Abstract

Lake Dendam is never a loticwaters with lots of human activities around the area. The high human activity around the waters has an impact on the quality of the waters and the organisms in the vicinity. This observation was carried out to obtain an up-to-date picture of water quality and micro-algae biodiversity in Revenge Lake for developing sustainable management strategies. Tests were carried out on the chemical and physical quality of the waters, and the biodiversity of microalgae which were then processed into an area management strategy. The results of the water quality test showed slightly polluted conditions with values of dissolved oxygen (DO), chemical oxygen demand (COD), total suspended solid (TSS), and phosphate which were still outside the water quality standards. However, conditions that can still be tolerated are peat waters. The microalgae biodiversity test showed the dominance and diversity of microalgae genera in the waters. The dominant genus is Nitzchia sp. From these results obtained six sustainable management strategies for Revenge Lake.   Keywords : Biodiversity, Dendam Lake, microalgae, water quality

Abstract

Penelitian ini bertujuan untuk menganalisis dinamika vegetasi dan perubahan ekosistem pada sistem ladang berpindah di Desa Puguk, Bengkulu. Sistem ladang berpindah tradisional di desa ini melalui tahap pembukaan lahan untuk pertanian dan pemberaan selama beberapa tahun sebagai upaya pemulihan ekosistem. Penelitian ini menggunakan metode pengamatan lapangan dengan teknik plot sistematik pada lahan berpindah dengan usia berbeda, yaitu 1, 4, 10, dan 26 tahun. Parameter yang diukur meliputi komposisi jenis, struktur vegetasi, suhu udara, intensitas cahaya, dan kelembaban. Hasil penelitian menunjukkan bahwa keanekaragaman jenis vegetasi meningkat seiring dengan bertambahnya masa bera, dengan lahan berumur 26 tahun memiliki 25 jenis vegetasi, lebih banyak dibandingkan lahan berumur 1 tahun yang hanya memiliki 1 jenis. Penurunan suhu dan intensitas cahaya serta peningkatan kelembaban udara pada lahan yang lebih tua juga mengindikasikan keberhasilan proses suksesi alami. Sistem ladang berpindah tradisional tersebut terbukti mampu memulihkan keanekaragaman hayati dan struktur hutan sekunder apabila siklus bera dikelola dengan baik. Hasil ini memberikan rekomendasi untuk mempertahankan masa bera yang cukup panjang dalam pengelolaan ladang berpindah guna menjaga kelestarian ekosistem lokal.

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.
