Abstract

Mangrove forests are one of the forests that have been damaged. Human activities on the coast often ignore the preservation of mangrove forests. Coastal and marine areas of Indonesia have the highest biodiversity in the world (mega biodiversity). The research method used is a descriptive method, namely a method that focuses on solving actual problems that exist today. Solving actual problems is carried out through stages of activities including; data collection, compiling, analyzing, interpreting and making conclusions. Based on the results of the analysis, it can be seen that the capture fisheries business carried out by fishermen can optimally improve the standard of living of fishermen, which is carried out through efforts to increase production and productivity with the support of government policies in the fisheries sector. In order to increase the contribution of income from fisheries businesses run by fishermen, it can be done by implementing efforts to increase productivity supported by improving the quality of results. Thus, the goal of national development to improve the welfare of fishermen can be achieved.

Abstract

Seblat Natural Tourism Park is substantial for the well being of Sumatran Elephant which provides suitable habitat in Bengkulu Province. The conversion of former production forest area with Particular Function of Elephant Training Center of Seblat into Convertible Production Forest Area of Seblat as wide as 710 hectares in 2011, and forest enroachment activities resulted in fragmentation of Sumatran Elephant habitat. This fragmentation led to the isolation of Seblat Natural Tourism Park and separation from surrounding forest area, which affects the species abundance of Sumatran Elephant. A study is required to understand the relationship between land cover change and dynamics of species abundance of Sumatran elephant during the period of 2011-2020. The study was conducted in the TWA Seblat with the area of ​​±7,768.36 hectares. Data used in this study were secondary data, particularly inventory data of Sumatran Elephants from the BKSDABengkulu which was obtained using the path transect method from patrol activities as many as ±228 patrols for ±1596 days, and land cover data which was obtained from the Directorate of Forest Resources Inventory and Monitoring, Directorate General of PKTL. Spatial analysis was carried out by performing topology test using ArcGIS 10.4 software and land cover classification based on SNI 7645:2010. Topology test resulted in 1 forest cover class and 6 non-forest cover classes. Statistical analysis carried out was multiple linear regression using the IBM SPSS 26 application by performing the Anova test or F test, and T test. The results of multiple linear regression analysis showed the correlation value (R) 0.753 indicated that there was close relationship between secondary dryland forest (X1) and shrubs (X2) with the dynamics of the species abundance of Sumatran elephant (Y). The contribution of variable X1 and variable X2 in influencing variable Y was56.7%, and 43.3% was influenced by other variables which unincluded in this study. The calculated F value is 3.935 with p value 0.081, andbecause the p value is higher than 0.05, simultaneously secondary dryland forest (X1)  and shrubs (X2) did not influence the dynamics of the species abundance of Sumatran elephant (Y). The calculated T value is 1.776 with value of p=0.126, because value of p is higher than 0.05, partially there is no significant influence between secondary dryland forest (X1) on the dynamics of the species abundance of Sumatran elephant species (Y). Determining the influence of shrubs (X2) on the dynamics of the species abundance of Sumatran elephant (Y) resulted in T value of 2.579 and value of p=0.042, with value of p is lower than 0.05 means that there were significant effect between the two variables.

Abstract

Keberadaan pohon peneduh sebagai ruang terbukak hijau di lingkungan kantor pemerintahan memiliki peran penting untuk meningkatkan fungsi ekologis maupun fungsi estetika. Sebagai fungsi ekologis, pohon peneduh mampu meningkatkan kualitas udara dan kenaekaragaman hayati, sedangkan dari sisi estetika mampu menciptakan keindahan lingkungan dan kenyamanan bagi masyarakat sekitar. Penelitian dilakukan di Lingkungan Perkantoran Pemerintah Provinsi Bengkulu pada bulan Mei – Juli 2017 dengan tujuan untuck mengetahui kenekaragaman jenis pohon peneduh pada Lingkungan Perkantoran Pemerintah Provinsi Bengkulu. Metode penelitian adalah metode sensus dengan mendata seluruh jenis pohon peneduh yang berada di area penelitian dan data dianalisis menggunakan indeks keanekaragaman. Jenis pohon yang ditemukan sejumlah 38 pohon dengan jumlah keseluruhan 390 batang pohon. Pohon yang paling mendominasi adalah pohon glodokan tiang (Polyatia longifolia Sonn.) dengan jumlah 86 pohon atau  22,05% dari keseluruhan jumlah pohon di area tersebut. Indeks Keanekaragaman H’ = 1,02 tergolong ke dalam kategori sedang. Pohon yang memiliki jumalh sedikit diantaranya adalah pohon petai cina (Leuceana loucocephala (Lamk.) de Wit), sawo duren (Chrysophyllum cainito L), sawo kecik (Manilkara kauki L Dubard), sengon (Pariserianthes falcataria (L.) I.C. Nielsen), dan waru (Hibiscus tiliaceus L), hanya ditemukan masing-masing 1 individu saja atau 0,26% dari total keseluruhan pohon.

