Motivation, Perceptions, and Preferences of Tourists Visiting National Parks on the Java and Sulawesi Islands
Get PDFUnderstanding tourist motivation, perception, and preferences is critical for designing effective tourism strategies in national parks. This study examines the relationship between ecological factors and the motivations, perceptions, and preferences of domestic tourists visiting national parks in Java and Sulawesi, Indonesia. Data were collected from 358 respondents via an online survey over four months and analyzed using chi-square and General Linear Model tests to assess socio-demographic differences. The main motivation for visiting national parks in Java was "attractive natural panoramas", while in Sulawesi, it was the "diversity of fauna". Tourists in Java exhibited stronger cognitive perceptions due to informative signage, whereas Sulawesi visitors appreciated the "natural appearance of facilities". Affective perceptions were consistent across both islands, driven by enjoyment, while conative perceptions were linked to intentions to revisit for wildlife observation. Activity preferences varied, with Java tourists favoring natural panoramas and Sulawesi visitors prioritizing wildlife observation. The length of visit was the only socio-demographic variable significantly related to motivations, perceptions, and preferences. These findings highlight the varying ecological priorities of tourists in Java and Sulawesi, with implications for targeted management and conservation strategies in national parks

Get PDFPuspa is a type of vegetation that can be used to restore forests, and grows in M Halimun Salak National Park. This study aims to analyze the species composition, stand structure and biophysical aspects of Schima wallichii (DC.) Korth. The research method used was vegetation analysis with purposive sampling of 5 plots measuring 50 x 50 meters based on the height of the research location. The results showed that puspa dominated the study site with high density at the seedling level and low at the tree level. The horizontal structure of puspa at the study site shows an inverted “J”, indicating that natural succession is well underway. The distribution of puspa in the plot shows a clustered distribution. The temperature and humidity of the study site were relatively uniform, the slope was in the steep and very steep class, while the thickness of litter and residual organic matter was relatively uniform, except in plot 2
Does the Tricolor Langur Truly Have a Specific Habitat in Danau Sentarum Landscape? An Analysis of The Preferences Habitat Using Maximum Entropy
Get PDFThe tricolored langur (Presbytis cruciger) is not only geographically restricted but is also believed to strongly depend on specific habitat types, particularly wetland ecosystems in northern Borneo. Despite its limited range and potential vulnerability, no comprehensive habitat assessment has been conducted within its distribution area. This study aims to model the habitat suitability of P. cruciger in the Danau Sentarum landscape using environmental variables derived from direct encounter data collected between 2021 and 2023, and analyzed using MaxEnt. Habitat suitability modeling revealed that 95.94% (228,658 ha) of the total study area (238,329 ha) was classified as unsuitable habitat. The remaining areas were categorized as marginally suitable (7,080 ha), suitable (1,977 ha), and highly suitable (614 ha). Highly suitable areas are concentrated in peat swamp forests, riparian forests, and lowland secondary forests located within 1 km of lake edges, extending into the hilly zones of the Danau Sentarum landscape. Among the environmental predictors, land cover contributed the most to the model, though it showed low permutation importance. In contrast, proximity to fire hotspots demonstrated high permutation importance, indicating an avoidance behavior towards fire-prone areas. The species preferred elevations ranging from 100 to 200 meters above sea level, with 8–25% slopes, and proximity to swamp forest and lake ecosystems. These results highlight the species\u27 strong association with wetland ecosystems and underscore the importance of conserving these habitats to ensure its survival
Factors Influencing Coastal Flooding from Akurala to Godagama in Sri Lanka
Get PDFOver the past decade, the Southwest coast of Sri Lanka has experienced recurrent coastal floods, particularly in the stretch from Akurala to Godagama. This study, spanning from 2010 to 2020, seeks to unravel the factors influencing these floods, filling a void in existing research on the subject. Employing topographic maps, field observations, and bathymetric data from the Lanka Hydraulic Institute and Coastal Conservation Department, the research delves into geomorphological features and elevation variations in the study area. Findings indicate that high elevation in the Ambalangoda to Akurala and Godagama to Hikkaduwa regions contributes to coastal flooding, as these areas are elevated above the mean sea level. The bathymetric analysis exposes closely spaced contours and steep slopes, exacerbating flooding when waves collide with the coastline. The absence of mangroves amplifies the impact, distinguishing the study area from its neighbouring regions. Socioeconomic consequences include road closures, accidents on the Galle-Colombo main road in 2020, and adverse effects on fisheries and tourism. Environmental impacts encompass coastal erosion, degraded water quality, coral bleaching, and saltwater intrusion. While artificial structures like rock barriers mitigate flooding, the study underscores the interplay of land morphology, bathymetry, land use, and climate influencing coastal flooding along the Akurala to Godagama coast
Agrobiodiversity of Talas Beneng (Xanthosoma undipes K.Koch) Based-Community Forest and Its Role in The Productivity Enhancement
