Sterculia quadrifida R.Br. Bark decoction is used to treat hepatitis and consumed as a tonic by Timorese in the East Nusa Tenggara Province, Indonesia. Raw herbal materials are susceptible to fungi contamination, have limitations in transportation, and have low economic value. Processing the bark into powder packed in tea bags is expected to overcome these obstacles. Stevia, ginger, and mint leaves are herbs often added to herbal drink formulas. This study aimed to evaluate the antioxidant capacity, total flavonoid content (TFC), total phenol content (TPC), physicochemical properties, and sensory properties of six formulas, namely: (F1) pure S. quadrifida bark; (F2) bark of S. quadrifida and leaves of stevia; (F3) stem bark of S. quadrifida and ginger; (F4) bark of S. quadrifida, stevia, and ginger; (F5) bark of S. quadrifida and mint leaves; (F6) bark of S. quadrifida, stevia, and mint. Total phenolic content was measured using the Folin-Ciocalteu method, and total flavonoids were determined using the AICI3 method. Antioxidant activity was measured using the 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) method. The TPC of S. quadrifida tea ranged from 14.09±0.7 to 68.20±0.95% Gallic Acid Equivalent (GAE), and the TFC ranged from 0.03±0.005 to 0.09±0.004% QE. The Ascorbic acid Equivalent Antioxidant Capacity (AEAC) of F1, F2, F5, and F6 were insignificantly different. F1 contained the highest levels of antioxidants (1,044.3±28.48 ppm Ascorbic Acid Equivalent (AAE)). Formulas with the addition of stevia, mint, and ginger showed weaker antioxidant activity than pure S. quadrifida. F1 and F2 have the potential to be developed as commercial herbal teas

Togenra cave in Madello Village, Barru Regency (South Sulawesi) is located in the Tonasa Karst Formation, known as one of the largest formations in Asia and is also popular for its unique features and functions. Currently, the local government has not yet established a regulation on the management of the cave, and locals are free to access the cave for calcium and guano mining which can threaten the ecosystem of the cave. Therefore, it is necessary to develop non-consumptive use of the cave, through ecotourism that can provide long-term benefits to the local communities. This study aimed to examine the community’s perceptions toward the cave, bats and conservation; formulate strategies by assessing the potency of the cave and bat species as an ecotourism spot based on the local’s perceptions; and provide recommendations for the local government in supporting both ecotourism and conservation in the area. The study was conducted from August 2020 to February 2021. A set of questionnaires were to 31 respondents living within a radius of 1 km from Togenra cave. Formulation of strategies were done by using combined analyses of Strength, Weakness, Opportunity, Threats and Analysis of Hierarchy Process. Our analyses indicate a growth strategy trend. Several strategies drawn emphasize on improving local’s knowledge and perceptions, active involvement of locals, establishment of local management initiatives and regulations, capacity enhancement, and implementation of a stakeholders’ forum. These findings can become a baseline in planning and developing both bat-cave tourism as well as conservation efforts in the area.

Doubtlessly, wood identification is critically important for a number of sectors, including government organizations, the wooden-based industry, museums, law enforcement, and scientists working in the fields of botany, ecology, forestry, and wood technology. Unfortunately, most wood species listed as “the least-known species” lack essential knowledge or even their anatomical feature and basic properties to promote their usage. This research aimed to investigate the anatomical characteristics and fiber quality of the least-known timber species of Apocynaceae family, which are authentic wood collection from Xylarium Bogoriense, namely , Ervatamia. sphaerocarpa, E. aurantiaca, Kopsia flavida, Lepiniopsis ternatensis, Plumeria acuminata, P. rubra, and Voacanga foetida. Wood samples have indistinct growth ring boundaries, diffuse-porous vessels in diagonal and/or radial pattern, vessels in radial multiples of 4 or more cells, simple perforation plate, alternate intervessel pits; distinct borders of vessel-ray pits, similar with those of intervessel pits in size and shape throughout the ray cell, and septate fibers with simple pits to minutely bordered pits which are common in radial and tangential walls. Based on the fiber length and the derived values of fiber dimension, some species are classified into Quality Class II and III, and the rest of them are classified into Quality Class II or III for pulp and paper manufacturing. Based on general characteristics, commonly Apocynaceae can be used as handicrafts raw material. Based on the fiber quality, some species which are classified into Quality Class II, are predicted to have potential as pulp and paper material with medium quality.