Abstract

The estuarine of Sungai Hitam in Bengkulu City represents a sandy terrestrial ecosystem characterized by a diverse assemblage of ground cover species, which collectively contribute to the ecological functionality of the immediate environment. This study aimed to identify the structural characteristics, species composition, and species diversity of the ecosystem's constituent flora. Fieldwork was conducted from January to February 2018. Data collection involved the systematic placement of 1m x 1m quadrat plots at 20m intervals. Subsequent data analysis utilized the Important Value Index (IVI) and Shannon-Wiener Diversity Index (H') equations. The findings revealed the presence of 79 species distributed across 22 families of ground cover plants. Sphagneticola trilobata (L.) was identified as the dominant species within this area, attributed to its robust adaptive capabilities and invasive characteristics. Despite this dominance, the overall species diversity was classified as high, evidenced by a diversity index value of 3.21. This high index signifies a relatively stable community structure and considerable ecological resilience against environmental disturbances.

Abstract

ABSTRACT The prevalence of mental health problems among urban dwellers is triggered mainly by increased urbanisation and the pressures of modern life. One solution that is now widely considered is the development of healing forests, which are green areas that serve as natural therapeutic spaces for mental and physical health. The University of Bengkulu's main campus, situated in a lush green area, has excellent potential to develop a healing forest. This study aims to analyse the potential for developing a healing forest on the Main Campus of the University of Bengkulu, including identifying suitable areas, analysing the benefits that can be generated, and recommending sustainable management and environmental conservation strategies. Through a qualitative descriptive approach, data were collected through direct observation, interviews with relevant parties, and literature review. The results showed that, after evaluation, the location that qualifies as a healing forest is only in zone 2, specifically at the point where the green area around the UNIB Rectorate is located. However, other places have the potential to be developed into a healing forest. Based on an analysis of visitors' perceptions and preferences, it is suggested that each location has the potential to be a healing forest, with several recommendations provided. Developing a healing forest on this campus is expected to be a strategic step in creating an environment that supports the psychological well-being of the academic community and provides broader ecological benefits.

Abstract

Land cover changes in Bengkulu City have significant impacts on carbon stock dynamics, which play a vital role in climate change mitigation. This study aims to analyze carbon stock estimates resulting from land cover changes using remote sensing technology. Landsat and Sentinel-2 satellite imagery data were used to map land cover changes over a specific period, employing a supervised learning-based classification method. Further analysis was conducted to estimate carbon stocks using calculations from the ICLEI Calculator approach. The results of the study indicate a decrease in natural land areas, such as shrubland and mixed dryland agriculture, which declined by 4,236.5 hectares and 3,002.6 hectares, respectively. The conversion of these lands into settlements, plantations, and paddy fields led to a significant decrease in total carbon stocks from 340,095.55 tons in 2014 to 279,033.7 tons in 2024. Additionally, the spatial distribution of carbon stocks in the study area showed patterns correlating with anthropogenic pressures and urban spatial planning policies. The main factors influencing these changes include urbanization, plantation expansion, and land conversion for economic purposes. This study underscores the importance of sustainable land management to prevent ecosystem degradation and support carbon stock enhancement. Conservation efforts, ecosystem rehabilitation, and prudent land-use policies are strategic steps in maintaining carbon balance and mitigating the impacts of climate change.