Get PDFThe increasing intensification of agriculture, which tends to be monocultural and lacks attention to diversity, has led to global challenges related to climate change and sustainability by affecting carbon sequestration, land productivity, and farmers\u27 incomes. This study aimed to determine the role of agrobiodiversity in the talas beneng community forest in supporting sustainable agriculture that provides long-term benefits for the environment, economy, and community welfare. We conducted a case study on an agroforestry system based on taro cultivation in community forest land using a vegetation survey, observations, and interviews with three key respondents. The results showed that agroforestry-based taro cultivation has the potential to extend the timber harvesting cycle and maintain the ecosystem functions of community forests. Agrobiodiversity in community forest land based on taro cultivation is relatively low (H\u27 <3), but it can have a positive impact on agricultural land sustainability and potentially increase the local economy and farmers\u27 income
Wildlife in Disturbed Forests: Reptile and Amphibian Diversity in South Papua
Get PDFThe unavoidable economic development in Papua will certainly cause habitat changes. The logging activities in the production forest areas provide various habitat types with different typologies based on the clearing of areas for timber production and human access in each habitat. This research aims to analyze the diversity, richness, evenness, and similarity of reptile and amphibian communities in relation to the type of habitat disturbance in the Production Forest Area of Boven Digoel, Papua. Field surveys were conducted in June-July 2023, using active and passive survey methods in highly disturbed, moderately disturbed, and undisturbed habitats. The Shannon diversity index values of herpetological diversity in the three habitat types ranged from 0.75 to 1.94. Highly disturbed habitats have the lowest number of individuals and species of reptiles and amphibians. However, the common reptiles and amphibians are found in undisturbed habitats. Two species of protected reptiles were recorded in this area. This indicates that some species are at risk of extinction if action is not taken to conserve their habitats

The Estimation of Cuscus Population and Distribution in Teluk Wondama District, West Papua Province, Indonesia
Get PDFCuscus is a marsupial mammal endemic to the eastern part of Indonesia. Populations and their habitats are under pressure due to economic development, population growth and utilization of forest resources. So far, studies on cuscus ecology have mainly focused on protected habitats or conservation areas, this study aims to identify and analyze populations and predict the distribution of cuscus in non-protectes area which is PT Wijaya Sentosa. This research conduct in November 2020 until January 2021 in several land cover categories. The methods used in this study include literature and secondary data studies, field observations using strip-transect and camera trap techniques, interviews using purposive sampling techniques. This study found nine individuals of cuscus from direct observation with strip-transects and two individuals of cuscus from camera trapping. The ground cuscus population (P. gymnotis) had the highest abundance and density, while the common spotted cuscus (S. maculatus) population owned the lowest values. The population structure dominates by male sex and adult age class, and no female sex and young age class were found. Cuscus was more commonly found solitary in the line of observation and not found in every line. The shape of the distribution pattern of the cuscus population at PT Wijaya Sentosa is cluster/aggregated, determined from the value of the dispersion index and the ratio of variance to mean. The most common ground cuscus was found in the 2018 and the 2013 logging area (LOA)
Lead Level Analysis in Roots and Leaves of Mangrove Plants Ceriops tagal and Rhizophora apiculata in Clungup Mangrove Conservation
Get PDFIndonesia is an archipelago with more water than land, which is battling water and land pollution. One form of pollution is lead which is commonly caused by battery waste, fishing boat activities, diesel waste. One solution is phytoremediation using hyperaccumulator plants such as mangroves. Mangroves can absorb heavy metals and maintain ecosystem stability. The dominant species in Clungup Mangrove Conservation are Ceriops tagal and Rhizophora apiculata. The objectives of this study were: 1) To determine the level of lead metal (Pb) pollution in mangrove sediments in the area. 2) To determine the levels of lead metal (Pb) in the roots and leaves of mangrove species Ceriops tagal and Rhizophora apiculata. 3) To determine the ability of lead metal (Pb) absorption in mangrove plants Rhizophora apiculata and Ceriops tagal. Research activities began on February 20th - May 31th, 2023. The research was conducted at Clungup Mangrove Conservation in Sumbermanjing Wetan District, Malang Regency. Lab tests were conducted at the Unism Integrated Laboratory and Halal Center. Lead test results in sediments in this area are classified as very low. Lead levels in the roots of Ceriops tagal were higher than Rhizophora apiculata. Pb levels in the leaves of Ceriops tagal were also higher than the leaves of Rhizophora apiculata. Bioconcentration Factor (BCF) values were higher than Rhizophora apiculata, but both were categorized as lead removal plants (BCF < 1). The Transfer Factor (TF) value showed a lower value for Ceriops tagal than Rhizophora apiculata, indicating that Rhizophora apiculata has better translocation ability. However, both are categorized as unstable plants (TF < 1). The results of the phytoremediation calculations showed that Ceriops tagal had superior absorption potential compared to Rhizophora apiculata