Cratoxylum formosum (Jack) Benth. & Hook.f. ex Dyer is one of the plant species that have the potential to be developed into an antibacterial and antioxidant essential oil product. This study was conducted to determine the value of organoleptic tests and the consumers' willingness to pay (WTP) for the three variants of Cratoxylum formosum essential oil products. For the parameters of colour, hedonic test values and score tests showed good results; panellists did not mind the pure and mixed Cratoxylum formosum essential oil colours. However, for fragrance parameters, the hedonic test showed a dislike score. Most panellists disliked the strong "scent of leaves" of pure C. formosum oil. The score test showed satisfactory values, the panellists accept the fragrance of Cratoxylum formosum essential oil, but it is necessary to add a more preferred scent mixture to reduce the strong original fragrance of the oil. The cost of production of Cratoxylum essential oil is Rp.7,259.23 (USD 0.48)/mL or Rp.72,592.30 (USD 4.84) for every 10 mL. Based on the cost ofproduction, the appropriate selling value for every 10 mL of Cratoxylum essential oil is a minimum of USD 4.84.

Seeds always exhibit some degree of dormancy, resulting in a delay and irregularity of germination, and the seeds of Milicia excelsa often have seed germination difficulty. The main objective of this study was to demonstrate the seed germination variations of M. excelsa at room temperature (20-25°C) and incubator (25.6o C). In this study, 400 seeds of M. excelsa were tested using three pre-sowing treatments and control. Each treatment was defined as four replications in which 25 seeds per replication were initially sown in a 90 mm diameter petri dish with disc paper in a completely randomized design. The result showed that the mean germination percentage of the control treatment scored about 23.8%, followed by seeded rubbed by hand with a score of 15%. It is observed that room temperature has a significant effect (29%) on the germination of the control treatment compared to the incubator (18.7%) at p=0.05. However, no significant mean germination difference is observed between the effects of room temperature and the incubator in the remaining pre-sowing treatments: Washed with tap water (T1), 2) Washed and soaked in hot water for 15 minutes (T2) and 3) rubbing by hand (T3). However, it can be inferred that room temperature is an ideal temperature that meets plants' physiological seed germination requirement. To understand the importance of temperature and light on the germination of angiosperm, further experiments involving variable ranges of temperature and light intensity can be conducted.

The entrepreneurship aspect will determine the success of the development and development of rural ecotourism. Rural ecotourism products and services must be created and packaged by entrepreneurs in an attractive and highly competitive manner so that tourists are interested in consuming them. This study aimed to analyze the external factors that affect entrepreneurial capacity in rural ecotourism. The research location was in four tourist villages in Bogor Regency, namely Ciasihan, Sirnajaya, Watesjaya and Pabuaran Villages. Primary data was obtained through filling out a list of questions by respondents using a closed-ended questionnaire by applying the “one score one indicator scoring” system pattern . Data analysis was carried out in a quantitative descriptive manner based on the average value of each criterion/indicator. Analysis of causality between variables is carried out using logistic regression analysis. The results show that the external factors that significantly affect the performance of rural ecotourism entrepreneurship are dominated by social aspects (seven factors) and some aspects of the entrepreneurship ecosystem, namely 1) market, 2) finance and 3) business culture. The highest odds ratio is in the social interaction variable, which is 5.459, while the lowest odds ratio is in the group solidarity variable, which is 0.323. With the odds ratio of social interaction of 5.459, it can be interpreted that if social interaction in the tourist village increases, it will tend to cause the success in entrepreneurship 5.459 times higher than in the absence of social interaction.

Preservation effort to prevent tree collections loss even on aged trees (> 100 years old) is one of important missions in Bogor Botanical Garden since its establishment in 1817. Abiotic factors such as global warming and biotic factors from pests and diseases can threaten the survival of aged tree collections. Their survival is also influenced by plant health’s deterioration as they age. As the BBG has many functions not only for conservation but also for human ecological activities, fallen tree accidents are becoming primary concern to prevent biodiversity loss and people’s lives. We examined 154 trees health to determine a falling probability of 1106 aged trees based on several factors that caused to fall in the past and to make model prediction generated by nine supervised machine learning algorithms. We also classify susceptibility of tree families prone to fall from the highest accuracy of algorithm prediction. Inverse Distance Weighted interpolation method was used to depict zone map of trees prone to fall. The prediction showed that Random Forest model had the highest accuracy and low false negative (FN) value which were important to minimize error calculation on aged trees was not prone to fall but it turns out to be prone to fall. It predicted 885 trees prone to fall which 358 had high probability to fall. Fabaceae, Lauraceae, Moraceae, Meliaceae, Dipterocarpaceae, Sapindaceae, Rubiaceae, Myrtaceae, Araucariaceae, Malvaceae, and Anacardiaceae were tree families that were highly predicted to fall.

