Full text linkEx-limestone mining quarry has poor soil fertility, both biological, chemical, and physical condition due to the mining process. Marginal land conditions such as ex-limestone mining quarry require high survival seedlings. Application of ectomycorrhizal fungi is an alternative that can be done to improve the success of restoration. Acacia mangium is one of the plants that could be colonized by many types of mycorrhizal such as ectomycorrhiza. This research aimed to determine the growth of A. mangium seedlings in ex-limestone mining growth media and the effect of ectomycorrhiza application on the growth of A. mangium. The research used a completely randomized design with six treatments and five replications. Treatment consisted of 100% soil with mycorrhiza, 100% soil without mycorrhiza, 50% soil + 50% limestone tailings + mycorrhiza, 50% soil + 50% limestones tailings without mycorrhiza, 100% tailing with mycorrhiza and 100% tailing without mycorrhiza. The seedlings used in the study germinated from seeds taken from Lampung Timur Regency. The seeds germinated in sand for one month, then used as the research material. The measurement taken were height, diameter, number of leaves, leaf area, measured were root length, canopy dry weight, and total dry weight. The colonization of ectomycorrhiza is measured by counting the percentage of colonization. The symbiosis with rhizobium measured by number of root nodules. Data were tested for variance analysis, followed by Least Significance Different Test at significant level of 1% and 5%. The results showed that the percentage of A. mangium life was high, reaching 100%.

The majority of medicinal plants are dominated by awar-awar, while the lowest is the curcuma and pepper. There are quite a lot of medicinal plants in the area cultivated by KPPH Talang Mulya farmers, but there are medicinal plants which are threatened by populations such as temulawak, allegedly because they are used by the community without cultivation.Keyword: forest, forest park, medical plants
Analisis Status Hutan Kota Di Bandar Lampung (Analysis of the Urban Forest Status in Bandar Lampung City)
Full text linkUrban forest is one form of green open space. Urban forests play an important role in maintaining the sustainability of ecological functions in a city. This role could only run optimally with the availability of urban forests. The purpose of this study is to analyze the status of land ownership and analyze the efforts that can be made in maintaining urban forests. This study used image analysis, interviews, and field observations. From the results of this study, the status of urban forests based on the Mayor of Bandar Lampung Decree in 2010 had different statuses at each location. The urban forest ownership does not exclusively belong to the government. Of the 5 locations, only 1 location owned by the Bandar Lampung City Government, with 1 location that is not recognized (problematic), 1 location did not have a certificate of rights yet, and 2 other locations were private locations. The best effort that could be made to maintain the existence of urban forests is to control urban forest land as ownership in the name of the City Government with the support of certain regulations that can be done.

Keragaman dan Kelimpahan Artiodactyla Menggunakan Kamera Jebak di Kesatuan Pengelolaan Hutan I Pesisir Barat (The Diversity and Abundance of Artiodactyla Using Camera Traps in Forest Management Unit I Pesisir Barat)
Full text linkArtiodactyla is a wild animal that has an important role in ecology. The purpose of this study was to determine the diversity and abundance of species of order Artiodactyla in the Forest Management Unit (KPH) I Pesisir Barat. 19 units of camera traps were installed randomly within 14 observation stations (grid cells). Images of animals captured by camera traps on each grid cell were used to analyze the diversity and relative abundance of each species. The results of the diversity analysis showed that the Artiodactyla species found consisted of wild boar (Sus scrofa Linnaeus, 1758), muntjac (Muntiacus muntjak Zimmermann, 1780), lesser oriental chevrotain (Tragulus kanchil Raffles, 1821), sambar deer (Rusa unicolor Kerr, 1792), greater oriental chevrotain (Tragulus napu Cuvier, 1822), and Sumatran serow (Capricornis sumatraensis Bechstein, 1799). Species with the highest relative abundance were wild boar (42,33%) while the lowest was Sumatran wild goats (0,41%). The existence of Artiodactyla could play a role in maintaining the stability of the ecosystem particularly as a seed disperser and supports the presence of predators in the food chain process. Therefore, the KPH I Pesisir Barat forest areas as a habitat for wildlife must be sustainably managed.Keywords: Artiodactyla, diversity, abundance, camera tra
