Abstract

Pinus Jantho Forest (PJF) Nature Reserve has unique characteristics and distinctive ecosystem that plays an important role in the preservation of germplasm and the protection of natural resources. The sustainability of the PJF Nature Reserve is strongly determined by vegetation of its constituents. Therefore, an effort is needed to help its management properly, one of which is by knowing the diversity of plants that make up the community in PJF Nature Reserve. The purpose of this research is to analyze the composition and diversity of plant species in PJF Nature Reserve. Data collection and sampling were done using multiple square method. The plots were laid out by systematic sampling. PJF Nature Reserve composed of 111 species from 46 family. The seedling and understorey have the highest number individuals (1028 in total). Then there are 240 individuals at sapling level, 108 individuals at pole, and 72 individuals for tree.  The Euphorbiaceae family has the largest number of species (11 species). The highest Important Value Index (IVI) for seedlings and understorey, sapling and pole, and tree respectively were Chloranthus elatior (11.09%), Piper aduncum (21.90% and 19.32%), and Pinus merkusii (25.52%). The Diversity Index indicates a high level of plant species diversity (3.25-3.63).

Abstract

Research on analysis of macroalgae community structure on different substrates in Sabang waters to identify, analyzing diversity, abundance, and important value index. The data collection method was carried out by purposive sampling using a plot of 1x1 m2 with 10 plots per transect. Sampling was carried out at three stations, namely Station I on Pasir Putih with a medium fine sand substrate, Station II at Anoi Itam with a gravel sand substrate, and Station III on Rubiah Island with a fine sandy clay substrate. Data were analyzed using the Importance Value Index (IVI) and the Shannon-Wiener Diversity Index. The environmental parameters at each station that were measured were substrate particles, temperature, brightness, depth, and current velocity, while the chemical parameters were salinity, pH, COD, phosphate, and nitrate. The results of the study found 2615 macroalgae individuals consisting of three divisions. Chlorophyta division consists of 9 species, Rhodophyta was 7 species, and Phaeophyta was 1 species (Dyctyota dichotoma). The highest Important Value Index at each research station consisted of the Chlorophyta division with two species, namely Dictyosphaeria cavernosa (IVI = 59.18) and Halimeda opuntia (IVI = 54.15). The value of the diversity index (H') of macroalgae in Sabang waters is moderate, namely in Pasir Putih as much as 2.18, Anoi Itam and Rubiah Island as much as 2.01, and 1.97, respectively. The study concluded that the macroalgae community structure in Sabang waters exhibits moderate species diversity, with the Chlorophyta division, particularly Dictyosphaeria cavernosa and Halimeda opuntia, showing the highest importance value indices across different substrates.

Abstract

Community empowerment through eco-print training by utilizing local plants aims to improve the skills and knowledge of the community in processing natural materials into value-added products. The training focused on the eco-print technique, which is a natural printing method that uses the potential leaves and local plants to create unique designs on fabrics. By utilizing local resources, participants not only learn new skills, but are also expected to develop sustainable creative enterprises with cultural relevance. The program involves active participation from the community, allowing them to share experiences and knowledge by conducted hands-on workshops on the eco-print technique, as well as build business networks. The results of the training showed an increase in participants' abilities in eco-print techniques and understanding of the importance of environmental sustainability. Through this initiative, the community is expected to support the increase their income by facilitated collaboration and business network development among participants for long-term growth, preserve local plants, and contribute to cultural and environmental preservation.
