 Jurnal Manajemen Hutan Tropika http://creativecommons.org/licenses/by/4.0 https://jagb.journal.ipb.ac.id/index.php/jmht/article/view/37639 Mon, 18 Apr 2022 00:00:00 +0700 Allometric Equation for Estimating Energy Production of Eucalyptus urophylla in Dryland Ecosystems at East Nusa Tenggara https://jagb.journal.ipb.ac.id/index.php/jmht/article/view/36938 <p><em>A precise and accurate energy production quantification, particularly at the individual tree level is needed to understand the potential contribution of eucalyptus plantations to renewable energy development. However, measuring energy storage with a destructive method is inefficient because it requires a large amount of resources. The development of allometric equations is a realistic solution to solve this problem as it facilitates the efficient estimation of energy production from trees. Therefore, this study aims to develop an allometric equation for estimating the energy production of Eucalyptus urophylla in dryland ecosystems in East Nusa Tenggara. The destructive sampling was carried out on 25 sample trees which are evenly distributed from small to large dimensions, while the calorific value of each tree component was analyzed using the bomb calorimeter method. Furthermore, the energy production of each tree was counted by multiplying the calorific value with the total biomass accumulation. To develop an allometric equation, the analysis of regression was applied using several independent variables, such as diameter at breast height (D), combined squared diameter of breast and tree height (D2H), as well as D and H separately. The results showed that the energy production of E. urophylla at the study site varied from 252.56 to 7,813.30 MJ tree-1 with more than 90% accumulated in the stem, followed by foliage (4.62%) and branches (4.05%). The higher the tree dimension, the greater the energy production. Moreover, the equation lnŶ = lna + b.lnD + c.lnH was the best allometric model to estimate energy production with an accuracy of 95.2%. Based on the results, the allometric equation provides an accurate estimation of energy production in E. urophylla.</em></p> Ronggo Sadono, Wahyu Wardhana, Fahmi Idris, Pandu Yudha Adi Putra Wirabuana Copyright (c) 2022 Jurnal Manajemen Hutan Tropika http://creativecommons.org/licenses/by/4.0 https://jagb.journal.ipb.ac.id/index.php/jmht/article/view/36938 Mon, 18 Apr 2022 16:37:50 +0700 The Use of Forest Refugia by Ungulate After the 2015'Fire in Tesso Nilo National Park, Riau-Indonesia https://jagb.journal.ipb.ac.id/index.php/jmht/article/view/37270 <p><em>Wildfires in Indonesia 2015 burnt forests in many protected areas, including remaining forests in Tesso Nilo National Park. We investigated the extent to which 2015's wildfires affect the remaining habitat and the spatial distribution of ungulates in the park by using satellite images to identify burnt and unburnt forest patches. Habitat conditions and the presence of ungulates indicated by the number of ungulate signs were compared between burnt and unburnt areas. The fire devastated trees at different rates depending on tree life form stages. We found that younger trees were more vulnerable to fire. The abundance of ungulates did not differ significantly between burnt and unburnt areas, but all vegetation characteristics were significantly different (Mann-Whitney U-test p-value &lt; 0.05). We surmise that food such as new shoots or leaves, particularly at the edge of burnt areas, attracted ungulates out of unburnt areas. The remaining forest is relatively small, and the park is under continued pressure from illegal conversion, so any further loss of remaining forest as refugia will likely harm the ungulate population. We recommend that management should prioritize the preservation of remaining pristine habitat and the reduction of fire suppression, especially during the dry season.</em></p> Wiwid Prayoga, Muhammad Ali Imron Copyright (c) 2022 Jurnal Manajemen Hutan Tropika http://creativecommons.org/licenses/by/4.0 https://jagb.journal.ipb.ac.id/index.php/jmht/article/view/37270 Tue, 19 Apr 2022 14:16:46 +0700 Habitat Preference and Suitability Habitat of Cuscus at PT Wijaya Sentosa, Teluk Wondama Regency https://jagb.journal.ipb.ac.id/index.php/jmht/article/view/36883 <p><em>Previous studies are most focusing on the species identification and habitat used by cuscus, while habitat changes are the most threats on cuscus. Habitat changes caused by the operation of logging concession such as PT Wijaya Sentosa creates an impact to the habitat selection of cuscus, which is highly dependent on forest cover. Efforts to protect cuscus species in production forests need to be carried out to ensure their sustainability habitat. This study aims to determine habitat preference of cuscus and model the suitability habitat of cuscus. The Neu index calculation is used to measure the level of habitat preference, while the habitat sustainability map is modelled by biotic, abiotic, and human disturbance components into MaxEnt application. Vegetation data is analyzed to describe tree density, tree richness, and strata using of cuscus by SexFI application. The study showed that the most preferred habitat by cuscus is LoA 2018 because LoA 2018 had the most species richness so cuscus might be able to choose their vegetation food. The habitat suitability of cuscus in PT Wijaya Sentosa covers 21,116.59 ha and didn't follow the pattern of increasing Et+ logging but was strongly influenced by logged blocks as much as 55.2% contribution.