Abstract

Rafflesia patma is an endemic plant of Pangandaran, West Java which is protected because of its rare status. The purpose of this research is to study the population structure, distribution patterns, and the effect of the physical environment of abundance R. patma in Pananjung Pangandaran Nature Reserve, West Java. The method used in this research was a survey method with a purposive sampling technique. Sampling was conducted using quadrat plots. The population pattern distribution was defined by a standardized Morisita index, and the analysis of abiotic environmental factors was determined by Principal Component Analysis (PCA) using PAST3. The results showed that there were 114 R. patma individuals scattered in several research areas in Pananjung Pangandaran Nature Reserve, they were Gua Parat (3 individuals), Cilegon (13 individuals), Pasir Putih (12 individuals), Badeto (48 individuals), and Curug Leutik (38 individuals). The distribution pattern of R. patma in Pananjung Pangandaran Nature Reserve was clustered with the Morisita index value (Id) > 1. Based on the PCA analysis, results that support the classification of the cluster analysis were obtained. Based on four abiotic environmental conditions analyzed, the most dominant character in influencing the distribution patterns and population structure of R. patma is light intensity.

Abstract

Soil arthropods play an important role in nutrient cycling and maintenance of soil structure. Thus, their abundance and diver­sity can indicate the biological quality of the soil. Due to different soil management practices, arthropods are also very sensitive to en­vironmental changes. This study aims to analyze the abundance and diversity of soil arthropods and the environmental factors that sup­port the abundance of soil arthropods in terrestrial of Situ Lengkong Panjalu, West Java, Indonesia. The methods used to obtain samples of soil arthropods are pitfall trap. Soil arthropod data were analyzed to determine the Shannon diversity index (H'), Margalef richness index (R), and Evenness index (E). The effect of abiotic environmental fac­tors was analyzed using Principal Component Analysis (PCA). A total of 1263 arthropods were found in Situ Lengkong Panjalu, belonging to 11 orders, 24 families, and 32 morphospecies. The current work determined the scores of H'= 2.08, R = 3,08, and E = 0.72 of soil arthropods in Situ Lengkong Panjalu, West Java, Indonesia. Results revealed that humidity is one such environmental parameter affecting the presence of soil arthropods in Situ Lengkong Panjalu, West Java, Indonesia. This research can be used as a guide in validating and conservation of the habitat of soil arthropod species on West Java

Abstract

Rafflesia patma Blume is a plant endemic to Pangandaran, West Java, which is protected because of its rare status. This study aims to study the composition of the floristic vegetation that supports the life of R. patma in the Pananjung Pangandaran Nature Reserve, West Java. The research was conducted using a survey method with a purposive sampling technique and sampling using quadrat. The data obtained were then analyzed using the Importance Value Index (IVI), Shannon-Wiener index, and Evenness index. The results showed that R. patma in the Pananjung Pangandaran Nature Reserve lived as a parasite on the roots and stems of Tetrastigma leucostaphylum. The floristic composition of the habitat of R. patma in the Pananjung Pangandaran Nature Reserve, West Java, consisted of 251 individuals divided into 28 species. The plant species with the highest Importance Value Index (IVI) were Syzygium antisepticum, Stephania capitata, Casearia sp., and Buchanania arborescens for the sapling category, as well as Syzygium antisepticum and Vitex pubescens for the tree category. The condition of the vegetation around the habitat of R. patma is quite dense with the diversity index values obtained belonging to the moderate level of diversity. The highest diversity index at the sapling level was found at the Cilegon location with an H' value of 2.14 and the highest diversity index at the tree level was found at the Gua Parat location with an H' value of 1.5.

Abstract

Climate change affects forests both directly and indirectly through disturbances. Disturbances are a natural and integral part of forest ecosystems, and climate change can alter these natural interactions. When disturbances exceed their natural range of variation, the change in forest structure and function may be extreme. Each disturbance affects forests differently. Reducing Emissions from Deforestation and Forest Degradation (REDD+) is a global initiative aimed at curbing carbon emissions from forest cover change. Indonesia, one of the most biodiverse places on the planet with the third largest extent of tropical forest, has been extensively involved in REDD+. Despite commitments from the government of Indonesia and the international community, the deforestation rate has not stabilized or decreased in the years since REDD+’s introduction in 2007. Although there is an extensive body of literature on REDD+, the need for grounded observations from the field could clarify existing challenges and inform future pursuits. Challenges identified for each criterion include a lack of sufficient funding opportunities, inability to enforce boundaries due to corruption, and lack of a solid plan for involving communities. Carbon sequestration and biodiversity preservation results were mixed because of a lack of monitoring and problems with encroachment. We argue that changes must be made to Indonesian policy to help enable the enforcement of project boundaries, monitoring technologies should be utilized, and stakeholders, particularly at the national level, need to address some of the challenges discussed to achieve effective REDD+ outcomes in the future.