In addition to providing multiplier economy benefits, the tourism sector also has the potential to cause some latent and massive negative social impacts. For this reason, it is important to map out the orientation of the local community. This study aims to analyse the polarization of local community's perceptions about socio-cultural dynamics in the ecotourism development area. The local community that became the focus of the research consisted of five groups of respondents, namely traditional leaders, religious leaders, educational leaders, community leaders, and tourism actors. This research was conducted in the Bopunjur Ecotourism Area, Bogor Regency, West Java, precisely in seven ecotourism destinations, namely Ciawi, Caringin, Cibogo, Cipayung, Megamendung, Cisarua, and Tugu. This study used an exploratory – phenomenology approach. Data collection on social and cultural dynamics was carried out by distributing questionnaires to the respondents. The research instrument in the form of a questionnaire designed with a closed ended with guidance on one score one indicator scoring system. The results showed that positive social situations namely conducive situations, associations, cooperative situations, and productive collaborations were still more dominant than negative social situations: war, conflict, and dissociation. The polarization of local community on socio-cultural dynamics has a positive direction with a polarization scale that is aligned with each other so that there is a great opportunity to build productive collaboration between stakeholders in this area.

COVID 19 has brought significant damages to the lives of the people due to extremely long lockdowns and unemployment. Thus, leaving no choice to the residents but to depend their survival on what is available in the environment. This study was conducted to assess the contribution of the forests to the lives of the locals in Aurora through a survey on 161 respondents. Data were analyzed through descriptive statistics like frequency, mean, rank, and percentage. Results showed that 100% of the respondents depends on the forests for their food which includes fruits and vegetables in the wild and in their farms situated in the along and in the forest. Meanwhile, 116 individuals (72%) obtained livelihood from the forest in times of the pandemic in the form of labor, farming, selling of forest goods, charcoal making, and furniture making. Generally, the individual income obtained from forest livelihood ranged from Php500.00 to Php25,000.00 and an overall mean individual monthly income of Php4,084.19. Each type of livelihood activities provided a mean monthly income ranging from Php 4350 to Php 9021 per person. However, the respondents faced challenges such as loss of products due to theft, competition among those with the same livelihood due to limited number of consumers, and struggles concerning the health of the workers especially the elders, disabled, and other high-risk individuals to COVID-19. The government must consider providing needs (financial, technical, knowledge) to the locals in obtaining products and services from the forest for a sustainable utilization of the resources.

Indonesia has a natural tourist attraction in the form of 54 national parks spread across regencies and cities, with an area of 16,304,707.13 hectares, featuring a diversity of ecosystems, high mountains, lowlands, savannahs to wetlands, and waters. However, the appeal of natural tourism does not necessarily contribute to the performance of national tourism, hence studies need to support of increase in tourist arrivals to national parks, one of which is to study tourism competitiveness in areas that have national parks in Indonesia. This research aims to develop a model of tourism competitiveness management in areas that have national parks in Indonesia. The theory underlying this research is the theory of tourism competitiveness through the approach of the competitiveness index of the Travel & Tourism Competitiveness Index, Indicators for Measuring Competitiveness in Tourism, and Competitiveness Monitor. The research design uses 20 competitiveness factors, where data collection techniques utilize data that has been available at both government and non-government institutions and the data collection method uses library research. The data were analysed by using the dynamic model method. The results of the study found that tourist arrivals significantly correlated simultaneously with the factor of tourism competitiveness of the districts and cities that have national parks, tourist arrival, revenue tourism, and conservation in zona utility of national park in Indonesia. It is proposed that local governments, national parks management and other interested parties make policy innovations to optimize the factors of tourism competitiveness in their regions to support or increase in the number of tourist visits in national parks.
