Abstract

Management of forest resources cannot be separated from the character attributes of the community. In the arena of community forest action, access to forest resources, which is a people's livelihood, is an important element. The study aimed to analyze the performance of the local community attributes towards community welfare and examine the stratification of community land ownership. This research was carried out in the qualitative descriptive analysis. The results of the analysis showed that 41.56% of the community forest farming groups classified as land-owners. Based on the strata of land ownership showed that 70% in the third strata, which was land-ownership of less than 0.5 ha. This study concluded that the institutional of local community was relatively low because not effective in regulating community behavior. These indicated by the low performance achieved on the welfare of the community, the low ownership of the area of arable land, and the level of welfare of the local community falls into the category of poor and low community education.

Abstract

The objective of this research was to determine the yield and chemical composition of Litsea cubeba essential oil harvested from different habitat types on Mount Papandayan, West Java, Indonesia. The methods used were determination of sample plots at each habitat, followed by laboratory testing. Leaf samples were taken from each plot, the oil was extracted in the laboratory using steam distillation, which was subsequently analyzed by GC-MS. The results showed that the yield of essential oil was high (2.76-9.33%). The three dominant chemical compounds found were eucalyptol (16.97-55.78%), α-terpinenyl acetate (7.27-20.44%), and sabinene (14.45-68.05%). The results confirmed the expectation that Litsea cubeba essential oils extracted from Litsea cubeba trees growing in various habitats on Mount Papandayan would show a variety in yield and chemical composition.

Abstract

Mount Geulis University Forest (MGUF) is a university forest area surrounded by eight villages and has close relationships with the surrounding community. With a very strategic position, MGUF is vulnerable to various pressures, especially anthropogenic ones. Other studies have shown that population, development, and the economy have an essential role in environmental degradation. Thus, understanding these three things becomes essential to determine the right strategy to reduce the level of vulnerability around MGUF. This study aims to analyze the level of community dependency on MGUF and the level of vulnerability of the community around MGUF. Community dependency was analyzed using perceived value dependency on livelihood, perceived value dependency on income, and perceived value dependency on participation level. Community vulnerability was analyzed based on the population growth index, built-up land index, and economic openness index. The results showed that the farmer community had a relatively high dependency on MGUF. The lower the income, the higher the dependency on MGUF, and the participation rate increases as the dependency on MGUF increases. Raharja Village has the highest population growth index of 123.75, Mangunarga Village has the highest built-up land index with a value of 75.11, and Jatimukti Village has the highest economic openness index with a value of 33.52. In general, the village with the highest composite vulnerability index is Cikahuripan Village, with a value of 0.71, and the lowest is Jatiroke, with a value of 0.20. Based on the value of the vulnerability index and the level of security, the level of vulnerability can be reduced by carrying out collaborative management to run programs with every stakeholder in the MGUF management system.

Abstract

Pulau Dua Nature Reserve has undergone significant changes to its land, affecting its physical and chemical properties. Additionally, the increasing problem of scattered plastic waste raises concerns about its negative impact on the ecosystem. This study aims to analyze the physical and chemical characteristics of Pulau Dua Nature Reserve and examine the relationship between the proportion of plastic waste cover area and environmental parameters. Microclimate, soil, and plastic waste proportion area data, especially plastic, were collected at 34 points using systematic random sampling, while water salinity was measured using accidental sampling because the pools for measuring salinity were not spread throughout the research area. A comparative analysis based on literature review and previous studies with mangrove ecosystems indicates that Pulau Dua’s mangrove vegetation is under threat from various environmental factors. Among these, the proportion of plastic waste cover area has the strongest correlation as moderate positive correlation with bulk density in Pearson Correlation Matrix. Independent Sample T-test comparing plastic waste cover area proportion based on bulk density class confirms that class 4 significantly affects bulk density. In conclusion, several physical and chemical parameters in Pulau Dua Nature Reserve do not align with optimal conditions for mangrove vegetation. The most related factors to plastic waste cover area proportion are bulk density because the indication is that areas covered with plastic waste are areas that are frequently passed by humans, thus increasing the bulk density of the soil. Value of bulk density will significantly different when proportion of plastic waste cover more than 2.5% based on Independent Sample T-test.
