Forest and land fires were national and international disasters that caused crucial environmental problems and were a local and global concern. This research was conducted to determine the factors that affected forest and land fires in the media frame for future disaster mitigation in addition to the existing restoration efforts such as rewetting, revegetation, and community economic revitalization to minimize its impact. Data were collected from 2012 to 2021 through the framing method and analyzed using content analysis. The results showed that the factors affecting forest and land fires from September 2019 to June 2021 were associated with human activity and natural events. The dominant human activities were land preparation for agriculture and settlements, illegal logging, and lack of public awareness. Meanwhile, the natural factors were the dry season, lightning strikes, and areas with less intensive management, such as non-residential areas.

This study aimed to determine the chemical compounds in A. decurrens gum and its bioactivity potential. Extraction was carried out in multilevel with the reflux technique using n-hexane, ethanol, and water as solvents. The chemical compounds were identified using Gas Chromatography-Mass Spectrometry (GC-MS). The amount of A. decurrens gum extract yield, total phenolic content (TPC), total flavonoid content (TFC), and total flavonols content (TVC) were then analyzed quantitatively. Furthermore, bioactivity in the form of antioxidant activity was analyzed with the 2,2-diphenyl-1-picrylhydrazil (DPPH) method, while the cytotoxicity level was assessed using the brine shrimp lethality assay (BSLT). The GC-MS analysis showed that the n-hexane-soluble fraction contained alkane, alkene, aldehyde, ester, and aromatics, while the ethanol-soluble fraction contained monosaccharide and fat group compounds. The water-soluble fraction contained only the monosaccharide group. The highest content value was obtained from the ethanol-soluble fraction, namely TPC, TFC, TVC, and antioxidant activity of 19.61±0.47 mgGA/g, 23.89±1.32 mgQE/g, 13.41±0.81 mgCE/g, and IC50: 3.842 g/mL, respectively. The cytotoxicity content obtained from each fraction sequentially was 0.47 ppm, 5.91 ppm, and 6.56 ppm for n-hexane, ethanol, and water, respectively.

Policies on social forestry would be effective when translated into operation by lower forestry bureaucrats. This research aimed to analyze the discretion and interpretation of local forest bureaucrats on Indonesian social forestry policies. This research applied a documentary study, with data collected from policy documents issued by the Provincial Government of DI Yogyakarta and interview materials of 14 source persons from the Local Forest Bureaucrats (LFB) and farmer groups. The results showed that the DI Yogyakarta Provincial Government had produced numerous policy instruments to regulate the mechanism and profit-sharing of social forestry schemes within the Yogyakarta Forest Management Unit (FMU). The discretions proved the bureaucrats prefer forestry partnership cooperation to the licensing schemes. They also preferred utilizing environmental services for nature tourism to timber forest products due to the complexity and complicated harvesting procedures. These preferences were motivated by their views that increasing provincial government revenue and local beneficiaries from the forests were more achievable through partnership schemes and nature tourism. This research indicated a delay in the social forestry implementation through a licensing scheme. However, the creative discretion of the local forest bureaucrats could accelerate the implementation of forestry partnership cooperation schemes.

The calorific value is a parameter of palm biomass to determine its energy value. Extractives of wood is one of the factors that affect the calorific value. This study aimed to prove the positive effect of extractives on increasing calorific value by identifying the effect of adding extractives on low calorific value biomass. The study used three species wood energy, i.e., Calliandra calothyrsus, Gliricidia sepium, and Leucaena leucocephala. The soxhlet extraction was carried out to isolate extractives from sample. The calorific value sample and residue after extraction were analyzed to evaluate the changes of calorific value due to loss of extractives. The effect of extractives on the calorific value was confirmed by adding wood extractives to the palm biomass. The results showed that the extraction process reduced calorific value of residue ranging from 2.63 to 5.88%, and the bark it ranged from 5.52 to 6.70%. The addition of wood extractives to palm biomass increased the calorific value about 5.86-10.33%, while the addition of extractives from bark increase the calorific value by 6.45-9.05%. Based on the results of these studies prove that extractives have a positive effect on increasing the calorific value and can be used as an additive to increase...

The multi-function forests establishment is an appropriate solution for the paradigm transition in forest management from timber management into ecosystem management. Inclusive economic and environmentally friendly business models become a necessity in forest management to ensure the sustainable functions of forests as life support systems. The multi-business in forestry regulated by Ministerial Decree -PerMen-LHK No.8/ 2021- is in line with the spirit of multi-function forests paradigm to increase forest lands productivity, not only timber but also non-timber forest products and environmental services. Although the government has formulated the multi-function forests development concept and its strategic plan several years ago, the forestry sector's contribution in economic valuation, such as national income (PDB—gross domestic product) and non-tax revenue (PNBP—non-tax state revenue) is relatively low. In this disruption era, this forest management transition becomes a necessity. The multi-function forests establishment could become a realistic management model to implement business diversification and innovation and optimize forestry competitiveness at each business level to accommodate social, economic, and environmental aspects of forest management.

Mangrove forests provide various tropical and subtropical ecosystem services to support sustainable development and people's livelihoods. Ecopreuneurship-based management became an alternative approach for mangrove forests ecotourism. Implementing the ecopreneurship concept in mangrove forest areas could include the utilization of mangrove forest products for business while maintaining biodiversity and the environmental sustainability of the ecosystem. This research aimed to formulate the strategy for ecopreneurship-based management of mangrove forests. This research employed direct observation and in-depth interviews. The respondents were purposively selected based on their specific roles within the communities, community leaders, local governments, and non-governmental organizations surrounding the mangrove forest areas. This research applied SWOT (Strengths, Weaknesses, Opportunities, and Threats) method to analyze the ecopreneurship-based mangrove ecotourism management in Makassar City. The SWOT analysis resulted in three strategies to capture the available opportunities. First, developing community business through innovations in local resource utilization. Second, empowering the community groups such as fishermen, farmers, and women to create mangrove-based household scale businesses. Third, providing training on the post-harvesting mangrove forest products and digital/ online marketing for brown sugar.