</em></p> Firman Arief, Nyoto Santoso, Dede Aulia Rahman Copyright (c) 2022 Jurnal Manajemen Hutan Tropika http://creativecommons.org/licenses/by/4.0 https://jagb.journal.ipb.ac.id/index.php/jmht/article/view/36883 Tue, 19 Apr 2022 16:03:27 +0700 Towards Inclusive Indonesian Forestry: An Overview of a Spatial Planning and Agrarian Perspective https://jagb.journal.ipb.ac.id/index.php/jmht/article/view/34941 <p><em>Forest area is the largest and most important part of the territory of the Republic of Indonesia but still faces many challenges, including deforestation, forest fires, peat swamp degradation and poverty of local communities due to horizontal and vertical forestry conflicts. This paper focuses on the analysis of forestry development based on spatial planning and agrarian perspective by conveying various facts. A single and centralistic authority over forest areas does not provide an effective basis for sustainable resource governance. There is a dualism of spatial and agrarian planning system namely between forest areas and non-forest areas. It should be integrated by mainstreaming inclusive collaborative management. We recommend promoting forest areas' arrangement under the control of an integrated spatial planning system for the people's greatest possible prosperity, including forestry management principles and objectives. Rationalisation of forest allocation (spatial pattern plan), which the optimum forest allocation must be viewed from the perspective of the overall spatial balance (both forest and non-forest areas, and between protected and cultivated areas) to provide land for food production, social welfare and environmental functions. Forestry implementation needs to consider the principles of economies of scale and prioritise benefits for local communities living bordering forests areas, especially for food cultivation areas. The government should commit to allocating at least 15 million ha inclusively by prioritising landless farmers and smallholder farmers. Increasing community participation in forest area utilisation and functions is pursued through increasing forest access for the community (social forestry and other schemes) without neglecting conservation functions.</em></p> Ernan Rustiadi, Thomas Oni Veriasa Copyright (c) https://jagb.journal.ipb.ac.id/index.php/jmht/article/view/34941 Tue, 19 Apr 2022 16:42:11 +0700 Ecotourism Pillars Enforcement to Geotourism Destination in Slamet and Serayu Mountainous Areas, Central Java Province https://jagb.journal.ipb.ac.id/index.php/jmht/article/view/38193 <p><em>Nature based tourism, including geotourism, can have the status of ecotourism if they are able to enforce the seven pillars namely: 1) the ecological pillar, 2) the economic pillar, 3) the socio-cultural pillar, 4) the satisfaction pillar, 5) experience pillar, 6) memory pillar, and 7) education pillar. This study aims to analyse the perceptions of tourists towards the enforcement of the seven pillars of ecotourism in geotourism destinations. The study was conducted through a survey using a closed-ended questionnaire with a total number of respondents is 400 people. Data analysis was carried out using comparative quantitative and correlation quantitative methods. The results showed &nbsp;that there was &nbsp;still a “gap” between the pillars of sustainable development and the pillars of the basic needs of tourists. The results of the correlation test showed &nbsp;that the elements of the seven pillars of ecotourism had interrelationship each other. It is necessary to modify the form of geotourism implementation by increasing the aspects of guiding/interpreting for tourists and intensifying the involvement of tourists in all tourism activities. The regional approach are also applied to the development of geotourism so that it is more optimal, integrated and efficient in the use of resources.</em></p> Mafut Munajat, Ricky Avenzora, Dudung Darusman, Sambas Basuni Copyright (c) 2022 Jurnal Manajemen Hutan Tropika http://creativecommons.org/licenses/by/4.0 https://jagb.journal.ipb.ac.id/index.php/jmht/article/view/38193 Tue, 19 Apr 2022 16:43:02 +0700 Positive Law of Environment and John Ruggie Principles: Between Legal Text and Norms https://jagb.journal.ipb.ac.id/index.php/jmht/article/view/36895 <p><em>The aim of this research is to examine the application of the Guiding Principles for Business and Human Rights, that is Protection, Respect and Recovery in the implementation of the Law on Environmental Protection and Management </em>(<em>Environment Law</em>)<em>. In 2015 the government issued the Presidential Regulation Number 75 of 2015 regarding to the National Action Plan for Human Rights 2015-2019 </em>(<em>NAP Human Rights</em>)<em>. In 2020 the government is simplifying laws and regulations with the new concept of legal drafting that is the Omnibus Law of which government stated the law of which be familiar as Job Creation Law. One of the simplified clusters is the Environment Law. The findings show that many amended legal norms in the Environment Law are inconsistent with and even contradictory to the NAP Human Rights. Research is carried out normatively by paying attention to legal issues in social media as legal material, as well as reviewing scientific literature related to the topic of issues, laws and regulations, and court decisions. The conclusion from the research is that the Guiding Principles of United Nations for Business and Human Rights bind Judges in enforcing the Environment Law even though these principles are still at the level of the National Action Plan and have not yet entered into the level of legislation.</em></p> Iwan Erar Joesoef Copyright (c) 2022 Jurnal Manajemen Hutan Tropika http://creativecommons.org/licenses/by/4.0 https://jagb.journal.ipb.ac.id/index.php/jmht/article/view/36895 Tue, 19 Apr 2022 16:43:56 +0700
